Hi,
my iptables is version 1.2.7a and I have to use version 1.2.9 for a project. I have downloaded the 1.2.9 version and 'run' the new version without deleting the old one. But when I insert iptables rules, it still uses the old version. Do I have to delete the version 1.2.7a or are there any commands to install the newer version? The actual error message I got was

Using /lib/modules/2.4.20-8custom/kernel/net/ipv4/netfilter/ipt_modbus.o
Enabling forwarding...
iptables: match `modbus' v1.2.9 (I'm v1.2.7a).
iptables v1.2.7a: unknown protocol `tp' specified
Try `iptables -h' or 'iptables --help' for more information.

I have intentionally put a wrong spelling of tcp in the iptables ruleset. Does that mean that I'm running on the iptables 1.2.7a version?
Thanks for your advice.

Yes, that's what it means ... as for the upgrade:
depends on the distro you're using.

Thanks.

I have deleted the iptables version 1.2.7a by using
#rpm -e iptables

and then installed (make) the iptables version 1.2.9
When I type
#iptables -V
I get
iptables v1.2.9

But when I use
#rpm -q iptables
the response was package iptables is not installed.
I cannnot even do
#service iptables start
Bad argument `start'
Try `iptables -h' or 'iptables --help' for more information.

I don't understand the problem, have I not installed the iptables version 1.2.9? What should I do?

You most likely DO have 1.2.9 installed ... however,
it's a) not registered with rpm since you installed from
source, and b) most likely in a spot where the scripts
won't find it, e.g. /usr/local/sbin rather than /usr/sbin.

I'd suggest trying to find an rpm
and install that instead ...
