• How To Sideload Modern Apps on Windows 8

  - by Chris Hoffman

  The average Windows 8 user can only download apps that Microsoft has approved from the Windows Store. Windows 8 offers two ways to sideload unapproved apps, which are intended for developers and businesses with internal apps. These methods cannot be used by the average geek to install unapproved apps from the web. Windows 8’s new interface takes the Apple iOS approach of forbidding unapproved software, not the Android approach of allowing all users to enable sideloading. Note: This only applies to Modern apps in the new Windows 8 interface, not on the desktop. Windows desktop applications can be installed normally. However, you can’t install any desktop applications on devices running Windows RT. Why Does 64-Bit Windows Need a Separate “Program Files (x86)” Folder?

• Why Gsettings isn't enough to reset my nautilus settings?

  - by berdario

  I'm trying to narrow down a bug (to eventually report it or give up if it'll turn out that resetting a simple setting will be enough to get rid of it) I noticed that with a brand new user the bug doesn't pop up so I tried to reset the config of my user's nautilus I renamed .config/nautilus I renamed .nautilus2 (strange name... why the 2?) and I did a gsettings reset-recursively org.gnome.nautilus strangely enough, it didn't work: I previously set up to use my home as the desktop folder, and now the key has correctly been resetted $gsettings get org.gnome.nautilus.preferences desktop-is-home-dir false and yet on my desktop I see the contents of my home folder (meaning that the settings have not been resetted) I know that with the transition to gtk3 there've been lots of changes (before I should've used gconf... but now there's dconf and gsettings), so there're quite a bit of question about nautilus... but these unfortunately now seem to be outdated

• PCManFM problems: shuts down unexpectedly, would not always start [closed]

  - by cipricus

  In Lubuntu 12.04 beta (final release in a few days). I do not remember doing something outrageous to my PCManFM but now it has has a lot of problems: "extract here" menu action wouldn't work (this problem never disappears) the program shuts without obvious reason making the desktop empty (the program can be started in run (alt-f2) but this does not alway restore the desktop) would not start sometimes from its /usr/share/applications.desktop file (or the "Aplication Launch Bar") although it starts in run (alt-f2) (the last problem is temporarily solved if the program is closed in task manager and than restarted with alt-f2) I have reinstalled it to no avail. Any ideas?

• How to Unlock Applications folder

  - by Mark Coleman

  This question relates to Ubuntu 12.04 LTS. I wish to move a folder from the desktop into the applications folder at home/usr/share/applications. When I attempt to drag the folder from the desktop to the applications folder, I get the following message: "Error moving file: Permission denied" Permission or no permission, I want to move a folder from the desktop to the above said applications folder. How do I authenticate so I can make this move? There is no opportunity to authenticate when I get the error message, only "Skip" or "Cancel". I don't want to skip or cancel, I want to authenticate and move the folder. How do I do this? Thank you!

• How to copy the file from source to destination only once at a time?

  - by Viswa

  I have to copy the file from my desktop to my mounted directory. I was using the following command to copy the file from my desktop to mounted directory. os.system("cp -f /home/Desktop/filename /media/folder_1"). It works fine. But the problem is while copying the file from my source to mounted directory(folder_1) if any interruption is happens like network down, then the system continuously keep on trying. It couldn't skip that process. Finally, when the network comes the files are again copy to my mounted directory. Due to this continuous trying, next time i try to move the content it throws "permission denied" error. How do i copy the file only once, if any network issues happen then it will not keep try to copy, instead of that, it throws the error. If you know, Let me. Its very useful to me.

• Video Bug in Ubuntu 12.10 MSI CX623 laptop

  - by user104731

  http://www.youtube.com/watch?v=5xyJkS8XjgA&feature=youtu.be I managed to take a video with what happens on my Ubuntu 12.10 laptop when I play with the volume and hover with the mouse over the slider and when I press Ctrl + Alt + D (show Desktop/minimize all) The real bugs are those in which the panel becomes transparent on the down side, exactly above the volume slider (and not only when that slider appears, but also when brightness slider appears, and when blocking my touchpad applet appears) and when I have a maximized window, more maximized windows or a non maximized window that touches the panel, while I use Ctrl+Alt+D (show Desktop/hide all normal windows). Is there a way to solve this bug? PS: The other bugs are from Record My Desktop. I didn't have the mentioned bugs in ubuntu 12.04, but I like more the graphics in 12.10.

• How to have the game world get rendered on just a part of the screen?

