| This target marks packes so that the kernel will log every rule which match |
| the packets as those traverse the tables, chains, rules. |
| .PP |
| A logging backend, such as ip(6)t_LOG or nfnetlink_log, must be loaded for this |
| to be visible. |
| The packets are logged with the string prefix: |
| "TRACE: tablename:chainname:type:rulenum " where type can be "rule" for |
| plain rule, "return" for implicit rule at the end of a user defined chain |
| and "policy" for the policy of the built in chains. |
| .br |
| It can only be used in the |
| .BR raw |
| table. |
