SSH setup and logging on GNS3

1- Configured remote access on Router 1 (SSH 1.99).

2- Enabled login on-success log and login on-failure log commands to track and log both successful and failed login attempts. This provides a clear record for monitoring and auditing security events.

3- Set up a security feature that locks Router 1 for 120 seconds if someone fails to enter the correct password more than 3 times in 60 seconds (Quiet Mode).

4- Created an Access Control List (ACL) to exclude Router 4 from the Quiet Mode, ensuring it could always connect.
