问题
I successfully managed to connect to a Cisco IE-2000-L switch via SSH. I used the Renci SSH.NET library.
Starting guide: http://vwiki.co.uk/SSH_Client_(PowerShell)
My working code is
# Load SSH library (for .NET 4.0 and PowerShell 3)
$DllPath = "D:\temp\Renci.SshNet.dll"
[void][reflection.assembly]::LoadFrom( (Resolve-Path $DllPath) )
# Connect to switch (Cisco IE2000-L) with IP, port, username, password
$SshClient = New-Object Renci.SshNet.SshClient('172.20.91.30', 22, 'admin', 'mypassword')
$SshClient.Connect()
# execute one command on Cisco switch
$SshCommand = $SshClient.RunCommand('show arp')
# show result
$SshCommand.Result
# close SSH connection
$SshCommand.Dispose()
$SshClient.Disconnect()
$SshClient.Dispose()
My problem is
The above code sends just one command. But I want to execute several commands consecutively without closing and reopening a session.
If I add a second command right after the first one
# execute one command on Cisco switch
$SshCommand = $SshClient.RunCommand('show arp')
$SshCommand = $SshClient.RunCommand('show start')
...the script hangs and never finishes. What am I doing wrong?
Minor relevant information
- My main goal is to send multiple commands at once to a Cisco switch
- I already tried Plink together with batch cmd input. It's not reliable enough. It works sometimes and sometimes not.
- I already tried telnet scripting. Too awkward.
