Upgrade of parent's CF failed, now have 1 day to fix

Owen Smith

Active Member
I tried doing a year's worth of CF updates to my parents HDR Fox T2 yesterday. It was very slow updating packages so I left it doing them all overnight (suspisciously little traffic on the router lights). This morning it had mostly finished and had somehow missed webchannel icons, I did that, rebooted, all seemed fine, did fix-flash-packages and it's all gone wrong. Now all I get is the web page offering me the button to install the full webif. I've clicked on that, and an hour later it's still claiming to be downloading. This can't be right.

I have precisely 1 day to fix this, and then it will have to stay however it ends up for 6 months until I'm at my parents again.

Help please, how do I get it all back and working again?

telnet access is working. I assume there's some diagnostic I can run which stands a chance of restoring things, but I have no idea which one.

I'm running diag fix-flash-packages from telnet since that seems to be what failed. It's got this far and then hung:

Why does fix-flash-packages try to install webif twice? And why did it work the first time and hang the second time?

I forced reinstallation of webif using this:

opkg install webif --force-reinstall

and then shutdown the HDR Fox T2 and power cycled it at the rear panel (shouldn't be necessary but sometimes seems to help).

and things are now working rather better. But I still can't get "fix-flash-packages" to complete without error, it now says this (and only makes one attempt to install webif I note):

Your last 'fix-flash-packages' run looks fine. I always get the message about it being unable to open 'favicon.ico': I think it must be a bug in the diagnostic itself. All 'favicon.ico' is is the little blue-rimmed oval icon that appears in the address bar of your browser when you open webif.

Thanks, in which case it's all working again and it was the force reinstall of webif that fixed it. Why it got into such a state is a mystery, it was working fine yesterday.

Looks like something went wrong with the webif upgrade but it's hard to work out what. The force re-install should have fixed it.

I sometimes have issues when trying to upgrade the webif package which may be related to this. Quite often I find that opkg upgrade will hang when trying to download webif. When this happens I usually resort to manually downloading it with wget. However, I can only download it in chunks. It will download about 20% of the file and then hang. Looking at my router lights show no activity at this time. I then have to do 'wget -c' to get the next chunk and so on until the full file is downloaded. I can then upgrade webif with opkg install <filename>

I wonder if there is some funky firewalling going on somewhere which may be causing this problem. I assume that the reason that this appears to be specific to webif is that it is one of the largest packages.

Yes, I've resorted to exactly that, and posted about this weirdness of the web server on a couple of separate occasions. One can only speculate based on the lack of action/feedback that it may be deliberate for whatever reason. Or it may not...

It might well be the largest but it's less than a couple of MB, which is hardly large in terms of shifting files around any sort of modern infrastructure.

True but most other commonly used packages are probably less than 20% of the size of the webif package. This may be the reason that webif seems most commonly affected.

I have been trying a few experiments. The final message before a hang is an outgoing TCP ACK packet to which it receives no response. It does eventually fail and then retry after the default wget read timeout of 15 minutes.

If I try changing the wget bw linit to 300KBps then it downloads fine but the problem reappears at 400KBps. Unfortunately the busybox version of wget dors not support the bw-limit option.

I'm not aware of any firewalling or bandwidth limits at the ISP end but I will see what I can find out. Package downloads are just flat files being served by Apache 2.4 so I wouldn't expect any problems!

Unfortunately I can't reproduce this from here. I'm running the Apache benchmark tool on a Mac laptop connected via wireless to my broadband router. My line speed is around 30Mb/s on a good day.

In my testing, disabling tcp window scaling on the Humax solves this. Not saying it's a problem at the Humax end but this looks like a good workaround.

sysctl -w net.ipv4.tcp_window_scaling=0

Thanks! Chances are I'll completely forget this by the next time it happens, but there's a chance a search of the forums will find this thread and answer.
