It seems that libzero is another > licensing option? I mean I can't have two sniffers running without libzero? DNA is a kernel-bypass technology that takes direct control over the NIC from userspace, this means that a single process can open a DNA device (or RSS queue) at the same time. Libzero is a library sitting on top of DNA, able to distribute packets coming from a DNA adapter in zero-copy to multiple threads/processes. This means that you need Libzero to capture from the same interface from two sniffers. > I could try using another port on two-port 10G card and buy another DNA > license (I think that would be better than having DNA + libzero).
