  • Configure Windows firewall to prevent an application from listening on a specific port

    - by U-D13
    The issue: there are many applications struggling to listen on port 80 (Skype, Teamviewer et al.), and to many of them that even is not essential (in the sense that you can have a httpd running and blocking the http port, and the other application won't even squeak about being unable to open the port). What makes things worse, some of the apps are... Well, I suppose, that it's okay that the mentally impaired are being integrated in the society by giving them a job to do, but... Programming requires some intellectual effort, in my humble opinion... What I mean is that there is no way to configure the app not to use specific ports (that's what you get for using proprietary software) - you can either add it to windows firewall exceptions (and succumb to undesired port opening behavior) or not (and risk losing most - if not all - of the functionality). Technically, it is not impossible for the firewall to deny an application opening an incoming port even if the application is in the exception list. And if this functionality is built into the Windows firewall somewhere, there should be a way to activate it. So, what I want to know is: whether there exists such an option, and if it does how to activate it.

  • Lose internet connection, yet online games continue

    - by Mike
    For the past week or so, my internet connection has been anything but stable. Restarting my modem/router always fixes the problems, but since it has occurred so often, I'm noticing confusing patterns which I was hoping someone could help answer. My internet connection kicks out about 4-5 times a day. The sure-fire way to fix it is to restart my all-in-one modem/router. Sometimes I can diagnose the problem on my laptop which resets my wireless network adapter and fixes the problem, but not always. If that doesn't fix the problem, it usually reports that the connection between the modem and internet is the problem which requires a restart of the router. The odd thing which baffles me is that my connection is supposedly lost such that no browsers can connect to sites, yet things like online games still continue to play without issue. How is this possible? I thought maybe the game was running locally on my PC but that couldn't be the answer because I was still getting messages from other players. So my real question is: How can my internet browsers (firefox, chrome, even IE) lose connection to the internet, but other applications like online games not? Am I actually losing connection or am I mistaken? Edit: I'd also like to add that netflix on my PS3 which is directly connected to the same access point will also lose connection. So internet browsers and netflix lose their internet connection while online games continue without an issue.

  • New XPC: No video, no ethernet link, but drive spins

    - by Mike Pennington
    I bought a Shuttle XPC SH67H3 with integrated video. I installed: An Intel i5 2450P 16GB DDR3 RAM A SATA hard drive from my old linux server that still is bootable I have both power connectors plugged into the motherboard. I realize that the Intel i5-2450P doesn't have video capabilities; however, the drive spins like it's doing something useful. It seems like I should get an ethernet link light when I fire this up. I plan to run this headless anyway, so it would be really nice if I could figure out how to run this without a video card at all. I know the IP address and login info for the linux install on the disk. I plugged in speakers, but get no bios beeps when I power it up. Shuttle's bios manual has nothing in there that indicates I should have problems in this configuration. My questions: Is there a reason that the missing video card would block usage of the ethernet port? Are there settings on the motherboard / bios I can change to get this working?

  • Bash: Reset and Clear Commands

    - by sixtyfootersdude
    I have been using the command: reset to clear my terminal. Although I am pretty sure this is not what I should be doing. Reset, as the name suggests resets your entire terminal (changes lots of stuff). Here is what I want: I basically want to use the command clear. However if you clear and then scowl up you still get tones of stuff from before. In general this is not a problem however I am looking at gross logs that are long and I want to make sure that I am just viewing the most recent one. I know that I could use more or something like that but I prefer this approach.

  • Postfix on Snow Leopard unable to send MIME emails, including header contents in message body

    - by devvy
    I configured postfix on snow leopard by adding the following line to /etc/hostconfig: MAILSERVER=-YES- I then configured postfix to relay through my ISP's SMTP server. I added the following two lines in their respective places within /etc/postfix/main.cf: myhostname = 1and1.com relayhost = shawmail.vc.shawcable.net I then have a simple PHP mail function wrapper as follows: send_email("[email protected]", "[email protected]", "Test Email", "<p>This is a simple HTML email</p>"); echo "Done"; function send_email($from,$to,$subject,$message){ $header="From: <".$from."> "; $header.= 'MIME-Version: 1.0' . " "; $header.= 'Content-type: text/html; charset=iso-8859-1' . " "; $send_mail=mail($to,$subject,$message,$header); if(!$send_mail){ echo "ERROR"; } } With this, I am receiving an e-mail that appears to be improperly formatted.

  • Why is Automator crashing on launch?

