| - | ===== Connecting via SSH ===== | ||
| - | |||

| - | |||
| - | 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 '' | ||
| - | |||
| - | < | ||
| - | 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 '' | ||
| - | |||
| - | < | ||
| - | host rem | ||
| - | Hostname 10.11.99.1 | ||
| - | User root | ||
| - | Port 22 | ||
| - | IdentityFile ~/ | ||
| - | </ | ||
| - | |||
| - | The file above will allow you to login by entering '' | ||
| - | |||
| - | ==== Passwordless Login with SSH Keys ==== | ||
| - | |||
| - | The reMarkable uses [[https:// | ||
| - | |||
| - | On your computer, generate a public and private SSH key pair with | ||
| - | |||
| - | < | ||
| - | ssh-keygen | ||
| - | </ | ||
| - | |||
| - | You can leave the location blank to use the default and leave the passphrase blank. | ||
| - | |||
| - | === With ssh-copy-id === | ||
| - | ssh-copy-id may not work on newer reMarkable releases as ssh-copy-id places the keys in ''/ | ||
| - | |||
| - | To send the public key '' | ||
| - | |||
| - | < | ||
| - | ssh-copy-id root@10.11.99.1 | ||
| - | </ | ||
| - | |||
| - | === Without ssh-copy-id === | ||
| - | |||
| - | On your reMarkable, create an '' | ||
| - | |||
| - | < | ||
| - | mkdir -m 700 ~/.ssh | ||
| - | </ | ||
| - | |||
| - | Exit the SSH session and send the host key from your computer to the reMarkable | ||
| - | < | ||
| - | scp ~/ | ||
| - | </ | ||
| - | |||
| - | On your reMarkable again, set the permissions of '' | ||
| - | < | ||
| - | chmod 600 ~/ | ||
| - | </ | ||
| - | |||
| - | ==== OpenSSH 8.8 and later ==== | ||
| - | |||
| - | Starting with OpenSSH 8.8 ssh-rsa keys are [[https:// | ||
| - | |||
| - | < | ||
| - | 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 '' | ||
| - | |||
| - | Some Linux distros like Fedora 33 have also disabled weaker ssh-rsa keys independently of OpenSSH. That means you could face the same issue on OpenSSH versions lower than 8.8, depending on the distro you are on. | ||
| - | |||
| - | To allow ssh-rsa keys, add the following lines to your [[# | ||

| - | HostKeyAlgorithms +ssh-rsa | ||
