SSH Access

Warning!

This guide will teach you how to log into your reMarkable from your computer. There is a separate article on how to transfer files.

Finding your Password and IP Address

Connect your reMarkable to Wi-Fi or via USB (or both), and you will find your SSH password and IP address (or addresses) in the settings menu.

  • Settings > Help > Copyrights and licenses > General information (scroll down)

Connecting via SSH

On Windows, you have to first enable the official OpenSSH client. Then open a command line prompt (Windows Key + R, type 'cmd', press Enter).

On MacOS and Linux, you already have an SSH client, so just open Terminal.

If you connected your reMarkable via USB, enter the following command:

ssh root@10.11.99.1

If you connected your reMarkable via Wi-Fi, the IP will be assigned by your router and can vary greatly depending on your network configuration. Usually it takes the form below. Replace x with the appropriate number.

ssh root@192.168.0.x

Then enter your reMarkable password. The password will not be shown as you type it.

Tips

SSH Config File

You can set up an alias that is easier to remember by adding the following lines to the ~/.ssh/config file on your computer:

host rem
    Hostname 10.11.99.1
    User root
    Port 22
    IdentityFile ~/.ssh/id_rsa

The file above will allow you to login by entering ssh rem (instead of ssh root@10.11.99.1) and transfer files with scp <source> rem:<destination>. You can replace the word “rem” with an alias of your choice.

Passwordless Login with SSH Keys

The reMarkable uses dropbear (via BusyBox) for its SSH server and supports ssh-rsa keys. Keys save your from entering the randomly generated password over and over again.

On your computer, generate an SSH public and private key pair with

ssh-keygen

To use the default location and no passphrase, just press Enter three times.

With ssh-copy-id

To send the public key id_rsa.pub from your computer to the reMarkable use

ssh-copy-id root@10.11.99.1

Without ssh-copy-id

On your reMarkable, create an .ssh directory

mkdir -m 700 ~/.ssh

Exit the SSH session and send the host key from your computer to the reMarkable

scp ~/.ssh/id_rsa.pub root@10.11.99.1:~/.ssh/authorized_keys

On your reMarkable again, set the permissions of authorized_keys to owner read and write

chmod 600 ~/.ssh/authorized_keys

OpenSSH 8.8 and later

Starting with OpenSSH 8.8 ssh-rsa keys are disabled by default, so you will get the following error when trying to log into your reMarkable.

Unable to negotiate with 10.11.99.1 port 22: no matching host key type found. Their offer: ssh-rsa

You can check your OpenSSH version with ssh -V

To allow ssh-rsa keys, add the following lines to your SSH Config file.

  PubkeyAcceptedKeyTypes +ssh-rsa
  HostKeyAlgorithms +ssh-rsa
