Hi Lee. My WinPcap version is 2.01.000 (I believe this is the latest). I am passing snort the interface number that corresponds to the ICSHARE interface. Thanks for the -W tip, I hadn't spotted that. Much easier that digging through the registry :). Given that, my thought process is below: Output of snort -W: -*> Snort ! <*- By Martin Roesch (roesch () clark net, www.snort.org) WIN32 Port By Michael Davis (mike () datanerds net, www.datanerds.net/~mike) Interface Device Description ------------------------------------------ 1 PPPMAC (PPP Adapter.) 2 PPPMAC (PPP Adapter.) 3 pptp () 4 PCINT () 5 SpeedTouch () 6 SpeedTouch () 7 ICSHARE () 8 SpeedTouch () 9 SpeedTouch () Output of ipconfig /all: Windows 98 IP Configuration Host Name . . . . . . . . . : macguffin.lotsofbeer.demon.co.uk DNS Servers . . . . . . . . : 192.168.0.8 Node Type . . . . . . . . . : Hybrid NetBIOS Scope ID. . . . . . : IP Routing Enabled. . . . . : Yes WINS Proxy Enabled. . . . . : No NetBIOS Resolution Uses DNS : Yes 0 Ethernet adapter : Description . . . . . . . . : PPP Adapter.

Thus: snort -c snort.conf -l log -i7 leading to: --== Initializing Snort ==-- Initializing Network Interface ICSHARE ERROR: OpenPcap() device ICSHARE open: Error opening adapter Now, am I choosing the wrong adapter to snort, or is there a problem with sniffing ICS

Try "snort -W" for a list of them. Additionally, you need to install the latest WinPcap . I don't remember the URL, but an archive search would easily reveal it. - Lee-----Original Message----- From: Andy Duncan [mailto:andyduncan () motives co uk] Sent: Tuesday, June 05, 2001 9:13 AM To: Snort-Users Maillist (E-mail) Subject: [Snort-users] Win98 Internet Connection Sharing Hi, I have been using snort successfully on Linux for a while now, and this weekend I attempted to add some protection to my windows 98 'firewall' running Internet Connection Sharing (I know, I know, but my USB ADSL modem doesn't work under Linux). I'm not 100% sure of the details here as win98 networking isn't my thing, but the interface that seems to get the external ip is called ICSSHARE. However, starting snort using this interface results in a message along the lines of: Using interface ICSSHARE. Cannot open interface. Snort stops at this point and the machine often freezes. snort command line: snort -c snort.conf -l log\ -i 7 (Apologies for the vagueness, I'm at work atm and doing this from memory) Attaching to any other interface results in either snort exiting or no alerts being logged. Is snorting an ICS interface possible, or am I in a world of hurt? TIA, Andy PS. I've got a FreeBSD ISO on the way which will hopefully make all this academic :) _______________________________________________ Snort-users mailing list Snort-users () lists sourceforge net Go to this URL to change user options or unsubscribe: http://lists.sourceforge.net/lists/listinfo/snort-users Snort-users list archive: http://www.geocrawler.com/redir-sf.php3?list=snort-users_______________________________________________ Snort-users mailing list Snort-users () lists sourceforge net Go to this URL to change user options or unsubscribe: http://lists.sourceforge.net/lists/listinfo/snort-users Snort-users list archive: http://www.geocrawler.com/redir-sf.php3?list=snort-users
