This is a simple chat server written in Go. It is a work in progress, and is mainly meant as a toy to help me learn Go.
To use:
go get github.com/n0ot/chatsrvgo install github.com/n0ot/chatsrv/chatsrv_cmd- Create a directory ".chatsrv" in your home directory, and copy chatsrv_cmd/example.conf to $HOME/.chatsrv/conf; modify it to your liking.
- Create a file in $HOME/.chatsrv, called motd, with any text you want to be displayed when users connect.
- Run
chatsrv_cmd
To connect, use netcat:
nc localhost 36362
If you want to use tls, set useTls = true in the configuration, and point certFile and keyFile at your certificate and private key. Ncat is an improved version of netcat that supports ssl. To connect to a host with ssl, use
ncat --ssl localhost 36362
In order to prevent man-in-the-middle attacks, the certificate should be verified. If your certificate was signed by a trusted CA, you can just run
ncat --ssl-verify chatsrv.example.com 36362
Otherwise, you'll need to give the certificate (not the private key) to people who want to connect, and they'll need to type
ncat --ssl-verify --ssl-trustfile yourcert.pem chatsrv.example.com 36362
When chatting with ncat, input text and messages from the server can get mingled, and you will see your message twice--the copy echoed from your keyboard, and the response from the server. This renders ncat almost useless for actual conversations. If you want a better experience, get a mud client. Chatsrv has been tested with MUSHclient (requires stunnel or an ncat pipe for TLS) and TinyFugue.
Commands are:
/users: Says who's on the server/rooms: Lists the rooms on the server/whois [nick]: Displays information about a user; displays information about yourself if nick is omitted./create <roomname> [<topic> [<roompass>]]: Create a room. If roompass is set, the room will be private until it is destroyed. Rooms are destroyed when everyone leaves./join <room> [<roompass>]: Joins a room. Use roompass if the room is private./leave [<reason>]: Leaves a room./nick <NewNick>: Changes your nick/me <action>: Emotes an action; try /me sits down/quit: Quit from the server.
