Is window scaling a Good Thing? I think the fix is needed on your OpenBSD firewall, according to this: http://kerneltrap.org/node/6723 David Miller: "Window scaling has been standardized and around for 14 years, RFC1323 was published in May of 1992. How much longer can we wait or it to be deployed properly? :-)" Window scaling is a good thing, because it improves speed on fast connections to distant sites; the problem is that if an intermediate node is buggy there are problems. The same thing happened for ECN. Best regards. -- Roberto Ragusa mail at robertoragusa.it
