• How to configure VirtualBox server for performance at home

  - by BluJai

  I currently have two physical Ubuntu Server 10.10 servers at home: one serves as our firewall/router/DHCP/VPN server and the other performs double-duty as a file server and a VirtualBox host for an Ubuntu Desktop 10.10 machine which I use from remote connections (via NoMachine) for many thin-client purposes which are irrelevant to my question. What I'd like to accomplish is to consolidate the two physical machines into one which is a dedicated VirtualBox host (most likely running Ubuntu Server 10.10). Note that I'd like to stick with VirtualBox (if possible) because I'm most comfortable with it and use it on a daily basis at both home and work. Specifically, I plan to have one VM set up as file server, another as the firewall/router/DHCP/VPN (or possibly split those a bit) and a third, which is the only current VM (already VirtualBox), which is the thin-client host. My question comes down to performance and/or recommendations about the file server VM. The file server hosts about 6 terabytes of data across 4 drives. What I'd like to do is use raw disk access from the VM directly to the existing disks. However, I'm curious what performance advantage/disadvantage that would have as compared to using shared folders from the VM host and basically just have the whole drive served as a shared folder to the VM which would then serve it to the other machines on the network. I don't know if virtual disks would even work in this scenario and I certainly wouldn't want a drive to be filled with just a single file which is 1.5 TB (disk image). To add understanding of context, but not to get additional advice, I want to virtualize these machines because I intend to regularly use the snapshot capabilities of VirtualBox for the system disks (which will be virtual drives) of the VMs and I have some physical space/power needs to address (as I mentioned, this is at home).

• Java Swing over Remote Desktop - Strange, weird GUI squashing

  - by ADTC

  I thought this question fits SuperUser more than StackOverflow because it's not about actual Java programming, though programmers might be more likely to encounter the problem. Anyway, let me start of with some stats before I ask the actual question: Laptop: Windows 7 x32 Screen resolution 1024 x 768; Nvidia GeForce Go 6200 Connected to desktop via ad-hoc wireless network Access internet via desktop Desktop: Windows 7 x64 Screen resolution 1920 x 1080 Connected to laptop via ad-hoc wireless network Access internet via cable modem I'm connecting to my laptop via Remote Desktop from my desktop to take advantage of the large screen. I'm doing programming on my laptop (for portability reasons). Everything else runs smooth and fast over Remote Desktop as both computers are connected directly over the ad-hoc wireless. The only problem is this: Java Swing apps don't display the GUI properly. I acquired a Java Swing application and I'm debugging it in Eclipse. Here's what I got when I ran the app: Apparently there doesn't seem to be anything wrong with the GUI application I'm debugging, because the Java Control Panel exhibits the same problem. I've searched high and low in Google about this; the closest I came to a solution is this. But sadly, the use of -Dsun.java2d.nodraw=true has no effect at all. This only happens over Remote Desktop. I have tried locally and the GUI apps display properly. This isn't a dealbreaker for me as I can stop using Remote Desktop when developing Java Swing apps. However, I would like to know if anyone has encountered this and found any solution. PS: All software involved (Eclipse, Java JRE, etc.) are latest versions.

• Why a 10 years old software still is so slow even today?

  - by Cawas

  I just noted this question due to a game (which happens to be Diablo 2), but the matter of fact is: why is my brand new mac book pro, made in 2009 with latest technology (tho it's the cheapest one) can't rival my computer which used to run this much faster back in 2000? Really, it was much faster on my AMD K6 450 back in those days, and I could even run two clients at same time with no slow down. I've always had the feeling this machine was slow, but this is a very odd way to attest it. Granted, the machine is smaller, runs on wifi and "boots" way faster thanks to sleep mode. But other than that, what have we evolved after all?! I'm pretty sure this shouldn't be graphical card's fault. Sure if I buy latest technology it will run fast, and probably most people here can confirm this and won't even understand my question. But the thing is, all the hardware is supposedly much faster and better than the stuff from 10 years ago. The software and operating system became more complex, but also more well refined. Now I'm trying a piece of software that is actually 10 years old and it's not getting any better results! Why?

