About Lichat-TCP-Server

This is a simple, threaded, TCP-based server for the Lichat protocol.

How To

Create a new server instance and pass it whatever settings you would like.

(defvar *server* (make-instance 'lichat-tcp-server:server))

Notable initargs of potential interest are:

• :name The name the server goes by on its own network. Defaults to (machine-instance).
• :hostname The hostname to which the TCP listener should bind. The default is 0.0.0.0.
• :port The port the TCP listener should listen on. The default is 1111.
• :ping-interval The interval in which pings should be sent out to clients. The default is 60.
• :salt The salt with which passwords are hashed. The default is an empty string.
• :idle-timeout The number of seconds without a response from a client after which it is considered to have timed out. The default is 120.
• :flood-frame The size of a flood prevention frame. The default is 30.
• :flood-limit The number of allowed updates within a frame before flood limitation takes effect. The default is 40.
• :connection-limit The number of connections in total that the server supports before dropping incoming ones. The default is 100.

Once a server exists, it can be started to listen to incoming connections:

(lichat-tcp-server:open-connection *server*)

The server logs information via Verbose. If you set the REPL level to :trace you should see a bunch of status messages being printed every now and again.

Once you're done with the server, you can shut it down again.

(lichat-tcp-server:close-connection *server*)
