• Desktop appliciations are unable to launch my browser in Windows 8

  - by Chevex

  I have a fresh copy of Windows 8 Pro installed from MSDN. I have Google Chrome installed (stable channel) and it is set as my default browser. I even went into Control Panel Default Programs to ensure that Chrome had all its defaults. When other desktop applications try to launch my browser they always fail. For example, while trying to install the Android SDK for Windows the installer accurately detected that I did not have the JDK installed. It provides a friendly button to visit java.oracle.com. When pressing this button, nothing happens at all. You can see that here: http://youtu.be/XXL8GhuWWg0 If it were only that application that was having issues I wouldn't think anything of it but I have been encountering similar issues all over the place. Probably the most irritating one is when visual studio has updates; clicking the update button does nothing. http://www.youtube.com/watch?v=zwd1mn3TId0 You can see in that screencast that Visual Studio is not able to launch the browser no matter what I click. The update button doesn't do anything and neither do the two links in the update's description. Any suggestions? I'm assuming it's a Windows issue since it is happening in multiple applications. UPDATE: Setting IE as the default browser fixes the issue. So it has something to do with it not being able to launch Chrome programmatically. Is it even possible to workaround this bug or do I have to suffer with IE as default for now?

• Two internet connections at once in Windows 7

  - by webmasters

  I have a 3G wireless modem and I have a LAN - Right now they are both connected. I need a way to choose which applications will use the 3G connection and which applications will use the LAN. My Operating System is windows 7. How can I do this? Any ideas? Here is a route print: - the 3G modem's IP is 10.81.132.96 Lets say, for example, map google.com to using the 3G internet connection.

• Nginx proxy upstream cached?

  - by Julian H. Lam

  Attempting to resolve an issue that's been annoying me for a bit. I've distilled the symptoms into a set of reproducible steps: I have two sites, siteA, and siteB. They are both Node.js applications running on different ports (for the sake of example, 4567 and 4568) Both applications have their own file in sites_available (plus a symlink from sites_enabled), which contain the directives proxy_pass http://node_siteA/ and proxy_pass http://node_siteB/ respectively, inside of a location block. They also each have an upstream block (defined globally?): upstream node_siteA { upstream node_siteB { server 127.0.0.1:4567; server 127.0.0.1:4568; } } Site A and Site B have nothing to do with each other. Yes, I am restarting (reloading, actually) nginx every time I make a change. If I take down site B and attempt to access it via the web, I am served site A. Why is this? Thoughts Other times, when I create a new Site C, for example, nginx refuses to show me anything except "Welcome to nginx!" for ~5 minutes. This suggests a resolver timeout, perhaps? When I access Site B after its config has been deleted, and it sends me to Site A, this sounds like nginx sending me to servers in a round-robin fashion...

• Win7 Hangs During App Install/Upgrade/Uninstall

  - by JadeMason

  I have a custom built PC that intermittently hangs when installing, uninstalling, or upgrading applications. Technical Specs ASUS P5E w/ WiFi Motherboard Intel Core2 Quad Q6600 Processor 4x 2GB G.Skill DDR2 800 SDRAM ASUS EAH2900XT / Radeon HD 2900XT 512MB Video Card Under normal operation the machine runs reliably, even under heavy load, such as video transcoding. The temperature never gets anywhere near where I would worry about it. However, the machine regularly hangs (complete lockup, no response to keyboard or mouse, no activity on-screen) when either installing a new application, uninstalling an existing application, or applying patches to existing applications or the OS. This is extremely frustrating as this machine is primarily used as a HTPC. Several apps are configured for automatic updates, and these updates sometimes cause the machine to lockup while we are watching content on the PC. In previously investigating this issue, I found one likely problem could be my Logitech Webcam. The Logitech software has a bug that leaves an entry in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\ Control\SessionManager\PendingFileRenameOperations Which references the Temp directory. My registry contained this error, so I uninstalled the webcam software and deleted this registry key value. Unfortunately, the machine will still intermittently hang. I've noticed that the hangs always happen when an install/upgrade/uninstall requires elevated privileges (presumably to modify the registry). I can typically get at least one install/upgrade/uninstall to complete after a reboot, but after that it is a game of russian roulette to see if the operation will succeed or hang the machine. The event log is not helpful, as log messages end at the time of the hang, with no record of a warning or error. My only recourse when the machine hangs in this way is to perform a hard reset/power cycle. Any tips on how to further debug this issue are greatly appreciated.

