Installing NP-View Desktop

NP-View is designed to run on a Windows 10 or Windows 11 with a recommended configuration of a 10th Gen Quad Core Processor and 16GB of RAM.  This configuration should be sufficient for processing large data files up to 500,000 lines.  Simultaneously loading and analyzing multiple devices with larger configuration files will maximize the use of available system resources and additional RAM may be required.

Installation Process

  • Sign up on the Portal website to download the latest version of NP-View Desktop and to download a license key.  A SHA256 checksum is supplied with each download.  You can calculate the checksum on the files you download to verify the integrity of the files:
    • Windows Powershell: Get-FileHash /the/full/path/to/your/filename.exe | Format-List
    • Linux: sha256sum /the/full/path/to/your/filename.Appimage
    • macOS 11: shasum -a 256 /full/path/to/your/filename.app
  • Windows 10/11:
    • Launch the Windows installer with a double click.
      • User may need to adjust UAC (User Access Controls) depending on security settings.
    • The only dependency required on Windows is .NET framework 4
    • Once installed, NP-View will automatically launch.
    • Allow ports for private/public network if prompted.

NP-View has been designed to run offline, which means that the network connections attempted towards a public NTP server, the local DNS server, and the Network Perception update server are optional and do not affect the system if the internet is unavailable. More information on configuring NP-View can be found here.

Installing NP-View Server

NP-View Server has been designed to be easily installed by a single person who has moderate Linux skills. This article provides step-by-step instructions on the installation process, which includes:

  1. Provisioning a server
  2. Downloading NP-View server
  3. Installing NP-View server
  4. Installing a SSL Certificate

NP-View is accessed through a web browser (Edge, Chrome, Firefox) running on a modern operating system (Windows 10 or later, macOS 11 Big Sur or later, Ubuntu 20 or later) with a recommended configuration of a 10th Gen Quad Core Processor and 16GB of RAM.

Provisioning a Server

The following table documents the CPU, memory, and disk requirements based on the number of network device configuration files monitored by NP-View server:

Number of network devices monitored (firewall, router, switch) / concurrent users Min. CPU Memory Disk Space
Up to 50 devices / 3 concurrent users 4-core 16GB 200GB
Up to 100 devices / 5 concurrent users* 8-core 32GB 400GB
Up to 500 devices / 10 concurrent users 16-core 64GB 2TB
Up to 1,000 devices / 20 concurrent users 32-core 128GB 4TB

Greater than 1,000 devices please contact support to discuss requirements.

Recommended as the minimum for most Professional Server users.

Note: loading and analyzing devices utilizes the majority of the CPU and Memory capacity.  The higher the server capacity and the faster the CPU, the faster devices will load and be analyzed.

Firewall Rules

The source IP should be the client workstation that will access NP-View and the destination IP should be the NP-View Linux server.

Downloading NP-View Server

Sign up on the Portal website to download the latest version of NP-View server and the license key.  A SHA256 checksum is supplied with each download by clicking on the “show checksum” link.  You can calculate the checksum on the files you download to verify their integrity:

  • Windows 10/11 using Powershell: Get-FileHash /the/full/path/to/your/file/name/extension | Format-List
  • Linux: sha256sum /the/full/path/to/your/file/name/extension
  • MACOS: shasum -a 256 /full/path/to/your/file/name/extension

Installing NP-View Server

NP-View server is a Linux application. It can be installed on a virtual machine or physical hardware. There are 2 package formats available:

  • NP-View Virtual appliance (~2GB OVF) that works on all major hypervisor with support for the .vmdk disk format (e.g., VMWare ESXi).
  • NP-View Linux installer (~600MB) that works on all major Linux distributions on which Docker can be installed

The NP-View OVF uses Ubuntu Server 22.04 LTS or later. Root access is provided (see the text file provided with the .OVF) so the operating system can be periodically updated. This option should be used for new installations. The NP-View Linux installer is used to update NP-View on an existing system or for a new install on a Linux server.

Note: Network Perception does not recommend running NP-View in a double virtualized environment (Linux VM encapsulated within a Windows VM) as the operation of connectors, notifications and external interfaces can be unpredictable.

Option 1: Using the NP-View Linux Installer

Once downloaded from the portal, follow the steps below to complete the install:

  1. Move installer to server – This may require ssh or other user account permissions
    1. Place the file in a location you can access from the terminal
    2. /tmp – this is a temp folder available at the root directory
    3. /opt/np-live – this is the default NP View server root directory
  2. You can use the “ls” command to see what is in your current directory
  3. Log into the terminal or use SSH (Putty, PowerShell, etc.) into the Linux server
  4. Set root level permission with the command (this will allow you type commands without adding “sudo” to each command)
    • sudo -I
  5. Navigate to the directory in which the NP-View Server Linux installer was placed
    • Use the ls command to verify file is in this directory
  6. Run the installer with the command (Docker must be installed before this step)
    • Example: sh NP-View_Full_Filename.sh (example: NP-View_Server_Linux_4.0.5-add6)
  7. The installer will begin by checking for a running instance of Docker and internet connection
    • If Docker is not installed and running the installer will stop and you will have to manually install the latest version of Docker before continuing
    • If an internet connection is available and Docker isn’t installed, the installer will automatically download and install the latest version of Docker
    • If an internet connection isn’t available but Docker is installed, the installer will continue offline (Most Common Scenario)
    • If you are installing NP-View Server on Red Hat Enterprise Linux, use the following commands to install docker:
      • yum update
      • dnf config-manager –add-repo=https://download.docker.com/linux/centos/docker-ce.repo
      • dnf install –nobest docker-ce
      • systemctl disable firewalld
      • systemctl enable –now docker
  8. Follow the prompts during installation
    • Prompt to continue with offline installation
    • Prompt for default directory (/opt/np-live) We recommend keeping the default directory but it can be changed if preferred
      • Note: If the default directory is changed, then it will need to be edited for each new release during the installation
  9. There will be a message once the installation is complete
  10. Launch a browser to navigate to the NP-View User InterfaceExample of transfer with WinSCP:
    • Load WinSCP – It should default to this screen:
    • Default “File Protocol:” to SFTP
    • Fill in Host name, User name, and Password.
      • Host name would be the same as your NP-View Server IP Address
      • User name and Password are the same as the sudo credentials you use to log into the NP-View Server terminal.
    • Find the NP-View Linux Server Installer file in the left window. Then in the right window from the “root” select the “tmp” folder. Once you have completed both steps then click “Upload”.
    • Click Ok to complete the transfer.

