lan1 loose configuration rebooting the system

[Andrea Corrado]

Hi,
everytime i reboot my D380/1 HP-UX 10.20 (A3577AR) the lan1 interface card (100BT) loose the right
IP address (from 10.0.10.1 to 0.0.0.0).
I use SAM to reconfigure manually the card after rebooting the system.

I get the following message in /etc/rc.log

......

Any suggestion?
There is a way to resolve this problem?
Thanks.

Is 10.0.10.1 a valid IP address? Looks like a problem to me. Is this newly created also? This would also change your netmask if so.

All patched up?

Actually shouldn't the netmask for a Class A network be 255.0.0.0

10.0.10.1 being a Class A Ip Address, I think your netmask may be wrong.

One more thing to check cause I've seen this happen sometimes. Make sure that you don't have any old netconf, or netconf.old or any netconf files in your /etc/rc.config.d
