私はこの質問が何度も要求されたことを知っており、誰もが最善の答えを試しましたが、まだ答えを得ることはできません。同様のファイルが見つからないと言いますが、/home/valachio/.ssh/id_rsaサーバーを確認してみると、すべてのファイルが明らかに存在します。
生成されたSSHキーを試してみましたが、ssh-keygenPuTTYで生成されたSSHキーも試してみました。 SSHキーが正しくauthorized_keys保存されました/home/valachio/.ssh/。キー形式を確認しましたが、正しいです。それssh-rsa (keyname) valachio@(myserverhost)
これを行うと、エラーメッセージは次のようになります。ssh -vT [email protected]

公開鍵がありませんid_rsa.pub。以下は、サーバーで公開鍵と秘密鍵のペアを生成する例です。
$ ls -ltrh .ssh/
-rw-r--r--. 1 root root 394 Jul 18 23:49 known_hosts
$ ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa): Enter passphrase
(empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:

-rw-r--r-- 1 root root 395 Jan 12 22:13 id_rsa.pub
id_rsa.pub次のステップは、リモートサーバーにファイルをコピーして~/.ssh/authorized_keysコマンドssh -vvを再試行することです。
