I know how to create custom columns however I am having a hard time generating the filter I need in order to determine if a network packet is Open/WEP/WPA protected. Wireshark has this capability, I have seen it in the WLAN Statistics tool.
I would assume it would be some sort of wlan_mgt.rsn. However I have only got wlan.rsn.akms.type to display 'PSK'. I am close to what I want just not exactly what I want.
Try wlan_mgt.rsn.akms.type.

Are there any Wireshark gurus?
I am debugging an issue on my home Zigbee network. I have a sniffer dongle and I can catch all the packets transmitted. Since my network has ~40 devices, the air is quite cluttered with packets I am not really interested in. I am looking for a ways to filter uninteresting messages
Questions:
Is there a way to filter out messages related to IEEE protocol (various Data Requests, and Acks), while leaving only upper layer messages (Zigbee, Zigbee HA)?
Is there a way to assign human readable labels for the devices on the network? e.g. 'Coordinator' instead of 0x0000, or 'Light Switch' instead of '0xc83a'?
I would propose making your own filters (whoah, relax, we are not animals, we do this the smart way) ... go to Statistics > Protocol Hierarchy, the panel should show you all the traffic by protocols. Then just identify which protocols you do not want to see, mark them (one by one), right-click and Prepare as Filter > ...and not Selected (to prepare a filter to exclude the highlighted protocol). Sadly wireshark does not allow you to select multiple protocols to exclude at once. After this simply save your filter and reuse it as much as you like
What you are trying to do is Name resolution. This is done via configuration files, more specifically ethers and hosts
I need to capture https traffic. In particular the client hello messages. But I need to analyse their content. I learned about wireshark. How can I to extract the data from the packet content? i.e. the client hellp content? The tool displays the packets. If I click on them, I see more information but how to aggregate them. i.e. I need the field length (as shown in the picture) for all client hello messages?
Are there any tools to do so? Or can Wireshark do this function?
EDIT: In the picture, this is a client hello message. I need some data like the length. How to extract this and aggregate it for large traffic?
Image for illustration
You can do this with wireshark with a filter of "ssl.handshake.type == 1". This will give you all Client Hello packets. From there you can manually inspect the client hello message or you can even make any field in the client hello message a column in Wireshark. To do this, drill-down into one of the packets to the field you want to see. Right-click that field and select "Apply as Column".
If you want to do this programmatically, you could also write a program that uses libpcap to capture packets. This is more work though since you would have to manually dissect the packets yourself.
We have a group of users who need to see the payloads of packets in wireshark captures. I'm looking for a way to remind them users that the data contained within may not represent the exact frames on the wire (because the capture will have been pre-processed by the time they get it to remove, e.g. security-sensitive IP addresses). A hook in the capture file that triggered a popup with a short message would be perfect. Is there anyway to do this, short of wrapping Wireshark with another binary (which would be trivially bypass-able anyway)?
I've searched in the wireshark lists but come up empty.
The only thing you could do would be to have the pre-processing program write out the file in pcapng format and add a comment to the initial Section Header Block giving that warning. That won't produce a popup - but, then, not all the capture file reading programs in the Wireshark suite are GUI programs that could produce a popup.
This is a little off the beaten path. I've got a DLink DWL-G520 card I'm using under OpenBSD and it works fine. What I want to do is be able to access the radio part of it. Why? I want to use it in a radio telescope. It's a 2.4 GHz receiver with an external antenna connector. I want to connect some coax, some amplifiers, and an old TV dish and point the dish at the sky. It has an RSSI signal and variable RF gain (which it adjusts, from what I can find) so all I'd need to do is record those over time while pointed at a certain spot in the sky. I don't need to control the frequency really since most natural events are broadband.
I'm poking through the OpenBSD ath driver following nested structs but I don't want any of the normal network stuff, which is most of what the driver does. dmesg identifies it as an AR5212 which according to the Atheros PDF is always paired with an AR2112 radio. Is there any easier way than wading through PCI stuff to see what my options are? I need to turn the transmitter off so it doesn't fry my amps too. Trying to find low level documentation is about impossible from what I've seen. Ultimately I'd like to have this work with other WiFi cards too, but I'll start with this one. I've got a Cistron with an external antenna connector also.

sorry for this little bit strange title, didn't found a better one..
I've got the following situation:
I have a PC with an RFID reader connected via USB.
I now need a program which pops up when ab transponder was scanned the the RFID reader and shows the scanned value. (The reader just simulates keystrokes)
Problem: the value of the transponder is something like 0001230431, and I can't change it. (To prefix a hotkey combination or so)
So I have thought about using a global keyboard hook, check if three zeros where typed in, capture rest of data and when the 10 digits are complete, call the application through an automation object and show the number.
But I'm not very exalted about using a global keyboard hook. Many AV programs don't like them very much, they are not so easy to handle with Delphi and I guess that's not very resource-friendly for such a little task...
So I'm looking for an alternative solution...maybe somebody has an idea?
Big thx!
ben, you can use the RegisterRawInputDevices and GetRawInputData functions.
first you must use the RegisterRawInputDevices function to register the input device to monitor and then you can retrieves the data from the input device using the GetRawInputData function.
Check theses functions too
GetRawInputDeviceList retrieves the list of input devices attached to the system.
GetRawInputDeviceInfo retrieves information on a device.
Why not make sure the Delphi app with a text edit control has focus before the scan is done? Then the keystrokes will go straight into your Delphi app.
