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?)

...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.