• how to design pound -> varnish -> jboss for ha + loadbalancing

  - by andreash

  Hello, I'm planning a new infrastructure for our web application. We have two JBossAS5 servers, running in a cluster. Session state will be replicated via JBoss Cache. In front of that, there should be some cache, to speed up delivery of static elements. However, most of the traffic to our app will be via HTTPS. So far, I had been thinking of two Varnish caches in front of the JBossASs, each being configured for loadbalancing to the two JBossASs via round-robin. Since Varnish doesn't handle HTTPS, then there would need to be two pound proxies in front of the Varnishs, dealing with the HTTPS. The two pounds would be made high-available with Heartbeat/LinuxHA. The traffic to www.example.com would then be going through our firewall, from there to the virtual IP of the pounds, from there to the Varnishs, and from there to the JBossASs. Question 1: Does this make sense? Or is it overly complicated, and the same goal can be reached with simpler methods? Question 2: If my layout is fine, how do I configure the pound - Varnish step? Should I a) make the Varnish service high-available through Heartbeat/LinuxHA as well and direct traffic from pound to the virtual IP of the Varnishs, or should I rather b) Configure two independent Varnishs and use load-balancing in pound to address the different Varnishs? Thanks a lot for your insight! Andreas.

• PC only boots from Linux-based media and won't boot from DOS-based media

  - by xolstice

  I have this problem where the PC only seems to boot from a floppy disk or CD if it was created as a Linux-based bootable media. If it was created as a DOS-based bootable media the system just freezes at the starting point of the boot process. I originally asked this under question 139515 for CD booting only, and based on the given answers, I was under the impression the problem was with the CD-ROM drive; however, I have since installed a newly purchased CD-ROM drive and the same freezing occurs. This then made me try the DOS bootable floppy disk approach and I was quite surprised that it exhibited the same freezing problem. I then tried try a Linux bootable floppy and everything booted from it without any issues. As I mentioned in my original question, the PC was booting just fine from the DOS-based bootable CD, and then it suddenly decides to pull this freezing stunt. I can't remember if I changed anything in the BIOS settings that may I have caused the problem, but I am wondering if that could be the case - it is currently using the Award Module BIOS v4.60PGMA. Can anyone help?

• SSL stops working on IIS7 after a reboot

  - by Mark Seemann

  I have a Windows 2008 Server with IIS7. Every time the server reboots, SSL stops working. Normal HTTP requests work fine, but any request to an HTTPS address gives the typical error message in the browser: Cannot find server or DNS I can temporarily fix it by opening IIS Manager and bring up the Bindings… window for the website in question. Then I select “https”, click on “Edit” then click “Ok” without making any changes to the settings. After doing this, browsing to https:// works again until the next reboot. This issue look as lot like the one described here, but according to the Certificates MMC snapin, the certificate in question does have a private key. I'm also pretty sure that I never installed the certificate in the personal store, but imported it straight into the machine store, but it's been a while... There's not a lot in the event log apart from the event ID 36870 also described in the post I linked to. Can anyone help me troubleshoot this issue so that SSL will work even after a server reboot?

• Routing a single request through multiple nginx backend apps

  - by Jonathan Oliver

  I wanted to get an idea if anything like the following scenario was possible: Nginx handles a request and routes it to some kind of authentication application where cookies and/or other kinds of security identifiers are interpreted and verified. The app perhaps makes a few additions to the request (appending authenticated headers). Failing authentication returns an HTTP 401. Nginx then takes the request and routes it through an authorization application which determines, based upon identity and the HTTP verb (put, delete, get, etc.) and URL in question, whether the actor/agent/user has permission to performed the intended action. Perhaps the authorization application modifies the request somewhat by appending another header, for example. Failing authorization returns 403. (Wash, rinse, repeat the proxy pattern for any number of services that want to participate in the request in some fashion.) Finally, Nginx routes the request into the actual application code where the request is inspected and the requested operations are executed according to the URL in question and where the identity of the user can be captured and understood by the application by looking at the altered HTTP request. Ideally, Nginx could do this natively or with a plugin. Any ideas? The alternative that I've considered is having Nginx hand off the initial request to the authentication application and then have this application proxy the request back through to Nginx (whether on the same box or another box). I know there are a number of applications frameworks (Django, RoR, etc.) that can do a lot of this stuff "in process", but I was trying to make things a little more generic and self contained where different applications could "hook" the HTTP pipeline of Nginx and then participate in, short circuit, and even modify the request accordingly. If Nginx can't do this, is anyone aware of other web servers that will perform in the manner described above?

