Either add the dns entry to the different dns servers / client hosts files or try to configure dynamic dns updates (don't ask me ;) > 3) What should I put in /etc/rc.conf for hostname= Whatever name you like. > I need the hostname in order to serve let other users access the box but I cannot use redirectional services from the internet or ask the network admin to assign me a specific address. I need to come up with a plug and play box. Hmm that sucks.. There is something about dynamic dns updates using dhcp, if the dhcpd servers you talk to understand that, you can send your hostname to the dhcp server.
