Server :: Building The System Isn't A Stumbling Block?
Oct 4, 2010
my workplace is switching from Oracle app server to Tomcat. I've never been a sysad, and never administered an app server. So that part is going to be completely new to me.ortunately, I don't have to be the primary on this - but my manager is encouraging me to learn the setup and how to do the job.So, my situation is that my test "server" is a P2 with 256MB of RAM. I know I'm not going to get screaming performance out of it, but all I really need it to do is run my web server and file server to support my Tomcat install on a separate box (P3, 2.8GHz, dual-core with a gig of RAM).
I'm not really a n00b to Linux, so building the system isn't a stumbling block. Which distro, and which version of that distro, is a stumbling block. I know ubuntu is easy to set up, and very popular. If I went that way, should I get the desktop version? Or the server version? I *want* the GUI, but don't require it. And I'm not real certain what they're referring to (hw or sw) when they call it "desktop" or "server".I'm not looking for a challenge to broaden my horizons in terms of my Linux knowledge - I just want something I can set up quickly so I can get on with learning what I need to about the server installation, configuration and administration.
I am trying to build a system that will run both KDE and GNOME. I currently have just GNOME installed. So I need to install KDE and KDM (which I know how to do). The thing that I don't know how to do is make it default to KDM when it boots rather than GDM. Also I need a way to get rid of the GNOME apps in the menus in KDE and the KDE apps in the menus in GNOME. Also, this system in running Fedora 11 x86_64
I've decided to build a new system. I been doing a lot of compatibility searches with little luck. I don't have a bunch of money to put into it but here is what I've been looking at. I have been very happy with Ubuntu 10.04 lts Lucid 32-bit version and thought I would install the 64-bit version on this. I would like your input on this system. Are there any compatibility problems here?

Along with this I have 1-Sata 500G and a 1-Sata 250G hard drives that will be installed.
Looking at building a system that basically just runs emulators (nes, snes, etc). Haven't messed around with linux for a couple years so I thought this might be a great project to get back into it with. Maybe.
Questions I have- - How easy is it to have a linux installation that just boots directly into the emulator? Since it will be hooked up to a tv, I just want it to be as easy as turning on the power button and then I'm off. - Is there a stripped down linux distro that would be best suited for this type of setup? Really any recommendations for a distro would be great. - Its running on old hardware- 900mhz athlon, 512mb ram, geforce2 video. Will this be a problem if I'm trying to run something like i've described?
In 2010 I want to build a new linux box. I currently have a dual-boot system... IDE1 = WinXP 200GB Master IDE1 = Opensuse 11.0 Slave 80GB
I have cloned both drives with CloneZilla (CZ) and restored with it aswell. My 80GB is a Western Digital Caviar Model (WD800BB-00JKC0). The drive I'm thinking of buying is a WD Caviar SE (WD800AAJB) [URL]. Will my restore images work with this drive? Its a 80GB but the model numbers differ. Does it make a difference?
So far my experience with Ubuntu has been using it in Virtual-Box and as a Live CD and Live-USB. I currently have laying around a CPU/GPU/PSU so i bought the rest missing to build a new computer. I got two hard drives (640gig for Win 7 & 80 gig for Ubuntu). I have been told on [H]ardForum . com to use WUBI. That its not necessarily great for long term usage, but its best to use WUBI, get the hang of Ubuntu and dual booting and all that...and then eventually to try a more permanent solution.
For now i am curious is there anything i should know before I start? I bought Win7 64bit so i want to use Ubuntu 64 bit as well correct? Are using WUBI and going into the Boot-Menu and starting using the 80gig HDD with Ubuntu on it, two different options? If so which is better in your opinion?
Btw to install WUBI , do i install windows, put in the CD and click install WUBI which auto pops up, and follow directions and just make sure to have it install Ubuntu 10.04 64bit on the 80gig hard drive?
One last thing, i have seen screen caps of a menu (that looks like a boot menu before you enter your OS) that has options like "use memtest to test your memory" and "Check Ubuntu CD for errors" ....how do i get to that? I would really like to be able to do both of those things.
My parents have given me a free pass to play around with their old Saab 900 Turbo and what I'd really like to do is put a small linux computer in there as an experiment (and application, ultimately). For this to be a realistically useful project I really should make it interface with all the cars sensors and controls e.g. speedometer, fuel gauge, mileage, thermostat etc. I assume that since these are analogue meters they use an electromagnetic dial? It should be possible then (and without too much effort) to hook it up to an input device like the Arduino? I don't really know because it's been a long time since I studied electronics properly. I've already found a touch screen, I'm fairly sure I know what computer I'm going to use (SheevaPlug) and I'll probably use debian with xfce for the OS.
I installed the minimal-command line system from the kubuntu CD on my laptop, which is guess is roughly around 200mb after installation. I wish to install a Desktop Environment preferably KDE and I wanted to know how and where do I begin from? Do I need to have a working XORG prior to installation of KDE and do I also need to install Window mangers and e.t.c? What all packages/libraries and components do I need to install first? I'm really not sure where should I begin from.
