Execute Commands on Remote Computers over Network

[dylpkls91]

I have been researching this topic and come up with some code to make
it work. It uses SSL and requires the 3rd party package Paramiko (which
requires PyCrypto). However, at this moment I have no network to test
the code on! Trying to connect to localhost (127.0.0.1) fails. Before I
buy network components, I want to be sure that this code will work.
Will someone with two networked computers try it out for me? Thanks!
Code:

def remotely_execut e_command(ipadd r, port, user, passwd=None, cmd):
import paramiko
transport = paramiko.Transp ort(ipaddr + ":" + port)
transport.conne ct(username=use r, password=passwd )
channel = transport.open_ session()
channel.exec_co mmand(cmd)
print "Command " + cmd + " executed by user " + user + " with
password " + passwd + " at " + host + ":" + port

Why not just spawn an invocation of SSH?

@Dennis: yes, I know, but I wasn't thinking, and it doesn't solve the
problem.

@Lawrence: I'm sorry, but I'm a newbie. Can you explain what this
means, and how I could do it in Python? Thank you very much.

SSH is the standard means of remotely executing commands on one *nix
system from another <http://www.openssh.com/>. It is included with all
self-respecting *nix systems these days. You can set up a trust
relationship between particular accounts on two systems, so one can
connect to the other without a password. All communication is encrypted
to lock out eavesdroppers.

Also note that Cygwin gives you openssh in a Unix-shell-like
environment. Has its own Python too, though you don't do things in
Cygwin for performance, usually.

I'm sorry, I should have clarified. I want to execute commands on
networked computers running <i>Windows XP</i>. Thank you for you
concern anyway. Does this mean that the Paramiko module only works on
Unix systems?

Where is the code that is supposed to receive this connection? There
has to be something running on the target PC to accept incoming
commands. Paramiko appears to use SSH, which (as far as I know)
connects to a computer running an sshd program or equivalent and
executes commands via that program. If there's no sshd running on the
target, you can't do anything.

Thanks for the clarification. Can I get 'sshd' or an equivalent for
Windows?

Thank you all for your responses.

I have managed to figure out a solution using XML RPC which fits my
needs perfectly.

BTW, if you want to test networking between two machines on one single
(Windows) computer, try VirtualPC. (Free from MS.)
