2/26 Hello, I am providing the result of what was asked of me to help troubleshoot the daemon problem. The daemon runs if INTERFACE=any. root@Gateway snort]# tail -f /var/log/messages ######## I ran snortd with INTERFACE=any ##################################### Feb 26 11:08:45 Gateway snort: ------------------------------------------------------------------------------- Feb 26 11:08:45 Gateway snort: Rule application order: Feb 26 11:08:45 Gateway snort: ->activation Feb 26 11:08:45 Gateway snort: ->dynamic Feb 26 11:08:45 Gateway snort: ->alert Feb 26 11:08:45 Gateway snort: ->pass Feb 26 11:08:45 Gateway snort: ->log Feb 26 11:08:45 Gateway snort: Feb 26 11:08:45 Gateway snort: Log directory = /var/log/snort Feb 26 11:08:45 Gateway snort: Snort initialization completed successfully (pid=7339) Feb 26 15:22:03 Gateway snort: Final Flow Statistics Feb 26 15:22:03 Gateway snort: Snort exiting Feb 26 15:22:03 Gateway snortd: snort shutdown succeeded ######## I ran snortd with INTERFACE=3Dany ################################### Feb 26 15:22:07 Gateway modprobe: modprobe: Can't locate module 3Dany Feb 26 15:22:07 Gateway snort: FATAL ERROR: OpenPcap() device 3Dany open: ^Iioctl: No such device Feb 26 15:22:07 Gateway snortd: snort startup failed I feel that in some machines snort is not listening on all interfaces even when I ran with INTERFACE=any. I got positive results in one of them.

2/24 Hello, Thanks to Mr. Maria Lopez Hernandez for responding especially for clearly pointing the change to me. I am not well versed in scripts. I did as was advised. When I try to start the service it fails. Is there anything more that I should do to get the script running on all three interfaces? Thank you.

You have to send to the list the error that snort gives to you. If there's an error shown when the script runs and also you can do a "tail -f /var/log/messages" and then run the script to see what snort says when it tries to start. If you post that information we maybe can help you further. Regards. --=20

There is a parameter INTERFACE= , in the file. What value should I give if I want snort to sniff all interfaces? By default, it takes only eth0 and does not seem to change interface even if I specify eth1, or eth2. Any help is welcome.

There is a parameter INTERFACE=3D , in the file. What value should I give if I want snort to sniff all interfaces?Just use: INTERFACE=3Dany But you have to change the script. What it's wrong it's the script you are using. It specifies the variable INTERFACE but it doesn't use it later to launch snort, so it won't work. Change the line: daemon /usr/local/bin/snort -u snort -g snort -d -D \ -c /etc/snort/snort.conf to: daemon /usr/local/bin/snort -u snort -g snort -d -i $INTERFACE -D \ -c /etc/snort/snort.conf and it will work.By default, it takes only eth0 and does not seem to change interface even if I specify eth1, or eth2. =20 Any help is welcome. =20 Thank youRegards. --=20 Jose Maria Lopez Hernandez Director Tecnico de bgSEC jkerouac () bgsec com bgSEC Seguridad y Consultoria de Sistemas Informaticos http://www.bgsec.com
