Re: Some alerts not logging packet data

[James Lay <jlay () slave-tothe-box net>]

Haven't received much on this, so I thought I'd try and add some more info.
Here's the hit:
11/27-10:52:18.548118  [**] [138:2:1] SENSITIVE-DATA Credit Card Numbers
[**] [Classification: Sensitive Data was Transmitted Across the Network]
[Priority: 2] {TCP} INT_IP:51126 -> EX_IP:25


u2spewfoo output:
(Event)
        sensor id: 0    event id: 1312  event second: 1322416338
event microsecond: 548118
        sig id: 2       gen id: 138     revision: 1      classification: 35

        src port: 51126 dest port: 25   protocol: 6     impact_flag: 0

There's no information in the tcpdump.log file.

Not sure this matters or not, but here is smtp relevant entries:

Does anyone have any hints or ideas?  Thank you.
