Hi everyone,
I wonder anyone of you you could tell me how to obtain
a complete of telnet numbers of this world.
Also, could you please give me some "interesting" numbers
which I could login as guest and browse around? 8^)
Thanx in advance.

Think I'll go shut down inetd.... and while I'm at it, log sendmail to hades and back.... Anybody who gives out hints like this deserves what s/he gets. -- Glenn R.

There are quite a few Internet Bulletin boards for example -- a list has
been posted recently in some newsgroup, maybe comp.misc; also have a
look at the NIXPUB posting there, some of the sites are on the internet.
As to browsing around, I think that anonymous FTP is amply sufficient,
and highly reawrding in terms of the mass of useful, free sw that you
can get. I would encourage anybody, especially people learning
programming, to browse around anonymous FTP sites. Looking at and
installing other, presumably more accomplished, programmers' code is one
of the best educational experiences.

If a site has guest accounts for telnet, they are offering a public
service, ust like an anonymous account for ftp. If a site has
"involuntary" guest accounts their sysadmins are not doing their job too
well.
If a site has serious security needs and runs stock workstations with
stock Unixes and utilities with stock warranties they are not showing
due diligence at best, and deceiving their management at worst.
Remember: when you are on the internet you cannot really distinguish
between local and worldwide access. Security, as somebody recently so
appropriately remembered, is a host, not a network issue.
