Solaris 10 adding/seeing 2nd Nic

jonfa · 05-02-2007, 08:24 AM

Hi All,

I setup a Solaris 10 machine with 2 nics, but only one nic is recognized when I do a:

/sbin/ifconfig -a

They are identical nics. Can someone point me to the proper way to add & configure the nic.

I did a:

/usr/sbin/prtconf -pv | more

and it shows both nics.

Thanks

Code:

/sbin/ifconfig -a plumb

should make the second NIC visible.

You'll need more settings if you want the interface to stay after a reboot. The way to do it depends on whether you want a fixed IP or a DHCP one.

/sbin/ifconfig -a plumb worked...Thanks!

How do I make the settings permanent for a static IP?

You are likely to already have a file named "/etc/hostname.<ifname>0" which sets the IP for the first NIC.

Just create a file names "/etc/hostname.<ifname>1" containing the new NIC settings.

I currently have a /etc/hostname.pcn0, but all it contains is my hostname. If I create a /etc/hostname.pcn1 for the second nic where do I make modifications to specify the ip address and netmask?

Do I modify a file in /etc/inet?

Can I use ifconfig to specify the ip, netmask, gateway, etc...?

Thanks for the help.

The same way it is done for the first nic.

Yes, you can add the new "IP hostname" line to the /etc/hosts (a.k.a. /etc/inet/hosts).

Everything in the /etc/hostname.xxx is automatically processed by ifconfig.
You can directly put the IP address here if you don't want to use the /etc/hosts file for name resolution.
netmasks are better set in /etc/netmasks.
The (default) gateway is set in the /etc/defaultrouter file.
