In the default setup, if you log to binary it /will not/ generate the ascii mode, however, maku says that the log files being produced are snort.log.###.. This is indicative of binary logging mode.

Because you are using the -b option (binary logging) it is logging into pcap format. Remove the -b to generate an alert file. However, -b is much more useful if you are familiar with Tcpdump or ethereal. Joel
No, that is not correct. The -b (binary logging) option has nothing to do with an alert file being generated. I am not sure why the output facilities are so misunderstood, but here again is an explanation. Snort has two output facilities: alert and log. The default plugin for the alert facility is ALERT_FULL and the default log facility is LOG_ASCII. ALERT_FULL is your std alert output to the /var/log/alert file, while LOG_ASCII writes packet data in ascii format to directories and files based on ip address/protos/ports/etc. The -b option changes the default behavior of the log facility only (to LOG_PCAP).

[snort.conf] output database: log, mysql, and i run with this command... snort -qbID -i eth0 -c /etc/snort/snort.conf -u snort -g snort m 007 then i cd to /var/log/snort/ what i'm confused is theres no alerts file here but except of snort.log.smething so i tail messages log in /var/log/ , yes the snort can see packets going through.... but why it not generates the alerts file like in the 1st box...? can anyone help me out....
Sounds like you may have your database output plugin set to use the alert facility (output database: alert VERSUS output database: log). I'd double check that.
