reconfig tcp_fin_timeout will affect other server application?

chi_lazaro · 07-29-2010, 08:37 AM

Just want to know if I'm going to reconfigure the tcp_fin_timeout is there any effect to the other applications? or will affect some applications? for example changing 60secs to 30secs, 30secs to 15secs. What are the consequences? I'm sorry, not yet very familiar using Linux. Thanks

Changing this will reduce greatly the number of TIME_WAIT (that you can see with netstat)

I've did that on one of our firewall that was a bit hammered by requests.
I've reduced it to 10 then 5.
Now it's working like a charm.
