Re: [SR-Users] RTPENGINE question

Thanks Alex. So it turns out my rtpengine stopped working after our latest kernel upgrade to: Linux sjomainrtpe30 5.3.0-1035-aws #37-Ubuntu SMP Sun Sep 6 01:17:09 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux at the time, I was running an older version 8.0.x so I recompiled all the ngcp packages under this kernel and completed the installation without issues. As soon as we started making test calls, I received 0 audio from those test endpoints. Looking at the rtpengine logs, I see several messages that's quite concerning: Sep 11 18:43:41 sjomainrtpe30 kernel: [ 13.434623] xt_RTPENGINE: loading out-of-tree module taints kernel. Sep 11 18:43:41 sjomainrtpe30 kernel: [ 13.434670] xt_RTPENGINE: module verification failed: signature and/or required key missing - tainting kernel Sep 11 18:43:41 sjomainrtpe30 kernel: [ 13.434938] Registering xt_RTPENGINE module - version 9.0.1.0+0~mr9.0.1.0 and Sep 11 18:49:50 sjomainrtpe30 rtpengine[1030]: WARNING: [2-7859@2600:1f1c:4ff:3e01:f64d:2f67:c0fa:c931 port 50000]: No support for kernel packet forwarding available (decryption cipher or HMAC not supported by kernel module) which I assume is due to the first error I pasted. So I tried - rebooting the system which maybe the module wasn't loaded properly. - I reran modprobe to make sure the module is installed - I ran some dkms command to see if any error pop up due to the kernel version I'm running and I see no errors: dkms status falco, 0.20.0+d77080a, 5.3.0-1032-aws, x86_64: installed falco, 0.20.0+d77080a, 5.3.0-1035-aws, x86_64: installed ngcp-rtpengine, 9.0.1.0+0~mr9.0.1.0, 5.3.0-1032-aws, x86_64: installed ngcp-rtpengine, 9.0.1.0+0~mr9.0.1.0, 5.3.0-1035-aws, x86_64: installed So I'm running out of options. Any advice? On Fri, Sep 11, 2020 at 3:17 PM Alex Balashov <abalashov(a)evaristesys.com> wrote: -- Andy Chen Sr. Telephony Lead Engineer 415 516 5535 (M) achen@ <achen(a)thinkingphones.com>fuze.com
