Hi all, Finally I have a snort_inline 2.8.2.1 sensor with nfqueue support installed on my laptop and integrated with ossec ... But I have two questions: - Some recommendations about kernel params like Victor Julien publish in his blog: http://www.inliniac.net/blog/2008/01/23/improving-snort_inlines-nfq-performance.html?? - And a funcionality question: sometimes appears in snort's alert log entries like this: [**] [116:150:1] (snort decoder) Bad Traffic Loopback IP [**] [Priority: 3] 07/04-17:44:56.578830 127.0.0.1:55363 -> 127.0.0.1:25 TCP TTL:240 TOS:0x10 ID:0 IpLen:20 DgmLen:46 ***AP*** Seq: 0x2CB755E Ack: 0x339A7A9 Win: 0x8480 TcpLen: 20 This alert is relative to my postfix local smtp server ... How can I disable this type of alerts (only for 127.0.0.1 ip)?? Many thanks to all ...
Please any hints??
