小張的技術筆記

Overview

• This is a simple walkthough on how to host your own Jitsi server
• Detailed configuration will not be included in this paragraph, please check out their official documentation.
• I’m using Ubuntu 18.04 hosted on AWS, with Let’s Encrypt certificate, and Nginx preinstalled.

Issues I’ve encounterd

<!-- Make sure proxyPort is set to 443 -->
<!-- Set this in Host section -->
<Valve className="org.apache.catalina.valves.RemoteIpValve"

Something to mention

So, after two years of usage, the joints on my WI-1000X cracked. Rep at Sony repain station states that, this kind of malfunction is not a “malfunction”, instead it’s just a asethetic problem, which is not covered by the warranty.
In order to fit the criteria, you must have certain functions that is not working, for example, one of the earphone is not working properly.

Recently, I’m seeing massive weird HTTP requests on our company production servers, most of them are using weird User-Agent
For example:

• LiebaoFast (50%~60%)
• MicroMessenger
• Kinza
• Some weird random Huawei cellphone
• New android versions with super old Chrome
• Having zh_CN in their User-Agent string

• This is just a simple walkthrough of the installation process
• Installation will be using OpenCore instead of Colver

Prerequisite

• ASUS VC60
• BCM Wifi card (If you want to have proper wifi support)
