Re: [SR-Users] Kamailio stop responding to AWS R53 health check

14 Nov 2019

Hello,

first to clarify it: the fix for libssl referred as being in 5.3.0 is
also in 5.2.5, with a slightly different approach (some code is directly
in tls module in 5.2.5, while in 5.3 has been added to the core), but
same overall result. So that should not be an issue anymore in branch
5.2 starting with 5.2.5.

Now back to the log messages, they didn't suggest that Kamailio is
frozen, but that Kamailio didn't accept the tls connections because of
mismatching the method or no common ciphers.

Did kamailio route the usual SIP traffic when this check was done by AWS
R53?

What is the TLS method you set in tls.cfg?

Cheers,
Daniel

  Btw..I saw the git repo on the bug.  I also
experienced libcrypto
 coring and was told 5.2.5 would fix it.  However, in my case libcrypto
 didn't core.  Kamailio basically just stopped sending any responses
 back to tcp ping requests from R53 (or even telnet 5060 didn't respond).

     Hi Karsten,

     These are our current settings:

     root@sjoprodkama51:/var/log # grep max_connections
     /etc/kamailio/kamailio.cfg
     tcp_max_connections=32768
     tls_max_connections=32768
     root@sjoprodkama51:/var/log #

     which seems more than enough I would think.

         Thanks Jurijs.

         We just upgraded to 5.2.5 to support openssl 1.1.1 which is
         required for ubuntu 18.04.  Is it possible to have back port
         this fix to 5.2.x release since we just released 5.2.5 through
         our battery of QA testing?

             Hi Andrew,

             I'm pretty sure this is bug what you are talking about:

             https://github.com/kamailio/kamailio/issues/1860

             It should be fixed in 5.3.0 I believe, or you can always
             downgrade openssl to 1.0 as described here:

             https://www.kamailio.org/wiki/tutorials/tls/howto-openssl-1-0

                 So another update.  As it turns out, this remote IP
                 sent a slew of tls connections to the Kamailio box
                 within the same second:

                 root@sjoprodkama51:/var/log # grep 104.248.215.53
                 falco_events.log | wc -l
                 114
                 root@sjoprodkama51:/var/log # 

                 this all came in at 18:28:05 which matches the time of
                 those errors.

                 Should this cause Kamailio to totally freeze up?

                     Hi Karsten,

                     Good point.  See below:

                     Kamailio ver: 5.2.5+bionic
                     Ubuntu version: 18.04.02 LTS
                     Kernel version: 4.15.0-1043-aws #45-Ubuntu SMP Mon
                     Jun 24 14:07:03 UTC 2019 x86_64 x86_64 x86_64
                     GNU/Linux
                     openssl version: 1.1.1-1ubuntu2.1~18.04.4

                     Setup:
                     - R53 is our load balancer on top running health
                     check on a pair of kams.
                     - First node has no issues and running the same
                     setup + SIP traffic
                     - Second node as shown above was the one that went
                     into "Unhealthy" state.

                     Hope this helps

                         Would help if you could could describe your
                         setup a bit more. 

                         Like the Kamailio version, the system distro
                         and as we see many tls messages your openssl
                         version. 

                         Maybe the traveling developers have any ideas
                         then.

                             Hi all,

                             R53 reported healthcheck failure on tcp
                             port 5060.  Looking at the system, all the
                             ports that kamailio listens on can't be
                             monitored remotely.  To test this theory,
                             I can telnet successfully to consul port. 
                             I ran tcpdump and see no responses
                             returned back to R53 monitoring hosts:

                             Fixed the issue after restarting kamailio
                             process.

                             Given this system is support production
                             traffic, we have minimized the logging on
                             it.  The events that we thought may lead
                             to this is as follows:
