Python ssh using Tor proxy

paramiko, python, ssh, tor

Solution

You need to create `ProxyCommand` (a socket-like object) and pass it to `client.connect()`

import paramiko

conf = paramiko.SSHConfig()
conf.parse(open('/home/user/.ssh/config'))
host = conf.lookup('host')
print host

proxy = paramiko.ProxyCommand(host['proxycommand'])

client = paramiko.SSHClient()
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
client.connect(host["hostname"], username=host["user"], password='test', sock=proxy)
client.close()

Docs for `connect()` method. Note `timeout` parameter. It's always a good idea to specify it if you are doing some automation.

Problem

I would like to be able to send data through Tor when I use ssh from Python scripts. Tor works as expected when I use an OpenSSH client to manually ssh to the host. This is my ssh config file. I use connect-proxy with ProxyCommand to route the connections through Tor (again, this works fine via a standard OpenSSH client): ``` host host user user hostname host.domain.com CheckHostIP no Compression yes Protocol 2 ProxyCommand connect-proxy -S localhost:9050 %h %p ``` I have this Python test script: ``` import paraproxy import paramiko conf = paramiko.SSHConfig() conf.parse(open('/home/user/.ssh/config')) host = conf.lookup('host') print host client = paramiko.SSHClient() client.set_missing_host_key_policy(paramiko.AutoAddPolicy()) client.connect(host["hostname"], username=host["user"], password='test') client.close() ``` This script does ssh to the host, however, it does not use the ProxyCommand in the ssh config file, thus it does not route traffic through Tor. I've tried a few different configurations, but I cannot make it work. Any ideas on how to make this work?