Option 2: Using the NP-View Virtual Appliance

Once the Virtual Appliance OVF file has been downloaded from the portal, follow the steps below to complete set up:

  1. Extract the .zip archive (right click on folder and choose extract all)
  2. Import OVF into hypervisor
  3. Update CPU/Memory/Disk Space to meet requirements stated in KB in the hypervisor settings
  4. Open README.txt from extracted folder for credentials
  5. Launch the appliance and log into terminal using credentials in README.txt
  6. NP-View Server shell script will guide you through updating the NP-Live password, the root password, and to reset encryption keys
  7. Once complete the NP menu will appear indicating the server is ready to use.
  8. Launch a browser to navigate to the NP-View User Interface

Note: A static IP may need to be configured before utilizing the user interface.

Installing a SSL Certificate

NP-View listens on both port TCP/80 (HTTP) and TCP/443 (HTTPS). For HTTPS, it uses a self-signed SSL certificate by default. Users can also provide their own SSL certificate by simply copying a valid .pem file into the NP-View db folder.  If using HTTPS, the best practice is to disable HTTP or forward HTTP to HTTPS.

The following command can be used to generate a valid .pem file:

openssl req -new -x509 -days 365 -nodes -out cert.pem -keyout cert.pem

To learn more about generating your own SSL certificate, please visit python documentation.

Please note that .pem file should include both the private key and the full certificate. If you received the private key and the certificate as two or more separate files, you can concatenate them into a single .pem file.

Setting the Virtual Appliance Time Zone

By default, the Virtual Appliance install creates the file `/opt/np-live/local-settings.yml`, set to America/Chicago.  This file needs to be updated to reflect your local time zone.  To change to a different time zone, log into the server using SSH and become root with the command sudo -i. You can then perform the following updates.

Update TZ= to a value from timedatectl list-timezones

version: '3.4'

x-environment-tz: &timezone    

     TZ=America/Chicago

services:  

      manager:    

           environment:        

                 - *timezone  

      report:      

           environment:        

                 - *timezone  

     webserver:      

           environment:        

                 - *timezone  

      redis:      

            environment:        

                 - *timezone  

     monitor:      

           environment:        

                 - *timezone

Once you have set the new time zone, you can restart NP-Live with the command /opt/np-live/stop_NP-Live.sh  and then /opt/np-live/start_NP-Live.sh

Additional Installation Information

Improving NP-View Server Performance

Please reference minimum requirements, the higher the resources the better the performance.

Troubleshooting Disk Space

If a server upgrade or restart fails due to lack of disk space, please perform the following clean-up procedure:

  1. sudo rm -f /opt/np-live/db/log/system/nplive.log.*
  2. sudo docker system prune –volumes
  3. sudo rm /opt/np-live/docker-compose.yml.backup

NP-View does not automatically delete log files, the Linux system admin may wish to schedule the above commands in a periodic CRON job to maintain optimal performance.

If server upgrade or restart issues continue to occur, please reach out to the Tech Support team.

Default Disk Encryption

As the NP-View OVF is typically installed within a secure environment, the disk is not encrypted by default for data at rest.  The Linux Admin can encrypt the system drive for increased security knowing that system performance will be slightly degraded to accommodate the data decryption and encryption.

Personalize the Login Page

To add a custom message to the login page, a NP-View administrator can edit the file /opt/np-live/docker-compose.yml with the following entry in the webserver environment section: “- banner=Welcome to NP-view”

For NP-View, the file ~/Documents/np-live/config.ini can be edited to add: “banner=Welcome to NP-View”

Upload File Size Limit

When users upload a file through the Web user interface, NP-View will enforce a maximum file size which is 200MB by default. To change it, a NP-View Linux administrator can edit the file /opt/np-live/docker-compose.yml with the following entry in the webserver environment section: “- MAX_IMPORT_SIZE=209715200”.  The value is in bytes, so 209715200 corresponds to 200MB.

Backing up the NP-View Server Database

  1. Stop the NP-View Server (you can use the script /opt/np-live/stop_nplive.sh)
  2. From the NP-View Server folder (by default: /opt/np-live/, run the command: tar -zcf db_backup_$(date '+%Y_%m_%d').tgz db (this command may take few minutes to complete)
  3. Run the new release installer, which will update the containers and then launch NP-View Server

Complete Removal of NP-View

If you wish to completely remove NP-View from you server to start with a fresh install, perform the following steps:

  • Stop NP-View using the script /opt/np-live/stop_NP-Live.sh
  • Remove Docker containers using the command docker system prune -a as root (WARNING: this will completely reset Docker, so if non NP-View containers have been added they will be deleted as well)
  • Remove the NP-View folder with the command rm -rf /opt/np-live as root (WARNING: the NP-View database will be permanently deleted)

Product Tutorials

1. Network Mapping

Network mapping provides the Networking Team (Network Engineer, Network Security) with capabilities that allow users to:

  • Visualize an accurate topology of the network architecture
  • Identify and label critical cyber assets and critical network zones
  • Easily review which devices are protecting which network zones

Visualize Topology

NP-View can be used to discover your network topology and the underlying control plane, including layer-2 and layer-3 configurations. Without leaving the topology map, you can review many aspects of the network’s design including Firewalls, Routers, Switches, Gateways, Networks, VPNs, Hosts and more.

Critical Assets and Zones

Each asset can be tagged with categories and criticalities as well as grouped into zones making it easy to review which devices are protecting which network zones.

Details On-demand

Selecting a node in the topology map will interactively display an information panel with detailed data about that node.

2. Firewall Ruleset Review

Firewall ruleset review provides Network Engineers, Network Security, and Compliance Analysts with functionality for:

  • Easy review of firewall access rules and object groups using the Access Rules and Object Groups reports.
  • Automatic identification of configuration risks using the Risks and Warnings report.
  • Validating recent policy modifications as part of a configuration change review process using the Change Tracking report.

How to Review Access Rules

An independent review of firewall policies has to be periodically conducted to ensure that network access rules are correctly implemented and documented. It is important because lack of access rule review leads to unexpected network access vulnerabilities.

  • Frequency: each time firewall policies are changed, and at least once a quarter
  • How to do it:
    • Step 1: given a workspace populated with network device configurations, open the Access Rule table from the main menu (top left)
    • Step 2: leverage the “Column Search” feature or the “Compare” feature to show the rules in scope of your verification
      • For instance, filter the “Device” column to only show rules for a specific device, or filter the “Binding (ACL)” column to only show rules bound to a specific interface, or use the “Compare” feature to only show rules added or removed recently
    • Step 3: review values for the source, destination, service, binding, risk, and description of each rule in scope
      • The “Description” column captures comment, description, or justification from the device configuration
      • The “Risk” and “Risk Criticality” columns are populated by NP-View during the automated risk analysis
    • Step 4: to identify rules that are not justified, sort the table by “Description”. Empty values will be shown at the bottom.
    • Step 5: to document your review process, double click on the “Comment” or “Comment Status” cells to add your own comment. The comment status can be either “Verified” or “To Review” or “To Revise”
    • Step 6: to save an evidence of your review process, export the table to Excel using the export options in the top right corner of the table

Access Rules Table

The Access Rules report provides the users with complete details on each Access Rule with the ability to add justifications and actions.

