  • Set up a GUI managed stateful filtering firewall?

    - by Azendale
    What ways are there of setting up a stateful filtering* firewall whose rules can be managed by a GUI? Can GUFW do it? FireStarter? (or should that be avoided because it is supposedly no longer updated?) *By filtering, I'm mean the traffic I am setting rules up for is not destined for this computer. It is either from or to other computers on my LAN. Say, for (a simplified, hypothetical) example: I have an ethernet connection at my dorm that I have plugged into eth0. It gets an address of 192.168.1.185 and I also have 192.168.185.0/24 routed to me, so I don't have to do any NAT. I have a hub attached to my second ethernet port (eth1) with a few Windows computers and I give addresses out of my 192.168.185.0/24 block with DHCP. How can I use my Ubuntu box to block incoming connections from eth0 that are being routed to my Windows computers and let through just a few specific ports (so fellow students can't see what files my Windows boxes are sharing via SMB)?

  • Run a shell command with arguments from powershell script

    - by Mike Weerasinghe
    Hello, I need to extract and save a some tables from a remote SQL database using bcp. I would like to write a powershell script to invoke bcp for each table and save the data. So far I have this script that creates the necessary args for bcp. However I can not figure out how to pass the args to bcp. Every time I run the script it just shows the bcp help instead. This must be something really easy that I am not getting. #commands bcp database.dbo.tablename out c:\temp\users.txt -N -t, -U uname -P pwd -S <servername> $bcp_path = "C:\Program Files\Microsoft SQL Server\90\Tools\Binn\bcp.exe" $serverinfo =@{} $serverinfo.add('table','database.dbo.tablename') $serverinfo.add('uid','uname') $serverinfo.add('pwd','pwd') $serverinfo.add('server','servername') $out_path= "c:\Temp\db\" $args = "$($serverinfo['table']) out $($out_path)test.dat -N -t, -U $($serverinfo['uid']) -P $($serverinfo['pwd']) -S $($serverinfo['server'])" #this is the part I can't figure out & $bcp_path $args

  • Solving the NP-complete problem in XKCD

    - by Adam Tuttle
    The problem/comic in question: http://xkcd.com/287/ I'm not sure this is the best way to do it, but here's what I've come up with so far. I'm using CFML, but it should be readable by anyone. <cffunction name="testCombo" returntype="boolean"> <cfargument name="currentCombo" type="string" required="true" /> <cfargument name="currentTotal" type="numeric" required="true" /> <cfargument name="apps" type="array" required="true" /> <cfset var a = 0 /> <cfset var found = false /> <cfloop from="1" to="#arrayLen(arguments.apps)#" index="a"> <cfset arguments.currentCombo = listAppend(arguments.currentCombo, arguments.apps[a].name) /> <cfset arguments.currentTotal = arguments.currentTotal + arguments.apps[a].cost /> <cfif arguments.currentTotal eq 15.05> <!--- print current combo ---> <cfoutput><strong>#arguments.currentCombo# = 15.05</strong></cfoutput><br /> <cfreturn true /> <cfelseif arguments.currentTotal gt 15.05> <cfoutput>#arguments.currentCombo# > 15.05 (aborting)</cfoutput><br /> <cfreturn false /> <cfelse> <!--- less than 15.05 ---> <cfoutput>#arguments.currentCombo# < 15.05 (traversing)</cfoutput><br /> <cfset found = testCombo(arguments.currentCombo, arguments.currentTotal, arguments.apps) /> </cfif> </cfloop> </cffunction> <cfset mf = {name="Mixed Fruit", cost=2.15} /> <cfset ff = {name="French Fries", cost=2.75} /> <cfset ss = {name="side salad", cost=3.35} /> <cfset hw = {name="hot wings", cost=3.55} /> <cfset ms = {name="moz sticks", cost=4.20} /> <cfset sp = {name="sampler plate", cost=5.80} /> <cfset apps = [ mf, ff, ss, hw, ms, sp ] /> <cfloop from="1" to="6" index="b"> <cfoutput>#testCombo(apps[b].name, apps[b].cost, apps)#</cfoutput> </cfloop> The above code tells me that the only combination that adds up to $15.05 is 7 orders of Mixed Fruit, and it takes 232 executions of my testCombo function to complete. Is there a better algorithm to come to the correct solution? Did I come to the correct solution?