  - by VictorB

  I am implementing a game on both Desktop and Android. The Desktop version will just rely on the keyboard to handle the user input on the game screen, whilst the Android one will have to have a set of buttons placed in a bar at the bottom of the game screen, using a Stage. Consequently, I am expecting the game world to take up the entire space available on the Desktop screen, whilst on Android it should expand to the entire width of the screen, and to the screen height minus the height of the buttons bar I've mentioned. What would be an appropriate approach of handling space sharing between the game world and the buttons bar? Thank you.

• Play music from computer on phone, over WiFi?

  - by wim

  Wasn't sure whether to ask on here on on android.stackexchange.com ... but I want to play music which is on my desktop machine through my phone. The music is coming from ext4 partition which I am happy to share on the LAN. It should use WiFi not bluetooth (because I hope to use the bluetooth interface for other things, simultaneously). Is it possible and what do I need to setup on the desktop (on Ubuntu 12.04) and/or my phone (galaxy nexus)? edit: Just to clarify, I want the music to be playing from the phone, not through the desktop's speakers.

• Very slow write performance on Debian 6.0 (AMD64) with DMCRYPT/LVM/RAID1

  - by jdelic

  I'm seeing very strange performance characteristics on one of my servers. This server is running a simple two-disk software-RAID1 setup with LVM spanning /dev/md0. One of the logical volumes /dev/vg0/secure is encrypted using dmcrypt with LUKS and mounted with the sync and noatimes flag. Writing to that volume is incredibly slow at 1.8 MB/s and the CPU usage stays near 0%. There are 8 crpyto/1-8 processes running (it's a Intel Quadcore CPU). I hope that someone on serverfault has seen this before :-(. uname -a 2.6.32-5-xen-amd64 #1 SMP Tue Mar 8 00:01:30 UTC 2011 x86_64 GNU/Linux Interestingly, when I read from the device I get good performance numbers: reading without encryption: $ dd if=/dev/vg0/secure of=/dev/null bs=64k count=100000 100000+0 records in 100000+0 records out 6553600000 bytes (6.6 GB) copied, 68.8951 s, 95.1 MB/s reading with encryption: $ dd if=/dev/mapper/secure of=/dev/null bs=64k count=100000 100000+0 records in 100000+0 records out 6553600000 bytes (6.6 GB) copied, 69.7116 s, 94.0 MB/s However, when I try to write to the device: $ dd if=/dev/zero of=./test bs=64k 8809+0 records in 8809+0 records out 577306624 bytes (577 MB) copied, 321.861 s, 1.8 MB/s Also, when I read I see CPU usage, when I write, the CPU stays at almost 0% usage.

• Is encryption really needed for having network security? [closed]

  - by Cawas

  I welcome better key-wording here, both on tags and title. I'm trying to conceive a free, open and secure network environment that would work anywhere, from big enterprises to small home networks of just 1 machine. I think since wireless Access Points are the most, if not only, true weak point of a Local Area Network (let's not consider every other security aspect of having internet) there would be basically two points to consider here: Having an open AP for anyone to use the internet through Leaving the whole LAN also open for guests to be able to easily read (only) files on it, and even a place to drop files on Considering these two aspects, once everything is done properly... What's the most secure option between having that, or having just an encrypted password-protected wifi? Of course "both" would seem "more secure". But it shouldn't actually be anything substantial. I've always had the feeling using any kind of the so called "wireless security" methods is actually a bad design. I'm talking mostly about encrypting and pass-phrasing (which are actually two different concepts), since I won't even consider hiding SSID and mac filtering. I understand it's a natural way of thinking. With cable networking nobody can access the network unless they have access to the physical cable, so you're "secure" in the physical way. In a way, encrypting is for wireless what building walls is for the cables. And giving pass-phrases would be adding a door with a key. So, what do you think?

• WEP/WPA/WPA2 and wifi sniffing

  - by jcea

  Hi, I know that WEP traffic can be "sniffed" by any user of the WIFI. I know that WPA/WPA2 traffic is encrypted using a different link key for each user, so they can't sniff traffic... unless they capture the initial handshake. If you are using a PSK (preshared key) schema, then you recover the link key trivially from this initial handshake. If you don't know the PSK, you can capture the handshake and try to crack the PSK by bruteforce offline. Is my understanding correct so far?. I know that WPA2 has AES mode and can use "secure" tokens like X.509 certificates and such, and it is said to be secure against sniffing because capturing the handshake doesn't help you. So, is WPA2+AES secure (so far) against sniffing, and how it actually works?. That is, how is the (random) link key negociated?. When using X.509 certificates or a (private and personal) passphrase. Do WPA/WPA2 have other sniffer-secure modes beside WPA2+AES? How is broadcast traffic managed to be received by all the WIFI users, if each has a different link key?. Thanks in advance! :).

