For g,

I’m not sure that you “need” 3 nameservers, however the two outside ones are just backups in case your local DNS is down. So, I would keep them in, just in case your local and the first Outside DNS are both down (which can happen since they aren’t related to each other).

for redtops,

You can try sudo gedit /etc/network/interfaces and see if that will allow you to save the file. I’m not familiar enough with nano or vi or emacs to use those, however I do use gedit (or kdesudo kate) on a regular basis, and haven’t ran into issues yet.

Hope this helps both of you,
Patrick.

sudo nano /etc/network/interfaces

Once your prefered editor opens the file you want to enter the following information (changing your addresses where necessary):

auto lo eth0
iface lo inet loopback
iface eth0 inet static
address xxx.xxx.xxx.xxx(enter your ip here)
netmask xxx.xxx.xxx.xxx
gateway xxx.xxx.xxx.xxx(enter gateway ip here)

Be sure to save your changes.

I cannot save it.

can I know how about this case that a single
PC may have 3 nameservers?

look this internal network
address

[quote]

/etc/resolve.cnf

nameserver 192.168.1.231
nameserver 7.7.7.7
nameserver 7.7.3.3
domain mine.local
search mine.local

[/quote]

i dont get it, why we need to put 3 nameservers there?

I agree with Dave that the Gnome Network Manager seems to randomly pick eth0, eth1 or eth2. On one PC I remember it didn’t always stay eth1.

Back to my previous question - has this been fixed in a later Ubuntu release (picking up a newer Gnome network manager). On the same classroom PC I later used Fedora 12 and did not have any issues with the static IPs.

A word of warning! Before starting, check what your Network Manager has called your wired ethernet connection. The above assumes that it is eth0. Using eth0 on my system did not work. I checked the Network Manager and found that it was using eth1. When I changed the iface entry in /etc/network/interfaces to eth1, it worked perfectly.

This workaround on 8.10 worked for me on one system. Others in my class did not have the issue. As loop says this is not the best if you also want to get on wifi sometimes with same PC.

Is this fixed in 9.10?

Hi,
just to notice some things.
If you edit /etc/network/interfaces so that eth0 would be static like above.

Restarting networking will not give you a static address u put in interfaces.
Because of a problem with network-manager!
Like he is starting dhcp client or something before network script is invoke, it’s realy messy and that’s what is realy bad thing with ubuntu, this problem is old and it’s not fixed yet:(

So, sudo apt-get purge network-manager network-manager-gnome
then, edit interfaces.

Well, if you install network-manager again you will see that it’s not working very well.

But what if you are not advanced user and then you have to connect to wireless network with no gnome manager…problems realy. So “It’s just works” is not a good punchline.

Managed to figure out the issue

I had given “network” instead of “netmask”

Best regards

I managed to install GDM and then ran the package manager during this time the UPS tripped and I did not have sufficient battery so the laptop crashed. I reinstalled Ubuntu from CD and then repeated the steps above to set the static IP. I get the following message

Don’t seem to be have all the variables for eth0/inet
Failed to bring up eth0

Can somebody help me out.

Best regards

Try one of these

Method 1

Create that file using the following command

touch /etc/postfix/main.cf

Method 2

Run the following commands

sudo apt-get remove postfix

sudo dpkg --purge postfix

sudo apt-get -V install postfix

I tried this on Ubuntu 9.04 server. I get the following error when I run sudo /etc/init.d/networking restart

* Reconfiguring network interfaces
postconf: fatal: open /etc/postfix/main.cf: No such file or directory
postconf: fatal: open /etc/postfix/main.cf: No such file or directory

I looked for main.cf in the directory path. No such file existed.

Can some suggest what could be wrong. I need to set this up so that I can connect to the internet to apt-get and install ubuntu-desktop and gdm.

Regards

* Stopping the Firestarter firewall…
…done.
* Starting the Firestarter firewall…
…done.
RTNETLINK answers: No such process
SIOCDELRT: No such process
…done.

OK, after reboot I had to re-edit /etc/resolv.conf and put the name servers back as it dumped the info.

By: bob

bob — Tue, 23 Jun 2009 18:35:38 +0000

Under Ubuntu 9.04 I simply disabled Network Manager from System|Preferences|Startup applications. Edit the two files as suggested and reboot and the PC came up answering at the new IP.
