Hi all, As I have described in a previous email, I have installed Snort 2.9.9.0p0 in an OpenBSD 6.2 host. After resolve how to apply packet normalization policy in snort.conf, I have another problem: all downloads are stalled randomly. My startup flags for snort are: -D -c /etc/snort/snort.conf -u _snort -g _snort -t /var/snort -l /var/snort/log --pid-path /log --no-interface-pidfile --nolock-pidfile -Q DaQ config is: config policy_mode: inline config daq: ipfw config daq_dir: /usr/local/lib/daq/ config daq_mode: inline config daq_var: port=9000 Packet normalization policy: preprocessor normalize_ip4 preprocessor normalize_tcp: block, rsv, pad, urp, req_urg, req_pay, req_urp, ips, ecn stream preprocessor normalize_icmp4 preprocessor normalize_ip6 preprocessor normalize_icmp6 OpenBSD's pf config for divert sockets is: pass out quick inet proto tcp all flags S/SA keep state (if-bound) scrub (reassemble tcp) tagged intlans-to-inet divert-packet port 9000 pass out quick inet proto icmp all keep state (if-bound) scrub (reassemble tcp) tagged intlans-to-inet divert-packet port 9000 pass out quick inet proto udp all keep state (if-bound) scrub (reassemble tcp) tagged intlans-to-inet divert-packet port 9000 Snort is installed from OpenBSD's ports. Do I need to modify some option in normalization or stream5 policy?? (Stream5's policy is the default) Thanks. -- Greetings, C. L.