Object Groups

The Object Groups report provides the users with complete details on each Object Group with the ability to add justifications and actions.

Risks and Warnings

As modifications are made to the network, the Network Perception default Policies and Requirements identify potential risks.  The Risks and Warnings report provides the users with a summary of the potential risks and their criticality with the ability to add actions and comments.

Change Tracking

As modifications are made to the network and the updated configuration files are imported, the changes are logged in the Change Tracking table.

tracking table
3. Segmentation Verification

Segmentation verification provides the Networking Team and Audit Team with capabilities that allows users to:

  • Assess correctness of network segmentation
  • Identify risky network connectivity paths
  • Understand exposure of vulnerable assets

Network Segmentation Accuracy

NP-View be used to verify the accuracy of your network segmentation.

The connectivity matrix which is available from the device info panel can be used to verify open ports between devices.

Inbound and outbound connections can be verified for each network using the highlight paths function.

Identifying Risky Connectivity Paths

Using industry best practices, Network Perception automatically identifies potential risks related to network configurations. Using the Network Perception  Connectivity Path analysis, the user can review each of the highlighted risks and make a judgment on action.

Exposure of Vulnerable Assets – Vulnerability Analytics

NP-View provides your security team with a single pane of glass for reviewing network vulnerability exposure. With the addition of scanner data or data from a vulnerability data service, vulnerabilities can be tracked across your network.

Topology Display of Vulnerabilities

When scanned data has been added to a workspace, and a topology view is built that also includes that scan data, nodes on the topology of that view will be marked with a shield indicating the presence of vulnerabilities.

These shields can be toggled on and off using the topology settings menu.

Device Panel Display of Vulnerabilities

Firewalls, Gateways, and Hosts may contain vulnerability and service information imported from scans. Clicking on any of these nodes in a View that contains vulnerability information, will display it in the info panel that opens over the main menu.

Clicking on the Vulnerabilities link will present a pop out with the vulnerability details.

4. Audit Assistance

Performing a regular review of your compliance metrics is important for your organization.  Performing the review manually is time consuming and tedious. Audit assistance provides the Compliance Team (Auditor, Compliance Officer, Compliance Analyst, and Consultants) with capabilities that allow users to:

  • Verify compliance with cybersecurity regulations and best practices through Policy Review.
  • Seamlessly store evidence for compliance review with Change Tracking.
  • Easily prepare compliance reports using the Audit Assistants listed below:

Workspace Report (Standard)

The Workspace Report assistant is available within each workspace and will generate a report for a specific view that includes detailed information about configuration files that were imported and parsed including:

  • Configuration assessment report including risk alerts
  • Ports and Interfaces
  • Access rules
  • Object groups
  • Path analysis

Industry Best Practice (Premium)

The Best Practice assistant requires a license to activate. This report is available within each workspace to generate a report for a specific view that includes the following topics:

  • Parser Warnings and potential misconfigurations
  • Unused Object Groups
  • Access Rules missing a justification
  • Unnamed nodes
  • NP Best Practice Policies on access rules and CiS Benchmarks that have identified potential risks
  • ACL’s with no explicit deny by default rule

NERC CIP Compliance (Premium)

The NERC CIP assistant requires a license to activate this function and guides the user through the steps required to create a report covering CIP-005 requirements. The NERC CIP audit assistant is only available within a NERC-CIP workspace and allows audit teams to classify BES cyber assets as High, Medium, and Low based on the standards. We have added a category for untrusted (Internet, Corp, etc.) to tag non BES assets. NP-View allows compliance teams to collect and report evidence related to the following requirements:

  • CIP-002 – BES Cyber System Categorization; impact rating and 15-month review
  • CIP-003 – Security Management Control; cyber security policy
  • CIP-005 – Electronic Security Perimeter; remote access management
  • CIP-007 – System Security Management; ports and services
  • CIP-010 – Change Management and Vulnerability; configuration change management, configuration monitoring, vulnerability assessment

Identifying Risks

Risk and Warnings are generated using Policies and Requirements located in the Policy Manager.  NP policies and requirements are automatically assigned to all devices when they are imported and run when network device configuration changes are identified.

The following default policies are provided for all Compliance modules:

  • Default Parser Risk Policy – triggers from device configuration file parser log.
  • Default Access Rules Risk Policy – triggers from access rules report

CiS Benchmarks are provides as part of the Best Practices Module

  • CiS Benchmark for Check Point
  • CiS Benchmark for Cisco
  • CiS Benchmark for Juniper
  • CiS Benchmark for Palo Alto

Policy Management

Each policy is broken down into a set of requirements that are used to identify potential network risks. Review the details of the Policy Manager in this section.

Risk Assessment Grading

At any given time, a monitored device can have one or more open risks or warnings. This information is used by our Grading algorithm to provide each device with a letter grade. The quantity, criticality and type of open risks and warnings go into the calculation.

This grade informs the users which devices have the highest security or compliance risks. The lower the letter grade, the higher the risk.

The grade for each monitored device can be seen by clicking on a device on the topology map and reviewing the Risk Assessment Grading on the device menu. Clicking on the menu item displays the details that went into the grade.

An depiction of the data flow is as follows:

Calculating Device Risk Grade

+

The Device Risk Grade is calculated using the following weights:

  • High = 5
  • Medium = 3
  • Low = 1

The Device Risk Grade is calculated using a simple equation, for example: (5 high * 5) + (1 low * 1) = 26 -> 100 – 26 = 74 -> C

  • 90 -> 100 = A
  • 80 -> 89 = B
  • 70 -> 79 = C
  • 60 -> 69 = D
  • Else F

Issue Status is used to exclude both Resolved and Fixed issues from the calculation.

Importing and Exporting Data

NP View supports several different methods of importing a variety of both primary device data, such as firewall configurations, and auxiliary data, such as hostname files.

Note: The Windows API has a maximum path length of 256 characters.  When importing files into NP-View with long file names (typically > 50 characters), they may fail to import.  Reducing the length of the file name before importing tends to resolve this issue.

Importing Primary Data

Once a workspace is created, the user can begin importing configuration files from Firewalls, Routers and Switches, and/or auxiliary data, such as hostname files. Multiple supported configuration files can be loaded at a single time.

