  • How can adding a server to a domain cause Remote Desktop to stop working?

    - by Adrian Grigore
    I have two dedicated with Windows 2008 R2 servers which I am using for Web hosting. One Server A is a domain controller, Server B should simply be added to the domain controlled by Server A. So I RDP'd into Server B and changed the system settings so that Server B is part of that domain. I entered my domain admin credentials, was welcomed to the domain and asked to reboot the server. So far everything seemed to work smoothly After rebooting, I could not open an RDP connection to Server B anymore: Remote Desktop can’t connect to the remote computer for one of these reasons: 1) Remote access to the server is not enabled 2) The remote computer is turned off 3) The remote computer is not available on the network Make sure the remote computer is turned on and connected to the network, and that remote access is enabled. I restored an older backup of Server B and switched off the firewall before adding the server to my domain. But the problem reoccurred just the same. What could be the reason for this? The domain is brandnew and I did not change any of the default settings. Could this be some kind of domain-wide default policy that shuts down RDP on any domain clients? Or perhaps it has to do with the fact that Server B is virtual? Thanks for your help, Adrian

  • User Crontab + Python + Random wallpapers = Not working?

  • Diagnose remote desktop freezes in Windows 7 when no BSOD?

    - by Paul Smith
    Okay, I'm getting no joy from Asus or Microsoft on this, so hoping for some clues on how to narrow down the cause. I have very frequent OS freezes, always & only when running Remote Destkop Client (mstsc) in Windows 7 x64. I never have a bluescreen, and there is never a minidump. The display & input just freezes -- no keyboard, no mouse, and sound will just continue the last wavelength if any. So far, I can't find a way to trap the hang given that there's no bluescreen; advanced startup & recovery settings for system failure are "Write an event" checked, "Automatically restart" checked, and "Kernel memory dump". I've updated to the lasted BIOS, and tried a few different graphics drivers, both generic & ATI. I've also tried disabling Aero, and everything about the remote desktop experience (incrementally unchecked every box in the mstsc - options - experience tab), even disabled/unplugged external monitor to make sure it wasn't a dual-monitor issue. My specs are: Asus G73jh notebook 8GB RAM ATI Mobility Radeon HD 5800 Series graphics (recently tried driver versions 8.791.0.0, 8.801.0.0) American Megatrends G73jh.211 BIOS (7/27/2010) Windows 7 Home Premium x64 Windows Memory Diagnostic passed all of the following at least 3 times with no errors: MATS+ INVC LRAND Stride6 WMATS+ WINVC This notebook is better than most at removing heat (laudable vent design), so I'm not inclined to suspect thermal causes (especially since running 1080p video for hours has never caused a freeze, but mstsc does, reliably, within 5 minutes to an hour). This did seem to start happening after a Windows Update, but I've since reverted every patch applied since a week before the first occurrence, with no joy. (And I'd only had the PC for a couple weeks before that, so it could have been chance + less actual time spent remoting at the beginning.) I'm at my wits end, and I bought this laptop primarily as a remote terminal client (go figure, right?) Any ideas on how to identify the cause of this? Thanks!

  • Does Xenapp require Windows Terminal Services (Remote Desktop) licenses?

    - by John Virgolino
    We have a Xenapp 5.x server running for over a year now. It does not have any purchased Terminal Services (Remote Desktop) licenses installed. It is running on a Windows 2008 Server box. I am aware that Terminal Services runs fine for about 3 months and then supposedly stops issuing licenses. On occasion, Xenapp stops working and we see lots of License errors in the event log, although not necessarily every time. In most cases, a reboot or 2 resolves the problem. We figured it was because of the lack of TS licenses. I spoke with Citrix and they said we had to have the licenses, but it begs the question that if we have to have the licenses, how does it work the majority of the time without them!!?? I have not received a straight answer yet and before I tell my client to shell out more money, I need to understand the technical reasoning for how this is actually working if we are breaking the rules here. We will buy the licenses if necessary, but there has to be an explanation for this. I am hoping the community can help where Citrix apparently cannot. Thanks much!

  • How to make a redundant desktop system with daily snapshots? (Is btrfs ready for use?)

