Changing hostname in OSX

by David Hostetler [posted 20080422:09:35 (Tue)]

In what is sure to be a chronic occurrence, I was frustrated by OSX pretending to act like Linux without actually doing the same thing.  Specifically this time I wanted to change the hostname.  The following sort of does it but not really:

  • sudo hostname <newhostname>

According to a post at the bottom of this blog, the following are also necessary:

  • sudo scutil --set LocalHostName
  • sudo scutil --set ComputerName
  • sudo scutil --set HostName

In addition, it's necessary to go into [System Preferences] -> [Sharing] and change the 'Computer Name'.

And all of that won't get around the name provided by DHCP, depending on the DHCP server's config.

(note that this applies to Leopard 10.5.2)
