Good evening all, I'm trying to script control of a network device. I have it working okay with Net::Telnet, but I really need to script this with SSH. Unfortunately the device has a very rudimentary implementation of SSH. I can login, but fail rather quickly with the error "Channel open failure: 1: reason 4: Server supports one session per SSH client"

It's my first try with Net::SSH::Perl, and at this point all the script does is issue a $ssh->login and attempts to send a command with $ssh->cmd

I've looked through the various module docs and didn't see anything that looked hopeful in restricting the number of concurrent "sessions". Here is a debug log of the failure. Am I using the right perl module for the task? Any suggestions on how to restrict to a single session?

The device I'm trying to access has a very irregular command structure with varying prompts, some asynchronous messages, so the eventual script becomes pretty complex. 

admin1@10.2.56.13's password:
myhost: Login completed, opening dummy shell channel.
myhost: channel 0: new [client-session]
myhost: Requesting channel_open for channel 0.
myhost: channel 0: open confirm rwindow 1000 rmax 1000
myhost: Got channel open confirmation, requesting shell.
myhost: Requesting service shell on channel 0.
myhost: channel 1: new [client-session]
myhost: Requesting channel_open for channel 1.
myhost: Entering interactive session.
myhost: Channel open failure: 1: reason 4: Server supports one session
