ssh接続でToo many authentication failuresが出る

Posted at

課題

ssh-agentに鍵を追加すると、ログインするときに下記のエラーが表示された。
Received disconnect from local_id: 2: Too many authentication failures for yamaura

原因

ログインしようとした環境はパスワード認証にも関わらず、鍵認証でログインしようとしているため。

解決策

パスワードを使うようにする。

下記のコマンドでログインする。

ssh ip_adress -A -l user_name -o PreferredAuthentications=password

もしくは~/.ssh/config に下記設定を行う。

Host dev
  HostName id_adress
  User user_name
  IdentitiesOnly yes
