• seamless mode remote desktop connection from linux to windows

  - by mateusz.fiolka

  I am a programmer using Linux as my main OS, however sometimes I need to use windows (ie, office, ea). I'm running qemu with kvm to access the windows "machine". I would like to achieve something that is described here: https://help.ubuntu.com/community/SeamlessVirtualization (It means I would be able to run chosen applications on Windows and then display them locally on Linux as separate windows achieving good desktop integration). However seamless rdp is buggy and doesn't work on my machine (probably because I'm using a tiling window manager and a 64bit system). Are you aware of any other solution then rdp seamless mode? I would prefer to still use quemu because it uses cpu hardware virtualization, so different protocol/client combination would be preferable.

• Updating Mcafee Group Shield on Exchange Server

  - by AllanPedersen

  So I don't actually have a problem yet, but I might. You see my fathers company have 10 computers and an exchange server with Mcafee Group Shield. lately they've had issues with mails from customers being blocked. I found both the problem and the solution: Mcafee update so basicly update their Mcafee group shield to the newest service pack and we are all back in buisness.. while I have some limited exchange experience and AD too. I don't have any Mcafee experience. I don't wanna crash their server for a week and have them need to get someone to recover it. So my question in here.. is it supposedly as easy as to click an 'update' button and to reboot your server.. or are there several issues I need to be aware about..? Maybe there is some common issue that goes with updating antivirus on an exchange server that I don't know about..

• How is a Chromebook better than using Chrome browser on another OS?

  - by bigpopakap

  I'm looking into getting a Chromebook as a lightweight device to use for basic functions. I'm fully aware of some of the limitations like no native apps, limited functionality while offline (though this is getting better with Google Drive's offline capabilities). Currently, I have a Windows machine on which I've installed Google Drive, so files in that folder are synced. And I use Chrome as my browser. So I have access to all the same apps (Drive, Calendar, Gmail, Google Music, etc.). Is there any advantage to having a Chromebook over my current setup, other than the speed of the lightweight Chrome OS?

• What software can I use to create a video of following type?

  - by Bond

  Here is a video on this link http://www.youtube.com/watch?v=kSx873lOgIc&feature=player_embedded#at=62 Someone among my bosses wants to create some thing similar to the video on above link and has asked me what software can they use to do the same.The purpose is to create educational content only.Which can have the demonstrations (animations ) and audio also running in backend. I am not clear as what software can be used for this on Linux or Windows. I have users which use Windows and Linux both. I have used video editing on Mac using Final Cut Pro but the video on the above link is not some thing which can be achieved with FCP.(Or may be I am not aware) I am looking solution for 1) Linux users 2) Windows users In case of Linux it is Ubuntu for some users and Fedora for some others. I am a Linux guy so I am specifically posting this question in terms of Ubuntu but I also need suggestions for Windows type of users.I have no clue of such video animations at all.

• Configure Postini and emailreg.org

  - by crn

  One of our companies uses Postini services as our spam filtering service. Unfortunately, the company has been tagged as a spammer and we're trying to use emailreg.org to whitelist us. Emailreg.org wants us to add a CNAME which points to their domain (emaireg.org), while Postini has us add MX records (such as domainname.s7a1.psmtp.com. Here are my questions: 1. Can adding Emaireg's CNAME cause either Postini to not work or our emails to be lost? 2. Which is order of execution (do the email go to Postini and upon their return to EmailReg or is it the other way around)? 3. Is there anything of which I should be aware when using such a setup? Thanks, in advance, for all your help!

• How can I get the size of an Amazon S3 bucket?

  - by Garret Heaton

  I'd like to graph the size (in bytes, and # of items) of an Amazon S3 bucket and am looking for an efficient way to get the data. The s3cmd tools provide a way to get the total file size using s3cmd du s3://bucket_name, but I'm worried about its ability to scale since it looks like it fetches data about every file and calculates its own sum. Since Amazon charges users in GB-Months it seems odd that they don't expose this value directly. Although Amazon's REST API returns the number of items in a bucket, [s3cmd] doesn't seem to expose it. I could do s3cmd ls -r s3://bucket_name | wc -l but that seems like a hack. The Ruby AWS::S3 library looked promising, but only provides the # of bucket items, not the total bucket size. Is anyone aware of any other command line tools or libraries (prefer Perl, PHP, Python, or Ruby) which provide ways of getting this data?

• Desktop speakers with headphone port and separate volume controls

  - by Kevin L.

  I currently use the excellent Logitech X-230 desktop speaker/subwoofer set, which I love for the volume dial on the front which gives me a nice, quick, tactile control of my sound without requiring a remote or keyboard buttons or some awkward software slider. Additionally, there's a very convenient headphone jack right next to the volume dial but the volume dial only controls the speakers, leaving the headphones at full volume. The goal is to be able to adjust the sound in my headphones without having to fumble around and find an inline headphone volume control (and my current favorite pair doesn't even have one). Is anyone aware of a desktop speaker set that has convenient volume controls for both levels?

• DOS application to allow remote management of files over serial link

  - by tomlogic

  Harken back to the days of DOS. I have an embedded DOS handheld device, and I'm looking for a tool to manage the files stored on it. I picture an application I can launch on the device that opens COM1 up for commands to get a directory listing, send/receive files via x/y/zmodem, move/delete files, and create/move/delete directories. A Windows application can then download a recursive file listing and then manage those files (for example, synchronizing with a local directory). Keep in mind that this is DOS -- 8.3 filenames, 640K of RAM and a 19200bps serial link (yuk!). I'd prefer something with source in case we need to add additional features (for example, the ability to get a checksum of a file for change detection). Now that I've written this description, I realize I'm asking for something like LapLink or pcAnywhere. Norton no longer sells DOS versions of pcAnywhere and LapLink V for DOS seems pricy at $50. Are you aware of any similar apps from those good old days?

• Exchange 2010: How to retain mail in the outgoing queue for a certain amount of time before it is being sent

  - by Jeroen Landheer

  One of our clients asked us to configure Exchange 2010 to retain outgoing mail for a certain amount of time (independant of Outlook settings.) The idea is that an administrator has about 10 minutes to take a message out of a queue before it is sent out the organization. I know this can be configured in Outlook, but this is not a valiable solution for us. I'm also aware that this causes queues to fill up, this is part of the consideration. Is there a way in Exchange 2010 to configure this?

• Virtualhosts - best way of dealing with it?

  - by axqe56

  I'm competent at the basics of Apache, PHP and virtual hosting but have a question about virtual hosting. As far as I'm aware, HOSTS files can only be in one of the following locations: C:/Windows/system32/drivers/etc (varies in older installs, I believe) I don't think it can be put elsewhere for use with Apache, simply for virtual hosts, and the main HOSTS file for blocking sites etc. I heard about PAC files on Uniform Server's website (http://wiki.uniformserver.com/index.php/Virtual_Hosting:_PAC) but they're browser-specific though, aren't they? What's the best way to deal with virtualhosts, other than HOSTS file? My server isn't currently open to the internet yet, but if it is, what's the best way to resolve DNS for my virtualhost domains if it were to become forward-facing (i.e open to the internet)?

• How can HAProxy improve availibility, or "how can I prevent my site from going down"? [closed]

  - by Joe Hopfgartner

  I am aware of what HAProxy does, but what if my HAproxy goes down? Or what if my DNS servers go down? Yes, dns is less the problem. However dns only solves to an IP and an IP is announced via BGP to be routed over some router. What if that router goes down? Of course if I have complicated application servers that are likely to fail HAProxy can significantly improve uptime. But my application isnt. In fact my application may very well just be delivering a small static html file via HTTP. Basically if any user anywhere types in MYDOMAIN.COM, I want the user to get SOMETHING on the screen other than a timeout or DNS resolution error. How can I do that? The point of entry is difficult. The so called "initial closure mechanism".

• Fonts not found when print request comes from a child process of a Service

  - by beeglebug

  I have a strange issue on a Windows Server 2003 box which has been baffling me for days now. I have a service running on the machine which calls a specified exe every 60 seconds, the exe looks at a local database to see if it needs to print anything, and if so, it prints it to a network laser printer. The problem i'm having is that some fonts won't print out when the exe is called automatically by the service, but work fine if I double click the exe to run it. The font was installed by Administrator, but the service runs as NT Authority\System. I thought this might have something to do with it, but I tried running the service as Administrator, and that didn't solve it. Are there any issues with fonts and permissions that i'm not aware of that could be causing this behaviour?

