Just looking for some general guidance with regard to installing over the native Windows 7 (x64) installation on my new Alienware M11x with RHEL 5. I have considered other Linux OS's such as Ubuntu Desktop, Fedora, and Open SuSe. However, I am of the opinion that RHEL will - from the jump - most fluidly integrate with the Intel Core i7 architecture, 1GB NVIDIA GeForce GT 335M, and other components. I plan to convert my existing Windows XP installation into a VMWare image and run that as a guest on my Alienware M11x (instead of alternatively running RHEL 5 as a guest). However, I am concerned whether it will be possible for the guest (Windows) OS (or any guest OS for that matter) to recognize/use the Alienware sound/video/LAN/Bluetooth EDR/WWAN/etc. (as the drivers were designed for Windows 7).

I have a situation where I want to install various versions of RHEL on removable drive. My first option was a flash drive or an external USB hard disk, but its speed is too slow.Now I have been assigned a task to search for more options about this requirement. If anybody has experience in installing the same, then please share with me.

I have a Dell Studio XPS 1640. The wireless card is a Broadcom Corporation Device 4353, and I'm using the Broadcom STA driver suggested in System>Administration>Hardware Drivers. Every couple of minutes, it disconnects from my network and then it spends several minutes reconnecting and gives me the "Authentication required by wireless network" prompt several times. The problem only exists in Lucid: it goes away when I use a Karmic live CD, and a similar XPS computer with perfect wireless performance in Karmic has the same problem when I run Lucid on that one. Aside from downgrading to Karmic, how can I fix this?

Two years ago, I have set up two node Active-passive cluster on VSphere 4.0 and it is in production ever since.
I've tried to setup another cluster for testing purposes on the same VSphere, and failed. And what is interesting is that those new two nodes came up with cluster.conf of the production cluster, even though I did not try to bring them in the existing production cluster. I googled a bit and found something stating that two different clusters might behave strane if on the same network segment. Question is, did anyone try to create two different clusters on the same hardware, or on the same network VLAN?
I will do some more digging after weekend, and get back to you.

I have a RHEL 5 Server dedicated to web hosting. HTTPD 2.2.x.x is running on it with PHP and MySQL. The machine is not a server system (hardware wise, a C2D 2.66 with 2GB RAM and 2 x NICs). I have a CIR Fiber link with a pool of live IPs. The machines including this web server is plugged into a switch which has all the live interfaces and is separate from the LAN switches. The problem i am facing is that, when ever this web server is plugged in, the traffic on live switch is choked. Internet slows down to a halt (as live interface of proxy is plugged in this switch. DNS stops resolving name due to time outs. Mail delivery is slowed and the mail ques pile ups. The moment i get this machine of the switch, all the traffic becomes normal. Therefore i have deduced that this is the faulty server. I do not know if this server is hacked and working as a bot or it is a mere hardware problem(faulty LAN Card).

My Dell Vostro 1520's Dell Wireless 1397 WLAN Mini-Card must not have been set-up correctly, as the Network Manager won't even let me select the wireless tab. Please just explain to me, step by step, what exactly I must do to make it work! Additionally, I can't figure out how to disable my Touchpad's Tap to Click funtionality, which must be done if I'm to effectively use my current KDE installation of openSUSE

I have a rack of Dell 1750s running RHEL 5.3 and we just upgraded the memory from 4GB to 8GB. When the machine boots, the BIOS probes out 8GB, but the boot scroll (dmesg) only shows 4GB, as seen after we login. How can I get it to see all of the mem?

I have a Dell Precison 690 system in my lab. I want to downgrade the system from RHEL 5 to RHEL $ since some of my software is not working in RHEL 5. I have the installation CD and the dell driver CD. There are 2 cd drives in the system and I am using both the CDS at the same time. But when the installation asks to select hda or hdb to get the driver cd. I put the CD in the second cd dirve which is connected to hdb. When I select hdb it is not recognizing the cd. When I skip the driver selection step I am getting the error:"No valid device were found on which to create new file"I have used the following and nothing worked:
linux noprobe
linux apci blah blah off
linux all generic blah blah blah

I think the gx620 is called "64-bit capable" or something like that. I get the idea it's not a true 64-bit machine. I am thinking about getting CentOS 6.x (when it comes out) to learn rhel 6.x. Some features, like KVM, only work on 64-bit. I am seeing gx620s on craigslist for about $100.

I'm having issues with my wired network. After about 5-10 minutes of turning on my machine, the network will drop out. Sometimes rebooting my pc or router will fix the connection, other times it will have no effect. Also, sometimes the connection will completely disconnect, other times it will appear to be connected (i.e. the network icon will indicate that there is a connection), but trying to ping a remote server or the router will fail.
This problem first showed up on Fedora 11 64, however I've just installed Fedora 13 64 and that hasn't helped. I'm using a brand new NIC (I've tried using the onboard NICs). The machine also has Windows 7 installed, which is able to connect just fine. Apart from changing NICs, the only other thing I've tried is switching from dhcp to a static IP address.

I have a Dell 1435 with an AMD Opteron 64 bit chip, however when I install RHEL 5.5 I only get a 32 bit OS. The disk I'm using to install RH is the 64 bit copy, it says "For 64-bit AMD64 and INTEL 64" on the front of the disk. After the install I do a "uname -m" and it displays "i686" which indicates a 32 bit OS.1. Why does this happen?2. Is there a CL option that will allow me to force an install of the 64 bit os?I'm confused.I've installed literally over 100 systems and this never happened.

So basically what I am trying to do is install Ubuntu 10.04 on a Dell Poweredge 2600 server. Right now I dont care wither I get the server version or the desktop version, I just need to get it on their. this is what I have run into. When installing the regular Ubuntu 10.04 desktop for 32bit, the server just locks up on the very first ubuntu install screen and the keyboard lights just start blinking non stop. When I use the server version, the server get to the Detecting Network Hardware and locks up at 94% and the keyboard will also start blinking nonstop. I have looked all over for an answer to this problem and have yet to find one. This guy figured out how to make it work but he never mentioned what version he was using. [URL]..
On this server I have 6 HDs, 5 of them are RAID 0 with 1 Hot Spare. I have also tried using the ubuntu-10.04.1-alternate-i386.iso.torrent and still had the same problem. I have spent the last 3 days searching all over google and the forum to an answer but had no luck.

is possible to edited the default RHEL CD to have it automatically install RHEL based off of a kickstart file that I will store locally on the CD. My plan would be to put a cd in a server and have the OS automatically being installed.

I received an amber light warning "IB110 - SBE Log Disabled." I've learned from Red Hat documentation that this is "for information only". Where can I find a better explanation of this warning? Also, what is the SBE Log, how can I enable it, and where can I view it? It doesn't seem to be in /var

I have a database server running RHEL 5.1 32 bit that suffered some catastrophic failures about 6 months ago. We were able to patch it back together and keep it running, but now the manufacturing site it supports is going to shut down for two weeks and I would like to replace it permenantly. Does anyone have any guidance for that sort of thing? I'd like to have the new server up and running before hand, basically changing the hostname/ip and restoring the databases only on conversion day. I've done this in the past with HP UX - Red Hat conversions, but this is my first red hat to red hat move. Any advice or shortcuts?I forgot to add the other wrinkle. The new server will be running 64bit linux.

i want to make sure my mail server is behaving as expected. the past two nights, i've received logwatch notices below. the section in question is the 20 or so deferrals from some .ru e-mail address. i've since removed the user that registered on my wordpress blog (wlvp@yandex.ru) and added the three IP address to iptables DROP, but these "e-mails" still look like they're in some queue unless i'm reading wrong. i've removed known usernames in case you find the numbers useful. why are all these deferred messages here? if they're stuck in a queue, can i remove them?

I am far too often getting connections dropped when trying to load web pages from my local server. From my mac running Safari I get the error message "Safari can't open the page...because the server unexpectedly dropped the connection." From Firefox on my Ubuntu 0.10 desktop it opens the window that says "You have chosen to open index.php..." and ask if I should edit the file or save it. When I tail the apache2 access.log it shows the previous successful page load but the one that failed is not mentioned. In error.log I get some stuff I don't understand, except the last line which says aborted:
b7819000-b781b000 rw-p 00000000 00:00 0

I want to know something: i have a OS based on Debian configured and installed on a machine that controls all the network. Then, I can access it via another machine (with Windows for example) (connected by crossover cable or using a switch) by a web browser where I can do everything, including adding hosts, adding users, configure mail servers, voip, configure domains, etc etc etc..I would like to install Nagios on my server but I would like to monitor the hosts, routers that I have on the network using the Windows machine. How can I do that? Isn't it supposed to access the nagios information only in the machine where it is installed?

I'm the DBA for a number of Oracle RAC databases running on RHEL 4 and our SA has moved on, leaving me with some tasks to do before we get the next SA. One task is to get a list of all applications installed on our linux servers. I know I can get a list of all rpms via "rpm -qa | less" but that spits out every rpm, which is not what I want.How can I get a list of all applications installed? For example "oracle database version 10.2.0.4", yada yada.

have installed RHEL 5 recently and want to use internet on it. However it doesn't activate my connection when I try activating it through System>Administration>Network>Devices Tab.
My network adapter is "Realtek RTL8139/810x Family Fast Ethernet NIC", and processor is Intel Core 2 Duo. I read in a thread somewhere to edit a file named resolv.conf to include DNS server address, but don't know how to go about it exactly. I asked my ISP and he gave me two DNS Ip addresses
