`ssh`客户端不提供我的代理中的第二个密钥，只提供我的默认密钥 – 发生了什么事？

我的代理中有第二个SSH密钥，我用ssh-add 。 它是在我的默认密钥后面，它位于~/.ssh/id_rsa 。

我有一个服务器，有第二个密钥的公钥添加到它的authorized_keys文件，我希望我的代理提供第二个密钥时，SSH的。

但是，它不。

ssh-add -l （带适当的审查）：

• 电子邮件安全思想证书
• Samba 4.5.1 Windows 2012R2 LDAP
• Google Cloud VM CPU使用率中有99％以上的峰值是多less？
• IP表是在Ubuntu 14.04中保留的
• 有没有办法从iptables转发所有stream量到我的IDS Suricata在第二个界面？

 $ ssh-add -l 2048 SHA256:y17xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxM1f8GvLwzU /home/user/.ssh/id_rsa (RSA) 4096 SHA256:6sOpxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxCeSXgu1vI /home/user/.ssh/id_rsa-another-key (RSA) 

它具有正确的权限：

 $ ls -l ~/.ssh/id_rsa-another-key -rw------- 1 user user 3326 Nov 22 11:08 /home/user/.ssh/id_rsa-another-key 

当我尝试login到服务器时，带有-v标志的ssh输出是问题的结尾。

谁能告诉我为什么SSH不会很好地提供第二个关键，就像它应该？

==========更新1 =========

我已经尝试用-i传递正确的密钥，然后我得到一个密码。 在这种情况下，使用-vvv它使用该密钥，而不是来自代理的密钥。

ps -p $SSH_AGENT_PID显示ssh-agent正在运行，而不是桌面的自定义实现
