问题 I'm receiving rtp packets with JPEG payload with VLC. When I mannually setup the type to 26 (JPEG), vlc doesn't try open the stream; if I define it as 96, vlc opens it and displays it wrong - that is due to malformed encoding. To find out the correct encoding, i.e to find out what values of packet headers are correct, i want to compare the rtp packets with working example. Surprisingly, example uses payload type 96 instead of 26. I user wireshark to observe the headres; if works fine with

问题 I want to create a small TCP server that takes incoming TCP connections from a device that is hooked up via Ethernet to my computer. The physical port for that has the IP 192.168.1.100 statically assigned to it. The scripts I use as a client and server are listed at the bottom. The setup works if I want to send messages between the python scripts. However, I am unable to receive anything from the external device (screenshot from Wireshark capture below). From what I have read I can define an

问题 When I enter either this URI to call a REST method on my running Web API app: http://SHANNON2:21608/api/inventory/sendXML/duckbill/platypus/someFileName // using Hostname of local machine --or this one: http://192.168.125.50:21608/api/inventory/sendXML/duckbill/platypus/someFileName // using IP Address of local machine ...in Postman (using HttpPost, and attaching an xml file) and run it, on examining it in Fiddler 2, I see this error in Fiddler's Inspectors.WebView pane: Bad Request - Invalid

问题 I am on Linux platform with PostgreSQL 5.5. I am trying to monitor all traffic related to PostgreSQL between Master and Slave. To that end, I used Wireshark to monitor the traffic. Then, I started PostgreSQL and ran three queries (Create table Hello, Create table Bye & inserted an image to PostgreSQL database). During queries, I ran Wireshark on Master just to capture the traffic between Master and Slave. But there is one problems with PostgreSQL traffic captured using Wireshark. All the

问题 I want to monitor data size transferred into and out of my database. I'm using a Java client application & Firebird v2.5 database. Both are deployed locally on one machine. It turns out that Firebird does not provide any monitoring variable like "Bytes_received" or "Bytes_sent" that are available in MySQL. as discussed in Is there any way to monitor the size of data transfer In/Out of database So I set up some tools to capture the local traffic and analyse it. WireShark - to analyse the

问题 I am writing a Wireshark plugin to dissect a protocol that places multiple application-level packets in a single UDP frame. There is no enclosing protocol that indicates how many packets there are in the frame. So essentially, the payload coming down the wire will look like this: uint64 sequence1 uint64 data1 uint8 flags1 uint64 sequence2 uint64 data2 uint8 flags2 : : : uint64 sequence_n uint64 data_n uint8 flags_n In my server code that actually processes this information, I simply loop

问题 In order to learn how other applications connect to internet services I would like to monitor the traffic via Wireshark on my Linux PC. I know there are Wireshark tools for Android, but these require that the phone is rooted which mine isn't. I have read several places that if the phone and the pc running wireshark use the same wifi connection, it is possible to monitor the traffic from Wireshark on the pc if it is running in promiscous mode. I have tried that but I can't see any traffic

问题 I am trying to analyse a file containing packets captured using tcpdump. I first want to categorize the packets into flows using 5-tuple. Then I need to get the size and inter-arrival time of each packet in each flow. I tried Conversation list in wireshark but it gives only the number of packets in the flow not information about each packet in the flow. A suggestion for any code (c++ or shell script) that can do the job? Thank you 回答1: UmNyobe, If you haven't heard of Scapy yet I beleive what

问题 I am using Pyshark to parse Wireshark sniffer log, and I used exported Json format file (based on pcapny file) to find field names when use 'get_field_value' function to retrieve field value. For example, in order to get BSSID value: In Json format file, this info is displayed as "wlan.bssid": "11:22:33:44:55:66" Then I could use: value = packet['wlan'].get_field_value('bssid') Result is expected: value == '11:22:33:44:55:66' For this case, it is working fine. But I encounter an issue with