• Vista: window focus problem

  - by GateKiller

  Sorry for the vague title but this one is hard to explain so bear with me please. I'm using Windows Vista at work for web development and sometimes when I Click or Alt-Tab to background window, the window will get focus but it will not be brought to the front. In order to bring the window to the front, I have to click on the applications border (when the resize cursor appears) and the window will then jump to the front. I've had this problem for about a year now and it happens at least a dozen times a day, but it doesn't do this all the time - seems random. I hope I have explained the issue fully (and you've understood it) and would appreciate any constructive answers or comments to solve this problem. Example: If I Alt-Tab from Google Chrome to Notepad and this problem randomly occurs, Google Chrome will remain in front of Notepad, however, I will be able to type text into Notepad while the window is behind Google Chrome. Clicking on Notepad's content area will not bring it to the front but clicking it's window border will. Video Exampe http://vimeo.com/19388998 In this video, I clicked from Google Chome to UltraEdit and chrome stayed in font, but as you can see, I can still type in UltraEdit. I'm starting to believe that this could be a bug in Google Chrome so I'll continue to watch if this between other applications.

• IIS 6 Denies access to the default document

  - by Jim

  I've got Windows Server 2k3 with IIS6 hosting a couple ASP.NET MVC 2 applications (.NET 4), all in the Default Web Site. Most of them simply use Integrated authentication, but a couple use forms as well. All the applications work properly and are correctly accessible. The problem I'm trying to resolve is access to the default document. It is currently specified as index.htm. Both index.htm and the Default Web Site are configured to allow anonymous access (with none of the authenticated acces boxes checked). However, access is denied to the file. Accessing via server.domain.tld/ and server.domain.tld/index.htm both yield 401 errors. However, server.domain.tld/default.htm (file does not exist) properly returns a 404. If I alter the file security on index.htm to allow integrated authentication, then requesting /index.htm directly works properly for users with domain accounts, but anonymous users get a login prompt/401. How can I configure IIS to allow all users to view index.htm via server.domain.tld/?

• Loading the preview function of AUCTeX 11.86 on macports Emacs-app 23.2.1 port.

  - by Sarah

  I've installed Emacs-app 23.2.1 via MacPorts and I'm trying to install AUCTeX 11.86 so that it will work on this installation. I've run the following configure line for AUCTeX and that seems to work. ./configure --with-emacs=/Applications/MacPorts/Emacs.app/Contents/MacOS/Emacs --with-lispdir=/Applications/MacPorts/Emacs.app/Contents/Resources/site-lisp/ --with-texmf-dir=/usr/local/texlive/2010basic/texmf-local/ make and make install seem to work, and I've added the following line to my init.el (require 'tex-site) as per the installation instructions. However, when I open a TeX file, the Preview menu does not show up (although the LaTeX menu does.) The following are some of my tests: M-x load-library RET preview-latex RET doesn't seem to do anything. M-x load-library RET preview RET brings up the Preview menu. Is it safe to somehow add the load-library preview to my init.el? Or do I risk mucking up something? I'm new to Emacs and primarily trying to learn it because of the AUCTeX preview features, but I don't feel very safe in this environment yet.

• How to use LVM on Rackspace Cloud

  - by batrick

  Dear all, I am trying to set up a simple but effective solution to make a backup of my rackspace cloud servers. These servers each run subversion, trac, and some database-backed custom php applications. My idea is to set up a LVM and mount a volume under, say, /srv. In this volume, I keep the data from all applications. Instead of caring about how to back-up each app in a different way (svn hotcopy, trac-admin hotcopy, huge mess for mysql), I simply take an LVM snapshot and back this one up cloud files using the excellent cloudcity script (http://github.com/jspringman/cloudcity/blob/master/cloudcity). The advantage of this solution is that it is quick and easy, and LVM allows to make decent backups. As more apps are added, it should not be required to change the backup script much. The downside, and main point of my question here, is that I am not sure how to get LVM working on Rackspace cloud, because there is only one root volume and no service like Amazon's EBS. I was thinking it may be possible to create a large empty file and use this as a "physical volume". Has anybody done anything like this before? Or do you know why it can never work? It would be great to hear from you. Thanks, batrick

• How do I get rid of these "There is a problem with your tablet driver" messages?

  - by Adam Rosenfield

  Every time I run certain applications (including but not limited to GIMP, Microsoft Visual Studio, and 3DS Max), I get the following message box: There is a problem with your tablet driver. Please reboot your system. If the problem persists reinstall or update the driver. Obviously I've tried rebooting and that hasn't fixed anything. Secondly, I'm not running a tablet PC. This is just Windows XP SP3 running on a Dell Precision PWS490 desktop workstation. How do I get rid of these error messages? The applications still load normally after dismissing them, but they're rather annoying. Using Process Explorer, I got the call stack from the message box. It's coming from wintab32.dll. Here's the call stack when running GIMP (irrelevant frames omitted): ... 8 USER32.dll!MessageBoxA+0x45 9 wintab32.dll!WTMgrPacketHookExA+0x44a 10 libgdk-win32-2.0-0.dll!gdk_display_list_devices+0x37 ... So, does anyone know how I can get an updated version of wintab32.dll or have any other ideas? I've been keeping my system up to date with Windows Updates. The timestamp on wintab32.dll is 2007-03-30 17:38, and its MD5 sum is ffdc332007c9dc6dd346c8ac2b09a015.

• Separate Certificate by Subdomain (With multiple IPs)

  - by Brian

  Note: Yes, I realize this problem is easier to solve by just using 1 multi-domain or wildcard certificate. I wish to have an ASP.NET site running on IIS with 2 SSL domains sharing 1 web application but using separate certificates. Assuming I have 2 certificates, this can be solved on IIS7 as follows: Web Application1: Binding 1: http, 80, IP Address *, Host Name * Binding 2: https, 443, IPADDRESS1, using CERTDOMAIN1 (DOMAIN1 resolves to IPADDRESS1) Binding 3: https, 443, IPADDRESS2, using CERTDOMAIN2 (DOMAIN2 resolves to IPADDRESS2) That is to say, 2 certificates and 2 ip addresses, but both mapped to the same web application. In IIS6, the closest I have been able to come to this configuration is: Web Application1: Binding 1: http, 80, IPADDRESS1 Binding 2: https, 443, IPADDRESS1, using CERTDOMAIN1 (DOMAIN1 resolves to IPADDRESS1) Web Application2: Binding 1: http, 80, IPADDRESS2 Binding 2: https, 443, IPADDRESS2, using CERTDOMAIN2 (DOMAIN2 resolves to IPADDRESS2) That is to say, 2 certificates and 2 IP addresses, 2 web applications, both mapped to the same file location. The IIS6 solution is not optimal. Even if sharing an application pool, there are still costs associated with running the same site as two applications. Is upgrading from IIS6 to IIS7 a legitimate way to resolve this problem? Is there an IIS6 way to map 2 IP addresses within the same web application to different certificates?

• Would a PHP application benefit from being served from a RAM drive?

  - by Tom Marthenal

  I am in charge of hosting a PHP application that is large and slow, but easy to scale. The application is entirely static, with writable disk storage needed. We've profiled the application, and the main bottleneck appears to come from loading the application and not the work the application does. The application is not CPU-intensive, although it does use a fair amount of memory (think Magento). Currently we distribute it by having a series of servers with the same PHP files on their hard drive and a load balancer in front of them. Easy but expensive. I've been reading about RAM disks and the IO benefits they offer, and was wondering if they would be well-suited to PHP applications. Since PHP applications are loaded from disk for every request and often involve lots of different files (as opposed to being kept in memory like with a Java application), I would figure that disk performance can be a severe bottleneck. Would placing the PHP files on a RAM disk and using the mount point as Apache's document root offer performance benefits? A startup script could create the RAM drive and then copy the files (which are plain-text and small) from a permanent location to the temporary RAM drive. Does this make sense, or should I just trust the linux kernel to cache the appropriate files in memory by itself?

