Anyway, my internet has been working fine until recently (last week or so). For most sites, Firefox will load the page quickly. However, every once in a while, but frequently enough to annoying, it will say "loading" for 10 seconds, then direct me to OpenDNS, which says the page cannot load. When I try it again, I get the same problem. Other sites are fine.
Then, when I quit Firefox and restart it, that site will work fine, but soon enough, another site stops loading properly.
For example, Google will work fine for awhile, then I'll get the error, but after restarting, Google will be fine again, but now Wikipedia, which loaded before, gets the error. And the cycle continues on yet another website...
I haven't changed any Internet or network settings recently. I'm on Ubuntu 10.04.
I have an odd thing going on with DNS. I have two machine's running Ubuntu and for some reason they do not always resolved internet addresses on my Internet connection. This has gone on since the Ubuntu 8.04 when I first started using Ubuntu. Anyway, I use OpenDNS' DNS servers and I have been running perfectly.
This is what is odd. My Windows XP Machine never has the problem. It always resolves. Does Windows Possibly have some Microsoft hosted DNS server hard coded in there as a backup? Things are working fine this way so I am not looking to change. I am just a little puzzled and finally got around to asking, "Why is this".
I would like to kindly ask you for some advice. Allmost a month I am experiencing strange behaviour of the system. I use Debian Wheezy 64bit on Intel Core i3 processor, SSD hadr drive, 4GB ram. Problem is, that sometimes the system becomes very slow when booting kernel, the kernel booting stops for 5-8 seconds on something (timimng, Processor initialization or something related, but not always the same thing) and then the system is booting noticeable slower than usual and when in the graphic environment (I use gnome) everything seems to be slower than usual, the typing in console is slow with lags and videos (movies) are not watchable due to freezes and lags.
I was trying to figure out what is causing it, the only thing I came up with is, that when I wait 10-15 sec in grub menu before selecting the kernel and after some time I manualy hit enter, it usualy boots fast and with no additional issues in the system. Sometimes it boots up normally even without this longer waiting time, but sometimes not. It is strange.
It seems every 30 seconds the internet lags, after that it is fine for 30 seconds. And this happens continuously. Also it seems when I am on Firefox if I am connected to a website, I can navigate the website with not further trouble. But if I navigate away and try to go back, it takes a while. I didn't update, or upgrade or anything. I am running 13.1 and have been since it came out. This just started with the internet 2 days ago. Also I have a dual boot with Win7 and the internet is fine on Win7.
So I'm going to try out opendns as an internet filter. But I'm not doing it on a network/router, just on my local machine. Using ubuntu, I read that I need to select each connection and change the dns settings.Is there a way to generically add the dns settings so that if I connect to a new network I don't have to manually update it's settings?
I am trying to block unappropriated sites on my ubuntu 11.04 with openDNS I installed it and in addithion to the catagoriegs I checked I also added some sites to the always block list, everything according to the site should work. But the problem is that nothing is blocked (also the sites in the always block list). I cleared the browsers cache but it didn't help when i try to clear the local cache with the provided command in their site I think it says it ignored my network.
About firefox,I want to block images only on facebook automatically so I added [URL] to the always block list in the images category and it should work but it just won't block the images. I should note that I use the same method on chrome and there it work like a charm. how to get that working on firefox?
So for ive changed the dns on my home router to Opendns and ive added this What does a dns attack look like? how would i know is my dns was poisoned or if i was under a kaminsky style attack?
I've started using OpenDNS on my network, the problem is, my router gets an dynamic IP, which means I have to regularly update the OpenDNS settings.
DDClient apparently supports OpenDNS, but the Ubuntu package for it asks for various details I don't know, and can't find. I'd rather not have to boot up a Windows computer just for this.
So I've got two questions, I guess - first is, are any of the Windows clients known to work under Wine (that can retrieve the IP from the router and forward it), and the second being, how exactly do you set up DDClient to use OpenDNS?
