Your identification has been saved in /home/training/.ssh/id_rsa. The minimum effort to generate a key pair involves running the ssh-keygen command, and choosing the defaults at all the prompts: $ ssh-keygenĮnter file in which to save the key (/home/training/.ssh/id_rsa):Įnter passphrase (empty for no passphrase): Generating your key pair and propagating your public key is simpler than it sounds. Generating a key pair and propagating the public key A local caching program such as ssh-agent or gnome-keyring allows you to enter that passphrase periodically, instead of each time you use the key to access a remote system. Your private key may be secured locally with a passphrase. The private key remains secure on your own workstation, and the public key gets placed in a specific location on each remote system that you access.

#Copy key ssh password#

Instead of the remote system prompting for a password with each connection, authentication can be automatically negotiated using a public and private key pair.

with your SSH key.If you interact regularly with SSH commands and remote hosts, you may find that using a key pair instead of passwords can be convenient. As long as you remembered to set permissions, it should work, and you should be able to use git/hg/etc. This opens your local SSH agent, and allows you to add keys that can be picked up by other programs, such as source control.įinally, run ssh-add ~/.ssh/. Now, at a terminal, run eval $(ssh-agent).

Unfortunately it doesn't directly tell you how to fix the problems, but 400 permissions, which mean 'readable to me, not available to anyone else', will correct the problem. This is necessary because the default permissions (when copied from Windows) will be 770 the SSH utility will tell you that is too permissive and that it will ignore the key. If you copied the key file from Windows, now open a terminal to the ~/.ssh folder, and run chmod 400. ssh directory, you need to chmod 0700 ~/.ssh so that the ssh tool believes that the directory is really private to you. You may need to create this folder if you haven't used SSH on your Linux box before. for use with source control systems?Ĭopy it to your ~/.ssh folder on Linux. If you are using it for SSH directly, you can use it as Adonis mentioned. Using the OpenSSH key on Ubuntu (or derivatives) To do this, open PuttyGen, Load the private key, and then go to the 'Conversions' menu and choose 'Export OpenSSH Key'

Since I don't have enough reputation to comment, I'll add the detail via this answer. The answers/comments by Adonis and Thomas are basically correct, but lack some detail that I needed to get this working in practice. The output while trying with ssh -i ~/.ssh/private_key.ppk key '~/.ssh/private_key.ppk': invalid format Permission denied (publickey). Is there any way to use these keys on Ubuntu? Maybe through openssh? So, as the first error suggest, after convert the private key to openssh PEM format through PuTTYgen and then load that file to SSH/Auth, the 'No supported' message remains before: Unable to use key file '~/private_key_openssh' (OpenSSH SSH-2 private key (old PEM format) ).

Then I tried to copy those files in my ubuntu machine (21.04), and logged in loading the private key (open putty, write the and then load the private key at SSH>Auth), but there is unable to connect being rejected by the server as this error says: Unable to load key file '~/private_key.ppk' (PuTTY key format too new).Īnd an emerging windows appears saying: No supported authentication methods available (server sent: publickey)

#Copy key ssh software#

Using this software on windows I can connect to the server as usual. I've generated two keys on PuTTY: public and private.
