どういうわけか、私のSSHはパスワードの入力を決して望みません。
だから私は世界のどこかにあるランダムなサーバーにVPSをセットアップし、sshでそれに接続したい。
キーをセットアップできますが、これを行うと:
ssh -l some-user IP
エラーが表示されます:
Received disconnect from ##.##.##.##: 2: Too many authentication failures for some-user
詳細を見ると、パスワードがオプションの1つであることがわかります。
debug1: Offering RSA public key: some-user@computer
debug1: Authentications that can continue: publickey,password
しかし、SSHはパスワードの入力を決して求めません。publickeyメソッドと思われるもので5回試行した後、失敗します。sshがパスワードを試さないのはなぜですか?!
念のため、私のssh_configファイルには次のものがあります。
PasswordAuthentication yes