• I want to use OpenVPN to access the web and email from China. How?

  - by gaoshan88

  My question: How do I use my already existing OpenVPN setup to enable secure, remote web surfing and email checking from open wireless hotspots? Some long winded details: I am running Ubuntu and have OpenVPN up and working fine as a server. My client machine connects fine as well. However, that just gets me a secure connection to my home network. What I want is to be able to access my VPN server and surf the web or check email securely from anywhere with an open wireless connection. I am frequently in China and having secure, unblocked access would be a boon (especially since I like to work from tea houses and coffee shops and I've already had a password sniffed and hacked once). I already know how to tunnel over SSH via a SOCKS proxy using something like: ssh -ND 8887 -p 22 [email protected] but since I have OpenVPN I figure why not try it? So... what are the steps involved in making it so I can connect to my VPN and the surf and check mail to my hearts content (slowly to be sure but at least it wold be secure). Thx!

• Changing a set-cookie header using mod_rewrite/mod_proxy

  - by olrehm

  I have a bunch of cgi scripts, which are served using HTTPS. They can only be reached on the intranet, not from the outside. They set a cookie with the attribute 'Secure', so that it can only be send via HTTPS. There is also a reverse proxy to one of these scripts, unfortunately using plain HTTP. When a response comes in from my cgi-script with a secure cookie, it is not being passed on via HTTP (after all, that is what that attribute is for). I need however, an exception to this rule. Is it possible to use mod_rewrite/mod_proxy or something similar, to change the set-cookie header in the response coming from my cgi script and remove the Secure, such that the cookie can be passed back to the user using the unsafe HTTP connection? I understand that this defeats the purpose of the Secure in the first place, but I need this as a temporary work around. I have searched the web and found how to add a set-cookie header using mod_rewrite, and I have also found how to retrieve the value of a cookie coming from the client in a cookie header. What I have not yet found is how to extract the set-cookie header received in the response of a script I am proxying for. Is that possible? How would I do that? Ole

