Binaries

You can find the binaries here

Building

Go 1.14+ is required

go get github.com/42wim/matterircd

You should now have matterircd binary in the bin directory:

$ ls ~/go/bin/
matterircd

Config file

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

Usage

Usage of ./matterircd:
      --bind string      interface:port to bind to, or a path to bind to a Unix socket. (default "127.0.0.1:6667")
      --conf string      config file (default "matterircd.toml")
      --debug            enable debug logging
      --tlsbind string   interface:port to bind to. (e.g 127.0.0.1:6697)
      --tlsdir string    directory to look for key.pem and cert.pem. (default ".")
      --version          show version

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

Mattermost user commands

Login with user/pass

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

Login with personal token

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

Search

/msg mattermost search query

Scrollback

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

Mark messages in a channel/from a user as read (when DisableAutoView is set).

/msg mattermost updatelastviewed <channel>
/msg mattermost updatelastviewed <username>

Slack user commands

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

Login

/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.

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

FAQ

mattermost login with sso/gitlab

You'll need to get the MMAUTHTOKEN from your cookies, login via the browser first.
Then in chrome run F12 - application - Storage/cookies - select your mattermostdomain and fetch the MMAUTHTOKEN

Now login with /msg mattermost login <username> MMAUTHTOKEN=<mytoken>

See https://github.com/42wim/matterircd/issues/29 for more information

Also see #98 for a script that fetches it for you.

slack sso login / xoxc tokens

Taken from: https://github.com/insomniacslk/irc-slack

Log via browser on the Slack team, open the browser's network tab in the developer tools, and look for an XHR transaction. Then look for the token (it starts with xoxc-) in the request data the auth cookie, contained in the d key-value in the request cookies (it looks like d=XXXX;)

Then concatenate the token and the auth cookie using a | character, like this:

xoxc-XXXX|d=XXXX; and use the above as your token with slack login

/msg slack login xoxc-XXXX|d=XXXX;
