Wayback machine and VMware KB links

Posted by jpluimers on 2022/03/22

The VMware KB is notoriously bad into being saved in the WayBack Machine: saved links hardly render at all because of the VMware KB dynamic page loading structure.

But VMware KB articles expire, so a lot of web-pages point to non-existing links and end up through redirections at [Archive.is] https://kb.vmware.com/s/pagenotfound.

Below are a few link forms of the same VMware KB 2011818 article that vanished from the regular web. The first is saved in the WayBack Machine (but does not render), the second is saved and does render after a redirect to a saved third form, the most recent saved fourth form is actually a 404-error redirecting to a prior third form.

  1. https://kb.vmware.com/s/article/2011818
  2. http://kb.vmware.com/kb/2011818
  3. http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2011818
  4. http://kb.vmware.com:80/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2011818

The first link form does archive as a rendered page in Archive.is if is is archived. t wasn’t, so the current archived version points to the “pagenotfound” page mentioned above.

Sometimes you have to dig deeper, as not all rendering archived versions contain actual content.

Here the first one is not even archived, the other ones are, but none of them have actual usable content:

  1. https://kb.vmware.com/s/article/2007922
  2. http://kb.vmware.com/kb/2007922
  3. http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2007922
  4. http://kb.vmware.com:80/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2007922

This means you have to dig further in history:

  1. https://web.archive.org/web/20140123114343/http://kb.vmware.com:80/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2007922 indicates not authorized
  2. https://web.archive.org/web/20130117041323/http://kb.vmware.com:80/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2007922 shows the actual content.

Digital accessibility is hard; Wayback archival of: Formulieren – CIZ

Posted by jpluimers on 2022/03/17

I know that digital accessibility does not come for free, but it is mandatory in Europe for at least documents and web-sites provided by government and semi-government as per [Wayback] EN 301 549 – Wikipedia

EN 301 549 is a European standard for digital accessibility. It specifies requirements for information and communications technology to be accessible for people with disabilities.

I bumped into numerous tab-order issues when filling out CIZ forms. This makes it way harder for my, as now I require a mouse despite having RSI symptoms for some 30+ years.

So, for my link archive so I can document that all these forms have severe tab-order issues (some fields are not even accessible by keyboard, are being emptied when you leave the field, or not even accessible by mouse): [Wayback] Formulieren – CIZ

Doet u een aanvraag bij het CIZ? Op deze pagina vindt u een overzicht van onze formulieren, zoals een machtigingsformulier en het Wlz-aanvraagformulier.

Hopefully by now the forms have been fixed.

Cryptosense Discovery

Posted by jpluimers on 2022/03/15

This is cool: [Wayback] Cryptosense Discovery:

Free tool that discovers security configuration errors in SSH and TLS servers and explains how to fix them. Supports STARTTLS and can also scan HTTPS, POP3, IMAP and SMTP servers.

It gives you a list of servers a target domain uses (for purposes like web, email, etc) that can have external encryption enabled, then allows you to test these.

The list by default has only servers within that target domain enabled, but you can optionally include other servers (for instance if a domain uses a third party for their SMTP handling).

Basically it is the web-counterpart of a tool like testssl.sh (which I have written about before).

Found while checking out how to test the MX security of a domain using [Wayback] testssl.sh as I forgot the syntax, which in retrospect is dead easy as per [Wayback] tls – How to use testssl.sh on an SMTP server? – Information Security Stack Exchange (thanks [Wayback] Z.T.!):

…

testssl.sh --mx <domain name>

works fine.

testssl.sh -t smtp <ip>:25

and

testssl.sh -t smtp <ip>:587

also work fine.

Note that not specifying the port assumes port 443, despite specifying protocol smtp. That doesn’t work.

…

Also, you might try discovery.cryptosense.com which does the same thing only better

That website is made by the cool people at [Wayback] Cryptosense.

Both are a lot easier than the alternatives described in [Wayback] Blog · How to test SMTP servers using the command-line · Halon MTA: using nslookup and dig for determining the affected hosts, using nc or telnet for testing basic connectivity, using [Wayback/Archive.is] openssl s_client to test TLS, and [Wayback/Archive.is] smtpping for measuring throughput.

In addition to the above tools mentioned in the blog, I’ve also used sendEmail (note case sensitivity), ehlo-size, and swaks.

This is what I tested:

Archive.is blog: Twitter archival is slow, so limit the number of tweets you save in it

Posted by jpluimers on 2022/03/04

[Wayback] Archive.is blog — The website has been slow for some time when…

The website has been slow for some time when archiving Twitter pages, but works fine with other websites. Is there a reason for that? Thx!

