![]() The last, hardest, and least "secure" is to configure the "host" ChromeOS run an SSH server, but this requires removing a lot of the security protections that make Chromebooks a really solid development platform. The second easiest is Crouton which requires Developer mode, but can still maintain a lot of the system security features. The easiest is to enable SSH in Crostini and set up a port forward using the new options in the latest ChromeOS releases. You can use this if the Terminal no longer starts the container and you want to get onto it.)Īs you mentioned there are several options for accessing ChromeOS devices depending on what your goal is. (There is a way to manually start a container with CROSH and then use termina and then lxc. If the container is not started from the Terminal application, it is not possible to start port-forwarding. The Linux containers can break and not startup from the Terminal application. If you do get it working, remember to backup your Linux container. You have to manually start forwarding in the Linux settings tab after you have stopped the container. It is an inconvenience but the port-forwarding is not restored when you stop and then start the container. What you can do is install your own SSH daemon and run it on a different port, (I use 2223) and use the port-forwarding feature in the host OS, given above. This does something for ChromeOS to start the container and is an SFTP-only server. There is already an SSH daemon running on port 2222. It can now forward ports, but only to non-privileged port numbers (1024 and above). See the “Harden SSH Access” section of Setting Up and Securing a Compute Instance guide to review how to secure SSH on the server’s side, and the Advanced SSH Server Security for more information on making it even more secure.There have been some changes to the Linux container. Now that you can connect from your Linux machine to the Linode over SSH, save not only time but also make the connection even more secure by using SSH public key authentication. See the guide Troubleshooting SSH for assistance. If SSH isn’t connecting you to your Linode, it is possible that it needs to be looked at on the server. ![]() Going Further Troubleshooting SSH Connection Issues Type x to close the tab, r to reconnect to the same server, or c to be presented with the Connection Dialog window, allowing you to manually type in the details for a new connection. (R)econnect, (C)hoose another connection, or E(x)it? The terminal then shows something similar to: logout Ending the SSH SessionĪfter you are done, log out of the session by typing exit. Getting to know these commands will help you navigate around your server. This includes many of the basic Linux commands, such as ls, cd, rm, and those covered in Using the Terminal guide. You can now run any commands that you have available on that server. The command prompt should show the username and hostname configured for the server. Once you have successfully connected, the Secure Shell extension displays a terminal that’s using the remote shell environment for the server. Type in the correct password for the remote user and press enter. Open Chrome and type the following into the URL/address bar, replacing with the username of the remote user and with the IP address or domain name of the remote server.Īccept the prompt by entering yes, which results in a one-time warning that is similar to: Warning: Permanently added 'example' (ECDSA) to the list of known hosts. Open the Secure Shell extension on the Chrome Web Store and click Add to Chrome.Ī confirmation window may appear notifying you of the actions and permissions the extension will use. You can skip this step if using ChromeOS. Install the Chrome web browser on your local Windows, Mac, or Linux computer. If you wish to deploy a new server, follow the Creating a Compute Instance guide to create a Linode. ![]() Most Linux distributions have an SSH server preinstalled. Before You BeginĮnsure you have a Linux system with an SSH server (like OpenSSH) installed. This article covers the basics of connecting to a remote server (such as a Linode) over SSH using the Secure Shell extension available on ChromeOS or any Chrome web browser running on Windows, Mac, and Linux. This is a common task when administering a website, hosting environment, or even a Raspberry Pi or Arduino system. When most people refer to SSH, it is within the context of connecting from a local computer to a remote server. SSH ( secure shell) is used for secure communication between devices.
