就是我试图要把几个socket都binding到同一个
地址(IP& port).
写的时候没注意... 就出了那种情况.
我想是应该有办法做到这一点的. seems apache did so.
有人有这方面的经验么?
恳请指点一二. |

发帖数: 35 | 2 in TCP programming you need to use mutiple bindings to the
same ports when
1. you have a server started->spawned children->server
terminated but children still running. and you want to
restart the server.
2. you are a multiple-homed host, that is u have more than
one IP addr in your host and you want to bind to more than
on IP addresses smultanously. like the case of a web
server.
You can do this with a SO_REUSEADDR socket option on.
if u r trying UDP or Multicasting, I do not know the
det

You dont normally need bind in an UDP case. (It is
specified in the sockaddr when you call recv() or
recvfrom()) Multicast is a special case for UDP.

SO_REUSEPORT is an unknown parameter.
is SO_REUSEADDR itself enough?
