• How to retry connections with wget?

  - by Andrei

  I have a very unstable internet connection, and sometimes have to download files as large as 200 MB. The problem is that the speed frequently drops and sits at --, -K/s and the process remains alive. I thought just to send some KILL signals to the process, but as I read in the wget manual about signals it doesn't help. How can I force wget to reinitialize itself and pick the download up where it left off after the connection drops and comes back up again? I would like to leave wget running, and when I come back, I want to see it downloading, and not waiting with speed --,-K/s.

• Add folder name to beginning of filename - getting multiple renames

  - by Flibble Wibble

  I've used dbenham's excellent response to the question of how to add the folder name to the beginning of a filename in a cmd script. @echo off pushd "Folder" for /d %%D in (*) do ( for %%F in ("%%~D\*") do ( for %%P in ("%%F\..") do ( ren "%%F" "%%~nxP_%%~nxF" ) ) ) popd What I'm finding is that seemingly randomly (though it probably isn't) sometimes the script will run through several child folders and rename correctly but then it gets to a folder where it gets stuck in a loop and starts adding the folder name repeatedly to the file inside. I have 90,000 files in 300 folders to rename this weekend. Any chance you can guess the cause? PS: Is there a maximum number of files that are acceptable in each folder?

• Why no Win16 support in 64-bit Windows?

  - by dsimcha

  My understanding (from Wikipedia) is that the x64 instruction set supports executing 16-bit protected mode code from long mode, but cannot execute real mode code without being switched out of long mode because long mode lacks virtual 8086 mode. Therefore, it stands to reason that real mode DOS apps can't be run in Win64 w/o software emulation or dynamic translation. However, why was support for Win16 protected-mode apps excluded when support for them seems (at least at first glance) to be reasonably implementable and is included in newer versions of Win32? Was it just a matter of demand not being high enough to justify implementation costs (and the win32 version was already implemented), or is there a good technical reason?

• I'm trying to setup Xvfb to run an GUI app on a remote server with no display

  - by jz87

  I have a 3rd party java app that I need to run on a remote server. Unfortunately, the app is designed for the desktop and assumes a GUI is available. The thing is I would like to leave this app running on the remote server without having to tie up my desktop machine with a persistent VNC connection to the remote machine. I'm trying to setup Xvfb on the remote machine so emulate a graphical environment, connect to the remote machine via VNC to launch the app and configure parameters and then log off and let it run. Here's what I have so far: I have ubuntu 11.04 server apt-get install xvfb apt-get install fluxbox apt-get install x11vnc Xvfb :1 -screen 0 1024x768x16 & fluxbox & At this point I run into a problem because it gives a very undescriptive error: Cannot connect to server. How do I know if the server is running and that it's running properly?

• Automatic switching between monitor configurations

  - by Michael Aquilina

  I have a laptop and an external monitor and i was wondering if there was a simple approach to switching between multiple monitor configurations based on the detected available displays. For example: When i am at home and i plug in my external monitor i would like this to automatically become enabled and the laptop screen to become disabled. As soon as i pull out the display cable for the external monitor, i would like the laptop screen to automatically become enabled. I was expecting this to just "work" just like it does in windows - but it seems to be much harder than that. I am aware of the xrandr command to turn displays on and off but i cannot seem to find a way to get this to work the way i describe above. I had also found this post about switching between multiple monitor configurations and the results seem a bit inconclusive. However i was hoping that with xrandr there would be a simpler solution. For me, the fact that when i pull out my external monitor the screen just goes black and i get an error message is a big issue holding me back from making the complete switch to linux as i move around alot as a student. My OS of choice is currently Kubuntu 12.04 but i am willing to change to something else if it provides a better way of setting up the described setup.

• OS X: How to create a user account with access to the applications that she has installed only.

