Reduce idle connection timeout

Reduce idle connection timeout

[Márcio Oliveira]

Hi,

   Anybody knows how can I reduce the idle connections (TCP, UDP, ...) 
timeout in Linux systems?

Thanks in advance!

Well UDP doesn't have a timeout because it's connectionless, but
TCP (stream sockets) do. Look in /proc/sys/net/ipv4 and see if you
can find what you want. You probably are looking for tcp_fin_timeout
if you are concerned about what `netstat -c` shows after a disconnection.
FYI, If you are just trying to reuse an address, you don't have
to muck with kernel parameters, just `man setsockopt` SO_REUSEADDR, etc.

TCP timeout minimums are specified in the standard and we follow them
anyway. UDP has no "connection".
