Remote server access is essential for QA work in non-local environments:

# Connect to a remote server
ssh qa@staging-server.example.com

# Run a command on a remote server without interactive session
ssh qa@staging-server.example.com "ps aux | grep node"

# Copy test results from remote to local
scp qa@staging-server.example.com:/var/log/test-results.xml ./

# Copy file from local to remote
scp test-data.json qa@staging-server.example.com:/tmp/

# SSH tunnel: Access a remote database locally
ssh -L 5432:localhost:5432 qa@staging-server.example.com
# Now connect to localhost:5432 to reach the remote Postgres
