# Setting up Appservice IRC bridging (optional)
 | 
						|
 | 
						|
**Note**: bridging to [IRC](https://en.wikipedia.org/wiki/Internet_Relay_Chat) can also happen via the [Heisenbridge](configuring-playbook-bridge-heisenbridge.md) bridge supported by the playbook.
 | 
						|
 | 
						|
The playbook can install and configure the [matrix-appservice-irc](https://github.com/matrix-org/matrix-appservice-irc) bridge for you.
 | 
						|
 | 
						|
See the project's [documentation](https://github.com/matrix-org/matrix-appservice-irc/blob/master/HOWTO.md) to learn what it does and why it might be useful to you.
 | 
						|
 | 
						|
## Adjusting the playbook configuration
 | 
						|
 | 
						|
To enable the bridge, add the following configuration to your `inventory/host_vars/matrix.example.com/vars.yml` file:
 | 
						|
 | 
						|
```yaml
 | 
						|
matrix_appservice_irc_enabled: true
 | 
						|
 | 
						|
matrix_appservice_irc_ircService_servers:
 | 
						|
  irc.example.com:
 | 
						|
    name: "ExampleNet"
 | 
						|
    port: 6697
 | 
						|
    ssl: true
 | 
						|
    sasl: false
 | 
						|
    allowExpiredCerts: false
 | 
						|
    sendConnectionMessages: true
 | 
						|
    botConfig:
 | 
						|
      enabled: true
 | 
						|
      nick: "MatrixBot"
 | 
						|
      joinChannelsIfNoUsers: true
 | 
						|
    privateMessages:
 | 
						|
      enabled: true
 | 
						|
      federate: true
 | 
						|
    dynamicChannels:
 | 
						|
      enabled: true
 | 
						|
      createAlias: true
 | 
						|
      published: true
 | 
						|
      joinRule: public
 | 
						|
      groupId: +myircnetwork:localhost
 | 
						|
      federate: true
 | 
						|
      aliasTemplate: "#irc_$CHANNEL"
 | 
						|
    membershipLists:
 | 
						|
      enabled: false
 | 
						|
      floodDelayMs: 10000
 | 
						|
      global:
 | 
						|
        ircToMatrix:
 | 
						|
          initial: false
 | 
						|
          incremental: false
 | 
						|
        matrixToIrc:
 | 
						|
          initial: false
 | 
						|
          incremental: false
 | 
						|
    matrixClients:
 | 
						|
      userTemplate: "@irc_$NICK"
 | 
						|
      displayName: "$NICK (IRC)"
 | 
						|
      joinAttempts: -1
 | 
						|
    ircClients:
 | 
						|
      nickTemplate: "$DISPLAY[m]"
 | 
						|
      allowNickChanges: true
 | 
						|
      maxClients: 30
 | 
						|
      idleTimeout: 10800
 | 
						|
      reconnectIntervalMs: 5000
 | 
						|
      concurrentReconnectLimit: 50
 | 
						|
      lineLimit: 3
 | 
						|
```
 | 
						|
 | 
						|
### Extending the configuration
 | 
						|
 | 
						|
There are some additional things you may wish to configure about the bridge.
 | 
						|
 | 
						|
Take a look at:
 | 
						|
 | 
						|
- `roles/custom/matrix-bridge-appservice-irc/defaults/main.yml` for some variables that you can customize via your `vars.yml` file
 | 
						|
- `roles/custom/matrix-bridge-appservice-irc/templates/config.yaml.j2` for the bridge's default configuration. You can override settings (even those that don't have dedicated playbook variables) using the `matrix_appservice_irc_configuration_extension_yaml` variable
 | 
						|
 | 
						|
## Installing
 | 
						|
 | 
						|
After configuring the playbook, run it with [playbook tags](playbook-tags.md) as below:
 | 
						|
 | 
						|
<!-- NOTE: let this conservative command run (instead of install-all) to make it clear that failure of the command means something is clearly broken. -->
 | 
						|
```sh
 | 
						|
ansible-playbook -i inventory/hosts setup.yml --tags=setup-all,start
 | 
						|
```
 | 
						|
 | 
						|
The shortcut commands with the [`just` program](just.md) are also available: `just install-all` or `just setup-all`
 | 
						|
 | 
						|
`just install-all` is useful for maintaining your setup quickly ([2x-5x faster](../CHANGELOG.md#2x-5x-performance-improvements-in-playbook-runtime) than `just setup-all`) when its components remain unchanged. If you adjust your `vars.yml` to remove other components, you'd need to run `just setup-all`, or these components will still remain installed. Note these shortcuts run the `ensure-matrix-users-created` tag too.
 | 
						|
 | 
						|
## Usage
 | 
						|
 | 
						|
To use the bridge, you need to start a chat with `@irc_bot:example.com` (where `example.com` is your base domain, not the `matrix.` domain).
 | 
						|
 | 
						|
## Troubleshooting
 | 
						|
 | 
						|
As with all other services, you can find the logs in [systemd-journald](https://www.freedesktop.org/software/systemd/man/systemd-journald.service.html) by logging in to the server with SSH and running `journalctl -fu matrix-appservice-irc`.
 | 
						|
 | 
						|
### Configuring for logging
 | 
						|
 | 
						|
The default logging level for this component is `debug`, and the log is output to the console only. If you want to change the verbosity or enable logging to a file, add the following configuration to your `vars.yml` file (adapt to your needs) and re-run the playbook:
 | 
						|
 | 
						|
```yaml
 | 
						|
matrix_appservice_irc_configuration_extension_yaml: |
 | 
						|
  logging:
 | 
						|
    # Level to log on console/logfile.
 | 
						|
    # Valid values: error, warn, info, debug
 | 
						|
    level: "debug"
 | 
						|
    # The file location to log to. This is relative to the project directory.
 | 
						|
    logfile: "debug.log"
 | 
						|
    # The file location to log errors to. This is relative to the project directory.
 | 
						|
    errfile: "errors.log"
 | 
						|
```
