Red Hat :: CentOS 5.4 PS/2 Keyboard Didn't Work

Jan 22, 2010

Just installed CentOS 5.4, had no problems until the first time it tried to login, where the keyboard didn't work. There are bugs logged on both the CentOS site, and the Red Hat site, but nobody seems to have a definitive solution (other than buy a USB keyboard). Bearing in mind that the machine in question is not hooked up to a network (i.e. no internet updates), is there a way to resolve this issue?

CentOS 5 :: Can't Get Cluster To Work (aisexec Daemon Didn't Start)

Oct 14, 2009

I have problems setting up a (2 server) cluster. I get the following messages in syslog:

Oct 14 13:02:21 korzel ccsd[7823]: Starting ccsd 2.0.115:
Oct 14 13:02:21 korzel ccsd[7823]: Built: Sep 3 2009 23:26:21

Oct 14 13:02:21 korzel ccsd[7823]: cluster.conf (cluster name = cl_vpanel, version = 1) found.


Tried with the "basic" hosts file as well, eg with only the localhost lines in it. Both server run centos 5.3, up-to-date.There is no real error anywhere which might explain WHY aisexec daemon won't start. When i start openais manually (/etc/init.d/openais start) it starts without any errors.

CentOS 5 Networking :: Wireless Intersil Prism 2 Driver Installation Didn't Work?

Dec 20, 2010

I am a linux newbie, I spent more than 3 days trying to set up the drivers for my Intersil Prism 2 Wi-Fi adapter on CentOS 5.5. While trying to Make the driver source I receive errors of missing libraries. Is the hostap driver included in the Centos Kernel? I tried with insmod hostap but it didn't work..? Is there a kernel patch with the hostap drivers? I will be glad if someone can give me ideas or directions for setting up the driver properly.

Networking :: IP Forwarding Not Working On Centos Server

Jan 18, 2010

I am setting up a new server with 2 nics installed. Nic0 goes to the firewall and nic1 goes to the internal engineering network.

Problem is Ip forwarding is not working!

Server Name - slick
Firewall Name - gateone
engineering node - crooked

Routing on slick:

From crooked ( which is inside the server (slick) with an ip address of xx.xx.221.249 the only way I can ping or anything outside of the firewall ( gateone) is to turn on IPtables with this configuration:

I don't want to use IPtables. I need the ip forwarding to work.

Fedora :: X Crashes - Ssh To A Remote Centos Server Using X11 Forwarding

Nov 24, 2009

My X crashes when I...

1) ssh to a remote centos server using X11 forwarding
2) open the virt-manager remote application (the virtualization management app)
3) Open the remote console

Just to be clear, my local X11 crashes. I get back to the log in screen.

I get in my Xorg log:


Fatal server error:

-Is this enough for a bug report?
-How I can make X dump a core file for better debugging?
-Do -debug RPM packages still exist, and if so, should I install one for the X server and will this help with debugging, and if so, how do I install it.

Server :: OpenVPN Range Address / When Change Static IP To Dynamic IP In Config File OpenVPN Didn't Work?

Feb 13, 2010

I want to configure a VPN over the Internet.I installed the 'openvpn' package, generated the key file, transfered it by a secure way to the client, and setted up the configuration file.

So, in that configuration file I input the IP addresses of the tunneled interfaces. Both IPs are static in the tunnel.

Then, I've heard somewhere that I can assign a dynamic configuration IP for the client. I do this registering a range.

Well, when I tried to change static IP to dynamic IP (changing '' to '') in the configuration file, the OpenVPN didn't work.

Obviously I don't know what I'm doing, and I really, don't believe that simply changing the IP will make it work, but I tried.

I hope I explained my problem as well.

My configuration file:

# OpenVPN Server Configuration File
dev tun 0
cd /etc/openvpn
secret key_file

In client I execute the 'openvpn' without the '--daemon' parameter.Then I want that my client uses a IP in a range (, for example), instead of a static IP ( also thought to use a DHCP server, but I'm not sure that will work.

CentOS 5 Networking :: Use Webmin To Set Up Port Forwarding/NAT On A Dual-NIC Centos 5.3 Box?

Aug 31, 2009

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.

Ubuntu :: Graphics Card Didn't Work

Feb 11, 2011

My laptop is an HP Pavilion dv6 3078-tx. It is was a great laptop when it was running windows 7 but when I tried installing Ubuntu, I slowly began to hate it more and more. The issue is with the ATI and Intel switchable graphics card. Ubuntu installs fine and things seem to be great but I cant use the better graphics effects in ubuntu. I installed the driver that ubuntu provides for ATI and it didnt work and ubuntu booted into a terminal etc.. and I had to put it back to the way it was before. After sometime researching on the internet I know the problem is with the swtichable graphics.

