myfavouritemagazines.co.uk down

Postby stayloose » Sat Feb 16, 2008 11:04 pm

I would like to subscribe to the magazine, but it seems that myfavouritemagazines has been offline for at least a couple of days. This poses two problems. The obvious one is that I can't subscribe right now, the second is that as a rule of thumb, I don't give card details to a company that can't even pay its hosting bills / configure a server.

I guess you guys hadn't realised that the site wasn't working? I wonder if this is common for the site, and if it indicates a bigger problem. Of course it could be something crazy to do with the terrible connection I have here whilst staying at my parents' house, but I doubt it.

Ha ha, you couldn't make it up!

It doesn't work in Opera either in Linux. I guess I'll have to wait a couple of days to get back to a box with XP in VirtualBox. I think this is the first site I have ever been totally unable to use in Linux.

It does still have me a little worried about their competence over there,

//Edit

It's not compatibility issues:

Hey!

The site works fine; the problem seems to lie with Linux. We've done numerous tests over here, and some Linux boxes just don't seem to handle the MFM connection properly - even when XP/Vista/OS X machines work fine from exactly the same network. Even stranger is that some Linuxes work fine, and others don't!

We reckon someone, somewhere between us and MFM has changed some hardware that does something funky with TCP window scaling, and Linux (particularly newer kernels) just flat out rejects it. The MFM site isn't actually run by Linux Format or Future Publishing, which is why it's taking so long to get it fixed!

We're on the case trying to narrow down the problem and get it sorted. In the meantime, see if this solves the problem:

1) Open a terminal window
2) Switch to root
3) Execute: echo "0" > /proc/sys/net/ipv4/tcp_window_scaling

Take care,


Paul

That does solve the problem! Thanks for your help. I can't say I know the first thing about TCP window scaling, but I shall now have a good look at some relevant literature.

Subscribing as I type :)

That solves the problem on my Eee PC (Xandros Advanced Desktop Mode). I'll try later on my Ubuntu system.

Is it the way IIS is responding to the page request through .NET? Microsoft deliberately breaking the Internet again!

Ollie: IIS does have some strange things in it, but this doesn't appear to be a Microsoft problem. Strangely enough, Vista is the first Microsoft OS to support TCP window scaling (AFAIK), and yet MFM works fine on there!

:D I'm sure its all a dirty MS conspiracy. Well, no, its been around for a while. I have had problems at one site (due to an OpenBSD based firewall/router box) for months. The only way I could ever get to the internet from Linux at that site was to have this in /etc/sysctl.conf:

Code: Select all
net.ipv4.tcp_window_scaling=0


Took ages to track down. Especially since the I have XP, OS/2 and FreeBSD on the same laptop, and it was only Linux that was having access problems...

Since that site has changed to an SME Server based firewall/router box, the problem has vanished - I experimented by moving sysctl.conf to another name and found no problems accessing the net....

Worked for me

Postby darkmane » Tue Feb 19, 2008 12:58 pm

Just need to wait patiently by the letter box for a couple of months, for the postie to come a visiting :lol:

Hey!

If they gave you a subscriber number already, it might work for the online subs area right now. No harm trying!

Did you try the TCP scaling thing? That fixed it for me.

I've just done some research on this. See http://en.wikipedia.org/wiki/TCP_window_scale_option (and the links at the bottom of the article.

Now, on http://support.microsoft.com/kb/934430 there is this:

"By default, the Receive Window Auto-Tuning feature in Windows Vista uses a Window Scaling factor of 8 for non-HTTP connections. This issue does not occur when you try to make an HTTP connection."

I would imagine that Linux uses it for all traffic and that's the problem. Somewhere along the line is a screwed up router/firewall which mucks up the TCP Receive Window negotiation. Vista et al work OK because they don't use it. Linux fails.

So it would appear that My Mags have picked an ISP that can't manage an internet connection properly. They are excluding quite a lot of readers and are making inefficient use of their bandwidth. Personally speaking, if I were them I'd be asking questions and not putting up with "it works on Vista" style answers. Using just a Windows machine as a diag tool is masking the fault. They (MFM) are still being fleeced and Linux users are wasting time and ham stringing their boxes.
