Ok, actually I've never tried it. There's probably going to be some some conflicts/collisions that you can't or, hopefully, can overcome. On Tue, 2 Jan 2007 15:14:14 -0500, "Small, James" <[EMAIL PROTECTED]> said: > Hans, > > That's an interesting idea. I just tried it under XP SP2 (two laptops

[Wireshark-users] VoIP Calls - Enhancement Request

2007-01-02 Thread Keith French
VoIP calls is excellent for H.323 calls. However, is there any chance that the start & end times could reflect the current settings in the main Wireshark display for date & time. It currently only displays based on seconds since the beginning of the capture. It would be very useful to be able t

Hans, That's an interesting idea. I just tried it under XP SP2 (two laptops on same AP, same SSID/channel). However, even after disabling gratuitous ARPs, I could not get both laptops to associate to the same SSID on the same AP when I set the second monitoring laptop to have the same MAC (tried

Maybe you could change the MAC-address of the Wireless card (or bridge?) to the MAC-address of the gateway in the network? That way your NIC will accept all traffic going to and from the gateway (and you because you have the same MAC-address). Because the MAC-adress in those packets is the same as

Hi, what do you mean with "... the program does not recognize any VoIP calls"? You don't see any RTP packets? Note that since RTP is an application layer protocol with dynamic port assignments, it is not by default decoded in Wireshark, unless ... - the capture also contains the signalling traf

Yep--that's it. Thanks Guy. Also, just for the record, I tried capturing under WinPcap under XP, SP2 both using the Microsoft Bridge and just using my wireless adapter in non-promiscuous mode (Intel Pro Wireless 2200BG built-in to a Dell Latitude D610). My particular wireless card will only capt
