  • What is the difference between Startup programs in windows and the same programs being started manually

    - by sup
    I am no Windows guy, but I am trying to get a seamless integration of Windows program through Virtual Box Windows guest onto my Ubuntu machine. I more or less followed this tutorial: https://nowhere.dk/articles/running-windows-applications-natively-with-seamlessrdp Basically I start up Windows in Virtual Box and then I try to launch an application (on Ubuntu host) like this: rdesktop -A -s "c:\Program Files\ThinLinc\WTSTools\seamlessrdpshell.exe notepad.exe" 192.168.123.103:3389 -u user -p password That just gives me full Windows desktop that I do not want. However, when I run (on the Windows guest) "c:\Program Files\ThinLinc\WTSTools\seamlessrdpshell.exe" "notepad" The command above works and I get just the window I want. Now, so I thought I would put this command into startup folder of the Windows machine and everything would be fine. But it says "Unable to set up the virtual channel". (by googling, I nailed it to this file: https://sourceforge.net/p/rdesktop/code/1686/tree/seamlessrdp/trunk/ServerExe/vchannel.c - the warning is triggered (by main.c in the same directory) when function vchannel_open() returns something that C interprets as yes for if condition). I have no idea why it works when I launch this command manually via a bat file and not when I put it to startup programs. Any ideas?

  • How to make Exchange 2003 non-authoritive

    - by Romski
    Background We are a small company with an internally hosted Exchange 2003. It receives email for 2 domains (the company was renamed a few years back). For the sake of argument, the domains are: oldname.com newname.com We have moved newname.com to a hosted exchange service, and our DNS record is correctly routing emails. Our internal server still receives email for oldname.com, although we have asked our hosting company to accept emails for that domain. Problem My problem is that emails generated internally from monitoring software, printer, etc. are being caught by our (defunct) internal server and being delivered to the old mailboxes. I believe that what is happening is that our internal exchange server considers itself to be the authoritive server for newname.com. I think it must be looking in active directory for a mailbox and delivering it internally without ever going outside. Attempt to fix I started to follow the article here: http://support.microsoft.com/kb/321721. I removed the SMTP recipient policy for newname.com, and added a dummy address and made it primary. I also answered yes for updating the associated emails. I then restarted the Microsoft Exchange Routing System and SMTP, but emails are still being routed internally. Is there a way to force the exchange server to route all emails for the domain newname.com to the new hosted service?

  • Mapped networkdrive on logout

    - by Robuust
    I'm using a script to keep a mapped networkconnection alive, but ofcourse the mapped connection is gone when I logout. The point is now, that I'm running this on Windows Server 2008 R2, where I use remote desktop to login on the administrator account. However, it should remain logged in and not remove the mapped connection as this script takes care of not logging out on MS office 365 sharepoint. Is there a way to keep the mapped networklocation (L:) available after logout? So the script can run to remain the connection? # Create an IE Object and navigate to my SharePoint Site $ie = New-Object -ComObject InternetExplorer.Application $ie.navigate('https://xxx.sharepoint.com/') # Don't need the object anymore, so let's close it to free up some memory $ie.Quit() # Just in case there was a problem with the web client service # I am going to stop and start it, you could potentially remove this # part if you want. I like it just because it takes out a step of # troubleshooting if I'm having problems. Stop-Service WebClient Start-Service WebClient # We are going to set the $Drive variable here, this is just # going to tell the command what drive letter to map you can # change this to whatever you want (if you change it to a # drive that is already mapped it will overwrite it, so be careful. $Drive = "L:" # You can change the drive destiniation to whatever you want, # it has to be a document library or folder of course. $DrvDest = "https://xxx.sharepoint.com/files/" # Here is where we create the object to map the network drive and # then map the network drive $net = New-Object -ComObject WScript.Network; $net.mapnetworkdrive($Drive,$DrvDest) # That is the end of the script, now schedule this with task # scheduler and every so often and you should be set.

  • How much does a computer actually cost?

