General :: Networking - Can't Access Select Websites (but Can On Windows)?
Nov 21, 2010
My 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 just installed Fedora 15 and everything is working ok except i can't connect to some websites such as facebook or hotmail. I tried doing the same on windows and everything is ok there. I've been searching through forum about this problem but nothing seems to help. Has anyone else had this kind of problem and managed to fix it?

I have been studying LAMP for a while now and all my websites are on the localhost. But if i wanted to access my websites from a different computer, how do i access do that? LAMP (192.168.0.2) client (192.168.0.3). Do i need to setup the DNS servers as well in my home network for me to access my intranet (LAMP).

recently I have bought a new wireless router and now I have problems connecting to some (secure) websites. I can't login to gmail and facebook while I am still able to connect to these sites using my old router. I have also tryed to connect to these sites using my new router on windows and it worked with no problem.It is really strange for me, although I don't know that much about networking. I am using Fedora 13 and a TP-Link (TD-W8901G) Wireless router and I have these problems using both wired, and wireless connections with this router.

I am in the process of setting up my own Linux gateway/firewall using two nics eth0(external network) and eth1(internal network). The Linux gateway hands out ip addresses using dhcp3-server, and uses iptables to route the traffic correctly. Clients are able to connect and access the internet...everything is working great, HOWEVER I can't access my apache virtual hosts websites from the internal network? They work just fine if i access them from the outside world
I can type ip of the web server, 192.168.0.201 and it shows the first virtual host listed in my /sites-enables/000-default folder. but i can't use any DNS entries. I don't have any internal DNS servers running. This doesn't makes sense, because if i replace the linux firewall/router with my normal linksys wrt54G router it works just fine.

First off, since this seems like a networking issue I put it here, but if it should be somewhere else, the powers that be should definitely move it over.
I'm using Ubuntu 10.10 on Dell Presario M2000 I have made sure that all updates have been done.
As the subject states, the admin account (mine which I'm posting to the forum with right now) can access the internet and see webpages. The user account on this laptop (my underaged sister who my parents don't want full access to the computer) will not access any webpages, it just continually looks like its loading.
I have made sure the wireless card drivers are installed and activated.
Also, I ran iwconfig and ifconfig and here are their results
p { margin-bottom: 0.08in; } Results of iwconfig
lo no wireless extensions.
eth0 no wireless extensions.
wlan0 IEEE 802.11bg ESSID:"myqwest4137"
[Code]....
These were both run from the user account. At this point it looks like its connecting to the internet through the wireless card as I was also able to run the update manager through the user account and have it download the updates (after putting in my admin password of course).

i was tasked to setup a proxy server to block access to some websites. i'm using centOS 5 and Squid 7:2.6 STABLE21-6.e15...i appended the following and tested the configuration with the supposed server i am using and the it does seem to work but now i'm wondering how i can test it with a client computer..i have 2 LAN cards and i just connected the other to one PC (can a direct connection work or does it need to pass thru a switch or hub)...i just can't figure out how it should be... how do i configure the 2nd LAN card to use this computer as its proxy server?

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.

I have a dual boot system (Linux and Windows) that I normally run headless and which boots by default into Linux (which is what I use mainly). This all works fine, except that on occasions when I want to boot Windows I have to plug in a keyboard and monitor just to select Windows in the initial grub boot screen. I'm wondering if there is an easier way to do this ? I don't mind if I have to boot Linux first, I just want to be able to reboot into Windows occasionally without having to plug in any peripherals.

I had Fedora 12 installed on my laptop and everything was working okay.
After making a fresh install of Fedora 14 I can now only access some websites, others cannot be found.
I have spent hours trying to resolve this without success.

I'm using Ubuntu x64 (dunno which version, but I don't think it matters) and I'm concerned about security with PHP.I remember using lighttpd and I had some mystic configuration and the secuirty was perfect for me - if one website gets hacked then the others are still safe (kinda).Now with apache2 if I enable safemode I'm still able to go outside web directory and actually I can go really far untill user/group matches.I tested the system with r57shell and I was able to mess up other websites.Is there a way to disallow access to other websites?

