- 2018 Jan 4 – For Configuration Extractor, Sirius’ Mark Scott added code to browse to open and save files. Added kcdaccounts to extraction.
- 2018 Jan 3 – new Powershell-based NetScaler Configuration Extractor script
NetScaler Configuration Extractor
New and improved NetScaler Configuration Extractor. This time using PowerShell. Here are some features of the script:
- Given a ns.conf file, the script extracts CLI commands for one or more Virtual Servers.
- Given a Virtual Server name, the script enumerates all objects linked to the Virtual Server (e.g. Responder Policies) and provides their configuration too.
- Finds global settings that might affect the operation of the chosen Virtual Servers.
- The CLI output is listed in proper order. For example, create monitors before binding them to Service Groups.
- If an exact Virtual Server name is not specified in the script, then the script will prompt you to select one or more Virtual Servers. The list of Virtual Servers can be filtered.
The extracted Virtual Server CLI configuration can be used for documentation, or to apply the configuration to a different appliance.
I originally attempted a dynamic extraction using complicated regular expressions, but there wasn’t enough control over the extraction and output process. The new PowerShell script explicitly enumerates specific objects, thus providing complete control over the output. For example, before binding a cipher group to a Virtual Server, the current ciphers must first be removed.
The script uses several techniques to avoid false positive matches, primarily substring matches.
Let me know what bugs you encounter.
Configure NetScaler from PowerShell
You can use any scripting language that supports REST calls. This section is based on PowerShell 3 and its Invoke-RestMethod cmdlet.
Brandon Olin published a PowerShell module for NetScaler at Github. 💡
CTP Esther Barthel maintains a PowerShell module for NetScaler at https://github.com/cognitionIT/PS-NITRO. See Citrix Synergy TV – SYN325 – Automating NetScaler: talking NITRO with PowerShell for an overview.
The below NetScalerPowerShell.zip contains PowerShell functions that use REST calls to configure a NetScaler appliance. It only takes a few seconds to wipe a NetScaler and configure it with almost everything detailed on this site. A glaring omission is file operations including licenses, certificate files, and customized monitor scripts and the PowerShell script assumes these files are already present on the appliance.
Most of the functions should work on 10.5 and 11.0 with a few obvious exceptions like RDP Proxy. Here are some other differences between 10.5 and 11.0:
- PUT operations in NetScaler 11 do not need an entity name in the URL; however 10.5 does require entity names in every PUT URL.
- https URL for REST calls works without issue in NetScaler 11, but NetScaler 10.5 had inconsistent errors. http works without issue in NetScaler 10.5.
Nitro REST API Documentation
NetScaler Nitro REST API documentation can be found on any NetScaler by clicking the Downloads tab. The documentation is updated whenever you upgrade your firmware.
Look for the Nitro API Documentation.
Extract the files, and then launch index.html.
Start by reading the Getting Started Guide, and then expand the Configuration node to see detailed documentation for every REST call.
The Nitro API is also documented at REST Web Services at Citrix Docs.
