Networking :: Script For Faster Internet Experience
Feb 27, 2011
I came to know about namebench tool while working on a setup of DNS server, test results showed some servers working pretty fast. After investigating different options and many tests i managed to keep a good rank of DNS slave server. The idea was to keep checking available fastest DNS servers in the region and modify named.conf accordingly.As many of us are not building a DNS server, I am not going to discuss it in details here, however in case you are using some flavour of GNU/Linux, UNIX you can use following method to have a faster internet experience.
To have it accomplished we are going to use namebench, cron and a small script. namebench looks for the fastest DNS (Domain Name System) servers accessible to your computer.

I am using Red Hat Linux enterpriser 4 using two physical LAN cards.There are two different ISP internet lines coming into a single gateway computer. Is it possible that if in our one network we are using 2 MB bandwidth and from another network we are getting 2 MB bandwidth.(Two different Networks) and combine it into 4 MB. In bonding it combine the bandwidth or it do loadbalancing ?
The question is can we accumulate or add these two bandwidth in Linux machine and it sent total bandwidth 4 to the end users ?
Lan Card A
IP Address: 192.168.1.250 2MB Bandwidth

So I switch between Ubuntu and Windows alot, because some games I can only get to run smoothly in the windows environment. Anyways, one thing I have been noticing ever since I got Ubuntu but never really questioned, was about my download speeds. When downloading a torrent in Windows, I topped out out about 2.0 mb/s. Where as in my Ubuntu install, running the same torrent program (utorrent) and downloading the same file, I was getting 3.0 mb/s. I was wondering, what is it about Ubuntu that is utilizing my internet connection better? Only a hand ful of times have I ever reached 3.0 in my windows install (such as right now while I am downloading a game through steam).

I'm having trouble with 802.11n as of late in Ubuntu. I know my wife's computer used to connect faster but it seems to not be able to go over 54 Mbit in 10.10 any more either. Laptop is a stock Sony Vaio VPCZ12CGX/x which has an Intel Advanced-N 6200 card.
LSPCI output: 02:00.0 Network controller: Intel Corporation Centrino Advanced-N 6200 (rev 35)
I can connect to the 2.4Ghz channel or the 5Ghz channel on my wap both are capable of up to 300Mps as per its configuration but neither go over 54Mbit. Both do about 160Mbit from this same location in Windows. Moving closer makes no difference.

I have an openvpn bridge up and running (ubuntu to ubuntu, both in vmware fusion machines on macs). My problem is that I cannot get a connection faster than ~9mbps even though 20+mbps is available. I've been troubleshooting for a while and have tried many fixes. I just now did ethtool tap0 and I think maybe I found it. It says the link is 10mbps. I tried to change it with:
sudo ethtool -s tap0 speed 100
but it says ethtool cant change speed on tap0. How can i define the link speed of tap0?

I'm setting up my first Linux laptop with Ubuntu 11.04 and my CB21ag wireless card works, but won't achieve speeds over 11Mbps (maybe not "doing 802.11g rates for some reason?) I guess this cardbus card is manufactured by Atheros for Cisco so I maybe that's why I'm seeing two wireless connections - the one with the "airo" driver gives me 11mbps, the other with the ATH driver would only get me 1mbps so I deleted that. The card seems to disconnect/reconnect periodically too - messages pop up frmo the wireless icon ...
lsmod says "airo" and "ath5k" are loaded
So to get 54Mbps (802.11g speed) I'm wondering if theres maybe a different driver module for the CB21ag card or some configuration I need to tweak. More info - security is static WEP, lshw -C network returns some "wierdness" about network 0 ?
-laptop:~$ lshw -C network

I am stuck with Fedora 13 due to the fact that clutter has some nasty bug which colides with the nvidia binary blob driver (I _require_ CUDA _and_ usable 2D/3D). So the new version is out since some days ago but not yet in rpmfusion. So did anyone give 260.19.29 a shot and does the 2D/3D UI still lag?

For some reason, my downloads on Windows are really slow no matter what download accelerator I use. I've tried IDM, FDM , DAP , DAM , Orbit , Supersonic , jDownloader - they all have some problem . Sometimes the files just halt and refuse to be downloaded.
Warning : Not For Advanced Users!
On Ubuntu though I have found a wonderful solution that sees me all the time maxing out my download connection and often exceeding it with absolutely no problems.
Here's the combination :
Aria 2 + Flashgot.
I will show you how to set it up, how to configure it and how to pause , resume downloads.
That's all one needs!
1. To get started , let's download Aria 2.
Fire up a terminal and enter
Code:
sudo apt-get install aria2
2. And now Flashgot : Install the add-on from this site: [URL]
Close Firefox
3. Now to choose Aria 2 as the default download manager
Open Firefox
Tools
Flashgot -> More Options -> General Tab and select Aria 2.
4. Now in terminal:
Code:
cd
mkdir .aria2
Now create a file called aria2.conf inside .aria2( which is a hidden folder can be viewed by pressing Ctrl+H in the Home Folder)
Code:
cd .aria2
gedit aria2.conf
5. Open the file and type split=100 on the first line. That does it . Now to download anything say for example a video from ..... : [URL] in the bottom right corner click the flashing icon ( Flashgot Media) or alternatively go to Tools->Flashgot->Flashgot Media
6. Your download will start after selecting a download folder. A window will open which will display progress. To Pause , press Ctrl+C.
7. To resume open History, navigate to the page and again click 'Flashgot Media'
The file will resume.

No matter what desktop I use, there are 5 nepomuk processes and one virtuoso-t process running, taking up quite a lot of CPU in total. These stupid things have been ruining my Ubuntu and KDE experience ever since I upgraded to 10.4. I want to have those things NEVER run again, no matter what they're for, preferably by editing a config file because using graphical settings in KDE hasn't actually disabled them.
EDIT: If I kill the process nepomukservices, it keeps coming back! Who does that??? I installed KDE 3.5 now (instead of the very bad KDE 4). I have no setting to disable desktop search, because the brilliant and good KDE 3.5 has no such useless, CPU hogging, feature. But somehow the evil KDE 4 still manages to hog down my system by keeping to spawn this nepomukservices process all the time even when I'm not logged into KDE4 at all!

After upgrading one of my computers to 10.10 I experience freeze on shutdown I understand that there are multiple things that can do that. Is there a way to Isolate the issue. It freezes during the ubuntu dots screen. The dots are still changing endlessly. So it is not complete freeze. The only way to intervene is by issuing a CTRL-ALT-DEL then the computer restarts.

I have no RAID experience on Linux, so I've found dozen of information on the net about software raids, hardware raids and fake raids. Now situation is not clear to me at all. I'm considering to buy one of these cards to run on my Ubuntu server (currently 9.04, but will be upgraded to 10.10):
1. Promise FastTrak TX2300. I believe this is fake raid as it has some RAID bios. It handles SATA II cards and has PCI interface (what is important to me because I don't have PCI-X or PCI-e).
2. Promise SATA 300 TX2 Plus. I believe this could be a software raid because it has no built in raid support at all.
So I don't need to install my system on future raid system I just want to add those disks as storage mirror to my existing system. So what card is better (I believe both are supported on current ubuntu)? Is card better with built in raid which has some settings in BIOS ? What will be setup of the card? I mean should I use any BIOS RAID options or I should disable BIOS raid and use linux dmraid? In that case maybe better choice is card without any RAID in bios ?
Sorry if question is too beginner, but I'm lost with all the information. The main thing I want to know if I should use BIOS raid featured to use fakeraid or I should disable it anyway.

I wrote this script to attach url's to specified 6 digit numbers in a configuration text file. My original goal was to be able to be able to pull the url's and the 6 digit numbers from .csv files. that would allow me to make the script more versatile, not only for this particular project, but also for other projects in regards to the configuration file. This script works, and has served it's purpose, but it is not very pretty, and it's probably not very efficient. What can I do to improve it and possibly make it more versatile. I've thought about functions and arrays, but my skill set is still pretty limited. I'm not looking for someone to write it for me, just to point me in the right direction.

This post is not to ask for help, but rather to document my recent effort to downgrade my ext4 file systems to ext3 file systems. I don't know if it'll help anyone, but here it is anyway, fwiw.I am running ubuntu 9.10 on an older Dell GX-270, and had formatted my partitions with ext4 file systems. I began to notice partimage wasn't backing up my ext4 file systems and I decided to downgrade to ext3 file systems.My system has one 160GB drive and one 500GB drive. I also have an external usb2 500GB drive./home is on the internal 500GB drive. To convert it, I mounted an ntfs file system on the external drive, created a container file, put a file system on it, and mounted the container as a linux file system.
The backup was done done via rsync. rsync makes things really easy. It understands uids, gids, file permissions, and all kinds of links. That's one reason I created the container file on my external drive. NTFS doesn't understand uids gids, linux file permissions, or linux style links.

I have assembled an "old" PC I want to attach to my 32" Sony TV. Mainly for browsing, watching videos, playing casual games. Is there a special Desktop theme suited for big screen ? In other words: Big icons, big text? Not sure if Unity helps out here. I would be willing to install another desktop manager (e.g. XFCE, KDE) than Gnome if it provides such features. Firefox for examples supports increased font size for browsing. For shell I've played around with guake and font sizes around 20 pix. It just would be nice to have "enlarged" menu entries.

I've been looking around for the past week, but I have yet to find anything yet that provides a media center solution using Ubuntu + Xbox 360, comparable to Windows 7 + Xbox 360.
I want to drop Windows 7 completely on my media PC, and just use Ubuntu (or Linux Mint). I've tried ushare, XBMC, Moovida, and a few other apps. Either they don't support sharing, or it's difficult to configure, or it is a cheap looking solution.
Is there no way to use my Xbox 360 for a smooth media center experience, similar to how it functions as a Media Center Extender for Win7, while replacing Win7 w/ Ubuntu?
I'm even open to commercial Linux solutions, I'm just hoping to be able to drop Win7 if possible..

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

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.

I currently have the Ubuntu 32 bit 9.10 installed on my laptop. I wanted to install WinXP 64 bit using VirtualBox. My question is: will WinXP 64 bit run faster on Ubuntu 64 bit than it will run on Ubuntu 32 bit (my current OS)? Is the upgrade from Ubuntu 32 bit to Ubuntu 64 bit worth it for running a virtual Windows XP 64 bit?

according to this article i read, its definitely faster. this is what i read: Since 64-bit systems can process twice as many instructions per second as a comparable 32-bit system, 64-bit systems are definitely faster than their 32-bit counterparts. it was from this article link: [URL]... Is this true? I always thought it wouldnt make a difference, besides more memory addressing?

I put together a p4 that has 3 slots for ddr memory and the specs say maximum memory is 2 G at 400 Mhz or 3 G at 333 Mhz. Now, I assume this means that if you install a third memory stick, it will run at 333 Mhz. Is this right? Which would be better out of curiosity?

I am using Ubuntu 10.10 64-Bit Desktop Edition, and I am looking for a faster way to rip CDs, without having to resort to Windows. I try to rip a CD, but it takes 20+ minutes just to get the files copied, then another 5 or so minutes to burn the cd!I have a new SATA interface CD/DVD burner, so I know it is not the hardware.