Initially what I am trying to do is to have working GUI system,then later on I can install rest of the packages and software that I need, like office, GPU drivers, browser etc. Secondly,for a minimal KDE system,what metapackages are to be installed from this site? I believe kdebase, kdebase-runtime, kdebase-workspace are required. [URL]
My Redhat Enterprise Linux 4 with 6x partitions (/, /boot,/home, /usr, /var, /tmp) of 6.0 GB IDE Hardisk was working quite fine. I decided to create LVM on /home and /var partitions but due to some errors occured and I delete the /home partitions. That's why partition table altered. I then delete 4,5,and 6th partitions (/home, /var, /tmp) partitions and now try to create one by one but following error is coming:-

The Super block could not be read or do not describe a clear ext2 file system. E2fsck b 8193 <device> I have tried following commands,but could not successful:- e2fsck -p /dev/hda7 (where hda7 was created but afterthat it was deleted) e2fsck -a /dev/hda7
I have been playing with chroot to build packages.I am wondering about the limits or caveats of using chroot to mix operating systems. For example, what should I beware if I use 12.2 and chroot a 13.1 system? Or if I use 13.1 and chroot a 12.2 system? After all, the chroot does inherit some attributes of the parent system.There is the noticeable difference of kernel versions. For that one reason I'm thinking that mixing system versions might be frustrating.
My focus is building packages, not running an alternate operating system or a service such as ssh. I realize that building packages as root in a chroot potentially compromises security but that is not my focus.I am aware that a chroot is not a true virtual system.A virtual machine is an option, but in this thread I'm curious about the limitations of chroot. I find building packages in my virtual machines much slower than actual hardware, even with a dual core. Hence my interest in chroot
I am trying to figure out the best server configuration for the following:Low power (I want to plug the server in and forget about it)High redundancy of data (I don't want to loose my music and documents!)The ability to stream music + movies to laptop (maybe subsonic or Jinzora)VPN server with IPsec or OpenVPN NAS $800 budget 2TB with ability to add more drives :Unix Server with software RAID (maybe RAID6)
VPN setup on virtual OS via VirtualBox NAS setup on virtual OS via VirtualBox
My Questions:What would be the best raid configuration if I wanted at least 2TB of data and the ability to add more disks when the space begins to add up?What would be the best OS to use for setting up a software RAID (is a FakeRAID a better solution)?Does it make more sense to separate the VPN and NAS with different OS's?My goal will be to access my data from any computer from anywhere but mostly just my Laptop from work.
was originally looking to setup some kind of NAS in my house due to the fact that me and my wife both access the same music libraby, photo library etc. and was looking at one of the IcyBox enclosures.I realised that whilst this was a quick and possibly easy way to set something up, it wasn't in keeping with the true geek within so decided to look into setting up a full RAID5 file server. This would then allow me to install and setup various other services such as Web and FTP server, Mail server and DNS server should I ever want to.
I have an old machine (Duron 1GHz I think) with 1GB ram but the only problem is that is doesn't have an on board SATA controller so I was wondering what PCI SATA controller cards work with Fedora? Doesn't need to have RAID capabilities since i'll be using Software RAID anyway, just need a nice cheap Fedora friendly controller card that'll do the job.
I've been running my dedicated server on Ubuntu 10.04 for 300 days non-stop so far (touch wood). I'm planning to purchase a dedicated server to host many large sites. The specs are Sandybridge Xeon with 16 bay x 2TB storage using RAID5 (Adaptec RAID 51645).I don't have experience with RAID, but I read that ext4 can only support filesystem up to 16TB, my plan for the system is to have 32TB of storage. How can I make Ubuntu run this configuration?
Also, can Ubuntu 10.04 recognize the Adaptec card? Going through Adaptec website there is no mention of drivers for Ubuntu (although many other distros are available).
I have builded my kernel through wiki manual, BUT, the kernel-headers rpm-package has not been builded. Now i have only two packages: kernel and kernel-devel. Is that ok? (i think, that it is not ok, because when i build the same version of kernel on x86_64 platform, after rpmbuild command i have kernel, kernel-devel and kernel-headers packages) My CentOS version is 5.2; platform i686; kernel, kernel-headers, kernel-devel packages 2.6.18-92.el5.
Does anyone know where I could find a block diagram of the Squeeze sound system with all the possible permutations thereof. I am primarily interested in OSS4 on a KDE4 desk top. I want something that shows all possible inputs, all possible outputs and all of the component programs in between. At this point I am really confused by all of the possible packages and how they interact with each other.
My present OSS4 installation works with oss4test, VLC, etc. but doesn't work with iceweasel. I have installed all of the recommended packages to no avail. I have an Intel DP55KG mother board with the Intel HD sound system on board.
