Hi,
I'm using on my server Debian stable with iptables. I've configure
traffic control (command tc from iproute2) based on filter fw (marked
packages from iptables). I have advanced router with failover and 4
network interfaces and I had to define more than one marking rule.
e.g.
iptables -A PREROUTING -t mangle -i eth0 -j MARK --set-mark 10
I've defined too rule for loggin results:
iptables -t mangle -A PREROUTING -i eth0 -m limit --limit 1/s -j LOG
--log-prefix "mark testMN prerouting 10 " --log-level debug
--log-ip-options --log-tcp-options
and I've found in syslog

but I can't find iformation about my marker value 10.
Please give me a solution, how can I investigate in log files packages
with their marker-value.
