Trouble with local hostname on same network needing to be changed


iMac, Mac OS X (10.5.6)

    Hello,

     

    Often caused by more than one interface being used, like Airport & Ethernet.

     

    Check System Preferences>Sharing to see the name or change.

    My local hostname get changed daily now.  Somewhat of a mystery to me since I only have one computer ont eh network.  Another software nightmare having to deal with daily.

    Did you ever find out what caused this? I am experiencing this daily and I only have the one iMac connected to my Airport Express.

    It happened to me once. I went to the sharing preferences. The computer's name had not been changed, but it could only be accessed at the new name:

    I clicked "edit" and then it showed up as the new name. I changed it back to the correct name:

    Then I restarted my computer (which may not be necessary). That fixed the problem and it hasn't happened since (knock on wood!).

     

    When/If the problem becomes chronic, turning IPv6 off seems to work for some people. It a quick fix though, not a solution. By turning it off, you are also slowing down the transition from IPv4 to IPv6 as the new, more secure and faster standard protocol.

     

    I've heard people blame routers. I have the latest version of Verizon's FiOS router and yet it happened to me too. So while you may have to upgrade your router for IPv6 to work, it will not solve this particular problem, which I believe is in OS X (Mountain Lion).  I asked if the issue had been fixed with Mavericks but I never got an answer.

    For most people it will be many years until they need to change to IPv6.

     

    Several OSs and routers work better without IPv6.

     

    I always turn IPv6 off.

    And this is why it will take many years.  In fact, if everyone would rather turn it off than fix the problem, it won't ever happen.
