The timeout for TCP keep-alives messages can be found in
/proc/sys/net/ipv4/tcp_keepalive_time
To disable it for telnet, see man telnetd:
-n Disable TCP keep-alives. Normally telnetd enables the TCP
keep-alive mechanism to probe connections that have been
idle for some period of time to determine if the
client is still there, so that idle connections from
machines that have crashed or can no longer be reached may
be cleaned up.
