Hello Ovidiu,
Thanks for the fix. In regards to the pings from eyeBeam - how do you
want to reply to some dummy packages you do not understand ?
Best regards

The eyeBeam dummy packet is not that dummy.
It's a 4 byte packet: CRLFCRLF.
This is just like the TCP ping packet.
We could reply with CRLF, as Saul suggested.
See SIP outbound :http://tools.ietf.org/html/rfc5626#section-3.5.1

I see here:
This approach can only be used with connection-oriented transports
such as TCP or SCTP
So, maybe the package is not dummy, but it is wrongly used (over UDP) :)
Of course, technically can be done (to answer); the question is if it
make sense and if it is sane.
Regards,
That was my observation too (in one of my previous replies to Saul).
The thing is, if we reply to it, we can make the client's firewall
happy and we no longer need to perform server keep-alives.
I have mixed feelings about it :)

I also have mixed feelings on thisQuestion : is the practice of
using CRLF pinging via UDP a used one across UACs ?? or you just came
across a corner/isolated case ?

I came across this one by accident while dealing with STUN packets.
The thing is that those CRLFCRLF packets are discarded silently and
therefor is difficult to evaluate how often are they used.

I checked the code before my initial post and I wasn't sure if the 20
was the length of the whole UDP packet or just the payload.
It turns out that it is the payload and those packets from eyeBeam
were indeed discarded.
The trouble packets were in fact sent by a Grandstream device and
those were
Hi guys,
The UDP stack in OpenSIPS silently discards any packages less than 20
bytes. See the MIN_UDP_PACKET in config.h .
Are your pings longer than 20 ?!?

I forgot to mention in my previous e-mail that those ping packets are
over UDP, which seems like a bug in eyeBeam.
Anyway, the end result is that opensips logs are polluted.
Over TCP, it seems that those packets are properly handled by opensips.
It's UDP that is having issues.
