pip install shadowsocks

sudo ssserver -p 443 -k password -m aes-256-cfb --user nobody -d start

SOCKS 5 Through SSH Tunnel

# `-N`: do not execute commands
# `-D`: bind 1080 port and forward 1080 port to 22 port
# `-i`: use pre-shared key `hello.pem`
# `-p`: specify port used to connect to remote server
ssh -ND 1080 -i ~/.ssh/hello.pem <username>@<your-remote-server-ip> -p 22

Socks 5 in Terminal

Using Proxychains-ng to socksify your command

• Install proxychains-ng by running brew install proxychains-ng.
• Config /usr/local/Cellar/proxychains-ng/4.7/etc/proxychains.conf, modify the following parameters.

[ProxyList]
socks5 127.0.0.1 1080

• Add proxychains4 to the front of every command, e.g. proxychains4 curl ipecho.net/plain

Also works for Application like Google Chrome while Safari does not work, try proxychains4 /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome . But this might slow down Chrome.

You can also use dsocks for mac(which does not work for me), tsocks for linux.

Using Unix Proxy Environment Variable

Add this script to ~/.bash_profile.

export http_proxy=socks5://127.0.0.1:1080
export https_proxy=socks5://127.0.0.1:1080

Config curl to use SOCKS5(Also works for homebrew)

Add the following line to ~/.curlrc. Since homebrew use curl to download the package, this will also enable homebrew to use SOCKS5.

socks5 = "socks5://127.0.0.1:1080"

There are no environment variables for SOCKS5 proxy servers in unix, so in order to use SOCKS5 in other utilities, check the man pages for existing tools to see if they have a configuration option for a SOCKS5 proxy and whether they have a configuration file that the configuration can be added to.

Config git to use SOCKS5

• For https:// and http://(e.g. http://github.com, https://github.com), run the following script.

git config --global http.proxy 'socks5://127.0.0.1:1080'
git config --global https.proxy 'socks5://127.0.0.1:1080'

• For git://(e.g. git://github.com), run git config --global core.gitproxy 'socks5://127.0.0.1:1080'
• For ssh(e.g. [email protected],ssh://[email protected]), add ProxyCommand nc -x localhost:1080 %h %p to ~/.ssh/config file.

git config --global is stored in ~/.gitconfig while local config settings is in ./.git/config. To remove a configuration, e.g. run git config --global --unset core.gitproxy.
