    longDescription = ''
      Wietse Venema's network logger, also known as TCPD or LOG_TCP.
      These programs log the client host name of incoming telnet, ftp,
      rsh, rlogin, finger etc. requests.  Security options are: access
      control per host, domain and/or service; detection of host name
      spoofing or host address spoofing; booby traps to implement an
      early-warning system.  The current version supports the System
      V.4 TLI network programming interface (Solaris, DG/UX) in
      addition to the traditional BSD sockets.