    - by Cawas
    Ok, so when you buy a new notebook, you spend about $1 or $2 thousand with the OS included. When you make your own desktop machine you can get as low as $100 for a good one today, with not a single piece of software included. It can't be much lower, but it can go lot higher. People, including myself, tend to believe that's the price of a computer, but then there comes the softwares. I just stumbled upon a nice piece of application I could use myself, but it's very specific, very tiny, and most people would never bother about this. And it costs "just $12". That is a lot for something I may use just once or twice! OS upgrades, hardware malfunction, and your custom set of software actually raise the computer price quite a lot, thus this question: how much we pay in the end for our personal computers? I'd like to see some statistics on that. Maybe divided into 3 categories or something, but some data with averages, minimum and "maximum" costs would be very nice. Maybe a "cost per year" would be nice. Just wondering.

  • Using ZFS or XFS on a Xen guest running Linux

    - by zoot
    Background: I'm investigating the viability of using a filesystem other than ext3/4, with the ability to run snapshots for backup and rollback purposes. The servers under consideration are mailbox server nodes running on Linode's Xen based VPS platform. I'm particularly drawn to the various published benefits which ZFS offers in terms of data integrity and this year's stable release of native ZFS support in Linux - http://zfsonlinux.org ZFS appears to be the more thorough option in terms of benefits and simplicity (instead of LVM+XFS). Please note that I have little experience with ZFS (which I use on a local FreeNAS installation) and none with XFS, hence the post. To date, my servers are using ext3 filesystems, not managed under LVM. Question in detail: So, I have two questions. (1) Which of the two filesystems would be the better choice for the best of all of the following 3 aspects, running on a Xen Linux guest? Snapshots Data Integrity Performance (2) If ZFS is a viable option, is it practical to use ZRAID across Xen disk images to further enhance the solution for data integrity? Note: I'm reluctant to consider btrfs, given the many warnings I've read about in using it on production systems.

  • How do I get the F1-F12 keys to switch screens in gnu screen in cygwin when connecting via SSH?

    - by Mikey
    I'm connecting to a desktop running cygwin via SSH from the terminal app in Mac OS X. I have already started screen on the cygwin side and can connect to it over the SSH session. Furthermore, I have the following in the .screenrc file: bindkey -k k1 select 1 # F1 = screen 1 bindkey -k k2 select 2 # F2 = screen 2 bindkey -k k3 select 3 # F3 = screen 3 bindkey -k k4 select 4 # F4 = screen 4 bindkey -k k5 select 5 # F5 = screen 5 bindkey -k k6 select 6 # F6 = screen 6 bindkey -k k7 select 7 # F7 = screen 7 bindkey -k k8 select 8 # F8 = screen 8 bindkey -k k9 select 9 # F9 = screen 9 bindkey -k F1 prev # F11 = prev bindkey -k F2 next # F12 = next However, when I start multiple windows in screen and attempt to switch between them via the function keys, all I get is a beep. I have tried various settings for $TERM (e.g. ansi, cygwin, xterm-color, vt100) and they don't really seem to affect anything. I have verified that the terminal app is in fact sending the escape sequence for the function key that I'm expecting and that my bash shell (running inside screen) is receiving it. For example, for F1, it sends the following (hexdump is a perl script I wrote that takes STDIN in binmode and outputs it as a hexadecimal/ascii dump): % hexdump [press F1 and then hit ^D to terminate input] 00000000: 1b4f50 .OP If things were working correctly, I don't think bash should receive the escape sequence because screen should have caught it and turned it into a command. How do I get the function keys to work?

  • ASUS M51SE freezes for no apparent reason

    - by Piotr Justyna
    First of all, it's my first question on superuser so please excuse me if it doesn't belong here, a similar one has already been posted here or if I missed some details. My ASUS M51 freezes up. It all started a couple of months ago and I basically forgot about it since I bought a new laptop around that time. This is, however, bugging me since then and I can't explain why it's happening. Let me quickly describe what's wrong. When switched on and running (win 7) it freezes after a couple of minutes of normal usage (or even if I don't actually do anything). By 'freezes', I mean it's like a static image of my desktop was being displayed on the screen. Nothing happens, alt+ctrl+del doesn't help, I basically have to switch it off using a power button. I tried to remove the hard drive and to start the laptop without it. The same here - it freezes on the the initial black loading screen (a couple of minutes after the computer says it can't find the hdd) I tried to remove RAM - the same thing. All fans are spinning as they should. I cleaned the fans using a small paintbrush but it doesn't change anything. The laptop is generally clean and in pretty good physical shape. Well, almost, obviously :). One possible clue I can think of is that the laptop is heating excessively even when it doesn't actually do anything (hdd removed). Do you have any ideas what is the cause of this or what else can I try? Thanks, Piotr

