Hello everyone!

I have just set up a new server and installed the latest version of the Ubuntu Server edition onto it. Now I'm having technical difficulties (typical). Ughh. So I'm in need of desperate help.

Okay, so the big problem that I'm having is that I'm unable to connect to I believe anything outside the computer. I tried using commands to update, and commands to get a GUI on the system, however, they all just fail (in other words I notice the word "fail" multiple times). I attempted to change the /etc/network/interfaces file, and this is what I put in:

iface eth0 inet static
address 192.168.122.0
netmask 255.255.255.0
network 192.168.0.70
broadcast 192.168.0.1
gateway 192.168.0.1

I believe the original file had none of the options listed, and static was replaced with dhcp, but up above is the CURRENT status of that file.

and the /etc/resolv.conf file looks like this:

nameserver 192.168.0.1

Then when I do the command: sudo /etc/init.d/networking restart, I get this:

* Reconfiguring network interfaces . . .
SIOCADDRT: No such process
Failed to bring up eth0.

And something tells me that that isn't right. I obviously can't even connect remotely to this server via PuTTy on a Windows Vista machine. And I tried to ping google, and it couldn't find the host. I'm figuring that I entered the wrong numbers up there in the interfaces file, but I'm not sure where to find ANY of those numbers :-o It's driving me insane!!!!!!

Oh, and I have the server directly connected to a Motorola 3347 Qwest router thingey, which is also connected to the Windows Vista machine, and wirelessly connected to a Macintosh.

Any help and guidance would be much appreciated!! I'm sorry if I'm just being stupid or something, this is my first time attempting to set up a server, so it's all kind of new to me.

I'll move you over to where the Linux folks live.

Hi Hal356,

First things first - i.e. setting up a server requires planning aforethought which appears to be lacking in this case, so your experience is not surprising. Setting up a server is a lot different than a desktop.

Starting from your router, it needs to be able to identify each computer on your network by a unique internal network address, and each computer needs to be able to identify the router by the same unique internal network address, i.e. one-to-many and many-to-one relationship. For instance, I have a hardware router with only one computer connected to it. My router's internal ip address is: 192.168.1.1 and my computer's internal ip address is 192.168.1.2 - very simple.

That said your internal network is more complex and you need to sort out what your other internal network addresses for your other computers are first, so that you do not name your Ubuntu server with an already in-use internal ip address as far as the router is concerned. One thing you may be able to do is to login to the router as admin if you have the admin password and the router's documentation. Then you can inspect what computers it may have connected, and be able to address what internal ip address is available for your Ubuntu server.

Your netmask of 255.255.255.0 appears to be fine. Try a broadcast value of 192.168.1.255. Try a nameserver in your /etc/resolv.conf file of: 192.168.1.1 and try gateway of 192.168.1.0 - assuming that 192.168.1.1 is the internal ip address of your hardware router on all computers of your internal LAN.

Check on your Windows Vista with the ipconfig command what your internal settings are - to the extent that it will tell you. I do not know which Mac you use, but if it is OSX, then it is probably like Unix so try the ifconfig command.

Hey, thanks man.

So I know I'm being the Ubuntu Server Dunce. Haha. Can you show me exactly what my files should look like? I think I'm putting in the wrong lines none the less.

So yeah, if someone can just tell me what the file is supposed to look like I won't have too many issues, and we can pinpoint the problem (if there is one) more efficiently.

And if I need more information, please let me know.

Once again, I apologize for being the dunce of the Ubuntu Server.

[arochester]

and commands to get a GUI on the system

Ubuntu Server doesn't have a gui on the CD...

Have you looked at e.g. http://howtoforge.com/set-up-ubuntu-...p-dns-ftp-mail ?

[Hal356]

Yes, I know there isn't a GUI on the CD, I was trying to get the GUI off the internet but as you can clearly see I failed, unfortunately

[lotuseclat79]

Hi Hal356,

As arochester recommended, download and install the Easy Hosting Control Panel and follow the directions on the 3 web pages from the link he posted - it does tell you what your files should look like - so, if by now, you have not looked at those web page(s), you should do so with all haste to help you solve your problem.

arochester posted link: Set Up Ubuntu Server With EHCP (LAMP, DNS, FTP, Mail) (3 web pages).

EHCP link: Easy Hosting Control Panel. Click on Download link in the left-hand side panel and follow directions to download.

[Hal356]

Yes, thank you.

