ssh-agent

在.bashrc中添加下面的命令就可以启动ssh-agent,用eval的原因是需要设置环境变量

eval "ssh-agent -s"
## ssh-agent bash

如果echo $SSH_AGENT_SOCK有值就说明启动成功,可以通过下面的命令查看所有添加的密钥

ssh-add l

如果报错,用ssh-agent bash解决

Could not open a connection to your authentication agent.

sshd

sudo apt install openssh-server
sudo systemctl status openssh-server
sudo systemctl start openssh-server

配置文件/etc/ssh/sshd_config