  - by pmurillo

  Till now, I've been the sole and proud owner of an iMac. I've always logged in as an administrator and I've also installed a bunch of software following the standard procedure of dragging and dropping it into the Applications folder. This is about to change, as sharing it with a friend makes a lot of sense now that I only have time to use the computer in the mornings, and she can only use it at nights. I thought this was going to be really easy: Just create a user account for her and that's all, I thought. Unfortunately, this is not the case. When she logins into the computer using her username and password, she has access to the same applications I've installed. Even the same applications that I setup to automatically start when I login start for her when she does. How can I setup a user that has only access to the applications that she has installed, but none of the ones installed by other users? Many thanks

• How do I decide what type of programmer I want to be?

  - by Pearsonartphoto

  I've been working at my current work for some time, and I'm considering a bit of a change of careers. I'm trying to decide what it is exactly that I want to do, and I'm really just not sure. I'm not wanting a solution for my particular case, but what I'd like to know are some generalities of things I can look for. Here are some positions that I'm considering, and what my definitions are (I'm probably calling them something other than what is standard, but hopefully this will do for now). I'm looking for quizzes, articles, explanations, or anything that can help me figure this out. Manager - Managing programmers in some sense, mostly in making sure they are kept working. Coder - A person who is told to make a program do XYZ, and makes it do that. Doesn't have to model anything, or come up with formulas. Algorithm Designer - A person who comes up with a way to make software do something, but doesn't necessarily code that program, at least, not in it's final form. QA - A person who tests code for bugs, preferably with the code in hand. Architect - This person figures out how all of the pieces fit together, is a technical manager of sorts. Maintainer - This person takes someone else's existing code, and makes sure it is fixed when issues arise. Also of some note is figuring out what industry I want to work in. Feel free to add any of your own categories.

• Cross platform KVM over ethernet

  - by Falmarri

  I'm not sure if this exists, but this is what I'd like to do. I have a laptop and a desktop that I work on about equally. The laptop runs windows 7 and the desktop is on kubuntu 10.04. What I want to be able to do is be able to drag my mouse accross my screen and have it act like my laptop is a second monitor. Whereby I can use my desktop mouse, drag it say to the left off of my desktop monitor, and use it on my laptop (I don't care about the keyboard, just the mouse). Is that possible? Are there any other solutions that exist? I'd prefer not to have a physical kvm switch.

• Amazon - install a complete server on EBS

  - by user1169575

  is it possible to install a full working OS with a webserver, db, and all needed stuff on an EBS storage? If so, would I immediatly gain benefits by mounting this EBS on a better instance? Otherwise (if I cannot install a complete image, or if you don't think it's reasonable) can I install the software so that I only need to mount the EBS on a new instance to have it working? I purchased a Medium Reserved Instance, but when there will be the need to get a better instance I'd like to move the whole db/website, I'd simply buy a better instance and then attach the EBS. Is it possibile? I'm imaging about it like an hard drive that would be mounted on a better server. Of course, more RAM would allow me to increase caching limits, and that's ok, but I don't want to reinstall anything (the main website is a magentocommerce and it's pretty painful to move it). P.S. is the Standard EBS (100 IOPS) valid or do I need to choose a Provisioned IOPS (up to 1000 IOPS)?

• Access denied to EFS encrypted files after PC joins domain

  - by mjmarsh

  I'm experiencing strange behavior with Windows Encrypted File System: I have a machine that is in workgroup mode (not joined to a domain) I encrypt an entire directory structure on the machine (basically a folder and subfolders with data files for my application). My application writes and reads files from the encrypted file hierarchy as a local Windows user (let's call the account 'SecureUser'). This works fine I then join the PC to a domain (Let's call it 'TEST') Afterwards, processes running as the local 'SecureUser' account can't read the files it wrote originally when it was off the domain (What is also strange is that the files are listed as "read only" now and I cannot unset this flag via Windows Explorer or the command line, even though it looks like it succeeds) I then 'un-join' the PC from the domain and everything works again Is there something about changing domain membership on a PC that changes the behavior of EFS so that previously encrypted files cannot be read, even by the originating user? Thanks in advance

• How do I install Visual Studio 2010 Express somewhere besides C:?

