Set proxy for CMD/Powershell/Terminal/Git

CMD

proxy_type=<protcol>://<username>:<password>@<server>:<port>

For examples:

set http_proxy=http://127.0.0.1:PORT
set https_proxy=http://127.0.0.1:PORT

set http_proxy=socks5://127.0.0.1:PORT
set https_proxy=socks5://127.0.0.1:PORT

# -v verbose (print errors/warnings while in event loop)
# -vv very verbose (also print client commands/reponses)
# -vvv extremely verbose (also print internal state transitions)
# -k ignore the certificate check

To clear the proxy:

set http_proxy=
set https_proxy=

Powershell

Very similar to cmd, here’s the examples:

$Env:http_proxy="http://127.0.0.1:PORT";
$Env:https_proxy="http://127.0.0.1:PORT";

Additionally, you can add these lines of command to the Powershell’s profile, the follow command will create and open a new profile. The commands in the profile file will run automatically when Powershell starts.

if (!(Test-Path -Path $PROFILE )) { New-Item -Type File -Path $PROFILE -Force }
notepad $PROFILE

Terminal

Examples:

export http_proxy="http://127.0.0.1:PORT/"
export https_proxy="https://127.0.0.1:PORT/"

export http_proxy="socks5://127.0.0.1:PORT/"
export https_proxy="socks5://127.0.0.1:PORT/"

export all_proxy="socks5://127.0.0.1:PORT/"

You can edit your ~./bashrc or ~/.zshrc to easily set proxy in terminals, as an example below:

alias setproxy="export http_proxy=http://127.0.0.1:PORT/; export https_proxy=http://127.0.0.1:PORT/; echo 'Set proxy successfully'"
alias unsetproxy="unset http_proxy; unset https_proxy; echo 'Unset proxy successfully'"

source ~/.bashrc to take effect.

Proxychains

Proxychains is a tool that forces any TCP connection made by any given application to follow through proxy like TOR or any other SOCKS4, SOCKS5 or HTTP(S) proxy.

Proxychains-ng, the ng standing for next generation, is an enhanced iteration of the defunct proxychains project. It offers improved functionality and enhanced compatibility. Except in cases where proxychains is more suitable due to limitations, proxychains-ng is generally advised.

Installation

Proxychains-ng already comes pre-installed in most distributions. You can check by entering the command:

proxychains4

However Proxychains-ng isn’t installed on distributions like Ubuntu. You can install it with apt.

sudo apt update
sudo apt install proxychains4

You can install proxychains on Mac OS X with an homebrew. You have to download unofficial brew formula for proxychains4: https://gist.github.com/allenhuang/3792521.

git clone git://gist.github.com/3792521.git gist-3792521
brew install --HEAD gist-3792521/proxychains4_formula.rb
# The default config file will be located in /usr/local/etc/proxychains.conf

brew install proxychains

To run current source code version:

git clone https://github.com/haad/proxychains.git
cd proxychains

# needs a working C compiler, preferably gcc
./configure
make
sudo make install

Configure Proxychains

Open the proxychains configuration file using a text editor.

sudo vi /etc/proxychains4.conf

Add proxies to the bottom of the file (under [ProxyList]). Ensuring they are in the format of . If you are using authentication, add these next .

You can also configure how proxychains uses the list of proxies you’ve provided. These can be dynamic, strict, round-robin, or random chains.

• Dynamic Chain: Attempt to use the proxies in the listed order. However, if one fails, it’ll skip it and move on to the next one.

• Strict Chain: Every proxy is used in the listed order, from the first to the second, third, and so on. If one proxy fails, the entire connection fails.

• Round-Robin Chain: The chained proxies are used circularly to distribute the connection amongst the provided proxies. Each connection request goes to the next one in the list, and once it reaches the end, it starts over again at the beginning.

• Random Chain: Selects proxies for each connection in a random order. It does not use the proxies in order and provides a unique path through each listed proxy.

Use Proxychains

For example, to use proxy with curl, you just need to enter the following command:

proxychains4 curl

Git

Set globally:

git config --global http.proxy http://127.0.0.1:PORT
git config --global https.proxy https://127.0.0.1:PORT

git config --global http.https://github.com.proxy socks5://127.0.0.1:PORT
git config --global https.https://github.com.proxy socks5://127.0.0.1:PORT

Only set for Github:

git config --global http.https://github.com.proxy https://127.0.0.1:PORT
git config --global https.https://github.com.proxy https://127.0.0.1:PORT

Unset proxy:

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

Check current proxy:

git config --global -l

You can write your configurations into .gitconfig:

vi ~/.gitconfig

[http]
proxy = socks5://127.0.0.1:PORT
proxy = http://127.0.0.1:PORT
 
[https]
proxy = socks5://127.0.0.1:PORT
proxy = https://127.0.0.1:PORT

To take effect:

git config -l --global
