changing IP configuration

rob_xx17 · 12-06-2004, 07:59 AM

Hello everybody.

I just installed a copy of Solaris and I need to change IP configuration. More specifically, I have default router set as "autodetect" but I need to change it to a specific IP address. I realize that it's Solaris 8, but I believe that I need to use a terminal (there's no GUI for that) so it should be more or less universal accross all UNIX/Linux platforms. I appreciate any help.

Try the command

route add default gw <ip of the router>

replacing <> with the ip of your router.

I think it worked on our solaris box the last time I had the misfortune of working with it. Tough to learn Sun's OS is... but it is rock solid.

The route add command will only temporarily solve the problem.
If you reboot you will lose the configuration info you entered with this command.

You will need to create an /etc/defaultrouter file and simply put in the IP address of your router there. This way your router info will remain intact after your next reboot.

Hope this helps.

Thanks. I tried the "route add default gw <ip of router>" command but I received "router: bad value" reply. So I tried pinging it and I received "ICMP Host Unreachable ... no answer from ..." What could be the problem? I know that I'm connected via Ethernet to the network?

The command is "route add net default <IP address>".

If you are not getting a ping reply from your router, as you just mentioned, then you have other issues possibly related to your router config.

would you say that it's a configuration local to my host or a configuration of the router that I'm pinging?

The command is:

Code:

route add default <IP address>

gw and net keywords are for linux.
