Betreff: [Ntop-misc] n2disk/disk2n: Problem with PF_RING ZC
Hello.
I want to maximize the performance for n2disk/disk2n and use PF_RING ZC.
PF_RING only is working as expected, but this doesn't:
[root@myhost]# pfcount -i zc:eno1
pfring_open error [No such device] (pf_ring not loaded or interface zc:eno1 is
down ?)
[root@myhost]# pfsend -i zc:eno1
Sending packets on zc:eno1
pfring_open error [No such device] (pf_ring not loaded or interface zc:eno1 is
down ?)
