Hello. I have a doubt about PF_RING and DNA/libzero so I need some help.
I was reading the UsersGuide of PF_RING but I still don't know if I can use
just PF_RING or if I need to use Libzero for DNA:
I want to implement an external Fault Injector.
The idea is this: I intend to use 3 computers A,B (midle, with interfaces dna0
(RX0 e TX0 queues) and dna1(RX1 e TX1 queues) and C: Computer "A" will have a
conection to the dna0 interface and computer C, will have a conection to the
interface dna1. The computer B will have a fault injector application.
This fault injector aims insert faults in the communication packages between
the computers A and C.
My doubt is if this is possible:
Computer A sends a message to computer C. Computer B receives the message at
RX0 queue, inserts the fault in the message and sends it to computer C using
the TX1 queue.
And the opposite:
Computer C sends a message to computer A. Computer B receives the message at
RX1 queue, inserts the fault in the message and sends it to computer A using
the TX0 queue.
Someone could help? Is this possible to do with PF_RING Vanilla or I need to
use DNA/Libzero?
Thanks a lot for your time and patience in helping me.
Best regards,
Rodrigo.