Is there a program like peer block for ubuntu? It is an ip filter program. Here is the website to help answer questions on what type of program it is. http://www.peerblock.com/
While building my new server I grinded ta hold shortly after inserting the FDR10 DVD.
Hardware: Chenbro es34069 Albatron KI690-AM2 AMD Athlon X2 64 4850E IDE 2.5" HD (master) IDE Slimline DVD (slave) 4x SATA II swap (still empty)
It stops at the message "net: Registered protocol family 2" but in one of my desperate attempts I changed almost every setting in my BIOS (updated to 1.07) and all of a sudden it passed on. Stupid enough I figured it would be a small effort to find the setting and figure out the problem, so I changed them one at a time after loading the defaults....
i want to build server ; for blocking porn site and adult content through my netbook.can someone please give me instruction for building that server using netbook?
my SheevaPlug just died, and I need to look for new device to replace it. My goal is to build a fanless, low power consumption, linux server. Currently I am thinking of purchasing a QNAP NAS device (TS-110 model) and installing Debian on it.
I have 50 identical workstations that are being dropped shipped from the vendor directly to the remote locations. I need to install a identical configuration, including installed packages, scripts and customize configuration onto each of this workstations. I cannot set up a kickstart server to install from remotely because of my organizations security policies. Not to mention that it would be painfully slow. I thought about DD-ing my "Master" build and sending it to the remote sites, but some of the admins are not very Linux savvy. I would really like to build a bootable DVD that would install the cloned Master build from my server to theirs. I was looking for something that would look like Anaconda to the person installing the image. If I could get them through this base install I think it would be easy to document how to change the workstation unique parameters or value. How to accomplished this? BTW, this will be a RHEL 5.3 server install.
I have installed proxy server on ubuntu.I have done every process which is needed to establish proxy server.internet is also working fine through proxy but the sites which needs to be blocked it is not blocking.it is opening.I have made entry of sites which i needed to be blocked in block_dstdomain file in proxy
algorithm:breada input: file system block number for immediate read file system block number for asynchronous read output:buffer containing data for immediate read { if(first block not in cache) { get buffer for first block if(buffer data not valid) initiate disk read } if(second block not in cache) { get buffer for second block) if(buffer data valid) //line 1 release buffer else initiate disk read //line 2 } if(first block was originally in cache) //line 3 { read first block return buffer } sleep (event first buffer contains valid data) return buffer }
Here is an algorithm for block read algorithm. I have problem in line 1: If buffer data is valid why is it releasing the buffer? line 2: If buffer data valid why is it initiating disk read. It should have read directly from buffer? line 3: It should be the first condition as if it is there in cache then it should return it without delay?
I need some advice or tips or maybe your own experiences about building a home data storage or NAS.Here's some thoughts / requirements I think it should have:It should expandable. I'll stick a couple of 1TB HDDs and a little later I'll stick some moreIt should easily integrated to both Ubuntu and Windows 7. Ideally it'll be an integrated part of the filesystem.I'm thinking some sort of RAID as a backing up my data. RAID 1 seems like a such a waste but then again, these days, HDDs are cheap.And when I do add more HDDs, I'd like them to appear as one big storage unit instead of separate drives.Any suggestions and tips on how to go about this is welcome. Questions are plenty: should I go with server hardware or is bigger ATX case and standard hardware enough? I'll need some pointers so keep 'em coming
I am looking to build a dedicated syslog-SNMP server with remote web interface and I would appreciate a discussion from our community on recommending the best solutions to deploy. I would like to be able to create an opensource architecture I could easily duplicate for multiple stand-alone customer environments.
I have an old tower that I've installed Ubuntu onto. It connects fine online with a mobile broadband stick. I also have an old wireless router knocking about, and I've been trying to network up my house wirelessly using the tower as a router, if that makes any sense. Long story short, this is my setup
Internet ==> Mobile Broadband ==> Tower ==> Wireless Router ==> Wireless Devices.
I know that it's complicated, but I'm sure that it can be done. I've tried playing around with bind9, and playing with dhcp and the like. I feel that I am close.... but no cigar. how to route all traffic from the router
I had found the following error messages one of my Linux server. the file system using for this partition is EFI GPT. Is this cause because of RAID controller incompatibility or Driver mismatch? PHP Code:
I don't care so much the practicality and needlessness of actually setting up a computer for proxy server for personal usage, but none-the-less, i want to do it, and i'm just wondering about hardware.The proxy, i don't intend on having a desktop environment, so it'll be a terminal interface.But for a system that will handle traffic for 3 pc's and a ps3, how much hardware would one suggest i need, as far as RAM, HDD space, so on and so forth.
I was thinking it would be fun to do with with my old amd k6-2 processor and it's 32mb of ram, but in order for that pc to work, i'll need to replace a few hardware pieces, and before i dumb money into it and pull it out of the closet, i want to find out if it would even be worth my time to do it.
