matterircd

Minimal IRC server which integrates with mattermost and slack Tested on FreeBSD / Linux / Windows

Docker

Run the irc server on port 6667. You'll need to specify -bind 0.0.0.0:6667 otherwise it only listens on 127.0.0.1 in the container.

docker run -p 6667:6667 42wim/matterircd:latest -bind 0.0.0.0:6667

Now you can connect with your IRC client to port 6667 on your docker host.

FreeBSD

Install the port.

# pkg install matterircd

Or with a local ports tree.

$ cd /usr/ports/net-im/matterircd
# make install clean

Enable the service.

echo "matterircd_enable="YES" >> /etc/rc.conf

Copy the default configuration and modify to your needs.

# cp /usr/local/etc/matterircd/matterircd.toml.sample /usr/local/etc/matterircd/matterircd.toml

Start the service.

# service matterircd start

Compatibility

Matterircd works with slack and mattermost 5.x

Master branch of matterircd should always work against latest STABLE mattermost release.

Binaries

You can find the binaries here

Building

Go 1.8+ is required Make sure you have Go properly installed, including setting up your [GOPATH] (https://golang.org/doc/code.html#GOPATH)

cd $GOPATH
go get github.com/42wim/matterircd

You should now have matterircd binary in the bin directory:

$ ls bin/
matterircd

Usage

Usage of ./matterircd:
  -bind string
        interface:port to bind to. (default "127.0.0.1:6667")
  -conf string
        config file
  -debug
        enable debug logging
  -interface string
        interface to bind to (deprecated: use -bind)
  -mminsecure
        use http connection to mattermost
  -mmserver string
        specify default mattermost server/instance
  -mmskiptlsverify
        skip verification of mattermost certificate chain and hostname
  -mmteam string
        specify default mattermost team
  -port int
        Port to bind to (deprecated: use -bind)
  -restrict string
        only allow connection to specified mattermost server/instances. Space delimited
  -tlsbind string
        interface:port to bind to. (e.g 127.0.0.1:6697)
  -tlsdir string

Matterircd will listen by default on localhost port 6667. Connect with your favorite irc-client to localhost:6667

For TLS support you'll need to generate certificates.
You can use this program generate_cert.go to generate key.pem and cert.pem

Config file

See matterircd.toml.example
Run with matterircd -conf matterircd.toml

Mattermost user commands

/msg mattermost login <server> <team> <username/email> <password>

/msg mattermost login <server> <team> <username/email> token=<yourpersonaltoken>

Or if it is set up to only allow one host:

/msg mattermost login <username/email> <password>

/msg mattermost search query

Scrollback

/msg mattermost scrollback <channel> <limit>
e.g. /msg mattermost scrollback #bugs 100 shows the last 100 messages of #bugs

Slack user commands

Get a slack token on https://api.slack.com/custom-integrations/legacy-tokens

/msg slack login <token>

Or use team/login/pass to login

/msg slack login <team> <login> <password>

After login it'll show you a token you can use for the token login

Docker

A docker image for easily setting up and running matterircd on a server is available at docker hub.
