Startup options

OpenSIPS can be started using the init scripts or opensipsctl utility. If you start OpenSIPS using the init scripts, you can stop it using only the init scripts. The same is valid if you start using the opensipsctl utility.

Starting, stopping, and restarting OpenSIPS using the init scripts is shown here:

/etc/init.d/opensips start|stop|restart

Starting, stopping, and restarting OpenSIPS using the opensipsctl utility is as follows:

opensipsctl start|stop|restart

The OpenSIPS executable has several start up options. These options allow you to change the configuration of the daemon. Some of the most useful are as follows:

• -C: To check the configuration file.
• -D -E -dddddd: To check the module loading. Don't use for production as it binds the first interface only.

There are lots of others that allow you to fine-tune your configuration. Check the following help line:

version: opensips 2.1.0dev-tls (i386/linux)
Usage: opensips -l address [-l address ...] [options]
Options:
 -f file Configuration file 
 -c Check configuration file for errors
 -C Similar to '-c' but checks the flags of exported
 functions from included route blocks
 -l address Listen on the specified address/interface [proto:]addr[:port], where proto=udp|tcp and
 addr= host|ip_address|interface_name. 
 -l udp:127.0.0.1:5080, -l eth0:5062.
 -n processes Number of child processes to fork per interface
 (default: 8)
 -r Use dns to check if is necessary to add a "received="
 field to a via
 -R Same as `-r` but use reverse dns;
 (to use both use `-rR`)
 -v Turn on "via:" host checking when forwarding replies
 -d Debugging mode (multiple -d increase the level)
 -D Do not fork into daemon mode
 -F Daemon mode, but leave main process foreground
 -E Log to stderr
 -T Disable tcp
 -N processes Number of tcp child processes 
 -W method poll method
 -V Version number
 -h This help message
 -b nr Maximum receive buffer size 
 -m nr Size of shared memory allocated in Megabytes
 -M nr Size of pkg memory allocated in Megabytes
 -w dir Change the working directory to "dir" (default "/")
 -t dir Chroot to "dir"
 -u uid Change uid
