git - ssh 代理转发不适用于 ec2

Question

我正在尝试在我的本地机器上使用 ssh 代理转发，这样我就不必在远程服务器上使用我的私钥进行 git clone git@bitbucket.org:username/bucketname.git

我的机器上有以下设置:

 $cat ~/.ssh/config
    Host bitbucket.org
     IdentityFile ~/.ssh/id_rsa

    Host 172.28.128.3
     ForwardAgent yes

并将我的公钥添加到 bitbucket 站点

当我运行 ssh -T git@bitbucket.org 时显示

logged in as <username>.
You can use git or hg to connect to Bitbucket. Shell access is disabled.

意味着 ssh 协议(protocol)工作正常，我可以克隆任何 repo。

但是当我在我的远程机器/主机上运行时(在 .ssh/config 文件中提到，ip 为 172.28.128.3)

我正在使用 ec2 实例作为远程机器。

请帮我解决这个问题。

我强烈推荐此链接来设置 ssh 转发代理 Guide for SSH Agent Forwarding

尝试像这样解决问题:

1. 检查您是否在本地机器 .ssh/config

中写入了正确的主机 IP

2. 在您的本地机器上，运行此命令 --> echo "$SSH_AUTH_SOCK"

2.1。如果这给出空响应，则执行此操作:eval `ssh-agent -s` && ssh-add -k

1. 现在一切正常
