无法通过ssh连接到github； 权限被拒绝（公钥）

Question

I'm trying to logon to github via ssh but it fails. I've checked the github troubleshooting page to no avail. I've followed the guide on how to connect via ssh step by step on two separate computers. I've tried specifying the path to id_rsa but it gives the same response. The output I receive is the following:

On the other computer which is a mac it also said key_load_public:No such file or directory after each identity file check. So perhaps ssh is not completely set up on my computers. What is the problem?

Simply follow those steps and you will set up your ssh key in no time:

• Generate a new ssh key (or skip this step if you already have a key)
  ssh-keygen -t rsa -C "your@email"

• Once you have your key set in home/.ssh directory (or Users/<your user>.ssh under windows), open it and copy the content

In order to be on the safe side add the new keys to your ssh agent.

ssh-add ~/.ssh/id_rsa
