I've answered my own question:

    When you run snort without any options it defaults to running in
promiscuous mode. When you specify the -D option it doesn't. Evidently the
network I'm on isn't as 'switched' as it should be.

Hello,

    I've got Snort running and it's logging away quite happily. There is
something that makes me scratch my head though. How come it's catching stuff
thats not destined for my machine?

Here's a scan.log entry:

12/09-16:33:08.677905  ICMP src: 212.4.208.191 dst: 213.239.42.97 type: 8
code: 0 tgts: 8 event_id: 204

The dst IP isn't mine! Does Snort set your ethernet card to be
'promiscuous'? Even so I'm on a swicthed network. I'ts not just portscan
that does it it ops up in the normal log too. Does anybody know what causes
this or am I reading the logs incorrectly??

Thanks.

Regards, John.
