This repo is a fork of fbridge.
If you log in to your facebook account from a browser, after you do, it's a good idea to restart fbridge-asyncio, since facebook might disconnect you.
Example service file for fbridge:
[Unit]
Description=fbridge-asyncio
Requires=matterbridge.service
After=matterbridge.service
[Service]
WorkingDirectory=/home/user/fbridge-asyncio
ExecStart=/usr/bin/python3 /home/user/fbridge-asyncio/fbridge_asyncio.py
KillSignal=SIGINT
Restart=always
[Install]
WantedBy=multi-user.target
Example service file for matterbridge:
[Unit]
Description=matterbridge
[Service]
ExecStart=/home/user/matterbridge/matterbridge-1.20.0-linux-armv6 -conf /home/user/matterbridge/matterbridge.toml
Restart=always
[Install]
WantedBy=multi-user.target
Warning if User= is not specified, these services will run everything as root, which you might not want.
Example config for fbridge:
# You have to set a RemoteNickFormat in "matterbridge.toml", otherwise the bot won't work properly.
# This is used so that messages written in the api, don't echo back.
# Also this approach allows you to write through the user which is the bot in Facebook.
# It has to be the same format you set in "matterbridge.toml" for the api.
# This has to be a regular expression, if you don't know how, just use the default here, but you have to
# set the RemoteNickFormat for the bridges you'll be receiveing from into the api in matterbridge.toml
# as "[{PROTOCOL}] <{NICK}>"
RemoteNickFormat = '''\[(\w+)\]\s<.+>'''
# These links are hosted by the matterbridge api after configuring it.
stream_api_url = "http://localhost:4242/api/stream" # Stream messages from api
message_api_url = "http://localhost:4242/api/message" # Send message to api
messages_api_url = "http://localhost:4242/api/messages" # Receive messages from api
websocket_api_url = "ws://localhost:4242/api/websocket" # Receive messages from api
# With stream matterbridge doesn't seem to repond after the fbridge-asyncio script is restarted, but
# uses normal streaming, the messages mode is a hack sorta, which avoids this problem.
# Maybe I'm stupid, but idk, this is what I came up with. If you want to restart the script,
# without needing to restart matterbridge, use the messages or websocket mode.
# Websocket should in theory be the best choice.
listen_api_mode = "websocket" # or "stream" or "messages"
# The domain from which you got the cookie.
cookie_domain = "messenger.com"
# How fast to restart the script in case facebook randomly stops sending.
timeout_listen = 3600
# This section is used so that the script knows which thread to relay to which gateway in matterbridge.
[threads]
[threads.1567891234567891] # Here you put the thread id you got from the url in messenger.com
gateway = "gateway1" # This is the gateway you've configured in matterbridge for the api.
# This section is used so that the script knows what name to be set, to each user id, otherwise in the RemoteNickFormat
# it will just echo the user ids.
[users]
[users.100012345678912] # Here you put the user id you got from the url in messenger.com
username = "First Last"
[users.100012345678913]
username = "John Johnson"
[users.100012345678914]
username = "Perry Platapus"This config needs to be called fbridge-config.toml! Without this file the script won't run.
- matterbridge
- Python 3 (preferably 3.9+)
- pip
To install the required modules, run in the directory that requirements.txt is present for fbridge-asyncio:
python -m pip install -r requirements.txt
If just python doesn't work, try running python3, the same goes for pip and pip3.
This will install modules globally.
If you don't wish to add bloat to your setup, checkout the venv docs.
Read around in the repo for fbchat-asyncio to get familiar with it, otherwise you'll have a hard time logging in. This is the module that's used for communicating with the Facebook chat.
If in other services (example: discord) there is a way to set any username, someone can impersonate another user by accident or not. That's why if you're bridging small groups and using other bots it's a good idea to handle the duplicates with a "tengo" script in matterbridge. Some services like mumble (registration) and irc (nickserv) have mechanisms to reserve usernames, but if it's not configured you can still use the script.
You can create a file called "userids.tengo" in the directory where your matterbridge config is with the following code:
userids := {"123456789123456789": "some_username",
"otheruser@some-hostanme.new": "otheruser"}
for key, res in userids {
if key == msgUserID {
result=res
break
} else {
/*
Ignoring the facebook bridge, set "fb" to your bridge name.
This is done for fbridge-asyncio since it already uses the user id.
*/
if bridge != "fb" && protocol != "api" {
result=nick + " | not static"
} else {
result=nick
}
}
}
Then add this to your matterbridge config file:
[tengo]
RemoteNickFormat="userids.tengo"
If you're running matterbridge as a service, set the full path for "userids.tengo" in the config.
and replace all {NICK} with {TENGO}.
You should consider encrypting your config files especially the session.json file.
Anyone who can plug in a USB drive with a live OS running on it to your computer even without a password can get access to the data on the device unless you encrypt the whole drive or data. With a Raspberry Pi all they need is the SD card and a reader.
This script may need your actual session which would allow anyone else to use it as well, so if you have a session file stored, it's highly recommended looking at the following.
On Windows, for whole drive encryption you can use the "BitLocker" tool.
There is also the file encryption which you can do by opening "Properties" of any file, then "Advanced...", finally "Encrypt contents to secure data".
You can also look at open source options for encryption on Windows, such as:
-
7-Zip (https://www.7-zip.org/), for encrypting archives.
-
Gpg4win (https://www.gpg4win.org/), for an OpenPGP implementation for Windows.
For GPG checkout info bellow.
On Linux, for whole drive encryption you can use dm-crypt (https://wiki.archlinux.org/title/Dm-crypt).
One possible solution for Linux if whole drive encryption isn't really an option (for example on Raspberry Pi), or you just don't want to encrypt the whole drive:
Install GPG: https://gnupg.org/
Make sure /tmp is mounted as tmpfs: https://wiki.archlinux.org/title/Tmpfs#Examples
After installing GPG, create a key: https://wiki.archlinux.org/title/GnuPG#Create_a_key_pair
Keep in mind, not using a strong password is a bad idea since brute forcing the password of a private key is very possible and only thing protecting it is the password itself. If anyone can get to the drive and is able to brute force they have the private key in plain sight since it's just a simple file with gibberish in it.
Run: gpg --list-keys
Then copy the fingerprint of your key (example: 9D2FAD842D83E3CB13313334190C37B0F8665DA8).
Encrypt the files using this command:
gpg -r FINGERPRINT_HERE -o session.json.gpg -e session.json &&
gpg -r FINGERPRINT_HERE -o fbridge-config.toml.gpg -e fbridge-config.toml
Then you can create a script like this (make sure to replace the paths and usernames with yours):
#!/bin/bash
gpg -o /tmp/fbridge-config.toml -d /path/to/YOUR/fbridge-config.toml.gpg &&
gpg -o /tmp/session.json -d /path/to/YOUR/session.json.gpg &&
sudo chown YOURusername:YOURusername /tmp/fbridge-config.toml &&
sudo chown YOURusername:YOURusername /tmp/session.json &&
sudo chmod 600 /tmp/fbridge-config.toml &&
sudo chmod 600 /tmp/session.json
Then when you run this script and type your password the decrypted files will
be in the /tmp directory which is only in RAM and will be cleared on shutting down.
The permissions are set so that only your user can read/write the files when the machine is on.
Create session.toml where the script is and place in it:
path = "/tmp/session.json"
Now you can delete the old "session.json" if you have one where the script is.
Then clean fbridge-asyncio.toml and only type in it:
path = "/tmp/fbridge-config.toml"
This will tell the script where to look for the files.
Don't forget to run the decryption script on every boot.
