When configuring DHCPD clauses like this one will create fixed assignments
that the computer picks up from DHCPD.
host poohbear {
hardware ethernet 00:0e:f7:a8:41:14;
fixed-address 192.168.7.125;
}
Otherwise simply tell Network Config on each machine that the machine's
address is a specific static address.
Either way you have to setup the hosts files on all the other machines.
Once you get more than three or four machines this can become a hassle.
I simply run a caching name server with a local zone and the DHCP server
setup to update the DNS server. It's a one time hassle getting it setup.
Then new machines on the net get an address, everybody can find it by
name, and Bob's my uncle.
