If you are using a 2.4 kernel disable ECN .. /proc/sys/net/ipv4/tcp_ecn or
something like that..

Hi Radel,

1. don`t use HTML E-Mails
2. try
echo 0 > /proc/sys/net/ipv4/tcp_ecn
or
sysctl -w net.ipv4.tcp_ecn=0

Greetings

Carsten

P.S.: You should be able to reproduce this problem with the following URL,

I cannot contact www.sella.it (a bank), but this site is perfectly reachable
using other way.
I've done some test:I've browsed to www.sella.it using samspade.org safe
browser, and I saw the page.
After that I'm switched to another provider, but the site was still
unreachable.
I'm connected a modem to a win98 pc and the site (using the same providers)
is visible.
So I think the problem is in the linux pc.
Because I'm using a proxy I've tried overriding it (using telnet
www.sella.it 80)but the result is the same:the connection timed out.
No problem with other sites... How to investigate?
