Wireshark does not show all packets

["Panagiotis Georgopoulos" <panos () comp lancs ac uk>]

Hello all,

 

                I am using Wireshark to debug the packets that are received
and sent to my wireless interface. I am also using hostapd to create a
secure Access Point for other machines to connect to. Some weeks ago I was
using madwifi drivers for my wireless card, however I found them to be too
buggy and thus I swapped to ath5k and also upgraded my hostapd to version
0.7.2.

 

These two changes make a difference when I run hostapd that creates the
access point. Instead of having my wlan0 as the only wireless interface
handler, there is another one being created, called mon.wlan0, that creates
the mess. Some packets seem to be sent from wlan0 and others from mon.wlan0
and this makes it very difficult to debug. Therefore I decided to use the
pseudo-all interface in Wireshark (version 1.2.1) to see all the packets in
one instance of Wireshark. However it seems that some packets are not being
displayed  in Wireshark at all!!! I am sure about this because I see replies
coming in from another machine that were originated from mine, but  I never
see my initial request in Wireshark. It seems that some packets that I sent
from that interface are not being shown in Wireshark.

 

Does anyone have any idea why this happens and how can I solve this problem?

 

                Thanks a lot in advance,

                Panos
