Foreword: Last week, I went back to my hometown to celebrate the Chinese New Year for a few days, so I didn’t have much time to write articles (actually, I had 2 articles in progress, but they were stuck in the middle and needed time to study and experiment), so this week’s content can be written in a short but necessary article to highlight the key knowledge points: Clou…

Attack Scale From 3am to 6am today, we encountered a wave of DDoS attacks, which is the highest record so far. It is worth recording: Number of attack requests: Attack bandwidth: Number of attackers: Source of attackers: Top 3 IP addresses and number of attack requests that initiated the attack: Attack type This attack…

A few days ago, I saw that the devices running TailScale were running all kinds of strange versions of TailScale. Due to my obsessive-compulsive disorder, I changed the version of TailScale for all the devices running TailScale (except Qnap NAS and OpenWRT, because these two official versions are currently...

However, because I just finished the final work of the data migration after purchasing the hard disk yesterday, I am in the mood to optimize the demonstration site...

Foreword For the analysis of the needs of general users for NAS, please refer to my other article (A series of tricks on how to choose the NAS that suits you best), so I won’t go into details here. The main target of this article is people who need a lot of storage space on NAS, including but not limited to: people who have a hobby of collecting…

Foreword: I have been reading about the knowledge points related to how to solve the Ajax cross-domain problem caused by the browser homology policy restrictions. However, when I was thinking about how to write an article to record the relevant knowledge points, I found that it was difficult to explain it clearly from an angle that is easy for ordinary people to understand, and it was even difficult to give examples. Thinking back...
