Hello,

To replay all incoming traffic on my infrastructure, i have a Centos 6 server attached to a mirroring port.
I see on this server all traffic in promiscuous mode and i'd like to forward this traffic to another host.

How can y do ?

Thanks

Use nc

"Dunno, just think about it ..."

It's quite possible to arrange for one host to "promiscuously gather all of the traffic that it sees," and then to "send it [all] to another host," but, if you simply forward it (as though you were merely a "gateway"): "now, what-in-the-heck is this 'another host' now supposed to do with all this stuff?" If this is, indeed, your intention, then you'll need to be sure that the recipient is prepared with all of the necessary routing-rules.

On the other hand, perhaps you intend for the promiscuous host to gather all of the incoming messages, and then to send new messages (containing the content of the messages it has received...) to its peer.

The "proper" answer to your question rests upon this clarification . . . .

I might be tempted to run a GRE tunnel.

Another possibility is to set up an OpenVPN tunnel betwixt them, running in "bridge mode."

In this mode, the connected peers will promiscuously listen on their respective networks and inform one another of what they hear, to be re-broadcast upon the other network. But the connection between them is secure. No one can eavesdrop on the traffic or inject forged traffic into the conversation. The two peers recognize one another using one-of-a-kind digital certificates issued only to them.
