Hi, I have a problematic CentOS XEN server and hope someone could point me in the right direction to optimize it a bit. The server runs on a Core2Quad 9300, with 8GB RAM (max motherboard can take, 1U chassis) on an Intel motherboard with a 1TB SATA HDD. dom0 is set to 512MB limit with a few small XEM VM''s running: root@zaxen01:[~]$ xm list Name ID

Has anyone succesfully setup, and used CentOS as an iSCSI server? I'm trying to setup a server with 4x500GB HDD's, setup in RAID 10 to act as an iSCSI server for a virtualization project, but I can't find a decent howto on how to setup an iSCSI server using CentOS. I would like to setup something like Openfiler, but we also need todo some other stuff that OpenFiler doesn't

Hi all, Can anyone please tell me, from experience, if it's possible to upgrade the hard drives in a RAID 10 system from 250GB HDD's to 500GB / 750GB HDD's, while the server is running? The server runs CentOS 5.5 x64. Our hardware vendors simply always say no, so we never actually tried doing this, and when a client needed an upgrade like this we had to build a new server with the

Hi all I want to look at setting up a simple / cheap SAN / NAS server using normal PIV motherboard, 2GB (or even more) RAM, Core 2 Duo CPU (probably a Intel 6700 / 6750 / 6800) & some SATA HDD's (4 or 6x 320GB - 750GB). My budget is limited, so I can't afford a pre-built NAS device. Can this be done with CentOS? I've been looking FreeNAS (which is built on FreeBSD), and it

Hi all I'm looking at setting up software RAID 10, using CentOS 5.1 x64 - what is the best way todo this? I'm reading some sources on the internet, and get a lot of different "suggestions" 1 suggestion says to boot up with a Live CD like Knoppix or SystemRescueCD, setup the RAID 10 partitions, and then install Linux from there. 2. Another is to setup a small RAID 1 on the

Hi all If I do a "dig mydomain.co.za" from a Linux server, how do I know which DNS nameserver returns the queries? I seem to have a faulty DNS server, but can't see which one, so I want to find out which nameserver (if there's 4 - ns1.myserver, ns2.myserver, ns3.myserver & ns4.myserver) returns the queries? -- Kind Regards Rudi Ahlers CEO, SoftDux Web:

Hi all, I need to setup a real bare minimum CentOS Virtual Machine, but with normal internet / network access. i.e. I need SSH, Mutt, Links, lynx, ping, tracert, dig, iptables, etc. Does anyone know where (if?) I can get a list of applications which gets installed with CentOS 6 if every option is deselected in the installer so that I can see what I can remove which isn't really necessary

HVM = fully virtualized. The question is, why are you using fully virtualized domUs?

Hi, Does anyone know of a stable / working "2way authentication" system for SSH, and even web authentication services? Most of the banks in South Africa have a system that, when you want to make a payment, they send you an SMS and you need to verify the action with a secret code which was SMS'd to you. gmail also has this. Does anyone know of a "universal" plugin /

Hi all, Has anyone seen something like this before: I want to use a laptop as a KVM console. Basically when a technician goes to one of our datacentres, or clients he has to look for a free LCD, keyboard & mouse to connect to a server (no network access, reinstall, troubleshoot failed kernel / HDD, etc). And then hopefully there's an open power socker in that cabinet. So I'm

Hi all, Has anyone managed to get CentOS 6 domU (i.e. guest) working on a Debian 6 do0? Both OS''s are 32bit and I''m running XEN 4.0.1 with HVM support.

Hi all I've been thinking about using CentOS on a Dell R200 server and turn it into a firewall / network monitor / traffic shaper in our datacentre, instead of using a dedicated firewall device. One of the devices that I have been looking at, with my limited budget, is the D-Link DFL 860 - http://www.netdefend.eu/Product.aspx?m=15&ref=DFL-860 It provides AV, SPI, VPN, DOS, P2P, etc

Hi all, Does anyone know how to control a hard drive light from Linux? I'm building a 24bay Linux File server which will run software RAID and I need an easy way for the engineers to see which HDD has gone bad. Most of our NAS devices has 2 lights on the hard drive cages and they automatically signal a bad one (reg light, light constant on , etc) but I can't figure out how todo this from

Sorry about the previous post, I see the subject had a typo. So here's the correct one :) Does anyone know how to configure Postfix to use SMTP authentication on a relay host? i.e. I have a Linux server, running PostFix on an ADSL line with a dynamic IP. Thus I can't just send out emails from this server but need to relay it via our ISP's SMTP server, which is very unreliable. Now

Hi all This may sound funny, but I can't get onto any websites right now, so I can't even google.

I know it's got something todo with mkisofs, but I'm not 100% sure what the commands should look like Can someone please give me a sample of the whole
