Server Snapshotter

More Tools. . .

We provide this tool for FREE! However, we would greatly appreciate your support so we can continue to develop more tools (online tools and downloadable tools). You can show your support by sharing / liking this tool on Facebook. You can also tweet this page to your Twitter followers and following us on Twitter.

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).
