Linux socket doesn't close

Question

i have a problem. I run a TCP server in linux. I close the socket by close(socket) call. But when I try to rebind again, bind call fails with errno 98 => port is already binded. How should i unbind that socket?

Might this help?: http://stackoverflow.com/questions/2208581/socket-listen-doesnt-unbind-in-c-under-linux — Bart, May 06 '11 at 09:09

You have to set SO_REUSEADDR option on the socket, see here.

Thank you, it really helped. Strange that it is not needed in Windows if I run the application there. – Erkil1452 May 06 '11 at 10:10

You can try setting the SO_REUSEADDR socket option, see this question for some discussion.
