On Windows we don't have Unix Domain Sockets. The emulation we use consists of a plain file giving a TCP port number. The server (e.g. gpg-gent) is listening on localhost and that port number. The client connects to localhost and that port number. This emulation yields semantics similar to a Unix Domain Socket. We use this IPC mechanism for interprocess communication between gpg and gpg-agent. gpg-agent and scdameon, etc. Given that the server is only listening for connections from localhost, this scheme is a pure local IPC mechanism. Unfortunately some firewalls don't get it right and try to protect against attacks from one-self. Salam-Shalom, Werner -- Die Gedanken sind frei.
