  • Accessing a persistent ssh tunnel

    - by woowaa
    How do I pass commands (shell) to a persistent SSH tunnel rather than open a connection for every instance? I have a Python scraper running on a client server which passes URL variables and shell commands to a remote host via a reverse tunnel (forwarded port), so that the URL's are then executed on the host (python fabric ssh localhost:12345 'browser open URL'). I could make the reverse tunnel persistent but how do I echo the url/command to the session? Update - ControlMaster (built into SSH) solves this one.

  • What does "32bit apps running in WOW only" means?

    - by Kiewic
    Hi! I'm trying to run an application made with Visual Basic 6.0 on a Windows 7 64 bit edition. The application is asking me for the DLL vb6es.dll. I have copied this file from a Windows XP into the C:\Windows\system32 directory, but I continue getting the same error. Searching on Google, I found the support statement of visual basic 6.0 on windows 7 and it says "32bit apps running in WOW only" for Windows 7 64 bit editions. What does this mean? Thanks.

  • Picking a linux compatible motherboard

    - by Chris
    Last time I bought a new computer (I build them myself) I got a motherboard that had really poor linux support for a long time. Specifically the audio. I had to wait months before the kernel supported the on board audio chipset. That is exactly the situation I'm trying to avoid this time around. I have some specific questions about "server motherboards" actually. I looked at a few models of server motherboards by intel, and some random models on newegg. I wasn't able to see much of a difference from regular desktop motherboard other than most had two sockets, and support for much more ram. These boards seem more popular with Linux users. Why? AMD and Intel both have server CPUs as well. Some question, what's the difference? To make this question more concrete, I was looking at this this motherboard. The main questions about it that I can't answer are: Can I get a motherboard without on board raid and audio? I wanted to get a hardware raid controller and a PCI audio card. I thought a server motherboard would be cheaper and not have these "extras", since who wants an audio card on a server? Where can I found out about Linux support for the components on this board? "Intel ICH10R", "Realtek ALC889", "Marvell 88E8056" I'm buying this computer to work as a Linux desktop for a lot of compiling, coding and audio/video work, but I don't want to rule out the possibility of installing windows and playing some games at one point. (even if the last game I got has been sitting in its box unopened for almost a year). Is it a good idea to buy a "server motherboard" and play games on it, or are desktop boards better value for this? The ultimate solution for me would be a motherboard that had GPL divers for onboard LAN, a single CPU socket, lots of PCI express and PCI. USB 3.0, and no fancy hard disk controllers since I'll be getting a separate one.

What now? Any ideas?

  • Excel Add-In not loading properly with 64-bit Excel 2013

    - by David Hyde
    I have an Excel Add-In saved to an .xla file in %appdata%\Microsoft\Addins. In the subject version of Excel it is checked on the Add-Ins list. One thing this addin does is create a drop-down menu in ThisWorkbook's Workbook_Open sub. But the menu is not created and there is no Add-Ins tab on the ribbon. No error messages. This works fine in Excel 2010 and 2007 (at least), and worked fine on the 32-bit Excel 2013 that came preinstalled on this system before I nuked it. The really maddening thing is that if I get rid of this addin and open that same .xla file, either by double-clicking or using the Open command in Excel, the menu appears as expected. I get the same behavior if I instead open the source .xls file - it all works. I've also tried saving to a .xlam file instead of .xla, but get the same bad result. Any ideas?

  • Can't restore HDD using multiple programs

    - by jonney
    Please refer to my original question about this issue. I tried GetDataBack and it doesn't seem to scan or do anything. I chose the default settings from the first screen and then on step 1 I chose my HDD that's damaged. In step 2, nothing happens. It doesn't scan or do anythong, and on step 3 it doesn't display any of my files. I have also tried TestDisk and what happens in TestDisk is that when I try to fix and rebuild the MFT, it says this: MFT and MFT mirror are bad. Failed to repair them. Here is the status of that HDD under Testdrive: I also tried this app and got no results when I tried to recover the files. I keep getting this error: Last but not least, I tried Recuva and that simply says it's unable to read the MFT. Any suggestions? I have tried various apps already and none of them seems to work.

  • Lock screen keeps making sound when screen is off

    - by row1
    I have my laptop (Asus UL20FT) on external power and hooked up to an external monitor. I keep the laptop lid closed and am using the 'second screen only' option. If you leave it on the lock screen for a short period of time the screen powers off. While the screen is off it keeps repeating a "duuuh duh duh" sound (sounds just like the device plugged in sound). The monitor is connected via HDMI and I have Microsoft and Logitech wireless USB dongles plugged in. How can I prevent this sound loop?

