Ubuntuサーバーに問題があります。このサーバーから2番目のサーバーにSSHを試みると、次のエラーが発生します。

しかし、/home/federico/.ssh/でid_rsaを見ることができます。

federico@federico:~/.ssh$ ls -l

-rw-r--r-- 1 federico federico  1265 Jun 29 14:10 config

-rw-r--r-- 1 federico federico  9682 Jun 30 09:04 known_hosts.old

私はこのエラーを調べましたが、誰もが異なる提案をしましたが、その解決策は私にはうまくいきませんでした。どんなアイデアがありますか？

ありがとう

キーを読み取って保護する必要があります。

chmod 600 .ssh/id_rsa
