  • Windows 2003 Active Directory Integrated DNS zone not registering non-domain computers

    - by Jeff Willener
    I'm not a networking guy by all means, I'm just a developer who dabbles enough to get into trouble and I'm there. So bear with me... :) At my office I have a Windows 2003 Domain Controller which also services DNS. On the domain I have a handful of computers and other misc. equipment/toys. For the DNS I only created a Forward Lookup Zone for my domain (mydomain.com). I run a lot of VM's so generally I have everything on the domain, however some of those VM's are not and only in a 'Workgroup'. I also have another laptop which belongs to another domain (otherdomain.com) which is here 100% but I use it for other purposes and has to belong to the otherdomain.com. With all that said, I have two questions: I have found any computer not on mydomain.com does not register it's IP address even though 'Register this connections address in DNS' is set to in the 'Advanced TCP/IP Settings' for the nic. Where have I messed this up? On the laptop which is registered on otherdomain.com, when I do a nslookup for a computer on mydomain.com (e.g. nslookup devbox1) it appends otherdomain.com as the suffix (e.g. queries devbox1.otherdomain.com). Same thing occurs if I use the fully qualified name. In the 'Advanced TCP/IP Settings' for that nic, I can 'Append these DNS suffixes' of mydomain.com but I fear that will hose my DNS lookups when I VPN to otherdomain.com. So what is the correct approach to resolve this issue? Do I add both mydomain.com and otherdomain.com in that order?

  • Windows XP laptop doesn't appear in WSUS All computers list

    - by George
    I have this one laptop that doesn't appear in WSUS all computers list. We have about 23-25 PCs/laptops/servers in the network, all, but one are listed in WSUS. This is what I have done so far: 1) Changing Updates on local PC: Go to your Windows XP client and start a new Microsoft Management Console (MMC). At Start, Run, type MMC. Use Ctrl+M to add a new snap-in. Click Add, and then add the Group Policy Object Editor for the Local Computer. Click Close, and then click OK. Expand the Local Computer Policy. Under Computer Configuration, go to Administrative Templates, Windows Components, Windows Update. In the right-hand pane, double-click Specify intranet Microsoft update service location. Configure the settings to reflect my WSUS server. Click OK and then close the MMC without saving it. executed wuauclt.exe /detectnow 2) Edited registry key to be pushed to the PCs using GPO [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate] "WUServer"=http://wsusserver "TargetGroupEnabled"=dword:00000001 "TargetGroup"="WINXP" "WUStatusServer"=http://wsuswerver 3) executed wuauclt /resetauthorization /detectnow 4)Synchronised and refreshed the group I am running out of ideas here. The client is running Windows XP pro, WSUS version is 3.0 and is running on Windows 2008 R2 64-bit. Please, help! Thanks! EDIT 13.IX.2012 @ 15.40 I should have also mentioned that we do have a Windows Update GPO for workstations group and that laptop is a part of that group.

  • Router(s) Issue: DNS quries sporadically fail with multiple computers hooked in

    - by bob-the-destroyer
    Basically, after anywhere from 5-60 minutes, DNS queries fail for a few minutes, then slowly begin to resolve correctly. Then the cycle repeats. This occurs only when more than one computer is on the network. All computers on the network experiences the same sporadic DNS outage at the same time. Wireless or wired, Linux or Windows, fresh OS install or old, browser or ping, same symptoms. Duplicated on 3 routers (not chained together, mind you) and 3 ISP's and 3 separate locations over the past several months. The only common theme is a single 5-yo WIN XP laptop which has been in use on the network throughout all this. There also may be anywhere between 1 - 10 devices hooked up wired or wirelessly at a time. The only reprieve I have from this torture is by using any VPN to an outside source - always smooth sailing. I typically set up any router to a) use WPA2/etc security; b) MAC whitelist; c) UPNP OFF (if available); d) always update firmware when available; e) obtain DNS from ISP automatically; f) set the router to act as DHCP server for the internal network. Adjusting channels has no effect. Any ideas?

