Hello, not sure if i am going to be using the correct termanology, so if i
do not, please don't hit me.

I was wondering if there was a program out
there (preferably freeware) that does a good job of sniffing various ports
that some outside user would be 'listening' to or more importantly 'acting'
through. In other words, letting me know if i am the only one attuned to my
computers actions, perhaps constantly running in the background and if such
a 'breach' does take place, lets me know about it. I suppose the actual
preventing of that (if there is one) will come later, but i would just like
to know if it is happening. I could describe my situation in more detail,
but as i dont want to bore you all, i'll leave it at that. Thanks for any
help in advance, it is greatly appreciated.
