Re: [CentOS] Set hostname via DHCP ?
If your trying to make CentOS/Fedora boxes to get hostname remember you need
to have localhost.localdomain in /etc/sysconfig/network.
HOSTNAME=localhost.localdomain
see around line 252-261
/etc/sysconfig/network-scripts/network-functions
need_hostname ()
{
CHECK_HOSTNAME=`hostname`
if [ $CHECK_HOSTNAME = (none) -o $CHECK_HOSTNAME = localhost -o
\
$CHECK_HOSTNAME = localhost.localdomain ]; then
return 0
else
return 1
fi
}

Hi.
I just setup one of my machines as a DHCP server. I'd like it to handle
the hostnames of clients. Don't know if this is an orthodox thing to do
(feel free to add your comments :oD). Here's the server's relevant lines
of dhcpd.conf:
--8---
...
# Envoyer les noms d'hôtes aux clients
use-host-decl-names on;
# Adresses statiques
host babasse {
hardware ethernet 00:0d:61:ae:6b:8f;
fixed-address 192.168.1.249;
}
--8---
Now the question is: how should the configuration look like on the
client side, so the hostname gets effetively fetched from the DHCP
server? During the initial install, I assigned hostnames manually to
every machine.
Cheers,
Niki Kovacs

That's because libcrypt from glibc only supports md5 and DES algorithms, which we don't want.
