There are two workstations "euler" and "fourier", see this page. To connect to them from inside CAM, do
ssh euler ssh fourier
To login from outside CAM, please ask me for details. When you connect from outside CAM, display may not work, you have to do all work from the terminal.
On euler or fourier, check your $HOME/.bashrc
file. It runs a script in my directory to set some paths to various softwares. You can examine this file using vi/vim
vi /home/praveen/.setenv
Everything you need should be installed already. If something is missing, tell me about it.
YOU SHOULD SETUP SSH KEYS so you can login without typing password everytime. On your laptop/desktop, run the following ONCE
ssh-keygen
Then just enter for all questions. This creates a directory $HOME/.ssh
which contains some files. The file $HOME/.ssh/id_rsa.pub
is your public key which must be copied to the remote server. You can do this manually by logging into the remote server and copy the contents of $HOME/.ssh/id_rsa.pub
from your local computer to $HOME/.ssh/authorized_keys
on the remote computer. Alternately, you can use ssh-copy-id command.
From your local computer, do
ssh-copy-id USERNAME@REMOTEHOST
where USERNAME is your username on the REMOTEHOST. Enter password for your REMOTEHOST to copy the ssh id.
From your local computer, do
ssh-copy-id -p PORT USERNAME@158.144.181.10
"PORT" depends on which computer you are connecting to, euler, fourier, etc. USERNAME is your username on the remote computer, euler, fourier, etc.
Copy the contents of your $HOME/.ssh/id_rsa.pub
file into your github or bitbucket account by logging in through your browser. This option should be available somewhere in the settings part of your github/bitbucket account. Once keys are setup, you can clone and do push/pull without entering your github/bitbucket password everytime. E.g., clone using git
git clone git@github.com:USERNAME/PROJECT.git
Here USERNAME is your github username and PROJECT is the name of the git repository you want to clone.
Edit the file
sudo vi /etc/ssh/sshd_configand add these lines
ChallengeResponseAuthentication no PasswordAuthentication no UsePAM no PermitRootLogin no PermitEmptyPasswords noRestart sshd
sudo systemctl reload sshdCheck that password based login is not allowed
ssh HOSTNAME -o PubkeyAuthentication=nowhich should say permission denied.
