CentOS 5 Networking :: CentOS 5.2 And NVIDIA NForce Networking Controller
Jan 18, 2009
I'm having trouble to get connected to the internet on CentOS 5.2 . I have an NVIDIA nForce Networking Controller onboard. And I've been trying to find a driver for this, but I was unsuccesful so far. And if I have a driver, how do I install it? Could anyone please help me to get this working. I'm just a beginner with CentOS and Linux, so I don't have much experience yet. Oh, and I forget to say that Centos 5.2 on VMware does have internet, but I stopped using vmware because it became very laggy on my Vista OS, so I started to use dualboot.

I am unable to find Atheros AR8132 PCI-E Ethernet Controller driver for CentOS which is installed on my netbook.
I contacted DELL to provide me the driver and they said that they do not support Linux on netbook and I have to arrange it myself.
I told them that I don't need help in installing I just need the driver file to which they said that they don't have driver for Linux.
NIC is getting detected and works fine on the same netbook (Am dual booting Windows7/CentOS) with Windows7
When I type: ls -l /dev/ it does not show up eth0. Same result with ifconfig. When I type lspci | grep net it does show up something like Atheros Communications AR8132 L1 PCI Gigabit .

Filter access server through the net only to authenticated users from domain controller (Win2k). Server (Centos)(Firewall with 2 nic), which makes access to the net, with only 196MB RAM (PIII500Mhz), so I do not want a solution based on proxy or what resources it uses large I want a solution with a script that runs at login on windows this check series HDD and to communicate with Linux server that's open accessor another simple solutionNow just use only MAC filtering on

I can not get the node or cloud controllers to startup using the init.d scripts. I have a fresh install of CentOS 5.4 with Eucalyptus 1.6.2 I have compiled Eucalyptus and all packages using the RPM supplied from Eucalyptus and utilizing yum installer. I do not currently have any processes or applications listening currently on the ports on the boxes as well. I think it may be a permissions issue or something because I get a "permission denied error", but I am not sure if it is Eucalyptus or CentOS. It looks as if it is not binding to the address on the interface of the NIC. It may be something else however. I have the Node controller, Cloud controller, and Cluster controller on seperate physical boxes. When I try to run either the cloud controller or the node controller I get this message:
Cloud Controller:
[root@cluster-cont ~]# /etc/init.d/eucalyptus-cc start
Starting Eucalyptus cluster controller: (13)Permission denied: make_sock: could not bind to address [::]:8774
(13)Permission denied: make_sock: could not bind to address 0.0.0.0:8774

I have had a Supermicro X7DCL-3 motherboard based machine, running CentOS 5.2 x86_64, recently upgraded to 5.3.Strangely enough, although I must have installed the 5.2 using DVD disk, the running system does not show the DVD drive. The machine was not used very much so I noticed that only today, after the update. There is no trace of it in 'dmesg', thera are no /dev/cd* and/or /dev/dvd* devices. The IDE controller is IT8213 (as shown by 'lspci'). In 5.2 kernel (2.6.18-92.el5-x86_64) lspci says "unknown device". I have checked the /usr/src/kernels/*/.config files and both kernels (5.2 and 2.6.18-128.el5-x86_64 of 5.3) seam to have the support for that controller added into the kernel:CONFIG_BLK_DEV_IT821X=yAny idea why it is not working? The Supermicro has apparently noticed this also as their OS compatibility chart lists the IDE interface for that motherboard as supported up to RHEL 5.1 but not for 5.2.

I just started setting up a linux box in the office...I have some experience with ssh commands but not setting up a linux system and stuff.The box is connected to our network but I have no clue how to make windows & osx talk with it. How can I go by doing that and also setting up an apache server to be able to connect through network. Right now I have apache/linux/mysql running it works when i go to localhost, but I would also like to let all the computers in office to access it. I would guess that will deal with virtual host which I know how to setup. I just need to setup an IP.

I'm running a fresh install on an intel i7 system on an asus p6t deluxe v2 motherboard with the onboard NIC (Marvell Technology pci-e). I know the NIC is working as when I boot into the onboard OS that Asus provides (Asus Express Gate SSD)I have a working net connection.Booting up CentOS hangs at determining IP information for eth0 and eventually fails with the following error:PING xxx.170.30.1 from xxx.170.31.231 eth0: 56(84) bytes of data---xxx.170.30.1 ping statistics ---4 packets transmitted, o received, +3 errors, 100% packet loss, time 2999ms, pipe 3 failed.

I have a Centos 5.2 VM running under Windows 2008 Hyper-V. If I add two "legacy Nic's" and bridge them, everything appears to work fine. However, if I remove the legacy nics and replace them with two synthetic nics (linux integration components), the nics seems to function fine UNTIL I add them to a bridge.This VM will eventually be used as a DansGuardian/Squid transparent proxy for a local library. The logical layout is represented by the attached jpg image. I have also included the ifcfg- scripts for the adapters and bridge for both scenarios.It would also be useful if someone else has Hyper-V with the integration components and dual physical nics to see if they can reproduce my symptoms on their box.Legacy Adapters:
ifcfg-br0:
DEVICE=br0
BOOTPROTO=dhcp

This will be a little long (having read Phil's 'how to ask questions' FAQ). I'm trying to get OpenVPN working between my CentOS server and some Windoze laptops running XP. There seems to be plenty of sample
config files available, but to date, none of them have worked for me. Pulling out my trusty Wireshark, I've found some clues,
BACKGROUND:
My local subnet (NAT'ed by my gateway router) is 192.168.52.x. My router has been configured with a conduit (port-forward) for port 1194 (the standard OpenVPN port), which points towards my CentOS server.The CentOS server is .52.112, and the supplicant is .52.110. I have tried the lient both inside and outside my local subnet, with no difference in events or outcomes.

