| hterm and Secure Shell |
| Additional information for |
| Chrom(e|ium) OS 'crosh' Users |
| |
| April 25, 2012 |
| |
| |
| This document explains in a little more detail how hterm relates to and |
| interacts with the "crosh" command on Chrome OS and Chromium OS. |
| |
| From here on, this document will only mention Chrome OS. You can assume |
| that it applies to Chromium OS as well. |
| |
| |
| 1. The "crosh" shell |
| |
| Chrome OS comes with a small set of command line commands accessible from |
| the "crosh" shell. You can open a new crosh instance with the Ctrl-Alt-T |
| key sequence. |
| |
| The crosh commands are intended to be used for troubleshooting Chrome OS. |
| Because it is not intended for frequent use, the crosh shell does not have |
| an associated icon in the app launcher. The only way to get to it is via |
| the Ctrl-Alt-T sequence. |
| |
| You do not need to install any additional applications to access crosh. |
| This is critical for debugging network connectivity issues. It also means |
| we can avoid a "go install this tool" step from diagnostic procedures. |
| |
| The crosh shell happens to include an "ssh" command. Many people use this |
| on a daily basis for reasons other than Chrome OS diagnosis. This was a |
| stop-gap solution that worked well for a while. However, the crosh ssh |
| command is no longer recommended for use as a daily ssh client. You should |
| migrate to the new "Secure Shell" application instead. |
| |
| |
| 2. The "Secure Shell" application. |
| |
| The Secure Shell application is a dedicated ssh client that works on Chrome |
| OS as well as Chrome on other platforms. |
| |
| Unlike the crosh shell, the Secure Shell application does NOT ship with |
| Chrome OS. You've got to manually install it from the Chrome Web Store |
| from this link: |
| |
| https://chrome.google.com/webstore/detail/pnhechapfaindjhompbnflcldabbghjo |
| |
| Once installed you should see a new "Secure Shell" icon in your application |
| launcher. |
| |
| You can get to crosh from Secure Shell by typing "crosh" when prompted for a |
| destination. (This won't work on non-Chrome OS systems, of course.) |
| |
| If Chrome OS notices that you have installed Secure Shell, it'll launch that |
| instead of the built-in crosh command. This allows you to upgrade the |
| terminal emulator portion of the crosh shell without waiting for the next |
| Chrome OS release. |
| |
| If you would like to revert to the built-in crosh terminal emulator, |
| uninstall or disable the Secure Shell application. |
