Study Notes

Connecting to Matrix

To connect to matrix, you must be "On Campus" or connected to SenecaNet
Web access is allowed, but not command line login
From off campus, connect to Seneca VPN for access to matrix
SSH (Secure Shell) is used to connect to matrix securely

Common Issues

Problems can occur due to:
- Mis-spelled matrix username or password
- CAPS LOCK on by mistake
- Incorrectly typed password
- Incorrectly typed matrix username

Using PuTTY

Download PuTTY for Windows and run the installer
Run the PuTTY command and use the settings:
- Host Name: matrix.senecapolytechnic.ca
- Port: 22
- Connection Type: SSH
A terminal window should pop up, asking for login credentials

Connecting to Matrix from MacOS/Linux

Open Terminal on MacOS/Linux and use the command:
- ssh [email protected]
Replace senecausername with your actual username

Remember to Log Out

When finished on matrix, remember to log out using the exit or logout commands
Use ctrl-D to exit (means "end of file")
Log out to help ensure you haven't left anything running

Simple Commands to Start With

Linux Command Prompt: contains useful information in a terse format
Windows CMD Default Command Prompt: indicates the current directory

Hierarchical File Systems

Both Linux and Windows use hierarchical file systems
Files are organized in folders and subfolders
In Linux, the topmost directory is the root (/)
In Windows, the hierarchy starts from drives (e.g., C:, D:)
