Re: Set hostname via DHCP ?

[Andreas Pedersen <ansenlong@xxxxxxxxx>]

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
}

#Don't remember what happens when a linux client machine has already
