General :: Not Able To Connect To Internet In RHEL 5 / Enable This?
May 24, 2010
I just installed red hat enterprise 5 in my laptop and on desktop both. In desktop it is working fine but in laptop it is not showing the eth device. (I tried ifconfig only lo is there). I tried ifup eth0 still nothing happened. The network service in /etc/sysconfig/network-scripts/ifcfg-eth0 and in /etc/sysconfig/network are enable. I had ubuntu in my laptop before and I faced same problem with that too. Is there any problem with my laptop? I have my system on dual boot and in win7 networking is running fine. I am not able to connect to the internet only, other devices are working fine.
System conf: Sony vaio E series. 3 GB RAM, intel core i3 2.13 GHZ.

I don't know if i should of put this in either Networking or Dell Forum. But here goes. I have a Dell Studio 1535 Laptop, and i have downloaded the new ubuntu 10.04
The problem is, is that i cannot get a internet connection. On my laptop there is a wifi sign that lights up if it works, and it didnt when i booted it. So i thought i have the driver downloaded and i tried to install it and it installed but after it crashes, so that failed. And then i tried via Ethernet and it does not connect when i connect it to the router!. It just says disconnected everytime .
I have tried to reboot, just incase it was a bad boot or something, and i stil get the same. It just will not connect to the internet

I recently installed Ubuntu 9.10 on my Dell Inspiron 1545 64-bit laptop. Before that I used Windows7. In Windows, the internet connection worked perfectly well. But after installing Ubuntu, I am unable to connect to the internet. The network-manager applet finally says that "You are disconnected". When I do the "ifconfig", I got no IP address.
So, I installed Ubuntu 9.04 in the same system. But the problem persists.
I gone through many posts in this forum but nothing was useful.

I installed RHEL 5 today and set my network. Did it as follows:Eth0 connectionPrimary DNS 192.168.1.1When I click on Activate, it says:8139too device eth0 does not seem to be present, delaying initialization.This message shows no matter how many times I log out or restart.I don't know what the heck is the problem. I've done the essentials but still it's not working. I looked up on the net but people were saying things like ifconfig and lspci, and at the end still weren't able to solve it. I don't know all this since I'm new to Linux. Another important thing...after facing this same problem some time ago, I installed Centos which asked for internet settings right at the time of installation. And after logging in for the first time, I was able to use internet without any problem. How come internet works on Centos (which is a copy of RHEL) without any problems, but not working on RHEL itself?

I have RHEL 5 installed on VMware 6.0 and the host OS is Windows 7. My Host is connected to internet using a wireless connection and works on shared IP. Earlier when I had Windows vista as host I have managed to get the internet connection on the RHEL but do not remember how I managed it. Now I need help in setting the internet connection on RHEL. I have set up a NAT connection. But of no use.

Anyway, according to the release notes, RHEL 6 has a PAE enabled kernel by default. Great... But that leaves me wondering why uname report SMP. Further, I'm provisioning some systems for QA use, and they're asking that PAE is disabled. My thinking is that since RHEL 6 requires PAE capability to install, there may be no way to disable it and the googling I've done seems to support this. tl;dr Why does a default kernel with PAE enabled report SMP on RHEL 6?

I have two problems. I installed a RHEL variant (scientific linux) on an already dual boot system with ubuntu and vista.
It replaced GRUB with (I think an older) GRUB version and to add to that I cannot see my ubuntu ditro anymore. is there a way of reinstalling the GRUB that came with ubuntu then adding the RHEL distro to it?
my second problem is that I cannot figure out how to enable wake on lan in scientific linux (RHEL). on ubuntu I would just write a small script and update all runlevels to run it at startup. what is the alternative on redhat?

After being fed up of all the problems I have had with Windows, I have just installed Mandrake Linux and everything seems OK apart from the fact that I can't connect to the internet. I presume it's because I have not got the relevant driver (or have not configured it if it's there) My machine was previously running Windows and all the disks I have are for Windows.
I have looked in my manual and it says I have a K8NBP GRAND (I think that's the motherboard, you'll see that I don't really know a lot!!) The manual also says Gigabit Ethernet LAN : NVIDIA Gigabit MAC + VITESSE Gigabit PHY - Supports 10/100/1000Base- T Ethernet/Fast Ethernet/Gigabit Ethernet. When I was running Windows I just had a network cable running out of the back of the PC connected to one of the LAN sockets on my router. I am currently having to use my wife's laptop (which runs on yet another OS but at least it connects to the internet or I'd be really stuffed).

I suddenly cannot connect to the internet from work and at home with my laptop. Both ethernet and wireless won't work. I still get an IP address, and can also ping it, but cannot ping other addresses. What befuddles me that it happened today at work and at home, that it worked fine at both places before, and that I just connected to the internet yesterday at an airport. I have not installed any new programs, nor have we changed our internet provider etc. My girlfriend's laptop (Windows -- gnnn) still can connect to the internet without problems.

a friend of mine recently wiped my computer (windows XP) and installed Linux. The internet provider is Comcast cable. I have not ever had a problem connecting w/ windows XP but now I can't connect to the internet.I've spent hours on the phone w/ IT at Comcast and they tell me that I have connection to their modem and I also have a valid IP number. They seem to think that it could be something as simple as a setting, somewhere in the program and advised me to contact Linux for a solution. I am anxious to use Linux as my friends rave about the performance and all the 'bells & whistles' so the speak.
I have since, reinstalled windows XP (because I need to use the internet a lot, but can't get connected to the internet with it either.Again Comcast shows that I have connection to their modem and I have a valid IP address, but still can not connect to the internet. They seem to think that since all other variables remain constant except for the installing of Linux that the problem lies somewhere in that install.

I have just finished installing Fedora 10 on my machine and I have it connected to the internet via ethernet cable. The problem is it wont connect at all for some reason.
I click on the green Activate button in network configuration to see if it does anything but I keep getting this AVC denial error. I don't even understand what the problem is:

So I play around in the settings and put this SELINUX thing to permissive but the thing still pops up, so it didn't help:

The only other thing I messed around with is the DNS server; I put two DNS servers in those boxes, and I got those from the people in charge so it shouldn't be wrong.

When using Fedora in VMWare, sometimes I can connect to the internet and sometimes I cannot. I do nothing differently on different days. I restart the machine and / or shut the machine down at the end of the day. When the machine starts back up the next time, I might have an internet connection or I might not have an internet connection. The 2 computer symbol that appears in the top will also sometimes be displayed. If I have that icon and click on it, it will display connections I can use including a sys one. I have a bridged connection chosen in VMWare also. Furthermore, when I click on the System -> Administration -> Network Device Control, 'eth0' is listed and it is listed as 'active'.
Yesterday I could ping out to a specific ip address on our network ( 192.168.1.xxx ). Now, I cannot ping that same ip address. I receive an error 'Destination host unreachable'.
How can I make it so that I have the internet connection every time I start up the machine? What do I need to check as far as the internet connection goes and the network connection?

I have an Internet connection problem. The computer I'm using which is running Red Hat Enterprize Linux Server cannot connect to Internet. I can ping machines working in our local network. Static IP addresses, DNS, Default Gateway, Subnet mask, they all seem to be correct. I restart network interfaces but that doesnt make any difference. Other machines in our local network are connecting to Internet without any problem.
