[WinPcap-users] "priority" of capture driver and port filtering problem

[Cefur]

 

Well I was wondering could it be that capturing driver "priority" is too low? Well I know it was already talked about ... but I didn't find any good answer. What I am asking is, can this "priority" of the driver be set any higher? 

 

Second question:

How can I pcap_open_dead with pcap_open (for example I would like just to send packets and not capture it from an adapter)?

 

Third question:

How can I set filter to capture only on ports higher then 139, because something like "port > 139" doesn't work?

 

Thx.

First question: Like a lot of you I have made a bridge with WinPCap and now I am playing with it. So I made a little test. When the "bridge" computer is not under heavy load the latency of the bridge is not so big (it can be tolerated). But when this computer is 100% utilized (under heavy load) then an erratic behavior happens. For a couple of seconds the latency is normal then sky rockets (probably a lot of packets is lost - I didn't checked yet) and then again few seconds normal ... etc. I set the priority of the program to critical but that didn't help.   settings: setmintocopy = 0 (for low latency)