I have managed to configure AWstats to work from one server to access the log files for multiple websites on multiple servers and even managed to write a little front end php site to access all the different conf files. I want to know if there is a way of combing two conf files for the same site but are on two different servers in a loadbalanced situation. so my conf files look something like: [URL].. I have to monitor bandwidth for our websites and its gets tedious switching between the various conf files for the same site and totaling it up so I was hoping I could combine the output of both conf files on screen using some funky command in the awstats.pl script

I just installed Opensuse 11.2 dual-booting with Windows 7 on a laptop. I have the wireless set up and connected, but I can't seem to be able to connect to any websites or ping Google, etc.I'm kind of a Linux newbie, so I'd like to get some advise as to what I can check to get it working? (Windows 7 on the same machine is able to connect - I'm using it now)
- I've tried both automatic DHCP configuration and also setting the ip/dns server manually, no luck

I'd like to be able to limit access to a particular website, based on the time of day. I would also like to be able to password protect this if possible.So for instance, from 7am until 10pm daily, I can access URL... but after 10pm it redirects to 127.0.0.1 or something. And this configuration be protected by only allowing a certain user (other than root) to change the config?

I have been trying to get Squid to work so that I can restrict access to a particular web site during certain hours every night. I can't seem to get it working, however. I am still able to access the site. The following are the relevant lines from my squid.conf file:
acl restricted-domain dstdomain "/etc/squid/denied_domains.acl"
acl test time 19:00-20:00
acl bedtime time 22:00-23:59

I am facing a problem concerning secure websites where I get the "Connection Reset" error in browser after a timeout of I think 1 minute.
OS: Fedora 14 ( I faced same problem with Ubuntu 10.10 )Browsers: Chrome and Firefox
The issue is not there on Windows using Chrome and Firefox so I believe this is a problem with how linux manages secure connections. I can access all the google secure websites too. There a few other websites apart from facebook.com that I know which I am unable to access.

I want to configure a remote internet facing server as git server. I would like to restrict access to the server to a few systems (access is restricted to select computers, not users). I first thought of using ssh key, but the key can be copied to another system hence that alone is not sufficient. I am having a dynamic IP, so simple IP based firewall blocking is also not possible. I was thinking about the possibility of using both SSH Key and IP based access. Is it possible to update the firewall rule whenever my ip gets changed?

Ive managed to install samba, I've shared a folder. I can access from a Windows 7 machine via \ubuntupublic. I can put files in the folder form the ubuntu machine and edit them on the windows box. I can put files in the folder/share from the Windows box but then I cannot edit them on the Ubuntu machine (they are read only and have a "Lock" over them). I can fix this by going to the properties of the file/folder in Windows and manually assigning "Everybody" full control (then the lock disappears and all is well.) I want read/write access to all the folders contents from both machines all the time (security is NOT a concern I WANT the permissions wide open) what am I doing wrong?

I have recently zypper dupped to opensuse 11.4 from 11.3. My only problem is I am unable to access my address book when I click <select> when sending a new message; only recent addresses show in the window that pops up. Even if I select <all> in the list of choices, only <recent addresses> show up. In the useful tips that appear upon opening K-mail it states that if I click on < folders> then < Mailing list management> I will be able to select and manage all of my address books. But when I click on <folders> the <mailing list management> is faded telling me that it is not enabled. My question is what must I do to enable the mailing list management to be enabled? I have enabled mailman with no help.

I was having no problems (that I knew of) browsing the web since installing Ubuntu 10.10 a week or so ago. I was previously trialling Win7 as my customers will likely be using that in the future. Then I wanted to go to internode.on.net. Got the following: Quote: Firefox can't establish a connection to the server at internode.on.net. or Quote: Oops! Google Chrome could not connect to internode.on.net
As it was just after Christmas I thought it must be down, for upgrades or maintenance etc. I later tried to go to Freebsd.org; same error. I've been having a small number of other websites give the same error. I thought nothing of this until I tried it on my wife's macpro. I could log onto all the websites I wanted to and none gave any indication of having been down. Both boxes are on the same adsl connection. I still can't access internode or freebsd on 10.10 yet have been able to access every website on OSX. Now, I was only looking at them for info but am worried I won't be able to access something important. (so far everything I 'need' is working)
ping just drops out. edit: weirdest thing! I just retried and now can not emulate the problem for internode. freebsd still won't show. that is less than five minutes between problems and resolution! I hadn't even posted! But I still would like to have an idea of what is going on. Here is the ping error for freebsd: Quote:
