  • Unable to Set Up Remote Access on Windows Home Server

    - by Matt Hanson
    When trying to turn on Remote Access on my Windows Home Server (HP MediaSmart Ex485, MediaSmart Server 3.0, Power Pack 3), I am not able to continue through the wizard as this first check fails: "Verifying that your remote Web site is available locally" Everything else on the server works fine, including being able to: Ping server RDP to server Access all shares as expected Browse to both http://servername and http://servername:55000 I have noticed though that I am unable to browse to http://servername:56000 as I should be able to do. I've performed a server recovery to reset the installation to factory defaults, with no such luck.

  • Create disk image from a remote system

    - by cringe
    I want to backup a disk from a remote system, but the remote system itself has not enough space available. Now I want to use ddand pipe the output through ssh, but I can't figure out how to do it. I read several sources on the web, but I'm stuck now. Can someone please point me to a good resource or write down the command line with explanations?

  • Should certain math classes be required for a Computer Science degree?

    - by sunpech
    For a Computer Science (CS) degree at many colleges and universities, certain math courses are required: Calculus, Linear Algebra, and Discrete Mathematics are few examples. However, since I've started working in the real world as a software developer, I have yet to truly use some the knowledge I had at once acquired from taking those classes. Discrete Math might be the only exception. My questions: Should these math classes be required to obtain a computer science degree? Or would they be better served as electives? I'm challenging even that the certain math classes even help with required CS classes. For example, I never used linear algebra outside of the math class itself. I hear it's used in Computer Graphics, but I never took those classes-- yet linear algebra was required for a CS degree. I personally think it could be better served as an elective rather than requirement because it's more specific to a branch of CS rather than general CS. From a Slashdot post CS Profs Debate Role of Math In CS Education: 'For too long, we have taught computer science as an academic discipline (as though all of our students will go on to get PhDs and then become CS faculty members) even though for most of us, our students are overwhelmingly seeking careers in which they apply computer science.'

  • What is the relationship between Turing Machine & Modern Computer ? [closed]

    - by smwikipedia
    I heard a lot that modern computers are based on Turing machine. I just cannot build a bridge between a conceptual Turing Machine and a modern computer. Could someone help me build this bridge? Below is my current understanding. I think the computer is a big general-purpose Turing machine. Each program we write is a small specific-purpose Turing machine. The classical Turing machine do its job based on the input and its current state inside and so do our programs. Let's take a running program (a process) as an example. We know that in the process's address space, there's areas for stack, heap, and code. A classical Turing machine doesn't have the ability to remember many things, so we borrow the concept of stack from the push-down automaton. The heap and stack areas contains the state of our specific-purpose Turing machine (our program). The code area represents the logic of this small Turing machine. And various I/O devices supply input to this Turing machine.

  • Remote Router Access For Linksys WRT54GL

    - by Tim
    Hi, I just set up a wireless network at home using a Linksys WRT54GL. All was fine except that I can still access 192.168.1.1, the configuration setup page of the router, within the local wireless after I disabled "Remote Management". I think if remote access is indeed disabled, one can access my router setup page only by using a cable connecting from his computer to the router. Is this true or am I wrong? Thanks and regards!

  • How to get my IR remote to work? Lirc can't see it

    - by user1234567
    I'm using Ubuntu 11.10 (amd64) and I'm trying to get my infrared remote control working. The IR device is a part of a DVB-T USB stick (Based on a RTL2832u chip). I'm using these drivers - it's the only way of getting this device to work under 11.10 that I found. It's a big impromevent from previous Ubuntu version, where I had to edit the driver's code. The device works quite great - and the IR part of it works, too. The driver's page says that the code it's in alpha stage, but I'm pretty sure that my issue has nothing to do with that. If, and only if driver's module is loaded with parameter rtl2832u_rc_mode=2 (which means "use NEC protocol for IR") the remote kind of works, I can see this by running cat /dev/.. ../input6 - when I press a button, random letters appear. The remote works just like a keyboard, but keys are totally messed up - when I press '5' the volume goes down, etc. I would like to use Lirc to fix that, but Lirc can't detect my device (i.e. irw shows nothing). I suspect, it's because something gets into control of the device and sets it up as a keyboard. Lirc seems to be working, it's KDE settings module works too, but it just doesn't detect the device. The Lirc page describes this issue, but since 2009 - the last year when that page was updated, Ubuntu moved from HAL (described there) to DeviceKit, rendering provided instruction useless. I had a similar issue with my previous remote, but the keys were not messed up so much - the remote was usable, so I gave up trying to get Lirc working. I tried the answer provided here, but it changed nothing. I also tried forcing lircd to use my device, but this didn't work too: for i in /sys/class/input/input* ; do echo -n "$(basename "$i"): "; cat "$i/name"; done shows input0: Power Button input1: Power Button input2: Logitech Logitech USB Keyboard input3: A4Tech PS/2+USB Mouse input6: IR-receiver inside an USB DVB receiver But when I run: lircd -n --device=name='IR*' as root (also tried with the full name) I always see: lircd-0.9.0[3983]: lircd(default) ready, using /var/run/lirc/lircd lircd-0.9.0[3983]: accepted new client on /var/run/lirc/lircd lircd-0.9.0[3983]: could not get file information for name=IR* lircd-0.9.0[3983]: default_init(): No such file or directory lircd-0.9.0[3983]: Failed to initialize hardware So, how to set up Lirc with devinput driver in such case?

  • realtime window remote connection?

    - by terrani
    Hi, I am trying to control a desktop (HTPC) using my laptop. I currently use Teamviewer, but it is pretty slow. I used to use window remote desktop connection and it was pretty fast. The problem with window remote desktop connection is that it does not support realtime. By "Realtime", I mean it does not display what I am doing on the computer being controlled. Any suggestions?

  • Boot to remote desktop

    - by mike737
    I'm trying to find out what existing options there are out there to boot a machine into a remote desktop (RDP). Ideally the user would have a USB key and just plug it into the machine and boot via it establishing an RDP connection to their virtualised enviroment (stored on a server). Essentially the anticipated flow will be Power On - Boot sequence - Remote Desktop Login screen.

  • Rsync: remote source and destination

    - by goncalopp
    If both source and destination are remote, rsync complains: The source and destination cannot both be remote. rsync error: syntax or usage error (code 1) at main.c(1156) [Receiver=3.0.7] Is there a insurmountable technical obstacle to making rsync do this? Or it's simply a case of it's-not-yet-implemented? It seems relatively easy to create a local buffer in memory that mediates the transfer between two remotes, holding both hashes and data. Conversely, is there other (unix) software that implements this functionality?

  • Remote Desktop to Windows 2008 hosted in VirtualBox makes host unresponsive

    - by Robert Wagner
    I have installed Windows 2008 R2 SP1 in a VirtualBox VM. It works fine, except that if I Remote Desktop (RDP) to the VM from the host (machine running VirtualBox, Windows 7 SP1), after a minute or so the windows shell becomes unresponsive. I can no longer start task manager, open the start menu or switch applications. Keyboard input also drops some keys. Mouse movement is not affected. Any idea what is causing this? NB: This is Windows RDP, not the remote display built into VirtualBox

  • How does Windows Remote Desktop Connection Work?

    - by Devoted
    How does Windows Remote Desktop connection work? An IP address is used to connect to the computer but....how can that IP be accessed from anywhere? If, for example, the IP address is 192.168.1.55, there MUST be another 192.168.1.55 somewhere else in the world. How does Remote Desktop know which one to connect to? Thanks so much

  • Can I Be Alerted On-Screen Each Time Someone Remote Desktop's Onto My Windows 2003 Server

    - by Sohnee
    I work all day on a Windows Server 2003 machine and have noticed people "borrowing" my machine by using Remote Desktop to log in. This is pretty much "normal behaviour" at the company I work at, but I'd like to know when this is happening. Is there any way I can be alerted each time someone remote desktop's onto my server? A simple "Bob has logged in" would be great - and I imagine there is a facility somewhere to enable this.

  • Studying computer science - what am I getting myself into?

    - by clankercrusher
    I'm a student considering the possibility of studying computer science. I've picked up programming indie games and websites as a hobby and I really enjoy it. Despite my fairly positive experience, I somehow get the feeling that computer science in the business world will be completely different than do-it-for-fun game making. Since I'm interested in the field and I'd like to study well, I want to prepare myself for the onslaught. (If that’s even possible) What are some of the most important principals I need to know if I decide to study computer science? What will I need to know about computer science that a University probably won't teach me? Is there any way I can get hands on experience before or while I'm at a University? What am I getting myself into? P.S. Is this the right stack exchange site for this type of question?

  • Load local file in place of remote file (HTTP) address in Windows

    - by ev
    Hi there, I am trying to achieve something that you might typically use a hosts file for, but that isn't suitable here. I want a Windows PC to refer to a local file (I can serve it from a web server at localhost if needed) when it attempts to fetch a certain remote file via HTTP. However, I need other files from that particular remote web server to be fetched as usual. Any help appreciated.

    I created a database link using database link. create public database link REMOTEDB connect to REMOTEUSER identified by REMOTEPWD using 'REMOTEDB'; then i create a table in remote db like, create table MYTABLE@REMOTEDB (name varchar2(20))); It says, ORA-02021 DDL operations are not allowed on| a remote database.. Will this Not work on any cost, or am i just missing some permissions to create ?
