How can paramiko get ssh command return code?

SSHClient is a simple wrapper class around the more lower-level functionality in Paramiko. The API documentation lists a recv_exit_status() method on the Channel class A very simple demonstration script: $ cat sshtest. Py import paramiko import getpass pw = getpass.getpass() client = paramiko.SSHClient() client.

Set_missing_host_key_policy(paramiko.WarningPolicy()) client. Connect('127.0.0.1', password=pw) while True: cmd = raw_input("Command to run: ") if cmd == "": break chan = client. Get_transport().

Open_session() print "running '%s'" % cmd chan. Exec_command(cmd) print "exit status: %s" % chan. Recv_exit_status() client.close() $ python sshtest.Py Password: Command to run: true running 'true' exit status: 0 Command to run: false running 'false' exit status: 1 Command to run: $.

Really appreciate for your answer! I've use it in my project. Thank you very much.So far I can use paramiko instead of wrapping system command ssh in programming with python.

– Beyonder Aug 25 '10 at 10:11 It's only something I put together by looking at the source of SSHClient, so it might not be optimal. BTW: if this does what you want, you might want to "accept" my answer. – JanC Aug 25 '10 at 15:58.

Paramiko can't see more than you would see in a normal SSH session, so you see no exit codes by default. Solution: you have to change your command to make it return the exit code. Command | echo $?

Should work fine on Bash. Client = paramiko.SSHClient() stdin, stdout, stderr = client. Exec_command(command + '| echo $?').

Use Net::SSH::Perl; ( $cmdout, $cmderr, $cmdexit ) = $ssh->cmd($command) – Beyonder Aug 25 '10 at 2:57 It seems that I was wrong.Sorry. – leoluk Aug 25 '10 at 14:21 leoluk, -1 for you because JanC has better (and right) answer. – Jeffrey Jose Dec 29 '10 at 8:38 1 I disagree.

I'm running into an error where the remote server won't return exit codes, no matter what I do, for an scp push.So echo-ing the exit code is actually the best solution. – decoy Sep 22 at 17:51.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
