I have a list of my nessus scanners in my /etc/snort/bpf_file but they're still triggering alerts. I've got them listed in the following syntax for example: not (src host 10.10.1.1) && not (src host 10.10.1.2) && not (src host 10.10.1.3) And my snort process is pointing to it: /usr/sbin/snort -D -i eth6 -u snort -g snort -c /etc/snort/snort.conf -l /var/log/snort/eth6 -F /etc/snort/bpf_file And it shows up in the syslog when snorts starts: Jan 29 16:15:53 nids1 snort[940]: Reading filter from bpf file: /etc/snort/bpf_file Jan 29 16:15:53 nids1 snort[940]: Snort BPF option: not (src host 10.10.1.1) && not (src host 10.10.1.2) && not (src host 10.10.1.3) But the alerts keep streaming in (not just this alert): 01/29-16:36:28.235294 [**] [1:2003068:6] ET SCAN Potential SSH Scan OUTBOUND [**] [Classification: Attempted Information Leak] [Priority: 2] {TCP} 10.10.1.1:49870 -> 10.10.1.43:22 This is snort 2.9.4.0 on CentOS 5.x. What am I doing wrong? Thank you! MA
