BTW, I as I mentioned earlier, I'm rereading "The Cuckoo's Egg", by Clifford Stoll. There's one part there where he's getting a bunch of printers, to copy the attacker's traffic. I was sitting there thinking why not connect to serial ports and have the computer log the traffic, instead of wasting all that paper. Way back in the 80s, which is the period this book is written about, I was connecting serial ports to data circuits for monitoring purposes. Easy to do. All you need is serial ports and those mini-computers generally had several. We even had dedicated test sets to capture data and display on 2 lines at a time, one for each direction, for full duplex connections. I saw serial printers used for monitoring big machines.
As have I and that's what he was using. Regardless saving to a file makes it easier to search and save paper. I don't know what he was using for hardware, but if a VAX, a spare DZ11 board would provide 8 serial ports. As it was, they were using a spare computer, running Unix, to watch for the guy. If they were already doing that, it wouldn't be hard to capture the data. BTW, that book's an excellent read. It can be found for free download on the Internet. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
