But it seems possible, to prevent such errors by carefully adjusting aria2c's download options. To prevent corrupted files, the downloader should not just resume the download after network failures, but always restart from scratch. aria2c may do that with the command line options:
- Code: Select all
--always-resume=false --max-resume-failure-tries=0 --max-tries=10 --retry-wait=10 --timeout=60
Also, the timestamping feature may work best, if the changed date of the local file is set to the timestamp of the remote file on the server. wget always does this, but aria2c needs another option:
- Code: Select all
--remote-time=true
If you used the script wsusoffline\cmd\ActivateAria2Downloads.cmd, you may find a file wsusoffline\cmd\custom\SetAria2EnvVars.cmd. Then add the above options to the line:
- Code: Select all
DLDR_COPT=--conditional-get=true --allow-overwrite=true --file-allocation=none -x10 -j10 -s10 -k1M -R
I also noticed, that aria2c does not create the download directory itself; the directory must always be created by the calling script. But the script wsusoffline\cmd\DownloadUpdates.cmd does not seem to do that. Each download section starts with:
- Code: Select all
if not exist ..\client\wddefs\nul goto DownloadWDDefs
and then it goes on with:
- Code: Select all
:DownloadWDDefs
echo Downloading/validating Windows Defender definition files...
%DLDR_PATH% %DLDR_COPT% %DLDR_IOPT% ..\static\StaticDownloadLink-wddefs-%TARGET_ARCH%-glb.txt %DLDR_POPT% ..\client\wddefs\%TARGET_ARCH%-glb
if errorlevel 1 goto DownloadError
This may not be enough for aria2c. The structure of the client directory, using German and English as languages for Windows 2003 Server and Office, should be:
- Code: Select all

Create these directories as needed.
wget, on the other hand, has some powerful recursive download options. It can be used to mirror complete websites, and then it creates the whole directory structure on its own.
