Did you solve your slow Internet connection on Ubuntu 8.1?

Recently I am facing a slow Internet connection problem on my newly installed Ubuntu 8.1.

Let me describe the problems first:

During the first couple days of using newly installed Ubuntu, I have no problem and the Internet is as fast as in Vista. But after a couple of updates, the Internet speed changes dramatically. As I noticed the mainly change is the browsing speed not the download speed. It needs at least 1 minute to open gmail.

I tried several methods to improve the browsing speed, like disable IPV6; switch to another browser,like Opera,Swiftweasel; install dnsmasq and change the MTU value; as suggested but none of them work on my case.


Untill today, I find a solution from http://www.prash-babu.com/2008/04/how-to-configure-dns-servers-in-linux.html

It really works for me, so I want to introduce it to you, if you are facing the same problem like me. Why not try?

Do the following steps to configure DNS servers in Ubuntu:

Step 1:Go to Applications->Accessories->Terminal and type
sudo gedit /etc/dhcp3/dhclient.conf
Step 2:Go to the end of the file and add the following line to the END of the file
prepend domain-name-servers 208.67.222.222,208.67.220.220;
Step 3:Save the file and close it.
Step 4:Use the following command to restart your network
sudo /etc/init.d/networking restart

Step 5: Open your favorite browser to check whether works or not.

Install VMD on Ubuntu

1. Register and download the suitable version of VMD from http://www.ks.uiuc.edu/Development/Download/download.cgi?PackageName=VMDLINUX
In my case I choosed:
AMD64 OpenGL (Linux (64-bit AMD or Intel EM64T x86) with hardware OpenGL)
2. Open downloaded package and check the configure file, and make sure that the installed path is: install_bin_dir="/usr/local/bin".
3.In terminal type in
./configure
cd src
sudo make install
4. after finish, type in vmd in terminal to check whether you can run it. In my case I got an error something like: bash: vmd: /bin/csh: bad interpreter: No such file or directory
If you have the same error you probably also need install csh from Synaptic Package Manager.

1)To install csh: go to synaptic package manager, type in csh to find csh related package
2) right click and choose "mark for installation". Then apply.
Then you can try again in the terminal by typing vmd.

2. Use OnyX change the parameters of the finder to show hidden files on your Mac.
3. Locate and copy binary files unrar and rar to your bin folder (Macintosh HD/bin).
4. Change the finder parameters back to hide the hidden files.
5. Suppose you have a folder named “EXAMPLE” want to compress.
6. Launch terminal and go into this folder “EXAMPLE” and type

rar a EXAMPLE

And a rar file named EXAMPLE.rar will be in the folder after finish.
7. You also can compress the file into specific size by using the -v parameter,

rar a -v[size] EXAMPLE

Here the size is in KB
8. Use the following command to uncompress a compressed file:

unrar e EXAMPLE.rar
