How to Install and Configure the QAS NIS Components ? (4290493)

How to Install and Configure the QAS NIS Components on Linux / Unix (non Solaris)?

Installing and Configuring the QAS NIS Components

To ensure that the NIS proxy agent daemon, vasypd, does not cause any system hangs when you install, configure,

or upgrade it, follow the steps for each supported Unix platform outlined in this section.

Note: Before installing and configuring the QAS NIS components, you should have previously installed

the QAS agent software and joined the Unix machine to an Active Directory domain.

Installing and Configuring the Linux NIS Client Components

You can find the vasyp .rpm file in the client directory for your Linux operating system on the installation media.

To install and configure vasyp on Linux

1. Ensure that the system ypserv daemon is stopped by running the following as root.

# /etc/init.d/ypserv stop

Note: You do not need to do this if you have not previously configured ypserv.

Note: This option is not available on SuSE Linux (10.2) or on Red Hat.

2. Ensure that the system ypserv daemon is not configured to start at system boot time.

The commands for doing this vary for the different supported Linux distributions. Please see your operating

system documentation for instructions on disabling system services.

3. Ensure that the system ypbind daemon is not running by entering the following command

# /etc/init.d/ypbind stop

4. Ensure that the system ypbind daemon is configured to start at system boot time.

The commands for doing this vary for the different supported Linux distributions. Please see your operating system documentation for instructions on enabling system services.

5. As root, mount the QAS installation CD, change directories into the linux directory, and run the following

command:

# rpm -Uvh vasyp-<version>.<build number>.rpm

As part of the install process, vasyp is registered with chkconfig to start at system boot time.

6. Configure the ypbind daemon to only talk to NIS servers on the local network interface by modifying

/etc/yp.conf to contain only the following entry:

ypserver localhost

You can use either localhost or the actual hostname.

7. Set the system NIS domain name to match the Active Directory domain to which you are joined by running the

following command as root:

# domainname example.com

where example.com is the domain to which your machine has been joined.

Set the NIS domain name permanently on Red Hat Linux by modifying /etc/sysconfig/network to have

the following option:

NIS_DOMAIN="example.com"

where example.com is the Active Directory domain to which the machine is joined.

On SUSE Linux, modify the /etc/defaultdomain file to include only example.com where example.com is

the Active Directory domain to which you are joined.

8. Start vasyp with the following command:

# /etc/init.d/vasypd start

9. Start ypbind with the following command

# /etc/init.d/ypbind start

You can now use the NIS utilities like ypwhich and ypcat to query vasyp for NIS map data
