Thanks for the quick reply. I looked at the sr_module.h and saw the defs that you are talking about. Now I am starting SER with fork=yes and children=2. so I get the following output from serctl ps cmd. [root@test gl]# serctl ps 0 10771 attendant 1 10773 receiver child=0 sock=0 @ 192.168.160.12:5060 2 10774 receiver child=1 sock=0 @ 192.168.160.12:5060 3 10775 fifo server 4 10776 timer 5 10777 tcp receiver 6 10778 tcp receiver 7 10779 tcp main process The only rank values that I can count on not to startup a socket connection in the child_init function are -1, -2, -4. The question I have is, how can I know in my child_init function that the process that the child_init() function is called from is "receiver child=n" ? for example I know that if I have set children=2 in ser.cfg than the first 2 times the child_init function will be called from the receiver child=0 and receiver child=1 thread. Also How come the tcp receiver is getting started for each child ? I hope that I am making sense here. thanks, Jignesh Gandhi -----Original Message From: Jan Janak To: Gandhi, Jignesh Cc: 'serusers(a)lists.iptel.org' Sent: 11/3/2004 11:08 AM Subject: Re: [Serusers] RE: SER in debug mode no fork mode means that there will be only one process listening for and processing SIP messages. In addition to that there will be also the timer process (taking care of timers) and fifo process (processing commands sent to ser over the FIFO interface). The child init function will be called for all of them. See: root@localhost:/home/janakj# serctl ps 0 6266 stand-alone receiver @ 127.0.0.1:5060 1 6267 timer 2 6268 fifo server If you want to execute the code in the listening process only, then you can ignore calls of child_init that have the parameter set to PROC_TIMER and PROC_FIFO (defined in sr_module.h). Note that it is usually a good idea to have the same environment in the timer process as in the receiver as some functionality might be called from the timer. Jan.
