Evaluating data analysis challenges in the 3G detector era and discussing the solutions
Setting up an account at INFN CNAF
In order to use Virgo computing resources one needs to request an account.
Connecting via SSH and SFTP
Connections to Virgo computing clusters go through the bastion server. To avoid typing password every time, I recommend setting up ssh keys, as described
ssh ui01, after adding the following lines to the file ~/.ssh/config:
Host bastion Hostname bastion.cnaf.infn.it User bgoncharov IdentityFile ~/.ssh/private_key_file # Tunnel Host ui01 Hostname ui01-virgo User bgoncharov IdentityFile ~/.ssh/private_key_file Proxyjump bastion
Don't forget to replace bgoncharov with your actual username. The above creates an ssh tunnel that is equivalent to the following two commands:
To set up the SFTP connection to the computing cluster ui01-virgo, one needs to:
- Open an ssh tunnel:
ssh [email protected] -L 2000:ui01-virgo:22 -N
- Connect via an FTP manager, i.e. FileZilla, or via a terminal:
sftp -P 2000 [email protected]
I would like to acknowledge the help of Francesca Badaracco with figuring this out.
