static char Usage[] = "Usage: turnserver [options]\n"
"Options:\n"
" -d, --listening-device <device-name> Listener interface device (NOT RECOMMENDED. Optional, Linux only).\n"
" -p, --listening-port <port> TURN listener port (Default: 3478).\n"
" Note: actually, TLS & DTLS sessions can connect to the \"plain\" TCP & UDP port(s), too,\n"
" if allowed by configuration.\n"
" --tls-listening-port <port> TURN listener port for TLS & DTLS listeners\n"
" (Default: 5349).\n"
" Note: actually, \"plain\" TCP & UDP sessions can connect to the TLS & DTLS port(s), too,\n"
" if allowed by configuration. The TURN server\n"
" \"automatically\" recognizes the type of traffic. Actually, two listening\n"
" endpoints (the \"plain\" one and the \"tls\" one) are equivalent in terms of\n"
" functionality; but we keep both endpoints to satisfy the RFC 5766 specs.\n"
" For secure TCP connections, we currently support SSL version 3 and\n"
" TLS versions 1.0, 1.1 and 1.2. For secure UDP connections, we support\n"
" DTLS version 1.\n"
" --alt-listening-port<port> <port> Alternative listening port for STUN CHANGE_REQUEST (in RFC 5780 sense, \n"
" or in old RFC 3489 sense, default is \"listening port plus one\").\n"
" --alt-tls-listening-port <port> Alternative listening port for TLS and DTLS,\n"
" the default is \"TLS/DTLS port plus one\".\n"
" -L, --listening-ip <ip> Listener IP address of relay server. Multiple listeners can be specified.\n"
" --aux-server <ip:port> Auxiliary STUN/TURN server listening endpoint.\n"
" Auxiliary servers do not have alternative ports and\n"
" they do not support RFC 5780 functionality (CHANGE REQUEST).\n"
" Valid formats are 1.2.3.4:5555 for IPv4 and [1:2::3:4]:5555 for IPv6.\n"
" --udp-self-balance (recommended for older Linuxes only) Automatically balance UDP traffic\n"
" over auxiliary servers (if configured).\n"
" The load balancing is using the ALTERNATE-SERVER mechanism.\n"
" The TURN client must support 300 ALTERNATE-SERVER response for this functionality.\n"
" -i, --relay-device <device-name> Relay interface device for relay sockets (NOT RECOMMENDED. Optional, Linux only).\n"
" -E, --relay-ip <ip> Relay address (the local IP address that will be used to relay the\n"
" packets to the peer).\n"
" Multiple relay addresses may be used.\n"
" The same IP(s) can be used as both listening IP(s) and relay IP(s).\n"
" If no relay IP(s) specified, then the turnserver will apply the default\n"
" policy: it will decide itself which relay addresses to be used, and it\n"
" will always be using the client socket IP address as the relay IP address\n"
" of the TURN session (if the requested relay address family is the same\n"
" as the family of the client socket).\n"
" -X, --external-ip <public-ip[/private-ip]> TURN Server public/private address mapping, if the server is behind NAT.\n"
" In that situation, if a -X is used in form \"-X ip\" then that ip will be reported\n"
" as relay IP address of all allocations. This scenario works only in a simple case\n"
" when one single relay address is be used, and no STUN CHANGE_REQUEST\n"
" functionality is required.\n"
" That single relay address must be mapped by NAT to the 'external' IP.\n"
" For that 'external' IP, NAT must forward ports directly (relayed port 12345\n"
" must be always mapped to the same 'external' port 12345).\n"
" In more complex case when more than one IP address is involved,\n"
" that option must be used several times in the command line, each entry must\n"
" have form \"-X public-ip/private-ip\", to map all involved addresses.\n"
" --no-loopback-peers Disallow peers on the loopback addresses (127.x.x.x and ::1).\n"
" --no-multicast-peers Disallow peers on well-known broadcast addresses (224.0.0.0 and above, and FFXX:*).\n"
" -m, --relay-threads <number> Number of relay threads to handle the established connections\n"
" (in addition to authentication thread and the listener thread).\n"
" If explicitly set to 0 then application runs in single-threaded mode.\n"
" If not set then a default OS-dependent optimal algorithm will be employed.\n"
" The default thread number is the number of CPUs.\n"
" In older systems (pre-Linux 3.9) the number of UDP relay threads always equals\n"
" the number of listening endpoints (unless -m 0 is set).\n"
" --min-port <port> Lower bound of the UDP port range for relay endpoints allocation.\n"
" Default value is 49152, according to RFC 5766.\n"
" --max-port <port> Upper bound of the UDP port range for relay endpoints allocation.\n"
" Default value is 65535, according to RFC 5766.\n"

" -a, --lt-cred-mech Use the long-term credential mechanism.\n"
" -z, --no-auth Do not use any credential mechanism, allow anonymous access.\n"
" -u, --user <user:pwd> User account, in form 'username:password', for long-term credentials.\n"
" Cannot be used with TURN REST API.\n"
" -r, --realm <realm> The default realm to be used for the users when no explicit\n"
" origin/realm relationship was found in the database.\n"
" Must be used with long-term credentials \n"
" mechanism or with TURN REST API.\n"
" --check-origin-consistency The flag that sets the origin consistency check:\n"
" across the session, all requests must have the same\n"
" main ORIGIN attribute value (if the ORIGIN was\n"
" initially used by the session).\n"
" -q, --user-quota <number> Per-user allocation quota: how many concurrent allocations a user can create.\n"
" This option can also be set through the database, for a particular realm.\n"
" -Q, --total-quota <number> Total allocations quota: global limit on concurrent allocations.\n"
" This option can also be set through the database, for a particular realm.\n"
" -s, --max-bps <number> Default max bytes-per-second bandwidth a TURN session is allowed to handle\n"

" that limit will be dropped or temporary suppressed\n"
" (within the available buffer limits).\n"
" This option can also be set through the database, for a particular realm.\n"
