Hello all;

I have many C3600 boxes on a private lan and do not use DNS. I see this
problem a lot when someone wantes to change a host name and does it
wrong.
As Jan said, check /etc/nsswitch.conf to see in what order your system
is doing host name resolving. If you are not on a network get
/etc/hosts first in line. Now make sure that the IP to hostname mapping
in /etc/hosts matches the /etc/config.d/netconf file. This file defines
the information that is loaded to the lan card. If these two files do
not agree X11 will not start. To do all this you will have to boot into
single user mode. I do this by stopping the autoboot, at the boot
prompt type 'bo' (for boot) , then 'y' to interact with the IPL, then
'hpux -is' at IPL prompt. This will boot into single user mode (I hope
you are good with vi).
Starting in single user mode will also bypass all those other boot
issues.

Hope that helps.
