Setting the Linux keepalive option
Chapter 3 of the GS/S System Administration Guide under the section
entitled "Disrupted Communications" provides information on configuring
the network protocol keepalive option under various platforms.
On Linux, this option is set to 2 hours (7200 seconds) by default.
If you wish to change this setting, execute:
unix> /sbin/sysctl -w net.ipv4.tcp_keepalive_time=XXXX
where XXXX is the new value in seconds. You can also manually edit the
system configuration file /etc/sysctl.conf and add the line:
net.ipv4.tcp_keepalive_time=XXXX