    - by TestUser16418
    I want to configure a desktop system in which the home filesystem would be redundant (e.g. RAID-1), and would have weekly snapshots taken. I've already done this with ZFS, the snapshot system is wonderful, and with send/recv you can easily create backups on external media. Unfortunately, at that point, I want GNU+Linux and not FreeBSD or Solaris, so I'm looking for suggestions for good alternatives. I reckon that my alternatives are: btrfs - it seems to be exactly what I need, it has snapshots and commands that allow you to easily replicate zfs send. Yet all documentation mentions that it's still experimental. I can't seem to find any actual reports on its reliability or usability issues. Can you point me to any information on that issue that could clarify whether it would be a possible choice? I have a large preference for this option, mostly because I don't want to reformat the drives when btrfs becomes ready, but I there's no information on whether it's usable at all, whether it's a silly idea to use it, etc. The question that I cannot get the answer to is what does "experimental" mean. lvm snapshots and ext4 - preferably not, since it can consume an awful amount of space when new files are created. Creating 200 GB files requres 200 GB free space and 200 GB additionally for snapshots. I also have found it unreliable -- failed metadata rewrite results in an unreadable PV. I'm wondering how btrfs would compare here. A single filesystem (ext4) on a RAID-1 array with custom COW snapshots with hardlinks (like cp -al). That's my current preference if I can't use btrfs. So how experimental btrfs is, which should I choose, and do I have any other options? What if I don't keep external incremental backups, would that affect my choice?

  • Python/Sqlite program, write as browser app or desktop app?

    - by ChrisC
    I am in the planning stages of rewriting an Access db I wrote several years ago in a full fledged program. I have very slight experience coding, but not enough to call myself a programmer by far. I'll definitely be learning as I go, so I'd like to keep everything as simple as possible. I've decided on Python and SQLite for my program, but I need help on my next decision. Here is my situation 1) It'll be a desktop program, run locally on each machine, all Windows 2) I would really like a nice looking GUI with colors, nice screens, menus, lists, etc, 3) I'm thinking about using a browser interface because (a) from what I've read, browser apps can look really great, and (b) I understand there are lots of free tools to assist in setting up the GUI/GUI code with drag and drop tools, so that helps my "keep it simple" goal. 4) I want the program to be totally portable so it runs completely from one single folder on a user's PC, with no installation(s) needed for it to run (If I did it as a browser app, isn't there the possibility that a user's browser settings could affect or break the app. How likely is this?) For my situation, should I make it a desktop app or browser app?

  • Will Learning C++ Help for Building Fast/No-Additional-Requirements Desktop Applications?

    - by vito
    Will learning C++ help me build native applications with good speed? Will it help me as a programmer, and what are the other benefits? The reason why I want to learn C++ is because I'm disappointed with the UI performances of applications built on top of JVM and .NET. They feel slow, and start slow too. Of course, a really bad programmer can create a slower and sluggish application using C++ too, but I'm not considering that case. One of my favorite Windows utility application is Launchy. And in the Readme.pdf file, the author of the program wrote this: 0.6 This is the first C++ release. As I became frustrated with C#’s large .NET framework requirements and users lack of desire to install it, I decided to switch back to the faster language. I totally agree with the author of Launchy about the .NET framework requirement or even a JRE requirement for desktop applications. Let alone the specific version of them. And some of the best and my favorite desktop applications don't need .NET or Java to run. They just run after installing. Are they mostly built using C++? Is C++ the only option for good and fast GUI based applications? And, I'm also very interested in hearing the other benefits of learning C++.

  • Java vs. C variant for desktop and tablet development

    - by MirroredFate
    I am going to write a desktop application, but I am conflicted concerning which language to use. It (the desktop application) will need to have a good GUI, and to be extendable (hopefully good with modules of some sort). It must be completely cross-platform, including executable in various tablet environments. I put this as a requirement while realizing that some modification will no doubt be necessary. The language should also have some form of networking tools available. I have read http://introcs.cs.princeton.edu/java/faq/c2java.html and understand the differences between Java and C very well. I am looking not necessarily at C, but more at a C variant. If it is a complete toss-up, I will use Java as I know Java much better. However, I do not want to use a language that will be inferior for the task I wish to accomplish. Thank you for all suggestions and explanations. NOTE: If this is not the correct stack for this question, I apologize. It seemed appropriate according to the rules.

