SSH Key generation

To generate SSH key for Van Gogh access, do

ssh-keygen 

This will generate a pair of private/public ssh keys that your program will use to access a remote resource. To generate an account, the system administrator will require the public part of the key, while the private stays with you. The public key is stored in .ssh/id_rsa.pub, please attach its content to an email and send it to the administrator. The content is a single line starting with ssh-rsa, a long string of random symbols and a name of the key, typically a username and the name of the PC.

# cat ~/.ssh/id_rsa.pub
ssh-rsa