Import can be done via several methods. These methods are Drag and Drop, Main Menu Import, or Automated Import on a schedule Via 'Connectors'

Drag and Drop

A blank workspace, ready for files to be dragged onto the topology. Doing so will engage the Main Menu Import function

Main Menu Import Function

Open the Main Menu and select Import Data

The Home View, with Main Menu open and Import Data selected

The Import window will open where you may add files. For Management Systems (Ex. Panorama) and also for Auxiliary Data, a second step will be presented to the user to allow them to view the entire list of data, and select a subset for import. For Panorama, it would show a list of all the devices contained in the files uploaded and allow the user to choose a subset of these devices to actually add to the workspace.

Import Window Opened

When files have been added, devices have been selected, and the user has chosen to click next; the files will be moved to the in progress tab.

The in Progress Tab

When your files are completely processed they will move to the Uploaded tab. Users can view the history of all of their imports in the Uploaded tab at any time.

Automated and Scheduled Import via Connectors

Automatically – NP-View can also be configured to automatically retrieve files from devices, network management systems, and file shares on a schedule to keep your environments more up to date.  See the Connectors section for more information on how to get started.

Note: Import can take some time depending on the number and size of the files imported.  The import status will be displayed by the background task spinner next to your user name in the upper right corner of the map. Upon completion of Import, the Home View of the Topology Map will be displayed.

Note: Device licenses are applied on First import.  As files are loaded, the available license count goes down and the device is tracked across all workspaces.  See the licensing section for more details.

Device Identification

When  importing a device, NP-View uses a built-in device classifier to figure out what kind of device it is using device heuristics. However, because many devices can use the same configuration file, this can be tricky. For example, different Cisco hardware can run the same Cisco IOS, but the configuration file doesn’t tell you which hardware it is.

The device classifier tries to distinguish between routers and firewalls by looking for syntax differences like how static routes are expressed. But this isn’t always accurate since routers can use dynamic routing instead of static routes.

By convention, the NP-View device classifier will classify a device as a firewall if the configuration contains access lists. If the app misclassifies a device, the user can change the device type using the info panel for that device.


An open info panel with Device Type Selector

Importing Auxiliary Data

This table lays out the various types of Auxiliary Data NP-View accepts, and the order in which they should be prioritized for import. Primary Devices are considered Priority 1.

Once the relevant configuration files (priority 1) are loaded, auxiliary data may be added to a workspace to enrich and augment the analysis and topology visibility.

Each workspace can only handle one file of each auxiliary type at a time.  This was done to support change tracking of hosts on the network.  When a new file is uploaded, it completely overwrites the older file of that type regardless of the creation date of the file.

As multiple files can have similar data, we have implemented a data priority to facilitate data enrichment and prioritization of data importance within the system.

Priority File Types Content
2 Scanner: nessus CVE info (ID, severity, Exploitability, Remediation suggestion)
3 Scanner: nessus Host Discovery (IP, HW Address, status), OS and Services
4 ARP MAC Address, Host
5 hosts (user created) Text (IP / Hostname)

Please see the auxiliary data section for information on file types and structures for the file types.

Export Workspace Data

NP View allows for several different methods of exporting different types of workspace data.

Export Comments and Metadata (for enrichment and reimport)

The entire Access Rules and Object Groups table and its contents can be exported to an Excel formatted document. The export will only contain the visible columns in the report.

It is important to keep the comments columns (Comment, Comment Author, Comment Status) as well as the Object Id column visible as they are required for subsequent import.

It is recommended that at least one row of data be manually filled in with metadata before export to fully populate the template with examples of the field format.

The upper right menu of the table

For Access Rules, there are three export options:

  1. Export to Excel – Exports visible cells to an excel file (.xlxs)
  2. Export to Excel with history – Exports visible cells to an excel file with comment history.
  3. Export to Excel with expanded objects – Exports visible cells to an excel file with expanded object groups and objects.

For Object Groups, there are two export options:

  1. Export to Excel – Exports visible cells to an excel file (.xlxs)
  2. Export to Excel with history – Exports visible cells to an excel file with comment history.

Once the export button is clicked, the file (rule.xlsx, or object.xlsx) will automatically download. The file will contain all of the visible table columns plus multiple columns of comment data.

Enriching Metadata

As part of the audit process, Comments can be updated for Access Rules and Object groups as discussed here. Once the primary and secondary data is loaded, the user may want to bulk load justification data into the Access Rules and Object Groups tables.

Access Rules

The access rules export will contain four columns of data for each comment as below.

Access Rules Comment Fields exported to Excel

  • Comment field contains the user entered text.  If cleared or left blank, the comment will be updated accordingly.
  • Comment Status choices are ‘Verified’, ‘To Revise’, ‘To Review’ or can be left blank.
  • Comment Author field contains the user who entered the last change.  Upon import, this field will be automatically populated with the userid of the importer. Manual inputs into this field will be ignored.
  • Comment Date field contains the date of last change.  Upon import, this field will be automatically populated with the current date if a change has been detected. Manual inputs into this field will be ignored

Object Groups

The Object groups export works the same as the Access rules except the Comment Criticality column will accept ‘Low’, ‘Medium’, ‘High’ or can be left blank.

Importing Metadata

Once the file is updated and saved, the user can use the +Import function or simply drag and drop the file into the workspace for upload.

Only metadata fields that have been added or changed will be imported.  A time stamp and username of the importer will be applied when imported.  The results will be viewable in the report after processing is complete and the report has been refreshed.  Updates to comment and metadata history, standard NP-View fields and expanded objects will be ignored upon import.

Note that the import keys on multiple fields to match data.  The following fields are required in the file to properly import.

  • Object ID
  • Comment
  • Comment Status
  • Comment Author
Interfaces Report

When was it introduced?

  • Beginning with NP-View Version 5.0 (release notes) users will now have access to a new feature called the Interfaces Report.

What does it do?

  • View Level Interfaces Report: Displays all information available for the interfaces in the View and their connectivity
  • Device Level Interfaces Report: Displays all information available for the interfaces on the selected Device and their connectivity

Where are they located?

View Level Interfaces Report: Available from the Main Menu

Device Level Interfaces Report: Available from a selected device’s Information Panel

Supported Devices & Data

Firewalls, Routers, Switches

The following table is a comprehensive list of supported devices. The instructions provided in the table can be used to manually extract data from the device for import. While we do our best to support the below devices, it is impossible for us to test the parsers with every possible device configuration combination. If errors occur during device import, Network Perception is committed to working with our customers to resolve their specific parsing issues.

Note that Network Perceptions device support policy follows that of the manufacturer.  When a manufacturer ends support for a product, so does Network Perception.  End of support devices are not removed from NP-View but will not be upgraded if issues arise.

Supported Devices with Vendor Partnership

The devices in this list are actively tested in our lab to support the most current versions of the manufacturer software. Network Perception has an active partnership with these vendors for software and support.

Additional Instructions

Collecting Data from the Device Console

+

Collecting configuration information from the device console can be an easy way to get the device data.

