HaProxy Multiplexing

menetas

Hi, I wonder is there a way to duplicate tcp traffic from specific port to a remote server using haProxy or any other way..

Im receiving tcp traffic to port 14000…
Then I want to duplicate this traffic to local port 14001 and to remote server port 14000..

I successfully can do that but haproxy will split traffic to two servers using the balance options supported by it... (roundrobin, static-rr, source, etc)..

So I get more traffic to one of the servers than the other..

What I really need is to receive a copy of the incoming 14000 port in the remote server in the same port 14000..

Is there a way to do this??

Here's my current config (the one that splts in half the traffic)

global
maxconn 100000
user root
group root
daemon

defaults
mode tcp
option dontlognull
retries 3
option redispatch
contimeout 5000
clitimeout 50000
srvtimeout 50000

listen localhost 0.0.0.0:14000
mode tcp
balance static-rr
maxconn 100000

server remote 99.99.99.99:14000 check
server local 127.0.0.1:14001 check

Any help would be very appreciated..

Thanks in advance

haproxy is not designed to duplicate/copy traffic to a secondary server. without modifications to the program it will not be possible with that.
(it has been asked for on the haproxy mailinglist.. but i cant find the thread currently..)
