Notes

Sad to hear that Jérôme Jutteau, the original author of Jirafeau, decided not to do any further development of his tool:

End of maintenance

Since I made some pull requests to this project, I'm currently thinking about what to do with them.

A consultant once told me that you can run WSUS on SQL Express instead of WID and that it performs better on SQL Express than on WID:
Install WSUS with a SQL Server database

I tried it and and I have to say: Don't do it. Yes, it seemed to perform better, but since SQL Express' databases are limited to 10 GB, WSUS will suddenly stop working, because the database files reached the limit. It is OK to use a licensed SQL Server because it is not affected by the limited file size.

WID is fine. It seems to be much more stable on more recent Windows versions.

Again an (not that) old photo of a RMV ticket machine. This time, a HTTPS connection was not private:

As I already said, the upper display normally shows advertisements and upcoming train departures. I guess the HTTPS certificate was expired here.

In German, this error message is kind of funny in this context, because it says "Dies ist keine sichere Verbindung" meaning "This is no secure connection". In this context, the "connection" could also mean that the train connection is not secure.

I posted this some time ago on my Mastodon page, but forgot to post it here.

I tried to access devices on a different subnet connected to an Aruba Instant On switch. It didn't work. It was a different IP subnet, but the same VLAN.

As it turned out, there is a feature named "Network Protection". It seemed to filter out everything from other subnets. After disabling it, everything was fine.

Recently, I moved a shared folder from one Synology NAS to another. Accessing the folder using Windows 10 and WebDAV resulted in the following error:

The folder you entered does not appear to be valid. Please choose another.

(In german: Der eingegebene Ordner ist ungültig. Wählen Sie einen anderen Ordner.)

It worked on Windows 11, so it seemed to be a problem with Windows 10.

As it turned out, both NAS systems used the Modern TLS profile. But one NAS had DSM 6 and the other one DSM 7. In DSM 7 the Modern profile only supports TLS 1.3 (see here) whereas in DSM 6, the Modern profile allows TLS 1.2. But in Windows 10, TLS 1.3 is disabled per default.

Because TLS 1.2 is still secure and the affected Windows 10 computers were not ours, we switched to the Intermediate TLS profile. Now the Windows 10 computers were able to access the shared folder using WebDAV.