Following the below rules will help ensure success when importing the files into NP-View.

Note that not all data can be retrieved from the console. Please review the section for you specific device for additional instructions.

  1. Run the command from the console.
  2. Copy the text to a plain text editor. Do not use Word or any fancy text editor as it will inject special characters that we cannot read.
  3. Review the file and look for non text characters like percent encoded text or wingdings like characters. These will break the parser.
  4. Save the output of each command in a separate file and name it after the device so that NP-View can properly attribute the files. For example: firewall1_config.txt, firewall1_arp.txt, firewall1_route.txt
  5. For Palo Alto files, there are specific naming requirements, please see the Palo Alto section for additional information.
  6. Some config files contain very long strings. Line wrapping due to the window size of the terminal will break the parser. If using a terminal like Putty, please ensure the terminal is set to maximum width.
config system console
set output standard
end

Finally, if you encounter a parsing error when loading the files and want to upload the files to Network Perception using the portal, please sanitize all files at the same time so that we can keep the data synchroized across the files.

Berkeley Software Distribution (BSD)

+

BSD has three firewalls built into the base system: PF, IPFW, and IPFILTER, also known as IPF FreeBSD

  • Packet Filtering (PF): Rules located in file /etc/pf.conf
  • IP Firewall (IPFW): Default rules are found in /etc/rc.firewall. Custom firewall rules in any file provided through # sysrc firewall_script=”/etc/ipfw.rules”
  • IP Filter also known as IPF: cross-platform, open source firewall which has been ported to several operating systems, including FreeBSD, NetBSD, OpenBSD, and Solaris™. Name of the ruleset file given via command ipf -Fa -f /etc/ipf.rules

OpenBSD

NetBSD

BSD and similar systems (e.g., Linux) will use the same names for interfaces (eth1, eth2, em1, em2, carp1, carp2, etc.). The parser might be confused if the user imports interface files and packet filter configs from different systems at the same time resulting in a combined system instead of individual devices. To prevent this, the user should group all files by host, making sure to name the ifconfig file after the hostname (i.e. host1_interfaces.txt).

Free BSD Example

Below is an example of a 2 host FREE BSD system containing FW1, host1 and host2. The user should import the files in each section as a separate import. fw1 – first data set import (all available files imported together)

  • pf.conf (required file) (note, can be named differently, e.g., FW1.txt’)
  • obsd_fw1_interfaces.txt (required file) (note that the parser keys on the “_interfaces” string”. Text before “_interfaces” will be used to name the device. In tis example ‘obsd_fw1’)
  • hostname.carp1
  • hostname.carp2
  • hostname.hvm2
  • hostname.hvm3
  • hostname.hvm4
  • table1
  • table2

host1 – second data set import (all available files imported together)

  • pf.conf (required file) (note, can be named differently, e.g., host1.txt’)
  • host1_interfaces.txt (required file) (note that the parser keys on the “_interfaces” string”. Text before “_interfaces” will be used to name the device. In this example ‘host1’)
  • hostname.em1
  • hostname.carp1

host2 – third data set import (all available files imported together)

  • pf.conf (required file) (note, can be named differently, e.g., Host2.txt’)
  • host2_interfaces.txt (required file) (note that the parser keys on the “_interfaces” string”. Text before “_interfaces” will be used to name the device. In this example ‘host2’)
  • table1
  • table2

The only required files are the config file (can be named something other than pf.conf) and the ifconfig file. hostname files are optional (unless they contain description of interfaces not in the ifconfig file). Table files contain a list of IP addresses that can be manipulated without reloading the entire rule set. Table files are only needed if tables are used inside the config file. For example, table persist { 198.51.100.0/27, !198.51.100.5 }

Legacy Fortinet Support

+

Support for Fortinet through 6.2 ended September 2023. Please note that no upgrades to these parsers will be made.

Palo Alto Panorama & NGFW

+

Panorama

If Panorama is used to centrally manage policies, the access rules and object groups can be retrieved from these devices in XML format (we do not support the import of unstructured text files). If using the Panorama connector, the required files will automatically be downloaded:through 6.2 ended September 2023. Please note that no upgrades to these parsers will be made.

The Panorama file will only contain centrally managed access rules and object groups.

Locally defined access rules and object groups cannot be retrieved from Panorama and must be retrieved from each NGFW. Please follow the instructions below to export directly from the Next Gen FireWall using API.

Palo Alto Firewalls will ALWAYS have a V-sys even if one has not been configured it will default to vsys1.

The “mapping_config” file is required which can only be retrieved through the API using the “show devices connected” command.  The name of the file is “named_mapping_config.xml” where the named prefix needs to match the device name as shown in the UI when the running_config.xml is imported alone. All files should be imported at the same time. Please see instructions below:

The below links are to the Panorama documentation for the required commands with examples. The links provide you with commands to run directly in the Panorama CLI. The images we provided are for using Postman or web browser use.

Get API Key


Get Panorama and device bundle Configuration



Get device mapping config


Once both the “<panorama_server>_running_config.xml” and <panorama_server >_mapping_config.xml” are gathered, please import them together in NP-View.

Next Gen Firewall (NGFW)

If using the PanOS connector is used to download files, the required files will automatically be downloaded:

The configuration information from the NGFW may be contained in several .xml files, <device-name>_merged_config.xml and <device-name>.vsys(n)_pushed_policy.xml.  There can be one vsys file per virtual interface. The naming of these files is important for the parser to merge them during import.  All files from a single firewall must be imported at the same time and in .xml format (we do not support the import of unstructured text files).  If any of the files are missing, improperly named or formatted, an error message will state that ‘File parsed but ruleset and topology were empty, aborting’ meaning they could not be linked to the other associated files.

An example of properly named files is below:

  • Chicago-IL-100-FW1_merged_config.xml
  • Chicago-IL-100-FW1.vsys1_pushed_policy.xml
  • Chicago-IL-100-FW1.vsys2_pushed_policy.xml

NOTE: If the NGFW is an unmanaged/standalone Palo Alto device it will not have a pushed_policy file. In this situation, the configuration .xml file can be downloaded directly from the firewall and loaded into NP-View.  The file name need not be changed when loading the file from a standalone firewall.

To manually export configuration files from an unmanaged firewall:

If the NGFW is managed by a Panorama, the API will be required to secure the necessary files:

Get API Key



Get PANos Firewall full configuration



Get Managed Firewall configuration

Virtual Routers (vrf) – Experimental Support

Virtual router (vrf) is a software-based routing framework in Palo Alto NGFW that allows the host machine to perform as a typical hardware router over a local area network. NP-View has added the experimental capability to detect Virtual Routers from Palo Alto devices (NGFW or Panorama) and present them in the Connector or Manual Import device selection screens. Virtual Routers will be treated the same as physical routers and will require a device license.

