Network Information Services (NIS and NIS+) Guide

Removing NIS+

This section describes how to use the NIS+ directory-administration commands to perform the following tasks:

Removing NIS+ from a Client Machine
Removing NIS+ from a Server
Removing the NIS+ Namespace

Removing NIS+ from a Client Machine

This section describes how to remove NIS+ from a client machine.

Note: Removing NIS+ from a client machine does not remove the NIS+ name service from your network. See Removing the NIS+ Namespace for information on removing the NIS+ name service from a network and returning to either NIS or /etc files for naming purposes.

To remove NIS+ from a client machine that was set up as an NIS+ client using the nisaddcred, domainname, and nisinit commands, use nisclient -D.

Note: The nisclient -D command does not restore the previous environment. To restore the previous environment, use nisclient -r.

Restoring to Previous Network Environment

To remove NIS+ from a client machine that was set up as an NIS+ client using the nisclient -i script, run nisclient with the -r option, as follows:

clientmachine# nisclient -r

nisclient -r undoes the most recent iteration of nisclient -i; it restores the previous naming system used by the client, such as NIS or /etc files.

Removing NIS+ from a Server

To remove NIS+ from an NIS+ server, use nisserver -D.

Note: Removing NIS+ from a client machine does not remove the NIS+ name service from your network. See Removing the NIS+ Namespace for information on removing the NIS+ name service from a network and returning to either NIS or /etc files for naming purposes.

Removing the NIS+ Namespace

To remove the NIS+ namespace and return to using either NIS or /etc files for name services, do the following:

Remove the /etc/.rootkey file from the root master.
```
rootmaster# rm -f /etc/.rootkey
```
Remove the groups_dir and org_dir subdirectories from the rootmaster domain.
```
rootmaster# nisrmdir -f groups_dir.domainname
rootmaster# nisrmdir -f org_dir.domainname
```
Where domainname is the name of the root domain, for example, wiz.com.
Remove the root domain.
```
rootmaster# nisrmdir -f domainname
```
Where domainname is the name of the root domain, for example, wiz.com.

Locate and kill the keyserv, rpc.nisd, and nis_cachemgr processes.

rootmaster# stopsrc -g nisplus
rootmaster# stopsrc -s keyserv

Create a new domain.
```
rootmaster# chypdom [-I|-B|-N] name
```
Where name is the name of the new domain; for example, the name of the domain before you installed NIS+.
Restart the keyserv process.
```
rootmaster# startsrc -s keyserv
```
Remove the /var/nis directory and files.
```
rootmaster# rm -rf /var/nis/*
```
If you are running in NIS-compatibility mode, also enter the following:
```
rootmaster# rm -rf /var/yp/ypdomain
```
Now restart your other name service (NIS or /etc files).
