Hello,
I have a requirement where the TLS connection initiated by kamailio shall stay to reuse by the sip server. The sip server is expecting PING on the TLS connection as as per the RFC 5626.
Is there any plan to implement ping "CRLF CRLF" send by kamailio as per the RFC 5626.
Thanks
Jijo

Hello,
tcp_keepalive is setting SO_KEEPALIVE which means sending keeplive by kamailio. You can watch network traffic with ngrep/tcpdump/wireshark...
The tcp parameters are documented on wiki:

Cheers,
Daniel

Hi
I want to use TCP keepalive to detect dead connections between Kamailio
and my SIP clients. I've got some questions about this:
1. If I enable it on Kamailio by setting for example:
tcp_crlf_ping = yes
tcp_keepalive = yes
tcp_keepidle = 60
tcp_keepintvl = 10
tcp_keepcnt = 3
From what I read by gooling, that means Kamailio only responds to the
crlfcrlf sent by the client, but can't be configured to send the
crlfcrlf. Is this right?
2. On my client, if I use setsockopt to set the corresponding values:
SO_KEEPALIVE
TCP_KEEPCNT
TCP_KEEPIDLE
TCP_KEEPINTVL
would it make the client send crlfcrlf?
The reason I'm confused is, with these settings, if Kamailio can only
respond to crlfcrlf, but not send, then would the client only respond
too, as in 1. and 2., they seem to configure the same set of parameters?
Please help me clarify this. Thanks very much!