  • 3-4 old computers = general purpose cluster?

    - by TheLQ
    I have 3 old computers lying around right now running a P2 at 800 MHz(?), Intel Mobile 1.6 GHz, AMD Athlon XP 2000+ at 1.66 GHz, and (might not use this) P4 at 2.7 GHz, all with 512 MB Ram, and am considering clustering them together for fun/knowledge. They would be running an undecided version of linux, preferably ubuntu based. The issue is what I want to use it for: general computing and occasional video encoding. By general computing I mean day to day tasks. However I'm not sure if every program started by a single X session is going to exist on the same machine, defeating the purpose of such a system. Will programs be split up or exist on one machine? Second, assuming this is running 100baseT ethernet (not sure if the PCI slot itself could handle Gigabit), would the speed of having a program exist over the network be an issue? It seems that the constant asking of various things in RAM would be quite slow. And before you say "buy another computer!", that's not the point of this question. I'm asking would it be usable, not necessarily practical. And yes I know, this is going to be extreamly power consuming.

  • git repository sync between computers, when moving around?

    - by Johan
    Hi Let's say that I have a desktop pc and a laptop, and sometimes I work on the desktop and sometimes I work on the laptop. What is the easiest way to move a git repository back and forth? I want the git repositories to be identical, so that I can continue where I left of at the other computer. I would like to make sure that I have the same branches and tags on both of the computers. Thanks Johan Note: I know how to do this with SubVersion, but I'm curious on how this would work with git. If it is easier, I can use a third pc as classical server that the two pc:s can sync against. Note: Both computers are running Linux. Update: So let's try XANI:s idea with a bare git repo on a server, and the push command syntax from KingCrunch. In this example there is two clients and one server. So let's create the server part first. ssh user@server mkdir -p ~/git_test/workspace cd ~/git_test/workspace git --bare init So then from one of the other computers I try to get a copy of the repo with clone: git clone user@server:~/git_test/workspace/ Initialized empty Git repository in /home/user/git_test/repo1/workspace/.git/ warning: You appear to have cloned an empty repository. Then go into that repo and add a file: cd workspace/ echo "test1" > testfile1.txt git add testfile1.txt git commit testfile1.txt -m "Added file testfile1.txt" git push origin master Now the server is updated with testfile1.txt. Anyway, let's see if we can get this file from the other computer. mkdir -p ~/git_test/repo2 cd ~/git_test/repo2 git clone user@server:~/git_test/workspace/ cd workspace/ git pull And now we can see the testfile. At this point we can edit it with some more content and update the server again. echo "test2" >> testfile1.txt git add testfile1.txt git commit -m "Test2" git push origin master Then we go back to the first client and do a git pull to see the updated file. And now I can move back and forth between the two computers, and add a third if I like to.

  • Qt 4.x: how to implement drag-and-drop onto the desktop or into a folder?

    - by Jeremy Friesner
    Hi all, I've written a little file-transfer application written in C++ using Qt 4.x ... it logs into a server, shows the user a list of files available on the server, and lets the user upload or download files. This all works fine; you can even drag a file in from the desktop (or from an open folder), and when you drop the file icon into the server-files-list-view, the dropped file gets uploaded to the server. Now I have a request for the opposite action as well... my users would like to be able to drag a file out of the server-files-list-view and onto the desktop, or into an open folder window, and have that file get downloaded into that location. That seems like a reasonable request, but I don't know how to implement it. Is there a way for a Qt application to find out the directory corresponding to where "drop event" occurred, when the icon was dropped onto the desktop or into an open folder window? Ideally this would be a Qt-based platform-neutral mechanism, but if that doesn't exist, then platform-specific mechanisms for MacOS/X and Windows (XP or higher) would suffice. Any ideas?

  • Business Tier | client state in desktop application- way around Stateful Session Beans?

