  • What are the different ways of remotely connecting to your computer?

    - by Rogue
    I'll be leaving for uni soon and would like to know the different methods of connecting remotely to my home pc. I know about VPN but are there any other ways? Also how secure is each of this method as I wouldn't want snoopers on my home-pc especially when I'm away. Also can i set up a remote connection to start and shut down my computer My operating system is windows, but if linux is more secure i would be willing to switch.

  • Trying to grok Linux quotas, where is the data stored?

    - by CarpeNoctem
    So all the tutorials and documentation for the Linux quota system has left me confused. For each filesystem with quotas enabled/on where is the actual quota information stored? Is it filesystem metadata or is it in a file? Say user foo creates a new file on /home. How does the kernel determine whether user foo is below their hard limit? Does the kernel have to tally up quota information on that filesystem each time or is it in the superblock or somewhere else? As far as I understand, the kernel consults the aquota.user file for the actual rules, but where is the current quota usage data stored? Can this be viewed with any tools outside repquota and the like? TIA!! Update: Thanks for the help. I had already read that mini-HOWTO. I am pretty clear on the usage of the user space tools. What I was unclear on is whether the usage data was ALSO in the file that stored per-user limits and you answered this with a yes. From what I can tell, rc.sysinit runs quotacheck and quotaon on startup. The quotacheck program analyzes the filesystem, updates the aquota.* files. It then makes use of quota.h and the quotactl() syscall to inform the kernel of quota info. From this point forward the kernel hashes that information and increments/decrements quota stats as changes occur. Upon shutdown, the init.d/halt script runs the quotaoff command RIGHT before the filesystems are unmounted. The quotaoff command does not appear to update the aquota.* files with the information the kernel has in memory. I say this because the {a,c,m}times for the aquota.user file are only updated upon a reboot of the system or by manual running the quotacheck command. It appears - as far as I can tell - that the kernel just drops it's up-to-date usage data on the floor at shutdown. This information is never used to update the aquota.* files. They are updated during startup by quotacheck(rc.sysinit). Seems silly to me since that updated info had already been collected by the kernel. So...in conclusion I am still not entirely clear on the methods. ;)

  • Trick XP into having more RAM?

    - by Industrial
    Hi everyone, Are there any way known to trick an computer with XP to appear to have more RAM? I need to install a specific program (which fits in my system requirements), which is bundled with a number of other programs on an DVD. Unfortunately, the other programs besides the one that I need demand twice the amount of RAM that's available on my computer and the installation is closed due to this. Can I trick my XP computer into have more RAM temporarily to bypass the block in the install executable? Thanks

  • What are your favorite open source tools? (that is not very famous)

    - by sucuri
    I believe every system administrator is used to open source by now. From Apache to Firefox or Linux, everyone uses it at least a little bit. However, most open source developers are not good in marketing, so I know that there are hundreds of very good tools out there that very few people know. To fill this gap, share your favorite open source tool that you use on your day by day that is not very famous. *I will post mine in the comments.

  • How can I use my built-in AMD Radeon 7670m instead of Intel HD 4000 Graphics?

    - by gururaj
    i recently bought a DELL Inspiron 15R 2012m Series Laptop. It comes with a built-in AMD Radeon 7670m graphics card. I installed PES 2012, when I checked the system specification (an option in that PES 2012 game ). I came to know that game runs with Intel HD4000 Graphics and not with my AMD card. I also changed the swithchable graphics and assigned High Performance to PES2012, but the game still runs on Intel HD4000.

  • Optimal disk partitions for database setup (15 Drives)

    - by Jason
    We are setting up a new database system and have 15 drives to play with (+2 on-board for the OS). With a total of 15 drives would it be better to setup all 14 as one RAID-10 block (+1 hot spare) OR split into two RAID-10 sets one for Data (8 disks) and one for logs/backups (6 disks). My question boils down to the following: is there a specific point where having more drives in a RAID-10 setup will out preform having the drives broken into smaller RAID-10 sets.

  • OSD with ConfigMgr across subnets?

    - by MattUebel
    I am trying to deploy a system image from one subnet to another. Subnet A contains the SCCM server. Subnet B contains the workstation that I want to build. Subnet B contains a DHCP server with a scope configured to service the workstations. How would I configure the DHCP server so that it tells the workstations to look at the SCCM server on Subnet A as its bootserver?

  • How to flip video feed that's presented upside down?

