instead of:
except error:
response=3D
maybe try:
except Exception, e:
response =3D e

Sometime around Fri, May 09, 2003 at 01:49:01AM -0400, noc waltzed in like =
he freakin' owned the joint and start spouting off about:
> I'm working on a new script.
>=20
> I'm reading a file that contains a list of hosts, user ids, and passwords.
> It's getting parsed into a list of lists like so:
> [[host, userid, password],[host, userid, password],...]
>=20
> Now I'm telnetting to each host, and issuing some commands, and returning
> the data:
>=20
> def nfscheck(entry):
> try:
> tn=3Dtelnetlib.Telnet(entry[0])
> except error:
> response=3D
> else:
> tn.read_until('login: ','15')
> tn.write(entry[1]+'\n')
> tn.read_until('Password: ','15')
> tn.write(entry[2]+'\n')
> tn.read_until('$','15')
> tn.write('ls\n')
> response=3Dtn.read_until('$','15')
> tn.write('exit\n')
> finally:
> return response
>=20
> Now, sometimes these hosts are down for whatever reason, or maybe the list
> isn't up to date, so I get:
>=20
> File "C:\Python22\lib\telnetlib.py", line 190, in __init__
> self.open(host, port)
> File "C:\Python22\lib\telnetlib.py", line 219, in open
> raise socket.error, msg
> error: (10060, 'Operation timed out')
>=20
> I realize that in the last line, I have to use 'error' as the name for the
> except statement, but how do assign 'Operation timed out' to my response
> variable?
