I have thousands of these in my logfiles. Any idea?


#2

Does your server have an IPv4 address?

Maybe check the kernel log (dmesg) and main syslog for clues related to network problems.


(Stephan Koenig) #3

Yes IPv4. The Router supports only that.


(Stephan Koenig) #4

I could use a little more help here. I still get tons of

IPv6 is disabled on the server. No IPv6 assiged.

IPv4 works find.


#5

Doubt anyone can help you without more context to the problem. When did it start, what kind of log messages show up along with these, what is happening when you see these, etc.


(Stephan Koenig) #6

I deteceted these warnings recently in the log files of my new FreePBX 15 system. However, I just saw that that have also been in my old 13 system.

I have IPv6 disabled on the 15 system and on the router.
I took out the IPv6 out of the hosts file.

The system runs fine.

There is one warning message per second.

I have no idea what else to check.


#7

A clue comes from the name associated with this IP:

173.251.65.159.in-addr.arpa	name = 5.sipis.acrobits.cz.

Acrobits “SIPIS” is the service used by Acrobits Softphone/Groundwire to do remote registration and push notifications. Are you using that?

Perhaps tcpdump on that IP address will yield even more clues.


(Stephan Koenig) #8

Thanks, I appreciate your help very much!
These are all all IPs from Acrobits push service.
We use their Groundwire client a lot, as it has a lot of configuration options…

I guess they send a request as IPv4 and expect Asterisk to answer with IPv6?

Please enable SIP debug to see what is triggering the error.


(Stephan Koenig) #10

I have tried to disable as much as possible as there is just too much traffic.

Does this show anything?

I found it, I changed the transport protocol from sips to sip, that handled it!

Thank you so much for showing me how to debug!
