I'm running snort on a Red Hat 9 with mysql db and ACID.
All was working  fine but at a certain point, I don't know the reason, alerts stop to be logged on db and obviously to be displayed through ACID.

I try to see if packets was arriving to the nic using tcpdump and it works.
Now the strange thing: if I run simultaneously snort (as a daemon) and tcpdump (by command line) on the same interface, alerts are logged again in the db and displayed through ACID.

I thought that some how the nic is not put in promiscuous mode when snort starts, so I tried to set it manually (ifconfig eth01 promisc) but sill alerts are not displayed without tcpdump running.

Anyone has a suggestion for me?

Thanks for your help
