Hi everyone...I'm new to ruby and I'm looking for some good manual about  
TCP networking in Ruby. I've
a Programming Ruby book, but it doesn't contain enough informations I  
want. I've googled the web but
didn't see any full manual yet. I want to know such informations like for  
example: how to check in
my code, when the connection was closed by a foreign host etc.



Regards
Jacek
