running snort 2.9.4.1 i'm seeing a lot of [129:20:1] TCP session without 3-way handshake coming from connections wit Google and Yahoo... i do not see this on my connections but it is being seen on other's connections... there's also a lot of [119:19:1] (http_inspect) LONG HEADER [120:3:1] (http_inspect) NO CONTENT-LENGTH OR TRANSFER-ENCODING IN HTTP RESPONSE [120:8:1] (http_inspect) INVALID CONTENT-LENGTH OR CHUNK SIZE [129:7:1] Limit on number of overlapping TCP packets reached [129:12:1] Consecutive TCP small segments exceeding threshold [129:15:1] Reset outside window on the same connection from those same external sources... how can this be? could it be the result of dropped packets or something else? -- NOTE: No off-list assistance is given without prior approval.
