There is life !!! :D
How do I go about duplicating a UDP packet arriving at a machine.
Essentially I want to have it go to its original recipient but to
another new one also.
-j ROUTE --tee seems not to be supported anymore.
False... It is supported but you need the patch-o-matic(-ng) stuff...
--tee Make a copy of the packet, and route that copy to the
given destination. For the original, uncopied packet, behave like a
non-terminating tar-
get and continue traversing the rules. Not valid in
combination with `--iif' or `--continue'
Getting this to work for a novice like me seems to be impossible.
Doing a man on my FC5 system shows --tee to be there under the ROUTE
extension and I quote from the man page
'iptables can use extended target modules: the following are included in
the standard distribution'
however using iptables results in
[root@nst2 ~]# /sbin/iptables -A PREROUTING -t mangle -p udp -d
192.168.3.77 --dport 9090 -j ROUTE --tee
iptables v1.3.5: Unknown arg `--tee'
locate libipt_ROUTE.so yields nothing which makes me believe the man
page was talking bollocks when claiming the extensions to be part of the
'standard distribution'
After further reading I also came to the conclusion patch-o-matic needed
to be used to install the ROUTE module. going to netfilter extensions
HOWTO I see I have to get the latest update from CVS like in so
cvs -d :pserver:cvs@xxxxxxxxxxxxxxxxxxxxx:/cvspublic login
but when I do this with password cvs I get
[root@nst2 ~]# cvs -d :pserver:cvs@xxxxxxxxxxxxxxxxxxxxx:/cvspublic login
Logging in to :pserver:cvs@xxxxxxxxxxxxxxxxxxxxx:2401/cvspublic
CVS password:
cvs [login aborted]: connect to
pserver.netfilter.org(213.95.27.115):2401 failed: Connection refused
any ideas ?
