NAME
tcpd - access control facility for internet services
DESCRIPTION
The tcpd program can be set up to monitor incoming requests for
telnet, finger, ftp, exec, rsh, rlogin, tftp, talk, comsat and
other services that have a one-to-one mapping onto executable
files.
Operation is as follows: whenever a request for service arrives,
the inetd daemon is tricked into running the tcpd program instead
of the desired server. tcpd logs the request and does some addi-
tional checks. When all is well, tcpd runs the appropriate server
program and goes away.
