Following this post to fix the following error:

Through the post made sure that I have a key and SSH is using it. I have even verified that the public key is attached to my github account. Not sure of the -1 in the last 3 lines? Saw all the related posts but no help.

Answer 1

I was doing ssh -T git@github.com . I had to do ssh -T git@github.company's-github-account-name.com . All set now.

Answer 2

The most likely problem, it seems, is that the public key isn't actually correctly attached to your github account. Can you confirm that the output of

ssh-keygen -y -f /Users/user/.ssh/id_rsa

is exactly the same as what you put in Github, and that if you do

ssh-keygen -y -f /Users/user/.ssh/id_rsa > tmp
ssh-keygen -l -f tmp

..that the fingerprint shown matches exactly one of the fingerprints shown at https://github.com/settings/ssh ?

Edit : you confirmed. It looks like you've done everything right, then. I can't think of much more that could be going wrong. I suppose you might be getting the wrong remote host (the IP is right, but a malicious person or a misbehaving corporate firewall could still be sending the packets to the wrong place). You can check this by seeing what fingerprint you've stored in your known_hosts file:

ssh-keygen -F github.com > tmp
ssh-keygen -l -f tmp

The output should start with:

2048 16:27:ac:a5:76:28:2d:36:63:1b:56:4d:eb:df:a6:48

If it does, then I suppose it might be a problem on the github side after all. Maybe they have some sort of delay in between receiving your public key and propagating it to the main ssh server. You probably ought to try the "contact a human" link at the bottom of the page you cited.

Extensive troubleshooting of this GIT issue “Git – Permission denied (publickey)” can be done with the below command:

ssh -vT git@github.com

1. Navigate to .ssh directory inside your home directory

    cd ~/.ssh 

2. Generate the public/private rsa key pair

    ssh-keygen 

3. Copy the SSH key to the clipboard using the below command

    cat id_rsa.pub | clip 

4. Navigate to your GIT repository in https://github.com/

5. Go to Account Settings –> SSH Keys

6. Click on Add SSH key and store the key

Answer 4

I agree with the answer posted by @Ava. Using ssh -T git@github."company's_github_account".com It worked for me. Many times, we do not realize that a simple fix exists for seemingly complex problems.
