How do you change the MTU/MRU window size for SCO OpenServer
5.0.5/6 on a TCP/IP ethernet connection? I need to change it to
improve performance on my satellite VPN.

Thanks in advance,
Justin

ifconfig for the MTU/MRU. However, you may also wanna tweak the
deault receive window size to the 64K maximum for high latency
satellite performance. For that, see "inconfig" which tweaks settings
in /etc/default/inet. I once scribbled some articles in the past on
the subject:

He might also want to read RFC 2488
