# Matrix Chat Setup
|
|
|
|
|
|
|
|
In this tutorial we're going to setup a private matrix chat server along with VoIP support for the element desktop client.
|
|
|
|
_Disclaimer:_ If you want this service to remain anonymous, make sure you at least keep [TOR between you and the service](../../opsec/sensitiveremotevshome/index.md) from the [VPS acquisition](../../opsec/anonymousremoteserver/index.md) to actual service usage.
|
|
|
|
## **Initial Setup**
|
|
|
|
First install the required packages:
|
|
|
|
|
|
apt install docker.io docker-compose
|
|
|
|
|
|
|
|
Then create the directories required:
|
|
|
|
|
|
mkdir /srv/matrix/data -p
|
|
chown -R 755 /srv/matrix/data
|
|
cd /srv/matrix
|
|
|
|
|
|
|
|
Then we'll create the docker-compose.yml file and the generateconfig.sh script:
|
|
|
|
|
|
[ nowhere.moe ] [ /dev/pts/1 ] [/srv/matrix]
|
|
→ cat docker-compose.yml
|
|
version: "3.3"
|
|
|
|
services:
|
|
synapse:
|
|
image: "matrixdotorg/synapse:latest"
|
|
container_name: "matrix_synapse"
|
|
ports:
|
|
- 8008:8008
|
|
volumes:
|
|
- "./data:/data" #it will look at the current directory where you save the file and look for the data folder inside
|
|
environment:
|
|
VIRTUAL_HOST: "m.nowhere.moe"
|
|
VIRTUAL_PORT: 8008
|
|
LETSENCRYPT_HOST: "m.nowhere.moe"
|
|
SYNAPSE_SERVER_NAME: "m.nowhere.moe"
|
|
SYNAPSE_REPORT_STATS: "yes"
|
|
coturn:
|
|
image: instrumentisto/coturn:latest
|
|
restart: unless-stopped
|
|
volumes:
|
|
- ./coturn/turnserver.conf:/etc/coturn/turnserver.conf
|
|
ports:
|
|
- 47160-47200:47160-47200/udp
|
|
- 3478:3478
|
|
- 5349:5349
|
|
networks:
|
|
- mybridge
|
|
networks:
|
|
mybridge:
|
|
driver: bridge
|
|
|
|
[ nowhere.moe ] [ /dev/pts/1 ] [/srv/matrix]
|
|
→ cat generateconfig.sh
|
|
#!/bin/bash
|
|
|
|
docker-compose run --rm -e SYNAPSE_SERVER_NAME=m.nowhere.moe -e SYNAPSE_REPORT_STATS=yes synapse generate
|
|
|
|
|
|
|
|
My matrix server will have the "m.nowhere.moe" domain name. The coturn config mentioned here is used for the VOIP support. Now let's generate the initial keys of the matrix server like so:
|
|
|
|
|
|
[ nowhere.moe ] [ /dev/pts/1 ] [/srv/matrix]
|
|
→ ./generateconfig.sh
|
|
Creating network "matrix_default" with the default driver
|
|
Creating network "matrix_mybridge" with driver "bridge"
|
|
Setting ownership on /data to 991:991
|
|
Creating log config /data/m.nowhere.moe.log.config
|
|
Generating config file /data/homeserver.yaml
|
|
Generating signing key file /data/m.nowhere.moe.signing.key
|
|
A config file has been generated in '/data/homeserver.yaml' for server name 'm.nowhere.moe'. Please review this file and customise it to your needs.
|
|
|
|
[ nowhere.moe ] [ /dev/pts/1 ] [/srv/matrix]
|
|
→ ls
|
|
coturn data docker-compose.yml docker-compose.yml.coturn generateconfig.sh m.nowhere.moe.conf.nginx
|
|
|
|
[ nowhere.moe ] [ /dev/pts/1 ] [/srv/matrix]
|
|
→ ls data -lash
|
|
total 20K
|
|
4.0K drwxr-xr-x 2 991 991 4.0K Jan 14 11:12 .
|
|
4.0K drwxr-xr-x 4 root root 4.0K Jan 4 13:50 ..
|
|
4.0K -rw-r--r-- 1 root root 1.3K Jan 14 11:12 homeserver.yaml
|
|
4.0K -rw-r--r-- 1 root root 694 Jan 14 11:12 m.nowhere.moe.log.config
|
|
4.0K -rw-r--r-- 1 root root 59 Jan 14 11:12 m.nowhere.moe.signing.key
|
|
|
|
|
|
|
|
Now that's done, we can edit the homeserver.yaml if you want to remove trust into the "matrix.org" keys for federation to make it a truly private server:
|
|
|
|
|
|
[ nowhere.moe ] [ /dev/pts/1 ] [/srv/matrix]
|
|
→ cat data/homeserver.yaml | grep server
|
|
|
|
trusted_key_servers:
|
|
- server_name: ""
|
|
|
|
|
|
|
|
Then we can edit the coturn config like so:
|
|
|
|
|
|
[ nowhere.moe ] [ /dev/pts/1 ] [/srv/matrix]
|
|
→ ls
|
|
coturn data docker-compose.yml docker-compose.yml.coturn generateconfig.sh m.nowhere.moe.conf.nginx
|
|
|
|
[ nowhere.moe ] [ /dev/pts/1 ] [/srv/matrix]
|
|
→ cat coturn/turnserver.conf
|
|
use-auth-secret
|
|
static-auth-secret=cuAWWAAWWAAWWAWADDWADWADWADWADWADWAWADDWADWWADWADDWADWDWoy
|
|
realm=m.nowhere.moe
|
|
listening-port=3478
|
|
tls-listening-port=5349
|
|
min-port=47160
|
|
max-port=47200
|
|
verbose
|
|
allow-loopback-peers
|
|
cli-password=cuAWWAAWWAAWWAWADDWADWADWADWADWADWAWADDWADWWADWADDWADWDWoy
|
|
external-ip=116.202.216.190
|
|
|
|
[ nowhere.moe ] [ /dev/pts/1 ] [/srv/matrix]
|
|
→ cat data/homeserver.yaml | grep turn
|
|
turn_uris: [ "turn:m.nowhere.moe?transport=udp", "turn:m.nowhere.moe?transport=tcp" ]
|
|
turn_shared_secret: "cuAWWAAWWAAWWAWADDWADWADWADWADWADWAWADDWADWWADWADDWADWDWoy"
|
|
turn_user_lifetime: 86400000
|
|
turn_allow_guests: true
|
|
|
|
|
|
|
|
|
|
Make sure the ports match the ones in the docker-compose.yml file, and the external IP is the one of your server:
|
|
|
|
|
|
[ nowhere.moe ] [ /dev/pts/1 ] [/srv/matrix]
|
|
→ curl ifconfig.me -4
|
|
116.202.216.190
|
|
|
|
|
|
|
|
Then we start the docker-compose:
|
|
|
|
|
|
[ nowhere.moe ] [ /dev/pts/1 ] [/srv/matrix]
|
|
→ docker-compose up -d
|
|
Creating matrix_coturn_1 ... done
|
|
Creating matrix_synapse ... done
|
|
|
|
|
|
|
|
Then we create the accounts like so:
|
|
|
|
|
|
[ nowhere.moe ] [ /dev/pts/1 ] [/srv/matrix]
|
|
→ docker container ls | grep matrixdot
|
|
134d440b1480 matrixdotorg/synapse:latest "/start.py" About a minute ago Up 25 seconds (healthy) 8009/tcp, 0.0.0.0:8008->8008/tcp, :::8008->8008/tcp, 8448/tcp matrix_synapse
|
|
|
|
[ nowhere.moe ] [ /dev/pts/1 ] [/srv/matrix]
|
|
→ docker exec -it 134 bash
|
|
root@134d440b1480:/#
|
|
[ nowhere.moe ] [ /dev/pts/1 ] [/srv/matrix]
|
|
→ docker exec -it 134 bash
|
|
|
|

