Bypass DPI on Linux

UPDATE as of 08/06/24  Bypass DPI on Arch Hyprland

Deployed via https://github.com/mylinuxforwork/dotfiles

END UPDATE

Following below is an implementation of some DPI bypass methods.The program is a local SOCKS proxy server.

A SOCKS proxy is a tool that allows you to route your internet traffic through a remote server, providing you with anonymity and the ability to bypass restrictions. It acts as a mediator between your device and the websites or services you want to access. When you send a request to access a website, the request is first sent to the SOCKS proxy server.

The proxy server then forwards your request to the website on your behalf, using the SOCKS protocol. This protocol enables the proxy server to establish a TCP connection with the website and pass the data between the two. By using a SOCKS proxy, your real IP address is hidden, and your network traffic appears to be originating from the proxy server, enhancing your online privacy. Additionally, they support various authentication methods, ensuring secure communication between your device and the proxy server.

Another attempt

Final step would be to create service ciadpi.serivce , enable it and restart the box to make sure

$ cat ciadpi.service

[Unit]

Description=Script Daemon For Test User Services

[Service]

Type=simple

#User=

Restart=on-failure

StandardOutput=file:%h/log_file

[Install]

WantedBy=default.target


Next step:


$ sudo cp ciadpi.service  /etc/systemd/user/

$ systemctl --user daemon-reload

$ systemctl --user start ciadpi.service

$ systemctl --user enable ciadpi.service


boris@fedora:~$ systemctl --user status ciadpi.service
