Well, turns out that a Linux 2.0 box also stalled on this. However, methinks it might be time to raise the issue of default settings for RFC 1323 extensions in FreeBSD boxes. Since RFC 1323 deals with long fat pipes, which very few of us have, it would make sense to turn the extensions off in the shipped /etc/sysconfig. Those people who are communicating with TCP between the two ends of a 1.5 Mbps satellite link, or an intercontinental 45 Mbps link, probably know who they are and can turn the extensions on. I know that some people in the continental USA can claim a 45 Mbps path to their favourite ftp site 4 states away, but surely those paths are used by others, reducing the 'fatness' of the pipe for RFC 1323 purposes. Local area ATM might be 'fat' but generally is not 'long' enough to cause the problems with RFC 1323 addresses. Leaving the extensions on by default causes much grief for people with old Annexes, prevents people whose ISPs use Annexes from reading FreeBSD box web pages or sending mail to FreeBSD boxes, and generates enormous amounts of traffic on the FreeBSD mailing lists. regards, Danny
