OK, I am going to get technical and geeky again
I have been having some connectivity problems in buildings around work. I have some suspicious of what it could be, but I need to corroborate it. I know fluke has some good cable analyzers, and they can do the job I need, but....they are way expensive (over 2K)
So, I was thinking, there should be something more, maybe in the form of software, and with some luck it is even open sourced
I think the problems we are having are due to in one location because a rat is eating the cables inside the wall, in the other locations, because normal copper cat5 cable was used for outside cable, where temps go well below 32, and I have seen cat5 snap very easily because of low temps (not to mention this cabling is about 6 to 7 years old in that condition).
Also, probably there is a software that analyzes network bottlenecks, like broadcast traffic, where it is coming from, ports and all that so it can be easily used to troubleshoot network problem
