[Oisf-users] Problems with BPF filter in Gentoo

[Duarte Silva]

Hi all,

I have been having problems using Suricata on my Gentoo machine. The error is 
as it follows in the attachments. This also happens if I use a wired network 
interface or even if I use pcap capture mode (log file is for af-packet).

I have also attached some files that might help debugging the problem.

Thanks in advance,
Duarte Silva
