Hello everyone,

I need help with a big networking problem I am having. I just installed a trial version of RHEL 6 on my computer. Already in the installation process I noticed something weird - during the install process, there is a stage where you can choose to configure the network now...that button was grayed out and there was nothing I could do about it.

Once the installation ended and the computer booted, there was no network. If I try to go to /etc/init.d/network, or NetworkManager - it doesn't exist - it gives me an error saying "lines such and such pertaining to network (dont remember the numbers) do not exist in /etc/sysconfig - i.e., there is no network configuration whatsoever.

I have no idea what I can do about this - I think maybe RHEL is not recognizing my network card? How can I know if this is the problem? And how can I solve it?

I have two hard drives in this computer, in one, I have an Ubuntu installation, in the other, I have the RHEL.

This is the info about my network card which I took from the Ubuntu install (which has networking working 100%, out of the box, no extra config needed) - I have regular ethernet card and a wireless card, both in the motherboard:

sudo lshw -class network

Any help is highly appreciated!

if you are NOT going to buy the REQUIRED support license
you will not be able to install any software ( other than on the outdated dvd)

use CentOS 6.3
also cent added a bunch of programs FOR DESKTOP use
RHEL was not meant for use on a home desktop ( it can be , but was NOT designed for it)

buy the rhed license
( and if you have to ask then you WILL need the $299 per year license )
https://www.redhat.com/apps/store/desktop/


then read the red hat install documentation '

https://access.redhat.com/knowledge/...erprise_Linux/


for the network RHEL is very MANUAL there as almost no automatic anything
YOU will need to manually set it up ( cent has some automation)

Hello John VV,

I am currently studying for the RHCE certification and in my course, I was given this one month trial DVD, which I was told should be ok to install at home (for the certification studies purpose) - so you say it will not work unless I buy the license and/or install CentOS 6?

I did install from this same trial DVD on a vm machine (on a different computer, which I no longer can use) and it worked fine, so I am guessing the problem is not with the DVD, the problem might be that RHEL currently does not support my specific network card?

Thanks again,

unless you buy the required license ( $49 to $299)
you do not install anything that is not on the "out of date" dvd - NO current security updates
RHEL 6.3 is the current ( 2012-06-20)

if you have a rhel6.0 it came out on "2010-11-10"
and is two years ( almost) out dated

if you ARE taking the RHCE
BUY the red hat license and you also might want to buy the red hat books and testing tools for the test

thought you could "get away" with installing CentOS 6.3 .
You will get NO experience using red hat's RHN
Nor any experience in registering a red hat install

also if you buy the required license you also get access to the redhat knowledge base
( some is open to the public- but only a small part)
https://access.redhat.com/knowledge/search


or port the CentOS wiki for use on RHEL
http://wiki.centos.org/

Hi John VV,

I bought Michael Jang's book and am using it to study.

Not sure I understand what you meant by "thought you could "get away" with installing CentOS 6.3 .
You will get NO experience using red hat's RHN
Nor any experience in registering a red hat install" ?

Also, regarding that specific network card problem, it doesnt seem to be related to the outdated trial version, I read in several places, from people who did buy a license and had the same problem with lack of support of broadcom network cards...so even if I buy the license, I will still encounter this problem and need to solve it :-(

Thanks again,

kmod-atl1e
is the driver needed
and it will require a paid for license to install it on RHEL6
buy the license
or install CentOS

you might want to plug in a cable connection

it is also in the elrepo repo
http://elrepo.org/tiki/tiki-index.php
but without a paid for license
that might not work


or direct download
http://elrepo.org/linux/elrepo/el6/x86_64/RPMS/

but on a unregistered copy of RHEL
you will have fun
you can try( no idea if it will work ???? )
download the rpm ( firefox can install it directly from the web page )
or
save to to your home folder and double click on it
and use "the package manager" to install
or

OK, thank you very much for the information, I will follow your advice and let you know how it goes.

Thanks!

Hi John VV,

After much thought, I decided to switch from the RHEL trial version to CentOS - installed it and it recognized my network card right away.

I hope I will manage to study with centos just as well as I would have with the original RHEL.

Thanks for you help,