  • Will Parallel-port dongle work on USB-to-Parallel Adapter?

    - by Gary M. Mugford
    We have a niche program running on a Win2K laptop that uses a security dongle connected to a parallel port for authentication. The laptop is getting creaky and I spent a frustrating night last night shopping various websites for a new laptop that had a parallel port. Seems I'm about three years late [G]. The question I have, is, if I buy a new(ish) laptop and use a USB-to-Parallel Port adapter, will the security dongle work? I know I'm not being specific about the app, but it's one most people wouldn't have heard of anyways. I've been guessing the answer to my question is no, since the app won't know to send a request out to the non-existent port. But, if the process actually is that the dongle sends a message INTO the computer every now and then, then it might work. And, I'm not sure whether the dongle is only needed at program startup time or randomly. The dongle is a 'permanent' addition to the old laptop. This is all about the money. We can have a newly-updated version of the program (which won't add any features we need) for the princely sum of $2700. Or we can spend $500 on a refurbed laptop still running WinXP, add a 30 buck adapter and keep the same solid, stolid performance we've come to appreciate. But it all comes down to the dongle behaviour. Oh, and a dock won't work. The whole laptop issue is about moving about the various nooks and crannies of the building with laptop in hand. Thanks for any suggestions/guidance. GM

  • Root directory permissions on Mac OS X 10.6?

    - by Agos
    Hi, I was wondering if it's normal that the root directory / should be owned by “root”. I get asked for my password every time I want to do something there (e.g. save a file, create a directory) and I don't remember this happening before (though this may just be my faulty memory).

  • Linksys router cannot change default password

    - by Jessica M.
    My wireless internet suddenly stopped working today. I have Windows 7 and Lindsys WRT54G router. I tried to log into the Linksys setup router page by typing in www.192.168.1.1 into firefox and it prompted me for a username and password as usual. The problem is when i tried to enter my regular username and password it did not work. I finally solved my problem when I came across this post here and the very last post solved my problem. It suggested I try username: root / password: admin. For some reason the username and password has been changed. When i tried username: root / password: admin , it worked and allowed me to get into the Linksys setup page. The problem is I can't change the username or password anymore. Every time I want to log into my Linksys setup page I have to enter username: root / password: admin. I can't change the "WPA shared key" (password). For the security settings I selected WPA2Personal + AES. Also the post said "If the firmware was upgraded to non-linksys firmware - the default will be different" . The problem is I didn't update anything and I'm worried that someone installed a virus or something or somehow changed the firmware on my router. How did I get non-Linksys firmware on my router? EDIT: I figured out how to change the password when I log into the Lynksys setup page. Administration -- Management -- password. I still don't understand if my router firmware was changed or who changed it or if it happened by mistake.

  • Windows Mobile browser history

    - by kurige
    How can I retrieve a list of urls a user has visited on a Windows Mobile phone? I've written a program that successfully retrieves the visited urls in a user's cache, using FindFirstUrlCacheEntry and FindNextUrlCacheEntry - but as I understand it this is not the same as the user's actual web history. In any case it does not seem to give correct results.

  • Cleaning up temp files in OSX

    - by deddebme
    I was a Windows person for more than 10 years. Around 4 months ago, I switched to Mac, and I have never looked back. But there is one thing that bothers me, which is my Mac partition volume is losing space slowly and gradually. I am pretty sure there are a lot of orphaned temporary files laying around in the volume. I know where to find the obsoleted temp files in my Windows partition, how about in Mac OSX?

  • 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.

  • Configuring Server with no monitor

    - by Scandalist
    Sitting in front of me is an HP DL 380 Generation 4 with no monitor. I'd like to install an OS on the thing but for reasons obvious, I can't. I got excited when I found the ILO port on the back but unless you have a subscription it has limited functionality. I was thinking maybe there was some software out there that booted into some kind of remote access server? When I tested it with a monitor (A friends) I set the BIOS to boot from USB so anything I can load onto a stick should boot. Ideas? Hacks?

  • Why is the usable memory on my Macbook pro shown as 2.74 Gb when there is 4GB installed with 32bit Windows 7? [closed]

  • How does NTFS compression affect performance?

