Some python ssh packages are available if you are wanting to execute
commands on a machine that has ssh. ssh servers are available for
windows, but they aren't necessarily so well supported.
Here's a simple approach that works on ssh servers:
import commands
hostname = commands.getoutput('ssh [EMAIL PROTECTED] hostname')
print hostname
Alternatively, you could run a Python-based web server from a simple
script like the one below, allowing you to execute a few commands
anonymously. This is the sort of thing you might and to do on LANs for
a windows computer you don't want to run SSH on.
"""
This is a small Web server that will allow remote clients to run
commands on this server and get the output.
Usage: python <thisscript>
Client Usage:
lynx http://localhost:8000/hostname
On Windows this can be installed as a service with WinServ: winserv
install py_http_serv C:\Python23\python.exe C:\_admin\httpd_monitor.py
- make sure that this service is set to restart the process if it fails
Things I could improve: I could have it download a new dict of commands
which would have to be GPG signed.
- I could add a feature that would allow it to give me it's public gpg
key...and I could encrypt messages for it.
Perhaps I could even have it push out a shell of some sort.