  • opening socket to google hangs on SYN_SENT

    - by puchu
    I have 2 computers now: downloader (asus at4nm10t-i) with debian and desktop (asus sabertooth 990fx) with gentoo in the same network under NAT even with the same ethernet card: RTL8111E. driver r8169 is compiled as module on both computers. Sometimes in evenings desktop cannot connect to google and all its services like now: curl -v http://www.google.by on downloader it received server's answer immediately. on desktop it hanged and when I ran in other terminal: netstat -ntp | grep curl >>tcp 0 1 192.168.0.7:54126 173.194.35.191:80 SYN_SENT 4876/curl after 1-2 minutes it received server's answer. I was tried to change ip of network, mac address of desktop but nothing changed. When I was trying to connect to another services except google: curl -v http://www.yahoo.com both computers received answers immediately! Only when I rebooted desktop it begins to work with google services correctly I cant understand what is this bug related to. In which bugtracker should I post this: r8169 or linux kernel or google? PS. Desktop was checked with memtest: 5 passes - no errors

  • Effect of HOME on libreoffice to convert to pdf as non-root user

    - by user1032531
    I installed libreoffice-headless and can convert documents when logged on as root. I then tried doing so as another user, and it didn't show an error, but didn't convert the file. I then found that if I get rid of the HOME=/tmp/ayb, it works with the other user. Doesn't HOME=/tmp/ayb just allow files to default to this directory if not specified? (Sorry, I tried to search "Linux HOME", but as you probably expect, received a bunch of non-relevant results). If not, what is the purpose of specifying HOME? Why does setting HOME prevent it from converting on non-root users? Note that /tmp and /tmp/ayb or both 0777.

  • Tunneling traffic through two VPN hops/tunnels.

    - by Roberto Sebestyen
    I am a web developer, and I find myself often working from home. But when I do, I am forced to Remote Desktop to the Office desktop computer and work from there. The reason is because the application I am working on needs to connect to servers at a Data Center via a VPN from the Office Desktop. HomeDesktop (Win7) --- PVN --- OfficeDesktop(WinXP) --- VPN --- Data Center What I would really like to do is, I would like to find a way to be using my Home desktop developing on that, and whenever my computer tries to access servers on the Data Center, I would like to tunnel that traffic through the two VPN tunnels separating me and the Data Center. I have admin privileges on both Office Desktop and Home Desktop, but I do not have any admin privileges in the Data Center. So what kind of tunneling solution could I use here? Is it even possible?

  • windows - batch moving files to another folder/directory

  • How do I re-install Unity after uninstalling gnome-shell?

    - by Florian
    I am using Ubuntu 14.04. I have big issues with the Unity desktop. I installed then uninstalled gnome-shell (using "apt-get autoremove --purge gnome-shell"). Since then, my desktop has no background and no icons. Plus, and this is the bothering part, unity is very unstable. On startup, there is a huge use of memory, much more than before. Sometimes, I also cannot minimize a window without having the desktop freezing and having to kill the process in question with tty1. I have tried to use : apt-get autoremove --purge ubuntu-desktop apt-get install ubuntu-desktop But it does not change a thing. I tried to update my video drivers but it is still the same. How can I reinstall the unity desktop thoroughly (obviously, something in its install is broken) ? If it is not possible, is it safe that I create a new partition on my disk where I will put my files and reinstall Ubuntu on the old partition (I do have a USB install of Ubuntu 14.04 but not enough space to save my files on it) ?

  • Ubuntu 12.04 LTS: Error message "Failed to execute child process"

    - by Ron
    I am an Ubuntu-newbie and just started working with Ubuntu (version 12.04 LTS) a couple of days ago. I wanted to add a launcher icon to desktop for launching an application I previously installed. Up to now I can only launch it by typing setsid matlab -desktop into my terminal. Now there is the following problem with the execution via the desktop icon: Whenever I click the desktop icon, I get the following error message: "Failed to execute child process" I would like to add a screenshot, but unfortunately as a new user, I am not allowed to... In the main menu from where I added the icon via drag'n'drop to desktop there is also a permission to execute the .desktop file. I also tried to look for advice on the error message "Failed to execute child process..." but could not find anything useful. Now does anybody have an idea what I am missing? Sorry if this is a stupid question ;) ...but as I just said: I just started with Ubuntu... Thanks to everybody in advance for their help! :) And let me know if you should need any more information...