  • Proper Network Infastructure Setup DMZ, VPN, Routing Hardware Question

    - by NickToyota
    Greetings Server Fault Universe, So here's a quick background. Two weeks ago I started a new position as the systems administrator for an expanding health services company of just over 100 persons. The individual I was replacing left the company with little to no notice. Basically, I have inherited a network of one main HQ (where I am situated) which has existed for over 10 years, with five smaller offices (less than 20 persons). I am trying to make sense of the current setup. The network at the HQ includes: Linksys RV082 Router providing internet access for employees and site to site VPN connecting the smaller offices (using an RV042 each). We have both cable and dsl lines connected to balance traffic (however this does not work at all and is not my main concern right now). Cisco Ironport appliance. This is the main gateway for our incoming and outgoing emails. This also has an external IP and internal IP. Lotus domino in and out email servers connected to the mentioned Cisco gateway. These also have an external IP and internal IP. Two windows 2003 and 2008 boxes running as domain controllers with DNS of course. These also have both an external IP and internal IP. Website and web mail servers also on both external and internal IPs. I am still confused as why there are so many servers connected directly to the internet. I am seriously looking to redesign this setup with proper security practices in mind (my highest concern) and am in need of a proper firewall setup for the external/internal servers along with a VPN solution about 50 employees. Budget is not a concern as I have been given some flexibility to purchase necessary solutions. I have been told Cisco ASA appliance may help. Does anyone out in the Server Fault Universe have some recommendations? Thank you all in advance.

  • Windows XP dual screen problems, user account related

    - by Chris
    I have had this issue with a few laptops now and it looks like it is some sort of user account problem. Specifics of the system are: Dell Laptop Windows XP Pro SP3 Non-domain member computer DLP Projector connected to laptop via VGA I use this setup almost daily to do presentations, always the mirrored display mode where I can see on the laptop monitor the same thing that is displayed on the projector. Today, when I boot up, I get the mirrored display at the login screen, but after I log in, it switches to Extended Desktop (like two desktops side-by-side). Fn+F8 just cycles through all the normal settings except the mirrored display. I created a new user account on the computer and it performs normally. Mirrored display works as normal. I have run into this about 4 times now and it always can be solved by creating a new user account on the computer, and then all is well. I would like to either: 1. Find a way to reset the customized settings for a specific user account which would hopefully make this go away, or 2. Find the specific setting that causes this so that I can easily fix it when the problem comes up. Creating new user accounts is kind of a pain and a easy fix must be out there somewhere.

  • Ways to go about optimizing website performance WordPress, Amazon EC2 Apache and RDS MySQL

    - by fuzzybee
    I have 6 WordPress websites running on 1 single EC2 instance. All the the websites are connecting to databases in 1 same RDS instance. Earlier today, traffic to the largest website peaked and the RDS instance went bottle-neck - CPU utilization was 100% for over an hour. It affected all of my websites as it took them all forever to load. In order to prevent such issue from happening again, which of the following will matter most so that I invest time and effort in first of all? (I will work on all later, I just need to prioritise now) To improve caching for all websites To fine-tune the database server To fine-tune my Apache server What will be the effect on user experience for my websites? Some quick searches show that I should limit number of concurrent connections to my web server but wouldn't that prevent users from accessing my websites? More background: My largest website has 140k visits and 660k page views a month. The other 5 websites should add up much less than that. I'm using a large EC2 instance as the web server I'm using a medium RDS instance as the database server What I've already done: Use W3 Total Cache plugin for caching for most the websites, especially the largest one (I can barely anything else in terms of caching I could do for the largest website) Am I using my resources wastefully or is there simply not enough resources for my websites - or rather, how do I answer that question myself?

