Subject: netgroups FAQ?
Hello guru's. I need to restrict access to a few machines from users on
an NIS network using netgroups but don't know how to do this. We have
though restricted what machines can mount external file systems via netgroups.
I need advice/tips on how to do this.
Answer
On Your NIS server create a file named /etc/netgroup. Create a users
group with the following syntax...
users (,usr1,) (,user2,)
Push the map then go to your client machines. On your client machine
add this line to the end of your /etc/passwd and /etc/shadow files...
+@users::::::
The final thing to do is to edit your /etc/nsswitch.conf file. Change
your passwd and group entries from using nis to compat...
passwd: files compat
group: files compat
Following this model will allow you to restrict user access to client
machines as you deem necessary.