• Computer Networks UNISA - Chap 12 &ndash; Networking Security

  - by MarkPearl

  After reading this section you should be able to Identify security risks in LANs and WANs and design security policies that minimize risks Explain how physical security contributes to network security Discuss hardware and design based security techniques Understand methods of encryption such as SSL and IPSec, that can secure data in storage and in transit Describe how popular authentication protocols such as RADIUS< TACACS,Kerberos, PAP, CHAP, and MS-CHAP function Use network operating system techniques to provide basic security Understand wireless security protocols such as WEP, WPA and 802.11i Security Audits Before spending time and money on network security, examine your networks security risks – rate and prioritize risks. Different organizations have different levels of network security requirements. Security Risks Not all security breaches result from a manipulation of network technology – there are human factors that can play a role as well. The following categories are areas of considerations… Risks associated with People Risks associated with Transmission and Hardware Risks associated with Protocols and Software Risks associated with Internet Access An effective security policy A security policy identifies your security goals, risks, levels of authority, designated security coordinator and team members, responsibilities for each team member, and responsibilities for each employee. In addition it specifies how to address security breaches. It should not state exactly which hardware, software, architecture, or protocols will be used to ensure security, nor how hardware or software will be installed and configured. A security policy must address an organizations specific risks. to understand your risks, you should conduct a security audit that identifies vulnerabilities and rates both the severity of each threat and its likelihood of occurring. Security Policy Content Security policy content should… Policies for each category of security Explain to users what they can and cannot do and how these measures protect the networks security Should define what confidential means to the organization Response Policy A security policy should provide for a planned response in the event of a security breach. The response policy should identify the members of a response team, all of whom should clearly understand the the security policy, risks, and measures in place. Some of the roles concerned could include… Dispatcher – the person on call who first notices the breach Manager – the person who coordinates the resources necessary to solve the problem Technical Support Specialist – the person who focuses on solving the problem Public relations specialist – the person who acts as the official spokesperson for the organization Physical Security An important element in network security is restricting physical access to its components. There are various techniques for this including locking doors, security people at access points etc. You should identify the following… Which rooms contain critical systems or data and must be secured Through what means might intruders gain access to these rooms How and to what extent are authorized personnel granted access to these rooms Are authentication methods such as ID cards easy to forge etc. Security in Network Design The optimal way to prevent external security breaches from affecting you LAN is not to connect your LAN to the outside world at all. The next best protection is to restrict access at every point where your LAN connects to the rest of the world. Router Access List – can be used to filter or decline access to a portion of a network for certain devices. Intrusion Detection and Prevention While denying someone access to a section of the network is good, it is better to be able to detect when an attempt has been made and notify security personnel. This can be done using IDS (intrusion detection system) software. One drawback of IDS software is it can detect false positives – i.e. an authorized person who has forgotten his password attempts to logon. Firewalls A firewall is a specialized device, or a computer installed with specialized software, that selectively filters or blocks traffic between networks. A firewall typically involves a combination of hardware and software and may reside between two interconnected private networks. The simplest form of a firewall is a packet filtering firewall, which is a router that examines the header of every packet of data it receives to determine whether that type of packet is authorized to continue to its destination or not. Firewalls can block traffic in and out of a LAN. NOS (Network Operating System) Security Regardless of the operating system, generally every network administrator can implement basic security by restricting what users are authorized to do on a network. Some of the restrictions include things related to Logons – place, time of day, total time logged in, etc Passwords – length, characters used, etc Encryption Encryption is the use of an algorithm to scramble data into a format that can be read only by reversing the algorithm. The purpose of encryption is to keep information private. Many forms of encryption exist and new ways of cracking encryption are continually being invented. The following are some categories of encryption… Key Encryption PGP (Pretty Good Privacy) SSL (Secure Sockets Layer) SSH (Secure Shell) SCP (Secure CoPy) SFTP (Secure File Transfer Protocol) IPSec (Internet Protocol Security) For a detailed explanation on each section refer to pages 596 to 604 of textbook Authentication Protocols Authentication protocols are the rules that computers follow to accomplish authentication. Several types exist and the following are some of the common authentication protocols… RADIUS and TACACS PAP (Password Authentication Protocol) CHAP and MS-CHAP EAP (Extensible Authentication Protocol) 802.1x (EAPoL) Kerberos Wireless Network Security Wireless transmissions are particularly susceptible to eavesdropping. The following are two wireless network security protocols WEP WPA

• Add Windows 7’s AeroSnap Feature to Vista and XP

  - by Asian Angel

  Are you using Windows Vista or XP and want that Windows 7 AeroSnap goodness on your own system? Then join us as we look at AeroSnap for Windows Vista and XP. Note: Requires .NET Framework 2.0 or higher (link provided at bottom of article). Setup What exactly does AeroSnap do you might ask…here is a quote directly from the website: “AeroSnap is a simple but powerful application that allows you to resize, arrange or maximize your desktop windows with just drag’n'drop. Simply drag a window to a side of your desktop to snap it or drag it to the top to maximize. When you drag it back to the last position, the last window size will be restored.” As soon as you have finished installing AeroSnap and started it for the first time the only item that will be visible is the “System Tray Icon”. Before going any further you should take a moment to view and make any desired adjustments in the “Options”. Note: AeroSnap works with multiple monitors. You may want to have AeroSnap start with Windows each time but the really nice setting to enable here is the “Snap Preview”. If you are using AeroSnap on Vista and have Aero enabled this will really be nice. The second portion may be of interest for those who would like to enable the keyboard shortcut function. One point worth noting about this screen is that the highest number of pixels from the screen’s edge that you can set AeroSnap for is 20 pixels. AeroSnap in Action AeroSnap is extremely easy to use…just grab the top of an app window and drag it to the left, right, or top of your screen. Since we installed this on Windows Vista we made certain to enable the “Snap Preview” in the “Options”.  We started off with dragging our Firefox 3.7 window towards the left…once we got close to the edge of the screen you can see that the left half of the screen temporarily “shaded over”. Note: The “Snap Preview” displays on the left and right movements but not the top movement. Releasing Firefox snapped it right into the “shaded over” part of the screen. The great thing about AeroSnap is that it is really easy to return the app window to it former size…all that you have to do is simply click on and grab the top portion of the app window. Moving Firefox towards the top of our screen and… It quickly snaps into filling the screen. One thing that we did notice is that the window did not “Maximize” as per the function for the button in the upper right corner. Dragging towards the right side now… And snap! Tucked in all nice and neat… You can minimize the app windows to the Taskbar and they will return to their previous “snap area” when “maximized” again. Conclusion If you have been wanting to add Windows 7’s AeroSnap goodness to your Vista and XP systems then you should definitely give this app a try.

