Setup Environment (macOS / Linux)
Important Note: These setup configuration steps will only function successfully after your official cluster access application has been approved.
Step 1: Verify or Create Local SSH Directory
ls -ld ~/.ssh
# If directory is not present, generate it:
mkdir ~/.ssh
# If directory is not present, generate it:
mkdir ~/.ssh
Step 2: Create Private Authorization Key File
Navigate to your local configuration space and create your key file (you may choose any name alternative to your_cayuga_key):
cd ~/.ssh
nano your_cayuga_key
nano your_cayuga_key
Paste your target private authentication credentials directly into this interface, then save and exit.
Step 3: Restrict File System Permissions
chmod 600 ~/.ssh/your_cayuga_key
ls -l ~/.ssh
ls -l ~/.ssh
Warning: Remote host handshakes will fail automatically if system security parameters are broad or insecure.
Step 4: Execute Remote Core Connection
ssh -i ~/.ssh/your_cayuga_key <your_cwid>@cayuga-login1.cac.cornell.edu
