Ubuntu Security :: Some Sites Blocked - Accessing Some Sites - Amazon Paypal And Bigstockphoto Really Slow
Feb 9, 2011
In the past week or so I've noticed some weird network behaviour. I find accessing some sites such as Amazon, Paypal, and Bigstockphoto really slow. Sometimes the page will not load at all. Other sites are fine. The problem sites are not a problem for others on my LAN at home. When I try to open the problem sites, I can see in Firestarter blocked connections coming from 2.1(8/9).xxx.xxx on various ports such as 36007. This only happens for the problem sites. I attached a typical output from firestarter.
This happens with Firfeox or Chrome. Using Ubuntu 10.10
I have just installed ubuntu 10.1 along side my windows xp. It installed nicely and boots up promptly. When I try to go to a web site, it takes forever to load. It can take up to 1 minute to load a page. Why is that. I thought that Linux was supposed to be faster. When I go back to windows, I don't have this problem.
Over the last 3 or 4 days, I have been unable to load sites that serve their images, scripts and whathaveyou from Amazon's cloudfront domain.
[URL]
I have made no changes to any of my networking files, hosts{allow,deny}, or dns settings.
Connections don't provide any errors, just continually fail to load. Stopping the page load after a while reveals the raw HTML in some cases (quora and blekko).
Tested in Firefox, Chromium, Midori and Vimprobable.
I have booted into another distro and pages resolve immediately.
I have disabled IPV6 and my firewall - to no effect.
I am in China, where some web sites(....., facebook, etc) are blocked. So I have to access these blocked site by VPN. But how can I access blocked sites by VPN and unblocked sites by my direct ADSL?
i have seven department in my office. i want to restricte web sites for all the departments but not same web sites for all the departments i.e. different sites for different departments.i have no idea about this issue.
For a while now I've got a problem when surfing the internet. Everythings fine for let's say 15 minutes and then all of a sudden it takes about 1 minute to load a -random- page, once it has loaded, everthing's fine again. Transmission does not seem to have this problem. I'll double check this. Looking thru the forum I found the following "solutions". None of which has worked for me up to now:
- disable ipv6 in firefox - set method under network manager to "Automatic (DHCP) addresses only" and use google or OpenDNS dns servers - change resolv.conf (comparable to the second one I guess)
Yesterday I've installed Ubuntu 10.10 . Everything is fresh new but my I can feel some lack of speed in the desktop and sometimes if you look really hard on the monitor you can see that screen is trembling a little bit. Not long before, the system freeze up and I had to manually force reboot.
I think that the root of the evil might be the integrated graphics from Intel Core i5 2500K processor. What's your opinion ?
When i starts it for the first time,my sites getting loaded fast when requested through browser,but slows down gradually. what could be the reason, my cpu load seems ok. Because i have another site hosted through apache in the same server and its getting loaded fast. so what could be the issue.
I dual boot XP and FC14 and have 2 routers. I can connect and ping one of these routers when I'm in FC and I have an IP address I just can't load any websites. When I connect to the other router (my main router) it works fine. When I boot into XP and connect to the problem router I can load pages fine. It's only when I'm on FC14 and connect to the problem router that I can't load pages even though I have an IP and can ping around.
I've recently installed openSUSE 11.4 (64 bit) on my system and am experiencing severe performance issues with websites using https (any site using https). Page loads over https take anywhere between 30 seconds to 2 minutes. It's the same issue posted here Secure sites load slow or not at all -- there was no confirmed solution.
- My router/hardware configuration has not changed in a long time and I've run Ubuntu, Arch Linux, and Windows XP on the same machine within the last year and have not had any issues. - I also have a laptop running Arch Linux (kernel 2.6.38) and this problem does not occur using Firefox 4 or Chrome. To add to the madness this problem occurs while running Firefox 4 inside a Windows 7 guest via virtual box, but NOT while running IE 8 inside the same guest. - This issue occurs using Firefox 4, Chromium, Opera, Konqueror, and Arora. - I've disabled ipv6 in Firefox via about:config. - I've disabled ipv6 in yast and have attempted to use both the "ifup" and "networkmanager" options. - I am not using a proxy server. - I've attempted the fix posted in the Ubuntu forums for a similar problem [ubuntu] [SOLVED] Banking Site is very slow.
How do you know if a site is safe to download from ? Have only been using Mint 11 for 3 days after 7 years with windows and the usual safety nets there were the https headings and firewalls blocking stuff but how do you know something is safe in Linux ? In short how do you know it's a trusted site ?
I want to check if traffic to a specific URL is being throttled by a hospital acting as an ISP. A client is having great trouble accessing a hosted web-app from inside the hospital, but access is fine from outside. The hospital IT dept are not interested as the rest of the Internet is fine. I need to trace where the latency is creeping in or where the throttling is happening, if I can do that, the hospital will remove it. Traffic is standard http to a specific URL.
I have a problem with sites or domain blocking by squid proxy server in rehl 5. I have trying lots of time but i'm not succed.pls help me how to block sites or domain in rhel 5.
My sites on the server are loading very slow, though my server load is under 1.00.What can be the problem, when ever i restart httpd the sites starts to load instantly.
I am running Ubuntu 9.04 32bit on a dual boot (XP) computer. No internet problems in windows, and I am currently typing this post on my wifes HP laptop running 9.10. I have no browsing ability on the desktop running 9.04, and updates don't work (in details, every other line fails) But, I can bring up Google, and search it, pictures and all, but cannot go to different sites (ebay, hotmail, amazon as the first few i try). Also, my pidgin works fine, as I am talking on it now. I have tried to turn off ipv6 in Firefox and ubuntu, neither doing anything noticeable.
After upgrading to 10.04, Firefox sits showing "looking up" as it takes as much as 1 to 5 minutes to find a site and all the different things to load the site. A few sites just pop up as they should, but many take a long time to ever come up...and it is not the site. Sometimes the same site will load quickly and the next time will take for ever to find.
I have a very fast connection, everything worked fast in the old version and in windows. I have went through all the about:config things to speed up Firefox.
Im having trouble using my wireless usb dongle. I've installed the software and connected to the web, but i can only access a number of websites.
I can access ....., and watch vids and perform searches on google, bing, yahoo and the like. However when i try and access a site that i have searched for it takes me to the internet providers homescreen and tells me to activate my account or top up my account.
I know i have enough GB left as i recently activated my account and i'm able to use the wireless stick on another computer without any problems on all websites. So this leads me to believe that there is maybe a problem with my browser or security settings, but im not sure what to do.
Pages do not load on certain sites (such as LinkedIn and Which? for example). The sites themselves load but when I click on links the pages load forever. With Which? I can close FF and open it again and then the link loads but after a few clicks they stop loading. It happens on all browsers (at least I tried FF and Chromium) but OK on Windows.
