SSH 客户端未在 ssh-agent 中尝试我的密钥

Question

我使用的是 OS X Yosemite 10.10.5，并且我的 SSH 客户端的行为方式我无法解释或解决。

我的目标只是通过以下方式连接到服务器：

ssh -A core@12.34.56.78

当我添加-v此内容时，我可以看到我的 SSH 客户端无法尝试除我的~/.ssh/id_rsa密钥之外的任何密钥。我已经确认 ssh-agent 正在运行，并用于ssh-add -l确认我想要的密钥已添加。

这是我在本地 bash 提示符中运行的内容：

# Run ssh-agent
bash-3.2$ eval $(ssh-agent)
Agent pid 7786

# Confirm it's running
bash-3.2$ sudo ps aux | grep ssh-agent
josh             7794   0.0  0.0  2432772    676 s000  S+    1:32PM   0:00.00 grep ssh-agent
josh             7786   0.0  0.0  2480640   2180   ??  Us    1:31PM   0:00.04 ssh-agent

# Login successfully by explicitly specifying a key
bash-3.2$ ssh -i sandbox core@12.34.56.78
Last login: Tue Aug 18 20:13:31 2015 from X.Y.189.46
CoreOS stable (723.3.0)
core@ip-10-200-4-138 ~ $ exit
logout
Connection to 12.34.56.78 closed.

# Now attempt to connect using ssh-agent
bash-3.2$ ssh-add sandbox
Identity added: sandbox (sandbox)
bash-3.2$ ssh -A core@12.34.56.78

# My just-added key isn't tried, so I'm prompted for a password
core@12.34.56.78's password:

任何帮助将非常感激！

更新： 根据要求，这是详细输出：

Answer 1

密钥是sandbox版本 1 还是版本 2？如果它是旧密钥，则它可能仅适用于 ssh 协议的版本 1。您可以通过运行来解决这个问题ssh -A -1 core@52.26.187.69。