    - by zbrimhall
    I've run into an odd problem where Automtor.app on Snow Leopard crashes on launch. At some point in the past, I put a copy of iPhoto.app into my public directory to copy over to another machine. Now, Automator.app won't run unless my public directory has a copy of iPhoto.app in it. If I remove it, Automator.app crashes on launch. Here's what happens: Launch Automator.app After the Automator menu bar appears, but before any windows appear, I get the dreaded beach ball for a few seconds Automator crashes Here's the output from Console.app: 12/26/09 2:11:24 PM Automator[11736] The action “Add Movie to iDVD Menu” could not be loaded because the application “iDVD” was not found. 12/26/09 2:11:24 PM Automator[11736] The action “Get iDVD Slideshow Images” could not be loaded because the application “iDVD” was not found. 12/26/09 2:11:24 PM Automator[11736] The action “Initiate Remote Broadcast” could not be loaded because the application “QuickTime Broadcaster” was not found. 12/26/09 2:11:24 PM Automator[11736] The action “New iDVD Menu” could not be loaded because the application “iDVD” was not found. 12/26/09 2:11:24 PM Automator[11736] The action “New iDVD Movie Sequence” could not be loaded because the application “iDVD” was not found. 12/26/09 2:11:24 PM Automator[11736] The action “New iDVD Slideshow” could not be loaded because the application “iDVD” was not found. 12/26/09 2:11:24 PM Automator[11736] The action “New QuickTime Slideshow” could not be loaded because the application “QuickTime Player” was not found. 12/26/09 2:11:24 PM Automator[11736] The action “Set iDVD Background Image” could not be loaded because the application “iDVD” was not found. 12/26/09 2:11:24 PM Automator[11736] The action “Set iDVD Button Face” could not be loaded because the application “iDVD” was not found. 12/26/09 2:11:24 PM Automator[11736] The action “Set Movie Annotations” could not be loaded because the application “QuickTime Player” was not found. 12/26/09 2:11:24 PM Automator[11736] The action “Set Movie Playback Properties” could not be loaded because the application “QuickTime Player” was not found. 12/26/09 2:11:24 PM Automator[11736] The action “Set Movie URL” could not be loaded because the application “QuickTime Player” was not found. 12/26/09 2:11:24 PM Automator[11736] The action “Show Main iDVD Menu” could not be loaded because the application “iDVD” was not found. 12/26/09 2:11:25 PM Automator[11736] Can not ID UTI for path The value %@ is invalid.: The file “The value %@ is invalid.” couldn’t be opened because there is no such file. 12/26/09 2:11:25 PM Automator[11736] Can not ID UTI for path /Users/brimhall/Public/iPhoto.app: The file “iPhoto.app” couldn’t be opened because there is no such file. 12/26/09 2:11:25 PM Automator[11736] Can not ID UTI for path The value %@ is invalid.: The file “The value %@ is invalid.” couldn’t be opened because there is no such file. 12/26/09 2:11:26 PM Automator[11736] -[NSAttributeDictionary length]: unrecognized selector sent to instance 0x49c770 12/26/09 2:11:26 PM Automator[11736] -[NSAttributeDictionary length]: unrecognized selector sent to instance 0x49c770 12/26/09 2:11:38 PM com.apple.launchd.peruser.501[203] ([0x0-0x2ad2ad].com.apple.Automator[11736]) Job appears to have crashed: Segmentation fault I've tried deleting my Automator.app Preferences file and Application Support directory to get it to look for iPhoto.app in the system-wide Applications directory, but to no avail.

  • Tunning scrolling in urxvt

    - by Ivan Petrushev
    Hello, I'm using rxvt-unicode version 9.06 at Ubuntu 9.10. I was used to aterm, where you can use SHIFT + up/down arrow to scroll the printed output with a line up or down. You can also use SHIFT + pgup/pgdown to scroll one screen up or down. In urxvt I can use the pgup/pgdown combination as well, but can't use the up/down arrow combination. It is very useful to be able to scroll by single lines. Do you have any idea how to enable the up/down arrow scrolling? This is my ~/.inputrc: set show-all-if-ambiguous on And this is my ~/.Xdefaults: URxvt*geometry:80x35 URxvt*transparent:true URxvt*shading:40 URxvt*saveLines:12000 URxvt*foreground:White URxvt*background:Blue URxvt*font: -*-terminus-*-*-*-*-14-*-*-*-*-*-*-* URxvt*color4:RoyalBlue URxvt*color12:RoyalBlue URxvt*scrollBar:true URxvt*scrollBar_right:false URxvt*scrollstyle:rxvt

  • usb vs firewire for connecting two RAID 0 disks

    - by Arne
    I have a 2TB and a 4TB RAID 0 external drives (both have two physical hard drives in them). Both have a FW800, FW400, and USB port. My MacBook Pro has one FW800 port and two USB ports. I want to copy data from the 4TB drive to the 2TB drive. Is it better to A - connect both directly to the laptop, one with USB and one with FW800 or B - connect the 4TB drive to laptop with FW800 and the 2TB drive to the 4TB drive using a FW400 cable? Anyone have problems daisy-chaining RAID 0 disks using FW? Thanks!

