AFAIK its point is to leave ports outside the range alone so that services can bind to well-known ports. > Does this define > non-reserved port ranges for *all* port spaces, or is it restricted to just > port spaces over IP? AFAIK AF_UNIX is also affected. I'll have to check. > Does SDP need to coordinate its use of port numbers with anything else? libsdp does this sometimes: - create 2 sockets - bind tcp socket to port 0 - get the port - bind sdp socket to the same port For this trick to work we must be able to bind same port for both TCP and SDP. -- Michael S.
