Can't pass command in a menu
Hi, I'm working on the Cisco ISE (a network access control equipement), and i'm trying to generate a report via SSH.
i'm using this powershell script
Import-Module Posh-SSH
$password = ConvertTo-SecureString "PSSWR" -AsPlainText -Force
$credential = New-Object PSCredential ("USER", $password)
New-SSHSession -ComputerName "SERVER" -Credential $credential -AcceptKey -Verbose
$sw_ssh = Get-SSHSession -Index 0
$stream = $sw_ssh.Session.CreateShellStream("dumb", 0, 0, 0, 0, 1000)
$stream.Write("application configure ise`n")
$stream.Write("0`n")
$Response = $stream.Read()
$stream.Write("exit`n")
Remove-SSHSession -Index 0 | Out-Null
Write-Output $Response
the thing is after the application configure command this menu is prompt :
SERVER/@User# application configure ise
Selection configuration option
[1]Reset M&T Session Database
[2]Rebuild M&T Unusable Indexes
[3]Purge M&T Operational Data
[4]Reset M&T Database

[20]Reset Context Visibility
[21]Synchronize Context Visibility With Database
[22]Generate Heap Dump

[24]Force Backup Cancellation
[25]CleanUp ESR 5921 IOS Crash Info Files
[26]Configure TCP params
[27]Recreate undotablespace
[28]Fetch SGA/PGA Memory usage
[0]Exit
And the script can't pass this menu, no error and no crash it's just blocked after the menu and wait for the Remove-SSHSession
Are you sending carrige returns after each command? I see the n but not the backtick before it

When i send the 3 commands i use the same syntax :
$stream.Write("application configure ise`n")
with the `n at the end.
I just saw if you look at my post via Email the "backtick" doesn't show up, but they are here !
When you read back the stream is there a menu refresh or the command at the end of the menu? Dont have any networking kit to test

As you can see the "0" command is not even pushed. (i added some sleep and moved the $Response = $stream.Read())
Sadly no way to replicate on my end, only thing I can say would be to change the the sleep for a stream read and check that the string for the menu is present to be sure its not a timing issue. But outside of that no clue.
I didn't think of reading the stream and add a condition, do you have any exemple of code that i can replicate and try this solution ?
Check the code from the invoke-sshshellstreamcommand function
