CentOS - Jul 2009 - Network guru please help: baffled by missing file

The mirrorlist entry in my Fedora-11 /etc/yum.repos.d/fedora-update.repo
reads:
mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=updates-released-
f$releasever&arch=$basearch

As far as I can see, this means that yum is looking for
the file metalink at mirrors.fedoraproject.org ?

If I try "sudo yum update" I get:
-----------------------------------

When I look at the http traffic on my server with wireshark
the file-request seems to be properly sent,
but the file is not found.

The symptoms seem to me (no http expert) to suggest
that there is some condition for seeing this file
that my system is not fulfilling.

Any and all suggestions gratefully received.

This is a list for CentOS, not Fedora.  You'll get better help if you
post to the right lists :-)

Sorry, I should have said that my server is running Centos-5.3.
If there is a problem on my system, it is at the server.
I ran wget on the server, and got the same result.
I also get the same result for EPEL:

---------------------------------
using the mirrorlist line in /etc/yum.repos.d/epel.repo :
mirrorlist=http://mirrors.fedoraproject.org/mirrorlist?repo=epel-5&arch=$basearchkk

Also wget fails similarly:

I don't think so.
My server is connected to an ADSL modem which links it to my ISP.
I don't know if the modem (Cayman 3341) could be acting as a proxy server?

I'm running shorewall on the server,
but I get the same response when I turn it off.

As I said, it seems to me that mirrors.fedoraproject.org
for some reason does not like my system.
I can connect to this site, and download files from it,
eg index.html, static/css/fedora.css, etc.
It is just the files mirrorlist and metalink
which I cannot see.

I never get this problem in any other context, as far as I know.

Does it work if you use http:// instead of https:// with the same URL?

Hi,

It's a problem with the mirror you are using (209.132.176.122), it
seems to be bogus or out of sync:

I am getting mirror 209.132.176.120 (and some others), which seems to
be working OK:

I see you also tried to access the IP directly (wget
http://66.35.62.166/mirrorlist) but that does not work probably
because the server uses virtual hosts and the default virtual host is
probably not the one you want. It's possible to work around that by
using --header 'Host: mirrors.fedoraproject.org' in the wget command
line.

For example, the same host I used above:
> $ wget --header 'Host: mirrors.fedoraproject.org'
http://209.132.176.120/metalink
> --12:56:07--  http://209.132.176.120/metalink

And the one you are using:

http://209.132.176.122/metalink
> --12:56:12--  http://209.132.176.122/metalink

To work around this issue, I suggest you add a line with
"209.132.176.122 mirrors.fedoraproject.org" to your /etc/hosts, and
also contact the Fedora project to inform them that this specific
mirror is bad... You might also try to flush your DNS cache to see if
you get a new IP for that domain.

HTH,
Filipe

Why would you want to link to Fedora's Repo's?
So you can have an unstalbe Centos box?