  • How to sync Ubuntu/software/configurations between N computers with free software and/or without a cloud?

    - by skanatek
    Note: this question is not about syncing data in a Dropbox-like way (files, folders), it is more about syncing configurations. I would like to have exactly the same version of Ubuntu with all the software installed and configured both on my Desktop PC and on my Laptop PC (and maybe on my small netbook PC) without using Ubuntu Sync and with minimal maintenance effort (setup once, run for a long time). The use case is the following: I work on my Laptop PC and do some changes to software configuration, for example: configure vim to have a new plugin update the Search Tracker / Recoll file search index configure Thunderbird to have an additional IMAP account ('remember password') add some new bookmarks in Firefox/Chrome change the desktop background image install new software with apt-get install build and install new software with checkinstall etc. I do some 'sync' operation I switch to my Desktop PC and get all the changes from (1) working on the Desktop PC I work on my Desktop PC and do some changes to software configuration, for example: add new directory to the list of directories to be backed up by DejaDup add a new check spelling dictionary to the Libreoffice Writer configure the Terminator software to have colored fonts install new font into the Ubuntu system configure Ekiga to make phone calls etc. I do some 'sync' operation I switch to my Laptop PC and get all the changes from (1) and (4) working on the Laptop PC. Question: What free/open-source software can I use to sync both machines' Ubuntu systems, installed software and configurations? Is it possible to do that without any cloud services? Complementary question: It is obvious that the Desktop PC and the Laptop PC have different hardware configurations. How does the 'sync software' in question deal with video drivers, wlan drivers and their configurations? Note: I do not need all the PCs to be synced at the same time, because I work with only one single machine at once. Note: I considered to use Chef to solve the problem, but it seems that it might be really cumbersome to maintain such a setup. Note: I also considered using a bootable USB with Ubuntu installed (portable Linux), but I am not sure that the video drivers will work then.

  • Misconceptions about purely functional languages?

    - by Giorgio
    I often encounter the following statements / arguments: Pure functional programming languages do not allow side effects (and are therefore of little use in practice because any useful program does have side effects, e.g. when it interacts with the external world). Pure functional programming languages do not allow to write a program that maintains state (which makes programming very awkward because in many application you do need state). I am not an expert in functional languages but here is what I have understood about these topics until now. Regarding point 1, you can interact with the environment in purely functional languages but you have to explicitly mark the code (functions) that introduces them (e.g. in Haskell by means of monadic types). Also, AFAIK computing by side effects (destructively updating data) should also be possible (using monadic types?) but is not the preferred way of working. Regarding point 2, AFAIK you can represent state by threading values through several computation steps (in Haskell, again, using monadic types) but I have no practical experience doing this and my understanding is rather vague. So, are the two statements above correct in any sense or are they just misconceptions about purely functional languages? If they are misconceptions, how did they come about? Could you write a (possibly small) code snippet illustrating the Haskell idiomatic way to (1) implement side effects and (2) implement a computation with state?

  • JRuby wrong element type class java.lang.String(array contains char) related to JAVA_HOME

