Seems like it would take just a few more lines of code in the loop that tries to find a working socket to check that we can send a byte and receive it. You'd have to be careful not to block if the socket is indeed not working ... also, is it safe to assume that a byte sent with send() is *immediately* ready to recv()? regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 4: Don't 'kill -9' the postmaster
