Gospy-applet is a Gnome applet that monitors changes on servers and web pages. You can add an illimited number of sources to monitor. It is possible to detect changes in HTTP header fields, IP associated with domain name, page content, page status, page load time and so on.
First we need to install (at least) these dependencies :
sudo apt-get install libgtk2.0-dev libwnck-dev libpanel-applet2-dev libgnet-dev libesmtp-dev libssl-dev
then run the classic :
./configure --prefix=/usr make sudo make install
Important : logout/in your gnome session before you start using gospy.