    - by Daryl
    I am on Ubuntu x64 bit running: java version "1.6.0_18" OpenJDK Runtime Environment (IcedTea6 1.8) (6b18-1.8-0ubuntu1) OpenJDK 64-Bit Server VM (build 14.0-b16, mixed mode) and jruby 1.4.0 (ruby 1.8.7 patchlevel 174) (2010-02-11 6586) (OpenJDK 64-Bit Server VM 1.6.0_18) [amd64-java] I have this code running on my Windows 7 computer at home. I recently copied over my whole folder over to Ubuntu, installed java, jruby, and associated gems but I get this error when I run my main file: jruby run.rb test =================Processing FREDERICKSBURG_1.1======================= ERROR IN TESTING wrong element type class java.lang.String(array contains char) /home/daryl/Desktop/work/Code/geografikos/lib/sentence_splitter/splitter.rb:21:in `to_java' /home/daryl/Desktop/work/Code/geografikos/lib/sentence_splitter/splitter.rb:21:in `split' /home/daryl/Desktop/work/Code/geografikos/lib/models/page.rb:103:in `sentences' /home/daryl/Desktop/work/Code/geografikos/lib/extractor/lingpipe_svm.rb:34:in `extract' /home/daryl/Desktop/work/Code/geografikos/lib/extractor/geo_controller.rb:9:in `process' /home/daryl/Desktop/work/Code/geografikos/lib/extractor/geo_controller.rb:8:in `each' /home/daryl/Desktop/work/Code/geografikos/lib/extractor/geo_controller.rb:8:in `process' /home/daryl/Desktop/work/Code/geografikos/lib/extractor/geo_controller.rb:6:in `each' /home/daryl/Desktop/work/Code/geografikos/lib/extractor/geo_controller.rb:6:in `process' /home/daryl/Desktop/work/Code/geografikos/lib/statistics.rb:111:in `generate_all' /home/daryl/Desktop/work/Code/geografikos/lib/statistics.rb:105:in `each' /home/daryl/Desktop/work/Code/geografikos/lib/statistics.rb:105:in `generate_all' run.rb:56 The focus of the error is: ERROR IN TESTING wrong element type class java.lang.String(array contains char) Everything works fine on my windows machine. I figured I was getting this error because I did not have JAVA_HOME set however I added this to bashrc as: export JAVA_HOME=/usr/lib/jvm/java-1.6.0-openjdk and have confirmed: echo $JAVA_HOME /usr/lib/jvm/java-1.6.0-openjdk I can produce a similar error by removing my JAVA_HOME variable on windows: =================Processing FREDERICKSBURG_1.3======================= ERROR IN TESTING cannot convert instance of class org.jruby.RubyString to char C:/work/Code/geografikos/lib/sentence_splitter/splitter.rb:21:in `to_java' C:/work/Code/geografikos/lib/sentence_splitter/splitter.rb:21:in `split' C:/work/Code/geografikos/lib/models/page.rb:103:in `sentences' C:/work/Code/geografikos/lib/extractor/lingpipe_svm.rb:34:in `extract' C:/work/Code/geografikos/lib/extractor/geo_controller.rb:9:in `process' C:/work/Code/geografikos/lib/extractor/geo_controller.rb:8:in `each' C:/work/Code/geografikos/lib/extractor/geo_controller.rb:8:in `process' C:/work/Code/geografikos/lib/extractor/geo_controller.rb:6:in `each' C:/work/Code/geografikos/lib/extractor/geo_controller.rb:6:in `process' C:/work/Code/geografikos/lib/statistics.rb:111:in `generate_all' C:/work/Code/geografikos/lib/statistics.rb:105:in `each' C:/work/Code/geografikos/lib/statistics.rb:105:in `generate_all' run.rb:56 It is obviously not exactly the same but I have a feeling this has to do with the java path. You can probably derive from the error that I am just trying to convert a ruby variable to java using to_java. This works fine on my windows machine and I have confirmed the gems are the same but I don't think this has to do with gems. I lied. I changed my JAVA_HOME back on my windows machine and this error still occurs. So now the code doesn't run on either machine. I recently installed git on my windows machine and added the code to a repository. But I haven't really done anything with it. All it said was it will convert all LF to CRLF...That shouldn't change anything though should it? Any ideas on why I am now getting these errors? I haven't changed anything on my windows machine in months except for installing git.

  • When I log on to my company desktop, I log on to a domain. How is this domain name installed?

    - by learnerforever
    Hi, When I have to work on my machine in company, I have noticed that I log on to a domain (named on the basis of company name) and not really on that computer. From, what I understand, this has a few advantages, the primary being that I just need one password for the domain and can work through any of the machines in company. My questions are : What software on desktop/network have to be installed so that the desktop recognizes and gives me option of logging into a domain. I would guess that a software can be installed on desktop, and there we can configure the IP address of domain server of company and port number, which handles authentication. Is this correct? This takes me to another question that how are softwares installed on end machines in a company. Going to each machine physically and installing looks very unweildy from administrator point of view. An obvious solution would be to install softwares (and updates) over network. My question on this are: What protocols,keywords come into picture when administrator installs OS,softwares,updates from his administrator machine to end machine through network. Thanks,
