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 communication with a browser or application, exchanging JSON messages with it over dif- ferent transports, and relaying RTP/RTCP and messages between clients and the server-side application logic they're attached to. Any specific fea- ture/application is provided by server side plugins, that browsers can then contact via the server to take advantage of the functionality they provide. Example of such plugins can be implementations 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, something 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) --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) -R, --log-rotate-sig=signal Signal to trigger log reloading (e.g. SIGUSR1) (default=none) -l, --check-openfiles-limits=value Check if the current limit on the maximum number of allowed open file descriptors matches this value (if not, Janus will close with a failure; default=none) -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, de- fault=none) -1, --nat-1-1=ips Comma-separated list of public IPs to put in all host candidates, assuming a 1:1 NAT is in place (e.g., Amazon EC2 instances, de- fault=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 gather- ing; partial strings are supported (e.g., eth0 or eno1,wlan0, de- fault=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 (de- fault=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 retransmissions, no matter the RTT -t, --no-media-timer=number Time (in s) that should pass with no media (audio or video) being 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 negoti- ated (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; de- fault=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 debugging!) (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 speci- fied 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-gateway/issues. Anyway, before doing that make sure you read the documentation at https://janus.conf.meetecho.com/docs/ and that it has not been discussed already at https://janus.discourse.group/. We only use Github for code is- sues, and NOT for configuration or usage issues: use the group for that.
