I have a small network set up with one main NIS server. All the other linux machines go to him to authenticate for logging in. I would like to disable a local machine's root account from "su'ing" to another user contained in the NIS domain. Currently if I gain root access to any local machine I can then change to any other user and look at their home directory, even though the root accounts are different from the local machine and the NIS server. As you can see I'm pretty new to NIS, is there something simple I didn't set up right? I figure this is quite unsecure, since anyone could potentially hook up a new computer to the domain and then su to any other user. The only way I know around this is to restrict what ip's may log in and then manually set the root passwords of each local machine. Any help would be appreciated.
