networking - Microsoft Remote Desktop Bandwidth Usage

I am wondering how much bandwidth in terms of bytes sent/received is consumed by a typical remote desktop session. I need to know this because our ISP enforces a cap on monthly bandwidth usage (i.e. the total amount data in GB that can sent or received in a month). So just wondering like how much KBs or MBs are transferred per hour in an average RDP session.

Answer

With the recent advancements to the Task Manager, incorporating Resource Monitor, you can easily see the bandwidth usage from Terminal Services.

In short, it all depends on the settings you have used and what you're doing in the remote session. More actions require more repaints. Below are two shots I've taken while in an RDP session to a Windows 2008 R2 server.

The first screenshot, only Resource Monitor open (~3.6KBps):

The second, a YouTube video streaming (~951KBps):

Hourly bandwidth consumption at rates like these can vary from ~12M to 3.4G+. Unless you are watching video over RDP, the higher end of the ladder is highly unlikely. For normal activity at 1024x768 resolution with standard settings I'd estimate about ~25M per hour.

Use Google instead of Bing with Windows 10 search

I want to use Google Chrome and Google search instead of Bing when I search in Windows 10. Google Chrome is launched when I click on web, but it's Bing search. (My default search engine on Google and Edge is http://www.google.com ) I haven't found how to configure that. Someone can help me ? Answer There is no way to change the default in Cortana itself but you can redirect it in Chrome. You said that it opens the results in the Chrome browser but it used Bing search right? There's a Chrome extension now that will redirect Bing to Google, DuckDuckGo, or Yahoo , whichever you prefer. More information on that in the second link.

linux - Using an index to make grep faster?

I find myself grepping the same codebase over and over. While it works great, each command takes about 10 seconds, so I am thinking about ways to make it faster. So can grep use some sort of index? I understand an index probably won't help for complicated regexps, but I use mostly very simple patters. Does an indexer exist for this case? EDIT: I know about ctags and the like, but I would like to do full-text search. Answer what about cscope , does this match your shoes? Allows searching code for: all references to a symbol global definitions functions called by a function functions calling a function text string regular expression pattern a file files including a file

How do I transmit a single hexadecimal value serial data in PuTTY using an Alt code?

I am trying to sent a specific hexadecimal value across a serial COM port using PuTTY. Specifically, I want to send the hex codes 9C, B6, FC, and 8B. I have looked up the Alt codes for these and they are 156, 182, 252, and 139 respectively. However, whenever I input the Alt codes, a preceding hex value of C2 is sent before 9C, B6, and 8B so the values that are sent are C2 9C, C2 B6, and C2 8B. The value for FC is changed to C3 FC. Why are these values being placed before the hex value and why is FC being changed altogether? To me, it seems like there is a problem internally converting the Alt code to hex. Is there a way to directly input hex values without using Alt codes in PuTTY? Answer What you're seeing is just ordinary text character set conversion. As far as PuTTY is concerned, you are typing (and reading) text , not raw binary data, therefore it has to convert the text to bytes in whatever configured character set before sending it over the wire. In other words, when y...
