Lock IP address

[akoenig]

When the initial agent connects, the user should be asked on the host if they accept this connection. If accepted, no other IP address is allowed to connect during that session. The session is locked then.

Thanks for opening this issue! I’ve just submitted a PR to implement the IP locking behavior: #13

This change prompts the host to accept the initial agent connection, and once approved, locks the session to that specific IP so no other addresses can connect during that session. Let me know what you think or if there are any adjustments needed!
