  • Hardware for multipurpose home server

    - by Michael Dmitry Azarkevich
    Hi guys, I'm looking to set up a multipurpose home server and hoped you could help me with the hardware selection. First of all, the services it will provide: Hosting a MySQL database (for training and testing purposes) FTP server Personal Mail Server Home media server So with this in mind I've done some research, and found some viable solutions: A standard PC with the appropriate software (Either second hand or new) A non-solid state mini-ITX system A solid state, fanless mini-ITX system I've also noted the pros and cons of each system: A standard second hand PC with old hardware would be the cheapest option. It could also have lacking processing power, not enough RAM and generally faulty hardware. Also, huge power consumption heat generation and noise levels. A standard new PC would have top-notch hardware and will stay that way for quite some time, so it's a good investment. But again, the main problem is power consumption, heat generation and noise levels. A non-solid state mini-ITX system would have the advantages of lower power consumption, lower cost (as far as I can see) and long lasting hardware. But it will generate noise and heat which will be even worse because of the size. A solid state, fanless mini-ITX system would have all the advantages of a non-solid state mini-ITX but with minimal noise and heat. The main disadvantage is the read\write problems of flash memory. All in all I'm leaning towards a non-solid state mini-ITX because of the read\write issues of flash memory. So, after this overview of what I do know, my questions are: Are all these services even providable from a single server? To my best understanding they are, but then again, I might be wrong. Is any of these solutions viable? If yes, which one is the best for my purposes? If not, what would you suggest? Also, on a more software oriented note: OS wise, I'm planning to run Linux. I'm currently thinking of four options I've been recommended: CentOS, Gentoo, DSL (Damn Small Linux) and LFS (Linux From Scratch). Any thoughts on this? Any other distro you would recomend? Regarding FTP services, I've herd good things about FileZila. Anyone has any experience with that? Do you recommend it? Do you recommend something else? Regarding the Mail service, I know nothing about this except that it exists. Any software you recommend for this task? Home media, same as mail service. Any recommended software? Thank you very much.

  • Small font all 'new' messages suddenly in Gmail on Ubuntu in Opera, why?

    - by Michael Durrant
    This seemed to happen out of the blue. I have been using Opera for years. I can't find anywhere in Gmail to change the default font that is used in Opera. Ubuntu is Version 11 Opera is version 11.6 In Firefox the font is normal size. I have tried playing around with both all the browser setting I can find plus Ubuntu system settings (I had seen some mentions of Opera using the system default font sometimes) but no success so far. Really bumming as I have been using Opera for two years and if I can't resolve it I will not be able to use it. I can switch to Firefox but I don't want to.

  • SQL Server database constantly restarting

    - by Michael Itzoe
    We have SQL Server 2008 Express installed on a Windows 2003 server. Looking at the event log, one of the databases appears to be restarting anywhere from every couple seconds to every 15 to 30 minutes. This server hosts about half a dozen databases; the problem is with only one. This database is also the onle one comprised of multiple schemas (not just dbo). There are thousands of events going back several months. There doesn't seem to be any affect on the website using the database, nor does any data appear to be corrupted or compromised. I'm not a DBA, so I don't even know where to look for causes to this. Any suggestions?

  • What makes an Apple hard drive special?

    - by Michael Shnitzer
    The Mac Pro has a specific hard drive for sale in the Apple Store for $549.00. The drive has the following specs: Serial ATA 3GB per second 7200 RPM Amazon has a hard drive with the same specs for $169.99. The only difference I can tell is that the Apple hard drive label says it has "Apple HDD Firmware". What exactly is the benefit of this firmware and is there something I am missing that make up for the price difference in these two drives? Update: My initial comparison between the two drive was unfair. Apparently 2TB drives that are 3 GB/S and 7200 RPM are quiet a bit more than $169.99. Dell has a 2 TB SATA Caviar Black from Western Digital that is $319.99, which is closer to Apple's price.

  • Using screen to monitor non-interactive scripts (or some other solution)

    - by Michael
    I have some autonomous scripts that run commands on remote machines over ssh. These scripts rely on getting stdout, stderr, and the return code of each command run. I want to be able to monitor the progress of the scripts on each target machine so that I can see if something has hung and possibly intervene if necessary. My initial idea was to have the scripts run commands in a screen session, so that the person monitoring could simply attach to the session with screen -x. However, it was hard to do that from a script since screen is an interactive program. I can send a command to the screen session with screen -S session -X stuff "command^M", but then I don't get the output and return code that I need back. My second idea was to put script /path/to/log in ~/.bash_profile and log the entire session to a file. Then the monitoring person could simply tail the log file. However, this doesn't provide the interactivity that I was looking for. Any ideas on how to solve this problem?

