No networking on Ubuntu 6.10

[sculptor]

I have installed Ubuntu 6.10 AMD64 on an Opteron based PC and Im having problems getting the network up and running.
The install went smoothly and I checked that the network connection was working and it was.
I was about to set up a new user when an info bubble popped up and asked if I wanted to download and install the new updates.
I clicked on the update icon and it downloaded and installed the updates and asked me to click on the update icon to restart. I clicked OK to restart and when it opened back into the desktop I tried to connect to the network it couldnt.
I did write down the network settings before updating but if I try to use these I still cant connect.
The PC is connected through a router as are all my other PCs running XP.

what do you get from ifconfig, can you see eth0 details?

 

[deano]

can you also cat /etc/resolv.conf and post contents up here, also dmesg output. dmesg >dmesg.txt will give you a txt file in the current directory.

Im completely new to linux, how do I get the ifconfig?
Do I use a termial window to do this?

 

[deano]

yep

You might also want to try pinging your router or pinging your Ubuntu machine from another machine on the network. That would indicate what sort of problem you have if the ping is successful yet you still can't connect to the Internet.

ifconfig gives me the following:

eth0 Link encap:Ethernet HWaddr 00:01:295:19C
UP BROARDCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0

RX bytes;0 (0.0 b) TX bytes:0 (0.0 b)

lo Link encap:Local Loopback

TX packets:1142 errors:0 dropped:0 overruns:0 carrier:0

RX bytes:57100 (55.7 Kib) TX bytes:57100 (55.7 Kib)

It should be a capital d where the smilies are.

Tried to ping from Ubuntu to my router and get nothing.

if your network runs DHCP try:-

sudo /etc/init.d/network restart

if your network runs DHCP try:-

sudo /etc/init.d/network restart

Just tried it and I get "command not found"

 

[BillytheImpaler]

use
sudo /etc/init.d/networking restart
instead. It just worked for me.

Thanks Billy, typing this on the Ubuntu PC.

Woot!

Now, on to finstalling.

I recommend you set a static IP and install SSH right off the bat so you can remotely administer the macine from any other machine, including one running Windows. It makes it handier to monitor a farm that way.

Not quite there yet!
I tried a reboot (just incase when running F@H) and the network failed again.
using the command sudo /etc/init.d/networking restart has got it working again but as you know it needs to work all the time.
Would setting a static IP address solve this?
And what IP address should I set?
Soz for being a noob at this.

Heck if I know. It can't hurt to try.

I usually set the static IP to be the same as the one DHCP gave it. If you're in Gnome open up System >> Administration >> Network Tools and find your IP address. Then open up System >> Administration >> Networking and click Properties for your Wired connection and set the information. Reboot and see if it works.

My IP Information is:

IPv4 127.0.0.1 255.0.0.0
IPv6 ::1 128 Host

The second one is highlit.
Not sure which one to use.

 

[sculptor]

When I click on Networking or Network Tools I am not being asked for my password is this normal.

 

[BillytheImpaler]

That's your loopback IP. You need to change the Network device drop-down to Ethernet interface to see the status of that Ethernet interface.

EDIT: Yes that is normal.

i would recommend using an IP that is not in your DHCP range, to avoid problems later on.

If I set it to static entering the following IP: (this is the IP shown with eth0)
IP 192.168.1.107
Subnet mask 255.255.255.0
the connection dosent work.
Do I need to enter a Gateway address aswell, if so would this be the routers name.