  • OS X Hard drive recovery

    - by Adam
    I am trying to recover data from a bad Seagate 1TB hard drive in a 2010 iMac. One day the iMac wouldn't boot (stuck at gray screen on startup). I removed the hard drive from the iMac and connected it to a MacBook using a 3.5" HDD to USB adapter. The hard drive wouldn't mount but it did display in Disk Utility that that there were 2 partitions on the disk. I tried to run Disk Warrior and it showed thousands of errors but still wouldn't mount. At this time the hard drive only show one partition in Disk Utility. Next I tried putting the hard drive in a desktop PC and running Spin Rite - which then gave me several division overflow errors (even with running Spin Rite with a newer version of DOS). The SMART status on the drive reports that the drive has had failures and HD Tune referenced the drive had once hit 59 degrees celsius. Disk Utility gives me the following message when running a pair: Error: Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files. Overall, the hard drive spins up and sounds OK - there are no clicking noises but the hard drive won't mount and displays as a light gray "Macintosh HD" in disk utility. Any tips or advice on how to recover data on this drive would be GREATLY appreciated! Are there any other tools I can try before calling it quits on this drive? Thank you

  • Utility to store/cache all web pages and YouTube videos

    - by jonathanconway
    I found myself in the following situation. I'm travelling abroad with my laptop. I connect to a WiFi point and do a bit of browsing and play a YouTube video or two. Then I disconnect and hop on either a plane or taxi. Now I want to go back to some of the webpages I was browsing before and continue reading them, or watch some more of that YouTube video. Unfortunately it seems like none of these resources are cached, or if they are, I have no idea how to access them. Here's what I'd like: A utility that starts when my computer boots and sits in the background, silently caching all the web pages that I view. Not only that, but also the resources such as YouTube videos. Later, when I re-navigate to a site while disconnected, the browser automatically pulls the pages from my cache rather than giving me a 404 error. Or I can click an icon in the system tray and see a list of all the pages/videos in the cache and view any that I like. I'm sure Internet Explorer had a feature like this at some point, like "Offline Mode" or something. But these days it doesn't seem to work. Even when I select that option I still can't view pages that I'm certain I downloaded before. So has the utility I'm talking about been developed yet?

  • Need help diagnosing my machine

    - by Tom Collins
    I have something that just slows my computer to a crawl sometimes. Not running anything big. Yesterday all I had running (besides background apps) were Firefox & Windows Explorer and could barely even switch screens. Nothing showing up in the task manager as hogging CPUs. I have all non-essential services stopped (MySQl & MSSQL) unless I need them. I made some restore points not long ago, but they disappeared. This is a development mach with a LOT of apps installed, so I really, really do not want to re-install Windows. So, what I'm looking for are ideas or tools I can use to help diagnose this problem. The only clues I have is this started right after I installed Office 2013 (with Office 2010 still installed as well) installed Visual Studio 2012 (also keeping 2010 as a co-install) and installed MSSQL 2012 (upgrade from 2008, no co-install) Also, computer runs fine in Safe Mode. I've just ran out of ideas of what to check. Any help / suggestions would much appreciated. Thanks P.S. I'm running Win 7 Pro (x64). Office is also 64 bit. Visual Studio & MSSQL are 64 bit if that option was available (not sure).

  • User Receiving Partial Downloads

    - by JGB146
    Some background: I run a subscription-based poker strategy video website. Our videos range in length from 30 mins up to 80 mins, and in size from 20MB up to 500MB. The site is on a shared server with hostmonster.com One of my users is having problems downloading some of the larger video file. He reports problems with anything over 100MB. Basically, he's only getting part of the file, which means that the video stops before the end. He has tried multiple computers from multiple locations. He reports that he is able to successfully download 500MB files from other sites. He is using Internet Explorer (version unknown) as his browser. I have suggested that he try Firefox or Chrome to see if their download managers work any better for him, but as of yet I have not heard anything back. He has also reported that his downloads do not report any filesize. I see the same thing (no file size reported), but I have not experienced any problems with the downloads themselves. We pass the downloads through a php script which verifies login information and records the download to our database before returning the file. I suspect this is why there is no filesize reported. What else should I ask the user? What other things could he or I try?

  • Why can't I see installed AIR applications in /Applications on Mac OS Lion?

