Hi Spiros,

Did you install i40e-zc and pfring-drivers-zc-dkms packages together with pfring and pfring-dkms?

What Linux distro are you running?

Hi all,

I'm running into problems with installing nscrub.

While, i had made it start succesfully, it has stopped working....

I have updated and removed/reinstalled pfring/dkms.

Thank you,

Spiros

following errors:

Hi all,

Problem solved! Thanx for your guidance:
It needed:
 touch /etc/pf_ring/forcestart


I had configured though, interfaces.conf:
MANAGEMENT_INTERFACES="ens192"
CAPTURE_INTERFACES="ens160"

For reference:
I am on LTS16, and I have upgraded it to date.

I have these installed:
pfring/unknown,now 7.1.0-1566 amd64 [installed]
pfring-dkms/unknown,now 7.1.0 all [installed]
pfring-drivers-zc-dkms/unknown,now 1.3 all [installed]
i40e-zc-dkms/unknown,now 2.3.6.1566 all [installed]
