NIS configuration

Vipin Singhal — Wed, 23 Nov 2005 10:05:59 GMT

My server is using NIS. I’m not sure, but I believe all of the users are already in NIS. Is there a way to validate this?
Thanks
Vipin

Hi Vipin,

Check the entries in the /etc/nsswitch.conf file.

#cat /etc/nsswitch.conf
passwd: files nis
group: files nis
hosts: nis [NOTFOUND=return] files
networks: nis [NOTFOUND=return] files
protocols: nis [NOTFOUND=return] files
rpc: nis [NOTFOUND=return] files
publickey: nis [NOTFOUND=return] files
netgroup: nis [NOTFOUND=return] files
automount: files nis
aliases: files nis
services: files nis

The output should be similar to this.

HTH,
Devender

The ypwhich and ypcat commands are the commands to will need to validate this.

The ypwhich command will tell you what NIS server (master or slave) the client is binding to.

The ypcat command will list the accounts in NIS. This could be 'ypcat yppasswd' or 'ypcat passwd' or something else. You will will to verify this for your environment since this name can be specified.

If you have a server that is not in NIS (as validated by the ypwhich) then check the local passwd file.

Q. how will i create the new users in the same group?
A. I don't know how you would do it but I would give them a common group ID.

Q. How will i select their home directory?
A. I don't know how you would do it. It is common in an NIS environment to automount home directories so that the user has the same home directory regardless of the machine he is currently working on.

Q. how will i define their group?
A. I don't know how you will define their group. I would make an entry in the group map and then when you create the passwd entry give them this group ID.

Once again, you don't seem too interested in learning on your own. Get yourself a copy of
O'reilly's "Managing NFS and NIS"; it's an excellent reference and will deal with all of your questions.

You create users in the same group by using options in the useradd -G command.

Some people build a standard user template, put it in /etc/skel and that keeps all users in the same group.

In an NIS environment users should be created on the NIS Master. ypmake pushes them to the NIS slaves.

The latest questions you have cannot be answered with confidence because there can be numerous methods of accomplishing this task - and all achieve the same result.

Does your environment modify the NIS passwd file directly? Or do you use the adduser utility?

This is one example.

Either method can work but this depends on the environment.

SAM would be the 1st place to look.
