我使用 ssh-keygen 在我的机器上创建了一个密钥。我使用 ssh-copy-id 将密钥复制到远程计算机。
尝试连接到远程计算机，但它询问我密码。两台机器都是ubuntu（本地11.04，远程8.04）

好的。我注意到这里有一些东西。我正在查看 ~/.ssh/authorized_keys 并意识到在密钥末尾写着这样：
me@my_computer_name
代替：
me@my_computer_ip
我不知道是否与此有关，但是...
答案1
答案2
您的密钥名称是否与 id_rsa、id_dsa 或 id_ecdsa 不同？
默认情况下，ssh 将仅尝试使用这些密钥名称。如果您选择了另一个，不用担心，您可以使用 -i 指定密钥名称，也可以在 ~ssh/config 文件中一劳永逸地指定它。
使用 -i 的示例（也许您需要在密钥名称之前添加 ~/.ssh/ ，我不记得了）：
ssh -i <your_priv_key_name> [email protected]
~/.ssh/config 示例
Host 192.168.1.217
IdentityFile ~/.ssh/<your_priv_key_name>
答案3
假设“myuser”是远程系统上的有效用户，则密钥需要放置在该用户的 ~/.ssh/authorized_keys 中（如果使用默认配置）。
检查远程服务器上的 sshd_config 以确保 authkey 文件应该是什么，查找行AuthorizedKeysFile.
