With public key authentication, the authenticating entity has a public key and a private key. If the private key is not secured, anyone who obtains the private key can impersonate the account. Enter passphrase empty for no passphrase : It's up to you whether you want to use a passphrase. Due to internal limitations, this must be unique across all user accounts; if you want to specify one key for multiple users, you must use a different comment for each instance. I feel this is best done as a one-off, rather than in your regular manifests, or you risk after a few years go by having a very lengthy list of deleted resources that would never actually be present anymore, anyway. The hard way, but possibly more secure, would be to run our openssh keygen process above on every machine for every user and add the public key to hiera. The public key itself; generally a long string of hex characters.
To change the passphrase, click on Load to load an existing key, then enter a new passphrase, and click Save private key to save the private key with the new passphrase. This is the basis we will use to generate our file. All other use is unauthorized. Update : I have since published a forge module that can be used to distribute keys as well. Is there an easy way of doing this? If you are a Puppet expert, please feel free to weigh in below in the comments. You may be logging into these servers frequently and transfering files between the two. We don't have a Jenkins user on the development box.
This accepts the default file location. You may not want all your ssh private keys stored in one place, for instance. It's never transmitted over the Internet, and the strength of your key has nothing to do with the strength of your passphrase. I did some research and found , but I couldn't get it working. Transfer Client Key to Host The key you need to transfer to the host is the public one. They should have a proper termination process so that keys are removed when no longer needed.
The algorithm is selected using the -t option and key size using the -b option. The passphrase is used for encrypting the key, so that it cannot be used even if someone obtains the private key file. The basic property that the resource should be in. If your goal is to be able to rebuild the same machine over and over or if you want several load balanced instances then you would probably want the same key, not a new one. In the worst case, they could be used to. The file in which to store the ssh key.
Puppet can manage network and windows devices, and what happens if you apply the same resource there? Generating a key pair provides you with two long string of characters: a public and a private key. Then boot the system, collect some more randomness during the boot, mix in the saved randomness from the seed file, and only then generate the host keys. Puppet can make it quicker and easier to manage user accounts securely across a large network. Running puppet against this environment should show all our specified changes and we can check the file it generates:. This addresses how to distribute keys to node from the fileserver, but I wonder if there is a mechanism where if the key doesn't exist on the fileserver, the key that currently exists on the node is pulled in and saved for future reference - i. This is where I put sensitive node data like ssh host keys. That would add it everywhere, or at least try to.
They may just not have the mechanical randomness from disk drive mechanical movement timings, user-caused interrupts, or network traffic. If you merge this into production, then all nodes should shortly have this key. This is where puppetdb comes into play. Multiple values must be specified as an array. Has anyone found a guide on how to set this all up how to generate keys, where to put them etc.
Now you can go ahead and log into your user profile and you will not be prompted for a password. Creating Host Keys The tool is also used for creating host authentication keys. You can get debugging information from both the client and server. Edit: I created a module 'ssh'. GjjQfJ7', } } Run Puppet: root puppet-agent:~ puppet agent --test Info: Retrieving plugin Info: Caching catalog for puppet-agent. Server listening on :: port 22. There are a few things which could prevent this from working as easily as demonstrated above.
Our guide specifies three items, an shosts. Valid values are ssh-dss also called dsa , ssh-ed25519 also called ed25519 , ssh-rsa also called rsa , ecdsa-sha2-nistp256, ecdsa-sha2-nistp384, ecdsa-sha2-nistp521. The question is: How does one create the certificates? For detailed installation instructions, see. To securely communicate using key-based authentication, one needs to create a key pair, securely store the private key on the computer one wants to log in from, and store the public key on the computer one wants to log in to. If you are using keys with local users, I highly recommend using the forge module.
Would you want to apply the resource there? Do I set up a Jenkins cert and put part of it on the deployment box, or set up a cert on the deployment box, and put part of it on Jenkins? Note that if you protect your key with a passphrase, then when you type the passphrase to unlock it, your local computer will generally leave the key unlocked for a time. The private key is kept on the computer you log in from, while the public key is stored on the. Issue the following commands to fix: ssh-add This command should be entered after you have copied your public key to the host computer. I hope this helps make navigation in your network a bit easier. The authentication keys, called , are created using the keygen program.
