SSH to HPC without password¶
Make sure you are connected to $ecureNet
For non-Windows users¶
Open a terminal and do the following 4 steps.
Step 1. Create public/private RSA keys.
ssh-keygen -t rsa -N "" -f ~/.ssh/id_rsa
You should be able to see an output like below:
The key's randomart image is:
+---[RSA 2048]----+
| =+. o o .|
| . o o. @ o.=|
|. . += . * + =o|
|. ..+oo. . o . .|
|. + ++S o = |
| . . *.. B o |
| . . o . =E |
| . o... |
| . o. |
+----[SHA256]-----+
Step 2. Create a folder on HPC. (Enter your HPC password).
ssh hpc mkdir -p .ssh
Step 3. Let HPC knows that it is you. (Enter your password for the last time).
cat ~/.ssh/id_rsa.pub | ssh hpc 'cat >> .ssh/authorized_keys'
Step 4. Enjoy logging in without password
ssh hpc