• What is the `shadow` group used for?

  - by Shtééf

  On my Ubuntu 9.10 system, there's a shadow system group. There does not appear to be any user assigned to this group at all. The only files that I can find belonging to this group are /etc/shadow and /etc/gshadow. I'm aware that the purpose of these files is to store the passwords separately, out of reach from regular users who still might want to access passwd for other reasons. But what is the purpose of the shadow group? The reason I'm curious about this, is because I'm thinking about configuring nsswitch.conf to store it elsewhere, and would like to know if anything is actually trying to access the shadow database using shadow group credentials.

• ZFS, dedupe and PST files

  - by Unreason

  I am interested to know what would be expected maximum dedupe ratio for a set of PST files. I have ~40G of pst files from ~15 usres with high level of duplication of attachments. I am running tests to see if I can have significant space savings if I store the data on ZFS with dedupe. For this purpose I have installed a test setup of Nexenta, but was wondering if someone here had already done this and what level of deduplication I might expect (or in another words how sensitive are pst files to block alignment and what are the parameters that can influence the ratio?). Initial test show very low dedupe ratio and I did find explanation that block level dedupe would not be efficient here and that byte level dedupe would be much better (and that it should be performed by application that is aware of internal organization), so I am just double checking here if someone have some more input. Otherwise I will probably be converting PST files to IMAP.

• Vim - select text highlighted by search?

  - by GorillaSandwich

  In vim, I often perform searches to hop to a word or phrase instead of navigating there with h/j/k/l. Then I hit n to hop between occurrences. Say I've got this text: Time flies like an arrow; fruit flies like a banana. - Groucho Marx I type /an arrow and hit enter. That phrase is highlighted, and I jump to it. Now I want to visually select that text, maybe to change it or delete it. (Yes, I'm aware of the :s substitution command.) Since my cursor is at the letter "a" at the beginning of "an arrow," I can hit v, then press e a couple of times to highlight the entire phrase. But I have a feeling there's a shorter and more semantic way. After all, I've already specified the text I'm interested in. How might I compose a command to say "visually select the current search selection?"

• Has anyboy been able to install Pantograph for Blender on Windows?

  - by S.gfx

  I am specially interested on if somebody is actually doing/maintaining an installer for Windows, as there are quite several issues when installing all dependencies, etc. (for example, there might be someone already doing a Installbuilder installer for it and am just not aware of the matter) If not, at least if someone got it working and has some key tip to share. I am never able to fully get it all up and running. I'd love to have a not super complex way to install each new build of this great vector rendering module for Blender. Edit- Pantograph url: http://severnclaystudio.wordpress.com/bluebeard/a-users-guide-to-pantograph/

• Can only connect to sql server express 2012 via named pipes

  - by YetAnotherDeveloper

  I have sql server express 2012 installed on windows 2008, locally everything works just fine i can connect via tcpip and named pipes. Remotely i can connect with ssms only using named pipes. I have tried disabling the firewall on both sides to eliminate blocking traffic. i have toggled the tcpip setting on and off (i read somewhere that they got it working just but flipping them off and back on). I have double/triple checked all the settings that i'm aware of and everything seems to be correct. Tcp is enabled Tcp port is set to 1433, udp port is set to 1434 Server has static ip Start up log says: Server is listening on [ 'any' 1433]. Firewall rules are in place Any suggestions on things that i can look into? i have really just run out of ideas.

• Trouble "turning off" dialtone in Exchange 2010

  - by makerofthings7

  Given that there are two ways to enable dial tone, I'm having trouble turing it off. The two ways I'm aware of are: Dismount the database, delete it or rename it, mount it, Exchange will prompt for a dial tone creation. Run the command: Get-Mailbox -Database DB1 | Set-Mailbox -Database DTDB1 as described here Both options should result in Outlook "thinking" it's in dial tone mode. Since my goal is to shut off dial tone, I think I need to learn the specific, technical parameters that "tell" Outlook that it is in dial tone mode. Question How can I turn off dial tone for a given database? What tells outlook that it's in dial tone mode?

• Lots of files being used by blank web page. What are they?

