VSCode SOCKS5 VPN Namespace - Arch Linux

Prerequisites

This script requires the following packages to be installed:

  • openvpn - OpenVPN client
  • dante - SOCKS5 server (provides sockd)
  • socat - Socket relay
  • curl - For testing connectivity
  • iproute2 - Network namespace management (usually pre-installed)
  • iptables - Firewall rules (usually pre-installed)

Quick Installation

Install Dependencies

sudo pacman -S openvpn dante socat curl iproute2 iptables

Usage

Connect to VPN

cd /path/to/dev-socks-isolation/linux/Arch
chmod +x connect.sh
./connect.sh

The script will prompt you for:

  • Namespace name (default: vpnspace)
  • Path to your OpenVPN config file (.ovpn)
  • Network interface (auto-detected)
  • Host IP address (auto-detected)
  • SOCKS5 ports configuration
  • DNS server (default: 8.8.8.8)
  • Whether to launch VSCode automatically

Disconnect from VPN

./disconnect.sh

Arch-Specific Notes

systemd Integration

On Arch Linux, you can optionally create a systemd service for automatic startup:

sudo nano /etc/systemd/system/vscode-vpn-proxy.service

Add:

[Unit]
Description=VSCode VPN SOCKS5 Proxy
After=network.target

[Service]
Type=oneshot
RemainAfterExit=yes
ExecStart=/path/to/dev-socks-isolation/linux/Arch/connect.sh
ExecStop=/path/to/dev-socks-isolation/linux/Arch/disconnect.sh

[Install]
WantedBy=multi-user.target

AUR Packages

If you prefer, you can install some packages from the AUR:

  • dante-server (alternative to dante)

Firewall Configuration

Arch Linux uses iptables by default. If you're using nftables, you may need to adjust the scripts or use iptables-nft compatibility layer.

Troubleshooting

Issue: "sockd: command not found"

Solution:

sudo pacman -S dante

Issue: Permission denied

Solution: Ensure your user can run sudo commands:

sudo usermod -aG wheel $USER

Issue: Cannot detect network interface

Solution: Manually specify your network interface:

ip link show
# Look for your active interface (usually starts with 'en' or 'wl')

Advanced Configuration

Custom DNS Servers

You can modify the DNS server used in the namespace by providing a different value when prompted, or by editing the script.

Multiple Namespaces

You can run multiple isolated VPN connections by using different namespace names for each connection.
