A friend has a strange problem that I have been unable to solve, so
I thought I'd canvas for suggestions here.
Since the last week or so, he has been unable to log in to Facebook
or Hotmail from Ubuntu. He has a dual-boot machine with Ubuntu 8.04
and Windows XP. He is connected via a MTNL Triband connection. Both
sites still work fine in XP. Other sites work fine in Ubuntu. He's
tried several alternate browsers besides Firefox, including Opera,
SeaMonkey, etc. but has the same problem there. Sometimes the login
page on Hotmail loads up, but logging in doesn't produce any
response. In Facebook again, sometimes the login page loads, but
doesn't work. In SeaMonkey, sometimes logging in to Facebook does
proceed to the home page, but then no other links work.
See if turning ECN off helps:
cat /proc/sys/net/ipv4/tcp_ecn (note whether it's 1 or 0).
echo 0 > /proc/sys/net/ipv4/tcp_ecn
If it's off, you could try turning it on :)