  - by byronyasgur

  I am trying to optimise a website and I was using the network waterfall facility in Google Chrome. When I looked at the results there were lots of files which I didnt recognise. I first thought they might be something to do with Google Chrome itself, so I put a blank HTML file on my desktop and checked but there was nothing in the waterfall except the file itself. So I put a blank file on my server and I got the output below. What are all these files, are they all necessary, is this normal and do I need to be in any way concerned. My hosting provider has always been excellent in every regard that I'm aware of. My host is shared hosting, using cpanel and is based on a LAMP server. I also note that a couple of those file have problems but I have no idea how to fault find that or whether it's a concern. EDIT: I have cleared the cache so I don't think it's a browser cache issue.

• How to select the account on the login screen of Windows7 by start typing the name?

  - by akira

  When MacOS boots up and the users is prompted to select the account (s)he wants to login into, the users can either click the name / icon of the account with the mouse or just type in the name of the account. I want to do the same at the login screen of Windows7: Login screen pops up, I start to type my account name, I select the account with enter and then I type the password and enter again. No usage of the mouse involved. (I am aware of tab-cycling and hard-to-follow-the-almost-invisible-marker-of-where-the-focus-is-right-now)

• How do I connect a laptop running Windows 7 to an Android phone using WiFi Direct?

  - by user130768

  From where I am sitting, Windows 7 does not appear to support WiFi Direct connections to Android mobile devices. Specifically, turning on WiFi Direct on my Samsung Galaxy S II does not make the device visible as a potential WiFi network connection. Windows 8 is said to support WiFi Direct, but I have no desire to upgrade at this time. I have successfully set up ad hoc WiFi connections between the S II and my laptop before, but as you may be aware, these are not the same as WiFi Direct. Before posting this question, I searched [ "Windows 7" "WiFi Direct" ] and variations thereof, and dutifully slogged through dozens of lame or irrelevant responses on various forums, badly made YouTube videos, and probable Trojan horse distribution sites. If someone out there knows how to do this, it's buried in the noise.

• ISA bus on newer computers

  - by Kevin Ivarsen

  Are there companies that sell new computers that support old ISA bus expansion cards? We have an aging computer running DOS that operates some machinery via an ISA interface board. Updated versions of this board (e.g. PCI, USB) are not available, and I am concerned about the long-term reliability of the 8+ year old computers we currently keep around as backups. If these newer ISA-capable machines exist, are there any general gotchas to be aware of in terms of compatibility with older expansion boards, ability to run DOS, etc.?

• Is there an equivalent to Windows To Go for personal use?

  - by nhinkle

  Windows To Go is one of the most exciting Windows 8 features to me - the ability to pack up your desktop environment and take it with you anywhere is extremely appealing. Unfortunately, it's only included with Windows 8 Enterprise, which you can't buy for individual use. Is there an equivalent that works for Windows 8 Professional? I would be satisfied by either a third-party program that does the same thing, or some workaround to enable Windows To Go for non-Enterprise versions. I'm aware of various WinPE-based live environments, and that's not what I'm looking for. I want the ability to run a full Windows 8 environment off of a flash drive that I can take anywhere.

• Apache and fastcgi - How to secure an Apache server with fastcgi enabled?

  - by skyeagle

  I am running a headless server on Ubuntu 10.x. I am running Apache 2.2. I am writing a fastcgi application for deployment on the server. I remember reading a while back (I could be wrong) that running CGI (and by implication fastcgi) on a server, can provide 'backdoors' for potential attackers - or at the very least, could compromise the server if certain security measurements are not taken. My questions are: what are the security 'gotcha's that I have to be aware of if I am enabling mod_fastcgi on my Apache server? I want to run the fastcgi as a specific user (with restricted access) how do I do this?

• How to script printer creation on a Windows Server 2008 R2 clustered print server?

  - by Massimo

  As per subject. I've found some ways of scripting printer creation on Windows print servers using WMI, but it looks like WMI doesn't support clustered print servers (or clustered servers at all). The scripts in C:\Windows\System32\Printing_Admin_Scripts are useless because, they are not cluster-aware and end up creating the printers on the active cluster node (just like using WMI). The only tool I found that was able to work on a clustered print server is printui.exe (shortcut for rundll32 printui.dll, PrintUIEntry), but it can't create TCP printing ports: it can only add printers if the port already exists. How can I completely script printer creation (including TCP printing ports!) on a clustered Windows Server 2008 R2 print server?
