Bold/italics is to emphasize not to express hostility.

"This question" refers to "how to block websites in linux os" by the OP.

I believe that jlinkels's apparent hostility was not directed to you, and that he wasn't actually referring to your comment (which fully makes sense), but to the OP's vague formulation of his/her question. In fact the LQ netiquette does recommend that questions respect a few criteria, which the OP apparently didn't consider, but of which he has now been made aware.

I typed that into DuckDuckGo
First result was http://www.addictivetips.com/ubuntu-...-ubuntu-linux/

So search engines can answer rhetorical questions!!!

He did, instead. The thread title (previously simply "Urgent") has been changed as mentioned.

I don't understand where you see this kind of attitude from me. I just reported to change the thread title in order to be more descriptive and to give the thread more exposure. That's all.

There are a few ways to block websites in linux. The hosts file is one way. Two links have been given for that method. Another way is to set up IP tables, as has been mentioned. I tried both of those methods and could never get them to work for me the way I needed--probably because I didn't need specific sites blocked, but whole categories of sites. The method I used was to use a proxy+blocker, like squid+dansguardian, or squid+squidguard. This worked for me because it was easier (for me) to set up than trying to figure out IP tables or blocking each site in the hosts file. Also, I could block whole categories (advertisements, malware, etc.) with just a few lines typed into the dansguardian configuration file. Also, those categories were updated through automatic downloads of blacklists every night.

Anyway, method 1:
Edit the /etc/hosts file (google search: How to block sites using /etc/hosts)

Method 2:
Set up IP tables (google search: How to set up IP tables to block sites)

Method 3:
Set up a proxy and blocker (google search: How to set up proxy on linux; how to set up dansguardian on linux; how to set up squidguard on linux)

Good luck!

Apologies, but would of helped if you'd left the offending headline as is rather than changing it, then the warning would have meant something.

Oooh...))
You can block "google.com" so, add to file "/etc/hosts" this line "127.0.0.1 google.com".

Too, you will be able to block site so, install "safescript" plugin to google chrome and edit him preferences.

Of course, most site blocking methods are easily circumvented by a 5 year old...

How?

Usual workround is by going via a proxy.

or OpenVPN =)

Or if it is a local (on the same computer) block, simply stopping the process often works, too.

We lost the OP.
