OPTIONS

-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 openser in the foreground (it doesn't 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/etc/openser/openser.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 openser will crash, the core file will be generated here.

-W method

Specify poll method.

-t chroot-dir

Forces openser to chroot after reading the config file.

-u uid

Changes the user id under which openser runs.

-g gid

Changes the group id under which openser runs.

-P pid-file

Creates a file containing the pid of the main openser process.

-i fifo-path

Creates a fifo, useful for monitoring openser status.

-x socket-path

Creates a unix socket, useful for monitoring openser status ( same as -i fifo-path but using unix sockets instead).
