Hello all, I am witnessing some very weird behavior: two processes listening on the same TCP port on the same machine. using Windows XP Professional
I thought this might be possible because my portable is multi-homed (wired + wireless network) ? But I disabled the wireless network and it still works. 1st process = org.apache.mina.example.chat.Main 2nd process = org.apache.mina.example.chat.SpringMain Running two instances of org.apache.mina.example.chat.Main gives the expected "Address already in use" but it seems I can start as many instances of SpringMain as I want (I tried upto 6) Ok, this behavior is clearly a consequence of setting reuseAddress=true on the SocketAcceptor but I have never witnessed this behavior on linux. Does anybody know whether this is a documented feature on Windows ? C:\netstat -na | grep 1234 TCP 0.0.0.0:1234 0.0.0.0:0 LISTENING TCP 0.0.0.0:1234 0.0.0.0:0 LISTENING TCP 127.0.0.1:1234 127.0.0.1:1379 ESTABLISHED TCP 127.0.0.1:1379 127.0.0.1:1234 ESTABLISHED (unfortunately netstat on windows doesn't have the -p option to show process id of listening process) Changing localAddress from ":1234" to "127.0.0.1:1234" or " 192.168.0.5:1234" doesn't make a difference. Clients seem to connect to the process that was started last. And when that server stops, new connections are accepted by an 'older' server. Maarten
