Linux

You have two ways of installing WARP on Linux, depending on the distro you are using:

• Find the latest WARP client in the package repository ↗.
• Install the cloudflare-warp package that suits your distro:
  • apt-based OS (like Ubuntu): sudo apt install cloudflare-warp.
  • yum-based OS (like CentOS or RHEL): sudo yum install cloudflare-warp.

Using WARP

The command line interface is the primary way to use WARP.

To connect for the very first time:

1. Register the client warp-cli registration new.
2. Connect warp-cli connect.
3. Run curl https://www.cloudflare.com/cdn-cgi/trace/ and verify that warp=on.

You can use warp-cli mode --help to get a list of modes to switch between. For example:

• DNS only mode via DoH: warp-cli mode doh
• WARP with DoH: warp-cli mode warp+doh

You can switch the protocol that WARP uses to route traffic from the device to Cloudflare.

• WireGuard: warp-cli tunnel protocol set WireGuard
• MASQUE: (default) warp-cli tunnel protocol set MASQUE

For information on WireGuard versus MASQUE, refer to our blog post ↗.

The Linux client supports all 1.1.1.1 for Families modes, in either WARP on DNS-only mode:

• Families mode off: warp-cli dns families off
• Malware protection: warp-cli dns families malware
• Malware and adult content: warp-cli dns families full

A complete list of all supported commands can be found by running:

warp-cli --help

Feedback

You can find logs required to debug WARP issues by running sudo warp-diag. This will place a warp-debugging-info.zip file in the path from which you ran the command.

To report bugs or provide feedback to the team use the command sudo warp-diag feedback. This will submit a support ticket.
