Ok I have the following problem.
iptables -A OUTPUT -o ppp0 -p tcp -m length --length :40 -j MARK --set-mark 10
That should mark all ACK's or not ?
When I try to do this I get the error:
iptables: Invalid argument
[...]
So now my question is what am I doin wrong ?
Typically when the only error message from iptables
is 'Invalid Argument', the actual error message would
be most of the time in the kernel log.
i.e. If I run your command above, it tells me
# dmesg
MARK: can only be called from "mangle" table, not "filter"
Hmm forget to look there (Just a newbie ;)
So, you should be using a -t mangle in front..
Thx that did it.
Have a nice day,
You too.