  - by TwentyMiles

  I have a SSD as my primary (C:) drive, mainly used for quickly loading games. It's pretty small (~30 GB) so I want to keep things that don't really need a speed boost off of it. I attempted installing the Visual Studio 2010 Express beta last night, and It claimed to require 2.1 GB of space so I changed the install directory to a secondary, non-SSD drive. After this, the installer said that it would use 1.8 GB on C: and ~200 MB on the secondary drive. While this token gesture of moving 1/10 of the app to the place I told it to is cute, I really want to install everything I can to the secondary drive. Is there any way to install all of Visual Studio 2010 Express to a drive besides C:?

• Server installation logging / logbook / diary?

  - by The MYYN

  Are there some ways field-tested ways to keep a kind of logbook for a server? Including: software installations (and de-installations) custom configurations (e.g. of a webserver, ssh daemon, etc.) personal notes The big picture. I am preparing a server and would like to extensively document the state and how it was established over time, so that a new person can easily see, what's going on and why. The setup is not too complicated, but I would like to do it anyway. I once used something like Maintain /etc with mercurial on Debian and it was nice, but I am looking for a little more flexible solution. Addendum: So I am interested in logging and documentation first. In an ideal world however, I would like to have a command, which in a few steps would take me from a bare newly installed unix system to a functional environment with all the components setup and in place by the means of, say an 'executable' log. But that would be very ideal, I imagine.

• Hylafax with serial over IP modem

  - by zero_r

  I'm looking into virtualizing a Hylafax server which currently runs on a dedicated hardware running CentOS with a Divalogic card. The main issue obviously is, how to connect the modem to the VM. There are serial over IP devices available at digi.com. Maybe there are others? Regarding digi.com devices, as far as I understood one can install the RealPort software and then have a /dev/ttySx device presented to the Linux server. This device then can be used as serial connection to the modem. Does someone have such a configuration in place? Or does someone have another idea to virtualize a Hylafax server (outbound faxes only). Thank you in advance

• Motherboard or Processor Problem

  - by bradlis7

  My computer is broken, but I'm having trouble narrowing down the issue. I replaced the power supply, because I assumed that was the issue, but it has the same problem. The issue started with my computer starting the fans and running, but it didn't get to the BIOS screen for about 10 seconds. Now it refuses to do anything when the power button is pressed, except when I turn off the machine and take the processor out for 10-20 seconds, then put it back in, I came hit the power button immediately, and the fans start for 1/2 second, and quit. Does this sound like a is a processor or motherboard issue? I removed all components, so I know that the issue is with one of these two things.

• 'Unlimited' free trial of Windows Server 2008 by deleting and reinstalling VM? [closed]

  - by MrVimes

  I am using Virtual Machine software (VirtualBox) to learn Windows Server 2008 R2 Network Infrastructure (70-642). Trouble is - I'm learning at an extremely slow pace and so the trial periods of my virtual machines are close to running out. If I delete the VMs then install WS2008R2 from scratch on new VMs is that violating the acceptable use policy of Microsoft? I am aware that I can extend the trial, but it seems I can only do that by 10 days at a time. Also I think having to re-install from scratch is a good way to reinforce the knowledge.

• Computer to act as keyboard

  - by Joe

  Title explains it. Imagine this example, Host computer connects to a Client computer via male/male usb connection. Client computer acknowledges this connection as a new device, in this case a keyboard. The host computer can now send key events to the client computer and the client computer would process them as a normal keyboard event. I did a whole lot of searching in the internet and really have drove down many dead ends. Any tips would be appreciated. Note* this is a physical connection. The client computer should not have to install any software for this to function (The host will completely spoof as a keyboard).