    - by arthur
    I read positive inputs on the following posts concerning client state management: Stateful EJBs in web application?, here, and here. I want to know how implement such client state management for desktop applications (Swing, AWT, SWT, and other). let's assume there are n desktop clients supposed to use some (remote) services provided on an Application Server. How to maintain a separate and permanent data state for each client , distinct from the other without have to use using stateful session Beans (SFSB) ? is that even possible on this application type ? With Webapp(Servlets / JsSF and JSP) some can avoid using SFSB by HttpSession object and/or coupling it with stateless session beans (SLSB). HttpSession object would keep information for each (Web)client separate and the SLSB would play the business logic music. But HttpSession objects aren't present on desktop application and I go stuck with only SFSB and SLSB. Knowing the problems(Concurrency, Error Handling, usw ) of SFSB, I would have not wanted to use it. What would be the other options? is there only SFSB available? Thanks in advances

  • How to create a desktop shortcut to a website with website logo as icon?

    - by Wbdvlpr
    Hi I need a solution which allows users to create a desktop shortcut to a website, preferably with website logo as shortcut icon. There are ways users can create shortcut such as drag drop favicon or right click create new shortcut etc. This works but also creates the shortcut with default IE icon on windows. I am trying to avoid this method for this icon and some other reasons. I thought of creating a website-title.URL file, and tell users to download and save file to their desktop, again this works but doesn't solve the icon problem as the website logo (.ico) has to be at local disk and at a pre-specified location [IconFile=path]. I was wondering if it is possible to create a some sort of installer or windows application which users can download from the website. Once its executed by user, it creates this .URL file on user desktop which have IconFile path pre-specified, and copy the website-logo.ico at path specified in .URL file etc. So my questions are - Is it possible to create such a solution? What programming languages can be used to achieve this? Can this installer/app be made to work on non-windows machines as well? From developments point of view how big project it is? if I have to hire a programmer to do this. Please let me know if you need more information. Thanks

  • Eclipse dissapears when minimized and will not come back (12.04 Unity)

    - by Kevin
    I have Ubuntu 12.04 x64 running Unity3d. I downloaded Eclipse from eclipse.org (not the software center) and created a desktop using gnome-desktop-item-edit. The resulting file is below, and I added it to the launcher on the left of the screen by dragging that file on. #!/usr/bin/env xdg-open [Desktop Entry] Version=1.0 Type=Application Terminal=false Icon[en_US]=/home/kevin/eclipse/icon.xpm Name[en_US]=Eclipse Exec=/home/kevin/eclipse/eclipse Name=Eclipse Icon=/home/kevin/eclipse/icon.xpm#!/usr/bin/env xdg-open However, when I minimize eclipse, eclipse disappears. There is no arrow to the left of the icon in the launcher like usual. And when I click on the launcher again, it tries to relaunch eclipse instead of bringing back the one that was minimized. Eclipse also does not show up when I alt-tab. I know it is still running because I can see it running with the system monitor. Note that Eclipse works properly until it is minimized. I have observed this behavior on two different computers now. Does anyone know how to fix it?

  • Best approach for a clinic database

    - by user18013
    As a practical assignment for the database course I'm taking I've been instructed to create a database for a local clinic, I've meet with the doctors a couple of times and discussed the information that needs to be stored in the database from personal to medical. Now I'm facing a tough decision because I've been given two choices: either to implement the database as a "local website" which only operates inside the clinic via WiFi, or to implement the front-end as a regular desktop application connecting to a shared database. Note: I've a 40 days deadline to deliver the first prototype and meet with my client. My questions are: 1- which approach should I go with given that I've more experience with desktop applications programming than web? 2- if I go with desktop front-ends what would be the best way to synchronize the database between all clients?? I've no experience and having searched for an answer a lot but came up with nothing detailed on this matter. 3- if I go with the web solution which choice would be best PHP & MySQL or ASP.NET & SQL Server or a different combination?? (given that my knowledge in both PHP & ASP.NET are nearly the same).