This feature is disabled by default and must be enabled prior to importing configurations containing virtual routers.

To enable the feature the NP-View Server admin will need to make a change to a system variable.

  • Stop the NP-View Server application.
  • in the docker-compose.yml file, change the enableVirtualRouters=False to enableVirtualRouters=True in three places within the file.
  • start the NP-View Server application.

For Desktop

  • Close the NP-View application.
  • In the file C:\Users\<username >\AppData\Roaming\NP-View\config.ini add enableVirtualRouters=True
  • Restart the NP-View application

Once enabled, the user will be presented with the option to select virtual routers from the connector in the device selection or upon manual import.

Legacy Palo Alto PanOS Support

+

Support for Palo Alto PanOS prior to V9.1 are no longer supported. Please note that no upgrades to parsers will be made for unsupported devices.

Dell Edge Gateway

+

The Dell Edge Gateway runs Ubuntu Core OS. The gateway uses IP tables to configure the local firewall. NP-View uses the following 4 files extracted from the Ubuntu server to generate the topology. This device is not a firewall but more of an application running device. It does have some security features but we suspect it would be behind a real firewall. The following data is needed to import this device.

  • iptables_rules → to get a device created, containing interfaces and rules
  • hostname_interfaces → associated with config above
  • arp_table → to get external hosts (ip + mac)
  • active_connections → to get routes

This is not a simple device to get data from, the following process must be followed:

1. Capture the iptables Filter Rules

To capture the iptables filter rules (the firewall rules that are active on the system), you can use the following command:

Show Command:

sudo iptables -L -v -n

Description:

Lists the currently active iptables firewall rules (filter rules). Includes details about chains (INPUT, OUTPUT, FORWARD), protocols, sources, destinations, and ports.

Save Command:

sudo iptables-save > ~/iptables_rules.conf

This will save the firewall (filter) rules in a file called iptables_rules.conf in your home directory.

2. Capture the Network Interface List

To capture the list of network interfaces (with IPs, MAC addresses, etc.):

Show Command:

ip addr show

Description:

Displays the list of all network interfaces on the system. Includes details about interface names (eth1, eth2, etc.), IP addresses, MAC addresses, and other interface attributes.

Save Command:

ip addr show > ~/hostname_interfaces.txt

This will save the interface details in a file called hostname_interfaces.txt in your home directory.

3. Show ARP Table

Show Command:

ip neigh show

Description:

Displays the ARP table, showing which MAC addresses correspond to which IP addresses on the network.

Save Command:

ip neigh show > ~/arp_table.txt

4. View Routing Table

Command:

ip route show

Description:

Displays the current routing table, showing default gateways, specific routes, and the interfaces used to reach specific networks.

Save Command:

ip route show > ~/routing_table.txt

5. Loading files into NP-View

Once all of the files have been retrieved, they need to be loaded into NP-View together and without any other files so they are properly associated.

Legacy Check Point R80 Support

+

Support for Check Point R80 through R80.40 ended April of 2024. Please note that no upgrades to these parsers will be made.

Cisco FTD

+

NP-View supports Cisco FTD through the output of “show running-config”command. However, it is important to note that Cisco FTD includes network filtering policies documented outside of the running configuration. This section explains where to find those policies.

As of version 6.1, Cisco FTD includes a Prefilter Policy feature that serves three main purposes:

  • Match traffic based on both inner and outer headers
  • Provide early Access Control which allows a flow to bypass Snort engine completely
  • Work as a placeholder for Access Control Entries (ACEs) that are migrated from Adaptive Security Appliance (ASA) migration tool.

The feature has 2 primary use cases:

  • For use with Tunnel Rule Types
  • For bypassing the Snort engine

These prefilter rules are part of the FTD configuration and are displayed via the “show running-config” command on the FTD. They manifest in the NP-View Access Rule table as a Permit IP with:

  • Source = any
  • Destination = any
  • Service = IP/any to any

As a result, the NP-View Rule Policy engine flags these rules as a high risk alert.

In the operation of the FTD, if a packet meets the prefilter policy, it is then evaluated by a secondary set of rules in the Snort engine or applied directly to the tunnel. The Snort rules are not part of the output of the of the “show running-config” output from the FTD. These rules are established, maintained and viewed on the FMC (management server), but are not readily available via the FTD CLI interface.

In the context of an audit during which evidence around these prefilter rules is requested, we recommend documenting that these rules are a default configuration for the system and we also recommend generating a FMC PDF Policy report to explain the flows of traffic within the FTD configuration. For more information, please refer to the Cisco FTD Prefilter Policies documentation.

SonicWall

+

We support .exp files as the default SonicWall file format for v5.9 and v6.X of the SonicOS.

The main UI allows for export of the encoded .exp file as such:

To extract the file via command line, then the command to export is

export current-config sonicos ftp ftp://[USERNAME]:[PASSWORD]@[FTP IP/URL]/sonicwall.exp

Where the username/password/FTP IP or URL must be changed. The file “sonicwall.exp” will then be saved at the FTP location. As this file is encoded, there’s no way to echo or cat the data.

Requesting Support for New Devices

The above list of supported hardware has been lab and field tested.  Newer versions generally work unless their is a major platform or API upgrade.  Please contact support@network-perception.com if you wish to get more information on parsers, request support for a particular device or are interested on co-developing a solution.

Connectors

NP-View includes a utility to automatically retrieve network device configuration files on a schedule. The connector types supported in NP-View Server are below:

Configuration Managers

For retrieving config files from network management systems. For each connector, the user can select the devices to be uploaded for monitoring.

Manufacturer Type/Model Configuration Information Required Connection Type
Fortinet FortiManager (6.4.x, 7.0.x) Hostname or IP address plus login credentials HTTPS + optional SSL server verification
Palo Alto Panorama (10.x, 11.x) Hostname or IP address plus login credentials See device selection section below for additional information HTTPS
SolarWinds Network Configuration Manager (Orion Platform HF3, NCM HF1: 2020.2.6) Hostname or IP address plus login credentials HTTPS

Direct Device Connection

For retrieving config files directly from the network device.

Manufacturer Type/Model Configuration Information Required Connection Type
Check Point R81.x Hostname or IP address plus login credentials See device selection and service account sections below for additional information HTTPS + optional SSL server verification
Cisco Adaptive Security Appliance (ASA 9.19) Hostname or IP address plus login credentials, enabling password and optional context SSH
Cisco Internetwork Operating System (IOS 15.9) Hostname or IP address plus login credentials, enabling password and optional context SSH
Fortinet FortiGate (FortiOS 7.0, 7.2) Hostname or IP address plus login credentials Note: SCP should be enabled in the configuration (instructions) SSH
Palo Alto NGFW (PanOS 10.x, 11.x) Hostname or IP address plus login credentials HTTPS

Volume Shares

For retrieving config files that are uploaded to a common collection repository.

