David,

I think the "accept sockets" are the ones you pass to listen(), the
"local sockets" are the ones you get from accept() and the "remote
sockets" are the ones you pass to connect().

That is, the "accept sockets" are to wait for connections.  The "local
sockets" carry encrypted data in server mode and plain data in client
mode, and the "remote sockets" carry plain data in server mode and
encrypted data in client mode.

HTH,

Ludolf
