Sorry for the poor info on my part Steven et al. I did not do my homework.
I thought that sshclient was an imported module, however it is pxssh that I am importing as sshClient. import pxssh as sshClient There is no particular reason I need to debug this using the debugger to troubleshoot this. I was just using it to step through the program at the time. Thank you eryksun for the help…especially the quick response and great explanation. Both of your suggestions will work for me, particularly the 2nd one. I am not actually using “str” for the reasons you described. I just renamed it when I emailed my question, which was probably not a good idea.

The pxssh object should have the methods read, read_nonblocking, readline, and readlines. But you probably want the output from between prompts. The prompt() method calls expect() to match the custom prompt, and returns False if there's a timeout (the default is 20 seconds). This sets the instance attribute "before" with the text that came before the match: ssh.sendline('ls /var/tmp') if ssh.prompt(): output = ssh.before Alternatively, if you've setup a public key on the host via ssh-keygen, you could use subprocess.check_output() instead: import subprocess cmd = ['ssh', '-l', login, hostname, 'ls /var/tmp'] output = subprocess.check_output(cmd)
