できないこと

GitHubに対してSSH接続できない

やったこと

ssh-keygenでKey作成
/Users/xxxxxx/.ssh(xxxxxx部分はユーザ名)配下に
以下2ファイルができることを確認
1. id_rsa
2. id_rsa.pub
作成したpubkey(id_rsa.pub)をGitHubに登録
pbcopy < ~/.ssh/id_rsa.pubでクリップボードにコピーした内容をそのまま貼り付け/設定
接続確認
- 通常
  ssh -T github.com
- デバッグ
  ssh -vT github.com

結果

Permission denied (publickey).とエラーが出て接続できない
