Overview

As an internal NRC employee, you can access the AI for Design (Trixie) Cluster using your SRN credentials. On your first login, you may be required to change your password.
Please note: during the password change, the first prompt asks for a confirmation of your existing password prior to requesting a new one.

In order to access Trixie, you will need to use an SSH client. Please note that you cannot access Trixie using a web browser. On Mac OSX and Linux, SSH is installed by default. On Windows you will need to install Putty if it is not installed already. You can install Putty from the NRC software portal which should be an icon on your Windows desktop.

Trixie can only be accessed from one of two ways

1. The Secure Research Network (SRN)
2. The Legacy network using the bastion host

The following sections will detail the procedures for logging into Trixie from these networks.

Logging in From the SRN Network

In order to access Trixie from the SRN network, you can login to Trixie directly with an SSH client.

Initialize SSH Connection with Mac OSX / Linux

For Mac OSX and Linux you can open a new terminal and connect to trixie.res.nrc.gc.ca via ssh using your SRN credentials and the following command, where <username> is your SRN user ID consisting of your lastname followed by one or more initials of your first name - like doej for John Doe.

ssh -l <username> trixie.res.nrc.gc.ca

Initialize SSH Connection with Windows

For Windows, you can create a Putty profile to SSH into Trixie. Note that <username> is your SRN user ID consisting of your lastname followed by one or more initials of your first name - like doej for John Doe.

Under Session

1. Set Host Name (or IP address): <username>@trixie.res.nrc.gc.ca
2. Set Port: 22
3. Add a name for Saved Sessions – perhaps Trixie
   
   
4. Click Save

Once the settings have been saved, you can double click on the name in the list of Saved Sessions to open a session to Trixie.

Logging into Trixie - a Tutorial

In the following procedure, the information printed in the images may not be the same as what you will see when you login. However the steps will be the same.

Please perform the following steps to access Trixie.

1. From the terminal prompt, use SSH to log into trixie.res.nrc.gc.ca with your SRN account and password with a similar command as the following.
   ssh <username>@trixie.res.nrc.gc.ca
2. If a message similar to the one below appears, then simply type in yes to the prompt as shown below
   
3. Once you have successfully logged in, you will be logged into Trixie – your screen should look similar to the following
   

NOTE 1: After successful authentication, you should see the Trixie cluster login banner with the terms of use and be placed in a shell in your home directory on the cluster, similar to the image above.

NOTE 2: You will be placed in your home directory which only you have access to. For more information on the cluster and its usage, please see the:

Logging in From the Legacy Network

In order to access Trixie from the Legacy network, you will need to use an SSH client to login to a bastion host with the LoginTC authentication application.

Accessing Trixie with LoginTC 2-Factor Authentication

LoginTC is an authentication application that you should have installed on your mobile phone. It implements a two-factor authentication system for secure access to Trixie.

LoginTC Application Setup

Before you attempt your first login, the following initial installation and configuration of LoginTC must be implemented.

• You should have received an email to setup and initialize the LoginTC application (for iOS, Android, or the Chrome web browser)
• Set up LoginTC using the directions provided to you by email

Initialize SSH Connection with Mac OSX / Linux

For Mac OSX and Linux you can open a new terminal and connect to trixie.nrc-cnrc.gc.ca via ssh using your PUB account and the following command, where <username> is your SRN user ID consisting of your lastname followed by one or more initials of your first name - like doej for John Doe.

ssh -l <username>@pub.nrc-cnrc.gc.ca trixie.nrc-cnrc.gc.ca

TIP 1: Your PUB password is the same password you use to connect to the Legacy VPN.

TIP 2: Some users have reported that using doej did not work for their username. Please try using the first.last format - for example john.doe - for your username if doej doesn't work for you

Initialize SSH Connection with Windows

For Windows, you can create a Putty profile to SSH into the bastion server. Note that <username> is your PUB user ID consisting of your lastname followed by one or more initials of your first name - like doej for John Doe.

TIP: Some users have reported that using doej did not work for their username. Please try using the first.last format - for example john.doe - for your username if doej doesn't work for you

Under Session

1. Set Host Name (or IP address): <username>@pub.nrc-cnrc.gc.ca@trixie.nrc-cnrc.gc.ca
2. Set Port: 22
3. Add a name for Saved Sessions – perhaps Bastion
   
   
4. Click Save

Once the settings have been saved, you can double click on the name in the list of Saved Sessions to open a session to the bastion server.

Changing passwords

Passwords on the PUB and SRN accounts expire after a certain amount of time and must be changed. If you do not change your password, you could be locked out of the system.

Watch for the pop-up message notifying you to change your password, or set yourself a reminder to change your password every so often - perhaps every 90 days.

Being Forced to Change Your Password

If your password has expired, or you are using a password for the first time, then the system will likely force you to change your password. Please note that you will be prompted for your original (or current) password first and then you will be prompted to enter your new password twice.

The following is an example of the system forcing you to change your password

1. During a login session you will be prompted to enter your password and then the system forces you to change your password. You should see a message similar to the one below – remember to enter your original password first and then enter your new password twice.
   
2. The system will automatically log you out, thus, you will need to login again using your new password

Change Your PUB Password

You can change your PUB password by logging into the following website. The site allows you to manage your PUB account. Please use one of the following formats for your username

• john.doe@pub
• doej@pub

PUB Account Management

Please note that the Reset Password feature will not work if you do not fill in the security questions on the website. Therefore it is strongly recommended that you fill in the security questions so that you can reset your password if necessary.

Change Your SRN Password via Linux Terminal

1. Ensure you are logged into the Trixie server (trixie.res.nrc.gc.ca)
2. Type passwd then hit Enter
3. You will be prompted for your original (or current) password first and then you will be prompted to enter your new password twice. You should see a message similar to the one below – remember to enter your original password first and then enter your new password twice.
   
   
4. The system will automatically log you out, thus, you will need to login again using your new password
