HOWTO: Start an SSH Session from ChromeOS

My lovely fiance knows how much I love my toys and opted to get me one of the new ARM based Chrome books as an early Christmas present. I'd been talking a lot about the device because the hardware on it is fairly fantastic for the 250$ price tag it comes with. At any rate - I'll be writing up a full formal review of the device at a later date (once I have had a chance to use it more). I also plan to create Bodhi ARM images for the device once time permits.

Until I have time to get Bodhi running on the device though I am stuck with ChromeOS - which while interesting leaves some to be desired. At the very least I need my operating system to have a web browser and a ssh connection - the former ChromeOS provides very obviously (the whole OS is one giant web browser). Getting an SSH connection from the device was not as straight forward however. I started by searching for a terminal emulator on the Chrome Web Store. As you can see - there are a few options there, but none of them would successfully open a ssh connection to my build servers from my Chrome Book.

A little bit off searching on the Linux answer machine yielded me a proper solution from the comment section of a posting. To get a SSH connection on ChromeOS you do not need to add any software! Pressing the key combination:


Will open a browser based terminal emulator called "crosh" in a new tab of your browser on ChromeOS. Now my build servers are accessed from a non-default ssh port. On any Debian based operating system I would use the following to connect:

ssh -p username@myserveraddy.com

The ssh client on ChromeOS doesn't seem to like the -p argument for a port number though. I found two ways to connect to a ssh server using a different port number. The first is simply:

ssh username@myserveraddy.com

The second is a whole lot less intuitive. In order you type:

host myserveraddy.com
user username

Have fun sshing from ChromeOS!
