Hi Cesc, Could you send the your script that checks the ser activity. What I do is to check the ser processes via ps -ax but as I see your solution is better.

What i did to monitor ser and sems was to create bash scripts which restart ser and/or sems in case of failure. For ser, the script sends fake REGISTER messages (with expires=0). If the answer is 200 OK (or a 40x proxy authenticate) ... then ser is alive. If nothing is read, then i restart ser. For sems, i tried two approaches. - active: send a specially crafted message (INVITE) so that you know for sure that ser will route it to SEMS ... depending on the answer, you should be able to know wether SEMS is alive or not ... but this has a problem (see below for a larger explanation). - passively: start sems so it writes its PID to a log file ... then monitor (using ps aux) that pid ...if not there, restart SEMS. - i seem to remember someone mentioned a status module for sems, which would allow you to send commands via the fifo/unixsock interface, and check actively sems (including activity statistics) ... is this true? ===== ACTIVE MONITORING PROBLEM What i tried to do is to created unique INVITE messages, which i make sure that ser routes to sems. They had unique call-ids and to/from tags ... thus theoretically ser should see them as independendent requests. But, if sent these INV requests too often (that is, less than a minute or so ... time enough for the transaction to be destroyed in ser mem, i guess ... ), ser would mistakenly think they were retransmissions ... It would also start acting weird and sending replies to the wrong port ... This is why i went to passive monitoring ... i do not have time to investigate any further ... but i can provide the script for someone else to try ... BTW, i use ser 0.9.6 Regards, Cesc On 1/27/06, hgaillac-sip(a)yahoo.fr <hgaillac-sip(a)yahoo.fr> wrote: _______________________________________________ Serusers mailing list serusers(a)lists.iptel.org http://lists.iptel.org/mailman/listinfo/serusers
