<p class="MsoPlainText">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:<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText"> ssh.sendline('ls /var/tmp')<o:p></o:p></p>
<p class="MsoPlainText"> if ssh.prompt():<o:p></o:p></p>
<p class="MsoPlainText"> output = ssh.before<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">Alternatively, if you've setup a public key on the host via ssh-keygen, you could use subprocess.check_output() instead:<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText"> import subprocess<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText"> cmd = ['ssh', '-l', login, hostname, 'ls /var/tmp']<o:p></o:p></p>
<p class="MsoPlainText"> output = subprocess.check_output(cmd)<o:p></o:p></p>
