adjust it as required for your environment and security requirements.
After setting up a NFS Server, you will be able to use the 'network'

installs.</P>
<P CLASS="headings-special-western">Step 1</P>
<P CLASS="western" STYLE="margin-left: 0.8in">On the designated
server machine, make sure that NFS is installed and running. For
this example, my server's name is <FONT FACE="Courier, monospace">'fileserver.eastcott.net'</FONT>.</P>