When I was starting the server update. I googled this page and followed it with careful precision. And yes, I got stuck on page 2 where it tells you to change the to Static IP, and I didn't know where I needed to find the numbers to put on there. And I just need to get past this part AND I WILL BE GOOD! I can clearly follow the directions on how to set up the rest of the server if I can just figure out this one little part. Like here is a quote from the beginning of the tutorial: "You will need to know the ip address you want to assign to the server, it's subnet mask, the default gateway and the ip for the dns server." and I need someone to tell me these numbers! Then I believe that if I follow the rest of the tutorial that I should be perfectly fine.

May you tell me the numbers I will need from above to setup the interfaces file, and what can stay, and what needs to be changed? I'm sorry if I'm being an idiot or something.

Thank you.

There are no error messages that appear now. All it says now is * Reconfiguring network interfaces . . .

However I am still unable to move onto the next step with the command apt-get update. It always ends with a long list of files that were unable to be retrieved.

[lotuseclat79]

What is the content of your /etc/network/interfaces file, i.e.
$ cat /etc/network/interfaces

What is the output of the ifconfig command:
$ ifconfig

On your Mac and/or Windows, what is the output of your ifconfig/ipconfig commands?

Exactly, where are you stuck on page 2?

-- Tom

[Hal356]

This is the content of the /etc/network/interfaces file:

# This file describes the network interfaces available on your system
# and how to activate them. For more informations, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet static

netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
gateway 192.168.1.1

The above is the contents of the /etc/network/interfaces file, and the output for the ifconfig is listed below:

eth0

And I am stuck in step 3. Install EHCP, I am right where you are supposed to type the command to get updates:

$ apt-get update

When I type that in, the output for a little while is 0% with some addresses near that percent, and after a little while, the rest of the output is basically like an off screen list of "Files that could not be Fetched".

Here is the ipconfig/ifconfig outputs for every other computer on the Network:

Hi Hal356,

First, let's test your network TCP/IP stack to see if it is working properly. Issue the command on the Ubuntu server aka ping the loopback address:
$ ping 127.0.0.1

If you can successfully execute this command, then the TCP/IP stack of your computer can talk to itself allowing you to rule out the Linux environment as a source of trouble.

Just as a curiosity on my part, try to ping the router, i.e.
$ ping 192.168.1.1

Next, try to ping the server's ip address (from itself) which you have setup as 192.168.1.254, i.e.
$ ping 192.168.1.254

If you can't ping the Ubuntu server's internal ip address then there might be a hardware error message that occurs on bootup with the network card - and you might have to run the network card diagnostics that came with your network card. Run the following command, i.e.
$dmesg | less
and check for problem messages.

Next, try to ping the ip address of another computer on your LAN, i.e.
$ ping 192.168.0.83
for the Mac, and for Windows Vista
$ ping 192.168.0.70

If you can ping the other other computers on your LAN, then the computers are functioning correctly at the data link level, if not then there is a data link level problem.

Also, try the inverse, i.e. from the Mac and Windows Vista computers, try to ping the Ubuntu server computer, i.e.
$ ping 192.168.1.254

Your /etc/resolv.conf file should contain at least(and your router should be setup to use the default DNS servers (primary, secondary) of your ISP provider in order to resolve Internet addresses):
nameserver 192.168.1.1

I have my router setup to use OpenDNS servers. Consult your router's documentation on admin login (don't forget to change the default password and remember it), and try to change its DNS servers for your WAN (Coax, Wireless and/or Ethernet):
208.67.220.220
208.67.222.222

What results did you get in each case?

Hmm. Well, the only thing I did that was successful was testing the Network TCP/IP Stack:

$ ping 127.0.0.1
29 packets transmitted, 29 received, 0% packet loss, time 27993ms

64 bytes from 127.0.0.1: icmp_seq=1 ttl=64 time=0.029 ms

Everything else I attempted to do appeared to fail. When I attempted to ping the Router and the Server IP Address I got these errors:

connect: Network is unreachable

When I did the dmesg | less command, there was a HUGE text file that I had no idea what to look for in it.

When I attempted to ping the server from other computers, it appeared to send packets, however there was 100% packet loss.

I'm beginning to think this is a hardware issue now. Do I need to install an Ethernet driver for my Linux Server?

Here is my status of the router and all of it's information. When I attempted to change the router to static IP addresses, I lost my internet connections.

Hi Hal356,

Ok, it looks like your internal network router ip address is 192.168.0.1 instead of 192.168.1.1, so, that should tell you that you should run the command:
$ ping 192.168.0.1

Try following the advice in my previous message and let us know what happens?
