nutshell 重生——不断否定、修改才能让知识真正成为技能

Posted on One min read

我建立这些 repo 的初心就是方便自己，nutshell——作为文档的集大成者——更应该做好表率。这次彻底翻新，就是要把那些用不到的都清理掉，让 nutshell 真正成为我遇到问题时的好帮手。

把一些是在不忍心删除的放在这里，比如

In /etc/passwd, the 3rd field indicates the number of days (since 1970-01-01) since last password change, empty indicates never and 0 forces user to change.

当初学习的时间觉得“好厉害啊”，但又完全用不上（我又不是管理员）。

怎么只有这一项呢？也许是后来看开了之后都删了吧。

privoxy 太长了，就放到最后吧。感谢V2Ray，不需要专门写程序来 turn socks proxy into http proxy。（后来发现 haproxy 切换 proxy 的功能也可以实现，但有时要重新加载网页，还是不如只用一个 proxy 来得方便。）

privoxy is pretty useful when some program can’t use socks proxy, but still need to bypass GFW.

sudo vim /etc/privoxy/shadowsocks.config

user-manual /usr/share/doc/privoxy/user-manual
logfile logfile
listen-address  127.0.0.1:1081
listen-address  [::1]:1081

forward-socks5 / 127.0.0.1:1080 .

sudo vim /etc/systemd/system/privoxy-ss.service

  • listen-address can be retricted to the computer’s real IP (I have used this feature to temporarily let other people inside NKU LAN break GFW.).
  • forward-socks5 .github.com 127.0.0.1:1080 . can use shadowsocks only for certain domain and direct connect for others.