  • OSX: Howto start VirtualBox VM on startup?

    - by snies
    The Question How do i start this Wiki VM at the startup of the OSX Server? I am running OSX Server 10.6.8 and VirtualBox 4.1.8 r75467 and a Debian Linux VM (called "wiki"). . What I tried so far Following this article: http://mikkel.hoegh.org/blog/2010/12/23/run-virtualbox-boot-mac-os-x/, i have wrote this plist and placed it in /Library/LaunchDaemons/bar.foo.WikiVirtualBox.plist: <plist version="1.0"> <dict> <key>Label</key> <string>bar.foo.WikiVirtualBox</string> <key>ProgramArguments</key> <array> <string>/usr/bin/VBoxHeadless</string> <string>-s</string> <string>wiki</string> </array> <key>RunAtLoad</key> <true></true> <key>UserName</key> <string>root</string> <key>WorkingDirectory</key> <string>/var/root</string> <key>StandardErrorPath</key> <string>/var/log/bar.foo.WikiVirtualBox.stderr.log</string> <key>StandardOutPath</key> <string>/var/log/bar.foo.WikiVirtualBox.stdout.log</string> </dict> </plist> and told launchd to start it: sudo launchctl load -w /Library/LaunchDaemons/bar.foo.WikiVirtualBox.plist . The Logfile But the VM doesn't start. A Look at tail -f /var/log/system.log shows: sudo[1909]: administrator : TTY=ttys000 ; PWD=/Users/administrator ; USER=root ; COMMAND=/bin/launchctl load -w /Library/LaunchDaemons/bar.foo.WikiVirtualBox.plist VBoxSVC[1914]: 3891612: (connectAndCheck) Untrusted apps are not allowed to connect to or launch Window Server before login. VBoxSVC[1914]: kCGErrorFailure: Set a breakpoint @ CGErrorBreakpoint() to catch errors as they are logged. com.apple.launchd[1] (bar.foo.WikiVirtualBox[1910]): Exited with exit code: 1 When i log into the server via ssh (so no login window opened) i can run: /usr/bin/VBoxHeadless -s wiki and it works. So i don't understand the error above.

  • Linux DD command partition -to- partition

    - by Ben Jackson
    I just used the DD command to copy the contents of one partition over to another partition on another drive, like this: dd if=/dev/sda2 of=/dev/sdb2 bs=4096 conv=noerror sda2 partition was 66GB and sdb2 was 250GB. I read that by doing this the extra space on the drive I am copying to will be wasted, is this true? I wasn't worried about loosing the extra space for the time being however, I just ran: sudo kill -USR1 (PID) to view the current status of DD and it has written over 66GB of data, will it continue to write data until it gets to 250GB? If so, is there a way to stop the process without corrupting it as waiting for it to write blank space seems like a waste of time.

    Hi All currently having an issue where the personal folders in outlook seem to be disappearing. We have a folder called 0 Mail Filing, it seems to have disappeared, but doing a search for mail, it finds the mail and the folder is still in inbox/0 Mail Filing.

We are using Outlook 2007 with Exchange Server 2003. Thanks Jamie T

  • Windows 8 can't open any modern UI app

    - by Joyal
    I just upgraded my machine with Windows 7 Pro x64, to Windows 8 Pro x64, with the Windows 8 Upgrade Assistant. Everything went great, but none of the Modern UI Apps open, and they do not show any error messages or warnings, they just close right away I opened them. I tried to open Skydrive, Windows Store, Photo App,Music App, Bing, Videos , Finances and all the available Modern UI apps on my screen My screen resolution is 1080p, so it is not a resolution issue, I'm using a Windows account , but i switched to Local account but didn't solved the issue. I ran Windows Update and updated my nVidia video drivers. I also tried an app called "Metro App Troubleshooter" without luck

