我想从笔记本电脑 ssh 到 COMPUTE，但必须通过登录，并且 COMPUTE 和登录共享用户（因此没有单独的 ssh 配置）。
这个问题类似于这个例外的是，就我而言，我的服务器是登录/计算设置的。因此，堡垒（登录）和目标（计算节点）上的用户帐户/用户目录是相同的。 LAPTOP 无法直接 ssh 进入 COMPUTE，而必须通过 LOGIN。
LAPTOP --> [LOGIN --> COMPUTE]
| ^
+------------ X ---------+
在LAPTOP（Windows）上，我有以下 .ssh/config：
Host loginnode
HostName login.company.org
User bramvanroy
IdentityFile ~/.ssh/mycompanykey
Host computenode
HostName compute.company.org
User bramvanroy
IdentityFile ~/.ssh/mycompanykey
ProxyJump loginnode
在 上LOGIN，有它自己的配置，如下所示：
Host computenode
HostName compute
User bramvanroy
ForwardAgent yes
权限：
authorized_keys: 600config： 644
虽然我确实可以在没有密码的情况下从笔记本电脑 ssh 登录 ( ssh loginnode)，但当我尝试时ssh computenode，仍然要求我输入密码。
这是为什么？我该如何解决这个问题？
同样，据我所知，我无法在登录/计算之间使用中间 SSH 密钥，因为它们都使用相同的帐户和配置。
输出ssh -vvv computenode（真实姓名/IP地址不同）：

它尝试连接回您的 SSH 代理，但套接字似乎不存在。
您确定代理正在运行吗？

系统管理员让我知道问题是COMPUTE没有use_nfs_home_dirs启用 SELinux 参数。启用后，现在一切都按预期进行。
