cannot decode data link type 239

[Sharif Uddin <Sharif.Uddin () spectrumasa com>]

Hello

I have had snort running for a while without problems, just recently it has not logged anything which is weird. When I 
done strace on snort I found the following problem


socket(PF_INET, SOCK_DGRAM, IPPROTO_IP) = 4
ioctl(4, SIOCGIFADDR, {ifr_name="nflog", ???}) = -1 ENODEV (No such device)
close(4)                                = 0
write(2, "ERROR: Cannot decode data link t"..., 40ERROR: Cannot decode data link type 239
) = 40
write(2, "Fatal Error, Quitting..\n", 24Fatal Error, Quitting..



I have googled this and all answers point to running extra command on build. But my snort was running fine, which does 
not make sense


I use following to run snort


snort -q -u snort -g snort -c /etc/snort/snort.conf -i ens34 -D
barnyard2 -c /etc/snort/barnyard2.conf -d /var/log/snort -f snort.u2 -w /var/log/snort/barnyard2.waldo


how do I fix this
