I have a XenServer installation with Debian (lenny) machines created on a daily basis using a script which creates the machine from a template and assigns it with a new hostname.
Our network has a Fortinet 60B appliance which servers as the DHCP server and a Microsoft Windows 2008 DC which also serves as a DNS server. I'd like to configure the VM template to send its hostname to the DNS server when it gets a leased IP from DHCP.
Currently, Fortinet assigns the DC as the DNS server along with the IP lease. I tried adding a 'send host-name "my-host-name"' line to /etc/dhcp3/dhclient.conf, but nothing gets updated in the DC.
