This is my very first post here.
I've started my own project here at work to give hard proof to others that protocols such as ftp and telnet are very insecure. I am having a hard time trying to give real life examples of what could happen because any sort of sniffing I've done has been inside the network. I've taken a beginner's course on security which we touched a few basic parts of wireshark and cain/abel. I've been able to sniff my telnet/ftp traffic on my workstation and see everything in clear text but I just cant seem to figure out how I could sniff the traffic of a remote machine (on a switched network). What would be ideal is if I could somehow sniff the traffic from my house and show that everything is in complete clear text. Could someone point me in the right direction? I know many tools require command line and I am very familiar with that as I am the *NIX administrator here.
