Modem Port Watch Dog (MPWD) is an authentication and session control tool. It secures dial-up ports as well as TCP/IP TELNET ports, and optionally enforces a Challenge/Response handshake to authenticate a user. Challenge/Response is the strongest authentication method currently available.

In addition to this main feature, MPWD supports these functions:

  • Trace of the entire terminal I/O to a disk file (key strokes)
  • Cleaning up inactive sessions
  • Support of generic users (= users known to MPWD only) and ID-hopping (you logon as yourself and get access to a functional user).
