+Summary: SocketOptionName.ReuseAddress doesn't work on Linux
+
+SetSocketOption with SocketOptionName.ReuseAddress doesn't work on Linux
+(both Fedora and Ubuntu 6.10), but the same code works fine on Windows
+under mono.
+
+I am writing a piece of code to do TCP hole punching thru' the NAT, which
+requires that a process both listens on and connects from the same local port.
+
+Here is code to reproduce the issue. This code works fine on Windows under
+Mono, but not on Linux.
+
+
+Ubuntu/Fedora output:
+======================
+Listening on 4281..
+Got socket exception! System.Net.Sockets.SocketException: Address already
+in use
+  at System.Net.Sockets.Socket.Bind (System.Net.EndPoint local_end) [0x00000]
+  at MonoBug.Program.Main (System.String[] args) [0x00000] 
+
+Windows output:
+==============
+
+Listening on 2917..
+Connect done.
+
+
+How often does this happen? 
+All the time.
+
+Additional Information:
+I need this fixed urgently for my project, so a quick response/patch, or
+suggestions how/where to fix/patch is appreciated.
