Authorized users of Computerome 2.0 may log in using SSH version 2 to the interactive front-end node ssh.computerome.dk.
Computerome 2.0 requires two-factor authentication for access:
- Your user name is sent to you in email.
- For first-factor authentication, use the temporary password sent to you in SMS. Change it at first login using passwd command.
- For second-factor authentication, use:
- either the passcode sent to you in SMS at login attempt (the default option),
- or install the Entrust IdentityGuard Mobile app on your mobile to receive and approve push notifications. This is how you set up the soft token.
In Computerome 2.0, no other software token (e.g Google Authenticator) is available for second factor authentication, than Entrust IdentityGaurd Mobile app.
Please note: lifsci is fictional user for educational purposes. Please replace it with the username sent to you - <username>@ssh.computerome.dk
Windows PC users
Windows PC users are recommended to use the free Windows SSH client PuTTY for command-line SSH login to Computerome. If you need to display graphical tools from Computerome on your Windows PC, PuTTY will forward your X11 (a.k.a. X-Windows) display onto your PC.
However, in order to Windows to actually display X11, you need to install an X11 server on your PC. Please, see the excellent X11 on Windows page on Niflheim Wiki for further information.
Several commercial solutions are also available, some even provide bundled SSH and X11 functionality - such as MobaXterm for instance.
MobaXterm and 2-factor authentication
MobaXterm does not "play nice" with 2-factor authentication.
Per default, MobaXterm will open an embedded SFTP browser (called SSH-browser) when you start the terminal; this does not work with 2-factor authentication, since it means that you will attempt to start two different connections simultaneously, resulting in unwanted behavior in your login.
To avoid this, you need to make the following changes to MobaXterm:
You should always create a new connection in MobaXterm by clicking
Copy and paste problems on Computerome X applications when using Xquartz server on Mac
If you try using ssh-type commands in the MobaXterm terminal window, 2-factor authentication will fail.
SFTP Client Configurations
In order to use most FTP/SFTP clients on a 2 factor system you will need to limit the maximum simultaneous connections to avoid multiple login prompts. You should also set up Entrust as your Two-Factor Authentication method.
Here you can see how to setup the mostly used clients.
Changes has been made in recent versions which means that Quickconnect no longer works with 2 factor authentication
Seems to be a good solution for Windows.
The current Cyberduck version works with our Two-Factor Authentication as long as it is Entrust.
Login access restrictions
Please note that for reasons of security, SSH login access is only possible from the known Internet domains of authorized users.
If your connection terminates unexpectedly
If you are connecting to Computerome though a slightly unstable connection (Internet/WAN/similar), you may experience that it terminates with messages like
In such a case you could try adding the following to your
If you are on Windows, using PuTTY, the equivalent is to set