  • Windows Azure Emulators On Your Desktop

    - by BuckWoody
    Many people feel they have to set up a full Azure subscription online to try out and develop on Windows Azure. But you don’t have to do that right away. In fact, you can download the Windows Azure Compute Emulator – a “cloud development environment” – right on your desktop. No, it’s not for production use, and no, you won’t have other people using your system as a cloud provider, and yes, there are some differences with Production Windows Azure, but you’ll be able code, run, test, diagnose, watch, change and configure code without having any connection to the Internet at all. The best thing about this approach is that when you are ready to deploy the code you’ve been testing, a few clicks deploys it to your subscription when you make one.   So what deep-magic does it take to run such a thing right on your laptop or even a Virtual PC? Well, it’s actually not all that difficult. You simply download and install the Windows Azure SDK (you can even get a free version of Visual Studio for it to run on – you’re welcome) from here: http://msdn.microsoft.com/en-us/windowsazure/cc974146.aspx   This SDK will also install the Windows Azure Compute Emulator and the Windows Azure Storage Emulator – and then you’re all set. Right-click the icon for Visual Studio and select “Run as Administrator”:    Now open a new “Cloud” type of project:   Add your Web and Worker Roles that you want to code:   And when you’re done with your design, press F5 to start the desktop version of Azure:   Want to learn more about what’s happening underneath? Right-click the tray icon with the Azure logo, and select the two emulators to see what they are doing:          In the configuration files, you’ll see a “Use Development Storage” setting. You can call the BLOB, Table or Queue storage and it will all run on your desktop. When you’re ready to deploy everything to Windows Azure, you simply change the configuration settings and add the storage keys and so on that you need.   Want to learn more about all this?   Overview of the Windows Azure Compute Emulator: http://msdn.microsoft.com/en-us/library/gg432968.aspx Overview of the Windows Azure Storage Emulator: http://msdn.microsoft.com/en-us/library/gg432983.aspx January 2011 Training Kit: http://www.microsoft.com/downloads/en/details.aspx?FamilyID=413E88F8-5966-4A83-B309-53B7B77EDF78&displaylang=en

    - by Asian Angel
    Are you tired of the same old wallpaper on your Ubuntu desktop? Now you can go from blah to literally spacious, real-time styled views of Earth with the xplanetFX Wallpaper App for Linux. You can conveniently access the “file type” downloads, screenshots, and jump-to links all on the front page. For our example we downloaded the .deb setup file on our system. The setup file will need to download three additional files to complete the setup process. After those are downloaded all dependencies will have been met and you can complete the installation process. Once that is done you can find xplanetFX by going to the Accessories Section of your Ubuntu Menu. This is what the main control window looks like when you start xplanetFX for the first time. You should take a few moments to look through the various tabs and tweak the settings for items like location, screen resolution, timing, auto-start, etc. When you are done click on Execute and within a few moments your desktop will have a fresh new look! Note: It took ~30 seconds for the display to activate on our system. Have fun with xplanetFX! xplanetFX Homepage [via OMG!

  • I'm stuck on User Defined Session destop environment

    - by Dan
    I just installed Ubuntu for the first time dual boot so I get to choose Ubuntu or windows. I then changed the setting where is doesn't ask for my password when booting up. I then installed Edubuntu desktop package. I then hit system and logged out that way i could be at the loggin screen that also lets you select the desktop environment. Edubuntu was not there but User defined session was so i clicked that thinking that might be Edubuntu and logged in. Now im totally stuck. Only walpaper on the screen as i realize now that is normal for user defined session but there is no log out button to change desktop environments now and since I set it to not ask for password at boot up there is no option to change it at start up. If i hit ctrl+alt+del it only lets you shutdown, restart, suspend, or hybernate.... no logg out. I have hit every key on the keybourd hoping something will pop up. I thought this must be a simple noob mistake that there must be endless artiles about this so did searches on google and forums and was shocked to find nothing about this. My next step unless someone can help is to uninstall and reinstall.

