| **More advanced:** To make life easier and avoid typing passwords all the time when contacting the remote (i.e. github), follow the recipe here: https://help.github.com/articles/generating-ssh-keys/. If you are still asked for passwords about your id_rsa.pub file, it is the password to log in to the machine where that file is stored which is needed (or the password you gave when you created the id_rsa.pub-file). Using this procedure, you can clone with <file> git clone git@github.com:metno/noresm.git </file> | **Also do the following on all machines where you use git:** |
| | * **Make sure you have a version of git >= 2.0** (add the line "module load git" to your .bashrc files on hexagon, vilje) |
