This reminds me (uh-oh, another neckbeard old-timer story) of the very early days of the ARPAnet when there about 20 nodes or so... Back then there were free guest accounts on all the systems (mostly TOPS-10 and TENEX systems along with some wierd one-off machines like the UCSB symbolic math system on a 360/65), and we (at HARV-10) had a hacker who'd come in and mess things up. So the sysadmin (Geoff Steckel) started a logging process that dumped all suspicious incoming telnet connections input to a local TTY (yes, a physical teletypewriter). We used to gather around the TTY when it started chattering, to watch the hacker at work. Geoff pretty quickly figured out what he was doing and patched our TOPS-10 monitor source.