  • 11.10 desktop alerts (volume change and terminal bell) stopped working but all other audio still works

    - by FlabbergastedPickle
    All, My sound works just fine in 11.10 64-bit install on HP dm1-4050 Sandy Bridge notebook (e.g. audio works in Banshee, flash, games, browser, Thunderbird email notification, etc.), but the core desktop notifications (e.g. pressing a tab in a terminal where there is more than one option should trigger a terminal bell, or changing volume using volume keys should be accompanied with the supporting "quack" that the volume app makes) do not work. I've intentionally disabled login sound as explained here on ask ubuntu but even enabling it back makes no difference. These notifications did work before just fine and I am not sure when did the actually stop working but it must've been fairly recently. Only things I did were trying to install some ppa edge xorg drivers for my intel card (a separate issue) but also reverted them all with ppa-purge once I discovered they did not improve anything. Other thing I did was check volume settings with alsamixer and did alsactl store for the soundcard after I did some experimenting with volume settings for PCM (on my laptop PCM at 100% crackles so I had to lower it and make pulseaudio ignore its setting as per ask ubuntu's page). That said, neither of these should have any bearing on the said notifications since the volume is up and they clearly work everywhere else but the core desktop events. The system ready drum sound when Ubuntu boots and user reaches the login screen also does not work. The guest login behaves exactly same as mine. Audio works (including the login sound since I've not disabled it for the guest account), but no quacks when changing the volume or terminal bell sounds... I've tried copying ubuntu sounds to /usr/share/sounds/ as suggested on ask ubuntu and that did not work. I also tried using dconf-editor to check sound theme settings and tried both freedesktop (which is what it was set to) and ubuntu, as suggested on ask ubuntu. This did not work either. I tried purging the ~/.pulse folder and the /tmp/*pulse* entries, rebooting and restarting pulseaudio with -D flag. While audio came back on and behaved just fine in all aspects (e.g. one can adjust volume levels, play music, games, in-browser sound stuff, and other app alerts) except for the system ready drum sound (at the login screen), and any system event (terminal bell and volume change quack sound). It is interesting that the quack sound works inside system settings-sound when adjusting levels there, but it does not when volume is changed via top bar's volume settings... I do recall that at one point yesterday when I was restarting pulseaudio the quacks that accompany volume change did start working but I have no idea what caused that. This was also when I first realized those alerts were not working. After rebooting it was again gone. I did compile my own 3.0.14-rt31 kernel a little while ago as instructed on one of the wiki's for the 11.10 rt kernel. Everything works as before except for the said sound alerts. I am not sure if this began happening since I started using the rt kernel though and yesterday's momentary ability to hear those quacks while changing the volume make me believe that the kernel is not one responsible for this problem. One more thing I can think of is that I used alsoft-conf tool to configure buffering on the OpenAL (due to TA Spring's choppy audio) and changed in there default audio device to ALSA. I also tried reverting it to Pulseaudio as the only allowed output but the bottom part of the Backend tab always reverts to ALSA even when I select Pulseaudio. The pulseaudio does remain as the only active choice on top. This, however, once again does not make any sense in terms of preventing desktop audio alerts when everything else including OpenAL games plays sound just fine... So, there you have it, as verbose as I could make it :-). I tried all I could find on this issue and had no luck so far... Any ideas?

  • After login I only get a terminal window

    - by Ambidex
    First of, let me tell you I'm a n00b at ubuntu. I have updated my Ubuntu mediacenter to a later version of ubuntu, currently at 12.04. I'm working through a lot of updates to get to the latest. But since my first update I got the new login screen (lightdm?) and my autologin wasen't working anymore. So I Googled how I could make lightdm autologin. I've managed this by making my /etc/lightdm/lightdm.conf look as follows: [SeatDefaults] greeter-session=unity-greeter user-session=ubuntu autologin-user=my_user autologin-userutologin-user=-timeout=0 Which seemed to work... But now that it automatically logs in, I seem to get the following type of screen (through nomachine remote desktop client): Sorry... I am unable to post my screenshot here because I do not have the 10 reputation points in askubuntu yet.... darn it... But the screen has a terminal at the top left of the screen (not an actual "window"), and the ubuntu loading screen is still behind it. I've tried running startx as you can see. But, this seems to actually be x server. But if I run unity --reset, it seems that a lot of the desktop gets restored, but... with a lot of errors and warnings and the next time I boot, it's the same story all over again. Also, when I close the terminal window after getting my desktop back, I get thrown back at the login screen. Please bear with my lack of knowledge of ubuntu and it's underlying unix. I thank you in advance.

