Comments on: Change Ubuntu System from DHCP to a Static IP Address

Can someone help with the following please :

Set up LAMP sever on ubuntu 11.04 . Localhost gives home page with no problems
Altered the server /etc/network/interfaces file to show
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
address 192.168.0.5
netmask 255.255.255.0
network 192.168.0.0
broadcast 192.168.0.255
gateway 192.168.0.1

Performed sudo /etc/init.d/networking restart

Configured my Sky router so that port forwarding HTTP port 80 sends to ip address 192.168.0.5

Then checked to see if could connect from internet using a tool on http://www.dyndns.com/support/tools/openport.html and input the ip address showing on my ADSL port ip address. Results give “An attempted connection to 94.0.47.254:80 was refused. This typically indicates that there are no services available on that port, but that it is NOT being blocked by a firewall or your ISP”

What have i done wrong ?

My /etc/network/interfaces only mentions the LO network. Configuration of ETHx and WLANx seems to be buried inside of WICD (or net manager) somewhere. Am I supposed to edit this file anyway?

Also, if I do this, any and all DHCP is no longer available for those times when I’m gone walk about with my computer. Isn’t there some sort of “situation manager” that will enable, disable, configure and change settings based on some name token that identifies where I’m trying to do networking?

Nice article. Clearly written.

Also don’t forget to edit /etc/resolv.conf and add your DNS nameservers there, as you are not getting the DNS configuration via DHCP anymore and your machine is probably not resolving any hostname. Just add lines of the sort:
nameserver 1.2.3.4
nameserver 5.6.7.8

FYI:

“network” and “gateway” is usually the same, where the router is connected to the pc/mac.

However, if you have a router connected to a router and it is connected via Ethernet cable and the following is true:

- Disabled DHCP in the router and the server (for noobs, DHCP automatically assigns IPs to machines like pc and printers etc.)

- Assigned static IP within your network.

- you recently installed Ubuntu on your pc and is using wireless to connect to the router for internet.

If the above is true, then the “network” should be the IP address you have set for the server. Then the gateway (which is the router in this case) will have the router’s IP address.

Hope this helps somebody, somewhere.

By the way, thanks to admin (left message here on Aug 25, 2010 at 5:54pm), Jordon Bedwell (Sept 20, 2010 at 1:50am) and alexanderhspencer (oct 21, 2010, 2:08am) that helped me understand the above article.

note:
for me, i put the “network” and the “gateway” feilds as the same ip address as my router (in windows called a default gateway)
and it worked a-ok!
“address” refers to the ip address that i want to assign to my computer. i have no idea what broadcast is but it is always the same.
thanks,
alex

:wq! is incorrect, it will ignore any errors and “force save” so if you don’t have permissions you would never know as it would just exit. You need to do :wq without the “!”

press Esc and :wq!

This will save and quit your file

Using Wicd was an excellent tip. Lovely little utility. Thanks.

For those struggling with network-manager. Just remove it.

sudo apt-get remove network-manager

I cloned the recipe and tried it… only to find out that I can no longer reach the network. Then I added the lines
dnsserver X.X.X.X
to the ones above, and the static IP worked
thanks a lot

Your device must coexist with other hardware and applications. ,

It does not work with wifi DNS router.

Worth mentioning here is that you can specify the DNS server IP#s from opendns.com in /etc/resolv.conf if you want. Alternately, you could leave the nameserver IP# in /etc/resolv.conf as your router’s IP#, and using static DNS server IP#

I have found opendns.com’s DNS servers to be much faster than many ISP’s, and my ISP would typically do service on their DNS servers over the weekend and our home router and it would be slow in relaying the changing DNS server IP#s

Leave “auto eth0″ but disable it.

Create a new wired with the MAC from “auto eth0″ and all info.

I had some trouble getting the settings to work,
the error I made was to omit the line “auto eth0″, it is essential!
The lines network and broadcast can safely be omitted, they are calculated automatically from the address and netmask values.
