<p>Hello,</p>
<p>can you reproduce the case and then get the output of the next
commands:</p>
<p>kamctl rpc core.tcp_list</p>
<p>kamctl rpc core.tcp_options</p>
<p>kamctl rpc core.tcp_info</p>
<p>Cheers,<br>

<p class="MsoNormal">Hi All,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In our setup running kamailio (alpine
image) in stateless mode and have following TCP config set.
After client registers to the backend see two TCP connections
created – one towards the client and the other towards the
backendserver. If there’s a abrupt network disconnect either
at the client side or at the backend side, do not see TCP
reset happening from kamailio as per the config. Per below
config expected after 120seconds( = [tcp_keepidle] + (
[tcp_keepintvl * tcp_keepcnt] ) instead it keeps resending TCP
keepalive packets at varying intervals for varying duration
length(like 6mins, 14mins..) before resetting the TCP
connections. Also want to mention that we are not using
TCPOPS module here.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am trying to achieve consistent duration
for TCP reset in kamailio. Could you please point me if I have
missed anything here?
