🛜 Linux Proxy Applier - IIITA

Simple scripts to quickly set and remove system-wide proxy settings on GNU/Linux systems.

⚠️ Please read carefully before using.

---

📋 Before You Start

• Backup your /etc/environment file:

  sudo cp /etc/environment ~/environment.backup

Do not run these scripts using sudo.

⚠️ Currently tested and supported only on Debian-based distributions (Ubuntu, Kubuntu, Pop!_OS, Linux Mint, etc.) and on Arch-based distributions (Arch, Manjaro, EndeavourOS).
Other distros like Fedora, or openSUSE are not yet supported.

🚀 How to Use

• Go to the directory for your distro (e.g., Arch/ or Debian/)
• Go to the directory that your system is currently using
• Set Proxy:

  ./apply_proxy
  

You’ll be asked to enter the proxy hostname.

• Remove Proxy:

  ./remove_proxy
  

🖥️ If you are using KDE Plasma, enable: System Settings → Network → Settings → Proxy → Use system proxy configuration

🌎 Run Scripts from Anywhere

• Instead of Distro, use your current distro, Arch/ or Debian/
• If you want to use apply_proxy and remove_proxy globally, add them to your ~/.local/bin/:

  mkdir -p ~/.local/bin
  
  curl https://raw.githubusercontent.com/Surya-Raghuram/Linux-Proxy/main/linux-proxy/{Distro}/apply_proxy > ~/.local/bin/apply_proxy && chmod +x ~/.local/bin/apply_proxy
  curl https://raw.githubusercontent.com/Surya-Raghuram/Linux-Proxy/main/linux-proxy/{Distro}/remove_proxy > ~/.local/bin/remove_proxy && chmod +x ~/.local/bin/remove_proxy
  

✅ After this, you can run apply_proxy or remove_proxy from any directory!

🔍 What the Scripts Modify When you apply proxy, the script updates:

• /etc/environment
  

• It also updates some other popular packags that are used, the packages it supports are:
  • apt/ pacman
  • snap
  • git
  • npm

⚡ Important Warnings

Modifying /etc/environment is risky. Always keep a backup.

Understand what the script does before running it.

If something goes wrong, it's on you — use responsibly.

📝 TODO

• Add support for Arch-based distros (Manjaro, EndeavourOS, Arch Linux)
• Add support for Fedora/RHEL/CentOS (DNF/YUM proxy configs)
• Add GNOME/KDE desktop environment proxy integration
• Export proxy settings in shell configs (~/.bashrc, ~/.zshrc, etc.)
• Add dry-run mode + rollback option for safety
• Provide .deb and .rpm packages for easier installation
