I have a problem viewing any webpage from the domain www.dent.ohio-state.edu, for instance http://dent.osu.edu/ddscurriculum/courselists.htm. This is only on my AMD Sempron64 box. The page will load part-way and 'hang', seeming to wait forever for the rest to load.

This problem seems identical to one I had two or three years ago, and at that time I fixed it by adding
Quote:
net.ipv4.tcp_default_win_scale = 0
in /etc/sysctl.conf.

Alternatively, a temporary solution was
Code:
echo 0 > /proc/sys/net/ipv4/tcp_default_win_scale


That solution came from this article: http://lwn.net/Articles/92727/.
But tcp_default_win_scale seems to be deprecated now, as kernel 2.6.18-gentoo-r4 doesn't recognize it.

Ideas?

Basically, now you can only enable/disable scaling using net.ipv4.tcp_window_scaling.
