Ok - I've just managed to build cheops-ng from source on RedHat 9. Download this package:
http://belnet.dl.sourceforge.net/sou...-ng-0.1.12.tgz
Extract it:
tar -xzf cheops-ng-0.1.12.tgz
Move into that directory and start the configure proccess:
cd cheops-ng-0.1.12
./configure
Compile source (you may get some warnings but you an probably ignore them):
make
Install the app as root with:
make install
Then as root start the scanning agent:
cheops-agent
To start the program itself run:
cheops-ng
It seems to work ok for me.
