Performing a Re-Install WITHOUT a Backup
If you want to retain your node number then this will be a bit more tricky in that you have to have a backup in order to have the “PGP Keys” that were generated at the time the original node number was assigned. So the IRLP Installs team will need to be directly involved.
Install the operating system using the most recently available file. You can download this from http://mirror.irlp.net/iso/
and create your installation media with the fresh .iso
Then you will need to email installs@ irlp.net with your name, node number (that you want recovered), SSH username & password and your publicly accessible IP address. Google: “What is my IP?” and Google will tell you your IP.
