CentOS 5 Networking :: Getting Recommendations For Replace Server NIC In Dell R610?
Dec 23, 2009
We have 6 Dell r610 running CentOS 5.4 with stock kernels, with a couple of Broadcom NetExtreme II 5706c 1GB NICs in them. The NICs are flaking under load, and we'd like to try some alternative NICs (in additional to playing around with driver and firmware upgrades to see if the Netextreme II's can be made stable). Assuming we do not want to do bonding or TOE and just want basic solid transport, can anyone recommend a server NIC that is rock solid with CentOS 5.4? The goal is stable as source-able, we just want to get some baseline functionality up and running while we fight the broadcom issues.

I am having a problem recognizing the full 24GB memory on a dell PowerEdge R610 system I just purchased. This is the Fedora 11 preview version, uname -a returns this:Linux comp1 2.6.29.3-140.fc11.x86_64 #1 SMP Tue May 12 10:44:27 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux
this is the off the shelf box from Dell and it is a quad-core with 24GB memory, but the OS can only recognize about 3GB, here is the free -m
total used free shared buffers cached
Mem: 2980 607 2373 0 24 176
the system is otherwise functioning normal. how to get the full 24GB of mem recognized?

I am running a server in Dell which has RAID1 and hot plug 2 disks. It's been running for a while, but I was thinking it may crash anytime. So got a spare one, and wanted to test it how it works.I have never done this before. Can I simply, on a running machine, unplug the Disk 2 and connect the new Disk there? (Without interrupting the service as a silent mode?) Or does it have to be shutdown first, and unplugged, reinstalling all software/centos/etc etc? How do you do this update? Also how do you know when you replaced the disk? Do you have anything special to monitor that disk 1 or disk 2 is end of life?

I just installed 5.4 on a home machine and I would like to get a UPS that will auto shutdown the server if the power goes out. Here an inexpensive tripplite from Costco. [URL] I only need it to shut down the 1 centos 5.4 machine if the power fails. Tripplite has linux software now that will shutdown machines. [URL]

I'm setting up an email server for a small office and need a few specific features. I was hoping that someone might give me a few recommendations to meet the following criteria:
IMAP support anti-spam some sort of webmail client - doesn't have to be fancy, but it needs a search function graphical administration panel The last one is so that other people in the office, who aren't necessarily familiar with linux, can do some basic administration. Adding mail boxes, etc.
I've seen the guide for Postfix/Dovecot. That's great but doesn't cover everything that I need. I've also seen Zimbra, which... Well I don't know, that may work, but the open source version has some features removed and that makes me leery. Have people had good experiences with open-source Zimbra? Is it sufficiently feature-complete?
Edit: Well, looks like I just needed to do a little more searching. This seems to cover most everything:[URL]... I'd still like to hear what people have to say about Zimbra though.

I'm looking for a rock solid stable USB wireless driver supported in CentOS 5.2 or even 5.3 (when it's released). I'd like specific manufacturer and model recommendations if possible. I want to stay away from zd1211rw and ndiswrapper.
I've tried a zd1211rw based SMC device with miserable results. I backported the USB IDs from 2.6.25 to get it working, as well as tried the RHEL 5.3 backported module. With both, zd1211rw intermittently creates a soft lockup situation where all ptys and ttys freeze. Pings, and other non-{p,t}ty services still work okay, but I have to halt via the power switch then reboot to get things back to normal.

I have a dell XPS m1530 which I think has an Intel wireless card (iw3945 i think). It's been giving me intermittent troubles since I bought it a few years ago, but never that bad.Recently it's been getting worse, and since ubuntu doesn't have the in-depth tools that windows vista did for resetting the wireless adaptor, it's been more trouble since switching.
I'm thinking of replacing the card altogether. I'd like to know if it's possible to remove and replace it for my laptop, and what kind of card would fit and work well with ubuntu.What would you guys recommend?PS- looking around the net it seems like this card has a lot of issues, is this just a badly made wireless card?

We have 9 windows stations on XP and also Xp on the server to do file sharing. Now the boss wants a domain environment and has asked me to look at Fedora So what we want is filesharing, like word .xls ,pdf docs etc Also we want to restrict what the user workstations can do.We want to their profiles on the server, so when they login in all profile information like the desktop, my documents loads.If one PC for some reason gives in ,they can login on another and continue working.

I have a Dell PowerEdge 1950 with Centos 5.4 installed. I am having an issue where there is no network activity on any of the NIC's.(Broadcom and Intel).
I have read that this might be somewhat common but have not found any solutions. I am unable to ping anything internal or external. Has anyone encountered this problem and have a potential fix?

I have agreed to set up a server to run an existing website from a hosted solution. This is no problem I have setup Centos 5.5 64 bit, all running OK. The existing site is single directory HTML with a very small amount of Java script.The user has no technical knowledge and would like to be able to go in and modify their site, sadly vim is not an option
Has anyone got any suggestion of single or multi site CMS solutions that are easy to set up and use. I would also need to import the existing site. I do not have weeks to spend learning a new product at the moment though I would love to do so.

I have installed CentOS 5 just downloaded yesterday on a Dell D620. Everything but the wireless card works. So I found this article:
http://wiki.centos.org/HowTos/Laptops/Wireless/Broadcom
and followed it step by step and was able to complete all of the tasks. The problem is that obviously it still won't start. It is not even recognized as an adapter but when I run lspci -v it is there sure enough. When I look under the networking GUI it is listed there but it has no MAC assigned to it. Please let me know what command output you need to see and I'll get here asap. I have searched this forum and other sites and nothing so far has worked.

This week I picked up a Dell Studio Hybrid and installed CentOS on it. I originally used 5.0 since I already had the DVD and the network card wasn't recognized at all (lspci recognized it but the card didn't show up in system-config-network). I then downloaded the 5.2 DVD and installed that. The network card then showed up in system-config-network but it still didn't work. If DHCP is enabled it tells me that no link is present, and if I manually configure it, I still can't ping the router. lspci reports the following about the network card:
02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 02)
The driver used is r8169.
I put Fedora 10 on it and the network is working fine, but I'd rather run CentOS on this machine. Is the issue likely to be fixed with CentOS 5.3 or should I just stick with Fedora?

I'm looking for an application that can run remotely to periodically check a webserver to ensure that it's delivering pages. I can't use one of the free web-based services because the servers I'm monitoring are closed to the outside internet. I have internal client machines I'd like to install the monitoring tool onto that can check specific URLs in both HTTP and HTTPS. Then email a notification when something stops responding. It would be nice to have a tool that is platform agnostic (written in perl, python, etc.) so I could have flexibility in what type of client machine I use for the monitoring.

I presently have an Ubuntu server 64-bit running VMware Server 2.0 in a test lab. The server was created using the default partitioning method during the installation. So I have what I think is just one huge 300GB partition along with what I hear is a uselessly large swap partition.
I keep reading that theres an advantage to creating dedicated partitions, especially for the the VM datastore.
If the advantages are true then I would like to re-partition the drive.
What partitions should I define and how big should the be?

I have found it difficult to research a wireless print server which will be supported on Linux. I use Debian 6 and Ubuntu 10.04 (also Windows 7 64 bit, Vista, and MACOS Snow Leopard). Everyone in my household using uses a different OS, so it is all the more difficult to ensure interoperability across so many OSs. Where can I find a definitive, authoritative and complete list of supported print servers? Also, I want to keep things simple as possible. This is an important criterion for my choice of wireless print server.
GUI mediated setup/install is much preferred over complex configuration files and command line. I know of CUPs, but I don't know if CUPs will regulate the wireless print server and what's involved. The print server is to enable sharing of Brother HL-4050CDN printer. I'm seriously considering F5L049au (see Belkin : Home Base). But the customer support people tell me it does not support Linux. But this is true of the majority of the print server market. Must support N network standard, the printer above, be wireless, and be Linux compatible.

I'm building my first server to use as a Counter Strike: Source game server that I'm hoping will host 24-48 players. I plan on using Ubuntu Server 10.04 64bit. I also plan on using it as my own personal file server. I'm looking at building it with the Intel Xeon E3110 3.0GHz, 1333MHz, Wolfdale, dual-core processor (LGA 775) as it's cheap and from what I've read, should fit my needs.
Initially I want to build the server with a single SSD drive just to get the system up and running and then later I wanna add another SSD to mirror the original with RAID 1. Then I want to add 4 large capacity SATA drives in a RAID 10 for storage (after I've gotten everything else set up).
Can anyone recommend a motherboard that will fit this setup? I'd really like a motherboard that has built in VGA graphics so I don't have to buy a graphics card just for the install (as I plan on using SSH after I get it up and running). I don't plan on using ECC memory as I need the memory to be fast (for the game server). Because this is my first build, I'm very new to installing/setting up RAID. Do any motherboards exist that have a built-in hardware RAID that will work with Ubuntu and let me do raid 1 and raid 10? Or will I have to get a SATA RAID card? Will hardware based RAID allow me to build a raid 1 array with a SSD drive that's already in use (my system drive) without having to reformat/re-partition?

I have a small Dell PowerEdge 1650 server with Fedora 12 loaded. We can access the internet, (Google, our home page, Etc.) but can not ping any local or outside IP addressed. Our internal computers can ping each other but not the server. No, it is not the server firewall because we also disabled it and still the same results.

I'm building a new file/media server for my household to use, and would like to hear the experiences of others, and suggestions, or links to appropriate howto's. I'll be using two (2) 250 GB Western Digital RE4 drives mirrored via mdadm RAID 1 for the Operating System. The storage area will be handled by four (4) 500 GB Western Digital RE4 drives in a RAID 5 array, managed by an Areca 1210 controller.
What I'd like to configure is a basic Samba file server, on which we have individual user folders, and a shared drive. As well, I'd like to add the ability to manage our movie collection so it can be accessed by the Boxee Box attached to the television. Twonky looks promising (and I don't mind paying the $19.95 for something that works well). However, as this is new to me, there may be other solutions out there that are better, and easier to administer. Moving forward, I'd like to explore the feasibility of configuring LDAP on this machine to authenticate users on the network (perhaps even integrate the mail server somehow), and the remote users (only two) who VPN into the network using the pfSense firewall appliance. There are no Windows servers, so Active Directory is not a factor.

I am looking for recommendations for a broadband card for use in North Central Illinois.I want to go the prepaid route as I will not need the card on a regular basis. I found T-Mobile, Verizon, Virgin Mobile, and Cricket. Cricket is not an option as they do not serve the area I will be in. So can anyone recommend a carrier and a broadband card that is Linux friendly and works well?

I'm looking at various low power consumption system options for running CentOS 5 on. The goal is to get a system that draws 20 watts or less, is silent (but I'll settle for very quiet), and is fast enough to be a light duty server. The kinds of things I envisage for it are low volume mail, http, ftp, subversion, ssh, maybe samba, and perhaps asterisk if I get enthused enough. Wireless network support isn't something I'll need and realistically the system is going to spend most of its running life being idle. I don't foresee any particular need to run X on it as I imagine that if I ever need to configure something graphically I'll do so by forwarding X over ssh.
I'm leaning towards the Asus Eee Box B202 as it's readily available, seems to be in the ball park of what I want, and I see on the forums here that other people have had success running CentOS 5 on it. Still, I'd prefer a silent system (though I suspect silent systems may only be available at a premium). So I'm after war stories and recommendations. What other low power systems have you run? For the Eee Box B202 or other system what kinds of real world power usage figures have you seen with CentOS when idle and when under load? Did the system perform below your expectations? If you needed to change the hardware (say, replace or upgrade the hard drive), was that straightforward or was it a chore?
