Where does this limitation come from? One might be tempted to relate the maximum number of TCP connections to the 16-bit size of a TCP port number, but that doesn't work because TCP connections are typically identified by a four-tuple which includes the source and destination IP addresses as well as the source and destination port numbers. In theory, a TCP stack with only a single bound IP address can maintain ~64K independent connections to _every_ peer even when using only a single local port, so I'm guessing the 2^16 - n number must be coming from some other implementation-dependent limitation. Or am I just up in the night? :-) Chris /* PLUG: http://plug.org, #utah on irc.freenode.net Unsubscribe: http://plug.org/mailman/options/plug Don't fear the penguin. */