  • CentOS server. What does it mean when the total used RAM does not equal the sum of RES?

    - by Michael Green
    I'm having a problem with a virtual hosted server running CentOS. In the past month a process (java based) that had been running fine started having problems getting memory when the JVM was started. One strange thing I've noticed is that when I start the process, the PID says it is using 470mb of RAM while the 'used' memory immediately drops by over a 1GB. If I run 'top', the total RES used across all processes falls short of the 'used' listed at the top by almost 700mb. The support person says this means I have a memory leak with my process. I don't know what to believe because I would expect a memory leak to simply waste the memory the process is allocated not to consume additional memory that doesn't show up using 'top'. I'm a developer and not a server guy so I'm appealing to the experts. To me, if the total RES memory doesn't add up to the total 'used' it indicates that something is wrong with my virtual server set-up. Would you also suspect a memory leaking java process in this case? If I use free before: total used free shared buffers cached Mem: 2097152 149264 1947888 0 0 0 -/+ buffers/cache: 149264 1947888 Swap: 0 0 0 free after: total used free shared buffers cached Mem: 2097152 1094116 1003036 0 0 0 -/+ buffers/cache: 1094116 1003036 Swap: 0 0 0 So it looks as though the process is using (or causing to be used) nearly 1GB of RAM. Since the process (based on top is only using 452mb, does that mean that the kernal is all of a sudden using an additional 500mb?

  • Moving SQL Server databases from one drive to another?

    - by Michael Stum
    I have a SQL Server 2008 R2 on my machine which stores everything on the C: drive (C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA). I got an additional Hard Drive now and would like to move all the databases over. It's 26 databases, so I'd like to avoid manually disconnecting/reconnecting them. Ideally I would just like to move them from C: and D: and tell SQL Server to look there. Downtime is not an issue, I just don't want to do dozens of mouse clicks :)

  • How to avoid trailing spaces when you copy something from terminal?

    - by Michael Härtl
    I often copy a code snippet from a SSH terminal session where i'm logged in to some remote server and have a file opened in vim, for example to paste it here into an answer at SO. It frequently happens, that the code is padded with trailing spaces to match the terminal width. Whereas i've seen this on both, my Ubuntu and Windows machines (using putty) i think, it doesn't happen always. I was not able to figure out when it happens, though. So i wonder how i can avoid those trailing spaces which i have to remove manually all the time in the textarea, where i copy it to. Note, that the files do not have trailing spaces on the server! It only happens if i select and copy some text.

  • IIS 7: One Page Works, All Others Fail With "Error code: ssl_error_rx_record_too_long"

    - by Michael
    On my local machine, I have a second site bound to Port 81. Within that site is a certain page which I can browse from other machines with no problems, but all other pages fail with "Error code: ssl_error_rx_record_too_long". Each of the failing pages (as well as the lone working page), works with localhost. So, from any machine, local or remote: http://cmwmach01.mydomain.biz:81/RD/SS/SS.aspx (works) http://cmwmach01:81/RD/SS/SS.aspx (works) http://cmwmach01.mydomain.biz:81/RD/POV/SC.aspx (fails - gets changed to https) http://cmwmach01:81/RD/POV/SC.aspx (fails - gets changed to https) Everything works with localhost (locally, of course). I've tagged this question with SSL because, at one point, it would warn about an SSL cert issue (maybe this was self-signed at one point?), but now it doesn't. While there may be an issue around that, I don't see how this could cause the issue I am seeing (but, as I mention below, am I way out of my depth here). I am way out of depth here in trying to figure out why that one page works (or the others don't), so that I can make them all work. Any ideas?

