URL for port tester

[RedEyes]

Hey everyone -- A while ago, I used to visit a web site that would test all ports on your system to test how secure your system is... Unfortunately I lost the URL... Does anyone know of a site where I can test the security of my RedHat box?

Thanks! :)

the best i seen is vulnerabilities.org (http://vulnerabilities.org/)

Vulernabilities.org has a full NESSUS scanner, which does a full NMAP scan as port of the process. Of course, you can do this yourself from another box using NMAP and NESSUS, but they seem to have some nonstandard NESSUS modules, because their NESSUS seems to scan for more stuff than what comes with the standard distribution of NESSUS. That's the cool thing about NESSUS -- it's extensible, you can add any modules to it you want or write your own.
