net.Listen("unix", ...) permission denied

[Roberto Zanotto]

Hi everyone.

I don't have experience with socket, I assume I'm missing something.

To start a unix domain socket server (on linux x64), I do the following:

sockDir := "/tmp/mydir"

if _, err = os.Stat(sockDir); os.IsNotExist(err) {

os.Mkdir(sockDir, os.ModeDir)

}

sockName := sockDir + "/" + "mysocket"

ln, err := net.Listen("unix", sockName)

I get: listen unix /tmp/mydir/mysocket: bind: permission denied

Should I create the file for the socket first? With which flags and permissions? Or maybe I shouldn't be doing this in tmp?

Thanks

Look at the permission of /tmp/mydir, it's likely 000.  Change os.ModeDir to 0755 (for example) above to allow your user access to the directory.

I totally missed the part of the least significant bits in os.FileMode. Thanks :)