• As an admin, what tools do you use to log what you do to your boxes?

  - by Jerry

  I am more of a linux applications developer than an admin. Over time, I've built servers and maintained them, sometimes to offer services, mostly just to develop the applications I work on. Way back when I would create a file in my account to keep notes on what I did on each machine, so that I could replicate that when I migrated to other machines. Nowadays, I install something a private trac installation, install it's blog plugin, and then use that to make notes of everything I install, and most commands that I run, as well as the output. This provides me a combination wiki and blog that I find very useful as a "captain's log". I do this mostly so that when I migrate to a new clean machine, I have a much easier time in bringing it up. And yet, I am always amazed when I see others just install this, delete that, run this, setup this config, ... without seeming to use any way to actually note what they are doing. What do YOU do, and what tools are available? I am especially interested in the transition between maintaining a few machines for a few people and maintaining several to dozens of machines providing a real service. What are the best practices, and where can I find good resources? Thanks!

• How do I configure IIS to allow access to network resources for PHP scripts?

  - by Dereleased

  I am currently working on a PHP front-end that joins together a series of applications running on separate servers; many of these applications generate files that I need access to, but these files (for various reasons) reside on their parent servers. If I, from the command line, issue a bit of script such as: <?php var_dump(glob("\\\\machine-name\\some\\share\\*")); I will get the full contents of that directory, proving that there's no problem programmatically with PHP reading the contents of a UNC share. However, if I try to execute the same script from the web server, I get an empty array -- more specifically, if I use more explicitly functions designed to "open" a directory like it was a file, I get access errors. I believe this to be a permissions issue, but I am not a server/network administrator type, so I'm not sure what I need to do to correct this and get my script running, and the links I've checked out have not been a terrible amount of help, perhaps due to my background, or lack thereof as far as IIS is concerned, coupled with the fact that we are not actually using .NET for this. Relevant Stats: Windows Server 2008 Standard SP2 IIS 7.0 PHP 5.2.9 I will be connecting to two types of servers: a few other nearly-identical Server 2008 machines, and a machine running embedded XP. Links that have not been particularly helpful but maybe I am just misreading: http://support.microsoft.com/?id=306158 http://support.microsoft.com/kb/207671/EN-US/ http://support.microsoft.com/kb/280383/

• Remote offscreen rendering

  - by redmoskito

  My research lab recently added a server that has a beefy NVIDIA graphics card, which we would like to use to do scientific computations. Since it isn't a workstation, we'll have to run our jobs remotely, over an ssh connection. Most of our applications require doing opengl rendering to an offscreen buffer, then doing image analysis on the result in CUDA. My initial investigation suggests that X11 forwarding is a bad idea, because opengl rendering will occur on the client machine (or rather the X11 server--what a confusing naming convention!) and will suffer network bottlenecks when sending our massive textures. We will never need to display the output, so it seems like X11 forwarding shouldn't be necessary, but Opengl needs the $DISPLAY to be set to something valid or our applications won't run. I'm sure render farms exist that do this, but how is it accomplished? I think this is probably a simple X11 configuration issue, but I'm too unfamiliar with it to know where to start. We're running Ubuntu server 10.04, with no gdm, gnome, etc installed. However, xserver-xorg package is installed.

• Is my motherboard failing, or is there some other issue?

  - by ThatGuy

  So, several months ago I put together my own desktop PC. I set up a dual boot to Windows and Ubuntu. Recently, without changing any settings or installing anything new, the wifi stopped working on windows (I use a wifi adapter). It said it was connected, Network settings showed that it was working and running trouble shooting had no results. My internet still works on any other device. I found that removing the adapter from the motherboard and plugging it back in was the only thing that fixed the problem. Reinstalling the wifi drivers did not help. I purchased a new Wifi adapter, but the problem persists. More recently, I had a much more discouraging development. Sometimes, turning on the computer results in a boot loop: BIOS never starts. Instead, the monitor turns on as if it got a signal, then immediately turns off. This loops on it's own indefinitely until I hold down power, hard reset it, and try again. Sometimes it works, sometimes it doesn't. I haven't tested much on the Ubuntu side. It appears that wifi works at least some of the time, but since I've had issues just getting to BIOS I'm not confident the issue is on the software side. I've also noticed issues with some of the USB ports no longer working, but that seems to be off and on. Finally, as of a few minutes ago, I booted to windows to discover that everything was running very slowly. Slow here is a relative word, but I have a Samsung 840 pro SSD and I'm used to applications running nigh instantly, and it was a solid 3 minutes before any of my applications would load. Anyway, my question is this: Is it likely that my motherboard is failing? Either way, what steps can I take to try and pin down the problem and figure out what to do?

• How to track things that SHOULD happen, but might not have

  - by Kamiel Wanrooij

  I am running into a couple of issues with some applications we've deployed and maintain. I have the feeling we have approached this with some anti-patterns up to now, but I would like to see how to make this more flexible and stable. In one situation, we have a server at a client which pushes data to us to parse every night (yes, Windows Task Scheduler). This is highly unstable however, so once every month this doesn't happen because of reasons out of our control. This heavily impacts our business since we run with stale data in that situation. In another scenario we have a lot of background job processes that should be running. We already keep them up using bluepill ( http://www.github.com/arya/bluepill ) but obviously restarts happen, both automatically and manually, and people forget things or systems mess up. What I would like to track is events that should occur or should be available. Like the existence of a process, the execution of a program, or the creation/age of a file, and track it when they don't happen or exist. We develop most things in Ruby on Rails, use NewRelic, Bluepill and Munin, and run on Ubuntu. I've been toying around with counting ps aux | grep processname | wc -l in Munin scripts, or capturing the age of a file and raising alerts over 24-26 hours, stuff like that. Is there better tooling to track things that should happen, and raise alerts if they don't? P.S. I know some things are suboptimal, like manually having to define bluepill for applications and then forgetting to do so. The same goes for the push based approach of the first application, a dedicated daemon that manages that on the client side that we control and can track its connection to us might be a much better solution.

• Application Screen Repainting Issues

  - by Jeff Sheldon

  I have this issue lately at work. It drives be nuts, and I finally stopped to ask this question. It's quite often that an application I've been running just randomly fails to repaint itself for a while, usually in the editor screen. I most often see this occurring with Expression Web, Visual Studio 2008/2010 and SQL Server Management studio. These applications are what I work in the most, so I'm not surprised to mostly see it here. But I was curious if anyone else had a solution for this. I've tried: Reboots. The screen shot below is about 10 minutes after a reboot. New Video Drivers. This machine is running a Nvidia Quadro NVS 290 video card with the latest drivers. Closing other applications, this is the only thing running right now. As far as hardware, this machine has Dual Quad-Core Xeon 2.83ghz Processors, with 10 gigs of memory, running Windows XP SP3 64bit. Any help would be great. JNK EDIT: Per comments from deleted (wrong) answer: I'm running dual monitors. Set it to single display, still occurred. Rebooted, and tried it again, and it still occurred. Switched it back to dual screen. My resolution is only 1400x900 on each.

• Touchpad scroll slow and jumpy

  - by IR

  I have a laptop with a synaptics touchpad running on win7 x64. When i use the scrolling region of the touchpad in some applications, for example in Visual Studio 2008, Notepad and Windows Media Player 12, the scroll is very slow. If i pull the edge of the touchpad slowly the program will scroll one row at a time(regardless of the number of lines-settings in the mouse configuration). If i pull the edge quickly though, the program will instantly jump like 20 rows making it way too fast. In some applications, like Firefox, the scrolling work as expected. Changing the scrollspeed-setting for the touchpad does not help. If you make it slower it doesn't do the 20-row jump but then it's horribly slow and if you try to make it faster it will do the jumps all the time. I have tried both synaptics generic drivers and the "special" drivers that HP provides but they both have the same problem (except that the generic one can't adjust the scrolling speed, even though that didn't help anyway). With windows generic drivers the scrolling region doesn't even work. Other mice i've tried with scrollwheel work as they should do.

