Strange problem accessing Virgin.net servers

Strange problem accessing Virgin.net servers

Post by Chris Gordon-Smit » Sun, 17 Apr 2005 05:43:03



Can anyone suggest what might be causing this very strange problem.

I have a SuSE 9.2 desktop PC that I connect to the Internet using an ADSL
modem / router.  Currently my Internet access is all working fine, except
that I am not able to access the website www.*.net, and I am also
unable to access my * pop account on their server pop.*.net.

I am also unable to ping either of these addresses, although ping is able to
resolve the corresponding TCP/IP addresses.

My broadband connection is from another ISP (not *). I have spoken to
*'s technical people. They say that all their servers are currently
working fine, and my brother in law also says that his * email account
is working fine.

How is this possible? I can ping Google or the BBC website and access any
other site I can think of, except *.

Can anyone explain?

Firewall?

What does traceroute -n www.*.net say?  My traceroute dies at
213.105.172.153 (inet.ntl.com).  Pings are not replied

How about traceroute -n pop.*.net ?  My traceroute dies at
64.97.128.98 (dia.cp.net).

What message(s) do you see when you http://www.*.net  or try to
retrieve your mail?

I am able to telnet www.*.net 80 and to
telnet pop.*.net 110

What little help I can offer is that the problem appears to be that
your firewall is saying NO.

    Just as a guess, do you have ECN enabled? (Explicit Congestion
Notification)

I don't think I have ECN enabled, and have in any case manually disabled it
with
echo "0" > /proc/sys/net/ipv4/tcp_ecn

as mentioned on SuSE's website                      

Here is what I get from tcpdump -p  -i any port 80

when I try to access www.*.net with the lynx text web browser and
specify 'unset http_proxy' :-

My reading of this is that absolutely nothing is coming back. Any thoughts?

There's something fishy going on at the NTL routers. My traceroute
disappears into a black hole after gfd-dc-d-v300.inet.ntl.com
(213.105.172.157).
