I haven't done anything like that as I don't use Windows for anything serious.  But I see basically no problem, as at least some of the packages you've mentioned are portable to marginal OSes like Windows *g*
So my tip would be, start implementing, I personally would probably stick to conch for many concurrent sessions, and come back (or use the twisted list) when you encounter troubles.

Betreff: [Tutor] Python on Windows with SSH for Cisco devices
Von: "Chris Hallman" <challman at gmail.com>

Has anyone successfully used Python on Windows with SSH connections to Cisco
devices?  I'm referring to using a Python module (Paramiko, pyssh though not
actively developed, Twisted.conch, etc.)  and not shelling out via Pexpect
(doesn't work on Windows) or Plink.  I need to connect to hundreds of Cisco
routers/switches so that I can run numerous commands to gather data.  Here is
a snippet of my Telnet commands that I need working via SSH:
self.tn.write("wr\n")
(index, match, read) = self.tn.expect(["OK"], 15)
if not match:
self.tn.write("yes\n")
time.sleep(random.uniform(0,2))
self.tn.write("copy tf runn\n")
self.tn.read_until("host []?",  7)
time.sleep(random.uniform(0,2))
self.tn.write("192.168.136.51\n")
self.tn.read_until("filename []?",  7)
time.sleep(random.uniform(0,2))
self.tn.write(self.filename +"\n")
time.sleep(random.uniform(0,2))
self.tn.read_until("[running-config]?",  7)
time.sleep(random.uniform(0,2))
self.tn.write("\n")
I've been able to get the following to work, but the TCP connection closes
after each command:
import paramiko
client = paramiko. SSHClient()
# ignore host keys for the test
client.set_missing_host_key_policy(paramiko. MissingHostKeyPolicy())
client.connect('host####', 22, 'user####', 'passw####')
(stdin, stdout, stderr) = client.exec_command('sh ver | i IOS')
print stdout.read()
I've read that I can use a dummy channel (not sure the difference between a
channel and a TCP connection) to keep the connection active.  I've read the
docs and I've searched the net, but I can't seem to find a good example that
helps.  Programming isn't my day job so I'm not that great at it.  Any help
would be great. 
Thanks!
