Quite simply, the two are tottaly different, and what you are seeing is expected depending on your rules.

[Note: In the following 'file' means "any way that Snort is configured to log" with that would be a DB, flat file, pcap, or whatever.]

If the rule starts with 'alert' then it will alert to a file and log to a file the packet--But that's in no way the same as the 'log' keyword.

If the rule starts with 'log' then it will log to a file and _not_ alert.

Basically, there are two "buckets"--Alert and Log. When a packet is flagged as an alert, it goes into the Alert bucket. When the alert is done, then that same packet goes into the Log bucket so that the packet is not only alerted on, but logged to <whatever> as well. If the packet is thrown into the Log bucket, then it is simply written to <whatever> without an alert firing.

Does that make more sense?

Cheers!