  • Problems installing Adobe Premiere Elements 8 Content features

    - by Walt Maken
    I recently purchased Adobe Photoshop & Premiere Elements 8. Photoshop Elements 8 installed fine, along with the additional material available via internet download. Premiere Elements 8 installed ok from the DVD. During the Premiere Elements 8 startup process the following message appears: A reduced set of content (Instant Movie Themes, Title and Menu Templates,etc) has been installed. To install the full content set, please insert your Content DVD and run Setup.exe. If you do not have a Content DVD please visit http://www.adobe.com/go/pre_additional_downloads to download the content installer. Since I didn't have the Content DVD, I did the download, which took nearly 12 hours. The extract appeared to complete at 100%, but then immediately gave the error message "A problem occurred while extracting some files. Check available space on your computer and the write privileges on the destination folder." Why would it show this error message if it had completed the extract process 100%? What step(s) do I take now to have Content installed? Do I need to go thru the 12 hour download again or, hopefully, is there something I can do that will make it unnecessary to download again?

  • Why does just splitting an Ethernet cable not work?

    - by Sin Jeong-hun
    I thought the Ethernet is logically a one-line communication bus (for argument's sake, I am excluding hubs). All machines attached on the bus hears the same signals and the machines themselves try to avoid collisions by randomly backing off. http://computer.howstuffworks.com/ethernet6.htm If so, why would splitting one Ethernet line from my home router into two and connecting two computers not work? Why do I have to add a switch to it? *What the Internet said would not work. [4 port home router] ------[one Ethernet cable]-----[simple splitter]======[two computers] *What the Internet said I should do [4 port home router] ------[one Ethernet cable]-----[switch]======[two computers] Is this because of the signal degradation (reduced electric current)? Thank you for all the answers! The reason why I did not just use the two ports of my home router is... The 4-port gigabit router is in my room, and I had put a computer in another room (also my room, though). Since a wired network is far more reliable and secure, I had bought a long Ethernet cable and and connected the computer to the router. Now I was thinking about adding another computer to that room. I could buy another long Ethernet cable, but then there will be two cables between the rooms. The one line already is a minor annoyance, so I thought if I could share the one line between the two computers in that room. A switch would work, but it requires power and is a little bit pricey. That is why I wondered why it would not work to simply split the physical Ethernet cable. Apparently I do not completely understand how Ethernet and a switch work. I just have some bit of knowledge I heard in my college class.

  • Windows 7 File Associations .mov

    - by Paul Mung
    I created a new windows 7 SP1 base image. Everything is all fine and dandy with that. So i am now installing standard applications I would like Quicktime to manage .mov files. The only problem is WMP (Windows Media Player) won't give up the association to .mov files. It's driving me crazy... i've been reading threads on how to fix file associations. I would like to do it via registry, powershell or cmdline. I cannot use GPO I've tried the following: assoc .mov=QuickTime.mov ftype QuickTime.mov="%ProgramFiles(x86)\QuickTime\QuickTimePlayer.exe" Reg add HKCU\Software\Microsoft\windows\CurrentVersion\Explorere\FileExts\.mov\UserChoice" /v Progid /d QuickTime.mov /f Reg add HKCU\Software\Microsoft\windows\CurrentVersion\Explorere\FileExts\.mov\OpenWithList" /v a /d QuickTimePlayer.exe /f Reg add "HKCU\Software\Microsoft\windows\CurrentVersion\Explorere\FileExts\.mov\OpenWithList" /v b /d wmplayer.exe /f Reg add HKCU\Software\Microsoft\windows\CurrentVersion\Explorere\FileExts\.mov\OpenWithList" /v MRUList /d ab /f Reg add HKCU\Software\Microsoft\windows\CurrentVersion\Explorere\FileExts\.mov\OpenWithProgids" /v Quicktime.mov /t REG_NONE /d 0000 /f Reg add HKCU\Software\Microsoft\windows\CurrentVersion\Explorere\FileExts\.mov\OpenWithProgids" /v WMP11.AssocFile.MOV /t REG_NONE /d 0000 /f

  • How can I route packets from one application to a virtual machine in windows 7?

    - by user836045
    I am trying to test an application running in windows 7, and I would like to send the packets it generates to a server VM (I am using virtualbox) on the local machine which will act as a simulation for when packets will be really sent over the internet to a distant server. I need to check for correctness of the packets in certain situations. Is there a way on windows to take packets produced by an application and instead of passing it to my router, pass it along to another process, i.e. my virtual machine. I'd prefer not to change any of the code on my application and would rather find an outside solution. Is there such a solution for windows 7?