    - by Damir Zekic
    Yesterday I did a clean install of Mac OS Lion, and installed bunch of apps, including HipChat Desktop Application (an Adobe AIR app). I used it for some time and eventually closed it. Today I wanted to start it again, but couldn't find it in Launchpad. I looked in /Applications folder, but I couldn't find it there either (I still don't have ~/Applications). I went back to HipChat website (from where I installed) and a Flash plugin allowed me to run the app immediately. It shows up in my Dock and if I "keep it" there, I can launch it again (it still doesn't appear in my /Applications dir). However, it asks me for confirmation about launching an app that has been downloaded from the Internet (every time I start it, it's annoying). I also see the app in Adobe AIR uninstaller. I then went to my old Snow Leopard installation and found HipChat in my /Applications folder there. Copied it to the Lion disk and it works. Now I have two HipChat entries in Adobe AIR uninstaller. I guess I solved the issue at hand, but I still don't understand where the original app is located and how I can access it and move it to Applications. I couldn't find it anywhere with both Finder search nor find command in terminal (I used $find / -name "HipChat*" -print). So, how does Adobe AIR store the installed applications (on OSX Lion) and is there any way to get them to show up in Launchpad?

  • Portable, battery-powered, wireless access point, ethernet adapter

    - by Jed
    I am in need of an adapter that will convert an ethernet port into a wireless access point. I have found a handful of devices, but I'm unable to find a device that is battery powered. Does a self-powered wireless access point even exist? The particular scenario that I will be using the device for is not your typical computer/PC scenario. For the curious, here's a bit of background on the problem I'm trying to solve: I make devices (controllers) that monitor water systems. Our controllers have a Webserver that serves out web pages so that users can configure the controller's settings. Typically, the user will use a cross-over cable to connect directly to the controller's ethernet port with their laptop to gain access to the controller's web pages. Now that tablets (devices that don't have an ethernet port - iPad, for example) are becoming more common, I need to find a device that will convert the controller's ethernet port into a wireless access point so that the user can connect to the controller's web pages via Wi-Fi or Bluetooth. It's worth noting that this wireless device that I'm looking for will NOT be permanently installed on the controller. It will be a portable device that the user will use on any of his controllers when he needs to make a connection to the controller. If you know of a device that will solve the scenario that I mention above, please share your info.

  • Backup with Mercurial and Robocopy?

    - by Andrew Neely
    The Problem We would like to backup our critical files from several network shares to a removable hard drive. We want to automate the backup so we don't have to remember to run it. It needs to finish overnight. Furthermore, we want to be able to preserve multiple versions of each file so we can back out of our user's mistakes easier. Background Information I work in a large Windows-based enterprise with a centralized IT section who is responsible for all backups. Their backups are geared towards disaster recovery and not user error, and require upper-level management approval for any non-disaster recoveries. Several times we have noticed that our backups have failed, we weren't notified. I do not have administrative rights to the server or my desktop. We are trying to backup some 198,000 files spanning about 240 gigabytes. These files rarely change. Our backup drive is one terabyte. My Proposed Solution What I would like to do is to write a batch file using Robocopy with the /mir option along with Mercurial SCM to store all versions of the file. I would do an hg add followed by an hg commit before each execution of Robocopy to save the current state, and then make a mirrored copy of the file structures. The problem is the /mir will delete every folder not present in the source, and Mercurial stores the repository in a .hg folder in the destination folder. Does anybody know how I could either convince Mercurial to store the .hg folder elsewhere, or convince Robocopy not to delete it from the destination? I'm trying to avoid writing a custom program do to copying.

  • Computer Comparison - which is "better"

    - by David Murdoch
    A company I work with recently replaced their old server and gave it to me. Their old server is a Dell PowerEdge 2600. I've been playing with the machine and even installed Windows Server 2008 on it...and it seems to run it pretty well. Here are the specs for the two machines: Dev Machine: AMD Athlon64 3000+ 2.38 GHz (overclocked from 1.8GHz [@ 280x8.5] - it is stable-ish) Memory (RAM): 1x1GB OCZ PC3200 (Dual-Channel) 300GB HD OS: Windows XP Pro (32bit) SuperPi 1M digit test: 40 seconds Dell PowerEdge 2600 Server: Intel Xeon CPU 2.8GHz 2.8GHz Memory (RAM): 512MBx2 (PC2700, not dual channel) 68GB HD (RAID 5) OS: Windows Server 2000 (32bit) SuperPi 1M digit test: 56 seconds [using 1 processor] (Themes and Aero-Flass UI turned off, of course) I use my computer to regularly run Photoshop CS5, Illustrator CS5, Flash CS5, 5 browsers (Chrome, FF, IE, Safari, Opera), iTunes, Visual Studio 2010, and Kaspersky Internet Security 2010 [sometimes simultaneously :-) ]. The SuperPi test has my dev machine coming in about 30% faster than the Server machine...though this could be due to the server running "Vista" with background processes prioritized. Do you think it would be realistic/advantageous for me to move from my dev machine to the Dell PowerEdge 2600? Is it possible to install additional DVD drives/burners on the server? Can I install my internal 300 GB hard drive on the server? Can I add some USB 2.0 ports? Note: I'll probably install Win XP Pro on the dev machine if I do switch. If not, are there any creative and useful way for me to take advantage of this server (with the goal of faster computing)?

