对linux环境中tty设备的监听，实现对终端访问的监控。-ttywatch was originally designed to log serial console output from lots of Linux machines on a single monitor machine. It:



Handles log rotation correctly.

Can be configured in both a configuration file and on the command line (mix-and-match command-line and config file). The config file language is the same as the command-line language　learn one and you know both. Any configuration that can be specified on the command line can be specified in exactly the same way in a configuration file, and vice versa.

Supports arbitrary data logging methods via dynamically loaded modules.

Can optionally connect any monitored port to a network socket, and it can support arbitrarily many telnet connections to each port. The connections work together in "whiteboard" fashion　all output is shown to every connection and input is accepted from all connections.

Can connect to network ports speaking the telnet protocol as well as to serial ports　this allows ttywatch instances to be cascaded. For exa
