SCO Unix TCP/IP and NFS FAQ

This article is from a FAQ concerning SCO operating systems. While some of the information may be applicable to any OS, or any Unix or Linux OS, it may be specific to SCO Xenix, Open There is lots of Linux, Mac OS X and general Unix info elsewhere on this site: Search this site is the best way to find anything.

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

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.

But see Keep in touch (tcp keepalives etc.) for a more generic look at network timeouts.

Got something to add? Send me email.

Using XP Pro:
When I mis-type my pw in Tiny term it locks me out for 2 minutes - how do I change that "time_wait" period so I can re-enter the pw immediately?

That's absolutely nothing to do with tcp/ip. That's password policies.

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

Actually, you can do this "on the fly" with the command inconfig tcp_2msl <value>, where <value> is some integer between 1 and 65,535 inclusive. /etc/default/inet will be updated and the running kernel will be changed without having to restart TCP services.
