You’ll find that your Linux distribution has compiled some defaults that may not be suitable to this application, but they are *not* hard coded.

if you run ‘sysctl -a’ you’ll find more parameters that can be tweaked in realtime than you’ll want to ever know about. Try grepping (flitering) that list for just tcp parameters that may be suitable by doing the following at a command line on Linux…

	sysctl -a | grep tcp

To set one (as an example, not saying this is what you need for your application) as the root user…

	sysctl net.ipv4.tcp_keepalive_intvl = 75

And if you want to make that permanent, each time you reboot the Linux machine, most distributions allow you to add this to the file in /etc/sysctl.conf, e.g. for the above, just add…

	net.ipv4.tcp_keepalive_intvl = 75

… to the end of the file.
