Ex. Say I have an open connection to 21 on a certain server, could I possibly monitor existing and further attempted connections?
I'm not sure of the legalities of this, but I'm pretty sure it's okay since I'm just watching and not attempting to gain access where it shouldn't be gained. I also don't know whether this thread belongs in this part of the forum, but it's the closest I could find. If I'm wrong in this, please let me know and I'll discontinue the thread immediately
