ssh/.config

config

Host github.com
        User git
        Hostname github.com
        PreferredAuthentications publickey
        IdentityFile /home/user/.ssh/id_rsa

So the same key is used for all my repositories? I think it is not possible.

How can specify a key for a repository?

Thanks.

thanks boss

thanks guys

It helped alot 🎉

Thank you so much!!

This is helpful, I remember using it for my ~/.ssh/config

Note that the same rule is also required for gist.github.com.
You might be able to write a single rule for both github.com and gist.github.com.

Thanks !

It just does not work.

git@github.com: Permission denied (publickey).

@sylin257 Maybe also check these:

• that your public key is uploaded to https://github.com/settings/keys
• that the private key refered to in ~/.ssh/config matches the public key you've uploaded to github
• that you have push rights to the repository you want to push to
• git remote -v while in the repository, to see if the remote is correct

Amazing! Thanks a lot! It works.

Maybe searching has already showed you this but since this discussion is #3 for me when I search 'ssh github config' I felt reacting to the somewhat older comment might be usefull to others as well.

It is possible to have a ssh key bound to a repository. This is a newer command that has to be run in a repo dir to set it's ssh.

Default:

git config core.sshCommand "ssh -i ~/.ssh/id_rsa_file"

I forgot the exact reason but some people suggest redirecting the output

Alternate:

git config core.sshCommand "ssh -i ~/.ssh/id_rsa_file -F /dev/null"

@P-Louw thank you! :)

I add StrictHostKeyChecking no just for github.com. to avoid the messages like Warning: Permanently added the RSA host key for IP address '140.82.113.3' to the list of known hosts., as GitHub has many servers that get added to known_hosts.

Do NOT do this, I've never experienced this warning with github as they use a single hostkey as they should. If you get this warning after the connection it is a sign that you're connection is or was intercepted.

@hunterjackson You must be using an RSA key. I was using a ECDSA key and now a Ed25519 key. From my understanding these types of keys have only recently had a single hostkey for all servers.

@franmadj I write a naive tool about it. see https://github.com/alingse/git-ssh-key
just run

pip install git-ssh-key
#  this will change repo link to an alias link
git-ssh-key https://github.com/alingse/git-ssh-key.git

Host github.com-repo-0
        Hostname github.com
        IdentityFile=/home/user/.ssh/repo-0_deploy_key

Host github.com-repo-1
        Hostname github.com
        IdentityFile=/home/user/.ssh/repo-1_deploy_key

Thanks a lot ! after 7 hours trying to clone my repository finally found the solution

Thnx

FYI: I landed here after the config on this GitHub help page didn't work (maybe its the wildcard or that you need a HostName field as well?). I also added the following to avoid having to enter my password every time:

   UseKeychain yes
   AddKeysToAgent yes

I also added the following to avoid having to enter my password every time:

   UseKeychain yes
   AddKeysToAgent yes

Just note that UseKeychain yes is Mac only, AddKeysToAgent works on Linux.

I also use the following, this will tell SSH to not try every identity file within that folder, but only the one’s defined.

    IdentitiesOnly yes

On windows, using the following config file... I'm still prompted for the passphrase each time :( Any ideas?

Host github.com
  HostName github.com
  User cefect
  IdentityFile ~/.ssh/is_ed
  AddKeysToAgent yes
  IdentitiesOnly yes
  #UseKeychain yes  #mac only

@cefect
Maybe check if you have an SSH agent working and running.
Also check if your ssh key is loaded in the agent ssh-add -L

@cefect Check if you have added a SSH key on GitHub website under your profile. https://github.com/settings/keys. If so, make sure you are using the SSH URL when making the connection to origin. Should be git@github.com instead of https://github.com

Thanks @wsdookadr, keys are added:
\

Thanks @LarsPeterson,
key added to profile:

not sure what you mean by 'using the SSH URL when making the connection to origin', maybe this?

note I'm only trying to get rid of the key passphrase prompt (the ssh keys are working in that I don't have to enter username and password each time... just passphrase)

@cefect

Oh whoops just read your comment again. You need to generate a new key and skip the passphrase part. Just don't enter anything. Then go through the whole process again, add to profile, etc.

thanks for that!

This sort of configuration appears to be required if you want to use PHPStorm to clone from VCS via WSL.

 ssh-add {rsa_file} 

It works.

@rohitchormale, you're genius!!!

@rohitchormale thank you!
