ssh-agent如何设置和使用SSH_AUTH_SOCK? [英] How is SSH_AUTH_SOCK setup and used by ssh-agent?

问题描述

阅读 https://superuser.com/之后，我已经能够设置ssh-agent的共享以进行公钥身份验证a/230872/301446

这样生成的环境文件具有以下内容:

The environment file thus generated has the following contents:

SSH_AUTH_SOCK=/tmp/ssh-OwqeSuxmEsQN/agent.4744; export SSH_AUTH_SOCK;
SSH_AGENT_PID=8960; export SSH_AGENT_PID;
#echo Agent pid 8960;

agent.4744具有:

!<socket >24194 s 07DF88C6-E9997283-4C471010-2FE57D77

您知道ssh-agent如何使用此套接字吗?我可以理解ssh-agent使用它共享身份验证信息，但具体如何呢?

Would you know how this socket is used by ssh-agent? I can understand that it's used by ssh-agent to share authentication information but exactly how?

推荐答案

来自此处:

$ SSH_AUTH_SOCK包含unix文件套接字的路径， 代理用于与其他进程进行通信.这是必不可少的 用于ssh-add.

$SSH_AUTH_SOCK contains the path of the unix file socket that the agent uses for communication with other processes. This is essential for ssh-add.
