Correction: My poor choice of wording...sorry.
Ethereal was displaying and capturing forwarding/broadcast packets
discovered on the WLAN but not 802.11 protocol-type specific traffic. That
is, we did not see any "802.11x" in the protocol column.

What do you mean by "cannot decode"?  In the context of Ethereal, "cannot
decode" means that the packets are captured correctly, but are not displayed
correctly in the packet detail window.  It does *not* mean that you can't
even capture the packets; that's "cannot capture".

Turning off promiscuous mode is a workaround for a "cannot capture" problem:

    http://www.ethereal.com/faq.html#q5.37

It's not a workaround for a "cannot decode" problem.

Different operating system?  Windows drivers for wireless cards are
*really* not very helpful to applications that try to capture network
traffic; Linux and BSD drivers do a better job.

Please note that you probably have to configure Ethereal to handle ANSI
instead of ITU.

Edit/Preferences.../Protocols/MTP3/MTP3 Standard

I don't know if that will solve your problems, but at least it seems that
packet-sccp.c is using the mtp3_standard setting from MTP3 dissector.

Hi 
Is it normal for PC's mainly Winxp to do arp requests to the next ip in the
address range eg. 192.168.10.15 will request mac adress for 192.168.10.16
even if it doesn't exist.

Thanks Phil

To: ethereal-users@xxxxxxxxxxxx
Message-ID: <40D2ED46.6020905@xxxxxx>
Content-Type: text/plain; charset=ISO-8859-1; format=flowed

Hi all,

I have installed ethreal 0.10.4 in a WinNT machine  with winpcap-3.1.beta 3.
I am using  tethereal -i "ifname" -z io,stat,1,ip.addr==192.168.0.1 -a
duration:5 Although capturing of packets is ok -z doesn't provide the
correct statistics. In the table produced the column #0 name is null instead
of ip.addr==192.168.0.1. I believe that capturing is ok because when I
capture to a file and process the file with tethereal on linux, or  on
windows 2000 everything is fine. The same command works perfectly for me on
linux and windows 2000.

Furthermore on Windows NT tethereal gives me: adns: GetNetworkParams()
failed with error [50] ERROR_NOT_SUPPORTED

Any help on solving this problem would be appreciated,
thanks,
Ioannis-
