Internet Slow – What to do ?

Posted on by

Got call from customer saying that their Internet is slow and sometime drop out. And wanted to have a check. Well for case like this, I would suggest best to go and approach the ISP (You service provide) as more then 60% is due to the Service provide doing some work on the Exchange end or mis-configuration. And they are able to resolve it in very short time. But by getting us down, we still assist you to liaise with your service provide to resolve the issue. Which in the end you actually pay something extra. Although i charge min for that sometime but still incurred some cost in your monthly expenses. As we can’t go down without a basic fees or do it FOC because of the time spend. So is best to check the ISP and make sure isp acknowledge that nothing is wrong in their end and something is wrong with the PC before giving us a call.

Change Ubuntu Server from DHCP to a Static IP Address

Posted on by

Ubuntu Server after installation has set your server to use DHCP. you will need to change to a static IP address so that people can actually use it.

How to you change without using GUI.

  1. 1.Changing this setting without a GUI will require some text editing, but that’s classic linux, right?
  2. Let’s open up the /etc/network/interfaces file. And use vi, but you can choose a different editor

sudo vi /etc/network/interfaces

 

  1. For the primary interface, which is usually eth0, you will see these lines:

auto eth0
iface eth0 inet dhcp

 

  1. It’s using DHCP right now. To change that you need to add a number of options. Obviously you’d customize this to your network.

auto eth0
iface eth0 inet static
address 192.168.1.100
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
gateway 192.168.1.1

Now we’ll need to add in the DNS settings by editing the resolv.conf file:

sudo vi /etc/resolv.conf

On the line ‘name server xxx.xxx.xxx.xxx’ replace the x with the IP of your name server. (You can do ifconfig /all to find out what they are)

You need to also remove the dhcp client for this to stick (thanks to Peter for noticing). You might need to remove dhcp-client3 instead.

                      sudo apt-get remove dhcp-client

 

Now we’ll just need to restart the networking components:

sudo /etc/init.d/networking restart

Ping www.google.com. If you get a response, name resolution is working(unless of course if google is in your hosts file).
