Or just install a copy of Etheral and run a packet capture...it will give you the full interface name on a Winblows box :) -----Original Message----- From: snort-users-admin () lists sourceforge net [mailto:snort-users-admin () lists sourceforge net] On Behalf Of Michael Steele Sent: Tuesday, March 22, 2005 12:35 AM To: 'Snort Users Postings' Subject: [SPAM] - RE: [Snort-users] -i switch - Email found in subject You will need to dive into the registry for those settings.

I'm not at my Snort development machine right now to verify that it was committed to the Snort source code, but try putting the whole "Device" string in quotes after the -i. For example, using the interface below... -i "\Device\NPF_{9C7E2353-B2CB-4716-B424-582C30D2C4E2}" would be the same as: -i 1 Chris Reid On Mon, March 21, 2005 3:18 pm, Snort said:The changing of the interfaces is a windows thing... I am not sure how you would hardcode the interface to a particular number. In the Unix world, no matter if you disable or not use an interface, it will always be what it was installed as or what you specify it as in the modules file. In windows, it changes based on if you disable or enable NIC, like you are experiencing now. To defeat the issue, you might have to come up with a script that will look for that NIC device string (found when you do snort -W), grep the interface number and start snort based on that interface. That makes your install a bit smarter so that you install 4 more nics for virtual webserver or pptp, snort will always start on that interface your looking for. Interface Device Description ------------------------------------------- 1 \Device\NPF_{9C7E2353-B2CB-4716-B424-582C30D2C4E2} (Broadcom NetXtreme Gigabi t Ethernet Driver) 2 \Device\NPF_{444422A1-AB79-4CDB-B3C9-FF274A4C6152} (Intel(R) PRO/1000 XT Netwo rk Connection) knowing the above, a script could* look like this eth="Snort.exe -W | grep.exe -i "C6152" | cut.exe -b 1" ^ this will produce a result of "2" Snort.exe -i"$eth" -o -c ../etc/snort.conf Michael Brown -----Original Message----- From: snort-users-admin () lists sourceforge net [mailto:snort-users-admin () lists sourceforge net] On Behalf Of Lee Clemens Posted At: Monday, March 21, 2005 4:26 PM Posted To: Snort Conversation: [Snort-users] -i switch Subject: [Snort-users] -i switch I have seen documentation with using the -i switch followed by a number and with eth0, eth1, etc... However, it seems this is OS dependent. I am using windows and "Snort -W" does not supply the names of the connections (eth0,...). Is there any way I can cause these numbers to remain static or work around this issue some other way? I have tried installing Snort with "-i eth0" but OpenPcap fails to open the device. I am asking this because I disable/enable some network connections on this computer periodically and this disrupts the numbering scheme, causing Snort to be looking at the wrong NIC.