    - by DragonLord
    I've heard that NTFS compression can reduce performance due to extra CPU usage, but I've read reports that it may actually increase performance because of reduced disk reads. How exactly does NTFS compression affect system performance? Notes: I'm running a laptop with a 5400 RPM hard drive, and many of the things I do on it are I/O bound. The processor is a AMD Phenom II with four cores running at 2.0 GHz. The system is defragmented regularly using UltraDefrag. The workload is mixed read-write, with reads occurring somewhat more often than writes. The files to be compressed include personal documents and selected programs, including several (less demanding) games and Visual Studio (which tends to be I/O bound more often than not).

  • Burn bootable iso image to USB stick using dd: Won't boot (despite USB first in boot sequence)

    - by Nicolas Raoul
    I have installed Ubuntu on a Lenovo Thinkpad R500 2732, and I must update the BIOS. On the Lenovo website, I am offered this: BIOS Update Bootable CD for Windows 7 (32-bit, 64-bit), Vista (32-bit, 64-bit), XP - ThinkPad R500 I guess a bootable CD that would do a BIOS update is indeed what I need. (still wondering why it says "Windows" though... if it is bootable should not it be OS-agnostic?) Not wanting to waste a CD, I copied the image to my USB stick: sudo dd if=/home/nico/7yuj40uc.iso of=/dev/sdb1 bs=1M And rebooted, after making sure USB is first in the boot sequence. PROBLEM: It does not boot. Did I forget one step? Details about the iso image (readme): ls -lh 7yuj40uc.iso 25M file 7yuj40uc.iso /home/nico/7yuj40uc.iso: # ISO 9660 CD-ROM filesystem data '7YUJ40US ' (bootable) (Scroll to the right: it says "bootable") UNetbootin does not work because it is not a Linux image. Some people on the Internet advise to copy the content of the ISO and do other steps. This ISO has zero ISO content so it would not work. If I mount the ISO, I can see it contains zero files.

  • how do I match movement of an object from 2d video into a 3d package ?

    - by George Profenza
    I'm trying to add objects in a 3d package(Blender) using recorded footage. I've played with Icarus and it's great to capture the camera movement. Also the Blender 2.41 importer script works in Blender 2.49 as well. The problem is I can't seem to get 3d coordinates for objects. I have tried Autodesk(RealVIZ) MatchMover 2011 and gone through the tutorials. Tutorial 3 shows how to link a vertex from a 3d mesh to a 2d trackpoint, but the setup is for camera movement. Tutorial 4 goes into Motion capture, but it uses 2 videos of the same motion taken with 2 cameras from different viewpoints. I've tried to bypass that using the same footage twice, but that failed, as the 3d coordinate system ends up messed up. What software do you recommend for this (mapping 3d coordinates to 2d tracked points and importing them into a 3d package) ? What is the recommended technique ? Any good examples out there ? Thanks, George

  • How do I set the parental rating on a video?

    - by Les
    I can view the properties (right click, properties, details) of a video file and it has a field for parental rating. How can I add a rating to the file (the field is blank)? There is the problem that if I can add a rating, someone else may be able to change it to circumvent parental controls on a video player. This isn't of concern to me at this time. Edit: The file types are both .avi and .mpg. Edit 2: I own the file and have 'full control'.

For example, if I type for in a .cpp file, I get four options. I'm assuming I'm supposed to either hit tab or enter to insert them but neither works. I'm not even sure which vim plugin it is that the snippets come from (snipmate? neocomplcache?).Screenshot. The same problem happens in vim and gvim.

  • Free desktop recording / screencasting on windows

    - by Mercer Traieste
    I'm a newbie in desktop recording and screencasting. I didn't find a suitable free application to do all the things I want it to do, but I did enjoy using jing. I would expect such an application to have these features: choose the whole desktop, a region, a window to record zoom in an area, and camera move save the recorded movie to a compressed format have basic editing tools have the mouse highlighting feature (either a sonar blip or something similar) highlight window/field on the screen, any trick will do display pressed keys/key combinations (like iphone does) So the question is: Which free desktop recording/screencasting software would you recommend on windows? It doesn't have to have all those features, just tell me your favorable experiences. Please suggest tools that would do mouse/keys/areas highlight tricks. I'm open to commercial software too, but I would prefer a free one. Thank you!

  • Blocking internet poker applications

    - by Matthew Savage
    I 'look after' the wireless internet for a cafe where I live, and we've noticed that there's quite a substantial slow down of internet speeds when certain users are playing internet poker. I've put in filters to block any HTTP traffic referencing gambling and poker etc, however I want to be able to block any applications (i.e. poker clients) which don't use HTTP. I've tried searching around for a list of poker clients and perhaps their ports, but have had no real luck. Does anyone know what these might be?
