UNIX for Dummies Questions & Answers

Hi,
what are the basic steps/command to configure a new nic (2nd) on Solaris 9?
10x N.

you would have to know what type your nic is.
for example on a qfe card you have to "activate" your interface:
# ifconfig qfe1 plumb
now you can configure it with your new ip address
# ifconfig qfe1 192.168.0.2 netmask 255.255.255.0 broadcast 192.168.133.255 up
and it is online! but only until a reboot. if you want to set it permanently you would have to edit following files:
/etc/hostname.qfe1 --> IP or hostname (must be in /etc/hosts)
/etc/netmasks --> if you are in a different subnet than the first one
done... ;-)

or do you want to activate a failover nic? then ask again and you will get an answere ;-)

gP

many thanks!

Ermm... maybe I'm being stupid but I thought you also have to edit files in (it must depend on your distro I guess)

/etc/sysconfig/network/

If you do need to edit these files, you'll probably already see something which looks like

/etc/sysconfig/network/ifcfg-eth0

If you see that, the quickest thing to do would be to

cp /etc/sysconfig/network/ifcfg-eth0 /etc/sysconfig/network/ifcfg-eth1

The edit it

pico /etc/sysconfig/network/ifcfg-eth1

Just change the hardware address and the IP setting then run

/etc/init.d/network restart

Voila, you should have a new interface available. That will load at startup too.

Note: Your network script paths may vary depending upon the distro you have

It does differ across various flavours of Unix/Linux. The original poster stated they were using Solaris 9, and the procedure pressy posted is correct for this OS.

You posted the procedure for a Linux distro - which is still useful for people needing to set up a NIC under Linux
