A Q About Half Open TCP Connections
« on: May 31, 2005, 11:09:12 PM »

Hi!

Windows users shall know that after SP2, half-open TCP Connections that a program can make at most, is bounded by 10. This resulted in slow DL's on most P2P programs. To solve this problem, a patch is released. Anyway, my question is about linux. I'm running FC3 and I suspected, with aMule such a problem I have. Are there anybody among you to know if there is such a limitation in Linux and if there is, how can I increase this limit?

Note: This question is I think relevant but not directly about aMule. So I post the message here. If I'm wrong, excuse em  :rolleyes:

For conntrack exists a limit. In general I could imagine that there is something similar.

well in linux the limit is set in some kernel parameter, you might want to google for it ;)
but its way over 1000 connections, so I doubt that your slow dl has anything todo with that....
check out the http://wiki.amule.org page for some infos on -> why is amule slow

and maybe you will find some more infos there

Linux have almost every parameters configurable thru /proc/ interface. Take a look to http://ipsysctl-tutorial.frozentux.net/
