How to Run
Here is how to run the Slackware 14.2 : Slackware 14.2 kernel (SSA:2021-202-01) as a standalone plugin via the Nessus web user interface (https://localhost:8834/):
- Click to start a New Scan.
- Select Advanced Scan.
- Navigate to the Plugins tab.
- On the top right corner click to Disable All plugins.
- On the left side table select Slackware Local Security Checks plugin family.
- On the right side table select Slackware 14.2 : Slackware 14.2 kernel (SSA:2021-202-01) plugin ID 151897.
- Specify the target on the Settings tab and click to Save the scan.
- Run the scan.
Here are a few examples of how to run the plugin in the command line. Note that the examples below demonstrate the usage on the Linux / Unix platform.
Basic usage:
/opt/nessus/bin/nasl Slackware_SSA_2021-202-01.nasl -t <IP/HOST>
Run the plugin with audit trail message on the console:
/opt/nessus/bin/nasl -a Slackware_SSA_2021-202-01.nasl -t <IP/HOST>
Run the plugin with trace script execution written to the console (useful for debugging):
/opt/nessus/bin/nasl -T - Slackware_SSA_2021-202-01.nasl -t <IP/HOST>
Run the plugin with using a state file for the target and updating it (useful for running multiple plugins on the target):
/opt/nessus/bin/nasl -K /tmp/state Slackware_SSA_2021-202-01.nasl -t <IP/HOST>
Go back to menu.
