Create and run the following script. To create the script, execute each of these commands in Terminal (/Applications/Utilities/). Each command is preceded by the dollar sign ($), which represents the Terminal prompt. You must be logged with an administrator account to perform these steps. After the first command (sudo), you will be prompted to enter your administrator password. After typing each command, press Return to execute it. After entering the "cat" command, you will not see a prompt ($) for the next four lines, though you must still press Return after each. For the line that says "[Control-D]", press Control-D.
$ sudo su $ cd /usr/sbin $ cat > EnableUnicastDotLocal #!/bin/tcsh echo domain local > /etc/resolver/local.1 grep -v domain /etc/resolv.conf | grep -v search >> /etc/resolver/local.1 echo search_order 2 >> /etc/resolver/local.1 [Control-D] $ chmod +x EnableUnicastDotLocal $ exit
These steps create an executable shell script named "EnableUnicastDotLocal" that will create and populate the necessary configuration files to enable dual lookups of .local hostnames.
To run the script, execute this command:
$ sudo /usr/sbin/EnableUnicastDotLocal
Important: The address of the DNS server configured by this script for .local name lookups will not change automatically if your default DNS server address changes. (Your DNS server address may change if you change network locations, if a change is made by your DHCP server administrator, or if you change it manually in Network preferences.) To change the DNS server used for lookups in the .local domain, you must run this script again. To disable unicast DNS lookups entirely after running this script, delete the file /etc/resolver/local.1.
Note: For the Active Directory plug-in to work with .local domains, you must update to Mac OS X 10.3.3 or later.
