The great feature HostKeyAlias solves your problem: ssh -o HostKeyAlias=hostkeyalias__vm_2013-05-11_07 user@host creates an entry hostkeyalias__vm_2013-05-11_07 (without IP) in known_hosts. Of course, you could write a script or shell function which sets this value before each ssh call. Or you use a shell variable: HOSTKEYALIAS=hostkeyalias__vm_2013-05-11_07 ssh -o HostKeyAlias=$HOSTKEYALIAS user@host and change $HOSTKEYALIAS whenever the VM is … Read more
Note that there are at least two bug reports for ssh-add -d/-D not removing keys: “Debian Bug report #472477: ssh-add -D does not remove SSH key from gnome-keyring-daemon memory“ “Ubuntu: ssh-add -D deleting all identities does not work. Also, why are all identities auto-added?“ The exact issue is: ssh-add -d/-D deletes only manually added keys … Read more
ssh-keygen -y -f myfile-privkey.pem If the key is password protected, you will see a “password:” prompt. The flags in this command are: -y Read private key file and print public key. -f Filename of the key file. As extra guidance, always check the command someone, especially online, is telling you to use when dealing with … Read more
Here’s another hack using plain bash without temporary files: while read l; do [[ -n $l && ${l###} = $l ]] && ssh-keygen -l -f /dev/stdin <<<$l; done < .ssh/authorized_keys You can easily make it a function in your .bashrc: function fingerprints() { local file=”${1:-$HOME/.ssh/authorized_keys}” while read l; do [[ -n $l && ${l###} = … Read more
You can try adding this: eval $(ssh-agent -s) ssh-add ~/.ssh/id_rsa This way the ssh-agent does not start a new shell, it just launches itself in the background and spits out the shell commands to set the appropriate environment variables. As said in the comment, maybe you do not want to run the agent at all … Read more
According to this, this command can be used: ssh-keygen -f id_rsa -e -m pem This will convert your public key to an OpenSSL compatible format. Your private key is already in PEM format and can be used as is (as Michael Hampton stated). Double check if AWS isn’t asking for a (X.509) certificate in PEM … Read more
This field is a comment, and can be changed or ignored at will. It is set to user@host by default by ssh-keygen. The OpenSSH sshd(8) man page describes the format of a public key thus: Public keys consist of the following space-separated fields: options, keytype, base64-encoded key, comment. . . . The comment field is … Read more
To change the passphrase on your default key: $ ssh-keygen -p If you need to specify a key, pass the -f option: $ ssh-keygen -p -f ~/.ssh/id_dsa then provide your old and new passphrase (twice) at the prompts. (Use ~/.ssh/id_rsa if you have an RSA key.) More details from man ssh-keygen: […] SYNOPSIS ssh-keygen [-q] … Read more
