Directories mappings

• /opt/janus/lib/janus -> $SNAP/opt/janus/lib/janus
• /opt/janus/share/janus/streams-> $SNAP/opt/janus/share/janus/streams
• /opt/janus/etc/janus -> $SNAP_COMMON/etc
• /opt/janus/share/janus/recordings -> $SNAP_COMMON/share/recordings
• /opt/janus/share/janus/demos/voicemail -> $SNAP_COMMON/share/voicemail

So you can find:

• Configs in /var/snap/janus-gateway/common/etc (i.e. $SNAP_COMMON/etc)
• Recordings in /var/snap/janus-gateway/common/share/recordings (i.e. $SNAP_COMMON/share/recordings)
• Voicemail in /var/snap/janus-gateway/common/share/voicemail (i.e. $SNAP_COMMON/share/voicemail)

Some hints

• Install Janus latest stable snap: sudo snap install janus-gateway;
• Install Janus edge snap (i.e. built from latest master): sudo snap install janus-gateway --edge;
• View Janus log: sudo snap logs janus-gateway;
• View Janus log and wait for new lines: sudo snap logs janus-gateway -f;
• Janus snap restart (required after configs edit): sudo snap restart janus-gateway;

Getting Started Guide

1. sudo apt update
2. sudo apt install snapd
3. Do you need data channel support?

• Y: stable doesn't have it. See this discussion. If you can deal with daily restarts (e.g., just local testing), then sudo snap install janus-gateway --edge will have it. For prod environments, either switch it to dev mode to stop updates, or create your own snap.
• N: sudo snap install janus-gateway

4. Use logs to check if it's running. Many options:

• snap list janus-gateway
• sudo snap logs janus-gateway
• sudo snap logs janus-gateway -f
• sudo snap logs janus-gateway -n=all
• sudo systemctl status snap.janus-gateway.janus-gateway.service

5. Use sudo lsof -i -P -n | grep janus to check ports being listened to
6. Open /var/snap/janus-gateway/common/etc to view/modify configs
7. Run the demos locally: cd /snap/janus-gateway/current/opt/janus/share/janus/demos && python -m SimpleHTTPServer 8000
8. Then visit http://localhost:8000 in your browser.
