Powershell Toolkit 4.6 & Invoke-NaSsh

LUKASPRELOVSKY

Hello,

 

I'm running a powershell script to collect some ifgrp informations from my 7-mode filers (powershell via putty).

 

 $IfGrpStatus = Invoke-NaSsh "ifgrp status $($ifgrp)"

How I can close current sessions, which were opened by my script?
The Problem is, after I start my script I can't login to my filer:

 

/sbin/ngsh: Too many users
Connection to XXXXXX closed.

 

Everytime I have to disconned all sessions with ssh FILER logout telnet command and that's not comfortable for my usage.

 

Thank you and regards,

Lukas

Best Regards,
Lukas

Hi Lukas,

 

Here is an "example" for you to modify to meet the requirements of your environment.

Hi Lucas,

 

You could try to use "Invoke-NaSystemApi" instead of "Invoke-NaSsh". I've posted some powershell examples here:
