The Server Snapshotter app (serversnapshotter.cgi) is a CGI-Perl script which checks your server configuration including: environmental variables, server setup including server specs / Perl / Sendmail version and paths, and installed
Perl modules. To install and run the app on your web server, your server needs to be a Unix or related server running Apache. Server must have Perl version 5.004+ installed, and the File::Find Apache module must be installed.
1. Copy the code below into a file called serversnapshotter.cgi. If your server uses the .pl extension for CGI-Perl scripts, rename as serversnapshotter.pl.
2. Edit path to Perl at top of script if it differs on your server. The usual and default path is [/usr/bin/perl]. However, on some servers it may be /usr/local/bin/perl. If in doubt, then refer to a script on your server that does work,
or ask your web host.
3. FTP upload script to server in ASCII (text), and CHMOD as 755 (rwxr-xr-x).