I am having trouble setting up FamilyShield on an Ubuntu 8.04 system. The setup instructions on this (opendns.com) site are for newer versions of Ubuntu. Network Manager settings are different in 8.04 and don't correspond to the instructions. However, given the age of this computer, it cannot run a newer version of Ubuntu, and 8.04 is an LTS supported until 2011,
Complicating matters is I am living as a guest, so do not have the option of setting FamilyShield on the router. It must be done on my computer.
Here's what I've tried: System->Administration->Network
go to DNS Tab and add the FamilyShield DNS numbers. BTW, there are two DNS numbers from the internet owner's ISP (Roadrunner) automatically in here already, along with "socal.rr.com" in the Search Domains field. If I try to delete them, they reappear when I reboot. If I add FamilyShield DNS numbers here, either along with, or in place of the ones that automatically appear here, they do not take, and on next boot FamilyShield DNS numbers are gone, but "socal.rr.com" DNS and search domains reappear.
I've also tried:
Code: sudo gedit /etc/dhcp3/dhclient.com and added following line at the end:
Code: prepend domain-name-servers 208.67.222.123,208.67.220.123 When I reboot the system, I'm still using the assigned DNS numbers from "socal.rr.com".
I was able to try a newer version of Ubuntu (on a different machine) on this network, and it worked fine with the setup instructions. So this appears to be a problem specific to how Ubuntu version 8.04 handles DNS number changes.
When I watching video with full screen mode of VLC, the video is so lag that it makes me angry. The video display normal by Totem, Gnome Media Player, Mplayer (but these application has too much bugs) . I use Ubuntu Lucid. VGA Intel 945, P4 3.0, Ram 1GB DDR2.
I recently installed Ubuntu 11.04 on my Gateway MD2419u the specs are:AMD Athlon X2 QL-62 / 2.0 GHz processor,ATI Radeon HD 3200 graphics,DDR2 ram this should be sufficient, should it not? I have updated software and installed the additional proprietary drivers.
I have Ubuntu 10.04 installed on my Dell Dimension 9100 it has a dual core 3ghz possessor. 2.5 gigs of dual channel ddr2 memory, with a nvidea gforce 9400 1gig of memory graphic card. I installed the game a couple of weeks ago, everything works really good, but in the last couple of days when I am playing the game it starts to lag really bad during game play, it goes in and out of the lag, if I wait 10-20 seconds it will get back to normal, but it is very annoying.
Sometimes (not always, mind you), several applications, lag. A lot. For instance, Blender 3D is entirely unusable and don't get me started on Fallout 3. Other examples include Minecraft (Not the Windows .exe but the .jar) and XMoto. So I assume it has something to do with the graphics driver or the likes. For some reason, Compiz still works fine. The only way I can fix those lags is to reset X, which is not exactly a good way, especially because this happens to shut down uShare and thus cancels my movie stream. So..
For support reasons, here's my setup:
CPU: Intel Core 2 Duo E4500 (2*2,2GHz) Graphics: Nvidia Geforge 8600GT, 512 MB 2 GB RAM 500 GB HDD (The Maverick partition is 159 GB, 2 GB Swap) Some hama WiFi-Stick ForteMedia something something audio card
Today I noticed a large sound gap while playing Minecraft. There is about a second of lag between an action and the sound effect. This wasn't happening the night before, and I thought it might be a problem with Java or Minecraft until I noticed it on a flash application in Firefox. I've tried killing pulse audio, but I noticed nothing. I also looked into the sound preferences and tried the speaker test, which had no lag.
Other possibly relevant information : I dual boot my laptop with Windows 7 and Ubuntu 10. Ubuntu has some updates ready, but I don't believe its relevant because the problem just started.
I have a problem multitasking in ubuntu. all i want to do is be able to browse the web or play a game while listening to music, currently trying to do this slows or makes music lag.I have a dual core processor and 2 gb of ram, and ubuntu runs lightening fast, even while multitasking everything but the music runs great. i can do this in windows, so i dont see why i cant do it in ubuntu.
i have watched my cpu and ram monitors while doing this and there are plenty of unused resources, i believe neither processor core ever tops 20% while trying to do this, and ram, 7%. I want ubuntu to use the extra resources instead of taking away from my music playback. And what i mean by games are like quadrapassel and simple stuff, im not trying anything difficult. So my question is; Can i make ubuntu use more resources, or never sacrifice music quality?
Since I upgraded to Maverick, every now and then (maybe once an hour) my system becomes very slow for about half a minute. The mouse cursor reacts only very slowly and also applications freeze for for some time.
This happens without the CPU being on full load or the hard disk being active.
I made a clean ubuntu installation on a new hard drive a week ago, but the problem persists.
I have a Thinkpad R400 with an Intel GMA 4500 graphics card an an Intel T5670 Core 2 Duo processor. I'm running the most up to date stable version of ubuntu. Kernel 2.6.35-22.
I know the description of the problem is very vague, but it's hard to describe it more accurately. I couldn't find anything helpful on google or the forum. If you have any ideas what might cause the problem or which log files might provide useful information, please let me know. Most importantly, the problem did not occur before I upgraded to Maverick.
I use an online screencasting java applet called screencast-o-matic to record my screen. While recording, I use Compiz's annotation tool. Normally this tool works great, but for some reason while I'm recording, it gets very laggy (drawing is way behind the mouse movements) and less smooth. For example, drawing a circle at a quicker pace not only causes lag, but also makes the circle look more like a polygon with straight lines. While this is happening, my CPU also spikes, with large strains showing up on the java process. I'm running Ubuntu 11.04 with an intel i7 processor. Any ideas as to why annotation lags badly while screencasting, and any ways to fix it,
After I upgraded from kernel 2.6.32-31 to 2.6.32-32 and then 2.6.32-33, my sound started to lag(the lag occurred on 2.6.32-32 and stayed to 2.6.32-33, but it worked perfectly ever before). Sound does work in itself, but frequently lags and pieces that were already played before will be played again, pretty much like an old vinyl that occasionally jumps or hangs. When I start to replay something, it does not put out anything for a second or two and then starts, when I stop it will keep playing for the exact same amount of time. So, sound is synced to videos(video replay works perfectly well and without the lag). Problem is definitely related to the sound drivers, not to replay software or any buggy file. It occurs with DVDs, Flash Videos in Firefox, music in gmusicbrowser, movie files with VLC, whatever you want. I never experienced such problems with any kernel before. Although I've seen many others posting similar problems, I cannot see any valid solution for myself.
I'm running Ubuntu 10.04 and I sure don't want to go to 10.10 for the second.
I reinstalled Alsa and Pulse, no joy. My sound card is recognized correctly by alsa and can be found in aplay -l. It's a generic onboard surround sound device, although I only use stereo channels.
Why system lags so much while working with a lot of files or with big files (copying them, erasing)? How it can be solved? I am running Fedora 12 x86_64 with ext4 filesystem
The program mplayer lags when playing high quality media over the network. This is not an issue when playing locally, but it becomes an issue when playing large (>= 1 GiB) Matroska video files over the network. By "lag" I mean that the animation freezes at a fixed frequency, every five second or so the animation will halt for a fraction of a second, which is very annoying.
The network is a 100 Mbit switched ethernet network, I typically get around 10 MiB per second in actual flow rate and there is no noteworthy traffic on the network that degrades the performance. The lag is there regardless of traffic.
If I have a file at 1.4 GiB which is 60 minutes long, shouldn't that equal < 0.4 MiB/sec in required flow rate? I.e. I should be able to play this file over a 10 Mbit network. Yet, even on a 100 Mbit network this doesn't work.
