Recovering from a bad wsusscn2.cab download

[friday123]

UpdateGenerator downloaded a corrupt wsusscn2.cab. When I ran the generator again I saw this:

Code: Select all

Starting WSUS Offline Update download (v. 8.5) for w60 glb...

And in the log:

I tried deleting the client\wsus\wsusscn2.cab but that didn't work, I still got a file not found error. So I downloaded wsusscn2.cab manually and reset the hashes:

Code: Select all

cd client\wsus
del wsusscn2.cab
wget http://download.windowsupdate.com/microsoftupdate/v6/wsusscan/wsusscn2.cab
sigcheck -i wsusscn2.cab
cd ..\md
..\bin\hashdeep64.exe -c md5,sha1,sha256 -l -r ..\wsus > hashes-wsus.txt

Now the UpdateGenerator is running. I don't know whether or not you consider this a bug but I think it would be helpful if the program could auto-recover in the case of a bad wsusscn2.cab download. I don't know if anyone encounters the problem that they will figure out what to do. Thanks

The latest trunk version should already fix this (hashes are deleted after being verified good).

It doesn't. I just updated to 8.6 moments ago and my download is hanging on this cab - like forever. This cab hung up 8.5 as well.

Then please delete .\client\wsus\wsusscn2.cab and all text-files inside the directory .\client\md. Then restart the download.

...and define wsusscn2.cab as an exclusion to your on-access AV scanner, at least "on write".
It's a "zip bomb" and I guess your AV scanner makes it hanging; it's neither wget nor WOU.

Just an update - I stepped away from the computer to grab some breakfast - while WOU 8.6 continued thinking on this file...not sure when it finally let go - but it did and completed the iso creation.

Cheers,

Sonic.

As I said: It's not WOU thinking, it's your AV scanner, I suppose.

Well - what I saw for about 7 minutes while I was watching WOU "think" was that the file download was sitting at 99% and never actually "getting" to 100%...

I have since told ESET to ignore the entire WOU directory...see if that helps for next round.

Cheers!
