Yeah, it looks that way. Fixed.

Yes. > How do these rules 'work' to suppress chrony time updates from being > logged? The audit rules is a first match wins system. These rules are in a file with a 22 in the name which preceeds rules whose file name starts with 30. In 30- stig.rules, we have a rule that asks for any use of adjtimex to be logged which is the syscall chrony uses to update time. Since the rule in 22 has a never action and it preceeds the one from the stig, it matches first and takes the never action which is not to log it. -Steve -- Linux-audit mailing list [email protected] https://www.redhat.com/mailman/listinfo/linux-audit
