I was testing a mail server today by telnetting to it, and a young employee was shocked that you could do that. It made me feel like I was 60+ years old!
@nixCraft Reminds me of the time I was over at the SGI office in the late 1990's. We needed to access the Indigo workstations in the departmental computer lab on campus. I first telneted into the Linux server, and then over to the SGIs. The fellow was totally shocked that one could do this. Of course, these days s/telnet/ssh/.