|
|

|

|

|
|

|
|

|
|
|
|
root@134d440b1480:/# exit
|
|
exit
|
|
|
|
|
|
|
|
Then we make sure that we can access the matrix server via nginx:
|
|
|
|
|
|
[ nowhere.moe ] [ /dev/pts/1 ] [/srv/matrix]
|
|
→ cat /etc/nginx/sites-enabled/m.nowhere.moe.conf
|
|
server {
|
|
listen 443 ssl http2;
|
|
listen [::]:443 ssl http2;
|
|
|
|
# For the federation port
|
|
listen 8448 ssl http2;
|
|
listen [::]:8448 ssl http2;
|
|
|
|
server_name m.nowhere.moe;
|
|
|
|
ssl_certificate /etc/acme/certs/m.nowhere.moe/fullchain.cer;
|
|
ssl_certificate_key /etc/acme/certs/m.nowhere.moe/m.nowhere.moe.key;
|
|
|
|
location ~ ^(/_matrix|/_synapse/client) {
|
|
# note: do not add a path (even a single /) after the port in `proxy_pass`,
|
|
# otherwise nginx will canonicalise the URI and cause signature verification
|
|
# errors.
|
|
proxy_pass http://localhost:8008;
|
|
proxy_set_header X-Forwarded-For $remote_addr;
|
|
proxy_set_header X-Forwarded-Proto $scheme;
|
|
proxy_set_header Host $host;
|
|
|
|
# Nginx by default only allows file uploads up to 1M in size
|
|
# Increase client_max_body_size to match max_upload_size defined in homeserver.yaml
|
|
client_max_body_size 50M;
|
|
|
|
# Synapse responses may be chunked, which is an HTTP/1.1 feature.
|
|
proxy_http_version 1.1;
|
|
}
|
|
}
|
|
|
|
[ nowhere.moe ] [ /dev/pts/1 ] [/srv/matrix]
|
|
→ nginx -t
|
|
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
|
|
nginx: configuration file /etc/nginx/nginx.conf test is successful
|
|
|
|
|
|
|
|
Then we test that we can login from a matrix client (which can be installed inside a [whonix VM](../../opsec/whonixqemuvms/index.md)), let's use [element](https://element.io/download) because we want to be able to do voicecalls:
|
|
|
|
    
|
|
|
|
Here we will setup a secure backup password, that is a separate password, for end to end encryption purposes. Then you can do the following steps:
|
|
|
|
|
|
|
|
Make sure you log out of every unverified session:
|
|
|
|
 
|
|
|
|
You may need to log in and log out before being able to send messages so do that, then create the space along with the chatroom
