我无法SSH到digitalocean上的服务器。我在要访问的服务器上添加了公钥。我正在Windows上使用Git。使用Windows7。我已在GIT的ssh_config文件中禁用了StrictHostKeyChecking。 ssh代理正在运行。还使用ssh-add命令将密钥添加到代理，它可以正确显示我的私钥。我的私钥名称是ct_devops，而不是id_rsa，这是问题吗？ 请在下面找到ssh -vT“ hostname”命令的输出：

有人可以帮助您确定需要做什么或我做错了什么吗？ 我检查了其他答案并尝试了所有可能性，但仍然无法正常工作。
答案 0 :(得分：0)
我只在Linux和OS X上进行了测试，但与直觉相反的答案是这样的（将首先说明解决方案，然后解释其工作原理）：
使用-i。我不知道Windows的确切语法差异，但是在* nix系统上，我会这样做：
ssh -i / path / to / publickey root @ dropletip
将根ssh密钥复制到您要以以下身份登录的用户：
cp〜/ .ssh / 。 / home /我的用户/.ssh获取
重新启动ssh守护程序（这取决于远程服务器上的Linux发行版）
从理论上讲，这是可行的，因为已使用正确的ssh密钥凭据设置了根帐户（假设在创建Droplet时已正确设置了它们）。您的新用户帐户还没有。
现在，您对使用ssh-sing的用户的问题尚不完全清楚。必须有一个，并且您首先需要以root用户身份进行操作，而不仅仅是创建非root用户。还有其他一些潜在问题：
