HOSTNAME variable

[ARNAUDOV Krasimir]

Hello,
I have had the same problem.
I have modified fai-chboot so HOSTNAME is added to the pxe boot file when it's generated.

Find the row and add HOSTNAME=$host:
$append="append $initrd $bootprot $rootfs HOSTNAME=$host $opt_k $flags $action\n";

Regards
Krasimir Arnaudov

Subject: Re: HOSTNAME variable

sorry to bother again about this issue, but now i checked that my DNS server works correclty:
i can boot into the live system and "# dig" reverse DNS queries.

but "# hostname" still returns "fai-live-host" (which is also in /etc/hostname).

"# hostname -f" fails (temporary failure in name resolution). if i log in to the live system and change the hostname to the correct hosname by hand, "# hostname -f" also works.

the ${HOSTNAME} variable is always "fai-live-host".


again my question: where is the hostname (and the HOSTNAME variable) set during the FAI boot? how can i debug what's happening there? or is there another check i could run?

any ideas?

thanks in advance!