  • Wrapping a pure virtual method with multiple arguments with Boost.Python

  • How to set wifi driver settings to prefer 5 GHz channel above 2.4 GHz

    - by Wouter
    Currently I'm in a new building of my university. In this building my wifi often breaks down and then restores connection again. This is really irritating since it happens a lot. Now as a coincidence there were some tech guys running around here and where asking everyone if the wifi was doing fine. I told them that my wifi tears down all the time and then reconnects. They figured out that my wifi is switching all the time between the 2.4 GHz channel and 5 GHz channel. They asked me if I could acces the driver settings of my wireless card. Unfortunately I don't know how to do this is in either Linux or Windows. And unfortunately again they only knew the windows solution xD. So I hope somebody can tell me how I tell my wifi that it should stay on the 5 GHz network and not disconnect and switch to the 2.4 GHz channel?

  • Give back full control to a user on a disk from another computer

    - by Foghorn
    I have my friend's hard drive mounted externally. After messing with the permissions with TAKEOWN so I could fix some viruses, I have full control over their drive. The problem is, now it's stuck in a "autochk not found" reboot sequence. I think the problem is that the boot sector is invisible to the drive now. So my question is, How can I use icacls to give back the full ownership, when the user I am giving it to is not on my machine? I ran the TAKEOWN command from my windows 7 laptop, their machine is a windows xp Professional with three partitions, I only altered the one that has the boot sector. Here is the permissions that icacls shows: (Where my computer is %System% my username is ME, and the drive is E:\ C:\Users\ME icacls E:\* E:\$RECYCLE.BIN %System%\ME:(OI)(CI)(F) Mandatory Label\Low Mandatory Level:(OI)(CI)(IO)(NW) E:\ALLDATAW %System%\ME:(I)(OI)(CI)(F) E:\alrt_200.data %System%\ME:(OI)(CI)(F) E:\AUTOEXEC.BAT %System%\ME:(OI)(CI)(F) E:\AZ Commercial %System%\ME:(I)(OI)(CI)(F) E:\boot.ini %System%\ME:(OI)(CI)(F) E:\Config.Msi %System%\ME:(I)(OI)(CI)(F) E:\CONFIG.SYS %System%\ME:(OI)(CI)(F) E:\Documents and Settings %System%\ME:(I)(OI)(CI)(F) E:\IO.SYS %System%\ME:(OI)(CI)(F) E:\Mitchell1 %System%\ME:(I)(OI)(CI)(F) E:\MSDOS.SYS %System%\ME:(OI)(CI)(F) E:\MSOCache %System%\ME:(I)(OI)(CI)(F) E:\NTDClient.log %System%\ME:(OI)(CI)(F) E:\NTDETECT.COM %System%\ME:(OI)(CI)(F) E:\ntldr %System%\ME:(OI)(CI)(F) E:\pagefile.sys %System%\ME:(OI)(CI)(F) E:\Program Files %System%\ME:(I)(OI)(CI)(F) E:\RECYCLER %System%\ME:(I)(OI)(CI)(F) E:\RHDSetup.log %System%\ME:(OI)(CI)(F) E:\System Volume Information %System%\ME:(I)(OI)(CI)(F) E:\WINDOWS %System%\ME:(I)(OI)(CI)(F) Successfully processed 22 files; Failed processing 0 files C:\Users\ME

  • How to set default xrandr settings?

