DHCP causes crash at boot

[Marcus Rademacher]

I have a J6750 running HP-UX 11.0. When going through the initial configuration screens at first boot, I enabled DHCP. When I attempted to logon, the messaging service could not be started, and it forces you to log off. I reinitialized the box, and set it up with a static IP and DNS, and it runs fine (except at boot it says it couldn't resolve its hostname).

I need DHCP so the machine can contact license servers. Is there a change I need to make to my DHCP server to get this to work?

[Marcus Rademacher]

I apologize, I just realized that my subject heading is not exactly right. It should be "DHCP causes unusable system" or something to that effect.

Sounds like a networking issue. Is it on the network now? Can you ping the DHCP servers?

[Marcus Rademacher]

I logged into single user mode and the network was available. I was able to ping my DHCP server, and the machine showed up on the DHCP status page. What I thought was odd was that the hostname didn't show up on the status page. Just a blank entry with the IP address of the HP machine.

For networking issues check the following files :
/etc/hosts ( hostnames and ip's )
/etc/resolv.conf ( DNS servers, domain and such )
/etc/nsswitch.conf ( order for name resolution and other things )
/etc/rc.config.d/netconf ( ip, gateway )

Logon problems like you mentioned are most of the times being caused by network configuration issues.
