There are broken (old) routers between you and the sites you're trying to contact. They don't support Explicit Congestion Notification (ECN; see RFC 3168). You should disable this in your new kernel. You can do so at runtime via something in /proc/sys/net/ somewhere (sorry, I don't know the filename off-hand. Take a look; it might be fairly obvious.) Or you can disable ECN at compile time by removing CONFIG_INET_ECN=y from your .config. See http://gtf.org/garzik/ecn/ for some useful info about ECN and why old routers behave the way they do. RFC 3168 is at http://www.faqs.org/rfcs/rfc3168.html noah -- _______________________________________________________ | Web: http://web.morgul.net/~frodo/ | PGP Public Key: http://web.morgul.net/~frodo/mail.html
