Chapter 6 Setting Network Preferences 69

To change a server’s IP address:

1 Run the changeip tool:

$ sudo changeip [(

directory

|-)]

old-ip

new-ip

[

old-hostname

new-hostname

]

For more information, see the changeip man page.

Important: If you change your IP address and computer name using changeip while

you are connected to a directory server, you must disconnect and reconnect to the

directory server to update the directory with the new computer name and IP address.

If you do not disconnect and reconnect to the directory server, the directory is not

updated and continues to use the old computer name and IP address.

2 To change the server’s IP address, use the networksetup or serversetup tool (or the

Network pane of System Preferences).

3 Restart the server.

To change the IP address of a computer hosting an LDAP master:

$ sudo changeip /LDAPv3/127.0.0.1 192.0.0.12 192.0.1.10 oldhost.example.com

newhost.example.com

It might be necessary to change the configuration of computers pointing to this

master.

To change the IP address of a standalone server:

$ sudo changeip - 192.0.0.12 192.0.1.10 oldhost.example.com

newhost.example.com

To change a computer’s TCP/IP settings, use the serversetup and networksetup tools.

Important: Changing a computer’s IP address isn’t as simple as changing the TCP/IP

settings. You must first run the changeip tool to make sure necessary changes are

made throughout the system. See “Changing a Server’s IP Address” on page 68.

To list TCP/IP settings for a configuration:

$ sudo networksetup -getinfo "configuration"
