No, it could be any kind of server at all:
telnet, ftp, http, irc, nntp, smtp, pop, etc... any
single one, or any combination... assuming you're
running a 'nix, that is. In DOS, you could probably
only run a single server at a time.

Yes, BUT being on a 'LAN' the way you are, it's a
simple matter for the administrator to block whatever
kind of incoming packets he decides. IOW, if your ISP
decides he doesn't want you running a web server, it's
a simple matter to block incoming www traffic.
So in your case, it depends on how your upstream
sysadmin has things set up.

I'm not sure of the complete capability of the haXor
dOOdz. I suspect there are exploits into DOS machines,
but even if they couldn't gain access to the contents
of your hard drive, they certainly can run packet
sniffers to monitor everything that leaves or enters
your machine.
The whole reason that telnet, ftp, and rlogin are
falling out of favor is because passwords are sent in
the clear, thereby easily sniffed by these guys.
This is also the reason you should never send a credit
card number via insecure web pages, or e-mail. Their
packet sniffers are going to be looking for patterns
of XXXX-XXXX-XXXX-XXXX or XXXX XXXX XXXX XXXX or
XXXXXXXXXXXXXXXX where X is a digit.
You can send credit card info via e-mail pretty
safely if you cloak it. IOW "five-3-seven-oh then
1234, next comes eight forty-3 5, and finally 27-fifty-
three. Valid through the end of June next year"
Any human with half a brain can "translate" that to
its proper format, while a pattern-matching routine
capable of flagging that would have to be of
governmental proportions.
