Setting up git on Linux server - linux

Question

I am trying to set up a git repo on a server running Linux RedHat.
I follow the instructions on Github's help page. I reach the step where the instructions tell me to ssh into git#github.com.
this gives me the following error -
$ ssh -T git#github.com
Permission denied (publickey).
So then I did $ ssh -vT git#github.com and get this -
OpenSSH_5.3p1, OpenSSL 1.0.0-fips 29 Mar 2010

Here's where I currently am -
$ pwd
/home/min/a/foo/.ssh
I don't understand what's going wrong? Also, if I try to add this path by doing ssh-add, it says "Could not open a connection to your authentication agent".

Answer 1

It appears that you either have not uploaded a key to github, or you have uploaded a key that does not match your default key for the current user.
Check that your local key is on github:
Get your key's fingerprint: ssh-keygen -lf ~/.ssh/id_rsa.pub
Check this against the list of allowed keys on github: https://github.com/settings/ssh
Alternatively, check that your key is enabled on github. A little while ago, a there was an security issue related to ssh keys on github. All ssh keys were disabled in order to force users to review their list of allowed keys. If you've not used github recently, yours could still be disabled.

Answer 2

Just in case someone is interested or has a similar issue and checks this post, the solution is to cd out of the .ssh dir and ssh into github. Provided everything else is followed exactly as on github's help page, this will solve the problem.