  • Explorer.exe not starting after login on Windows Server 2003 (Terminal Services and console)

    - by Pepperoni Icecream
    When users login to a Windows Server 2003 R2 running Terminal Services they have a blank desktop. Upon inspection, explorer.exe is not running. When I login as administrator, using either RDP or to the console, I am having the same issue. I can pull up the taskman and start explorer.exe manually. I have another Terminal Server setup exactly the same way (same apps, settings, GPO, etc . . .) the only difference is we deployed Symantec Endpoint Client 11.0.5 on Friday. For some reason the working Terminal Server is still on 11.0.4, but the suspect server received the 11.0.5 client upgrade. I checked the eventviewer for any relevant explorer.exe entries to no avail. It seems that if SEP is preventing explorer.exe from starting at login it would do the same for the domain admin starting explorer.exe from the taskman. I disabled the SEP client and services on the server and issued smc -stop and tried logging in again. Still no explorer.exe. So I'm not sure if the client upgrade is relevant but it is worth mentioning since that was the last system change. The 2 servers are members of a NLB group. I took the bad terminal server out of the group until the issue is resolved. Actually stopped the host using NLB manager Any help is appreciated.

  • Password Cracking Windows Accounts

    - by Kevin
    At work we have laptops with encrypted harddrives. Most developers here (on occasion I have been guilty of it too) leave their laptops in hibernate mode when they take them home at night. Obviously, Windows (i.e. there is a program running in the background which does it for windows) must have a method to unencrypt the data on the drive, or it wouldn't be able to access it. That being said, I always thought that leaving a windows machine on in hibernate mode in a non-secure place (not at work on a lock) is a security threat, because someone could take the machine, leave it running, hack the windows accounts and use it to encrypt the data and steal the information. When I got to thinking about how I would go about breaking into the windows system without restarting it, I couldn't figure out if it was possible. I know it is possible to write a program to crack windows passwords once you have access to the appropriate file(s). But is it possible to execute a program from a locked Windows system that would do this? I don't know of a way to do it, but I am not a Windows expert. If so, is there a way to prevent it? I don't want to expose security vulnerabilities about how to do it, so I would ask that someone wouldn't post the necessary steps in details, but if someone could say something like "Yes, it's possible the USB drive allows arbitrary execution," that would be great! EDIT: The idea being with the encryption is that you can't reboot the system, because once you do, the disk encryption on the system requires a login before being able to start windows. With the machine being in hibernate, the system owner has already bypassed the encryption for the attacker, leaving windows as the only line of defense to protect the data.

  • Are Windows Domain Service Accounts Really Necessary?

    - by Zach Bonham
    One of the biggest problems we have in automating application deployments is the idea that running IIS AppPools and Windows Services under domain service accounts is a 'best practice'. Unfortunately, this best practice sometimes causes deployment headaches in that either we need to provision a new domain level service account quickly, or once we have the account, we now need to manage the account credentials. I had a great conversation about not making domain level service accounts a requirement and effectively taking one of two approaches: Secure at the node level using machine account(domain\machine$) and add the node to appropriate ActiveDirectory/Sql groups/roles Create local app specific accounts on each machine (machine\myapp) and add that account to appropriate ActiveDirectory/Sql groups/roles (the password here can change per deployment, it doesn't need to be stored) In both cases, it seems that its easier to manage either adding an account to appropriate group/role, or even stand up new, local account, than it is to have to provision a new domain level account and manage those credentials. This would hopefully ease the management burden on ActiveDirectory, Sql Server and Operations teams as there would be no more password management. We've not actually been able to implement this in practice yet. I am coming from a development background, so I'm curious as to how many ways this approach could go wrong? Can we really get rid of domain level service accounts with this direction? I'd appreciate any thoughts from anyone who has taken this path! Thanks! Zach

  • 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).
