Conserver

conserver is a *nix program that allows easy control of access to console/terminal devices, and distributes this access on the LAN. It is composed of two programs - conserver, the daemon, and console, the client. The client can be run either on the local machine or over the network, and can connect to a console on the "master" server or any other subordinate server.

The conserver client has two modes - read-write (RW), known as "normal" mode, and read-only (RO), known as "spy" mode.
