Assuming you are on Linux, you can run #man tcp
and take a look at the tunable parameters that control TCP protocol timeouts: tcp_keepalive_intvl tcp_keepalive_probes tcp_keepalive_time They can be tuned via /proc filesystem. These changes are system-wide, so you should consider the performance of other applications on this system with those changes. > -----Original Message----- > From: twisted-python-boun...@twistedmatrix.com [mailto:twisted-python- > boun...@twistedmatrix.com] On Behalf Of gary clark > Sent: Tuesday, February 16, 2010 10:19 AM > To: Twisted general discussion > Subject: Re: [Twisted-Python] Pulling the ethernet cable out > > Hey Alvin, > > In the document link you provided the packets are being sent periodically > every 2 hours for setTcpKeepAlive(1).
