Hello, Reciently i wrote a simple client using Reconnecting Factory. That client logins to my socket server.. and that`s it. Interesting thing is that it is seems that twisted client, sends some ping on a TCP level without sending any data to the socket directly. Because when i pull out cord from the ethernet card simulating network falure, client in about 10-15 seconds determines that connection lost!! (pretty cool) While my server still thinks that client is up. I am using SO_KEEPALIVE on server - but documentations says it will only ping (and so timed outed) on a few hours. How do i make my server act the same way as the client? (to make some sort of a low level cheching of connections is broken without actualy sending anything to socket) -- Best regards, Norman mailto:NormanTindall@zdisk.net
