HP-UX

This will most likely be a real dumb question for a HP-UX admin, but here it goes anyhow.

lan0 - is up and configured
lan1 - is down, I want to bring it up.

lanconfig....ifconfig is there a difference?

My real question is, in solaris there is an /etc/hostname."?" file, is there a corresponding file in HP-UX. I see one, for the existing NIC but the naming convention seems strange to me.

I.E. HP-UX: /etc/hostname.btlan4
lanscan shows no lan4, rather a lan0 and 1.

If someone could point me to the documentation or give me a quick reply it'd be much appreciated.

HP-UX 10.20 (Yah she's old)

lanconfig configures link level stuff. It and lanadmin together are close to ndd on Solaris. ifconfig is very close between the two OS's. One gotcha: hp-ux has no ifconfig -a. Use netstat -in instead.

HP has many lan drivers and one is named btlan4.

A place to start is:
ioscan -fnClan
which will list your lan cards and tell you which drivers claimed them.
And:
swlist -l file LAN\*
will list the files that make up your installed lan products. Look for and read any documentation.

Running the ioscan I see btlan4 claimed them both. If I bring the second interface up with an IP and hostname, will I need another hostname.btlan4 entry under /etc?

I have never used btlan4 and I'm not familiar with that file.

I just found an old hp box with btlan4 in operation! I had a rough time finding the files, this driver didn't have "LAN" in it's product name. I got the files with:
swlist -l file 100BT-GSC\*
which isn't exactly obvious.

There is no hostname.btlan4 there and we don't that file on our box. This would imply that someone may have customized your setup.

Had you followed HP's standard, you would need to modify two files both in /etc/rc.config.d The first is netconf which is where you set the ip address, netmask, and other general IP stuff. And there is hpgsc100conf which is where you set any btlan4 specific parameters.
