Etckeeper is a useful tool to store /etc in a version control system. It allows you to read the changes that have been made to the files in /etc, document these changes and recover a previous version of a modified file in case we made some changes that we don’t want to keep. It’ s a great system to control your server and find very quickly solutions.
Its installation is very trivial:
1 | aptitude install etckeeper |
If you want to enable CGI support for you domain or subdomain.
Install Apache2 mod-perl module:
1 | aptitude install libapache2-mod-perl2 |
Add this to the Apache configuration:
1 2 3 4 | <directory "="" var="" www="" domain="" cgi-scripts"=""> Allow from all Options All FollowSymLinks MultiViews </directory> |
Only scripts in directory /var/www/cgi-scripts can be executed as CGI.
