UNIX for Dummies Questions & Answers

Hi,

I have inherited a Motorola System V R32V3.2 system. The system works fine, but we need to change the network settings. I've changed the IP address successfully, however I'm lost on the gateway and subnet mask. I've changed the default gateway using

Code:

route -g10.0.8.1

, but it changes back to 255.255.255.255 on reboot. I have not found anything on changing the subnet mask.

Code:

ifconfig
 
lo0      4351    127.0.0.1    255.0.0.0    0    up loop
en596  1500    10.0.8.30    255.0.0.0    0    up bcast(10.255.255.255) loop

Any help would be greatly appreciated.

ifconfig and route and the like aren't going to make any permanent changes on any UNIX system I know.

route -p creates persistent (across reboots) routes on Solaris.

Unfortunately, R32V3.2 does not support the -p option.

You might try using the /etc/defaultrouter and /etc/netmasks files.

Unfortunately, the system does not have those files. Could that be part of the problem?

These files need to be created but won't do anything if the OS doesn't support them. They might be in /etc/inet instead of /etc and/or be named /etc/gateway or whatever.

In any case, nothing forbids you to add an rc script that will do the job, that's what the OSes supporting these files do anyway.
