NetInfo
Create a clone NetInfo server with SNS 
¬
If your two-level network has more than two or three computers, you should set up one or more clone NetInfo servers to provide a network back up in case the master NetInfo server fails.

As a rule of thumb, set up one clone for every ten computers.

You can set up the clone server on any computer (except the one that runs the master server). 
¬
BEFORE YOU START: Make backup copies of any /etc/netinfo databases for any domains you wish to alter. 
¬
1	Log in as root on the computer where you want to set up the clone server.
	If you don't log in as root, you can type the root password when 
	you start SimpleNetworkStarter. 
¬
2	Double-click SimpleNetworkStarter in /NextAdmin. 
	SimpleNetworkStarter checks the existing /etc/netinfo databases and makes copies. You can choose Log from the SNS menu to monitor SNS operations.

	CAUTION  If your SimpleNetworkStarter session fails, you must restore the previous /etc/netinfo files yourself. Be sure you made backup copies before you proceedÐfor example, by copying /etc/netinfo/* to  /etc/netinfo/*ORG to save the original files.
¬
3	Click the option "Provide the services specified below" in section 1 
	of the SimpleNetworkStarter window ;../Reference/Tools/SimpleNetworkStarter/SimpleNetworkStarterPanels/SimpleNetworkStarterWindow.rtfd;;¬.
¬
4	Skip section 2 in SNS' window.
¬
5	Check the appropriate options in section 3 of the window ;../Reference/Tools/SimpleNetworkStarter/SimpleNetworkStarterPanels/SimpleNetworkStarterWindow.rtfd;;¬.
	You may want a computer to host a clone NetInfo server and some other network services. If your network has many computers or heavy network traffic, you may want a computer to host just the clone NetInfo server. 
¬
6	Click Configure.
¬

SimpleNetworkStarter creates the directories you checked and sets up a clone of the root domain that has the tag name network. 

If you want to examine the SNS log after you've finished creating the master server, you can use the Edit application in NextApps to open /usr/adm/SNS.log.
