Bug 99644 – DNS domainname not set when provided by DHCP (unknown_domain)

• Status: RESOLVED INVALID
• Product: Gentoo Linux

[Description Greisberger Christophe 2005-07-20 02:30:30 UTC]

I'm using a single tree for diskless workstations, so I don't want to add 
entries to /etc/hosts since every host has a different name, provided by the 
dhcp server. 
 
But without an entry in this file, hostname -f fails with "hostname: unknown 
host" and the login prompt displays "This is ag01.unknown_domain (....." 
 

Reproducible: Always

You neglected to include the output of emerge --info

Also, which dhcp client are you using?

[Comment 2 Greisberger Christophe 2005-07-20 03:37:30 UTC]

Well, I thought that the emerge --info was not revelant. 
And I'm using dhcpcd. 
 
Anyway, I found I fixed the problem. You can set the status to INVALID. 
 
Cause: DNS entries for the diskless' not present. 
Reason: dhcpcd doesn't (afaik: can't) update M$ DNS server. 
        M$ f*****g DHCP server (Windows Server 2003) doesn't update M$ DNS 
        server, even with the right options ("always dynamically update DNS A 
        and PTR records" & "Dynamically update DNS A and PTR records for DHCP 
        clients that do not request updates") 
Solution: I had to create the entries manually.

I want to remember that you had to tell M$ dhcp server to set DOMAIN, etc .. was
some time though sinve I did it ...
