<snip> > food for next mail : can tcpd work for UDP? No.
what kinds of servers can tcpd not protect?
Essentially, any server which is not called from tcpd will not be protectable. Hence, anything that runs standalone and forks children
to
handle requests (sendmail/apache, etc) cannot be protected by tcp wrappers.

tcpd can work for UDP also. There is no reason why not. A request comes in, tcpd validates it, and calls the appropriate executable. Also, why not mention smtp in the inetd configuration file for incoming requests, and call sendmail?(though that wont achieve much, but just for academic interest!) I'm not sure of NFS though..can tcpd keep track of sessions?dont think so.
