The actual file in the repository you want is called hosts. Those paying attention might notice similarities between blocking content using the Hosts file and the block-lists used by browser-based ad blockers such as AdBlock Plus and uBlock Origin. Looking for something? Written by Douglas Crawford. How to edit your hosts file Windows Search for Notepad, right-click, and Run as administrator. Under the last enter: 0. Advertisement banners e. These ads can sometime contain malware known as malvertising where malicious code is injected into legitimate online advertising networks.
As a way to mitigate against potential malware infection from ads, known addresses of ad servers can be used to block them from delivering potentially malicious content to your company's computers as your staff visits various websites.
This is accomplished by associating ad server names to the loopback address of Special Note: new Windows 10 users This was done to resolve a slowdown issue that occurs with the change Microsoft made in the "TCP loopback interface" in Win8.
This change in the prefix should not affect everyday users. You can use the "Replace" function in Notepad to convert the entries, or either of these freeware utilities see below has an option for converting the entries from "0. This download includes a simple batch file mvps. For more information please see the Windows version that applies to you When you run the mvps. Once updated you should see another prompt that the task was completed. Allow the change Microsoft has done it again If you upgraded recently to Windows 10 version , most likely you will be unable to make any changes to the DNS Client, as it is grayed out.
Then to make things even worse That's just ignorant. Nano is a mature program that does what the users want, and what vi cannot. The fact it's not core is either bigotry, or just simple numbers. In places where nano isn't available, you can get it. For the record, I hate vi with a passion that cannot be described in the human language. Been around for decades and still haven't learned it, and administrate such machines daily. My lack of vi skills is wholly intended, as I availed myself of the repos and installed nano.
Just as it was designed to do. Perhaps we nano users are just the new Luddites, but I don't need to remember 32 trillion commands just to type normally. Insta-fail, and about the weirdest thing I've seen. Most of the time I don't complain, because there were others like me and we just use nano instead of saying that all vi users are idiots that have no business administrating Linux machines.
Lastly, for the record, it's a bad idea from a security perspective to update it nightly as suggested, in ROOT no less! Doing such a thing nightly just makes DNS poisoining your network and machine much easier. Also, automatically appending files from your home directory to your hosts file is a big security concern, but I'm guessing most people don't care.
Something that worked for me pretty well. Basically I took some of teh ideas here and threw them all together in a script. These two lines are the marker for your regular hosts content. And here is the script I came up with. It does nothing else than just taking teh part between the 2 markers, copies that into another file and merges the updates into the new file and writes all back replacing the hosts file.
Hey buddy, you can remove redundant lines by running awk '! Well, I also don't recommend to cut "X" lines, cause it may vary from distro to distro… If you wanna make it run periodically, just add on boot or make a. Hey, nice post… But I'd like to improve your script, if you don't mind… Also, you should prevent detecing ad block with pinging the ads server, so it would be pretty to run a local server in 0.
If your machine is on-line, this can cause issues. Make certain the permissions stay the same. If you are really doing this on Linux you may be better off using something like dnsmasq or Marco Peereboom's AdSuck program or similar rather than putting into the hosts file.
It just sort of works on Windows but not on Linux. Mine really is a daemon and does a proper double fork and setsid and after the great fracturing of Linux into umpteen different distros I no longer automatically start the daemon but just put phttpd in this folder:. I start phttpd by first getting root running in a terminal. But first if you are going to put it in the hosts file you have to convert all of these 0. It does automatic I added the link to the wget line 2.
Looking for lines to start with 0. I added code to catch this. We might as well report which lines have problems, otherwise we have to go looking for them manually before we can fix them. Added code to print the offending info. I don't see the logic in using 4 lines cp, rm, mv, cat when the same can be accomplished in 2 cp, cat , so I cleaned that up.
Here's what I have. If anyone else can think of more improvements that can be made, please share them. Backup current hosts file, cd to tmp, download new hosts file printf "nBacking up current hosts file.
