Configuration hints for self-managed Linux Machines

Sending Hostname for Dynamic DNS

If you want your Linux host accessible via dynamic DNS at <yourhost>.dhcp[-int], make sure that send host-name is used in /etc/dhcp/dhclient.conf.

For more recent versions of ISC's dhclient, the following line in /etc/dhcp/dhclient.conf should suffice:

send host-name = gethostname();

Older versions may need an explicit name there. Please use a name without domain, e.g.

send host-name "johns-laptop";

If nobody else uses that name, you remotely can access your computer by using e.g. johns-laptop.dhcp[-int] (continuing the example from above).