    I have what some might consider a trivial use for VNC, but I'd like to get it to work and it's technically interesting to me. My use case is that I'd like sometimes to be able to control my desktop from my living room while watching tv. The desktop runs Ubuntu, currently 12.04, but that may change soon. I'm using the default Vino server. I'd like to control it from my IPad and I have a nicely performing WiFi. I got the well-regarded (if reviews can be believed) app Vnc Viewer for the iPad. It's not working as well as I'd hoped. The problem is the speed of repainting. It's abysmally slow. I can click a close button, walk over to the desktop and see that the window has closed, but on the iPad, the VNC Client won't show the close for minutes if ever. I've noticed that CLOSING windows takes a lot longer to update than to open them. So the question is is this primarily client or server-caused? And if server-caused what can be done about it? Is Vino the best client or is something else better? Thanks

  • Problems after installing a plethora of updates

    - by box
    yesterday I decided to install 32-bit Ubuntu on my 64-bit desktop, first of all, is that a problem? After installing, i had around 270 updates to install, according to the update manager. I was having trouble launching a game with WINE, so I thought updating might help. After updating, I restarted my computer, and after a long while it showed me my desktop and the icon's on it, but I didn't get anything else. I didn't have the "taskbar" (not sure what it's called, sue me) on the left side, nor the bar at the top. I also received an error message saying some program had stopped working. I decided to restart my computer again, and that was when it told me that i have to re-configure my drivers, or run in "Low Graphics" mode for one session, amongst other options. Well, I decided to try to revert to the "basic video drivers", which was an option it gave. Restarting the computer gave me the same problem as in the second paragraph. After a few more restarts and a night of restless sleep, here I am trying to start my computer again, only to receive a black screen, and my monitor "going to sleep". I'm sort of stumped here, being new to Ubuntu (desktop, at least) and I really hope this gets fixed without me having to install Ubuntu on yet another partition (I have three other partitions for various things already) tl;dr: Black screen on boot after installing updates.

  • "Network is unreachable" When pinging google, can connect to internal computers on debian VM

    - by musher
    Similar to this SU question: "Network is unreachable" when attempting to ping google, but internal addresses work Actually, it's pretty much the same base issue. I went through that thread trying to find a solution, I changed my resolv.conf: before: domain [my work domain] search [my work domain] nameserver [my gateway] nameserver [my gateway2] I changed it to: after: domain [my work domain] search [my work domain] nameserver 8.8.8.8 nameserver 8.8.4.4 However, any time I reboot the computer the resolv.conf gets overwritten to the previous version (the 'before' above). The issues began after I installed virtualbox additions, X server and (specifically) LXDE: Cat of apt history.log: Start-Date: 2014-08-21 10:03:42 Commandline: apt-get install virtualbox-guest-utils virtualbox-guest-dkms Install: x11-xkb-utils:amd64 (7.7+1, automatic), libxaw7:amd64 (1.0.12-2, automatic), xfonts-utils:$ End-Date: 2014-08-21 10:03:56 Start-Date: 2014-08-21 10:18:39 Commandline: apt-get install lxde Install: desktop-base:amd64 (7.0.3, automatic), libgoa-1.0-0b:amd64 (3.12.4-1, automatic), lxmenu-d$ End-Date: 2014-08-21 10:21:52 Start-Date: 2014-08-21 10:26:40 Commandline: apt-get upgrade Upgrade: libio-socket-ssl-perl:am ifconfig on the guest: root@Peridot:~# ifconfig eth0 Link encap:Ethernet HWaddr 08:00:27:89:c9:20 og inet addr:172.31.2.102 Bcast:172.31.2.255 Mask:255.255.255.0 inet6 addr: fe80::a00:27ff:fe89:c920/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:2281 errors:0 dropped:1 overruns:0 frame:0 TX packets:463 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:266507 (260.2 KiB) TX bytes:120554 (117.7 KiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:4 errors:0 dropped:0 overruns:0 frame:0 TX packets:4 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:240 (240.0 B) TX bytes:240 (240.0 B) The adapter in VBox is a bridged adapter directly onto my ethernet connection; as are my other 2 VMs (which work) Other SU questions I've tried: "connect: Network is unreachable" in VirtualBox VM

  • How do I install only the KDE desktop (and not apps) on Unity?

    - by Gaba_p
    My question is pretty simple. I have Ubuntu 12.04 with Unity and I want to login with KDE. I have seen recommendations to: 1- run the three commands: $ sudo add-apt-repository ppa:kubuntu-ppa/backports $ sudo apt-get update $ sudo apt-get install kubuntu-desktop 2- run just the command: $ sudo apt-get install kubuntu-desktop 3- run the command: $ sudo apt-get install kde-standard 4- run the command: $ sudo apt-get install kde-full 5- run the command: $ sudo apt-get install plasma-desktop 6- run the command: $ sudo apt-get install kde-plasma-desktop 7- etc ... This question is very related to this one, but the answer there is not clear enough to me. There seems to be quite a number of quasi-identical commands one could use to install the KDE desktop. I just want the desktop, no KDE apps since I'll just use the ones I'm already using in Unity. Of course I also want the needed repositories added so the KDE desktop will be kept updated. How would I go about doing that?

  • Dangers of Running Computers w/o Air Conditioning

    - by Daniel Bingham
    I recently moved in to an apartment with out air conditioning. This is fine most of the time as I am in upstate New York. It only ever gets above the high 70s during the hottest of the summer months. And when it does, I'm stubborn enough that I'll just deal with wearing minimal clothing around the house. However, I'm worried about my computers. I'm a software developer and gamer, so many of my machines are very high powered. And at least one of them is a server that must be left on 24/7 (not just a game server - also serves multiple websites). I've never before had to worry about the heat too much, as I always lived in buildings with central air. The in building temperature rarely got much above 70 F. All of the machines I built had good enough air cooling that I never saw a problem. Now the temperature in building is pushing 100F and I'm worried that the machines will not be able to keep themselves cool enough by simply blowing already hot air over themselves. The hottest of them I've turned off. However, the server I cannot. It's an old Dell (not custom build) that runs on a Pentium 4 (2.2GHz). It only has a single hard drive, integrated video. And it'd not running any processor intensive servers. Just basic LAMP. It used to run a MUD server, but that's off for now. So it should be idling most of the time. I haven't been able to find any sort of built in temperature sensors in the hardware... at least not any that the programs I've found in the Debian repository can read. And it's an inherited machine to which I do not have the full specs, so I don't know the tolerances anyway. How worried should I be about it melting down on me? How worried should I be about the hard drive melting or becoming corrupted? To generalize the question for other people, what are the safe temperature tolerances for most machines. How widely does it vary, and how does one go about determining when their machine is running too hot and needs to be shut down?

  • WiFi AdHoc Network: Unable to access peer by ip

    - by Pranav
    I've set up a WiFi AdHoc network in Maverick and selected the IPv4 settings as "Shared to other computers". On the client computer, I joined the network with the same SSID and set IPv4 method to Manual and I gave it an IP 10.42.43.2 (As on the first computer, the auto generated IP was 10.42.43.1). From either of the computers, I'm not able to access the other using the IP (in browser). Any idea why? (If I browse to 10.42.43.1 from the first computer, it works) Thanks!