    - by echo-flow
    I'm trying to enable dual monitors in Ubuntu. This is working fine, but every time I do it, desktop effects is disabled. I think I've found the reason why, though: https://wiki.ubuntu.com/X/Config/Multihead/ As with the GNOME XRandR configuration method, setting Virtual to too large a value may result in a loss of hardware acceleration, and thus an inability to use Compiz and its desktop effects. When I use the GNOME monitor applet, or the Monitors configuration in the System menu, the default xrandr settings puts the second monitor to the right of the first, and, as I found with this bug, for most monitors this creates a virtual desktop larger than the maximum 2048 horizontal resolution needed for hardware acceleration on my netbook hardware. So, it seems like if I can modify xrandr's default settings so that it places the new desktop above or below (north or south of) the main LVDS display, then hardware acceleration, and therefore compiz will continue to work. Can anyone tell me, what is the easiest way to achieve this? UPDATE: I have confirmed that multihead support with desktop effects and hardware acceleration works when I move the external monitor display north of the main LVDS display. Right now this involves the following process: plugging in the external monitor, starting the Monitors configuration menu, desktop effects are disabled automatically (and all of the windows on my workspaces are moved to the first workspace), repositioning the external display so that it is north of LVDS display and clicking apply, and then navigating to the Appearance menu and telling it to reenable desktop effects. Is there a simpler way do this? UPDATE 2: OK, so I thought that perhaps the GNOME Monitors configuration screen was trying to be clever, and might be disbling desktop effects. So, I just tried using the xrandr command-line client instead, as follows: xrandr --output VGA1 --above LVDS1 When I do that, desktop effects are still disabled, and I need to manually reenable them. This, despite the fact that hardware acceleration works, and there is never a point where hardware acceleration stops working because the horizontal dimension of the virtual display is too large. So what program is trying to be clever, and is turning off desktop effects when it doesn't need to? And how do I make it stop? If there were a way to re-enable desktop effects from the command line, which I could then put into a script along with the proper xrandr invocation, I would accept that as a workaround. UPDATE 3: OK, here's my script to enable a second monitor with desktop effects. It might be evil, I'm not sure: second-monitor.sh xrandr --output VGA1 --above LVDS1 sleep 3 compiz --replace & The sleep statement might not be necessary. If there's a better way to do this, please let me know. UPDATE 4: This is a Dell Mini Inspiron 1012. Here are my system specifications: lspci -vv 00:02.0 VGA compatible controller: Intel Corporation N10 Family Integrated Graphics Controller Subsystem: Dell Device 041a Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx+ Status: Cap+ 66MHz- UDF- FastB2B+ ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 0 Interrupt: pin A routed to IRQ 29 Region 0: Memory at f0b00000 (32-bit, non-prefetchable) [size=512K] Region 1: I/O ports at 18d0 [size=8] Region 2: Memory at d0000000 (32-bit, prefetchable) [size=256M] Region 3: Memory at f0900000 (32-bit, non-prefetchable) [size=1M] Capabilities: <access denied> Kernel driver in use: i915 Kernel modules: i915 00:02.1 Display controller: Intel Corporation N10 Family Integrated Graphics Controller Subsystem: Dell Device 041a Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- Status: Cap+ 66MHz- UDF- FastB2B+ ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 0 Region 0: Memory at f0b80000 (32-bit, non-prefetchable) [size=512K] Capabilities: <access denied> lsmod | grep i915 i915 287458 2 drm_kms_helper 29329 1 i915 drm 162409 3 i915,drm_kms_helper intel_agp 24375 2 i915 i2c_algo_bit 5028 1 i915 video 17375 1 i915

  • Passing multiple codeblocks as arguments

    - by doctororange
    I have a method which takes a code block. def opportunity @opportunities += 1 if yield @performances +=1 end end and I call it like this: opportunity { @some_array.empty? } But how do I pass it more than one code block so that I could use yield twice, something like this: def opportunity if yield_1 @opportunities += 1 end if yield_2 @performances +=1 end end and: opportunity {@some_other_array.empty?} { @some_array.empty? } I am aware that this example could be done without yield, but it's just to illustrate. Thanks.

  • Java: Using Comman line arguments to process the names of files

    I'm a writing a program that will determine the number of lines, characters, and average word length for a text file. For the program, the specifications say that the file or files will be entered as a command line argument and that we should make a TestStatistic object for each file entered. I don't understand how to write the code for making the TestStatistic objects if the user enters more than one file.