• Why can't I specify the executable that opens file with extension on windows?

  - by Glen S. Dalton

  I am on windows server 2003, but I guess it is the same on windows xp. This is a superuser question, because it is definitly desktop, so do not move or close it. Question: I copied some movable applications (usually people create them for usb sticks) to locations like c:\bin\app1\app1.exe app1.exe can open files of type *.ap1 When I rightclick file.ap1 and choose "open with ..." the "Open with" dialog appears. But it is not working how I expect in this situation. I can choose c:\bin\app1\app1.exe with the "Browse" button, but: app1.exe will not appear in the dialog where I just choosed it in the programs list, like I am used to it after clicking OK on it in the browse dialog. app1.exe will not open it when I click ok in the "Open with" dialog, the application that was assigned until then will still open it What could be the reason? Edit: Additional Information: my account is member of the administrators group I just changed the permissions of the folder c:\bin\app1\ and made sure that the group "Administrators" has all rights. I also inherited this manually to all subfodlers and subfiles.

• SQL Server 2005 standard filegroups / files for performance on SAN

  - by Blootac

  Ok so I've just been on a SQL Server course and we discussed the usage scenarios of multiple filegroups and files when in use over local RAID and local disks but we didn't touch SAN scenarios so my question is as follows; I currently have a 250 gig database running on SQL Server 2005 where some tables have a huge number of writes and others are fairly static. The database and all objects reside in a single file group with a single data file. The log file is also on the same volume. My interpretation is that separate data files should be used across different disks to lessen disk contention and that file groups should be used for partitioning of data. However, with a SAN you obviously don't really have the same issue of disk contention that you do with a small RAID setup (or at least we don't at the moment), and standard edition doesn't support partitioning. So in order to improve parallelism what should I do? My understanding of various Microsoft publications is that if I increase the number of data files, separate threads can act across each file separately. Which leads me to the question how many files should I have. One per core? Should I be putting tables and indexes with high levels of activity in separate file groups, each with the same number of data files as we have cores? Thank you

• Virtualbox - differencing disk based on different differencing disk

  - by Klinki

  I'm trying to create differencing image based on differencing image in VirtualBox 4.2.18. Official documentation says it should be possible: http://www.virtualbox.org/manual/ch05.html#diffimages Basically I want to achieve this drive hierarchy: + immutable image with Debian and all software installed +---- differencing image with specific configuration, autoreset=off, readonly +-------- differencing image with autoreset=on +---- another differencing image for different virtual machine +-------- differencing image with autoreset=on I successfully created differencing image based on differencing image, but I'm not able to connect it to virtual machine :( It always shows error: Failed to open the hard disk .... cannot register hard disk ... because hard disk with UUID ... already exists Here is screenshot of Virtual Media Manager and error dialog Virtual Media Manager Window screenshot Very strange is that the new differencing image (tempdrive.vdi) doesn't have Actual Size 0. I wasn't able to connect it, but still, it has 36KB of data on it... This is very similar to this older question: How to create a chained differencing disk of another differencing disk in Virtual Box? but suggested solution is not working anymore in VirtualBox 4.2.18, so I posted it as a new question. (Limit for posting links and screenshots is quite annoying..)

• What does a DHCP-client consider to be the "best" answer?

