SCO Telnet Keepalive, Children wont close

[muxdata]

I have changed the default keepalives on telnetd as follows:
telnetd -h -k 300 -K 60 -N 5
When the timeouts are reached, the telnetd session closes but none of the children close. This leaves hundreds of unattached processes. Particularly annoying when some of the processes are locking the database.
SCO Openserver version 5.0.5.

I see in netstat that processes get stuck in TIME_WAIT for a long time. How can I change this behaviour?

For some reason, OpenServer sets that to 30 minutes even while stating that the recommended setting is 4 minutes!

You can edit /etc/default/inet and change tcp_2msl to lower the time. Stop and restart tcp/ip or reboot.
