Creating a new ssh key pair for no-password access to a remote system

wow I just had serious issues with basic ssh usage, so i'll put a summary on the wiki basically most misunderstandings stem from describing these two: client: machine that is trying to ssh into the server server: machine that the client user wants to get to most poor sots are just sitting on the client and they create a pair and push their public key to the server but in my case, more often, i want to create a pair on the server and push the private key to the multiple places i need to connect FROM when doing that, you have to push the public key into the server's authorized_keys and configure the client to juggle multiple private keys create a key pair: ssh suser@server ssh-keygen use defaults will create: .ssh/id_rsa (private key) .ssh/id_rsa.pub (public key) put the public key in place: cd .ssh cat id_rsa.pub >>authorized_keys put the private key on the client and configure: scp id_rsa cuser@client:.ssh/id_rsa_server ssh cuser@client em .ssh/config Host tdm thedigitalmachine.com Hostname thedigitalmachine.com IdentityFile ~/.ssh/id_rsa User m Host server Hostname server.com IdentityFile ~/.ssh/id_rsa_server User suser all is full of light
