Hello,
you must have a different socket in modparam("evapi", "bind_addr", "...") than the core listen parameter for sip tcp traffic. The connect with your evapi app to the socket specified in modparam.
Cheers, Daniel

hello Daniel
i have tried the directive listen=127.0.0.1:8448 http://127.0.0.1:8448 and listen=tcp:127.0.0.1:8448 http://127.0.0.1:8448 and i tried now for example to connect with a tcp client from port 48583 (randomly selected when i made the tcp connect i guess)
tcp 0 0 127.0.0.1:8448 http://127.0.0.1:8448 127.0.0.1:48583 http://127.0.0.1:48583 ESTABLISHED 4508/kamailio keepalive (2.24/0/0)
i configured the kernel to send keep alives 30secs after the tcp connection
should this be ok?
best regards david

Hello, to what port do you connect for evapi? The logs indicate connection to sip tcp port.

I have the kamailio (version 5.3) running with a tcp socket 127.0.0.1:8228 <http://127.0.0.1:8228>, and the evapi params are just modparam("evapi", "workers", 4) modparam("evapi", "netstring_format", 0) modparam("evapi", "bind_addr", "127.0.0.1:8448 <http://127.0.0.1:8448>") modparam("evapi", "max_clients", 32) I tried a different number of workers and netstring_format 1 too. When I start the kamailio i added some debug to the code, and seems when doing the mod init of the evapi dispatcher 38(4779) DEBUG: <core> [core/sr_module.c:779]: init_mod_child(): idx 38 rank -2: evapi [EvAPI Dispatcher] it reaches to while(1) { ev_loop (loop, 0); } at evapi_run_dispatcher function. I guess if I connected to the tcp socket and sent some event, I would see the client accepted and the event route evapi:connection-new would be triggered. But i'm not able to do that. I tried to use the prime option, a tcp input client connection from logstash, so i could relay the data to the logstash using the evapi relay, but i only see the tcp socket being created but no client accepted. I also tried to connect with an erlang gen_tcp client, but it's the same i only see 47(4798) DEBUG: <core> [core/ip_addr.c:229]: print_ip(): tcpconn_new: new tcp connection: 127.0.0.1 47(4798) DEBUG: <core> [core/tcp_main.c:1174]: tcpconn_new(): on port 54537, type 2, socket 105 47(4798) DEBUG: <core> [core/tcp_main.c:1497]: tcpconn_add(): hashes: 1117:1187:1505, 1 47(4798) DEBUG: <core> [core/io_wait.h:375]: io_watch_add(): DBG: io_watch_add(0xad0880, 105, 2, 0x7fc211712d58), fd_no=53 and if i try to send any data 47(4798) DEBUG: <core> [core/io_wait.h:600]: io_watch_del(): DBG: io_watch_del (0xad0880, 105, -1, 0x0) fd_no=54 called 47(4798) DEBUG: <core> [core/tcp_main.c:4456]: handle_tcpconn_ev(): sending to child, events 1 47(4798) DEBUG: <core> [core/tcp_main.c:4129]: send2child(): selected tcp worker idx:0 proc:43 pid:4791 for activity on [tcp:127.0.0.1:8448 <http://127.0.0.1:8448>], 0x7fc211712d58 43(4791) DEBUG: <core> [core/tcp_read.c:1749]: handle_io(): received n=8 con=0x7fc211712d58, fd=39 43(4791) DEBUG: <core> [core/io_wait.h:375]: io_watch_add(): DBG: io_watch_add(0xb3c720, 39, 2, 0x7fc211712d58), fd_no=1 43(4791) DEBUG: <core> [core/io_wait.h:600]: io_watch_del(): DBG: io_watch_del (0xb3c720, 39, -1, 0x10) fd_no=2 called 43(4791) DEBUG: <core> [core/tcp_read.c:1671]: release_tcpconn(): releasing con 0x7fc211712d58, state 1, fd=39, id=1 ([127.0.0.1]:54537 -> [127.0.0.1]:8448) 43(4791) DEBUG: <core> [core/tcp_read.c:1672]: release_tcpconn(): extra_data (nil) 47(4798) DEBUG: <core> [core/tcp_main.c:3559]: handle_tcp_child(): reader response= 7fc211712d58, 1 from 0 47(4798) DEBUG: <core> [core/io_wait.h:375]: io_watch_add(): DBG: io_watch_add(0xad0880, 105, 2, 0x7fc211712d58), fd_no=53 47(4798) DEBUG: <core> [core/tcp_main.c:3686]: handle_tcp_child(): CONN_RELEASE 0x7fc211712d58 refcnt= 1 and when i try to send any data 38(10867) DEBUG: evapi [evapi_dispatch.c:610]: evapi_recv_notify(): received [0x7f17d23fc628] [{"test" : "1.1.1.1", "uuid" : "1-31629@3.3.3.3 <mailto:1-31629@3.3.3.3>" , "pdd" : "4"}] (75) 38(10867) DEBUG: evapi [evapi_dispatch.c:316]: evapi_dispatch_notify(): the message was sent to 0 clients I don't know what i'm missing, or if i'm understanding the use of the module correctly could you please take a look? thanks a lot David -- Logo David Escartín Almudévar VoIP/Switch Engineer descartin@sonoc.io <mailto:descartin@sonoc.io> *SONOC* C/ Josefa Amar y Borbón, 10, 4ª · 50001 Zaragoza, España Tlf: +34 917019888 · www.sonoc.io <http://www.sonoc.io> _______________________________________________ Kamailio (SER) - Users Mailing List sr-users@lists.kamailio.org <mailto:sr-users@lists.kamailio.org> https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users <https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users>-- Daniel-Constantin Mierla -- www.asipto.com <http://www.asipto.com> www.twitter.com/miconda <http://www.twitter.com/miconda> -- www.linkedin.com/in/miconda <http://www.linkedin.com/in/miconda> Funding: https://www.paypal.me/dcmierla <https://www.paypal.me/dcmierla>-- Logo
