Hi to all,
i just installed
Red Hat 5 Enterprise
Kernel ver: 2.6.18-8.el5
Ethernet controller: Marvell Technology Group Ltd. 88E8053 PCI-E Gigabit Ethernet Controller


and i can't connect to the internet through the ethernet interface.

I have configured manually the ip, netmask and gateway.

the ifconfig output is :

----------------------------------------------------
eth0 Link encap:Ethernet HWaddr 00:16:E6:5B:8B:56

tnx a lot for help

Have you looked at the lights on the card? Have you looked at the hub, or switch where the server plugs in? What is the status of those lights?

Link is down... Should be "UP ... RUNNING ...". It's not. verify patch cord

If you can ping the gateway your network adapter is working correctly. If you can not ping google but can ping 66.102.9.103 successfully then all you need to do is add a name server to your /etc/resolv.conf file. DHCP automatically updates resolv.conf but not when you manually configure the network.

if i link the cable to my laptop it works.

Unfortunately there is no led going outside the case (i can't open it )

No, i can't ping anything (Destination Host Unrichble)

It can be a driver problem??

thx for all the suggestion.
I do my best but nothing seems to change

however i'll keep trying otherwise my advisor kick me in my a**....

You should have used RHEL 5.4 DVD, not 5.0. It this RHEL even legal? If it is, then add additional PCI NIC (Realtek 8139 is the best for linux support) and update the system. If I remember correctly there could have been the problem for Marvel NIC's of 5.0 kernels, but was resolved later on.

If you have not paid for RHEL, then better use CentOS, it is in almost any way the same thing but CentOS is free of charge.

Yes it is legal (My boss has paid it...), Unfortunately I could use only RHEL 5.0 DVD

I don't think i can add it

I have to use RHEL sorry.. These are the top words!

If you can not add any kind of NIC to download updates, I think you can request from Red Hat 5.4 media (DVD) and reinstall it.

What is the output of the command:
route -n

Is ur lan card is ok or not?u must clearify it first.if u sure it ok.then setting ur ip address and u must run this 2 commands-
1.service network restart
2.chkconfig network on.
then check that u get internet or not.if not u just run this 2 commands also-
3.ifdown eth0
4.ifup eth0
now u check u get ur service or not?

thanks

Maybe, but chances are it isn't.

If you've already followed the advice of others here, and checked the patch cord, looked at the card to see if you've got activity lights, etc., you're a good part of the way there. First, verify with your network admin that your netmask and address are correct. A "Destination Unreachable" could very well be that you haven't configured a default route, which you can also get from your network admin. To test this, see if you can ping another address on the same network. Based on what you posted, it will be something like 192.168.100.xxx. If you can ping something else there, it's a gateway issue. Try:
Then see if you can ping something on a different network. And as others have mentioned, the DNS resolution needs to be configured too, so you can ping by hostname.

Please don't post things like this. It's impossible to read and understand, and will NOT fix the OP's original issue. All this is doing is starting network services. If the driver isn't loaded, this won't do it. If it's not configured right, this doesn't address it. This is pointless for the OP to try.

hlo,

maybe I'm completely wrong, but is it possible to upgrade the kernel in that distro...?

I think your ethernet-card is newer than the kernel, so that's maybe a reason it doesn't work...
(I've had the same thing in PCLinuxOS 2009 with a new laptop (Marvell Ethernet card was completely dead in linux), had to install a more recent kernel (downloading it on another computer and install it via the kernel...)
=> or did you install that distro previously and worked that card at that moment?

If you can't upgrade your kernel (and if that's the problem) in RHEL 5.0, try then another distro (like CentOS indeed)

Hope this helps
