how to log a mark'ed packet in iptables?

[Joseph Mack <mack.joseph@xxxxxxx>]

I want to LOG packets with a fwmark. I can't get the syntax right.
Here's one of my attempts to log all packets with fwmark==1. All
get a syntax error.

$iptables --mark 1 -j LOG --log-level DEBUG --log-prefix "fwmark 1: "

I've tried about a dozen combinations using the typewriter-monkey-sonnet
principle but haven't found how to do it.

Thanks
Joe
