Configuring

You may notice that packages in TheorieMPQ are private and that you must be authenticated to download them.

To avoid having to type in the password everytime you install a package or you update them, follow the following instructions.

Generating a ssh key and adding it to GitHub

First we need to generate an ssh key if you don't have one yet. Copy and paste this command in your terminal.

if test -f "~/.ssh/id_rsa"; then echo "Key alread exists. Do nothing."; else ssh-keygen -f ~/.ssh/id_rsa -q -N; fi

Now you surely have an ssh key in ~/.ssh/id_rsa, and we must upload it to github. To do that, you can follow this guide or the instructions below.

copy the content of the file ~/.ssh/id_rsa.pub. To do so, run the command and copy all the output

clear && cat ~/.ssh/id_rsa.pub

To enable automatic logging you should add a few lines to your .ssh/config file. To do so, run the command

nano ~/.ssh/config

and paste the following lines

Host github.com
   HostName github.com
   User git
   IdentityFile ~/.ssh/id_rsa

You're done! To check that everything worked you can run

ssh github.com

and you should see the following output

Hi YOURUSERNAME! You've successfully authenticated, but GitHub does not provide shell access.
Connection to github.com closed.

From now on, when you add private packages to Julia, if they are of the form

] add git@github.com:TheorieMPQ/CornerSpaceRenorm.jl.git

you will not be asked for a password.
