I have seen some ontopic books (UNIX, 10 years old now) that strongly
recommend disabling finger to prevent unauthorized types from finding
likely targets among the accounts. Since then, finger services (such as
cfingerd) have become less of an issue because you can limit some
information, but it's likely that the old maxim still holds, as well as
the new one: if you don't positively need it than don't turn it on. Too
bad, though: 'finger' was nice when you wanted to get an e-mail address
that you weren't certain of. (after the demise of finger in general
circulation I used to connect to port 25 and try a couple of vrfys-
can't do that anymore in most places, but it's a "legitimate" need for
port 25, right?)
apophis$
which finger
/bin/finger
apophis$ which talk
/bin/talk
...looks to me like they're still there.
Yes, actually try to use them across networks. There are these
funny little things on the outside of most organizations called
"firewalls", maybe you've heard of them.

So write one that doesn't give away the store. I did; it's just a Perl
script hooked up to inetd with some logging. finger is so simple it can
barely be considered a "protocol."

Yeah, and I just ran a Nessus scan against a web server at work,
and it recommended that I close port 80 because it's a potential
security risk. The only way the data on a machine is 100% secure is
if the machine is disconnected from the network, powered off, and
sitting in a closet. If one requires more usefulness than that
configuration provides, there is going to be some element of risk.
There's just no way around it.

This is why I personally recommend Comcast broadband.
