The reason you're seeing nothing in the interface list is also a WinPcap problem. In previous versions of WinPcap there is a 1K buffer, which overflows if you have many interfaces (ie. 10+). This has been replaced with an 8K buffer in more recent versions of WinPcap. The current snort distribution should already be linking against the newer WinPcap libraries, which should resolve this problem. Try obtaining a more recent build of snort.

I've done a little digging and from what I can see this appears to be a WinPcap problem, I tried windump -D and I get the same error, so it's not snort specific. Also one thing I didn't mention previously was that my snort -W shows what I think is nothing. There are 4 nics in my machine
and
all I see is this: C:\Snort>snort -W -*> Snort! <*- Version 1.8.7-MySQL-WIN32 (Build 121) By Martin Roesch (roesch () sourcefire com, www.snort.org) 1.7-WIN32 Port By Michael Davis (mike () datanerds net, www.datanerds.net/~mike) 1.8-WIN32 Port By Chris Reid (chris.reid () codecraftconsultants com) 1.8-WIN32 Compiled By Michael Steele (michaels () silicondefense com, www.siliconde fense.com) (based on code from 1.7 port) Interface Device Description ------------------------------------------- 1 C:\Snort> For some reason I think this interface 1 is a loopback.

is
in progress. Fatal Error, Quitting.." The FAQ says this can be due to an old incompatible, or uninstalled
version
of WinPcap. I'm using 2.3 and the install appears to be running successfully. Is there any way I can check to make sure it is, or is this already a known issue? Thanks, JonM
