  • Laptop powering off after 10 mins or so

    - by Jack
    I have no OS installed, and I am trying to use a linux boot disc. However it is not a linux problem....if I just leave the computer on at the no operating system found message, it still turns off. I thought maybe it was overheating, but I am 90% sure that is not the problem. What else could cause this? I should have mentioned, it's a laptop.

  • Windows Desktop Switchboard / Toolbar

    - by codex73
    I'm researching a way to provide a somewhat custom toolbox, widget or switchboard which will reside on users desktop visible at most times for easy access to resources. Resources could be websites, local computer applications, custom api, etc. Compatibility should be Windows XP, 2008 Server, 7, Vista. Unsure if I should custom build an application with Visual Studio, Customize a Open Source Package or what could be a good simple implementation. Any advice or comments on this will be greatly appreciated.

  • Practical way to implement prevention of IP Spoofing

    - by user1369975
    I am an undergraduate Computer Science student and was hoping to gain some knowledge of ways to help prevent IP spoofing but all the resources I have tried out elaborate this concept in a theoretical way. I want to try out my hands at one of the techniques like: http://en.wikipedia.org/wiki/Port_knocking http://en.wikipedia.org/wiki/SYN_cookies How do I simulate this whole situation in my own system were I myself am the attacker and I myself have to defend it? And once I have gained an understanding of it, then how do I start translating that into programming terms?

  • Wondering about the Windows 7 serial number my laptop has, and its uses.

    - by overmann
    So that's the serial number of my pre-installed windows copy, I take it. But am I allowed to use it again when, say, I don't know, my system gets crippled by a sneaky virus? If I format my computer and install windows starter again from a USB drive (speculating. I've never format before, I suppose is completely possible) Is that serial number still valid? I'm talking about the number printed on the back of my laptop.

  • power management of USB-enclosed hard drives

    - by intuited
    With a typical USB hard drive enclosure, is the full range of drive power management functionality available? In what may be an unrelated matter: is it possible to suspend a PC without unmounting an attached USB-powered drive, and then remounting it on resume? This is the behaviour I'm currently seeing (running Ubuntu linux 10.10). Are there certain models or brands that provide more complete control over this aspect of drive operation? My Friendly Neighbourhood Computer Store carries (part of) the Vantec Nexstar product line.

  • Is it possible to run several virtual machines each with independent mouse+keyboard on a single PC?

    - by chiurox
    My goal is to instead of buying 4 separate basic PCs (plus the obvious peripherals), buy just one fast PC and the peripherals. I'm wondering if I can use a more powerful computer, say, one with core i7 and plenty of RAM, with 2 video cards (total of 4 monitor outputs) to run 4 or more virtual machines (WinXPs) so instead of having 4 individual machines, I'll be having just one. However, the catch is, is it possible to have a pair of mouse and keyboard + input/output audio for each of these virtual machines?

  • Why can't I share a folder on Vista?

    - by Ken
    On Windows Vista, I right-click on a folder, Properties, Sharing tab, and either "Advanced Sharing" or "Share"-"Share" causes an error: Windows File Sharing This program will not run Access is denied. Close My user account is an "administrator" on this machine. I think this behavior changed since my computer was added to the new domain recently. I have other folders shared (from long ago), and they continue to be shared just fine.

  • I keep getting a Java incoming connections pop up

    - by 1.21 gigawatts
    I keep getting the following message, "Do you want the application “java” to accept incoming network connections?" First of all, what application? Second, if it's part of the browser, which sometimes the browser isn't open, it doesn't show me what page is requesting it. "Application" is very generic. Third what does that mean? Is it asking if anyone on the internet can make connections to my computer?

  • Configure server on network to analyze traffic

    - by Strajan Sebastian
    I have the following network: http://i.stack.imgur.com/rapkH.jpg I want to send all the traffic from the devices that connect to the 192.168.0.1 router to the 192.168.10.1 router(and eventually to the Internet), by passing through the server and an additional router. Almost 2 days have passed and I can't figure what is wrong. While searching on the Internet for some similar configuration I found some articles that are somehow related to my needs, but the proposed solutions don't seem to work for me. This is a similar article: iptables forwarding between two interface I done the following steps for the configuration process: Set static IP address 192.168.1.90 for the eth0 on the server from the 192.168.1.1 router Set static IP address 192.168.0.90 for the eth1 on the server from the 192.168.0.1 router Forwarded all the traffic from 192.168.0.1 router to the server on eth1 interface witch seems to be working. The router firmware has some option to redirect all the traffic from all the ports to a specified address. Added the following rules on the server(Only the following, there aren't any additional rules): iptables -t nat -A POSTROUTING -o eth1 -j MASQUERADE iptables -A FORWARD -i eth1 -o eth0 -m state -–state RELATED,ESTABLISHED -j ACCEPT iptables -A FORWARD -i eth0 -o eth1 -j ACCEPT I also tried changing iptables -A FORWARD -i eth1 -o eth0 -m state -–state RELATED,ESTABLISHED -j ACCEPT into iptables -A FORWARD -i eth1 -o eth0 -j ACCEPT but still is not working. After adding the following to enable the packet forwarding for the server that is running CentOS: echo 1 /proc/sys/net/ipv4/ip_forward sysctl -w net.ipv4.ip_forward = 1 After a server restart and extra an extra check to see that all the configuration from above are still available I tried to see again if I can ping from a computer connected to 192.168.0.1/24 LAN the router from 192.168.1.1 but it didn't worked. The server has tshark(console wireshark) installed and I found that while sending a ping from a computer connected to 192.168.0.1 router to 192.168.1.1 the 192.168.0.90(eth1) receives the ping but it doesn't forward it to the eth0 interface as the rule tells: iptables -A FORWARD -i eth1 -o eth0 -j ACCEPT and don't now why this is happening. Questions: The iptables seem that don't work as I am expecting. Is there a need to add in the NAT table from iptables rules to redirect the traffic to the proper location, or is something else wrong with what I've done? I want to use tshark to view the traffic on the server because I think that is the best at doing this. Do you know something better that tshark to capture the traffic and maybe analyze it?

  • Linux: permission to read file from /sys/kernel/debug wihout root privileges

    - by gogowitczak
    I'd like to read small text file, located at: /sys/kernel/debug/vgaswitcheroo/switch without root permissions. It contains information about graphic cards (dedicated ATI Radeon and integrated Intel HD3000). I wrote a simple script displaying infomation I need, but it works only with root privileges. I already tried changing file & folder permissions, but when I restart my computer, the problem remains. Is it possible to permanently change that file permissions or owner?

  • What is the reason partitioning is usually a step in installing multiple OS's?

    - by P.S.
    What is the reason partitioning is usually a step in installing multiple (2) operating systems on the same computer? Does an operating system have to have it's own partition to run or can it run in the same partition as another operating system? (i.e. -can two of the same flavor run in the same partition but if you have one Linux and one windows it needs to be partitioned?) Is it necessary to make disk partitions to run multiple operating systems?

    - by Darqer
    I'm logging through Remote Desktop to windows 7. Some other users sometimes tries to connect to the same computer, then a message box pops up with information that I have 30 to break this trial or I will be logged off. Sometimes I'm away and then I'm being logged off and when I come back I have to log on again. Is there a way to turn off this functionality for single user. Is there some application that always break this login process ?