  i was playing with the keychain certificates i wanted to remove them all and do it all again so that i learn how to do it. i have a simple app it worked perfectly before i started playing with the certificates so the code is fine. when i tried to compile my app to sent it to my iphone device it would give the error you see in the title. i looked at the log and here is what i see: Build Untitled of project Untitled with configuration Debug CodeSign build/Debug-iphoneos/Untitled.app cd /Users/sarmenhb/Desktop/myapp/Untitled setenv IGNORE_CODESIGN_ALLOCATE_RADAR_7181968 /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/codesign_allocate setenv PATH "/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin:/Developer/usr/bin:/usr/bin:/bin:/usr/sbin:/sbin" /usr/bin/codesign -f -s "iPhone Developer: sarm bo (2ZDTN5FTAL)" --resource-rules=/Users/sarmenhb/Desktop/myapp/Untitled/build/Debug-iphoneos/Untitled.app/ResourceRules.plist --entitlements /Users/sarmenhb/Desktop/myapp/Untitled/build/Untitled.build/Debug-iphoneos/Untitled.build/Untitled.xcent /Users/sarmenhb/Desktop/myapp/Untitled/build/Debug-iphoneos/Untitled.app iPhone Developer: sarm bo (2ZDTN5FTAL): no identity found Command /usr/bin/codesign failed with exit code 1 how do i fix this?

• Create shortcut from vb.net on Windows 7 box (64 bit)

  - by Matt

  I am trying to create a desktop shortcut from vb.net code on a Windows 7 box (64 bit). The following code works on XP, but when run on Win7 I just get a message stating the App has stopped working: Imports IWshRuntimeLibrary Dim WshShell As WshShellClass = New WshShellClass Dim MyShortcut As IWshRuntimeLibrary.IWshShortcut ' The shortcut will be created on the desktop 'Win 7 MyShortcut = CType(WshShell.CreateShortcut("C:\Users\Public\Desktop\iexplore.lnk"), IWshRuntimeLibrary.IWshShortcut) 'MyShortcut = CType(WshShell.CreateShortcut("C:\Documents and Settings\All Users\Desktop\iexplore.lnk"), IWshRuntimeLibrary.IWshShortcut) MyShortcut.TargetPath = "C:\Program Files\Internet Explorer\iexplore.exe" 'Specify target app full path MyShortcut.Description = "IE" MyShortcut.Save() Any thoughts or better ways to create a shorcut from code on a Win7 box?

• ssms cannot connect to default sql server instance without specifying port number

  - by Oliver

  I have multiple SQL Server 2005 instances on a box. From SSMS on my desktop I can connect to that box's named instances with no problem. After some recent network configuration changes, when I want to connect to the default instance from SSMS on my desktop, I have to specify the port number. Before the network changes, I did not have to specify the port number of the default instance. If I remote to any other box (including the one in question), and use that box's SSMS to connect to that default instance, success. From my desktop, and only from my desktop, I have to specify the port number. Is it a SQL Server configuration that I've missed? Is it possible something in my PC's configuration is getting in the way? Where would I look, or what could I pass on to the network folks to help them resolve this? Any help is appreciated.

• PFSense CSR Generation

  - by ErnieTheGeek

  I'm trying to figure out how to generate a CSR so I can generate and install a SSL cert. Here's a LINK to what I've what tried. Granted that post was for m0n0wall, but I figured openssl is openssl. Heres where I get stuck. When I run this: /usr/bin/openssl req -new -key mykey.key -out mycsr.csr -config /usr/local/ssl/openssl.cnf I get this: error on line -1 of /usr/local/ssl/openssl.cnf 54934:error:02001002:system library:fopen:No such file or directory:/usr/src/secure/lib/libcrypto/../../../crypto/openssl /crypto/bio/bss_file.c:122:fopen('/usr/local/ssl/openssl.cnf','rb') 54934:error:2006D080:BIO routines:BIO_new_file:no such file:/usr/src/secure/lib/libcrypto/../../../crypto/openssl/crypto/ bio/bss_file.c:125: 54934:error:0E078072:configuration file routines:DEF_LOAD:no such file:/usr/src/secure/lib/libcrypto/../../../crypto/open ssl/crypto/conf/conf_def.c:197:
