Ubuntu :: Build An HTPC Using Clustering?
Jun 16, 2011
I'm trying to get an HTPC going, but I don't have any money to purchase a new computer. I have 2 desktops in my possession that I am trying to use: 1 is a 2.4 GHz with a 128 MB Radeon 9800 PRO video card (I think) and 1.5 GB RAM (the system is about 8 years old, but I built it top of the line for back then). The second system is a 3.2 GHz dual core with on board video and 2 GB RAM.The problem is, neither system will run 1080p video's without dropping hundreds of packets producing very choppy audio/video. I was wondering if it is possible to cluster these two systems together to harness both their processing power to run 1080p video? I would just jump in and attempt it, but as I have been reading, it looks like processes aren't actually shared across PC's, but auto determined which PC it will run on based on load, which is an issue since neither can cleanly run the 1080p video.

I am looking to build a simple HTPC based on boxee, it is a very low power machine (2ghz P4, 1gb RAM, 1gb video card).
At present it has Win7 on it, but I want to run boxee as my media centre software (I love the watch later facility) and I was wondering what it would run best on?
If linux, what distro and why?

I am building a Home Theater PC. I know for sure I'm using Ubuntu, but what version?For one I have never put any type of Linux based anything on a computer. I have been told by countless friends that Ubuntu is my best choice for this and have used it on a pals pc. I like it.I did my research and came up with 3 main choices: Ubuntu Desktop, Xubuntu and Ubuntu Netbook Remix. (but not limited to those)The only reason I added the UNR is that I need something with a easy interface.

I have a custom built PC with a AMD 9650 2.3ghz quad core, 4gig of ram, nvidia geforce 9500gt graphics card. With windows 7 my movies look immaculate but I want that from Linux. My first problem consists of lines in my players. To test out the performance I am playing Final Fantasy 7: Advent Children Complete Blu-Ray. The video file has been ripped and placed on the HD. MPlayer has lines everywhere, VLC is very good but line every once in a while, XBMC plays bout as well as VLC. The first part that confused me was how MPlayer was worse off. I have followed all the stickies and this is a fresh install of ubuntu 9.10. The Second problem I am having is getting my onboard audio to work. My board comes with 8 channel audio support but my 2 side/back speakers wont work. I have messed with the application settings and the actual settings in Sound Preferences.
Here is a link to my board specs

My current project environment setup is having a single server, running on RHEL 5.2, that is constantly receiving incoming data (video and text) over a periodic interval e.g. every 30 minutes. Initial in-house testing projected the server will be generally busy, so we decided to incorporate a second server for load balancing purposes. So now, server A and B will need to be clustered. Once that is done, incoming data will balance out between the two server (or at least that is what I will like to achieve. Note, I'm aware that at the switch side, I'll need to do some additional configuration and that part is covered).
I've been reading on Red Hat Cluster Suite and the Linux Virtual Server (LVS) seems the way to go. However, I noted that the LVS solution require at least a two-tier solution, and that would incur 3 additional servers instead of just 1. So here's my questions:- I looked around and probably know the answer, but I'm gonna ask anyway. Is there a one-tier solution for LVS i.e. have anyone tried or whether it's even feasible. From my reading, it don't seem so but just want another opinion. Is there any other way for me to do the clustering (for load-balancing) without LVS?
Sidenote: I'm currently looking at Ultra Monkey and will be trying out in a while. However, the project I'm doing would be rolled out to live site eventually, and my customer is kind of....particular. I'm just wondering if there's a software/application (that need to be purchased) and comes with support.

I am trying to figure out ho to setup EC2 clustering. I am seeing heartbeat as an option. I need something that will monitor the state of a daemon, and not if a daemon is running. For example, say I want httpd to be high availability. Does heartbeat monitor if httpd is not in a hung state, or does it simply do a ps -e |grep httpd? So my question is, how does heartbeat work?

I'm in the process of building a PC to run Ubuntu 10.04 and I want to use it (eventually) to with Direct TV. I just want to be able to use the PC as the DVR if possible. I'll accept the limitations, but I'm trying to do my homework to make it as easy as possible to use for my family.
I've started out with a BioStar M32 Micro ATX board and an Intel E5300 Dual Core Pentium 2.6Ghz processor, with 2Gigs of Kingston RAM. It runs pretty well, but I've got nothing installed yet (I'm dual booting with Windows Server 2003). Right now it's just in an old E Machines case with a new 500Gig toshiba SATA drive.
Is there a guide to what hardware I could get to work with Direct TV? Also, I'm not sure of what all is possible as far as integrating the two. If there is a guide, please let me know. Also, I would love to hear from anyone who is able to network or use Ubuntu with Direct TV.

I wonder if this is possible/easy/practical to do in Ubuntu: I want to have one computer serve two sets of monitors and inputs in two different (adjacent) rooms. The computer and one monitor will be in my office for desktop use, and a HDMI cable to my TV on the opposite site of the wall (I already have a hole for the cable) will serve HTPC content.
I assume I will need two videocards. But other than that, is this fairly straight forward, or is it difficult?

I am building an HTPC based on Mythbuntu and will also have a laptop running Windows.
I need some software that will provide two-way syncing between these machines:
1) Sync folders from HTPC to the laptop
As the laptop is new, all the media content I want to have on the laptop (music and photos) will be on the HTPC.
2) Backing up content from laptop to HTPC
New content (purchased music and photos) is likely to be added on the laptop initially so I'd therefore like to sync (instantly/automatically if possible) this back to the HTPC to make it available there as well.
Does anyone know of any good software to do this?
I'd originally been thinking of DropBox but, as I understand it, you have to use a DropBox folder however, on the HTPC, music and photos will be on different drives and it seems that putting symlinks inside the DropBox folder is not recommended.
This post also talks about using Ubuntu One. I think there's a Windows beta version available but does this sync between machines on a local network as I thought it was a cloud storage solution and I'm not looking to upload any content to the internet at this stage.

I am looking to build up a HA/LB linux cluster with specific software requirements. For hardware, I have a number of dual xeon PE 2650s and would like to use them as efficiently as possible. These are 32bit systems, I anticipate scaling up to 64bit systems when I have a tested, working solution in place. For distro, I am familiar with CentOs, Gentoo and Ubuntu but unsure as to which would be the best foundation, although leaning towards CentOs. For software, I need to realise all the services provided by xampp (Apache, MySql, PHP, Perl, FTP), plus Red5 flash media server.
My current train of thought is;
6 physical servers; 2 Directors/Heartbeat, 2 Apache, 2 Red5
Gigabit private network for connecting the nodes.
CentOs 5.5 on all nodes.
DRDB across the 2 Apache nodes for Apache, MySql, PHP.
DRDB across the 2 Red5 nodes for Red5.

I added the "@clustering" and "@kvm" keywords to my ks.cfg file but during installation, an error about not being able to find either of these packages popped up and it wasn't installed.
I do see the Cluster and VT directories in my redhat_es5.4 directory along with the Server directory. The rest of the files install just fine.
In doing some net and forum searching, I find a reference to a base.repo file that lists the directories but I'm not sure if it's related to creating a yum repository or if not, should it have been created in the redhat_es5.4 directory.
While I've built kickstarts for several years and am comfortable with the file, this is the first time I'm working with rpms outside the main Server path.

I'm planning on setting up a home file server. I was wondering what platform would be recommended for something like this. The server would be used mainly for media storage which would be shared between an HTPC and a couple desktops and laptops. I was thinking of just getting whatever motherboard had the most SATA headers on it (which currently seems to be something P55-based) and setting up a RAID5 fakeraid with some 1.5 or 2TB drives and the OS in RAID1 with whatever drives I have laying around. It there anything flawed with this approach? P55 boards with 10 SATA headers are currently upwards of $200, which is kind of pricey. Is there a more economical route that I should consider? Also, are there any known problems with setting up a fakeraid like this using certain motherboard's SATA controllers?