  - by Nils

  We have training rooms where normally Windows XP is installed (via PXE). The "normal" DNS/DHCP infrastructure are Windows-Servers. The training room has its own VLAN (different from the Windows servers), so there is most propably an IP helper for DHCP requests active on the Cisco router where all PCs from that room are connected to. Now we wanted to convert some of the PCs to Linux instead. The idea was: Put our own Laptop with a DHCP server into the VLAN of the room and override the "normal" DHCP response. The idea was that this should work, since a directly attached DHCP server in that VLAN should have a faster response-time than the "normal" DHCP server located some hops away from that VLAN. It turned out that this did not work. We had to manually release the lease on the original DHCP server to get it working. On the Laptop we did see the client requesting the IP and "our" dhcp was sending NACKs to the Windows IP request, before that we did offer our own response. Old Question: Why did this not work out as expected? What is making the PC regain its old lease? Update 2012-08-08: The regain-issue has been explained in the DHCP-RFC. Now this explains why the PC regains its old lease. Now we do release the IP from the Windows-DHCP-server before giving it another try. Again - the Windows-DHCP-server wins. I suspect that there is some algorithm for the dhcp-client which determines the "best" dhcp-answer for the client. The new question is: How does the client choose the "best" answer?

• Is this a File Header / Magic Number?

  - by Hammer Bro.

  I've got 120,000 files (way more, actually; this is just an arbitrary subset) of an unknown type. Linux file does not identify them (not that they're necessarily Linux files), nor do any other methods I've tried. There are only two hints about them that I currently have. One is that I suspect some compression is employed -- I have metadata that claims the file sizes are always some amount larger than what I observe. The other is that in 100,000 of these files, the first 16 bytes are always: ff ee ee dd 00 00 00 00 01 00 00 00 00 00 00 00 That really looks like a file header/magic number to me, but I just can't place it. Does anyone know what kind of files this would indicate? Alternatively, can anyone convince me that these suspiciously common bytes certainly do not indicate a specific file type? UPDATE I don't know the exact reverse-engineering details, but most of the files in our case are zips after the first 29(? or so) bytes are ignored. So in practice the problem is solved (we know how to process the files) but in theory the question is still unanswered -- I don't know which application routinely prepends about 29 bytes to its zips. [I'm not sure if I should leave the question open or not at this point.]

• Massive SQL issue shutting down our site.

  - by Pselus

  Our website has started timing out like crazy today. All of our clients are finding it unusable. The only error we can seem to trace down as a potential problem is this: SQLAllocHandle on SQL_HANDLE_DBC failed Error ASP Description Error Category Microsoft OLE DB Provider for ODBC Drivers I have no idea what it means or how to go about fixing it. Anyone ever encountered this error before? Currently, you can log in to our site, but then once you go to do anything else, you find yourself logged out or nothing happens. We have a lot of Ajax going on so the "nothing happens" probably has to do with the Ajax pages not loading properly due to logouts and so nothing displays to the user. Like I said, I'm at a loss. Anyone have any advice on this error? EDIT I realize that this isn't necessarily a programming question, but we are a small startup company that just yesterday started talking about how we need to get a backup server running. Apparently we talked about it too late. We don't have a DBA, just 2 mid level programmers trying their hardest to keep our clients happy. So please, if you have any assistance give it but please don't close my question right now. EDIT 2 Turns out we had something on our server running called "ServerMask" that makes our IIS server look like Apache to the outside world. Shutting it down fixed our issue. Still no idea why it was messing up but it was the problem apparently. Thanks to everyone who tried to help.

• Repository bugzilla package changed to bugzilla3 in Lenny; upgradable?

  - by Pukku

  This question was asked in debianhelp.org almost half a year ago, but never got an answer. I wasn't the one who posted it, however I was today facing exactly the same question. Not sure if copying it to here as such is considered as inappropriate or something, but there's not really anything that I would even like to paraphrase... So let's just go. (I'm sure you will be happy to close it, if this is not the way to go :) Hello all! We are using a Bugzilla server install on a Debian 4/Etch server and are starting to look at the upgrade to Debian 5/Lenny. I was hoping to upgrade the existing Bugzilla server and database from the oldstable (v2.22) to the newer stable in Lenny (v3) when we get to doing a dist-upgrade. However from testing in a virtual machine it seems that the old package was called "Bugzilla" whereas the Lenny package is called "Bugzilla3" and I could not figure a way to directly upgrade between the two. Is it possible to establish some kind of upgrade path quickly after the dist-upgrade to minimise downtime using apt-get or aptitude? Going on past experiences I would not want to do a fresh install with the Bugzilla3 package and attempt to inject the old database into it (previous attempts failed miserably!) :(

• Load Sharing Regarding Large Websites

  - by JHarley1

  Hello, I have a question regarding Load Sharing for large websites. My Understanding: So if you have a website that has millions of fits a day you will need to have an architecture that can support this sort of pressure. You can either do one or two things: Invest in a single large server that has huge amounts of processing power, memory and storage (such as Microsoft's TerraServer). Spread the load of your website across a number of machines. Let me tackle the second approach, so you have a collection of machines all running Web Server Software and all having access to identical copies of the websites pages. You can either spread the load across these machines using a cyclic pattern in a DNS or you can use a Load Ballancing Switch. The advantages of this approach is: - Redundancy - servers can fail and the others would "pick up the slack" - Incremental - the ability to easily add new machines to this set-up. My Question's Is there a Virtual approach to this issue of load balancing now? If the website runs from a database - is there still only a single copy of the database? If a user had a session running on one Server (e.g. they had gone to www.example.org and had been assigned to Server 2 - were they had created a session) if they refreshed the website (and were allocated Server 3) would they still have their session? What are the other disadvantages associated with Load Balancing? Many Thanks, J

• Fix MBR from installed Windows Vista

  - by Danilo

  Hi guys, I have a quite strange problem. I had a system with Vista and Ubuntu installed. We always use Vista and Ubuntu was something we really did not need. BUT: to boot, GRUB was used (I guess grub2). Now, while being in Vista I cancelled the Ubuntu partition and with it also GRUB. Now the system does not boot anymore. I tried to reinstall Ubuntu, but I had some problems with the CD. At the moment, when the system boots I get into the GRUB shell. From there, I am able to boot Windows Vista with some commands like this ones: grub> title windows rootnoverify (hd0,msdos3) chainloader +1 boot Now the question is: if I am able to boot in Windows Vista with this trick, is it possible to fix the MBR from inside the installed windows Vista with some command/tool of Vista itself? I shall probably mention that we are not interested in double boot at the moment. We only want Vista to start. I can sum up the question like this: is there a way to fix the MBR from the installed version on Windows Vista, considering that GRUB is at the moment installed? I hope I was clear enough. Thanks for your help.

• SQL 2K5 - Multiple databases vs. Multiple files

  - by Bob Palmer

  Hey all, quick question. Our current legacy system was built using multiple distinct databases (about ten of them). These are all part of the same discreet system, and a large number of SPs and functionalty span multiple databases. There are also key relationships that span (for example, a header table may be in database A with history, etc. in database B). When deploying multiple copies of our app to the same server therefore, we have to use multiple instances (because the database names are coded into so many sprocs). We're evaluating the idea of taking these ten databases (about 30gb total with individual sizes ranging from 100mb to 10gb) and merging them into a single database. Currently, we have our databases spread accross multiple spindles for better IO. The question I have is whether or not there is any performance loss or benefit of having 10 different databases vs. 10 different database files? i.e. rather than having three databases (A, B, and C) Disk D: A.mdf (1gb) Disk E: B.mdf (4gb) Disk F: C.mdf (10gb) Disk G: A_Log.ldf, B_Log.ldf, C_Log.ldf have one database (X) Disk D: X1.mdf (5gb) Disk E: X2.mdf (5gb) Disk F: X3.mdf (5gb) Disk G: X1_log.ldf,X2_log.ldf,X3_log.ldf Thanks! -Bob

• apache 2.4, mod_proxy_fcgi not honouring .htaccess, work around needed

  - by user229874

  I am using apache 2.4.7 with mod_proxy_fcgi for purpose of passing through php to php-fpm (this will be used for shared hosting environment). The htaccess works fine for non php files, but once it hit rewrite rule that proxies through the php requests, the htaccess is ignored. I know why it is happening. The question is: how do I work around it? The question how do I force apache to treat the request to php file as a request to local file, and then proxy it through? I have spent substantial time in researching on this problem, and following "answers" were given as solution: 1) "use apache configuration instead of .htaccess" it is valid solution, but not for shared hosting environment (I am not going to give access to apache configuration to shared hosting customers ;)). 2) "don't use .htaccess, as it has performance/security/other issues", well how else would shared hosting customers control access/url rewriting on their site? Besides if the .htaccess was not a requirement I would simply use nginx. 3) "put rewrite rule for proxy inside of " - this is incorrect, and it does not work. This behaviour appears to be not a bug but a "feature" as per https://issues.apache.org/bugzilla/show_bug.cgi?id=54887

