That's a good explanation, I believe they use socket.h for socket(), bind(), connect(), recv(), send() etc. In this case it's definitely, that AF just sticks with numbers defined by the IANA.
" I think that proto 3 in OpenSIPS is TLS, but I don’t have a reference for that one." - I have doubts regarding this, since I don't have any TLS in my network. To be honestly it's almost impossible that TLS would appear within it. But that's a good thought, I hope some of OpenSIPS project developers will clear our this for me. пн, 8 апр. 2019 г. в 16:46, Ben Newlin <[email protected]>: > I believe Address Family (AF) 2 is IPv6 [1]. > > > > The protocol number is not the index of the listener, it refers to the > actual protocol being used.
