iptables logging doesn't log

I'm trying to log any requests to port 22 into my syslog, so I have following line in my iptables:

LOG        tcp  --  anywhere             anywhere            tcp dpt:ssh LOG level debug 

yet, when I ssh in, nothing gets logged. I'm using RHEL6 (6.2)

Any ideas why?

I've used the following to log new connections to port 22

iptables -I INPUT -p tcp -m tcp --dport 22 -m state --state NEW  -j LOG --log-level 1 --log-prefix "New Connection "

This rule only logs new connections to port 22. It logs to /var/log/messages on the CentOS box I have to hand

Note that iptables actions rules in the order they are defined so if you used iptables -A to add your rule to an existing ruleset then it's possible that packets are being accepted or denied by an earlier rule and your log action is never erm actioned.
