I'm live in a place where internet bandwidth costs an arm and a leg. I have been playing around with Clear-Os, and would like to know how to block windows update and certain websites.

View 2 Replies View RelatedI have got a small queston: I have got several websites and some time ago I decided to delete some of them. As a result there is no virtual hosts on my web server, but if I will go to my_old_website dot ru I will be redirected to one of my current web sites (or if I will paste an ip address in browser), I want to know, how to block this?My virtual host's looks like this now:
Code:
<VirtualHost *:80>

I have installed Dansguardian on my little brothers laptop (using Tinyproxy and Firehol too) and I have it mostly configured the way I like it. The only problem now is that I can't seem to block secure (https://www...) websites, and he knows a few proxies that use secure domains. I was wondering if anyone has been able to make Dansguardian block these websites or is it just not doable?
View 1 Replies View RelatedI want to block a list websites from myself using a password that I don't know.I would randomly generate it or something.Everything revolves around sudo, though, so I don't know how.Long to short: how do I blacklist websites using a password other than my sudo password.
View 2 Replies View RelatedI'm trying to block specific websites, preferably using a portion of the url.
For example, if blocking [url], [url] would also be blocked. This implies that simply blocking a single IP using iptables would not work well.
The names to block will be somewhat dynamic, so a list specification would be ideal.
In my case, the LAN has a mix of linux and ms machines, and they all use a linux gateway currently running dnsmasq.
I find suggestions from using /etc/hosts (might work with yp, but not ideal) on the gateway machine, through to using squid on the gateway machine.
i have been looking up ways to block websites in linux but most all of the free ones only block the sites the software makers want to (or you can't block just the sites you enter without blocking the sites that it wants to)i need to know how to block only websites i enter with squid using webmin
View 3 Replies View RelatedMy internet connection used to be a direct LAN connection to my provider. Back then, everything would load fine on both Windows and Ubuntu (dual boot). However, a while ago they started needing me to dial using a username and password (over a PPPoE connection). But since then, I haven't been able to browse certain websites on Ubuntu, even though there have been no such issues on Windows. Some example websites are - Ovi's sign in page (although share.ovi.com loads fine, and nokia.com loads fine), Live Mail (works on Chrome(ium) and Opera but not on Firefox (both 3.6 and 4)) and other random websites.
Some of the websites that don't load show timeout messages on Chrome and for some websites, the browser will keep trying to load without an end (I've left it like that even for hours but not noticed anything different happen).
I have tried changing the DNS servers to the ones suggested in the comment. I have even tried booting from a Fedora LiveCD and then changing the DNS to those (and even to the ones of OpenDNS), but the exact same thing happens. Here's output of ipconfig on Windows: Opera error messages seem to be a little more informative and they have the following errors in turns:
Secure connection: fatal error (552)
Secure connection: fatal error (40)
Followed by: Opera was not able to connect to the server. The server may be using the unsupported SSL 2 protocol, which is not considered safe enough for secure communication. The site owner should upgrade to TLS 1.0 or newer. Does anyone know why this is happening and how it can be fixed?
Update: Just saw here [URL].. that someone else was having similar problem and solved it by putting a NetworkManager.conf file in /etc/NetworkManager. What needs to be in that file?
I tried troubleshooting this on the Ubuntu forums, but my thread went nowhere, so here I am! I'm REALLY hoping someone can help, because this is immensely frustrating.I just moved to a new house, with a new ISP. All of a sudden, all the machines running Ubuntu (there are 4 of them on my network) are having trouble rendering websites properly. Some websites are perfectly fine; some render with things missing (e.g., no photos or no CSS); some render as text-only; and some won't display at all - I get a "server not found" error.If I boot into Windows on any of these machines, there's no problem.To complicate matters more: Sometimes the "server not found" sites will decide to connect, then they'll fail again. This has been changing day to day (sometimes even hour to hour). Anything within the google.com domain is a good example of this.Two of the affected machines are desktops (one running headless as a server), and two are laptops. All four are running Ubuntu, but they're all running different kernels. The ONLY things these machines have in common is that they're running Ubuntu, and they're all connecting to the internet wirelessly.
Because things work properly in Windows without exception, and because (at least on the laptops) things work fine in Ubuntu on any other internet connection, I can rule out wireless network adapters. I have tried using two different wireless routers - no change. I have tried using 4 different web browsers - no change. I have tried plugging a laptop directly into the incoming connection, bypassing the router entirely - no change. I have tried purging and reinstalling Flash on one of the laptops - no change. I have tried to connect to affected websites using their IP addresses to rule out DNS issues - no change.This one has me completely stumped. The only thing I can think is that this is something to do with my ISP, but I can't imagine what it would be. I called the guy who runs the ISP (it's a local outfit run by one or two guys, as I'm living in the middle of nowhere), and he said there's nothing he's aware of at the ISP level that would be causing a problem like this.

View 3 Replies View RelatedI'm having a problem loading websites after a yesterday's "yum update" on F13. Before that everything worked fine but now when I open a browser, websites only load for about 2 seconds, after which any website I open just goes into a constant loading loop. I tried disabling the IPv6, as some threads suggested but it didn't help and pages still won't load. It happens on Opera and Firefox, so the problem seems not to be browser related. The connection is fine too, as I it works ok under Windows.

Today Software Update on Fedora 13 listed updates for OpenJDK, SSH protocol, and SE Linux policy configuration. When I clicked on the Install button I was presented with a list of nearly a hundred fonts that Software Update said were required. They were all fonts that I have removed from my computer over and over - fonts for languages that I do not speak and don't want on my computer.
I unchecked the fonts, but Software Update said it could not continue without installing them. Apparently they are dependencies of one or more of the three packages I mentioned above. Is there a way to figure out what package is constantly installing these fonts?
I note that after deleting the fonts I never have any problem with apps failing to run. And if I go to a web page created with a language that requires a particular type of font, Firefox still displays the page with the correct font for that language, even after removing the fonts from my computer. Are they really required?
I can't do any updates! it just gives a message like this: "The following packages block the update: kdebase-workspace-libs4+5"

View 1 Replies View RelatedI've written two web pages that show the status of a internal application. The idea was to display both of them, on two different monitors, using only a single PC with two graphic cards. The system will be mounted to a wall and has no keyboard or mouse. That's why I need a script that will automatically launch two instances of firefox (in kiosk mode), each on it's own monitor.Currently the OS installed on the PC is OpenSuse, but I'm free to install a different linux flavor.So, how do I launch firefox on a specific monitor?
