Two things: (1)
When there's nothing listening on those ports all the sockets, descriptors, queues, pcbs, etc... go away.
How about when a socket is actively listening? (2) Why when I do a traceroute to 0.0.0.4 or some similar bogus route, the router does not send an ICMP destination unreachable error back to me? My plan tonight was to hack the tcp_err() routine for sockets in the SYN_RECV state that is looking for an ACK and got an ICMP UNREACHABLE instead.... however, the ICMP UNREACHABLE CLUES never come. As my 5 year old nephew says.... " I NEED THAT !" Shouldn't these error messages be returned 'as a rule' ?? Thanks, Tim - - - - - - - - - - - - - - - - -
