Frank wrote in to tell us “IBM has released IP Security Validator, which enables independent evaluation of VPN configurations and quick/autonomous reaction to problems. An offline mode even allows the offline evaluation of traffic that was captured into a file with other tools such as tcpdump or pcapture. This way, traffic collected from non-Linux network nodes can be evaluated on a Linux machine.” The site goes on to say that among the features, it “reports the results on the standard output in words.” Finally, not only can I compete with my friends who use all Windows 2000 networks, I can read the results without a man page!
