Question

I want to store the output of iptables -vL command into a mysql database table. When I run iptables -vL it shows usage in bytes along with users MAC id’s. I am planning to use awk to select two columns (usage “$2” and MAC id’s “$6”) from the output of the above command. And those two clomuns should go to the database. The usage column in the database should add up whenever the tables are updated.

Answer 1

When parsing the iptables output with awk, format it out as Mysql INSERT statements, and then pipe the results into the mysql command line. Something like:

iptables -vL | awk {your awk commands here} | mysql --user=foo --password=bar yourdatabasename