Platform Connection Configuration Information Required Connection Type
Windows SMB Share (Samba) Hostname or IP address, share name, device name and root folder path SMB/CIFS
Linux SSH Share Hostname or IP address and folder path. Optionally an include list and exclude list can be defined. SSH

Additional Connector Information

Service Account

+

The use of service accounts is a recommended best practice when connecting to devices through connectors. The service account can be read-only and must have API privileges. When entering credentials related to an Active Directory domain, it is recommended to enter the username using the format account@domain.xyz instead of domain.xyzaccount as the backslash can cause unexpected issues.

Checkpoint

+

For the connector to work CheckPoint devices, the API setting need to be enabled in the SmartConsole.  See the image below for settings and commands to restart the API.

Device Selection (Palo Alto and CheckPoint)

+

CheckPoint and Palo Alto network management systems provide files with multiple devices. The connectors for these systems allow for the selection of individual devices to load into NP-View. The user can select the “Retrieve device list” button to be provides a selection list.

Collecting Layer 2 Data from Devices

+

Layer 2 data will automatically be downloaded by the connectors for Cisco ASA and Cisco IOS devices. If the data is manually collected, use the following commands and file naming conventions.

Cisco ASA
  1. show running-config → 'device_name'.'context_name'.txt
  2. show arp → 'device_name'_arp_table.'context_name'.txt
  3. show route → 'device_name'_route_table.'context_name'.txt
  4. show interface → 'device_name'.'context_name'.interface_table.txt
  5. show access-list → 'device_name'.'context_name'.access_list.txt

Cisco IOS
  1. show running-config → 'device_name'.txt
  2. show ip arp → 'device_name'_arp_table.txt
  3. show ip interface brief → 'device_name'_interface_table.txt

Once all of the files are collected, manually load the files from each device together and separately from other devices for proper file association.

Samba

+

Network Perception suggests the following when setting up the SMB connection.

  1. Create a read-only user in Active Directory or on the SMB server.
  2. Determine the available share (Get-SMBShare” in Windows PowerShell) or create a new one.
  3. Share the SMB folder containing the Configuration files with the read-only user. For example:

Configuration:

Lets assume that the server is at \\192.168.140.14\
  • the shared folder is named 'share'
  • and the files are in a sub folder of share called \test\NERC-CIP-EMS
  • a UNC would look like this: \\192.168.140.14\share\test\NERC-CIP-EMS
  • Per the above, the device name was set to LAB-SMB
When configuring the SMB connector, the screen would look like this:

If during the connector test, access is denied, the following settings should be verified and may need to be changed for the SMB to work as expected.

Running PowerShell as administrator

Input command Get-SmbServerConfiguration

Verify that EncryptData is set to false

If set to true, run command “Set-SmbServerConfiguration -EncryptData 0

Verify SmbServerHardeningLevel is set to 0

If not set to 0, run command “Set-SmbServerConfiguration -SmbServerNameHardeningLevel 0

Microsoft recommended default is off (0). More information about these settings can be found on the Microsoft website.

SSH and Samba for HA Groups

+

NP-View has the ability to handle HA Groups.

As a best practice, if using SSH or SNB shares, it is best to overwrite the entire folder with updated config files from the current active devices. It is also a best practice to name the HA devices similarly for comparison. For example:

Pittsburgh_FW1

Pottsbirgh_FW2

etc.

For Samba shares, a similar method should be followed.

Refer to the Samba section for details.

If you have a system for which you need a connector or if you encounter a technical issue, please contact support@network-perception.com.

Connectors automate the secure retrieval of configuration files from firewalls, routers, switches, and network device configuration managers. NP-View Desktop and Server can host one or more connectors that securely retrieves configuration files manually (desktop and server) or at the specified frequency (server only).

To access the connector function, use the system menu in the upper right corner of NP-View and select 'Manage connectors'

The connector function consists of several key features.

  • Password manager to reuse and manage passwords across multiple connectors.
  • Workflow for creating groups and connectors.
  • Automated data collection and download.
  • Flexible scheduling (Server only).
  • Runtime and scheduling status (Server Only).

The connector function supports the files devices listed on the connectors page.

Add Credentials

To get started, the user must first create one or more credentials. Credentials are used to access the devices and can be used for one or more devices. This provides for the ability to manage multiple devices with one set of credentials. Click the 'Add New Credential button to display the input section. Credentials are segregated by device type. Select the device type and input the required fields.

Once filled in, select the save button and the credential will be saved and displayed in the 'Credentials' box. Clicking on the credential will allow the user to edit the credential.

At this time, Deleting a credential is not supported.

Create Groups

Once credentials have been created, the user can proceed to creating a Connector Group.

Select the '+' in the 'Groups' section to display the add groups function. Fill in the group name, notes and select a schedule (server only). For desktop, only the 'On Demand' function will be displayed.

Once saved, the user can click on the connector group name in the 'Groups' panel to enter edit mode or select the three dots to the right of the name for individual group options.

Pull to run all associated connectors and delete to remove the group. Note that only empty group can be deleted.

Scheduling Groups

Groups can retrieve data on a schedule, when setting up or editing a connector group, the user can set a schedule.

The user has multiple options for scheduling the connector; monthly, weekly, and daily with flexible day of week and time options. We recommend that connectors be run at night to provide maximum resources for processing the data. When a connector group is scheduled, the next run status will be presented in the 'Groups' panel

and on the 'Processes' tab

Add Connectors

Once a group has been created, the user can add connectors to the group. In the connectors section, select the '+' to present the add connector function.

Proceed to select the connector type and fill in the required fields.

Next fill in the optional fields.

Filling in the name of a context will only fetch the data for that one context, leaving blank will fetch all contexts.

Selecting one ore more worspaces to deliver the fetched data. If left blank, the data will be retrieved for manual download.

The user can then test the connector to verify the credentials and/or save the connector.

Once saved, the user can click on the connector name in the 'Connectors' panel to invoke edit mode. Clicking on the tree dots next to the connector name provides individual connector options.

Manual Data Pull

Data from individual connectors can be retrieved manually by selecting the 'pull' option from the menu above. When selecting pull, the connector status will proceed to 'in progress'

and the processes tab will also display the progress status.

Once data has been pulled, the user can selectively download the most current data set from the connector panel.

Deleting Workspaces

If a connector is designated to deliver data to workspace and a user deletes the workspace, the connector will automatically be updated to reflect the workspace deletion.

Configuring Connectors (legacy)

In version 6.0, a new connector function was introduced. for new connector users, it is recommended to use the new connector function. The connector access has been moved from the +Import function to the system menu.

