I *think* from what you're saying you want to use something like mt_interact.
I only noticed this myself when reviewing the docs. Here's a quick and crude
bit of demo code that replaces mt_interact with your own version:
import telnetlib as tl
rude_words = ['perl', 'microsoft']
class myTelnet (tl.Telnet):
def my_interact (self):
"""Multithreaded version of interact()."""
line = sys.stdin.readline()
if not line:
for rw in rude_words:
if line.find (rw) != -1:
print "Tsk tsk you know you can't say things like that in public"
con = myTelnet (sys.argv)
This was cribbed directly from the source. Obviously what you could do here
is replace the while loop with your own checking.
