Try ifconfig lan0. Do a man on ifconfig. It can also be used to set your IP address.

Pete,
thank you but id doesn't work.
Reading man I've seen netstat -i. It answer lan1 and my ip address.
Is it right?
Now how can set new IP address?

ifconfig lan1 inet new_ip_addr

Or something like that (asuming you are using IPv4)

Do you want to change lan1's current IP, or configure other virtual interfaces ?

Ok, it's probably not lan0 then. Run lanscan to determine the name of your interface. It sounds like you're using lan1, so the command would be "ifconfig lan1".

Antonio,
once you know the ip-address etc.
if you wish to repeat the part of the installation for setting networks etc.
/sbin/set_parms

then select one of the options:
example:
/sbin/set_parms ip_address

Stephen,
I type ifconfig lan1 x.x.x.17 and after of this when I type ifconfig lan1 it shows my new ip address. Does still remain after reboot?

Fred,
I'm newbie here! I need simple configuration.

Pete,
lanscan doesn't exist!

Peter,
now I try it.

Ok,
ping to another address now works fine!
Ping from another host find this server.
It appears to work fine.
Now reboot.

Question was to know wether you want to change current IP or give your machine a secondary IP.

If you only want to change IP of lan1, ifconfig will change it for current system. To change it beyond reboots, you have to change /etc/rc.config.d/netconf.

Fred

It's /usr/sbin/lanscan, but that shows your hardware (MAC) address, not your IP address.

Re: How can I know my IP address?

Pete Randall — Thu, 07 Apr 2005 10:58:08 GMT

For the new setting to remain after reboot, you would need to change it in /etc/rc.config.d/netconf. Scan down to the section that begins "INTERFACE_NAME[0]=lan1" and change the next line to the new IP address. Better yet, to make sure that all the necessary places are changed, run "/sbin/set_parms ip_address".

Fred Ruffet — Thu, 07 Apr 2005 11:08:08 GMT

Fred

If you want a permanent change, do what Fred/Pete have been trying to tell you.

Re: How can I know my IP address?

Antoniov. — Thu, 07 Apr 2005 11:32:11 GMT

/sbin/set_parms ip_address ask me the ip_address then reboot system; after reboot host has still old ip_address :-(

Now I try change manually /etc/rc.config.d/netconf ...
(I hope remember how work vi)

After making the changes to /etc/rc.config.d/netconf

stop and start the /sbin/init.d/net
by giving the command
/sbin/init.d/net stop
and then
/sbin/init.d/start
that should do it

I hope you have already identified the lan card from the ioscan -funC lan output and have plugged in the cables to the right device.

... and now I understand!
netconf is read only. I can't change with vi!
I guess I have to change with chmod ..