Connectors automate the secure retrieval of configuration files from firewalls, routers, switches, and network device configuration managers. NP-View Server can host one or more connectors that securely retrieves configuration files at the specified frequency. By default, connectors are accessible through HTTPS on port TCP/8443 of the NP-View server and is isolated for security purposes.

The first time an administrator accesses the connectors, they are required to define a Connector group name and a secure passphrase. The Connector group name will be used to create the encrypted connector file store. Connector information is encrypted at rest and in transit using a passphrase protected PGP key. Only the connector owners know the passphrase and the passphrase is never stored. Once initiated, connectors run in the background collecting network information.  If the NP-View server is restarted, the connector owner is required to re-authenticate and restart the connectors. Connector owners can create multiple connector groups and each will require their own login. Once created, the user can select from the list of available connectors when logging in.

The connector page contains five main options.

Add New Connector

The buttons from left to right are:

  • + Add New Connector
  • bulk start all connectors (see bulk start parameters below)
  • bulk stop all connectors
  • delete the connector (user must be logged into the connector group to delete)
  • exit the connector group.

Add Connector

To add a new connector, select “+Add New Connector”  button and a list of available connectors is presented. Connector options are: Cloud Providers, Configuration Managers,  Direct Devices and Volume Shares

Upon selecting the Connector type to add, the user is requested to fill in connection information. Connector information varies by vendor.  The connector configuration for a Palo Alto device is as follows:

The user must enter a Connector name (no spaces), host name, and credentials.  The user can then verify the credentials are correct with the “Test credentials” button.  The user can setup the polling cycle and provide the workspaces to deliver the resultant information.

Polling Cycles are:

  • On demand
  • Daily
  • Weekly
  • Bi-Weekly
  • Monthly

Configuration Management Systems

For Configuration Management Systems and file Shares, additional information may be required.  The user can retrieve a list of files from the device and filter the results.  To include specific files, put them in the include list field.  To exclude files, put them in the exclude list field.  If both lists are used, include list filter will be applied first and the exclude list filter to the results of the include list filter. If the share is PGP encrypted, a PGP Public key will be required.

Workspaces must be added to the connector for data to be transferred and displayed in the workspace.  If workspaces are added after a connector is setup, data will not be sent to the workspace until the next scheduled import and a configuration change is identified.  Creating workspaces before connectors facilitates faster visualization of data.

Connector Tile

Once the connector is added, a tile is added to the connectors home page.

Connector tiles are sorted by the characters in their names using standard Linux conventions:

  1. whitespace
  2. integer
  3. special char
  4. uppercase [A-Z]
  5. underscore (possibly other special chars)
  6. lowercase [a-z]

From the tile, the user can:

  • manually activate the connector for a one time data pull
  • run / pause the connector
  • edit the connector
  • copy the connector
  • delete the connector.

The tile banner will show in three colors:

  • red – connector failed
  • blue – connector scheduled to run
  • gray – connector paused

Click the start / pause button to restart a failed or paused connector, note that a connector may take several minutes to change the banner color.

Connector for Forescout

+

The Connector for Forescout 8.1 and later enables integration between CounterACT and NP-View such that network device configuration files managed by CounterACT can be automatically imported into NP-View and aggregated into specific workspaces. Currently, Cisco switches are supported through the Forescout Switch Plugin.

  • Download the Forescout Extended Module for NP-Vie from https://updates.forescout.com.
  • Start your Forescout Console and login into Enterprise Manager.
  • Then open “Options”, select “Modules”, and install the fpi.

To request additional support for this connector or to request support for other devices, please contact support@network-perception.com.

Connectors + Samba (SMB) Access Error

+

This error can be caused by two communication scenarios between Linux and Window. Either SMB encryption is enabled on the Server or SPN target name validation level is enabled (or both). To check which of these features is causing the issue, Run PowerShell on the Windows Server as administrator and run the following command:

Get-SmbServerConfiguration

If EncryptData = True, it can be disabled using:

Set-SmbServerConfiguration -EncryptData 0

If SmbServerNameHardeningLevel is set to any value other than the default of 0 run:

Set-SmbServerConfiguration -SmbServerNameHardeningLevel 0

to restore the default.

Connectors fails to initiate connection to outside devices

+

In some instances, the Linux distribution is preventing the connectors (Docker) from initiating connections to outside devices. The solution is to update the firewall settings on the Linux distribution using the following commands:

# firewall-cmd --zone=public --add-masquerade --permanent
# firewall-cmd --reload
# systemctl restart docker

Configuring Read-only Access to Cisco

+

The NP-View Connector for Cisco uses a read-only SSH connection to collect the output of the show running-config command. It is best practice to create a dedicated read-only user on your Cisco devices when configuring connectors. Here are the commands to only give the minimum permissions needed for this user:

conf t
aaa authorization command LOCAL
privilege show level 2 mode exec command running-config
privilege cmd level 2 mode exec command terminal
username $USERNAME password $PASSWORD priv 2
end

Bulks Start Parameters

+

To help balance the processing load of managing multiple connectors and improve user experience on the topology map, the bulk start function can be scheduled to off hours using system parameters. The docker-compose.yml file contains two parameters for the bulk system start function in the monitor: environment: section

  • connBulkStartTime=21:00:00 # defines the start time for the connectors, format is Hours:Minutes:Seconds, 24 hour clock.
  • connBulkStartSpread=00:15:00 # defines the connector start stagger, format is Hours:Minutes:Seconds

Deleting Connectors

+

Connectors can be deleted by entering the connector group name and passphrase to gain access to the connector. The connector can be deleted by selecting the trash can in the upper right corner.

If the passphrase is forgotten, the connector can be forcefully deleted by the Linux Admin by removing the connector file from the folder

/var/lib/docker/volumes/NP-Live_np-connect/_data.

Help Center

Help Center

The Help Center can be found on the system menu on the upper right corner of the topology.

The Help Center will display warnings or errors identified during the import of device files.

The information in the help center is designed to provide information for the tech support team to help diagnose the issues.

There are many types of possible errors including:

  1. Invalid file formats (e.g., .gif or .png)
  2. Improperly formatted files (files exported as text but loaded into a word processors where extra characters are added before saving).
  3. Incomplete set of files (many devices require more than one file for import this includes Palo Alto and IP tables)
  4. Misconfigured files where rules or objects are undefined.

As every customer has a different environment and possible device configurations are endless.  We sometimes run into a situation where the parser cannot handle the device as configured.  When this happens, we request the customer to sanitize the config file on the NP Poral and upload the file for debug purposes.  Support from our customers is important for us to quickly remediate parsing issues unique to a device or specific file.

The Help Center provides a download for the error log which can be submitted to technical support through the support portal.