• Does OS X support linux-like features?

  - by Xeoncross

  I have been using XP for almost a decade. Contrary to popular belief, it has served me well. In the last 4 years I don't remember ever having it crash on me. It has the most stable GUI I have ever used. However, an OS is only as good as it's GUI AND command line combined. Windows command line is awful and totally useless. So I have been using Ubuntu for a couple years and Debian on my servers. The only problem is that Gnome applications (ubuntu 6-10) constantly crash on me (Ubuntu Studio was the most unstable OS I ever used). I have high quality Gigabyte, MSI, and Asus motherboards and CPU's from old Semprons/Athlons to Celerons/Core 2 Quads. What are the odds that every PC I have ever owned can't remain stable with a linux GUI? Not to mention that Adobe CSx Suite doesn't work on linux. Anyway, I am now looking at moving to a MAC in the hope of finding a stable GUI and a feature-packed command line. Does Mac OS have an integrated command line where I can do linux-like-awesomeness like rsync, ssh, wget, crong jobs, package updates, and git without having an unstable GUI? Basically, until the linux GUI applications get a little better, is OS X what I need?

• Gnome 3 application Icons disappeared

  - by robin.koch

  I edited my main menu settings (unchecked items inside a sub menu) when it happened that the window freezed and all entries on the left side disappeared (Office, System, Settings, Games, ...). I didn't think much about it, but when I restarted my computer all application entries in my menu and my favorites (quickstart bar on the left side) where gone. When I go to activities - applications I just see the "All" entry without any items to click on. ~/.config/menu/gnome-applications.menu is an empty file and ~/.config/menu/gnome-settings.menu has the folowing content: <!DOCTYPE Menu PUBLIC '-//freedesktop//DTD Menu 1.0//EN' 'http://standards.freedesktop.org/menu-spec/menu-1.0.dtd'> <Menu> <Name>Desktop</Name> <MergeFile type="parent">/etc/xdg/menus/gnome-settings.menu</MergeFile> </Menu> I also looked into the files under /etc/xdg/menus. They look like template files without any reference to actual installed programs. I assume that due to a bug it deleted all my menu settings. Is there any way to restore at least the default menu? Or are there any other places to look for my old configuration?

• Windows 8 Communication Sound Setting not working

  I've been having a problem on my new laptop recently which is familiar but baffling the usual fixes. I'm running Windows 8 with an onboard Realtek soundcard. It's similar to the one on my older computer running Windows 7. The problem is, when I'm in Skype or Mumble, Windows changes the sound output to lower everything else automatically. I've disabled the communications sound change option on the communications tab within sound devices and checked all the applications settings to insure that they are not responsible. They aren't, and I noticed something else. When I'm in the sound properties dialog, and I switch to the microphone tab, the same audio output reduction occurs. This seems to say to me that the microphone must be responsible in some way, but seeing as I uninstalled all the drivers and installed windows drivers instead, I'm confused as to why this would be occurring. Any thoughts? EDIT: I just tried disabling the built in microphone and the sound no longer get changed. More confused now? As soon as I turn it back on, the sound gets dropped again. Incidentally, the fix for this on windows 7 was this question: Windows 7 lowers applications' volume automatically I've got my computer set that way and it doesn't work.

