[sr-dev] what is the difference between the ser and sercmd

Hi all with the help from Henning Westerholt, i install sip-router successfull i just wonder there are 2 command ser sercmd what is the difference between them Thank you Ha` debian:/usr/local/etc/ser# ser -h version: ser 2.1.0-dev23-make (i386/linux) Usage: ser [options] Options: -f file Configuration file (default: /usr/local/etc/ser/ser.cfg) -L path Modules search path (default: /usr/local/lib/ser/modules:/usr/local/lib/ser/modules_s:/usr/local/lib/ser/modules_k) -c Check configuration file for errors -l address Listen on the specified address/interface (multiple -l mean listening on more addresses). The address format is [proto:]addr_lst[:port], where proto=udp|tcp|tls|sctp, addr_lst= addr|(addr, addr_lst) and addr= host|ip_address|interface_name. E.g: -l locahost, -l udp:127.0.0.1:5080, -l eth0:5062, -l "sctp:(eth0)", -l "(eth0, eth1, 127.0.0.1):5065". The default behaviour is to listen on all the interfaces. -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 no 1..do not fork (almost) anyway, 2..do not daemonize creator 3..daemonize (default) -E Log to stderr -T Disable tcp -N Number of tcp child processes (default: equal to `-n') -W poll method -V Version number -h This help message -b nr Maximum receive buffer size which will not be exceeded by auto-probing procedure even if OS allows -m nr Size of shared memory allocated in Megabytes -w dir Change the working directory to "dir" (default: "/") -t dir Chroot to "dir" -u uid Change uid -g gid Change gid -P file Create a pid file -G file Create a pgid file -O nr Script optimization level (debugging option) debian:/usr/local/etc/ser# sercmd -h version: sercmd 0.1 Usage: sercmd [options][-s address] [ cmd ] Options: -s address unix socket name or host name to send the commands on -R name force reply socket name, for the unix datagram socket mode -D dir create the reply socket in the directory <dir> if no reply socket is forced (-R) and a unix datagram socket is selected as the transport -f format print the result using format. Format is a string containing %v at the places where values read from the reply should be substituted. To print '%v', escape it using '%': %%v. -v Verbose -V Version number -h This help message address: [proto:]name[:port] where proto is one of tcp, udp, unixs or unixd e.g.: tcp:localhost:2048 , unixs:/tmp/ser_ctl cmd: method [arg1 [arg2...]] arg: string or number; to force a number to be interpreted as string prefix it by "s:", e.g. s:1 Examples: sercmd -s unixs:/tmp/ser_unix system.listMethods sercmd -f "pid: %v desc: %v\n" -s udp:localhost:2047 core.ps sercmd ps # uses default ctl socket sercmd # enters interactive mode on the default socket sercmd -s tcp:localhost # interactive mode, default port
