Is this a wired or wireless card?
Please open a konsole and run the command 'ifconfig -a' and post the results.
If it is wireless, also run the command 'iwconfig' and post.
It would also help if we knew if a kernel module is loaded, so please run '/sbin/lsmod' ( all commands with out quotes ) and post the results.
A description of your network hardware would help, router make and model etc.

i think that this NIC is not supported with the kernel ;
since my router ip is 62.139.120.193 and DHCP is enabled ;

Here is what I have found.
Quote:

LAN Realtek RTL-8100C Standard network chip, works fine with the kernel 8139too driver (possibly 8139cp also?)
|
So the card is supposed to work. I don't see that module in your lsmod output, however since the card is recognized, support must be in
your kernel.
Some things to try. Use ifconfig to set a fixed IP address, try to ping your router. You probably need to add a default route as well.
You could also run a dhcp request from a konsole, and see what happens. See if it gets an address added with ifconfig. It will show up on
line two of the ifconfig output. The command is run by root, 'dhclient'.
I guess we should also verify the cable from the ethernet card to the router is good. If you have a spare, swap it, or just test this one
on another system. There should be a green led on the ethernet connection ( or on the card ). It should be on and bright green. Also have
a look at your router port where the cable is plugged in. These lights vary a little from router to router. Usually there is one green light
for connection and one for activity. Tell us what you see.

Right well I don't know a great deal about your particular card, config or even Linux distro but a couple of things do come to mind.

Seems an inadequate command to me.
Don't you need to supply a subnet mask?
Don't you need to tell the command if you want to take the interface up|down?
As in:
Code:
ifconfig eth0 10.0.0.1 netmask 255.255.255.0 up

No DHCP offers received.
You sure your router is configured as a DHCP server?
You sure the Linux box doesn't have security or firewall ports blocked preventing receipt of a DHCP offer from the router?

The fact you get a 169.254.5.43 addr on one of your eth0 configs would appear to confirm the lack of receipt of a DHCP offer.
(169.254.x.x addresses are knows as APIPA or automatic private IP addressing, and are assigned to Windows clients when they can't see a DHCP server.
http://wiki.networkdictionary.com/in..._IP_Addressing)
Not sure about Ubuntu distro, but on CentOS (RHEL look-alike) I'd expect a file:
/etc/sysconfig/network-scripts/ifcfg-eth0
to have content like:
Code:
# more ifcfg-eth0
DEVICE=eth0
BOOTPROTO=dhcp
HWADDR=00:aa:bb:cc:dd:ee
ONBOOT=yes
TYPE=Ethernet
to configure the NIC on boot.
And in fact if you have /etc/sysconfig/network-scripts/ifcfg-eth0 configured correctly you'd only need to use the commands:
ifup eth0
or
ifdown eth0
to bring the interfaces up|down.
I'd recommend taking a look at http://www.linuxhomenetworking.com/w...nux_Networking: it's a very useful read.
Hope that helps. This all assumes the HW, cabling is OK and working (but since you get connectivity with MSWindows that would appear to be the case). |

eramax,
After reading through your posts, there are some things to fix, and clear up.
You have a router. The address your ISP sees is '62.139.120.193'. This is a class A address. ( not private ) Your home lan side should not be using
addresses in this range. Usually routers will use a private class A, B, or C address range. For class C it is usually 192.168.xxx.yyy with
a sub net mask of 255.255.255.0. You can if you want, use private class A 10.x.y.z.
Routers translate the private IP addresses on your lan side to one public IP address on the ISP side. So if you were to use a
class C private range, like 192.168.0.xxx you could have 254 systems attached, all connecting to the ISP through the public address.
It makes no sense to use a public address on your side.
I saw you tried to add an IP address. I don't think you had the command right. Form the man page;
Quote:
|
ifconfig interface [aftype] options | address
|
So to set an ip address, 'ifconfig eth0 192.168.0.10' would set an IP address ( class C private ) to 192.168.0.10. The mask will be
the default class C of 255.255.255.0 if you do not specify it.
Would you post some information about your router? Make model etc. Have you looked at the router configuration?
The dhcp request failed, we need to look to see if DHCP is enabled, and what range of addresses it will hand out. This is usually
configurable.
I had a closer look at your lsmod, you do have an ethernet driver loaded. It is Nothing is using it. note the 0 at the end...
Could you run the command as root 'ethtool -i eth0' and post the results. This should tell us what driver is being used.