• How to run a restricted set of programs with Administrator privileges without giving up Admin acces (Win7 Pro)

  - by frLich

  I have a shared system, running Windows7 X64, restricted to a 'standard user' with no password. Not everyone who has access to the system has the administrator password. This works rather well, except for some applications - specially the unlock-applications for encrypted hard drives/USB flash drives. The specific ones either require Administrator access (eg. Seagate Blackarmor) or simply fail without it -- since these programs are sending raw commands to a device, this is to be expected. I would like to be able to add the hashes of these particular programs to a whitelist, and have them run as administrator without needing any prompts. Since these are by definition on removable media, I can't simply use a filename or even a path. One of the users who shares the system can be considered 'crafty', so anything which temporarily grants administrator rights to an user account is certain to cause problems. What i'd like to be able to do: 1) Create an admin account that can only run programs from a whitelist (or, failing that, from a directory) I can't find a good way to do this: As far as I can tell, SRP applies equally to ALL users? Even if I put a "Deny" token on all directories on the system, such that new directories would inherit it, it could still potentially run things from the mounted USB devices. I also don't know whether it's possible to create a new directory that DOESN'T inherit from the parent, that would lake the deny token, and provide admin access. 2) Find a lightweight service that will run these programs in its local context Windows7 seems to block cross-privilege level communication by default, and I haven't found such for windows 7. One example seems to be "sudo" (http://pages.cpsc.ucalgary.ca/~nfriess/sudo/) but because it uses a WLNOTIFY hook, it won't work under Vista nor Windows7 Non-Solutions: - RunAs: Requires administrator password! (but everyone calls it "sudo" anyway) - SuRun: From Google: "Surun uses its own Windows service that adds the user to the group of administrators during program start and removes him automatically from that group again"

• RDP with multiple monitors, display preferences get reset?

  - by Martijn Kooij

  Problem: When I connect to my pc at the office via RDP all the application windows I had previously carefully placed on either monitor 1 or 2 will be "scrambled". Either all applications show on monitor 1 and monitor 2 is empty, or they have switched 1 <- 2. Expected behaviour: When I connect I see all the application windows on exactly the same position and in the exact same size as I left them the night before. I have the exact same monitors at home as I have at work: Primary 2560x1440, Secondary 900x1440. Yesterday I tried switching the physical cables on the host machine hoping that the hardware order of the monitors was the difference. But this morning my secondary monitor was completely blank, not even the taskbar (which I had set to ONLY show on the secondary). Somewhere there must be something to help Windows understand which physical monitor is which virtual RDP monitor is which RDP "server" monitor... Are there more options than switching the cables? This one has been bothering me for a long long time now, I hope someone has a solution or workaround for me. Edit I want to use both monitors, so I have checked the "Use all monitors" setting in the RDP client. For example I leave my mail and total commander on the right monitor, and visual studio and Firefox on the left monitor. When I connect to RDP I want to see those applications on the same positions and sizes.

• How to make my Ubuntu an internet gateway for my Android phone

  - by yacine

  I want to use the internet of my school on my Android, the problem is they have a Squid proxy, and many applications on my phone don't use the proxy at all. The obvious solution is to install a transparent proxy on my Android to force all applications to connect through it. The problem is that I need to root the phone to make it work, and I don't want to do it because it's not really my phone and rooting is a little risky- Another solution, which is safer, is to make my computer run as a gateway, so I put my Ubuntu IP in the gateway parameter of the phone. I'm running a small proxy on my ubuntu (cntlm), so I redirect the Android traffic to it. I did it with "iptables" as follows: iptables -t nat -A PREROUTING -s 10.0.1.118 -p tcp -j REDIRECT --to-ports 8888 iptables -t nat -A PREROUTING -s 10.0.1.118 -p udp -j REDIRECT --to-ports 8888 10.0.1.118 is the IP of the phone, 8888 is the port of cntlm (proxy on my PC). Now, on the phone: When I enter www.google.com on the navigator I get nothing (web site not found, error message of Firefox). But, when I enter http://74.125.143.101 (IP of Google) I get an error message from the school proxy (so it worked in some way – my PC redirected the traffic of the phone to the Squid proxy). The error message is : The requested URL could not be retrieved while trying to process the request get / http/1.1 host 74.125.143.101 user-Agent ... ... I think the problem is in the "GET" header,it should be GET 74.125.143.101 HTTP/1.1. But I don't understand what's happening, and I'm a certified CCNA.
