Improve IP resolution and add retry mechanism

- Modified the IP resolution process to allow for multiple attempts with a specified interval.
- Added a retry mechanism to check the IP address multiple times before considering it unsuccessful.
- If the target IP cannot be found after the specified number of attempts, an error message is displayed.
- Updated the SSH command to run the alarm script in the background.