  • How do I open files from the command line in Mac

    - by Michael
    I'm following a video tutorial where the author (who uses textmate) can open files by using "mate". for example mate .git/config will open this config file I'm using textwrangler however so I don't have that option. I did try edit .README once when i tried to open the README file of an application, but it opened a blank README file in textwrangler instead of the file with the text in it so any idea how I can open this .git/config file (or any other file) using textwrangler? I'm using Mac snow leopard

  • Firefox extension to translate selection boxes

    - by Michael
    Many extensions can translate selected texts. What if the text located within selection box? Meanwhile I can't translate the whole website because google translator says "Sorry, we are unable to translate the page you requested." I can use firebug to explore html, copy the text to google translator and do translation. Wondering if there is such add-on for firefox to translate text from "non selectable" HTML elements. Thx

  • Any software to remove $NtUninstallxxxxx

    - by Michael
    Any commercial or free software to give me a list and descriptions of patch uninstalls and let me remove selected ones? I've tried Windows XP Update Remover, but seems it doesn't provide any information for majority of items and I have to delete one by one... I also know I can do it manually, but just wondering if there is more professional software to make it more accurate and quick.

  • Any reasonable UPS for a Desktop PC, just to shut it down?

    - by Michael Stum
    While I do have a surge protector to protect against overvoltage (hopefully), I have nothing against undervoltage. When a lightning storm hits, I had the lights flickering at some point. The PC continued to run, but it got me thinking of getting a UPS as a way to a) have a clean 120V/60Hz power source and b) have a way to shut down the PC in case something bad happens. I heard not all UPS' protect against power spikes, so I wonder if someone has a recommendation? It does not need to keep the PC on for a long time if the power goes out, it's good enough if it shuts down the PC after 5 minutes or so. There are 2 PCs connected. One is a Core i7-860 with a Radeon 5870 running Windows 7 Ultimate (so quite power hungry. It uses a 600W PSU but I have no measurements of the actual usage), the other one is a Windoes Home Server, running WHS/Windows Server 2003. Any recommendations in the low-price segment?

  • Exchange 2010 SP1 upgrade prerequisite checks fail for KB979744, but update fails as Not Applicable

    - by Michael Shimmins
    I'm trying to install the SP1 update to an RTM Exchange 2010 box. The Client Access Role Prerequisites are failing, complaining that KB979744 isn't installed. I downloaded the update and tried to install it, however it will not install complaining that 'The update does not apply to your system'. A discussion on TechNet indicates that I need .NET 2.0 or 3.5 installed (both are). Aside from that I've been unable to find anything helpful. Hopefully someone has encountered this and knows how to get around it, don't really want to use up a support call on this. Edit: This is on a 64-bit edition of Windows Server 2008 Datacenter (without Hyper-V) SP2.

  • How to avoid Remove-Item PowerShell errors "process cannot access the file"?

    - by Michael Freidgeim
    We are using TfsDeployer and PowerShell script to remove the folders ising Remove-Item before deployment of a new version. Sometimes the PS script failed with the error Remove-Item : Cannot remove item Services\bin: The process cannot access the file Services\bin' because it is being used by another proc Get-ChildItem -Path $Destination -Recurse | Remove-Item <<<< -force -recurse + CategoryInfo : WriteError: (C:\Program File..\Services\bin:DirectoryInfo) [Remove-Item], IOException FullyQualifiedErrorId : RemoveFileSystemItemIOError,Microsoft.PowerShell.Commands.RemoveItemCommand I’ve tried to follow the answer from PowerShell remove force to pipe get-childitem -recurse into remove-item. get-childitem * -include *.csv -recurse | remove-item ,but the error still happens periodically. We are using unlocker to manually kill locking application, (it’s usually w3wp), but I prefer to find automated solution. Another (not ideal) option is to-suppress-powershell-errors get-childitem -recurse -force -erroraction silentlycontinue Any suggestions are welcome.

  • How to get linux to stop asking "There are # rows, list them anyway? [n/y]" for auto-completing

    - by Michael
    How do I get tcsh to stop asking if I want to list files in a directory that may have a lot of auto-completes? For example, if I do: xemacs ../"TAB" to get the list of files it asks: There are 371 rows, list them anyway? [n/y] I don't want it to ask this, just list them.. it's getting tiresome. (Or how to at least set the tolerance to a higher number of auto-completes before it asks) Thanks.

  • How to launch Google Chrome Application Shortcuts in Linux?

    - by Michael Rose
    I've got Chrome running on my Linux netbook, it's great and, unlike the Mac version, the 'Create Application Shortcut' option isn't greyed out. So I created one for Gmail. The 'applications' get stored at ~/.local/share/applications but I haven't managed to launch it yet. If I use Chrome in terminal $ google-chrome ~/.local/share/applications/google-application-reallylong-randomname.thing It opens the file in a new tab in Chrome and helpfully downloads it for me! Anyone got application shortcuts working in Linux?
