I know it is possible to set a preferred hostname through DHCP and have the DHCP server automatically setup the forward and reverse DNS for that hostname. On a static IP box without NetworkManager it is possible to add DHCPHostname="DesiredHostname" to the /etc/sysconfig/network-scripts/ifcfg-eth0 script and it will pull down an IP and setup the DNS according to the hostname that you asked. Now the question is does anyone know how to do it with NetworkManager? If have tried adding DHCPHostname="DesiredHostname" to /etc/sysconfig/network-scripts/ifcfg_Auto-SSID as well as to /etc/sysconfig/network without success. Also this is on a laptop with Fedora 16.

So I created the file with my desired host name but it did not send it for some reason. I changed everything back to the default settings and changed my host name to something new and that registers in DHCP.

Try to create a /etc/dhclient-$IFNAME.conf file, like /etc/dhclient-eth1.conf.

Content would be:

send host-name "your_hostname";
request subnet-mask, broadcast-address, time-offset, routers,
domain-search, domain-name, domain-name-servers, host-name;
