dynamically set up ssh -r & paramiko?


Hello, I'm trying to write a script which will allow me to initiate (spawn?)
an SSH reverse tunnel from an internal box (inside a firewall) to an
external box, while logged into the external box.

I posted to another list and was pointed in the direction of paramiko. I've
read the tutorials, but cannot seem to figure out exactly how I can do
this... I'm hoping someone can look at what I'm trying to do below and
provide an example...

#!/usr/bin/python

import os, time, subprocess
REMOTE_HOME='/my/remote/mount' #mounted drive to REMOTE_HOME from
LOCAL_MACHINE

cmd = 'while true; do ssh -R 8022:localhost: 22 MyUserName@Remo teHost ; sleep
60; done'
while 1:
while os.path.exists( os.path.join(RE MOTE_HOME,'mySe cretFile'):
proc= subprocess.call (cmd,shell='Tru e')

if proc: os.kill(proc.pi d)

if os.path.exists( os.path.join(RE MOTE_HOME,'Kill Script'):
break

--

Note, I know the reverse tunnel script works on it's own run from the shell,
but I don't want to leave it open always... furthermore it seems to be a
rather 'brute force' method. It seems paramiko might provide a more elegant
solution! Does anyone have any ideas on how to make this work?

Thanks,
john

Hello, I'm using paramiko 0.9 to access one of my home machines and then execute a command. But with the script included below, the command gets executed on the 2nd to 6th go, never on the first. And the commands aren't that commplicated, they are usualy 'touch some-file' or 'cp some_file to /tmp/a'. Am I misunderstanding the paramiko's API or ... ?

As more and more python packages are starting to use the bloomy (Java-ish) 'logging' module in a mood of responsibility and as I am not overly happy with the current "thickener" style of usage, I want to put this comment and a alternative most simple default framework for discussion.

Hello all, I developed a solution using paramiko and a similar Telnetlib class to access a several number of network devices in replacement of using Pexpect library and openssh client. It worked so well but the bad performance made me think in how to improve Paramiko. Is there some way to do that, for example using some C extension or even other library? I would like to continue using Paramiko, but in production environment it could...

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

For most users, this new feature is actually very convenient. If you want to control the update process,...