  • Ubuntu / FileZilla FTP Set Up

    - by Dean Mark Anthony
    I have successfully installed VSFTPD and I have configured it to allow FTP connection from my Windows laptop running FileZilla. FileZilla is pointing at the directory srv/ftp on my server; the files that are stored in srv/ftp are showing in the Remote Site section of FileZilla. This indicates that it is connecting to my FTP server. What I need to do is point FileZilla toward the directory var/www so that all files that I transfer are visible on my self-hosted website. I cannot find out how to do this. Do I need to perform some updates to the vsftpd.conf file, and if so what do I change? Do I need to perform updates to my FileZilla console? I am comfortable in terms of changing .conf files, port forwarding and setting permissions etc. I just need to know what precisely needs to be changed. Much love...

  • zend_form ViewScript decorator / passing arguments

    - by timpone
    I have a form that is extend from Zend_Form. I am placing the form into a ViewScript decorator like this: $this->setDecorators(array(array('ViewScript', array('viewScript' => 'game/forms/game-management.phtml')))); I'd like to pass in a variable to this ViewScript but am not sure how this could be done. Since the partial renders out as a Zend_View (allowing $this-app_store_icon for rendering), it seems like there should be a way to pass variables to be rendered. I tried the following but to no avail. $this->setDecorators(array(array('ViewScript', array('viewScript' => 'game/forms/game-management.phtml'),array('app_store_picon'=>$current_app_store_picon)))); Any help on how to get this done would be appreciated. thanks

  • Unable to set my own icon for launcher item in 12.04

    I use the Faenza icon collection in Ubuntu 12.04 Unity with no issues. I decided to change my Gimp launcher icon, so I made my own (gimp-ak.png) and added it, and its appropriately sized derivatives, to the Faenza icon folders: /usr/share/icons/Faenza/apps/16/gimp-ak.png /usr/share/icons/Faenza/apps/22/gimp-ak.png /usr/share/icons/Faenza/apps/24/gimp-ak.png /usr/share/icons/Faenza/apps/32/gimp-ak.png /usr/share/icons/Faenza/apps/48/gimp-ak.png /usr/share/icons/Faenza/apps/64/gimp-ak.png /usr/share/icons/Faenza/apps/96/gimp-ak.png /usr/share/icons/Faenza/apps/scalable/gimp-ak.svg I then updated the Icon field in /usr/share/applications/gimp.desktop from "gimp" to "gimp-ak": [Desktop Entry] Version=1.0 Type=Application Name=GIMP Image Editor GenericName=Image Editor Comment=Create images and edit photographs Exec=gimp-2.6 %U TryExec=gimp-2.6 Icon=gimp-ak Terminal=false Categories=Graphics;2DGraphics;RasterGraphics;GTK; X-GNOME-Bugzilla-Bugzilla=GNOME X-GNOME-Bugzilla-Product=GIMP X-GNOME-Bugzilla-Component=General X-GNOME-Bugzilla-Version=2.6.12 X-GNOME-Bugzilla-OtherBinaries=gimp-2.6 StartupNotify=true MimeType=application/postscript;application/pdf;image/bmp;image/g3fax;image/gif;image/x-$ X-Ubuntu-Gettext-Domain=gimp20 After logging off (and even restarting), my custom icon does not show up - Gimp has the default gear icon: Setting the Icon field in gimp.desktop to any other icon in the Faenza collection works fine.

  • WiX - create a bootstrap that passes arguments to the msiexec

    - by Dror Helper
    I need to create a bootstrap for my WiX project I've tried using setupbld.exe but it will only allow me to create an executable that will show my UI or one that will behave as a silent installer but not both. I need to be able to run the resulting executable with argument that will tell it wether or not to show the UI during installation. I've found this post by John Robbins that explains how to re-build the setup.exe stub used in the creation of the bootstrap but I was hoping there is a simpler way to do what I need. Does anyone know of a way to create a bootstrap that I use to run either as a simple (with UI) install or as a silent install.

