Nessus is a security scanner
http://www.nessus.org. I was able to install both NMAP and Nessus on the SME 6b2 box, but needed to install several RPM's to get it to compile, such as gcc, flex, bison and several others. I do not have the list in front of me, or any type of howto at this time. I used the Windows Nessus client NessusWX (
http://www.nessus.org/related/index.html ). and I am able to connect to the Nessus Server and run security scans on internal and well as Internet sites. The Inprotect Project is a webbased front end to Nessus and thought it would be a nice project. You can have clients or potential clients use this tool and show them what a security guru you are and possible receive revenue by repairing their Internet Holes and vulnerabilities.
