    Start listening to finger callbacks and call the given callback for
    each request. See AnyEvent::Finger::Server for details on the options
    and the callback.

CAVEATS

    Finger is an oldish protocol and almost nobody uses it anymore.

    Most finger clients do not have a way to configure an alternate port.
    Binding to the default port 79 on Unix usually requires root. Running
    AnyEvent::Finger::Server as root is not recommended.

    Under Linux you can use iptables to forward requests to port 79 to an
    unprivileged port. I was able to use this incantation to forward port
    79 to port 8079:

     # iptables -t nat -A PREROUTING -p tcp --dport 79 -j REDIRECT --to-port 8079
     # iptables -t nat -I OUTPUT -p tcp -d 127.0.0.1 --dport 79 -j REDIRECT --to-port 8079

    The first rule is sufficient for external clients, the second rule was
