Subject: Something is broken with the NFS mount!
This email is generated by the NFS Watcher script on $hostname...
I noticed the NFS export from ${ip_add} was NOT mounted, but
whenever I tried mounting it, something didn't work.
Remember, until the NFS export from ${ip_add} is properly mounted,
the .htpasswd authentication will not work %100!

I wrote this script to address an issue I had with Apache authentication and multiple load-balanced web servers, and I run it from a cronjob every so often.<br><br>
Basically I keep ONE copy of the relevent .htaccess files and NFS export their location to the other web servers in the cluster.<br><br>
I am sure this script could be extended further, but I have not messed with it since it serves the basic purpose I started towards. I hope someone else will find this code useful as well. ;)<br><br>
<b>UPDATE</b>:<br>
Added "use strict;" and found a missing semicolon at: <code>my $ip_add = "192.168.0.10"</code><br>
And a global <code>@mntargs;</code> hanging around.
