[X-Unix] Altering system parameters (e.g. IP addresses) on MacOSXserver

[Eric F Crist]

Ken, if you can give me a few hours, I'll get you the complete answer. You lost your connection because the server IP changed. Connect with the new IP and you should be fine, I'll get you the permanent fix when I'm at a terminal and not my blackberry. :)

That much I understood, and I tried doing a "live" reset of the IP  
address, but
then lost connectivity (even after changing my own local net address  
on the
laptop I was using to direct-connect to this machine).  Not sure why  
that happened.

And that, for the long run, is what I am after -- a permanent IP address
change that will survive reboots.

I know that on a Sun, for example, you put the name of the host, as  
seen in
the local /etc/hosts file, in a file called /etc/ 
hostname.<interface>, but
it does not look like Mac OS X uses a mechanism like this.  Maybe OSX  
uses
(or used in the past) some entry in netinfo.  I did not see any  
places in
any boot-time startup files where an ifconfig was issued to set the host
local address (as read from some other file, for example).
