Paramiko and Pseudo-tty Allocation?

I think you want the invoke_shell method of the SSHClient object (I'd love to give a URL but the paramiko docs at lag. Net are frame-heavy and just won't show me a specific URL for a given spot in the docs) -- it gives you a Channel on which you can do exec_command and the like, but does that through a pseudo-terminal (complete with terminal type and numbers of rows and columns! -) which seems to be what you're asking for.

I tried this and it didn't work. Am I doing it wrong? My script: #!

/bin/env python from __future__ import print_function import paramiko ssh = paramiko.SSHClient() ssh. Set_missing_host_key_policy(paramiko.AutoAddPolicy()) ssh. Connect('hostname', username='root', password='rootpw') chan = ssh.

Invoke_shell() stdin, stdout, stderr = chan. Exec_command('tty') print(stdout.readlines()) The traceback: In 1: %run debugterm. Py --------------------------------------------------------------------------- SSHException Traceback (most recent call last) /some/long/path/debugterm.Py in () 6 ssh.

Connect('hostname', username='root', password='rootpw') 7 chan = ssh. Invoke_shell() ----> 8 stdin, stdout, stderr = chan. Exec_command('tty') 9 print(stdout.readlines()) 10 /usr/lib/python2.6/site-packages/paramiko/channel.

Pyc in exec_command(self, command) 211 self. _event_pending() 212 self.transport. _send_user_message(m) --> 213 self.

Looks like David's code works on my system. Thanks David. – goozbach Oct 4 at 20:05.

The following code works for me: #! /usr/bin/env python import paramiko ssh = paramiko.SSHClient() ssh. Set_missing_host_key_policy(paramiko.AutoAddPolicy()) ssh.

Connect('localhost',username='root',password='secret') chan = ssh. Get_transport(). Open_session() chan.

Get_pty() chan. Exec_command('tty') print(chan. Recv(1024)) This was just assembled from looking at a few examples online... not sure if its the "right" way.

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.
