Networking/Routing

[Bryan W. Maxwell]

Im trying to set up my home system as 192.168.2.0, but somehow the local 
loop lo0 is still on 127.0.0.1. How can i set up my local network to be the 
other address. Also when setting up a serial line connection, how can I 
tell both sides are pinging. I can ping one side, but the other gives me a 
sendto:Network dropped connection on reset. The commands im using are
slattach -h -l -n -s /dev/cuaa0     ifconfig sl0 192.168.2.2 192.168.2.3 up
Thanks for all the help in advance, 
Bryan
