Here is the simplest solution ssh-keygen -R <host> For example, ssh-keygen -R 192.168.3.10 From ssh-keygen man page: -R hostname Removes all keys belonging to hostname from a known_hosts file. This option is useful to delete hashed hosts (see the -H option above).
The problem is having wrong mod on the file. Easily solved by executing – chmod 400 mykey.pem Taken from AWS instructions – Your key file must not be publicly viewable for SSH to work. Use this command if needed: chmod 400 mykey.pem 400 protects it by making it read only and only for the owner.
If the user has not generated a ssh public/private key pair set before This info is working on theChaw but can be applied to all other git repositories which support SSH pubkey authentications. (See [gitolite][1], gitlab or github for example.) First start by setting up your own public/private key pair set. This can use either … Read more
Run the following command to retrieve the SHA256 fingerprint of your SSH key (-l means “list” instead of create a new key, -f means “filename”): $ ssh-keygen -lf /path/to/ssh/key So for example, on my machine the command I ran was (using RSA public key): $ ssh-keygen -lf ~/.ssh/id_rsa.pub 2048 00:11:22:33:44:55:66:77:88:99:aa:bb:cc:dd:ee:ff /Users/username/.ssh/id_rsa.pub (RSA) To get the … Read more
From my .ssh/config: Host myshortname realname.example.com HostName realname.example.com IdentityFile ~/.ssh/realname_rsa # private key for realname User remoteusername Host myother realname2.example.org HostName realname2.example.org IdentityFile ~/.ssh/realname2_rsa # different private key for realname2 User remoteusername Then you can use the following to connect: ssh myshortname ssh myother And so on.
If Machine A is a Windows box, you can use Plink (part of PuTTY) with the -m parameter, and it will execute the local script on the remote server. plink root@MachineB -m local_script.sh If Machine A is a Unix-based system, you can use: ssh root@MachineB ‘bash -s’ < local_script.sh You shouldn’t have to copy the … Read more
Short answer: $ ssh-keygen -p This will then prompt you to enter the keyfile location, the old passphrase, and the new passphrase (which can be left blank to have no passphrase). If you would like to do it all on one line without prompts do: $ ssh-keygen -p [-P old_passphrase] [-N new_passphrase] [-f keyfile] Important: … Read more
None of these solutions worked for me. Instead, I elaborate on @Martin v. Löwis ‘s mention of setting a config file for SSH. SSH will look for the user’s ~/.ssh/config file. I have mine setup as: Host gitserv Hostname remote.server.com IdentityFile ~/.ssh/id_rsa.github IdentitiesOnly yes # see NOTES below And I add a remote git repository: … Read more
Did You Start ssh-agent? You might need to start ssh-agent before you run the ssh-add command: eval `ssh-agent -s` ssh-add Note that this will start the agent for msysgit Bash on Windows. If you’re using a different shell or operating system, you might need to use a variant of the command, such as those listed … Read more
The keys need to be read-writable only by you: chmod 600 ~/.ssh/id_rsa Alternatively, the keys can be only readable by you (this also blocks your write access): chmod 400 ~/.ssh/id_rsa 600 appears to be better in most cases, because you don’t need to change file permissions later to edit it. (See the comments for more … Read more