  • Set a Video as Your Desktop Wallpaper with VLC

    - by DigitalGeekery
    Are you tired of static desktop wallpapers and want something a bit more entertaining? Today we’ll take a look at setting a video as wallpaper in VLC media player. Download and install VLC player. You’ll find the download link below. Open VLC and select Tools > Preferences. On the Preferences windows, select the Video button on the left. Under Video Settings, select DirectX video output from the Output dropdown list. Click Save before exiting and then restart VLC. Next, select a video and begin playing it with VLC. Right-click on the screen, select Video, then DirectX Wallpaper.   You can achieve the same result by selecting Video from the Menu and clicking DirectX Wallpaper.   If you’re using Windows Aero Themes, you may get the warning message below and your theme will switch automatically to a basic theme.   After the Wallpaper is enabled, minimize VLC player and enjoy the show as you work.     When you are ready to switch back to your normal wallpaper, click Video, and then close out of VLC.   Occasionally we had to manually change our wallpaper back to normal. You can do that by right clicking on the desktop and selecting your theme.   Conclusion This might not make the most productive desktop environment, but it is pretty cool. It’s definitely not the same old boring wallpaper!

  • How to set Default Web Browser, Mail Client, Video Player & Music Player in the system

    - by Luis Alvarado
    I am trying to find the option that sets, for the whole system the default Web Browser, Mail Client, Video Player and Music Player instead of having to do it for each type of file. I knew where the option was in 11.04 but somehow I can not find it again. Just to not get anymore confused I am not talking about right clicking a file then changing the "Open With" to the one I want. The option I am looking for affects everything in general, so if I change, for example, the default video player to VLC, all movies will be watched with VLC. I am using Unity.

  • Set default browser to OPEN browser

    - by dmeu
    Hi I am switching constantly between browsers (three different at the moment). So i was also switching default browsers to open my mail / new links etc... I also saw that with the command sudo update-alternatives --config x-www-browser the browsers have different priorities. So I had the idea that it could be possible that the default browser could be the browser/s that is/are actually open and running! And if two are running, the one with higher priority is chosen. Unluckily I did not find anything.. Is this possible? Would be really great! cheers dmeu

  • Parabolic throw with set Height and range (libgdx)

    - by Tauboga
    Currently i'm working on a minigame for android where you have a rotating ball in the center of the display which jumps when touched in the direction of his current angle. I'm simply using a gravity vector and a velocity vector in this way: positionBall = positionBall.add(velocity); velocity = velocity.add(gravity); and velocity.x = (float) Math.cos(angle) * 12; /* 12 to amplify the velocity */ velocity.y = (float) Math.sin(angle) * 15; /* 15 to amplify the velocity */ That works fine. Here comes the problem: I want to make the jump look the same on all possible resolutions. The velocity needs to be scaled in a way that when the ball is thrown straight upwards it will touch the upper display border. When thrown directly left or right the range shall be exactly long enough to touch the left/right display border. Which formula(s) do I need to use and how to implement them correctly? Thanks in advance!

  • How to set acpi=off for installation?

    - by Johan Helgø
    I'm trying to install Ubuntu 12.04 LTS 64bit from a USB created in Windows using the recommended software from pendrivelinux. The USB is tested on two laptops and works fine. The install does not work on my desktop PC, it either hangs with lots of text on the screen, or it just gives me a screen with garbled colors. Right now it hangs on "[3.925311] Initializing USB Mass Storage driver...", but it hangs on different spots every time I try. I know that acpi=off will fix this. On older versions, there used to be a pink screen with the icon of a keyboard, at that screen I could press ESC, and I would then get a long list of languages, I could choose English, and then I would get options for setting acpi=off, then install without any problems. This new install menu does not have those options. The (now black and white) "Installer boot menu"'s advanced options is blank. There simply are no advanced options. If I go to help, then press F6, I get to a help screen describing the different boot parameters. I see examples of writing "Install acpi=off" However, writing "install acpi=off" it gives an error saying "could not find kernel image: install". How can I install Ubuntu 12.04 with acpi=off? (Oh, btw, nothing happens if I press F6 in the "Installer boot menu")
