First off, don't use 1 over True in while loops. While 1 works, using True is much clearer.
Secondly, you have inconsistent indentation. While in Python 2.x, this doesn't affect much, Python 3.x will throw an error.
Never use try-except without a specific error to catch. There could easily be an error that goes un-noticed. 
Most of your names are okay, but there are some like c, or e that should be clearer. Variable and function names should also be in snake_case, and classes should be in PascalCase. Names like conn should be renamed to something else, like connection, for example.
You need more blank lines. There should be two blank lines in between each code block/function/class on the top level.
Finally, you should avoid wildcard imports like this: from thread import *. You should either import the entire module, or any classes/functions/variables that you need.