Anonymous

1. There are too many pages from Twitter in the queue, which reduces their priority (if it wasn’t for this condition, it would slow everything down)

2. Twitter API sometimes responds with “429 Too Many Requests” or other error, so it usually takes more than 1 attempt to capture the page.

I would suggest refraining from saving pages from Twitter for now, especially those people trying to save dozens or hundreds of tweets

Booting Windows 10 to the recovery console command prompt

Posted by jpluimers on 2022/03/01

I bumped into an old draft on notes on NTFS boot issues.

A while ago, I wanted to boot in the Windows 10 “Safe Mode” console, but the F8 option during the boot process was gone.

So I wondered how to get there. There seem to be a few ways, of which almost all require a functioning Windows installation. When you have one, it is relatively easy, as these options will work as summarised from [Wayback] How to open the Windows 10 recovery console:

  • Hold the physical Shift key when choosing “Reboot” in the user interface. There are various ways to get to the “Power” button:
    • in the lower right corner at the logon-screen
    • in the lower right corner at the lock-screen
    • in the lower right corner after pressing Ctrl–Alt–Del
    • in the lower left corner of the “Start” menu
  • In the Settings app, there used to be an “Advanced Startup” feature, but I could not find that any more in Windows 10 version 21H1 any more
  • From a console Window, run either of these commands (the second waits zero seconds before rebooting, the first 30)
    • shutdown.exe /r /o
    • shutdown.exe /r /o /t 0

There is also a possibility to restore the F8 functionality, but you need installation media for it. [Wayback] 3 ways to boot into Safe Mode on Windows 10 version 21H1 explains how to.

Some “notes on NTFS boot issues” links for my archive

(Note that for some of the links, only the [Wayback] ones work: link-rot of the links I saved 6 years ago)

ESXi: some notes on .vswp files; there are actually two types of them!

Posted by jpluimers on 2022/02/23

Earlier this month, I ended ESXi: editing /etc/vmware/hostd/vmInventory.xml to fix the datastore UUID for unavailable VMs part 2 with this:

A final note: I need to check out if .vswp files need to be there at all, as my ESXi servers have plenty of physical memory in order not to swap out to disk. More on that in a future blog post.

Browsing back through my blog posts, I mentioned .vswp files before, but never really dug into them:

Raamwerk ECD portal links

Posted by jpluimers on 2022/02/21

For my link archive:

Notes:

Baffled:

I basically got baffled by the (for me distracting) way the images and icons were situated on the “Cliëntportaal” page: it forced me to the more easily to grasp menu on the right, access the “Aanmelden” page, which had the wrong link.

The (non-blue, and unlike the other red links, non-red) “Log hier in bij het Cliëntportaal” link above the distracting images actually had the correct link to hetraamwerk-ecd.fierit.nl/WebCSS/Home/Login.

Archive.is is more like a thread unroll service than an archival service

Posted by jpluimers on 2022/02/14

An interesting take a while ago on [Wayback] Archive.is blog — People often compare various features of…

People often compare various features of archive.is to those of archive.org being mistaken by name similarity (and recently added “save a page” function to archive.org).

This project is different in at least two respects:

  1. We have no goal to save the entire Internet. Only manually submitted pages which may be deleted/altered soon. We are about 100x smaller than archive.org in the storage space (700TB vs. 70PB) and expenses (X,000 $/mo vs. X00,000 $/mo).
  2. The pages are not saved in their network form. Archive.today launches real browsers (not even headless) and tries to load lazy images, unroll folded content, login into accounts if prompted with login form, remove “subscribe our maillist” modals, … So archive.today is not suitable for making notarized or digitally signed snapshots.

It would be more correct to compare it with other thread unrollers.

The RSS feed of blog.archive.today is at blog.archive.today/rss

When high SEO ranking fails to give you a reliable result: IsItDownRightNow.com failed to detect the WayBack Machine outage

Posted by jpluimers on 2022/02/11

A high SEO ranking does not automatically indicate a reliable result.

When the WayBack Machine was down a while ago (it responded to traceroute UDP requests, but would not establish TCP connections on ports 80 and 443), the first Google hit for detecting down status (searching for [Archive.is] waybackmachine down – Google Search) failed miserably because it redirected web.archive.org (which fails) to http://www.archive.org (which succeeds):

IsIdDownRightNow failing to detect web.archive.org downtime

IsIdDownRightNow failing to detect web.archive.org downtime

Luckily when asking around on Twitter:

  • others were experiencing the same problem, not just in The Netherlands, but also in other countries
  • after trying a few things, the WayBack machine got backup [Archive.is] before I could try cURL.
  • I got pointed at www.uptrends.com/tools/uptime which correctly does check the right subdomain and shows it is down from many locations:
