Which Operating System
There's bloody heaps of them. Which one do I go for on my two new file servers? Which operating system out of these is the most common, has the most support, is most compatible? The server will be used to host videos and will run c-panel. A light weight OS is probably preferred but I really have no idea. And incase it helps, the servers have 512mb of ram, about 30 - 40GB of hDD (not actually sure) and an old AMD Duron. CentOS Debian Direct Admin Fedora FreeBSD Gentoo LiveCD Redhat Slackware

Determining Operating System (Linux)
Without having all of the operating systems at my disposal for testing, I would like to figure out a way to determine the operating system of a remotely accessed Linux machine. It seems pretty strange though, since cPanel reports both machines I am using as being CENTOS Enterprise 4.5 i686, yet one's uname -a reports: Code: Linux hostsentry.crucialwebhost.com 2.6.9-023stab044.4-enterprise #1 SMP Thu May 24 17:41:23 MSD 2007 i686 i686 i386 GNU/Linux Code: Linux main.7kb.org 2.6.9-55.0.6.ELsmp #1 SMP Tue Sep 4 21:36:00 EDT 2007 i686 i686 i386 GNU/Linux I'm assuming there is a way to determine the OS from this information. Anyone know how?

Preferred Operating System For Web Serving
I have been online since 95 and I've got a lot of information I could help others with regarding web development and interface design. One thing I'm terrible at is System Administration, but I'm getting better and my first step is to pick a reliable operating system for both the webservers and the database servers. Would anyone be willing to answer the following questions or point me to a thread that already discusses these? A little background, our site has 200k members, 30k active and is growing by about 5k a week. We still run MySQL 4.0.27 on the DB servers and they are running FC2. The webservers are Apache 1.3.37 and PHP 4.4.2 running FC2 and FC4 as well. My questions 1. What OS would you prefer to upgrade to for the web servers? and a "few" reasons why? 2. What OS would you prefer to upgrade to for the database servers? and a "few" reasons why?

KVM Hypervisor And Guest OS Setup
I have been using Linux for the past 3 or so years, either running it for workstations or servers, and now I want to set up a server for Virtualization. I have been doing a fair bit of research about the different ways of doing this, and I have decided to go with KVM. I usually use CentOS, but will have to use Debian to use KVM. I just have a few questions about the best way of setting it up. We have a pretty powerful server* which we are planning on collocating to a data centre and running web servers from the VMs. Virtualization seems like the best way to allow for simpler administration, and also allow us get the most out of our server's resources. *Intel Xeon X3230 Quad Core, 8GB Ram, 4x 15k 147gb SAS (RAID 6) What is the best way to set this up then? I was thinking we could install Debian as the Host/Hypervisor over the whole drive, and give it a 16GB swap partition. Then I guess when the VMs are installed they live on the Debian drive as a file, or do they need their own partitions? Are the guest OS's capable of using the Host's swap space? Its bad enough losing 16GB as a swap partition to the host OS, but please don't tell me I need to supply the VMs with their own swap partition aswell - im curious as to if the server will ever need to use swap space as it has alot of ram, let alone require extra swap for each VM too? KVM is still very new, but does anyone know any good books/resources out there? The virtualization books I have seen don't seem to cover KVM, just Xen and others.

VMWare - WinXP As Guest On CENTOS - Networking
OKay here is the set up: I have a CENTOS 64bit running, with 1 guest OS (WinXP) in a VMWare Server. I have tried the following: I have 6 public IP's attached to my 1 Ethernet card in the CENTOS host. Try 1: The Guest OS is set to use "Bridged" Networking. This allows full use of the internet, in both directions. Not exactly optimal, but it does work. I can reach the Guest via RD, which is a requirement for this client. The guest OS is mainly assigned one of the 6 public IP's (x.x.x.118). The problem with this setup is the Guest OS can not reach the host. For example the host has a mail server on it, and when the Guest tries to reach the host, it times out. Try 2: The Guest OS is set up to use "NAT" and gets 192.168.100.128 as its IP via DHCP inside of VMWare. The nat config file for VMWare is set to open port 3389 (RD port). Guest OS can reach the host with out any problem, and can reach the internet with out any problem, however I can not RD in to the Guest OS. I prefer setup number 2 for all the obvious reasons, but I just can not get my IPTables rules to work. This is what I thought should work, but does not: iptables -t nat -I PREROUTING -d x.x.x.118 -j DNAT --to-destination=192.168.100.128 iptables -t nat -I POSTROUTING -s 192.168.100.128 -j SNAT --to-source=x.x.x.118 I realize that would have done all traffic, and defeated the benefits of NAT,but since forwarding only 3389 was not working I tried forwarding everything. Any suggestions?

32 Bit Xen Guest On X86_64 EL5 Node
Let's make this straight, I have this vps,which is pending cancellation in a few days. Hardware Node = EL 5 x86_64, Vz = Xen I asked my provider for 32 bit centos, I even rebuilt it, but my "uname --all" still Quote: Linux xxx.xxx.com 2.6.18-128.1.10.el5xen #1 SMP Thu May 7 11:07:18 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux so I opened a ticket asking about the vps arch. The provider have told me that to run a vps 32 bit guest, what you have to do is (?) +++++++++++++++++++++++++ yum clean all echo i686-redhat-linux > /etc/rpm/platform +++++++++++++++++++++++++ so yum will exclude any x86_64 packages. The provider has told me also that my "uname" display x86_64 because the hardware node is 64 bit. Is this true ? I'm no linux or vps guru, but that's doesnt feel right at all. This has cause me some issues especially with kernel-headers and some program failed to compile. So, is it possible to run a 32 bit OS as xen guest inside 64 bit node?

Xen Update, On Bringing Guest Networks Back Up
After a yum update on a centos 5.2 box (including an update to the latest version of xen) my guests don't have a network connection anymore (nor windows, nor linux VMs). The windows VM does see an unknown PCI device (great, no drivers and no internet), of which I guess is the network card seeing there are no other network cards listed in the VM.

MS Virtual PC - How To Access My Localhost (Apache) Subdomains On Guest OS?
I've just downloaded Microsoft Virtual PC and the Internet Explorer 6 Application Compatibility VPC Image containing an XP installation for testing sites with IE6 [url]. Everything works fine, I chose VPC Shared Networking (NAT) and I can access the internet from the VPC as well as my Apache development server which runs on the host OS (Win XP) by going to the host's IP address which is [url] in my case. And here I have 2 problems: 1. I want to access [url]on VPC just by typing [url]. I added the following line to the hosts file: 192.168.52.141 localhost But this doesn't work. Interestingly, any name other than localhost works fine, for example: 192.168.52.141 localhost.localhost or 192.168.52.141 local This is not a major problem but I'd prefer localhost. Any ideas how to do that? 2. And the more important issue: on my host OS I have some development sites which I have set up to be accessed by subdomains, for example [url], in httpd.conf: Code: <VirtualHost 127.0.0.3> ServerName perfekt.localhost DocumentRoot C:wwwperfekt DirectoryIndex index.php index.html </VirtualHost> and in hosts file: Code: 127.0.0.3 perfekt perfekt.localhost And now I want to access this site from my VPC too by using subdomains like this! How can I do that? The address 127.0.0.3 seems to be local to the OS and VPC can't see it. I have tried setting other IP addesses in httpd.conf but nothing outside the 127.x.x.x range works on either OS. I suppose I need to make each of my sites to be seen under a different IP from the outside network so that VPC (which is "outside" the host OS) can access them - then I just set up the appropriate subdomain names in VPC hosts file -

How Do I Host Windows 2008 Server As A Guest OS On My Linux Dedi
How do I run a virtual instance of Windows server 2008 on my Linux dedi? Do I need to partition the server and create a VPS for this or can I run it on something like VMware? (Please look at my other thread here [url]t=857377 to learn more about my server, its resources and current config.) Why would I want to do this? Because my primary desktop OS is still Vista Ultimate 64 and I've invested a lot in Windows-based software and hardware--too much to make a total switch to Linux. But, I don't want to invest more than I have to in order to run a Windows server that allows my business partner to access documents remotely or for us to share various files securely and privately and still serve my mostly Windows-based clients and colleagues. I'm one of, well, two people I know who even use Linux (at least at the OS level and know it). Since my research shows I **can** do this on Centos 5, the responses that would be most useful to me would be those that focus on how I can do this successfully (even if it seems complicate; I can figure it out with help and/or direction) and what to consider or avoid when creating this virtual guest OS on my Linux dedi.

Conduct Or Legal Operating Practice
I have a ethics and legality scenario I would like to pose here. This is to be considered a fictional scenario and any similarity to any real company or person is unintentional. COMPANY X has colo racks in DATACENTER and hosts a client named COMPANY Y. COMPANY Y also hosts 50 small web sites on cpanel and 40 VPS servers on their linux VPS node in exchange for a discount or other compensation. During the month of may and COMPANY Y's bill raises from being 3000 past due to over 12000 past due to various reasons including purchasing of hds from the DATACENTER using COMPANY X's account, tech work dont by DATACENTER for COMPANY Y needed also billed to COMPANY X's account, as well as BW and rack costs. Seeing this alrming bill by the end of May COMPANY X begins putting pressure on COMPANY Y to pay some invoices as no payments were received during the entire month of may and COMPANY X is also having a hard time paying DATACENTER due to not being paid by COMPANY Y but makes efforts to pay 25% of the outstanding bill in June. Near the end of june COMPANY X has had enough and arrives at the datacetner to attempt to move theritr clients off COMPANY Ys hardware so they can suspend service of COMPANY Y completely. On the visit COMPANY X brings 2 new servers in and begins moving clients of their over and COMPANY X notices this action and begins to suspend and remove access to all of COMPANY X's clients. COMPANY X then decided to power off the boxes of COMPANY Y and removes drives containing COMPANY X customer data for offline recovery. and because they beleived the DATACENTER might be untrustworthy enough to release hardware fromt heir rakcs without their permission. The drives were for as much colatteral purposes as for recoverying customer data. They then pack the drives in boxes and a bag and leave the datacenter having spent nearly 20 hours working and head on a long trip home and signs out of the data center in front of various techs holding the server parts and tools. Upon arriving back to their office/home They were informed that the removal of the HDs was not allowed byt he datacenter because the account was past due and it was discovered that several drives with cOMPANY X's clients were left in the datacenter which COMPANY X now wishes they had remembered to get. DATACENTER is furious and demands the account be paid in full by a fixed time or the entire colo will be cut power. COMPANY X scrambles to find others to help them and another major client who has alot at risk decides to help and a payment of $7160 is made to DATACETNER but it came in a few minutes past the deadline. DATACETNER had suspended servuce, and cut power but stated they wil return service shortly. Shortly after this it is discovered that several servers belonging to COMANY X and two other companies who were supsended in the same day were not int he rack anymore.

How Do I Setup A Ubuntu DomU Guest On A CentOS / Fedora Core XEN Server
how to install Ubuntu (either 7.10 or 8.04) as a XEN domU guest on a CentOS 5 / Fedora Core 8 XEN dom0 server? I have tried installing Ubuntu as a fully virtualized guest, but the Ubuntu CD doesn't even bootup. I get the Linux bootloader, and that's it,it doesn't continue to boot. Odd. When trying to install a Paravirtualized guest, I had to use the debootstrap method, but can't get it to boot up. Quote: xm create anya_zanet Using config file "/etc/xen/anya_zanet". Error: (2, 'Invalid kernel', 'xc_dom_find_loader: no loader found ') This is the xen configuration: Code: kernel = "/boot/vmlinuz-2.6.23.1-42.fc8" ramdisk = "/boot/initrd-2.6.23.1-42.fc8.img" builder='linux' memory = 256 name = "anya_zanet" vcpus = 1 vif = [ 'bridge=xenbr0' ] disk = [ 'phy:/dev/System/anya_zanet,hda1,w' , 'phy:/dev/System/anya_zanet,hda2,w' ] root = "/dev/hda1 ro" on_poweroff = 'destroy' on_reboot = 'restart' on_crash = 'restart' how to get Ubuntu working on a CentOS / Fedora Core XEN server?

Virtualization Platform
In another thread somebody had mentioned something about Citrix Xenserver utilizing shared iSCSI storage with multiple hardware nodes. I think this is a very intriguing concept, but is there anything open source or less expensive that you have used to accomplish similar resource virtualization? Whether citrix or not, describe your setup!

Which Virtualization For Desktop
This is a little bit Offtopic here but maybe it's okay to ask my question. For my GUI software development i need a virtual server solution. It must run WinXP, WinVista, LinuxI386, LinuxAMD64, FreeBSDI386, FreeBSDAMD64 and Solaris. I'm currently running VMWare with all this systems. But their KVM tools are very instable - especially when waking up from hibernate etc. They eat the key/mouse focus and the only way to get any reaction is often a hard shutdown. How good are the other Virtualization Kits? I heared that FreeBSD does not work on VirtualBox? I'm especially interested in Xen but i'm not sure if this is good for Desktop use. Seems that it is promoted almost exclusively as a server solution.

Apache X Virtualization
We usually find some constrains using Apache/cpanel (1.3.41). Basically, we serve simple php codes and few images. We usually setup our server to use lighttpd for static content and apache for dynamic content. Ok, due to some complex requirements on mod_rewrite we use that setup. But frequently we see our apache reaches it limit and slow down with 0 idle servers. Specially as we have about 270 requests/per second on apache. Our load is low, barely passes 1,2 of load for small periods, our memory ok, our I/O is fine. But we almost always reaches the 0 idle servers. Until now, our best config was: Timeout between 60-120 KeepAlive Off MaxKeepAliveRequests 1000 KeepAliveTimeout 15 MinSpareServers 50 MaxSpareServers 200 StartServers 50 MaxClients 256 MaxRequestsPerChild 80 As we clearly see that our server is under usage, I was wondering if it's a limitation on Apache or if I put virtualization on my server and run two apache webservers as cluster I would get better results. So what do you think about guys? It's a matter of optimization (what could I do better for this httpd.conf setup?) ? Or cluster with virtualization would deliver what I'm looking for.

Virtual Iron Virtualization
Basically I need to virtualize a single new dell server. One virtual server needs to run windows 2003 server standard and Microsoft SQL 2005. The other virtual server will run CentOS Linux with a perl and PostgreSQL application. The dell server is going to have two quad core xeon processors (8 cores total), 8gigs of ram, and two 15,000rpm SAS drives. I came across Virutal Iron which is free for the single server instance and seems like it will do the job well. Has anybody used it? What is performance like? Seems to run a Java backend so wondering about the performance there. Any other recommendations? I looked at VMware but the cost is so high, and probably more then I need, since I only need to virtualize a single server.

Virtualization Solution? VMware, Virtuozzo, Xen..?
I'm running a dedicated server and the main site on the server relies on Windows OS. The site is not fully utilizing the potential of the dedicated server, so I'd like to put some of my other sites on the same server and eliminate the other (shared) hosting I've been using. Here's the catch... For the other sites, I'd like to run WHM/Cpanel which requires Linux. If I understand correctly, this leaves me with having to decide on a virtualization solution, which I know nothing about. Some options I have been given are VMware, Virtuozzo, and Xen. Would you suggest one of these or a different solution entirely?

