    Hi Guys,

    I have been a long time follower and have come across a problem that I cant seem to find on the forums and am hoping that someone can help me…

    The server (OSX 10.4.11, Intel Xserve: model MA409LL/A) has a problem where the Server Admin tool will not allow for anyone, locally and remotely, to connect to the server. This in turn is stopping the Printer sharing service from running.

    I have so far found that this is occurring because servermgrd is not running, and it cannot start because the hostnames locally and the DNS do not match up. After spending 6 hours of adhoc learning (which is the best thing ever!) i have ran the following commands in Terminal on the server with the following results:

    ———————————————————————————————-

    londmstwist:/usr/sbin admin$ sudo scutil –get HostNamePassword:
    londmstwist.emea.schawk.com
    londmstwist:/usr/sbin admin$ sudo changeip -checkhostname

    Primary address = 10.32.9.57

    Current HostName = londmstwist.emea.schawk.com.emea.schawk.com.emea.schawk.com.emea.schawk.com
    DNS HostName = londmstwist.emea.schawk.com

    To fix the hostname please run /usr/sbin/changeip for your system with the
    appropriate directory with the following values

    /usr/sbin/changeip 10.32.9.57 10.32.9.57 londmstwist.emea.schawk.com.emea.schawk.com.emea.schawk.com.emea.schawk.com londmstwist.emea.schawk.com

    example:

    /usr/sbin/changeip /LDAPv3/127.0.0.1 10.32.9.57 10.32.9.57 londmstwist.emea.schawk.com.emea.schawk.com.emea.schawk.com.emea.schawk.com londmstwist.emea.schawk.com

    londmstwist:/usr/sbin admin$ sudo changeip – 10.32.9.57 10.32.9.57 londmstwist.emea.schawk.comemea.schawk.com.emea.schawk.com.emea.schawk.com londmstwist.emea.schawk.com

    Current HostName = londmstwist.emea.schawk.com.emea.schawk.com.emea.schawk.com.emea.schawk.com
    DNS HostName = londmstwist.emea.schawk.com

    /usr/sbin/changeip 10.32.9.57 10.32.9.57 londmstwist.emea.schawk.com.emea.schawk.com.emea.schawk.com.emea.schawk.com londmstwist.emea.schawk.com

    example:

    /usr/sbin/changeip /LDAPv3/127.0.0.1 10.32.9.57 10.32.9.57 londmstwist.emea.schawk.com.emea.schawk.com.emea.schawk.com.emea.schawk.com londmstwist.emea.schawk.com

    londmstwist:/usr/sbin admin$

    ———————————————————————————————-

    As you can see for some reason the hostname from sudo scutil -get hostname (Londmstwist.schawk.com) does not match the current hostname when running sudo changeip – checkhostname (LONDMSTWIST.EMEA.SCHAWK.COM.EMEA.SCHAWK.COM.EMEA.SCHAWK.COM.EMEA.SCHAWK.COM). I have check the DNS server and have set 10.32.9.57 to resolve to LONDMSTWIST.EMEA.SCHAWK.COM , which is what rightly comes up for the DNS hostname in the changeip – gethostname.

    SOrry if I’m rambling but I have now spent a full 24 hours on this thing and am hitting a brick wall.

    ANY help will be greatly appreciated!

    Thanks

    An Update:

    I got the hostname to change by running sudo hostname server.domain.com

    I ran sudo changeip -checkhostname and the hostname and DNS hostnames are the same! YAY!!!!

    I rebooted the server and servermgrd still keeps crashing, when i check console.log the error message is:

    Sep 3 11:02:52 londmstwist crashdump[1264]: servermgrd crashed
    Sep 3 11:02:53 londmstwist servermgrd: servermgr_dns: gethostbyaddr() and reverse DNS name do not match (londmstwist != londmstwist.emea.schawk.com), various services may not function properly – use changeip to repair and/or correct DNS
    Sep 3 11:02:53 londmstwist crashdump[1264]: crash report written to: /Library/Logs/CrashReporter/servermgrd.crash.log

    Can someone please give me some guidance in decrypting the error?

    Thanks

    One thing I see is that the reverse DNS lookup is now matching the forward lookup. What do you get when you enter the command: [code]host 10.32.9.57[/code] If this does not return “LONDMSTWIST.EMEA.SCHAWK.COM” then you need to edit your 9.32.10.in-addr.arpa file on your DNS server and change the entry for 57 to “LONDMSTWIST.EMEA.SCHAWK.COM.”. Notice the period at the end of the FQDN. This is VERY important.

    You don’t mention what you’re using for your DNS server. What are you using?

    Hope this helps.
