[I post this as it might be of general interest]
I've written a small program that monitors telnetd/rlogind on a SVR3.2 and
it should be easy to adapt it to monitor the finger port.
How it works:
- started by inetd instead of the usual daemon
- issues a gethostbyaddr and if it succeed a gethostbyname to check the
reverse mapping
- gives control to the system daemon (rlogind, telnetd or whatever you want).
- Administrator is free to choose any action if the DNS resolution fails.
For people interested, you can FTP anonymously the package at host
