A modern, automated, and user-friendly Linux CLI tool for smart and live optimization of MTU and MSS on your network interfaces and VPN tunnels.
It continuously finds the best values for your network by testing and tuning in real-time — with full support for jumbo frames and interactive, colored menus.

Copy and paste this command in your terminal (Debian/Ubuntu & derivatives):

bash <(curl -fsSL https://raw.githubusercontent.com/Shellgate/mtuso/main/mtuso.sh)

• Auto-detects and sets the best MTU/MSS based on latency, packet loss, and throughput
• Works with all interfaces and VPN tunnels
• Jumbo frame support (MTU up to 9000)
• Live and interactive menu: Start, pause, resume, disable, uninstall, reset
• Beautiful CLI UI with colors and status display
• Auto-install script and systemd integration: Runs as a service if enabled
• No manual config needed – just run and enjoy optimal network performance!

After installation, simply run:
