Operating Systems Linux Red Hat SSH connection drops in 5 minutes Post 302673891 by Corona688 on Wednesday 18th of July 2012 01:58:19 PM

Drops even when busy, or only when idle?

Putting settings into /proc/ for keepalives isn't too great an idea since it will apply to all your connections, even ones which don't need it, increasing your bandwidth a lot. Getting the right combination of settings to do what you actually want can be tricky, too.

I usually use libkeepalive when I need to connect to something with obnoxious timeouts. It can be applied to a single program, works for anything(intercepting socket calls to impose default keepalive settings when a program creates a TCP socket) and is relatively easy to configure.
