Changing server IP

I realize there have been several posts on this issue, but I have an unfortunately unique twist. At my office there is a 10.3.9 server running, and we recently switched internet providers. I was unfortunately not there to prevent the damage. The internet company guy installed a new router with a 192.X address set, instead of our old 10.1.1.X set. Problem is, he did it in the network configuration window and not with changeip, so while it jives with the router and the internet, all other server functions have been shot, like authenticated login (I worked around this changing the authentication to Shadow Password), server update routines, and all internet-based services other than simple access being inoperative. I didn't set up the server initially (wasn't there a few years ago), but I'm pretty sure most things are on a Permanent IP setting.

Question: I think I have the old IP address (fortunately stored in "Favorite Servers" on some of the computers) of the server, though not the individual computers, but that would really only be a login issue. Can I do the following:
changeip old IP (10.X) newIP (192.X)?
Will it simply behave as though it had been run in the first place and everyone lives happily ever after, or did setting the new IP address in the wrong way screw everything up?

First post, so apologies if I missed some utterly relevant thread elsewhere.

The changeip command is made to handle that situation. A different trick may be to reconfigure the router to the 10.1.1.x settings and restore the old ip-nummer on the server. This should work flawlessly, although by changing the passwords setting you might run into problems in the future any way you solve the problem.


Good luck, Kees
 
I'm afraid the individual password settings are going to remain unchanged, since I have no clue where I'd retrieve the old IP addresses. On a related note, is there any way to increase the storage time of the syslog file? It seems to have been setup to 1 day, after which it purges itself. This makes for quite a hassle when trying to find out what happened a couple days after the fact (i.e. impossible)

When you say that I should just set the IP back, do you mean in system preferences? That would indeed be the easiest solution. If it doesn't fly, I'll try the changeip command. Hopefully it'll jive with the router - I think that's why the service guy took the liberty of changing the server IP. Ugh.

Thanks for the help.

Yes indeed, just the network panel in the system preferences menu.


Good Luck, Kees
 
Well goshdarnit, it worked! A simple system prefs reset (accompanied by a not quite so simple router reconfiguration) got everything back to normal. Thanks for the help, all!
