Wifi on Ubuntu 18 server

TLDR

Install wpasupplicant
Turn on wifi radios: sudo nmcli radio wifi on
Check your devices are recognised even if they're not "managed": sudo iwconfig
Check your wifi (here called "wlp3s0") is capable of detecting nearby routers: sudo iwlist wlp3s0 scan
Configure netplan by dropping a file called 01-netcfg.yaml into /etc/netplan/ or edit existing file there. See example below.
netplan try, netplan generate, netplan apply.

AVR 8bit HomeBrew installation for macOS

In case you have a trouble for updating the tap, perform uninstalling of the related tools and osx-cross/avr tap:

brew remove avr-binutils avr-gcc
brew untap osx-cross/avr

For installing the tap, do the following:

##ss-redir 的 iptables 配置(透明代理)

透明代理指对客户端透明，客户端不需要进行任何设置就使用了网管设置的代理规则

创建 /etc/ss-redir.json 本地监听 7777 运行ss-redir -v -c /etc/ss-redir.json

iptables -t nat -N SHADOWSOCKS
# 在 nat 表中创建新链
iptables -t nat -A SHADOWSOCKS -p tcp --dport 23596 -j RETURN
# 23596 是 ss 代理服务器的端口，即远程 shadowsocks 服务器提供服务的端口，如果你有多个 ip 可用,但端口一致，就设置这个
