Run this command to update the initial ramdisk file: update-initramfs -u If you are using an AWS instance, copy the public-key of your instance into this authorized_keys file. The id_rsa file is the private key where you will need to copy to the client that will login by ssh. The id_rsa.pub file is the public key where you will need to copy to the remote system as described in #2 above. This command will generate two files: ~/.ssh/id_rsa If you don’t have an ssh-key pair, you can create one using the ssh-keygen command ssh-keygen Get your public ssh-key and copy it to this file on your remote system: /etc/initramfs-tools/root/.ssh/authorized_keys Install dropbear apt-get install dropbear You will need access to GitHub to download the scripts. This can help in troubleshooting the script in case you encounter problems. It is recommended to try the manual steps first so that you will have an understanding of the underlying process. The guide shows both a manual process and a script to automate the steps. The idea can be easily applied to other distributions like CentOS or RHEL. The guide is created for Ubuntu and Debian systems and using DHCP to establish network access.

Once you can login by ssh into the initrd, you can then supply the password to decrypt and boot up the system.īelow is a step-by-step guide on how to install an ssh server in the initial ramdisk, login to it, and enter the password to boot up your encrypted Linux system. If you cannot install a remote console or if your system doesn’t allow one, for example, instances in Amazon Web Services (AWS), you can still obtain remote access to enter the password by installing an ssh server in the initial ramdisk. If your system is remote or doesn’t have console access, you will need to find a way to get remote access to the console. If you use cryptsetup to encrypt your Linux root file system, the default setup requires console access to enter the password and boot up the system.
