Hello sir, The command with the '-l' argument, is that auditctl? The command with the '-s' argument... what is that one called, auditd?
Thanks for replying so quickly, sorry for being a nag.

There is a rule listing command, -l, that will dump what the kernel has loaded. There is also a status command, -s, that will tell you if audit is enabled. If the rules are loaded and audit is enabled, its working. > Also, being a total novice, how can I test/trigger audit log actions > on watch and action rules to see that the rules are configured properly? If its a watch, then accessing the file and running ausearch should do it. If you have a syscall rule, then you have to trigger the syscall either by using a program or creating one. > Finally, is there a tool that will do a sanity check on the audit.rules file? auditctl reports any problems that it sees with the rules. > Or is the only option to attempt to restart the auditd service, and > think "It started, it worked!" is acceptable? List the rules and status the audit subsystem. -Steve -- Linux-audit mailing list [email protected] https://www.redhat.com/mailman/listinfo/linux-audit
