Hi,
I need to run a remote program from a server that I have access rights
to. I want to be able to do this from within in my python script and I
want to use ssh (or anything else that will work). However, doing
something like:
ssh -l user host "/path/to/program"
prompts for a password and I don't know how to supply one via a python
script. Is there an easy way out? Can I log onto to the other machine
via ssh somehow? Does a python script support this? Thanks!

Steve,
You don't say if you are running on Windows or not but this is a ssh
wrapper I use that uses the pexpect library...:
import pexpect
import sys
import re
import os
PROMPT = "\$|\%|\>"
class SSH:
def __init__(self, user, password, host):
self.child = pexpect.spawn("ssh %s@%s"%(user, host))
i = self.child.expect(['assword:', r"yes/no"], timeout=120)
if i==0:
self.child.sendline(password)
elif i==1:
self.child.sendline("yes")
self.child.expect("assword:", timeout=120)
self.child.sendline(password)
self.child.expect(PROMPT)
def command(self, command):
"""send a command and return the response"""
self.child.sendline(command)
self.child.expect(PROMPT)
response = self.child.before
return response
def close(self):
"""close the connection"""
self.child.close()
if __name__=="__main__":
import getpass
password = getpass.getpass("Password: ")
ssh = SSH("RemoteUsername", password, "RemoteHost")
print ssh.command("pwd")
ssh.close()