I've the Intel Corporation 82801CAM (ICH3) PRO/100 VE (LOM) Ethernet Controller also a wireless slot (I've the wireless card DWL-G650+) When I turn on the pc and I go to "Ethernet Device", I see set: peth0 (Intel Corporation 82801CAM (ICH3) PRO/100 VE (LOM) ETHERNET CONTROLLER) and also set "Bind to MAC address": fe:ff:ff:ff:ff:ff I've set manually the IP address (I'm under router). Status is "Active" but can't go on the Net. When I change to "eth0 (Intel EtherExpress/100 driver)...sometimes become "Active" an other times said that the MAC address is different or to check the cable because can't find the IP. What can I do?

I want to install CentOS from netinstall CD, but it doesn't work for wireless connection, because it just looks up for eth0 connection. Well, I connected server to wired USB connection and it's named eth1. I want to use netinstall CD but using eth1 connection. Is there any way for doing it?

Can anyone here point me to a walk-through or discussion of how to use Webmin to set up port forwarding/NAT on a dual-NIC Centos 5.3 box? The layout will be simple:
Internet --- NIC1 [CentOS Box] NIC2 --- Switch to other PCs
We have a BUNCH of exposed services that are on special ports -- for example, to connect to one machine, you go in with [IP_Address]:12000, and to connect to another, [IP_Address]:12002, etc., etc. We're currently using OpenSuse 10.3 on this box, and YaST makes this criminally easy (you give it the incoming port number and the destination IP/port numbers and it just works). But OpenSuse 10.3 is nearing EOL, we're buying a new machine, and I'd like to use CentOS on the new one.
I've read the sparse Webmin documentation in their Wiki, and it leads one to believe that you simply insert a "NAT" rule. But there's obviously something they're leaving out. I *am* opening the ports in the firewall. But when I log in to [IP_Address]:port, it just times out. The port forwarding never occurs. The test in this case is SSH, and I know that SSHD is working properly because I can log into that machine just fine from another PC on the same internal subnet.

I just upgraded from Ubuntu 9.04 64-bit, to CentOS 5.5 64-bit and my RT-73 USB network card doesn't seem to want to function. It always worked fine in Ubuntu by default (plug and play). Is there some setting I need to make to get this working?Even BT-3 (which is quite old) recognizes the RT-73.

I've tried to read many of the topics in this forum first and tried to find a solution to my problem, but can't find one.I'm testing CentOS 5.5, it's the first time I'm using a CentOS Linux release.I'm trying to configure the proxy "client side " on it and cannot find how to do it.On other Linux release I've used the ENV variable like "http_proxy" or "HTTP_PROXY" etc etc.This time, I don't know why but it doesn't work.I've put the name and @ip of the proxy in /etc/hosts and tried different version upper/lowercase of "http_proxy" "HTTP_proxy" "ftp_pr.." but it doesn't work.If I configure manually Firefox and puting the name or @ip of the proxy we have on our network, it works.But if I try to use ENV variable it doesn't work...

I am having a problem getting a wireless network connection on my DELL laptop running CentOS 5. I have no problem getting a wireless connection when the laptop is booted in Windows XP. I also don't have a problem when booted under CentOS 5 and there is no authentication setup on the wireless router. I only have a problem when I setup authentication. The router wireless log shows the PC connectinng, authenticating, and succeeding authentication.I am using the Broadcom Hybrid-wl wireless driver.

I am a developer, not a network admin - sorry if this ia dumb question. I need to test an application on CentOS 55 64 bit. The instalation went fine and initially I let DHCP work its magic. The router IP address ia 192.168.0.1 and all other VM's I have are granted dynamic ip address on this range (i.e. 192.168.0.x). However, the CentOS vm got an IP address that looks like it belongs on a different subnet :192.168.1.1
The VM (vmware desktop) network setting for this VM uses "Bridged: Connected directly to the physical network". I can ping the host (Windows 7 64 bit) and the host can ping it (it been the VM) - but no other computer on the network can see it. To make things easier, I changed the network configuration to use a static IP address. Here are my configuration files:
/etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=static
HWADDR=00:0C:29:83:4B:A4
ONBOOT=yes
TYPE=Ethernet

I have an MSI K9A2 Platinum mobo, which has a 10/100/1000 Fast Ethernet Realtek 8111B built-in, a D-Link DIR-655 Router and a DSL modem. Compared to Windows Visya and other Linux distros ( Fedora 11, Suse 11.1, Mandriva 2009.1 ) access to the internet is much slower. It seems there is a noticeable delay when running CentOS 5.3. before internet access kicks in each time I am surfing the web or updating my system.
Is there any way I can speed things up, or determine why CentOS 5.3 seems much slower ?