The computer I use to play this media is a 4.12 GHz Core i7 with 6 GiB RAM and a GTX480 graphics card. I have the latest graphics drivers. I use Slackware 13.1.0. I use a custom, small and highly optimized kernel (although the same issue is there with the standard kernel). My version of mplayer is MPlayer SVN-r31498-snapshot-4.4.4.
The network protocol used is SMB, i.e. I play from a mounted SMB resource.
I have tried to host the file on different computers, both are dedicated file servers, one is a Pentium 4 3.0 GHz with 2 GiB RAM with no load other than hosting files, the other being almost equivalent except with a 2.8 GHz CPU. Watching the system load on the machines yield nothing of interest, sending a mere ~0.5 MiB per second is nothing for a computer like that, even though a P4 is not exactly new anymore.
What is interesting though is that if I use the "-vo gl" argument to mplayer, the performance is greatly improved, there is very rarely any lag.
Now correct me if I'm wrong, but why on earth would the video output driver chosen affect the performance on a machine that has a 4.12 GHz Core i7 CPU, plenty of RAM, a very fast graphics card, and nothing else to do? I.e. no load at all? When I use the standard output driver, there is almost no load at all on the system. So what the heck is this?

Alright, on my last Linux installation I know I did not get graphics lag this bad.
So I go to move a window around, Nautilus, Firefox, a Terminal, and when I move it it takes a second to reach the location and refresh on my screen, and if I move my mouse within that time period then it will move the window somewhere I did not want it.
I disabled Smooth Scrolling in Preferences => Advanced => General for Firefox but I do not think it helped. It takes ages to scroll to where I want it and by the time it gets there it keeps going because I scrolled too many times. I receive scrolling lag on seemly any document of text, this includes gedit as well.
I'm working on finding out what graphics card I have so I can see if it has Linux drivers. I know it is an ATI, but I have no idea how to get its name using Linux commands.
ever since i started using opensuse at the end of december, this has been bugging me. when i try to watch a full-screen videos video in either chromium or firefox, it lags to the point where maybe i'm getting 0.5 frames per second. ironically, when i launch chrome in virtualized windows 7 (virtualbox) to watch a full-screen flash video it looks smooth as butter. yes, even with the virtualization overhead and everything.
i'm using adobe flash 10,3,181,22 from the opensuse repositories, chromium 15 and firefox 5. i'm on a 64-bit system.

For example, drawing a circle at a quicker pace not only causes lag, but also makes the circle look more like a polygon with straight lines. While this is happening, my CPU also spikes, with large strains showing up on the java process. The lag makes it difficult for viewers of my videos.
I am trying to connect my desktop to my laptop over a non-internet connected LAN, but when i enable the LAN connection on my desktop (the one with the wireless) its internet stops working.
it is a very similar problem to this except that i am using ubuntu for the machine with the two connections.
right now i have my wireless on the 192.168.1.* address space, while the LAN is to be on 192.168.5.*
note: my goal is not to share internet with my laptop, just be able to connect to it and the internet at the same time.
desktop: ubuntu 9.10 , wireless and LAN laptop: windows xp, LAN only
I'm trying to set up a wireless AP with Internet sharing. I currently have the AP setup with hostapd and a dhcp server. The clients can connect but there is not Internet sharing. Now my situation is somewhat uniqe in that my internet connection is my teathered android cell phone. The tether app is azilink and i use openvpn to create a virtual networking interface(tun0).
On this box I have Two seperate Ubuntu installations. Recently in both I seem to be having the same problem. I initially can connect to the internet as per normal and use any internet application. But after a period of time, sometimes just minutes, sometimes hours, even though the icon says connected, I cant update pages or send emails etc because there is no actual connection. My Physical connection is good I know - My Ubuntu laptop and Windows gamming PC connect fine during this period. So
Does this suggest an intermittent hardware fault or is there some thing in Ubuntu I can check to make sure that it is setup correctly and nothing has been corrupted? I am a lay PC person - I dont really want to be command prompting - Plug & Play and Point & Click is my limit.
