Re: [SR-Users] mhomed opened sockets

Hello,

I am not sure what ESTABLISHED is meant by netstat for UDP sockets, because there is no connection defined for UDP (datagram socket is kind of shoot and forget) -- maybe it track that there was some traffic and remembers that for a while. Perhaps reading the manual of netstat will help to understand better.

Cheers, Daniel

Hi Guys,

We have two network interfaces. One public and one private. We had
enabled mhomed and works great BUT if we do a netstat -naup | grep
5060 we see that some sockets keeps opened also when the call is
finished. The source port in netstat it's not 5060 so I suppose
that kamailio use another one for something else.

Is this the right behavior? How long does this sockets remain
opened? Are we missing something in our cfg?
