Re: MAC Address In Logs

Hi Chris,

I only see these headers for conn.log:
#fields ts uid id.orig_h id.orig_p id.resp_h id.resp_p proto service
duration orig_bytes resp_bytes conn_state local_orig local_resp missed_bytes
history orig_pkts orig_ip_bytes resp_pkts resp_ip_bytes tunnel_parents

Using the same commands I always use: sudo ./bro -C -r
~/Desktop/pcap/test.pcap

Wireshark shows MAC just fine.  I don't need to rebuild bro again, right?
Just need to edit the /usr/local/bro/share/bro/site/local.bro file.  The
only file that shows a column for mac is the dhcp.log

Thanks,
