kernelized packets visibile in user-space #1762

Closed rohjac closed 7 months ago

rohjac commented 7 months ago

i have installed kamailio with rtpengine on ubuntu 22.04 system with 8gb ram and the versions are as follows: kamailio : 5.5.7 rtpengine : 11.5.1.9+0~mr11.5.1.9+omnivigil1

on establishing call the rtpengine logs are as shown:

Nov 24 11:21:51 telecom-HP-ProBook-430-G5 rtpengine[4011]: INFO: [803DCD1E-FB88-EE11-873F-C7E80122A74D@192.168.12.25/1973482320/1 port 34962]: [core] Kernelizing media stream: 192.168.12.25:5062 -> 192.168.12.20:34962 | 192.168.12.20:37136 -> 192.168.12.159:5012 Nov 24 11:21:52 telecom-HP-ProBook-430-G5 rtpengine[4011]: INFO: [803DCD1E-FB88-EE11-873F-C7E80122A74D@192.168.12.25/1370322772/1 port 37137]: [core] Confirmed peer address as 192.168.12.159:5013 Nov 24 11:21:52 telecom-HP-ProBook-430-G5 rtpengine[4011]: INFO: [803DCD1E-FB88-EE11-873F-C7E80122A74D@192.168.12.25/1370322772/1 port 37137]: [core] Kernelizing media stream: 192.168.12.159:5013 -> 192.168.12.20:37137 | 192.168.12.20:34963 -> 192.168.12.25:5063

It shows that rtpengine is enabled with kernel-mode, it is working but i am observing the packets on wireshark which is opened on the same system where kamailio and rtpengine is running, i am assuming that packets should not be seen in wireshark.

please correct me if am wrong

The iptable content is as follows:

-P INPUT ACCEPT -P FORWARD ACCEPT -P OUTPUT ACCEPT -N rtpengine -A INPUT -p udp -j rtpengine -A rtpengine -p udp -j RTPENGINE --id 0

More over the kamailio server with rtpengine is not able to handle more than 500 simultaneous calls

Your assumption is incorrect. The packets will be visible in Wireshark even if handled by the kernel module.
