Question

what is 'changeip'. how do I use it?

I have just set up a MacPro with dual NIC's and followed Apple's recommended install of having a modem/internet on en0 and switch/LAN on en1. During the install process I did as requested and entered out ISPs settings on en0 and progressed with the rest of the install. I have DNS errors, and also keep seeing our ISPs (instead of our server's) details showing up through the server in places like sharepoints.
Searching the threads here I see members with similar problems who are being told to use 'changeip'.

I am a complete newbie, I don't understand commandline. What I'm looking for is a basic 'do this, then this' type response to help make our server happy.

Here's the error:

Aug 8 08:19:27 xserver servermgrd: servermgr_dns: configured name and reverse DNS name do not match (xserver.local != dsl-217-155-192-186.zen.co.uk), various services may not function properly - use changeip to repair and/or correct DNS
Aug 8 08:19:48 xserver servermgrd: servermgr_dns: no name available via DNS for 192.168.2.1
Aug 8 08:19:48 xserver servermgrd: servermgr_dns: no reverse DNS entry for server, various services may not function properly

Can anyone shed any light here please?

MacBookPro, Mac OS X (10.4.10)

No, Apple doesn't recommend that as a "always do this" procedure. What was your specific goal ?

Especially if you're completely new to this, let your router take care of NAT for you.

With all due respect your company should consider hiring someone, there are too many things you need to learn all at the same time. If you were tasked with driving a bus for a company event, you'd decline if you'd never driven manual transmission before, let alone lacked a driver's license (and experience) qualifying you to drive a bus.

Start by reading through Apple's server documentation.

Next, "google" for bash/shell tutorials, there are many.
Here's one
http://developer.apple.com/documentation/OpenSource/Conceptual/ShellScripting/in dex.html

For anyone wanting to manage a server, be it Apple's OS X or other bsd/unix/linux OS, knowing the "commandline" is an essential part of your toolkit.
I do mean essential.

With OS X Server, command-line ability will often allow you to make a quick fix where without it you'd be faced with a wipe-and-reinstall.

At this point, you may do best to do just that, after re-planning your server configuration and learning some DNS fundamentals.

OS X Server must have working forward and reverse DNS entries for its FQDN. You don't have to run DNS on your OS X Server itself if you have existing DNS servers.

Thanks for the response Dave. I must admit to feeling a little deflated though. Of course I wouldn't try to 'drive the bus' nor would I expect a video newbie to be Final Cut Certified Pro which is actually what I am. I don't intend to become a network specialist overnight, server technology just isn't my area. I'm new at this and was looking for help in this here support group.

Also, we can't afford a Pro to do this for us, we're a small company in our first year - we've been quoted £1000+ for the set up which when added to the cost of the server is to much to cope with. The Apple documentation is very good, it doesn't assume the owner of the server need be a technical whiz, which is why I was able to get so far. It just doesn't explain how I can get rid of my ISPs details in my config thereby allowing LDAP to work properly with properly resolving DNS.

I really don't want to erase and install - I have done this twice already. I'm almost there with what I need which is.. internet en0, LAN en1. We would like to run OpenDirectory, share files and keep a calendar. That's it.

Thanks again.

Hi neale johnson-

Of course a consultant would be the best way, but I also understand the need to be the "jack-of-all-Trades" that must deal with such things.

Here is Apple's manual on command line documentation: Mac OSX Server Command-Line Administration For Version 10.4 or Later Second Edition

The answers are in there.

Another excellent resource for a person in your predicament is Schoun Regan's book titled Mac OS X Server 10.4 Tiger. It can be helpful in guiding you through daunting tasks like this.

Luck-

Yup, Schoun Regan's books are excellent.

Also make sure to run, not walk to buy M. Bartosh's 10.3 Admin book.
http://www.oreilly.com/catalog/macxserver/
Do not pass up on it because it's "only" for 10.3 - most things will still apply.
Don't buy the 10.4 PDF version without first investing in the 10.3 book.

Also look for John DeTroye's Tips & Tricks for some good, basic walk-throughs.

Thanks all for the advice. I have the server as 'standalone' at the moment. We are all able to see shared folders which for now is cool.

I have Schoun Regan's book on order, so now begins my learning curve towards being able to set this thing up right.
