Windows Batch: wget to download Nirsoft tools - leads to corrupt files

Time:09-16

As I made a batch file to update NirSoft tools, I had a strange experience using wget.

First I downloaded a text file with pad links:

wget http://www.nirsoft.net/pad/pad-links.txt --backups=20 --append-output=C:\Path\Update\LOG\Nirsoft\%Timestamp%_NirSoft.log

After, I used fart-js to delete rows I did not need from the pad-links.txt file. Also I used that program to change the download links to https://www.nirsoft.net/utils, and change the file extensions to .zip.

fart ".\pad-links.txt" "http://www.nirsoft.net/pad" "http://www.nirsoft.net/utils" | tee --append C:\Path\Update\LOG\Nirsoft\%Timestamp%_NirSoft.log

and

fart ".\pad-links.txt" ".xml" ".zip" | tee --append C:\Path\Update\LOG\Nirsoft\%Timestamp%_NirSoft.log

After, to download the programs, I used:

wget --timestamping --input-file=C:\Path\UtilSuit\NirLauncher\Download\pad-links.txt --append-output=C:\Path\Update\LOG\Nirsoft\%Timestamp%_NirSoft.log

Having a look at the log file I found out that not all programs are stored in this location. For example WirelessKeyView is stored in https://www.nirsoft.net/toolsdownload/wirelesskeyview.zip.

Trying to get this file with wget leads to downloaded corrupt files at size of 4kb. The same with cURL and aria2. When I download it with Mozilla, or IDM, I have no problems to get the file. So I tried out wget --auth-no-challenge or wget --header="Accept: text/html" --user-agent="Mozilla/5.0 …"

I also tried cliget, the wget/aria2/curl lines it produced while normal downloading with Mozilla.

wget --header 'Host: www.nirsoft.net' --user-agent 'Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:92.0) Gecko/20100101 Firefox/92.0' --header 'Accept: text/html,application/xhtml xml,application/xml;q=0.9,image/webp,*/*;q=0.8' --header 'Accept-Language: de,en-US;q=0.7,en;q=0.3' --referer 'https://www.nirsoft.net/utils/wirelesskeyview.html' --header 'Upgrade-Insecure-Requests: 1' --header 'Sec-Fetch-Dest: document' --header 'Sec-Fetch-Mode: navigate' --header 'Sec-Fetch-Site: same-origin' --header 'Sec-Fetch-User: ?1' --header 'DNT: 1' --header 'Sec-GPC: 1' 'https://www.nirsoft.net/toolsdownload/wirelesskeyview.zip' --output-document 'wirelesskeyview.zip'

I googled and found this reference for powershell, (same error), but cannot reproduce the working answer in batch, (I am not familiar with powershell scripting).

So how is is possible to download the single wirelesskey.zip file with wget/curl or aria2 in a batch script?

A workaround I found out is downloading it directly from the pad Panel but I want the .zip-file, including the updated .chm-file, and also the 64-bit versions, if available.

One more note, within my anti-virus tool the nirsoft site is exempted from scanning, so that is not the answer.

Any solutions?

Aah, this one is simple. If you look at the actual page downloaded, it's called "403.html". So, let's open it. The first thing that strikes you is this:

<title>Error 403: Missing HTTP referer in the HTTP request</title>

So, the server wants a Referer header. Sure, let's give it one:

$ wget --referer foo <URL>

And it downloads the zip file correctly as expected.

Now, really, the server should not be returning a HTTP 200 response with a file called 403. It really should have sent back a HTTP 403 response. But what can you do? There's broken servers everywhere