I'm looking to set up a clustered mail server, I kind-of know how I'm going to do it but wanted to check if there was a better way. So we have 3 mail servers, running as EC2 instances on Amazon AWS. We were going to achieve clustering by giving all three a shared EBS storage device to store the mail. The mail would be received by any of the three servers (Via postfix) and could be retrieved from any of the three servers (via dovecot). For receiving mail (SMTP), the domains would have 3 MX records pointing to each of the servers but for sending and retrieving mail (SMTP and POP3/IMAP) the three servers would have one DNS A record with 3 IPs associated (I know when using this method for web-servers, the load gets distributed among the IPs under that record but I'm not sure if this will work for SMTP/POP3/IMAP).
What we want is to have 3 servers that share the load equaly but are completely redundant for all services (POP3, IMAP and SMTP). We also need to be able to scale upwards so if we need to add more servers we can do easily. Also the servers must be perfectly synchronized at all times.

I have several computers all running Windows XP except for an older Compaq DC5750 Desktop which will become a HTPC. It's a decent machine with a Athlon 64 X2 3800+, 4GB DDR2, 1000 MHz FSB, 4 empty PCI slots, and is extremely quiet. So, I'm going to use this project to 'get my feet wet' before taking the plunge.

What kind of tuner I need. do I pick up ntsc, atsc, or something else? My cable comes from the wall to the tv, there is no box receiver.
I have had real bad luck with the acermedia duet and the hauppage hvr-1250. Aperently, the aver duet has 0 support and I can't get the hvr-1250 to work. I'm running mythbuntu 10.04. I can't even get avi's I downloaded to play in mythtv.

I have an HTPC with an onboard ATI video chipset but for hardware acceleration's sake, I installed a GeForce 9500GT video card. Everything works quite well, except for the overscan issue. I've installed the latest nvidia binary drivers (manually) but I don't see any options in nvidia-settings to solve this overscan issue.
Here is my xorg.conf file:
Code:
# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig: version 260.19.21 (buildmeister@builder103.nvidia.com) Thu Nov 4 20:57:26 PDT 2010
Section "ServerLayout"
Identifier "Layout0"
Screen 0 "Screen0"
[Code]...
I tried adding that ModeLine line myself (using xrandr and gtf) but that fails too. I've scoured the web and these forums, and I've seen some overscan issues reported but with no solution in sight.

I'm extremely new at Linux but managed to get Alsa .023 installed on my HTPC and sound working in xbmc. However, every 10-15 seconds when playing audio over HDMI, i get a short burst of static (maybe 0.5 seconds). The static does not interfere with the audio track. I have tried running my laptop using the same cable/tv/port and its fine (win7). Listening through the analog connection on the mobo with headphones produces no such noise. The noise happens with any audio such as ..... or xbmc.

I'm very new to linux and would like to build a 64-bit file server to backup my pc and laptop, I would also like it to have HTPC capabilities because it will be stored in my "man cave", where me and mates seem to hang out a fair bit. I've never built an AMD system before and would like this build to be AMD.
This is what I've come up with so far:
64-bit system:
Case: Thermaltake V3 with 450W PSU
CPU: Athlon II x2 255 3.1GHz
Mobo: ASRock 880GXH-USB3
HDD: WD Green 500Gb for OS, 2x Samsung EcoGreen 2Tb for storage (one will be kept off site)
Memory: 1x Corsair CMV4GX3M1A1333C9 4Gb DDR3
[Code]...
I'm not sure about all this being compatible with linux, like the tuner, but I have read that you can get this working. I'm on a pretty tight budget so I can't upgrade to higher end components, but would like suggestions on components where I could save a few $$ or if any of these components are overkill.

I'm looking at getting a Seagate Barracuda LP 2TB drive for my HTPC. However I was initially looking at the WD Cavier Green due to it's power saving features. Upon finding out about the Green's problems interacting with the Linux Kernel I have ditched the idea of getting a WD.
Does the Barracuda suffer from similar problems as the Cavier Green.Are there any problems at all with the drive and the kernel not playing nice together? Do I need to set anything in the kernel config to help enable power saving features of the drive so that when the PC is not in use the drive uses as little power as possible?
