Q: How to prevent server.app from loading on system boot?

I have myself locked out: "Network logins are unavailble". How can I prenvent server.app from loading on system boot? I need to reconfigure a few network settings. Problem is, I only have one Mac available. I need a login into this one with NO server running.

 

Any advice, command line tools to use from revovery mode terminal.app would great.

    So there's no non-network admin login and no alternate boot device and no other Mac?   That can be a rather tough spot.   Either boot from the recovery partition or the Internet (if your Mac supports that), or try How to start up your Mac in single-user or verbose mode - Apple Support and use the command line to sort out the problem here — not that figuring out what's wrong here and resolving it will necessarily be entirely straightforward using that approach.   Alternatively, get somebody to create a bootable USB device and mail it to you.  This assuming Time Machine can't revert to prior to the problem.  Another approach is to nuke and pave — wipe and reinstall — the configuration; to start over.

    Thanks for your reply,

     

    I tried single user mode. The problem is I find myself in a "read-only file system". So, there is no chance to modify a thing.

     

    I guess I have to re-install the OS from recovery mode. Before I start the process I have one more question, because I really would like to avoid to wipe clean the entire OS partition. Dose the re-install of the OS give me a clean configuration or does it take over previously done settings?

     

    Thanks, Jurgen

    You can switch the file system to read-write.  (See here or here, etc.)

     

    I do not know why your network logins are blocked, so I don't know whether reinstallation — short of wiping and reinstalling — will resolve the issue here.

     

    There's no chance you can create or acquire a bootable OS X disk somewhere else, or have somebody create and mail you a flash drive with the necessary software bits?

    MrHoffman thanks alot,

     

    I reinstalled the OS, not clean though, back to square one. Then in single user mode with a writable file system thanks to yur links, I simply renamed the server.app directory as a beginners first shot. All it did was, that the msg "Network accounts are unavailble" disappeared. However, the login did not work.

     

    How can I now disable all services of the server from the command line and tell the OS not to login with network accounts? I think, that could bring me back into the game. BTW, the server does know my local user (admin) account as well as the same user, names and all that! I thought I needed to create myself there in order to have access to the server resources.

     

    As you can see from my user level in this forum I am not expert, but have some low level knowledge of unix systems, beginners level.

     

    All your help was and will be very much appreciated.

     

    Thanks, Jurgen

    If you have a local admin account, fix the problem from there.


    Or with no alternate boot device, no backups, no access to another Mac, and an unwillingness to get a boot device mailed?  Just wipe the disk and start over again.

    Got my problem solved eventually. Case closed!

     

    I wanted to write more, but it appears to me that there is either a too short timeout while typing a msg in here or "someone is listening" while I am typing... kind of censorship? I am sending this now before I am getting kicked out again.

     

    Thanks to all helpers

     

    UPDATE: Being kicked out happened THREE times. Anytime when I was about to write some critical remarks against Apple.
