Gentoo-ssh-Agent Configuration

Currently, SSH key authentication is usually configured for services like GitHub.

Therefore, it is necessary to use SSH-agent to manage the private key.

In Gentoo, the configuration is as follows:

-Sudo emerge-AVT keychain

-Edit. bashrc and add the keychain <private key 1 path>... <private key N path>

-Edit. bashrc. After the preceding sentence, add source $ home/. keychain/$ hostname-sh.

Tools similar to ssh-add require environment variables such as ssh_auto_sock to know the ssh-agent information. The keychain has been generated for us, so we need the above sentence source, refer to man keychain

 

Keychain is an SSH-Agent wrapper. Its function is as follows:

-Ensure that only one ssh-Agent process exists.

-Automatically generate settings for environment variables such as ssh_auth_sock.
