Changed IP address

[pedz]

I just switched from a fixed IP cable set up to a T1 set up and so my IP address changed. I change my ip address for the network adapters and now I can get out to the net but my passwords and everything else is screwy. I believe that netinfo is confused.

When I start server settings, I have three choices in the list to choose from: the old IP address (24.153.157.90), EASESOFTWARE, and Local. My new IP address is not listed.

Somehow I can log in using the admin account but it takes a long time. The normal user account does not work. I believe, somehow, they got stuck into different -- are they called domains? -- in netinfo.

I am not sure but I believe this may all be caused by the initial install. I think I installed Mac OS X Server before I had a fixed up address, then I got a fixed IP address, and now its changed. Somehow in all the migrations, things are all confused.

What is the best way out of this mess?

Thank you,

usually timeouts like that are caused by the upstream server not giving a lookup for the IP address the machine has. It wants to know its name and it wants to be told. netinfo makes things screwy like this.

As for your account not working, that's odd. But I've done mostly local or completely custom things, and haven't had an IP migration after setup. Is there a DNS Server somewhere that will give you forward and reverse lookups like your machine would expect? Can you set it to look at those servers in the manual config?

Once in with the admin account, can you su to the user? Can you id the user? How gone is this user account? Is it local local? Is it supposed to be found at a server that this server used to be?

My long term advice in a lot of this is that domain servers were meant to be local anyway, and that one should maintain a non-routable server room, and portmap into it for security and transferrability reasons. Than your outside IP doesn't affect your inside network, and only explicitly allowed communication can make it inside your server room as the traffic is non-routable by default and only portmapped requests can make it inside.

This coming from my experience with things like this, and not from ever having to set up, say, industrial strength VPN, or a netware network, or VoIP, or look into IPv6 migration; but those are my thoughts with IPv4 and sevurity and switching IPs. Not that this advice does you any good right now anyway.

Well, good luck. If I seem to be more knowledgeable than most, you can e-mail me theed at liquid binary dot com as I traverse these forums very rarely anymore.

As you're using Mac OS X Server, this is a bit more difficult. Take a deep look at Apple's support pages, there should be several entries for changed/changing IPs and hostnames...
