ssh tunnel creation connection timed out / service not found

[dhruvikhankhoje]

After running ec2.sh, I ran the ec2_create_tunnel.sh command, and got this result:

$ ./ec2_create_tunnel.sh

This script will create an ssh tunnel between the ec2 host's port 5000 and your local port 5000. This will enable you to view web applications you run from ex. Agile_Data_Code_2/ch08/web to be viewed at http://localhost:5000 Note: the tunnel will run in the background, and will die when you terminate the EC2 instance.

First we will forward the port the web appliations use... Forwarding the remote machine's port 5000 to the local port 5000, which you can then access at http://localhost:5000 Executing: ssh -N -i ./agile_data_science.pem -o StrictHostKeyChecking=no -L 5000:localhost:5000 ubuntu@$EC2_HOSTNAME &

Next we will forward the port the Jupyter Notebooks use... Forwarding the remote machine's port 8888 to the local port 8888, which you can then access at http://localhost:8888 Executing: ssh -N -i ./agile_data_science.pem -o StrictHostKeyChecking=no -L 8888:localhost:8888 ubuntu@$EC2_HOSTNAME &

Next we will forward the port that Airflow uses... Forwarding the remote machine's port 8080 to the local port 8080, which you can then access at http://localhost:8080 Executing: ssh -N -i ./agile_data_science.pem -o StrictHostKeyChecking=no -L 8080:localhost:8080 ubuntu@$EC2_HOSTNAME &

On doing the same process again, I got this output: $ ./ec2_create_tunnel.sh ./ec2_create_tunnel.sh: line 4: [: too many arguments