After Rebooting the system another time ,the internet was not running and i can not access any site or even the router from my browser or all browsers on this dist ;
i feel bad from that ,i have alot of days very sad about that ;
i think thier is a problem in configuration or it is not completed ;
when i reboot the system and after login i think the system tries to get ip from dhcp which then stop the internet because the ubuntu have a problem with this dhcp (dhcp is enabled on router )
but what about pinging on router that seem that when i added this route to ubuntu ,it can access it but not uses it as a gateway ;
i want to say also when first time i run the liveCD of this dist on this new computer ,i was enabled to access internet without any problem without any configuration without any thing;
but after rebooting i couldnot;
i tried to run the LiveCd alot of time to see if i can access internet with it ,but i could not accesss internet ;
the internet run on my Linux dist in random ;
i hope thier is a solution ;
thanks

eramax, camorri has given you a heap of good advice (e.g. public vs. private IP addresses) and asked you do a couple of things like post the router make, model, config details and the output of the ethtool command but you're not providing the requested info.
Until you respond to some of the questions this is just going to continue floundering around.
I have no idea why you would need to be adding routes to ubuntu if you are using a standard home router with DHCP server - completely unneccessary.
I'd expect to see something like
Code:
#route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.1.0 * 255.255.255.0 U 0 0 0 eth0
default netgear-router 0.0.0.0 UG 0 0 0 eth0
#
showing a clear route to your gateway (namely the router) and none of this public address stuff; and all that is dished out by the router/DHCP with no Ubuntu configuration (provided you're using a SOHO router which you have not yet confirmed/denied).
More (of the requested) info please!! |

Code:
eramax@eramax-desktop:~$ ethtool -i eth0
driver: r8169
version: 2.2LK
firmware-version:
bus-info: 0000:02:00.0
eramax@eramax-desktop:~$
and i am not the owner of this Lan so i can not change the configuration of the router , i was running on it under this dist before on my last computer and i worked two years without any problem;
so i thinks the problem not in my Lan or router , the problem in my configuration of my NIC ;
my router model is conexant and i takes two pictures of its control panel ;

I understand the router LAN config is not under your control.
I am however slightly mystified by the config pictures you posted as the first shows a WAN addr starting 41.xxx. and a LAN start 62.xxx. and then the second shows a LAN of 10.0.0.x subnet address range and yet you are not configuring your Linux box to just acquire the 10.0.0.x by DHCP from the router, i.e. why you do the ifconfig eth0 62.139.120.193 netmask 255.255.255.0 up stuff, I don't understand.

I think I'm having a similar problem with my Realtex RTL-8169. The symptoms are identical to the previous poster. One thing I'd like to add is that I ran tcpdump on another machine on the network.
00:15:59.244172 IP 0.0.0.0.bootpc > broadcasthost.bootps: BOOTP/DHCP, Request from 00:18:e7:08:32:c1 (oui Unknown), length 300
00:15:59.245229 arp who-has 192.168.1.101 tell 192.168.1.1
00:16:00.273527 IP 192.168.1.1.bootps > broadcasthost.bootpc: BOOTP/DHCP, Reply, length 548
so the request is being issued, and the router is responding, but dhclient quits saying "No DHCPOFFERS received"
I'm going to try swapping out the NIC with another as the eramax has done. I'm a bit skeptical that it will have any effect, as I have been running windows xp on the machine for months without issue.