• Who owns the IP rights of the software without written employment contract? Employer or employee? [closed]

  - by P T

  I am a software engineer who got an idea, and developed alone an integrated ERP software solution over the past 2 years. I got the idea and coded much of the software in my personal time, utilizing my own resources, but also as intern/employee at small wholesale retailer (company A). I had a verbal agreement with the company that I could keep the IP rights to the code and the company would have the "shop rights" to use "a copy" of the software without restrictions. Part of this agreement was that I was heavily underpaid to keep the rights. Recently things started to take a down turn in the company A as the company grew fairly large and new head management was formed, also new partners were brought in. The original owners distanced themselves from the business, and the new "greedy" group indicated that they want to claim the IP rights to my software, offering me a contract that would split the IP ownership into 50% co-ownership, completely disregarding the initial verbal agreements. As of now there was no single written job description and agreement/contract/policy that I signed with the company A, I signed only I-9 and W-4 forms. I now have an opportunity to leave the company A and form a new business with 2 partners (Company B), obviously using the software as the primary tool. There would be no direct conflict of interest as the company A sells wholesale goods. My core question is: "Who owns the code without contract? Me or the company A? (in FL, US)" Detailed questions: I am familiar with the "shop rights", I don't have any problem leaving a copy of the code in the company for them to use/enhance to run their wholesale business. What worries me, Can the company A make any legal claims to the software/code/IP and potential derived profits/interests after I leave and form a company B? Can applying for a copyright of the code at http://www.copyright.gov in my name prevent any legal disputes in the future? Can I use it as evidence for legal defense? Could adding a note specifying the company A as exclusive license holder clarify the arrangements? If I leave and the company A sues me, what evidence would they use against me? On what basis would the sue since their business is in completely different industry than software (wholesale goods). Every single source file was created/stored on my personal computer with proper documentation including a copyright notice with my credentials (name/email/addres/phone). It's also worth noting that I develop significant part of the software prior to my involvement with the company A as student. If I am forced to sign a contract and the company A doesn't honor the verbal agreement, making claims towards the ownership, what can I do settle the matter legally? I like to avoid legal process altogether as my budget for court battles is extremely limited at the moment. Would altering the code beyond recognition and using it for the company B prevent the company A make any copyright claims? My common sense tells me that what I developed is by default mine in terms of IP, unless there is a signed legal agreement stating otherwise. But looking online it may be completely backwards, this really worries me. I understand that this is not legal advice, and I know to get the ultimate answer I need to hire a lawyer. I am only hoping to get some valuable input/experience/advice/opinion from those who were in similar situation or are familiar with the topic. Thank you, PT

• Limiting access in Silverlight\Pivotviewer

  - by sparaflAsh

  I'm going to deploy a pivotviewer application. As some of you might know this silverlight application load a .cxml index file for a group of images. My need is to make .cxml file and image files not accessible for the user. Now, if I don't have a need I usually code like this in C# and the file is hosted in the documentroot: _cxml = new CxmlCollectionSource(new Uri("http://www.myurl.it/Collection.cxml", UriKind.Absolute)); This means that my cxml and then the images are available by http for everyone who knows the URI. I'm a newbie to server configuration, so any help/hint would be deeply appreciated. Someone suggested me to take the files out of the root, but it seems like I can't go to pick them up if they are not a URL in Silverlight. At least I didn't managed to understand how. Someone else suggested me to play with web.config file to hide URLs, but I don't really know where to start. My question is, what's the best practice to hide my stuff? Obviously I can edit the question if you need more details.

