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

Hi Lucas,

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

Hope that helps

Hi Lukas,

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

Source Code:

   Break;
}
#'------------------------------------------------------------------------------
#'Format the command output if the command result was sucessfull.

If($output.results."cli-result-value" -eq 1){
   [Array]$lines = $output.results."cli-output".Trim().Split("`n")
   ForEach($line In $lines){
