Description

When you run suricata + pf_ring without specifying the interface in command line, this error appears:

26/8/2013 -- 12:49:24 - <Info> - This is Suricata version 1.4.5 RELEASE
26/8/2013 -- 12:49:24 - <Info> - CPUs/cores online: 8

26/8/2013 -- 12:49:24 - <Info> - Failure when trying to get MTU via ioctl: 19

Specifying the interface, it works:

[root@nsm01 init.d]# LD_LIBRARY_PATH=/opt/pfring/lib suricata --pfring-int=eth3 --pfring-cluster-id=99 --pfring-cluster-type=cluster_flow c /data/config/etc/suricata02/suricata.yaml -D

Can someone with pf_ring check if that's still an issue?

With pfring and 3.1dev (rev ae11687) it seems to be ok but the MTU it is not reported :