Virtualization --48Gb @ 1333Mhz Or 72GB @ 800Mhz
So when buying nehalem servers, if you populate 6 rdimms, you can run at 1333Mhz, if you populate 18 rdimms, 800 Mhz (12 rdimms, 1066mhz) So what do you do for virtualization? the reality is most of the time 48gb is going to be enough for virtualization (that would run 12 4GB servers or 32 2GB servers) and i think at 64gb or more, CPU starts to become a limting factor, but the price of 48GB @ 1333 is slightly more than 72GB @ 800. So what are you guys doing out there? do you go for the performance or do you go with the overkill of memory (that might sometimes come in handy but you probably wont use it all -- more likely just give your VMs more memory for the fun it)? The problem is the 1333 Mhz vs 800 Mhz performance. Our current environment is a bunch of 16GB servers (50xx chip) and the limitation on us virtualizating more per host is the memory. So I know 48GB is going to be very much welcomed and I think we could use more.. 64gb would be ideal, but we will be happy with 48@1333, but 72GB sounds interesting too, there might be some scenarios where we could use that 72GB although i think performance will shift from memory limitation now to CPU Do you think if we buy 800Mhz 72gb we will ever look back and think "wish we bought the 48gb 1333 rdimms and not these 800mhz ones"?

I Have Lots Of Bandwidth, But My Host Is Slow - Should I Pay For Virtualization

Although my sites do load and I get unlimited everything pretty much, I can't stand the slow loads. They have offered me virtualization of my server so I can create my own virtual server with 150Mhz and 150MB of dedicated CPU/memory for $15 more a month... do you think that will speed me up a lot or should I just suck it up and pay for a better host that doesn't pimp themselves out so badly?

Virtualization - Enterprise Installs? VMWare, Xen, Virtual Iron?
A company i am working with is looking to install a VMWare setup comprising of something like this : 6x Dual Proc Quad Core Nodes with 16GB RAM 2x Clustered iSCSN SAN Nodes I am intending on purchasing the full suite including DRS/HA/VMotion. Now this is all well and good but the software pricing is absolutely horrendous! So my question to you chaps is : Is anyone using the latest Virtual Iron or Xen Enterprise in a high end environment? Obviously VMWare is the market leader, the big boys are using it and its something you can bank on. (literally! HSBC use it ALOT!) Is it even worth looking at VI/Xen for something like this? The cost would be like a quarter of the total cost of a VMWare license.

Dedicated Or Reseller Setup With Virtualization Or Decent Chroot Setup
As my clients' needs expand, they're asking for chroot ssh/sftp setup. I'm currently on a dedicated Linux setup but don't really have the time to set up a whole new box with full virtualization or investigate a full chroot solution (baby on the way), and to be honest it would be less hassle to move to a new provider than worry about down time with sites. What I'm looking for: - linux hosting - hosting for 30+ accounts, some with several domains - at least 6 IP addresses for SSL certs - each account in a full chroot environment (ssh/sftp/ftp) so they can't poke around each others' files, or each account set up in a virtual machine setup (ie: openvz) - maildir - spamassassin - php 5, mysql, perl 5.8.8 - suexec apache would be nice

KVM Over IP System
I have a few different types of servers, all of which came with their own KVMoIP setup, aka DRAC and iLO which have worked only so so since their deployment. The HP iLO has performed absolutely flawlessly but the DRAC on the other hand has been nothing less than a complete nightmare. I'm looking for a KVM over IP system that we can connect to multiple servers, mainly Dell, that is 100% reliable and completely stable. Not something that will be giving Java errors randomly when you actually need it to work. So far I've came across the Raritan Dominion KX II which looks pretty promising. Is there any other KVM over IP systems or manufactures that I should look into? Has anyone used this and can you comment about its reliability?

What you guys suggest as backup method, maybe some how-to backup WHOLE system with all files, raid configuration etc. I dont need incremental backups at all - I just want to save/backup current system, and maybe restore if something bad would happen.
