Hello,

Yes it is sending CRLF after the second CRLF from client. 

Another thing is, Kamailio would send CRLF even if the second CRLF come after few seconds.

I believe we don't have any way to drop it ?

Thanks

There is no notion of a packet in a stream connection, even a sip packet can be send char by char and the server has to assemble it by keep reading in a local buffer until all is retrieved.

Hi

Sorry for the late reply,

I observed this issue when testing with broken TLS UA, which was sending CRLF in two packets instead of double CRLF in a single packet.

It is very easy to recreate using openssl s_client command , where kamailio as server

 openssl s_client -connect 192.168.2.151:5061  -CAfile serverCA.pem  -crlf


After the connection established by the client, Press enter key two times from the key board, which will send CRLF in two packet to server and You would see CRLF replied back by Kamailio 

Note:-crlf will send CR as CRLF in a single packet to server.

Thanks

Hello,

looking at the code, it seems that CRLF is sent only after CRLFCRLF. Can you get a pcap for your case?

Cheers,

Hi All.

As per the tcp_crlf_ping description, kamailio shall reply CRLF only when it receives "CRLF CRLF".  But In the 3.1.0 version, if kamailio recieves "CRLF", it respond back CRLF.  Is this an expected behavior or an error?

Thanks
Jijo