• Troubles doing transparent proxy for virtual machines

  - by Dan H

  Hi iptables gurus. First here is the basic topology: Internet | Gateway | Workstation---eth0---virbr0 | +-----+-----+ | | | vm1 vm2 vm3 I need to test a traffic analyzer running on my workstation, listening on some port (say 8990) on eth0. The rule [I think] I want is "any packets leaving virbr0 going anywhere to port 80 must instead go to port 8990 on eth0". My software running on port 8990 does its own check of the NAT packet mangling to push the packets through after it inspects them. I've been banging my head on this, with different variants of: iptables -t nat -A PREROUTING -i virbr0 -p tcp --dport 80 -j DNAT \ --to 10.0.0.10:8990 And I've tried the more generic method of using the mangle table with --set-mark and ip rule add fwmark, but I'm not getting it. I guess what's confusing me is that everything runs on the same box. Thanks for any guidance.

• Can't `mount -o loop` an ISO from an NFS share (RHEL)

  - by warren

  I have a large NFS share with a variety of software ISOs on it. I've only tried this on Red Hat Enterprise Linux, but when trying to do the following, the mount comes back with an error indicating no permissions to mount. Why would this be happening? NFS is mounted thusly: mediaserver:path/to/isos /media/nfs This is the mount call that fails mount -o loop /media/nfs/product.iso /tmp/product If I copy the ISO, there is no issue. The NFS share is mounted rw. How can I loop mount the ISO from the NFS share without copying it first?

• How can I prevent JungleDisk/MacOS X (10.6) creating a local volume for a removed external drive?

  - by Rew

  Ok, here is situation: I use JungleDisk to sync an online folder on to a external drive connected to my Mac. If I right click Finder, click Go to Folder... then type /Volumes/ I see the drive linked here. Once I remove the external drive, an actual folder is created here in the name of the external drive, JungleDisk continues to copy files to this folder, rather than stop. Is this a feature of Mac OS X? Can I turn if off? After I re-connect my external drive, the link to the drive is appended with a 1 (so if I called the drive SpareDrive it becomes SpareDrive 1 as the newly created folder is called SpareDrive. I realise my explanation isn't very clear, but anyone understand this, and knows how to prevent it happening please let me know. PS: I have a low reputation as I don't use this often, I tend to use stackoverflow, but will check back here for answers.

• I want to easily switch accounts for Twitter - is there a Firefox/Chrome/IE plug-in to do this?

  - by Edelcom

  I have several Twitter accounts to which I post messages. One is a personal, one is a professional, and a couple for each software system I developed. Does any one know of a plug-in for one of the major web browses on Windows or program that allows me to easily login to multiple Twitter accounts and easily switch between them ? I now have the 4 major browsers installed on my computer , each with it's own Twitter account (with the password and login info saved), but I think there must be a better way. On a side note: it is getting harder and harder to know to which StackOverflow alike site a question must be posted. So I hope this question here is considered on-topic.

• How to make my display Grayscale?

  - by Oldarney

  I want to reduce the saturation of my laptop monitor to the point that it is almost grayscale. That's the goal. Intel and Asus don't have an answer. Asus Splendid and the intel graphics control panel can increase the saturation, but not lower it. I would prefer a software solution, although I DIY'ed a vga grayscale adapter for my desktop. I have an Asus UL30A with an Intel GMA 4500MHD. I know that the latest ATI cards, windotosh's and high end nvidia cards all support control panel desaturation. Why? black and white makes me 3 times more productive.

• Iptables to lock down compromised server to a single ip

  - by ollybee

  I have a Linux server which is compromised, I can see nasty looking perl scripts executing with root privileges. I want to get some data off it before I wipe it. How can I block all inbound and outbound traffic except for my ip? It's a Centos server I assume i can do this with iptables? I'm aware a the server is rooted there is a possibility that attackers could have made changes on the server that would prevent this from working. Ill be testing to make sure and only have the server online for a couple of hours before it is nuked.

• Windows 7 extremely long startup

  - by Tyler

  Windows 7 before it even gets to login. On the "starting windows" splash screen takes no less than 15 minutes to finish more like 25 minutes most times. During this time the hard drive activity led indicator is blinking maybe once every 20 seconds. When I finally get to the desktop everything runs normally. I have unplugged all peripherals with same result. Ideas? It's 32bit. 4gig memory. Fast CPU which I can't recall off the top of my head.