• How to setup Mac server to use two gateways

  - by Brady

  I recently asked this question: How to set Mac server to use different Gateway for internet bound traffic The answer given works but has presented me with another issue that I didnt make clear in that question. Here is my network layout as it stands: At the moment outside staff members use some services on the existing internet 1 link. Those services are hosted by the Mac server. If I change the gateway of the Mac server to the second modem those outside staff lose visabilty on those services. Now I dont know how to go about solving this issue. I want the second link to be used when the Mac server goes to rsync data offsite but everything else use link one. How do I do this? Thanks Scott EDIT: This has been resolved by setting the default gateway on the Mac server to 192.168.1.254 Thus leaving everything on the network as it was before. but to get the Mac server to use the other link for rsync I've added a route to the Mac server to route traffic to the rsync server through the second gateway. sudo route add -net {server IP's}/{Netmask} 192.168.1.1 I've awarded the answer to gravyface for pointing me to a post on how to make this route persistant in Mac

• Ubuntu server or Debian server (to run C++ apps developed on Ubuntu)

  - by skyeagle

  I have written a number of C++ server side daemons for my website, using my Ubuntu 9.10 dev machine. The C++ apps I mentioned above are "GUI-less" daemons (and libraries used by the daemons). I am now about to host my website and need to decide whether to go with Debian server or Ubuntu server. In a nutshell, here is the situation: I developed on Ubuntu desktop because I preferred the more friendly GUI I would like to deploy on Debian Server because of the (perceived?) robustness of the Debian server over Ubuntu server (I may be totally wrong here - and in fact, this is really what this question is all about) If Debian server is indeed more robust than Ubuntu server, then I have no choice but to go with Debian server - BUT, will my Ubuntu developed C++ apps run on the server? (or do I need to recompile them on the server? (I'd HATE to have to do this, because I want to keep the server machine clean and light - no GUI, no dev tools etc). This last question is really about binary compatability between Ubuntu and Debian. I want the server to be robust, secure and stable, and simply act as a server (i.e. LAMP and very little else - no GUI etc). Given that requirement, and the fact that I need to run my C++ apps (developed on Ubuntu 9.10), I need advice on which OS to choose for the server. Ideally, any advice will be backed with a reason. I am particularly interested in hearing from people who have been in an identical situation, or done something similar.

• AMD 700, 800 series chipset. I'm lost.

  - by Shiki

  I've been an Intel / NVidia user ever since I started using computers. Intel really gone up with the prices, and they won't get cheaper. So I decided to get an AMD. But WHICH one? I mean.. not shopping question but.. what are the differences? Like: 880GMA comes only with a single PCI ex and it looks like a chinese replica (no offense). While 890FX comes with 5PCI-ex for QuadCrossfire. Also.. what's the deal with 7xx series? I mean.. its the same price. Yet its older? Or why is it 7xx? Isn't there a single chipset between? Not chinese YET it's durable/fine for long-term usage? What it should know (desktop stuff): NVidia GPU (Zalman AMP2 GTX 260^2 (one card)) Phenom 1090T cpu A somewhat good audio. Any ideas which is the chipset I'm searching for? If this sounds too much of a shopping question, feel free to edit. I just want some clarification on these chipsets.

• Ubuntu Device-mapper seems to be invincible!

  - by Andrew Bolster

  I'm working on a hopefully unrelated question question and I've got to a strange situation. First: I know very little about the very low level hardware kernal storage driver magix, so I'm hoping a) someone can help and b) someone can explain it to me better. I've been trying a dozen different configurations of my 2x500GB SATA drives over the past few hours involving switching between ACHI/IDE/RAID in my bios; After each attempt I've reset the bios option, booted into a live CD, deleting partitions and rewriting partition tables left on the drives. Now, however, I've been sitting with a /dev/mapper/nvidia_XXXXXXX1 that seems to be impossible to kill! its the only 'partition' that i see in the Ubuntu install (but I can see the others in parted) but it is only the size of one of the drives, and I know I did not set any RAID levels other than RAID0. Anyone have any ideas how I can kill this and get back to just two independent IDE drives? Or can anyone convince me of a reason to go the AHCI route? Many thanks in advance.
