Anyway: Throughput problems are more often related to packet loss than to windows size updates, unless the receive window drops to far (near 0 or to 0). In that case it will obviously have an effect on throughput.
Another thing which surprises me is that your machine sends a DNS request, asking for an IP of ctldl.windowsupdate.com, but doesn't wait for a response for a reasonable amount of time, as when the answer arrives in less than two milliseconds, it is already rejected with icmp "destination port unreachable". Normally, DNS responses coming within seconds are still awaited and accepted.
I'm having the same problem now after upgrading wireshark to the latest version yesterday. It was working before that, and as part of the upgrade process I didn't upgrade WinPCAP (already had the latest version). I think there's something else going on here.
Copying files from the server to the client just via windows copy/unc. I ran the capture on a transparent ASA at the Server end which is inline to the traffic flow. Issues I have are that the transfer just stalls, seems to try again and the eventually just stops with a general windows error, cannot copy blah blah. It seems to occur if I copy anything more than a few 100MB. I see references to mturoute and iperf in my captures which I have no idea where they are coming from. Neither are running on the server / client. Is there any indication as to why the capture is failing and also to why mturoute and iperf are showing within the SMB messages? The buffer on the ASA wasn't big enough so had to run circular buffer and managed to capture the moment the copy failed. This is across a DMVPN also. Capture attached =0
Looking at the trace I'd say your description of the environment is incorrect. The windows client is at 10.49.3.61 and the trace was taken close(r) to the client. The server is at 172.25.225.10 and behind a WAN VPN connection through a riverbed. The initial RTT towards the server is 166 ms The direction of the traffic is from client to server -> 445 The riverbed is offering a window_scale factor of 4 The stalled session is due to a zero window offering of the riverbed device, obviously it is not getting the data forwarded fast enough over the WAN (maybe packet loss?)
I had the same issue. I was using it for the first time. As in the above answer by Ron Maupin, I didn't select an interface. When you start wireshark you see in the middle of the window a scrollable list of interfaces eth0, wlan0 etc. Choose whichever you want to monitor and click on start (capture). Or there is wheel button - configure capture - which will pop up a window where you can choose the interface and press start.
Hi, Nice post. I can see the frequency (channel) is not visible in wireshark. When you sniffer with multiple adapters its nice to know if they are all working correct. Any idea why the frequency is set to 0?
Lets say i have already converted a wireshark pcap file to a windows text file, so do i need to "format" the data from the wireshark txt file to log data if i want to monitor the wireshark text data using Splunk??? I went to the Splunk manager > data inputs > Add data > Files and Directories > Data Preview > Add New. Under Add new section i selected "Continuously index data from a file or directory this Splunk instance can access" then i entered the path of the wireshark windows txt file and i saved the settings.
Every raw data for each log event shown for the wireshark txt file source doesn't seem right to me. I would like to know if there is any way to display the wireshark capture data in the windows txt file as log events correctly as in getting logs out of Wireshark pcap files????
I'm assuming the physical nic connected ot he switch port mirror is connected to a unique vswitch in esx, then you give the vm a nic in this vswitch. Enable promiscuous mode and set wireshark to capture on that nic.

Wireshark has the ability to use SSLKEYLOGFILE to decrypt https traffic. This file is a feature provided by the web browser. When a Web Browser is configured to create and use this file all of the encryption keys created for that session are logged. This allows Wireshark to decrypt the traffic. If you supply SSLKEYLOGFILE and a pcap file that were taken at the same time, wireshark will show you all of the web traffic.
The CA plugin dissects all CA header fields, and the channel name is alsotracked along the virtual circuit. Those fields and channel names canbe specified in the filter expression to search the packets ofparticular interest. Slightly more detailed description is available.Please send your bug reports and comments to Kazuro.Furukawa at KEK.jp. Screen shotTypical screen shot. Packets are captured for EPICS CA protocol with a capture filter of (port 5064 or port 5065). Then those event_add commands/responses are displayed with a display filter of (ca.cmd == CA_PROT_EVENT_ADD). The corresponding channel name is tracked and displayed.V1.0.1, production version with Wireshark 0.99.8 or 0.99.7by Klemen and Anze Zagar at CosyLabCA plug-in source for wiresharkwireshark-ca-1.0.1.tar.gzPatch against wireshark-0.99.8 and -0.99.7 for CA plug-inwireshark-0.99.8-ca-1.0.1.patch
