To check, type the command:

showmount -e hostname

Running the showmount command without the hostname parameter will check the local system.

If NFS is not active, you will see a message similar to

showmount: ServerA: RPC: Program not registered

•portmap must be running. Run the following command to check this:

service portmap status

E.2.2. FTP

To enable installation over FTP, you must allow FTP access to the installation directory on the server. This can be

either anonymous FTP access or access through a named account with a password.

If you want anonymous FTP to point to a different directory, you can use symlinks to point to the installation

directory on the server.

E.2.3. HTTP

If you have a web server running and want to enable HTTP access to your installation server, add symlinks from

your document root to the installation server directory to grant access.

The installation server is now ready to use. Record the server name or IP address and the directory path to the

installation directory you created.
