Not much difference, really. I know I'm using the wrong tool, now. :-P
Somewhere between NOVELL.COM and LUGNET.COM, some router chokes on an initial
NNTP packet for about half a minute, after which it behaves just fine. No
problems with HTTP; haven't tried any other protocols, like FTP. That might
be a good comparison to NNTP, since it keeps a command session open...
