authorized_keys介绍: authorized_keys 是linux 操作系统下,专门用来存放公钥的地方,只要公钥放到了服务器的正确位置,并且拥有正确的权限,你才可以通过你的私钥,免密登录linux服务器 我们来看一下普通的authorized_keys 长的什么样子: ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAACAQCzch9SZMR7rCu3FPU6doJrSMN75sIE/YciTP...
The ssh-agent is a helper program that keeps track of users' identity keys and their passphrases. The agent can use the keys to log into other servers without having the user type in a password or passphrase.

I observed same. ssh-agent is working but it gives error when trying to add keys or list keys. But, once I connect to company network via VPN, it starts working. Is there a fix for this issue? This seemed to fix things, why this is required is puzzling at best ...

可以看到,服务器可以在authorized_keys文件中维护多个公钥文件,当收到客户端请求的时候,如何确定使用哪个公钥呢?从代码中可以看到,当客户端连接过来的时候,会带上签名的指纹(fingerprint),而服务器计算自己管理的所有公钥文件的指纹进行匹配,匹配之后使用该公钥进行验证。
