FYI - Here is the full Wireshark packet of the summarized packet that I noted above. Do you see anything in there that would allow me to search for the ZeroWindowProbeAck info?
Hi, New to Wireshark and am looking to filter traffic to/from a partial IP address, 50.xxx.xxx.152. What is the correct syntax? ip.host matches "\.152$" gets me the last octet but need to filter on the first as well.
I use Wireshark on Ubuntu 22.04 . First of all, it was not exactly clear which colour was meant to select the Yes or No answer on the configuration whether a non-superuser should be able to capture packets of network interfaces. I thought it was the red background when I selected a button. When I selected that non-superusers should be allowed, I haven't seen the hardware network interfaces ...
I made a plugin for Wireshark and now with the new version 4.4.2 it is not working anymore. It seems like something with Lua has changed, but I can't find the problem. With the old version 4.2, everything worked and it showed the hex stream correctly. However, in version 4.4.2, the plugin no longer parses the data as expected.
Comments The captured traffic isn't in the readable format of the Wireshark. I have just the header of the captured traffic as the sample above. How can I filter out TCP retransmission myself using the header information? Zahra ( 2017-11-17 16:40:14 +0000 ) edit
This is clearly visible, several times, in blue on the Wireshark chart (Statistics - TCP Stream Graphs - Window Scaling). An excellent presentation about Congestion Avoidance algorithms was made by Vladimir Gerasimov at SharkFest 2019 (@Packet_vlad). He did a lot of valuable research and preparation.
I went into Wireshark and on the home screen the wifi activity is shown. When i go to Capture>Options, the checkbox under the Monitor Mode column does not allow me to check it. I don't know why it's doing this? If I double click the wifi interface in question it starts capturing, but I haven't seen any other traffic other than my own.
Wireshark on the other hand captures the network traffic as it happens. So it can show you the TCP packets involved and therefore the port numbers involved in these connections. Find the TCP packets with the correct IP addresses (yours and bing's) and then look at the TCP layer details.
Using Wireshark 4.4.1 which includes Npcap version 1.79. Npcap installed with the option “Support raw 802.11 traffic (and monitor) for wireless adapters.” Wlanhelper has been used to place the wireless adapter into monitor mode, and the Monitor Mode checkbox in Wireshark for the adapter has been checked.