Unfortunatley there is no option to turn off switchable graphic in my bios and hp arent much of a help. I dont know what to do now ? Is there any way to get switchable graphics to w ork with linux, is there way to get version of the bios that lets me disable it ? any variations of ubuntu or linux that it works with. I would prefer to use the ATI if i have to disable one or the other cause Im usually running on ac power anyways.

The error is basically that it doesn't seem to recognize it anymore.. it doesn't recognise any network hardware other that the built in ethernet card (which for some reason got the name eth2, suggesting that there is an eth0 and eth1 but ifconfig doesn't show them)

Debian :: Didn't Work With The Default Wireless Drivers

Jul 20, 2010

I have gotten Debian working quite well on my Sony Vaio laptop for the past 6 months or so, and it's a very rewarding experience. I however have a small amount of problems that I could not find the answer to through googling or reading Debian instructions.

1) I have an Atheros-based wireless chipset in my laptop that didn't work with the default wireless drivers in Debian. So I replaced them with madwifi drivers and it works great now. However, every time I restart the computer, it defaults back to 1mb/s wireless speed; making me go into root terminal and change the speed with "iwconfig ath0 rate 54M". Obviously this gets a little bit annoying to enter every time, so I am looking for a way to make it automatic. I have looked on Google and gotten some hits but none of them have been successful.

2) Whenever I put the computer on stand-by then return, the wifi refuses to connect. Networkmanager tries to connect then crashes. I have found no hits on this issue with my configuration. Very odd.

Fedora Networking :: ZTE MF627 3G USB Dongle On 3UK Didn't Work

I bought the modem above (ZTE MF627), which works great in Windows 7. My laptop dual boots between Windows 7 and Fedora 12, so I rebooted into Fedora and spent a few hours trying to get the modem working. Scouring the Ubuntu forums (as there's only one post on these forums and it simply didn't work), I found a few possible solutions, but nothing seems to be solving the problem. Here goes... The modem gets picked up by the kernel and appears as a USB device.

OpenSUSE Hardware :: Brightness Controls Didn't Work ?

Jul 21, 2011

Recently I tried putting Kubuntu Natty Narwhal on yet again and to my surprise it mostly worked. The only major thing wrong with it was my brightness controls didn't work (I have a VPCCW21FX laptop) at first this was an anoyance being blinded by my screen but I soon realized that it was killing my battery life. So having tried to seek help in getting it to work I tried out OpenSUSE. They worked! but as soon as I updated the kernal they no longer worked. No Problem. I reinstalled and told it to never apply that update. Then I installed the official nvidia drivers via repository on the opensuse wiki. they installed and worked but my brightness controls were once again broken.

Sony VPCCW21FX Laptop. Intel Core I3 Nvidia 310M

Nvidia Driver version 270.41.06-5.1 x86_64

Ubuntu Multimedia :: ATI Catalyst Didn't Work After The Upgrade To 10

Jun 12, 2010

Maybe saying Ubuntu is getting worse is unfair. I'm not a big user I have to say. I use it more out of curiosity than anything else. I first used 8 and it was brilliant. I told all my mates about it. Everything work great. I had all desktop effects. I could use a KDE session. Then I upgraded to 9 and lost KDE ability but still had all desktop effects available. Upgraded to 10 a few weeks ago and now no desktop effects. Non of the above is a problem but I feel like, for me, it's going backwards.

I use an old AMD 2600 machine with a Radeon 9600. I used to be able to use ATI Catalyst but that didn't work after the upgrade to 10 and I can't seem to find a solution. Ubuntu is still brilliant but I don't like things being taken away from me.

Ubuntu Installation :: Upgrading To 2.6.35 Kernel Which Didn't Work Either?

Aug 26, 2010

Wow -everything works with alpha-3 version with a fresh install. Sound, wireless modem, processor speed scaling, sound controls, touch pad, all cores running,power management, battery, fans, etc. NVidia driver is also working. I tried multiple other distro installs - opensuse, Fedora, and ubuntu 10.04 - none worked. Also tried upgrading from 10.04 to 10.10 which didn't work either. also tried upgrading to 2.6.35 kernel which didn't work either.

I'm running a toshiba satellite a505-6030 with an i7 core, nvidia graphics gforce 310M. i didn't have to pass any arguments to grub either . First boot seemed to stall, rebooted machine, and it's been working perfectly since.
