reconfig tcp_fin_timeout will affect other server application?


Just want to know if I'm going to reconfigure the tcp_fin_timeout in our server, will it affect other server application on our server? for example changing 60secs to 30secs. What are the consequences? I'm sorry, not yet very familiar using Linux. Thanks

a) it shouldn't really make much difference under most circumstances

b) if this is a production server, do NOT even THINK about making any changes like this unless you are CERTAIN you know what you're doing, and prepared to invest effort thoroughly testing your application in a QC environment first

c) if you're interested in what it means, read up "TCP state machine", or buy a copy of the late W/ Richard Stevens "TCP/IP Illustrated" (a brilliant series, by the way! Highly recommended!):

'Hope that helps .. PSM

Thanks. The main problem is that, the server is having lots of TIME-WAIT for a single client.

That just means that you're opening and closing lots of short connections in rapid succession.
