This document pertains to the NeXTSTEP 3.3 operating system. NeXTSTEP 3.3 is no longer a supported Apple product.

Why can SimpleNetworkStarter create a NetInfo clone on Intel hardware, but using NetInfoManager doesn't work in NEXTSTEP 3.3 for Intel?
When you use the "Manage Hierarchy" menu in NetInfoManager to make a clone, it actually invokes nidomain -c. When nidomain -c invokes netinfod -c, a byte ordering problem occurs: the byte order of the master's address is reversed.
For example, you clone the /ts domainon the local host rhino. The master of /ts is running on sabre, with a tag of network. Assuming you want to your clone domain to have the same tag as the master, uniform tagging, the nidomain command that gets invoked is:
nidomain -c network sabre/network
nidomain will translate sabre to the IP address 220.127.116.11, and will invoke netinfod as:
The arguments after the -c are the master's host's name, the master's host's IP address, the master's tag, and the new clone's tag. The bug is the reversed byte ordering of the IP address after "sabre".
-Copying the Database
Login as root and launch Terminal. If you just tried using NetInfoManager's Manage Hierarchy menu to create the clone, kill (kill-TERM) the netinfod -c process.
Now change directory to /etc/netinfo, remove network.nidb (or network.mov, or network.tmp) if it exists and run netinfod -c by hand, giving the IP address of the master's host in the correct order. The arguments after the -c are the master's host's name, the master's host's IP address, the master's tag, and the new clone's tag.

-Adding the Serves Property
Next, add a serves property of ./network to the /machines/rhino entry of the NetInfo domain you are cloning.
rhino] niutil -appendprop -t saber/network /machines/rhino serves ./network
Do the following until you get ./network on the serves: line in the output,
Once the database is updated, reboot the clone machine because the new netinfod, the one started by hand with /usr/etc/netinfod -c, isn't a child of nibindd.
Reminder: If you have a three level or greater NetInfo hierarchy, you may need to modify the child as well as the parent domains. See the System Administration Guide, Chapter 10: Configuring a Large Network, located online in /NextLibrary/Documentation/NextAdmin.
