[Oisf-users] Netmap pipe configuration

[James Dickenson]

Hey All,

I'm trying to test a Suricata configuration using Netmap and the bundled
Netmap tool lb to load balance for the Suricata worker threads.  However
I've run into some trouble trying to figure out how to get Suricata to bind
to the netmap pipes.

Anyone have any experience with using Netmap with Suricata? Or for that
matter used the lb to do load balancing?

Thanks in advance for the assistance!

I can do the following:

# lb -i ens1f1 -p foo:4

and can bind to any of the four pipes using the netmap tool pkt-gen:

# pkt-gen -i foo}0 -f rx

But if I try on Suricata:

# /usr/bin/suricata  -c /etc/suricata/suricata.yaml --netmap=foo}0
--runmode=workers
