I beleive ECN (Explicite Congestion Notification) is set on in the kernel.
To confirm , 'cat /proc/sys/net/ipv4/tcp_ecn'
If 1 then it's on. Some routers and or firewalls drop packets with the
ECN bits set.
To turn off, 'echo '0' >/proc/sys/net/ipv4/tcp_ecn'
It is strange, but this computer (at home) has exactly the same problem.
If I use one of Arjan's test kernel then I can't make TCP connections at
all. I CAN ping hosts (local network or Internet) but I can't connect
anywhere. (And no, tcp_ecn is off).
Do you want to hear the strangest thing? If I get Arjan's kernel-source
RPM and recompile USING THE .config file for i686 from there, then
everything works fine.
Currently I am using:
[root@home root]# uname -a
2.6.0-0.test5.1.34custom #2 Sun Sep 14 16:08:26
CDT 2003 i686 i686 i386 GNU/Linux
(notice the "test5" but also the "custom" part) and I don't have
problem with this kernel.
At office, I can use Arjan's kernels without any problem, so, I haven't
worried to fill a bug since I can't imagine where to start doing it (or
if I should).
Anyway, just my two cents.
