JANUS(1) General Commands Manual JANUS(1) NAME janus - WebRTC server/gateway SYNOPSIS janus [options] DESCRIPTION janus is a WebRTC server/gateway developed by Meetecho conceived to be a general purpose one. As such, it doesn't provide any functionality per se other than implementing the means to set up a WebRTC media com- munication with a browser or application, exchanging JSON messages with it over different transports, and relaying RTP/RTCP and messages be- tween clients and the server-side application logic they're attached to. Any specific feature/application is provided by server side plug- ins, that browsers can then contact via the server to take advantage of the functionality they provide. Example of such plugins can be imple- mentations of applications like echo tests, conference bridges, media recorders, SIP gateways and the like. The reason for this is simple: we wanted something that would have a small footprint (hence a C implementation) and that we could only equip with what was really needed (hence pluggable modules). That is, some- thing that would allow us to deploy either a full-fledged WebRTC server on the cloud, or a small nettop/box to handle a specific use case. OPTIONS -h, --help Print help and exit -V, --version Print version and exit -b, --daemon Launch Janus in background as a daemon (default=off) -p, --pid-file=path Open the specified PID file when starting Janus (default=none) -N, --disable-stdout Disable stdout based logging (default=off) -L, --log-stdout Log to stdout, even when the process is daemonized (default=off) -L, --log-file=path Log to the specified file (default=stdout only) -H, --cwd-path=path Working directory for Janus daemon process (default=/) -i, --interface=ipaddress Interface to use (will be the public IP) -P, --plugins-folder=path Plugins folder (default=./plugins) -C, --config=filename Configuration file to use -F, --configs-folder=path Configuration files folder (default=./conf) -c, --cert-pem=filename DTLS certificate -k, --cert-key=filename DTLS certificate key -K, --cert-pwd=text DTLS certificate key passphrase (if needed) -S, --stun-server=address:port STUN server(:port) to use, if needed (e.g., Janus behind NAT, default=none) -1, --nat-1-1=ips Comma-separated list of public IPs to put in all host candi- dates, assuming a 1:1 NAT is in place (e.g., Amazon EC2 in- stances, default=none) -2, --keep-private-host When nat-1-1 is used (e.g., Amazon EC2 instances), don't remove the private host, but keep both to simulate STUN (default=off) -E, --ice-enforce-list=list Comma-separated list of the only interfaces to use for ICE gath- ering; partial strings are supported (e.g., eth0 or eno1,wlan0, default=none) -X, --ice-ignore-list=list Comma-separated list of interfaces or IP addresses to ignore for ICE gathering; partial strings are supported (e.g., vm- net8,192.168.0.1,10.0.0.1 or vmnet,192.168., default=vmnet) -6, --ipv6-candidates Whether to enable IPv6 candidates or not (default=off) -O, --ipv6-link-local Whether IPv6 link-local candidates should be gathered as well (default=off) -l, --libnice-debug Whether to enable libnice debugging or not (default=off) -f, --full-trickle Do full-trickle instead of half-trickle (default=off) -I, --ice-lite Whether to enable the ICE Lite mode or not (default=off) -T, --ice-tcp Whether to enable ICE-TCP or not (warning: only works with ICE Lite) (default=off) -Q, --min-nack-queue=number Minimum size of the NACK queue (in ms) per user for retransmis- sions, no matter the RTT -t, --no-media-timer=number Time (in s) that should pass with no media (audio or video) be- ing received before Janus notifies you about this -W, --slowlink-threshold=number Number of lost packets (per s) that should trigger a 'slowlink' Janus API event to users (default=0, feature disabled) -r, --rtp-port-range=min-max Port range to use for RTP/RTCP -B, --twcc-period=number How often (in ms) to send TWCC feedback back to senders, if ne- gotiated (default=200ms) -n, --server-name=name Public name of this Janus instance (default=MyJanusInstance) -s, --session-timeout=number Session timeout value, in seconds (default=60) -m, --reclaim-session-timeout=number Reclaim session timeout value, in seconds (default=0) -d, --debug-level=1-7 Debug/logging level (0=disable debugging, 7=maximum debug level; default=4) -D, --debug-timestamps Enable debug/logging timestamps (default=off) -o, --disable-colors Disable color in the logging (default=off) -M, --debug-locks Enable debugging of locks/mutexes (very verbose! default=off) -a, --apisecret=randomstring API secret all requests need to pass in order to be accepted by Janus (useful when wrapping Janus API requests in a server, none by default) -A, --token-auth Enable token-based authentication for all requests (default=off) -e, --event-handlers Enable event handlers (default=off) -w, --no-webrtc-encryption Disable WebRTC encryption, so no DTLS or SRTP (only for debug- ging!) (default=off) EXAMPLES janus - Launch Janus with all options from configurations files janus -b -L /tmp/januslog - Launch Janus as a daemon and log to the specified file janus -6 - Launch Janus with IPv6 support enabled janus -f - Launch Janus with full-trickle enabled BUGS If you think you found a bug or want to contribute a feature, you can issue or a pull request on https://github.com/meetecho/janus-gate- way/issues. Anyway, before doing that make sure you read the documentation at https://janus.conf.meetecho.com/docs/ and that it has not been dis- cussed already at https://janus.discourse.group/. We only use Github for code issues, and NOT for configuration or usage issues: use the group for that.
