The hodgepodge of proxy configuration

My topic in a seminar at a ramdom time in the future.

Also, HAPPY PI DAY!

The hodgepodge of proxy configuration

disclaimer

This lecture only introduces proxy configuration method in different context from a university students' perspective. It won't provide any information about proxy sources, please STFW on your own.

Introduction

Proxy is a server that acts as an intermediary for requests from clients seeking resources from other servers. A client connects to the proxy server, requesting some service, such as a file, connection, web page, or other resource available from a different server and the proxy server evaluates the request as a way to simplify and control its complexity.

Due to the inherent feature of our country, we need to use proxy to access some foreign websites or speed up the working efficiency when setting up the environment. This lecture will introduce the proxy configuration method in different context.

Basic Assumptions

Table of Contents

Linux/Mac shell

alias setproxy='export http_proxy="http://127.0.0.1:7897";export https_proxy="http://127.0.0.1:7897";export socks_proxy="http://127.0.0.1:7897"'
alias unsetproxy='unset http_proxy;unset https_proxy;unset socks_proxy'
source ~/.bashrc (~/.zshrc etc.)

Windows shell

# 设置代理
netsh winhttp set proxy 127.0.0.1:7897
# 取消代理
netsh winhttp reset proxy
# 查看代理
netsh winhttp show proxy

$Env:http_proxy="http://127.0.0.1:7897";$Env:https_proxy="http://127.0.0.1:7897"
  1. Open Settings -> Network & Internet -> Proxy
  2. Set Manual proxy setup to On
  3. Fill in the Address and Port with localhost and 7897 respectively

Vmware

assume you are using NAT mode and you enabled allow LAN in your proxy software.

  1. check your ifconfig/ipconfig result of vmnet8
vmnet8: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.18.1  netmask 255.255.255.0  broadcast 192.168.18.255
        inet6 fe80::250:56ff:fec0:8  prefixlen 64  scopeid 0x20<link>
        ether 00:50:56:c0:00:08  txqueuelen 1000  (Ethernet)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 103  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
  1. set proxy in your vm
export http_proxy="http://192.168.18.1:7897"
export https_proxy="http://192.168.18.1:7897"
export socks_proxy="http://192.168.18.1:7897"

VirtualBox

  1. set your network adapter to Host-only Adapter
  2. an interface named vboxnet0 or other will be created
  3. ifconfig/ipconfig to check the ip address
vboxnet0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.56.1  netmask 255.255.255.0  broadcast 192.168.56.255
        inet6 fe80::800:27ff:fe00:0  prefixlen 64  scopeid 0x20<link>
        ether 0a:00:27:00:00:00  txqueuelen 1000  (Ethernet)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 33  bytes 3289 (3.2 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
  1. set proxy in your vm, in this way you can also solve the problem of not able to access the internet in your vm
export http_proxy="http://192.168.56.1:7897"
export https_proxy="http://192.168.56.1:7897"
export socks_proxy="http://192.168.56.1:7897"

browsers

  1. Open Settings
  2. Search Proxy and click Open your computer's proxy settings (Chrome/Edge), Firefox can be configured directly
  3. Fill in the Address and Port with localhost and 7897 respectively
  1. Install the plugin
  2. Options
  3. New profile (proxy profile, enter your profile name)
  4. select DIRECT -> HTTP
  5. Fill in the Address and Port with localhost and 7897 respectively
  6. Apply changes

vscode/code - OSS/vscodium

Settings -> search proxy -> fill in the Address and Port with localhost and 7897 respectively

Git

git config --global http.proxy http://localhost:7897
git config --global https.proxy https://localhost:7897

git config --global --unset http.proxy
git config --global --unset https.proxy

ssh

Host github.com
    HostName ssh.github.com
    #HostName github.com
    port 443
    IdentityFile ~/.ssh/id_rsa
    User git
    ProxyCommand nc -v -x 127.0.0.1:7897 %h %p

curl/wget

default to use http_proxy and https_proxy environment variables, otherwise

curl -x localhost:7897 http://example.com
wget -e http_proxy=localhost:7897 http://example.com

apt/yum/pacman

changing the mirror is a better choice (STFW)

/etc/apt/apt.conf.d/proxy.conf
Acquire::http::Proxy "http://proxy-IP-address:proxyport/";
Acquire::http::Proxy "http://proxy-IP-address:proxyport/";

/etc/yum.conf
proxy=http://localhost:7897

# delete either of the following lines, and configure the proxy in curl/wget
# setting http_proxy and https_proxy environment variables is also a good choice

/etc/pacman.conf
#XferCommand = /usr/bin/curl -L -C - -f -o %o %u
#XferCommand = /usr/bin/wget --passive-ftp -c -O %o %u

docker

sudo mkdir -p /etc/systemd/system/docker.service.d
sudo touch /etc/systemd/system/docker.service.d/proxy.conf

[Service]
Environment="HTTP_PROXY=http://localhost:7897/"
Environment="HTTPS_PROXY=http://localhost:7897/"
Environment="NO_PROXY=localhost,127.0.0.1,.example.com"

sudo systemctl daemon-reload
sudo systemctl restart docker

   }
 }
}

docker build . \

    -t your/image:tag

pip

pip install --proxy http://localhost:7897 package
pip install --proxy https://localhost:7897 package

or change the mirror to a domestic one

npm

# 设置代理
npm config set proxy http://127.0.0.1:7897
npm config set https-proxy http://127.0.0.1:7897
# 取消代理
npm config delete proxy
npm config delete https-proxy

or

~/.npmrc

proxy=http://127.0.0.1:7897
https-proxy=http://127.0.0.1:7897

proxychains4

# /etc/proxychains.conf


[ProxyList]
# add proxy here ...
# meanwile
# defaults set to "tor"
# socks4 	127.0.0.1 9050
http 127.0.0.1 7897
socks5 127.0.0.1 7897

BELOW ARE F**KING JAVA SERIES, it is hard to configure the proxy in java, I mostly use mirrors.

gradle

gradle.properties

systemProp.http.proxyHost='localhost'
systemProp.http.proxyPort='7897'
# 过滤不使用代理的域名
systemProp.http.nonProxyHosts=*.example.com
systemProp.https.proxyHost='localhost'
systemProp.https.proxyPort='7897'
# 过滤不使用代理的域名
systemProp.https.nonProxyHosts=*.example.com

maven

I choose to change the mirror to a domestic one

mill

doesn't support proxy, use proxychains4 to force it

alias mill='proxychains4 mill'
