因特网上的一个 IP 必定属于某个 AS，也就是一个自治系统。一般一个 AS 里的 IP 具有共性，比如网络质量较高或者较差，欺诈风险较高或者较低。 在使用 mtr 或者 traceroute 查看路由时，通过确认中间路由节点 IP 的 AS，可以确认路由质量。 举例说明，对于常见的 CN2 线路，通过 mtr 看到有经过 59.43.138.70，使用 whois 命令查看 IP 信息如下
~$ whois 59.43.138.70
route: 59.43.0.0/16

Entware is a modern alternative to Optware.
For those unfamiliar with Optware: it's a software repository that offers various software programs that can be installed on your router. They allow you to add new functionality to your router (provided you have the know-how to properly configure them).
Entware system library is specially modified (patched) so that standard linux files that are normally located in /etc directory are now located in /opt/etc/ directory. To simplify things let's consider /etc/passwd file. On Asuswrt-merlin it normally looks something like:
admin:x:0:0:admin:/root:/bin/sh
nas:x:100:100:nas:/dev/null:/dev/null
Hi, I am a fork from https://gist.github.com/patrickhammond/4ddbe49a67e5eb1b9c03.
A high level overview for what I need to do to get most of an Android environment setup and maintained on OSX higher Catalina and Big Sur with and without Android Studio been installed.
Considering the SDK is installed under /Users/<your_user>/Library/Android/sdk folder which is the Android Studio preferred SDK location, but it works fine under /usr/local/share/android-sdk as well, which is a location pretty much used on CI mostly.

There aren't many tutorials about this, the only tutorials I've found were about passing through entire PCIe cards to VMs, or refered to old ESXI versions (below 6.5) that used a more comprehensive desktop client instead of the web app. In v6.5, the web app was introduced and the desktop client was deprecated. You used to be able to setup RDMs in the desktop client, but with the introduction of the web console, this is no longer the case. This tutorial shows you how to pass SATA HDDs to the virtual machine on VMWare ESXI 6.5. This tutorial is partially based on VMWare's own KB and the now deprecated Forza IT blog post.
There is now an option while editing your VM's settings to add a New raw disk when you click `Add ha
With heightening concern regarding the state of internet privacy (fuelled in part by the passing of the Investigatory Powers Act in the UK), I have set up a VPN server on the virtual server I have hosted with Mythic Beasts. This uses strongSwan and certificate-based IKEv2 authentication.
Assumptions:
debian.example.com, a public IPv4 of 203.0.113.1 and a public IPv6 of 2001:db8::1meFor automated deployment of a similar setup, albeit Ubuntu-based and using ansible for deployment, I recommend you take a look at Algo VPN. I used that project as a basis for my configuration.

The original author seems to be Charles Edge, here's the original content, as pointed out by @percisely.
Note: Since this seems to be helpful to some people, I formatted it to improve readability of the original. Also, note that this is from 2016, many things may have changed, and I don't use macOS anymore, so I probably can't help in case of questions, but maybe someone else can.
After writing up the presentation for MacSysAdmin in Sweden, I decided to go ahead and throw these into a quick cheat sheet for anyone who’d like to have them all in one place. Good luck out there, and s
