In the SSH protocol, the authentication callback is an important link, which is used to verify the client's identity and establish a secure connection.

Question content

My server configuration code is:

serverConfig := ssh.ServerConfig{
        PublicKeyCallback: func(c ssh.ConnMetadata, pubKey ssh.PublicKey) (*ssh.Permissions, error) {
        ...
    }
}

I start the ssh connection using something like ssh://user@host:port/path. How do I get the path part of the ssh connection string in this callback or any other callback that can check the user key/password?

Solution

SSH is different from http, which contains ssh://user@host:port/path. The format is indeed user@host:port but it does not require ssh:// and path construction. In your question, PublicKeyCallback is using the public key. If you are performing a custom action, do it outside of PublicKeyCallback.
