-h Displays a short usage description, including all available options. -c Checks the config file and displays the aliases and listen interface list. -C Similar to -c but in addition checks the flags of exported functions from included route blocks. -r Uses dns to check if it is necessary to add a "received=" field to a via. -R Same as -r but uses reverse dns. -v Turns on via host checking when forwarding replies. -d Turns on debugging, multiple -d increase the debug level. -D Runs opensips in the foreground (it doesnt fork into daemon mode). -E Sends all the log messages to stderr. -T Disables TCP support. -V Displays the version number. -f config-file Reads the configuration from config-file (default /usr/local/etc/opensips/opensips.cfg ). -l address Listens on the specified address/interface. Multiple -l mean listening on multiple addresses. The address format is [proto:]address[:port], where proto = udp|tcp and address = host|ip_address|interface_name. Example: -l localhost, -l udp:127.0.0.1:5080, -l eth0:5062. The default behaviour is to listen on all the ipv4 interfaces. -n processes-no Specifies the number of children processes forked per interface (default 8). -N tcp processes-no Specifies the number of children processes forked to handle tcp incoming connections (by default is equal to -n ). -b max_rcv_buf_size Maximum receive buffer size which will not be exceeded by the auto-probing procedure even if the OS allows. -m shared_mem_size Size of the shared memory which will be allocated (in Megabytes). -w working-dir Specifies the working directory. In the very improbable event that opensips will crash, the core file will be generated here. -W method Specify poll method. -t chroot-dir Forces opensips to chroot after reading the config file. -u uid Changes the user id under which opensips runs. -g gid Changes the group id under which opensips runs. -P pid-file Creates a file containing the pid of the main opensips process. -i fifo-path Creates a fifo, useful for monitoring opensips status. -x socket-path Creates a unix socket, useful for monitoring opensips status ( same as -i fifo-path but using instead unix sockets).
