Also, you

Unable to connect to OnVif enabled camera using C#

由 一世执手 提交于 2020-01-02 07:36:33
问题 I am working with IPCams for the first time and I am trying to connect to an OnVif camera. I have looked on various forums and stack overflow and I have come up with the following code.I know the code doesn't do anything useful but it is just a proof of concept for now. It finds all 4 cameras on my network and then I am manually connecting to one of them to pull back some information such as GetServices . I get a 400 bad response error at this stage. I have looked at the traffic back and

How can I determine which packet in Wireshark corresponds to what I sent via Postman?

问题 I'm trying to figure out why REST calls sent from my handheld device (Windows CE / Compact Framework) are not making it to my server app (regular, full-fledged .NET app running on my PC). The handheld device and the PC are connected - I know that because I can see the handheld device in the PC's Windows Explorer, Windows Mobile Device Center verifies the connection between the two is valid, etc. I reach the breakpoint on my server app running on my PC when I pass the same REST call via

问题 I know how to do it manually (by looking at the hex dump). How can I obtain the same automatically? Do I have to use the APIs? I have both wireshark and Microsoft network monitor. 回答1: This can be achieved simply with a Lua dissector that adds an HTTP header field to the packet tree, allowing you to filter for it, as shown in this screenshot: Copy this Lua script into your plugins directory (e.g., ${WIRESHARK_HOME}/plugins/1.4.6/http_extra.lua ), and restart Wireshark (if already running). do

Using libwireshark to get Wireshark functionality programmatically

由 纵饮孤独 提交于 2020-01-01 04:45:10
问题 If I want to write a script that uses Wireshark's functionality, I use tshark. I hear there is also a libwireshark that can be used when writing a program in C but, for the life of me, I can't find any documentation for it! I tried isolating the library code in the wireshark source tree, but it seems the code is not very well organized and such isolation does not exist (either that, or I have failed to find it). I have two questions: Am I right in thinking that libwireshark can indeed be used

Plot RTT histogram using wireshark or other tool

由 不问归期 提交于 2020-01-01 03:20:55
问题 I have a little office network and I'm experiencing a huge internet link latency. We have a simple network topology: a computer configured as router running ubuntu server 10.10, 2 network cards (one to internet link, other to office network) and a switch connecting 20 computers. I have a huge tcpdump log collected at the router and I would like to plot a histogram with the RTT time of all TCP streams to try to find out the best solution to this latency problem. So, could somebody tell me how

问题 enter image description hereenter image description hereenter image description hereI got some csv files. The file names are as filename1.in.csv and filename1.out.csv , filename2.in.csv and filename2.out.csv. These files are in folders and sub folders. I'm trying to calculate some statistical values of .in.csv files separately and .out.csv files separately. But at the end all these needs to get written into one csv file (known as OutputFile in my code) row by row with headings. Each row gets

How to decrypt service to service SSL traffic using wireshark?

由 北战南征 提交于 2019-12-31 01:52:08
问题 Using fiddler causes some of the applications to stop working correctly on my windows machine. I want to use wireshark to decrypt all ssl traffic between my tomcat and a remote server. All traffic is https. I was able to set environment variable SSLKEYLOGFILE and decrypt all SSL traffic generated by the browser. But that does not work for service to service calls. Having access to the private key of tomcat does not help anymore because of something called forward secrecy (I don't know much

用Python开发MySQL增强半同步BinlogServer（T3实战篇）

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 导读 ： 作者：曾永伟，知数堂10期学员，多年JAVA物流行业开发管理经验和PHP/Python跨境电商开发管理经验，对数据库系统情有独钟，善于运用SQL编程简化业务逻辑，去年开始正式从业MySQL DBA, 专注于DB系统自动化运维、MySQL云上实践。 一、概述 通过前两篇的基础，我们已经能够深入理解二进制与MySQL的协议关系了，并且能够结合自己的需求，从官方文档找出相应的文档来实现自己的功能，希望大家鱼渔双收。 需要特别强调的是，通过文中的例子和思路，要学会把一个复杂的问题进行以拆分，细化成一个一个的小任务后再逐个去实现，特别是对接触编码不久的同学特别重要，从Hello World模式开始编码在任何阶段都适用（它是一个最小无依赖的可执行单元），因为它能排除众多干扰项，让你可以专注自己的小目标进行编码和测试。 目前我们已经能够用Socket和MySQL进行基本通信了，也能够处理Binlog文件的Event了，离我们的BinlogServer仅有一步之遥了，这一步就是通过Socket读取Binlog Event并保存到本地。 这一篇之所以叫实战篇，就是希望你不要停在只看不练的阶段，这里再重提一下基础篇的要点： 只有会认真看文档的DBA才是好DBA，只会认真看代码的Engineer,一定不是好Engineer
