 Posted: Wed Jan 12, 2011 10:33 pm Post subject: [SOLVED] dhclient doesn't set domain-name |
 |
|
Hi,
I have network with an own domain name (intern.example.org for example).
A Debian system is running a dhcpd (isc-dhcpd-4.1.1-P1) and a DNSd.
Everything is working fine:
Other clients (Windows, Debian and Ubunt systems) will get the network configuration by the DHCP. Every client will set the domain-name option for example correctly.
Now I added my first Gentoo system to my network. It's running dhclient (isc-dhclient-V3.1.2p1-Gentoo).
The problem is, that dhclient does not set the domain. For example, after dhclient received the configuration from the dhcpd, my "/etc/resolv.conf" looks like
| Code: | gentoo ~ # cat /etc/resolv.conf
# Generated by dhclient for interface eth0
search intern.example.org
nameserver 192.168.1.2 |
but I expected
| Code: | domain intern.example.org
search intern.example.org
nameserver 192.168.1.2 |
I captured the DHCP request and ACK, I can see that dhclient is requesting the domain-name as configured, and also receiving the domain-name... but it isn't set.
Here are some configuration files:
| Code: | gentoo ~ # cat /etc/conf.d/net
# This blank configuration will automatically use DHCP for any net.*
# scripts in /etc/init.d. To create a more complete configuration,
# please review /etc/conf.d/net.example and save your configuration
# in /etc/conf.d/net (this file :]!).
config_eth0=( "dhcp" )
module_eth0=( "dhclient" ) |
| Code: | gentoo ~ # cat /etc/dhcp/dhclient.conf
send host-name "gentoo";
request subnet-mask, broadcast-address, time-offset, routers,
domain-name, domain-name-servers, domain-search, host-name,
netbios-name-servers, netbios-scope, interface-mtu,
ntp-servers; |

"search" does the same thing as "domain" here, however search lets you list out multiple names, whereas domain is just a single value.
There's a man page for resolv.conf(5) that shows how this process works. |

No, it doesn't the same thing here: Without "domain",
won't work for example.
You need both. And remember, Debian and Ubuntu will set both values like expected.

Oh, well my brain apparently failed today. I've never actually encountered that problem (in over 20 years  ) |

check if you have your hostname (without domainname) listed in /etc/hosts.
If you remove it, hostname -f should work again.

I've had a similar problem with a missing local domain name, where the answer was to use eg:
xxx.xxx.xxx.xxx localhost.localdomain localhost
and not
xxx.xxx.xxx.xxx localhost localdomain.localdomain
in /etc/hosts.
I can't imagine why this would make a difference, but apparently it does. It might work
for DHCP as well.

Yes, the hostname without the domain-name was listed in the hosts file.
I removed it and hostname -f is now working as expected.
Thank you!
