Host name lost during session

John Dorak — Wed, 08 Aug 2007 08:52:43 GMT

Our HP Itanium system: HP-UX ia64bld1 B.11.23 looses its host name after running some build scripts. The scripts do use the hostname command but no changes to the host name are done. I checked file: /etc/rc.config.d/netconf and it has not been changed.

Any ideas?
Thanks,
JJD

Hi John:

I suggest you examine the use of the 'hostname' command in the scripts you run. Executing 'hostname name' will change the hostname but not modify the 'netconf' file.

Regards!

Given the circumstances as you state them, I can only suggest that it must be divine intervention.

What did your hostname become? Was it null or was it something like -v or -h or similar? HP-UX hostname command (unlike Linux and other flavors) has no options whatsoever and takes whatever is supplied on the command line as the new hostname (the hostname man page is helpful here). Either your build scripts were not designed/tested for HP-UX or some novice sysadmin logged in as root and played with the hostname command assuming that all Unix commands are the same.

Just found the culprit, this script of course is used on multiple Unix systems and an error path we don't normally go down had a hostname -s in it.

Thanks for the pointers.

I guess someone intended to use uname -s to get the hostname.

Exactly.
