Setting up an account at INFN CNAF
In order to use Virgo computing resources one needs to request an account here.
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 here. The easiest way to connect is with one command, i.e., 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:
ssh [email protected]
ssh bgoncharov@ui01-virgo
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 bgoncharov@localhost
I would like to acknowledge the help of Francesca Badaracco with figuring this out.
