Github SSH Key Not Working For Command Line : Troubleshooting

Github SSH Key not working for command line but is working for Mac GUI Tool from Github – this is quite common situation and here is very easy way to fix it. Github has official guide for Github SSH Key not working for command line, but actually that is not very practical in all cases. They have used an one user, one repository (that is Github) specific guide.

 

Github SSH Key not working for command line : Why it Happens

 

Github SSH Key not working for command line but nicely for command line tool, happens due to actually wrong setup of the Github App or may be they deliberately created the App in an way to avoid UNIX’s security which actually will create the installation difficult or may be they thought that who will use command line tool will not use the GUI tool.

It happens when there are lot of other repositories on various servers already added before adding the SSH keys of Github on your OS X or may be that GUI tool. Actually there is not much meaning to dissect the origin problem from so much depth. Understand one thing, that normally OS X will allow id_rsa SSH key but the GUI tool uses the named key. You can manually add that key in Github Interface for CLI or you can use symlink or add another key. We will use the last way.

Github SSH Key Not Working For Command Line : Troubleshooting

 

We are taking that you have some idea how to add, manage SSH keys. Notice the screenshot :

Situation :

When you are running this command :

ssh -vT git@github.com

You are getting this :

debug1: No more authentication methods to try.Permission denied (publickey).
Run this command :

eval <code>ssh-agent

It should return an Agent PID. If it does not work, there is definite gross issue and work from the beginning to generate RSA Key in proper hierarchy for better management. Now Add the Key :

ssh-add ~/.ssh/id_rsa

It will give the return :

Now go back to what Github actually said in the guide (copy paste the url) :

 

 

That is, running :

 

 

Run the command :

 

 

It will copy the big key in clipboard. Your work is to go to the Github’s webcontrol panel and adding another new key. Ultimately you will get two set of keys :

 

 

Obviously you have to paste the clip board in that field to add key by hitting command + V from keyboard. The reason to add two separate keys is for finer independent control and specific tracking.
