Assigning Host Name Ineffective and Causing Errors
I have just installed Fedora Core 3 and have been trying to assign the machine a name (hostname?) so I wouldn't have to rely on using it's internal IP for all of my network configurations. I'm on a small network, the machines are inside a modem/firewall/router and a hub. The modem handles DHCP and of course the ISP handles DNS. When I tried to change the hostname (what I understand to be the linux ver. of machine name) I used the command hostname, altered /etc/hosts, and etc/sysconfig/network but I kept recieving errors.
The errors varied from "improper hostname", "unable to resolve hostname", to Samba breaking and the machines being unable to communicate. Could anyone tell me a SAFE, CERTAIN way to change my hostname to something aside from localhost? There is no reason that I cannot assign a host name without a domain is there? Any help and enlightenment is appreciated :)