    - by Zuul
    Skype an other applications running under windows 7 Ultimate are presenting the video captured from the laptop built-in webcam upside down. I've tried many solution that I was able to find regarding issues like this, but to no avail. Some of the most relevant are discussed here: From Skype Support Network, the thread why is my video image of myself upside-down??? From ASUSTek Forums, the thread Built-in camera upside down Both present several potential solutions to this issue, but I've been unable to fix it for the laptop ASUS U6S. What I've already tried: Changing Drivers The driver that works must be the one from Windows, all others available from ASUS drivers either don't install or install but the webcam doesn't provide any video feed. This disallows all options that concern using an older driver or editing the .inf file as to manually adjust the settings. ASUS does not provide drivers for Windows 7, so I've used drivers from Windows Vista 32 Bit. Using the application manycam This application actually solves the issue (temporarily), but creates new ones: If I use the application to flip the video feed, Skype video call cease to work. This application doesn't save the settings, at least I wasn't able to find any way to save the settings I've used to flip the video feed. A computer restart brings all back to how it was, video feed upside down and if the application is still installed, Skype continues to fail on video calls. Regedit I've searched thru Windows Registry Editor as to find any reference to the webcam settings, hopping to find a key with the Flip parameter, since it's up to the driver to flip the image (by what I could ascertain from this problem). Couldn't find any reference to such settings, either they actually don't exist within the Windows Registry or they use some weird name that I could think off. System Configuration I was able to access the webcam system settings from the Windows Device Manager, but the tab that actually has the Image Rotation setting is always disabled. The same goes for the settings available from the Skype webcam options (that essentially is presenting the same settings as Windows Device Manager, just within a custom Skype pop-up). Question: How can I flip the video feed from the laptop's built-in webcam, as to properly see and broadcast the video?

  • All wireless networks suddenly disappear every once in a while

    - by snakile
    Lately, about every 15-60 minutes, my wireless internet connection disappears. When it does I can't find any other wireless network, though such networks exist. Only after rebooting the system, it goes back to normal and finds wireless networks, but only for a while. 15-60 minutes later it's disconnected again, not finding any wireless network. I'm using Windows 7 on Lenovo Thinkpad X201s. What could it be?

  • Extracting a SQLCLR assembly

    - by Ed Leighton-Dick
    One of our in-house applications has a SQLCLR assembly which is currently experiencing problems. The developer is having problems recreating the issue using the version that is stored in our source control system, so he suspects that some code may have been released that was not uploaded to source control. Is there a way to extract a SQLCLR assembly into a .dll file so that he can reverse engineer it for analysis?

  • JBoss naming service port conflict

    - by Kramer
    I am having trouble getting JBoss started. I am running JBoss 5.1.0 on Mac OSX (yes, I know it is an old version, but that’s what the application is certified on for now). I am using Apple’s JVM 1.6.0_37. I get the following error when trying to use JBoss (there are some more exceptions, but these are the first few): Error installing to Start: name=jboss:service=Naming state=Create mode=Manual requiredState=Installed java.rmi.server.ExportException: Port already in use: 1098; nested exception is: java.net.BindException: Can't assign requested address at sun.rmi.transport.tcp.TCPTransport.listen(TCPTransport.java:310) at sun.rmi.transport.tcp.TCPTransport.exportObject(TCPTransport.java:218) Caused by: java.net.BindException: Can't assign requested address at java.net.PlainSocketImpl.socketBind(Native Method) at java.net.PlainSocketImpl.bind(PlainSocketImpl.java:383) 16:57:15,596 ERROR [AbstractKernelController] Error installing to Real: name=vfsfile:/Users/home/server/jboss-5.1.0.GA/server/myserver/conf/jboss-service.xml state=PreReal mode=Manual requiredState=Real org.jboss.deployers.spi.DeploymentException: Error deploying: jboss:service=Naming at org.jboss.deployers.spi.DeploymentException.rethrowAsDeploymentException(DeploymentException.java:49) at org.jboss.system.deployers.ServiceDeployer.deploy(ServiceDeployer.java:118) at org.jboss.system.deployers.ServiceDeployer.deploy(ServiceDeployer.java:46) Caused by: java.rmi.server.ExportException: Port already in use: 1098; nested exception is: java.net.BindException: Can't assign requested address at sun.rmi.transport.tcp.TCPTransport.listen(TCPTransport.java:310) Caused by: java.net.BindException: Can't assign requested address at java.net.PlainSocketImpl.socketBind(Native Method) Now I know what you are thinking, that I am running something that conflicts with that port, but I have used lsof and there is nothing listed on that port. I have tried changing the port in conf/bindingservice.beans/META-INF/bindings-jboss-beans.xml: <bean class="org.jboss.services.binding.ServiceBindingMetadata"> <property name="serviceName">jboss:service=Naming</property> <property name="bindingName">RmiPort</property> <property name="port">5098</property> <property name="description">Socket Naming service uses to receive RMI requests from client proxies</property> </bean> Unfortunately, I then get the name errors with the new port number. I also installed a network monitoring tool on my box and it doesn't look like any ports are being opened when I start jboss, but it is possible, that the tool might be missing a port that is opened and then closed quickly. Any ideas what could be the problem or how to fix it?

  • Can't see any entries on "File Types" tab on Windows 7's Desktop Search

    - by Mick
    For some reason, Windows Desktop Search (included with Windows 7.0) now no longer shows any file types on the "Advanced Options" dialog box. Any ideas on how to fix this? WDS claims to be indexing...but I'm not sure what it's actually indexing right now. I should also add that when I try to add a file type, nothing shows up or is ever actually added. If I login as a different user on the same system, everything appears normally.

  • How to use Git over multiple similar systems

    - by Spidfire
    I have a system I need to duplicate over several systems and make minor changes like change less/css variables and configuration files. Is there a best practice for these kind of problems? I currently do: git clone repo cp ../default/config.js config.js ... for several files or should I create different branches of the same repo or should I create an repo for the changes? It is currently doable but it will get annoying if I get more than 5 similar systems.
