RE: Problem: Win32 v2.4.3 does not start as a Service

["Michael Steele" <michaels () winsnort com>]

This is a bug, and hopefully it will be sorted out between the Snort and
Pcap developers and a final solution developed.

Kindest regards,

Just wanted to throw this out there...

I recently ran into this same problem on an XP box with WinPCap 3.1 and
Snort 2.4.3, adding the dependencies to the registry solved it right
away....thanks again to those involved!

Perhaps this should be noted in the manual or somewhere, if it hasn't been
added already?

Gianluca,

I see now from the winpcap archives this issue is related to changes
that were made to winpcap between beta 4 and the official v3.1 release.
I also see the issue resulted from someone electing to use the Microsoft
NetMon COM component from within winpcap, and the NetMon component is
primarily intended to capture packets from dialup adapters.

I've read your postings relative to editing the registry to add a startup
dependency, but I don't understand why those of us that don't ever use a
dialup adapter are required to be "dependent" on that component.

Can you help us understand why that dependency became manditory?

Would it be appropriate for the snort win32 distribution to add the registry
entry during the snort installation, ask the winpcap folks to release v3.1.1
with the registry change in it, stay with v3.0 in snort documentation and
recommendations, or, is there another "fix" to this service startup problem?

For those that are actually following this thread, the suggested registry 
changes are:
1. Open the registry with regedit.exe
2. go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services and locate the

Snort service (it should probably be  named "Snort" something)
3. right click on the snort key name, and choose New->Multi-string value
4. name the new key "DependOnService" (be careful to the spelling and the 
capital letters).
5. double click on the newly created key, and add the following names (one 
per line):
    NM
    NPF
    Be careful *not* to put any space before/after each name
