  • How to route traffic from a subnet 10.0.0.x to a network 200.208.88.17

    - by Guilherme Longo
    I have the following configuration Router : IP: 200.208.88.17 (Internet) MASK: 255.255.255.40 Server 2003 : IP: 10.0.0.1 (with dhcp server ativated) dhcp scope: 10.0.0.11 - 10.0.0.254 MASK: 255.255.255.0 clients : IP: 10.0.0.11 - 10.0.0.254 MASK: 255.255.255.0 At this point I have all computer set-up in one switch. All clients are receiving ip´s from the dhcp server. I need to enable the internet in every client. I am not sure how to route the traffic from the clients to the router that is providing internet access. Could you please point me to the right direction?

  • Windows 7 / Media Center lock problem

    - by ICTdesk.net
    Hi, we have a Win7 with Media Center that is connected to a large screen. It displays a corporate slideshow near the coffeemachine. When the computer is started it automatically logs in and starts the slideshow. The problem is that on irregular time intervals (once a day, some days not) the slideshow stops and it switches to the login screen and shows which user is logged on. We don't know why this is happening. We first thought someone on the network was trying to open RDC connection to the machine, because it is the same sympthon like when you take over a machine by RDC with a different user, but nobody is doing that. Screensaver is disabled, energy settings "always on" Anybody ideas why this is happening?

  • How to get OpenSSH to use ksshaskpass under KDE?

    - by Guss
    When using a GNOME desktop on Ubuntu, if I use OpenSSH client to connect to another computer (running from the gnome-terminal), I get a single graphic popup asking for my private key's pass-phrase. After that I no longer need to enter my pass-phrase as it is cached by the SSH agent. Under KDE it doesn't work like that - when I start ssh from konsole, I get a text prompt for my pass-phrase every single time, even though ssh-agent is running. If I run ssh-add from the terminal then I can enter my pass-phrase on the terminal and it will be stored by ssh-agent and I won't get any more pass-phrase prompts, while if I run ssh-add the KRunner graphical command line ("Run" dialog) then I get a graphical prompt with the same behavior. The problem is I have to remember running ssh-add every time I log in to the desktop. How can I get ssh to behave under KDE, the same as it does on GNOME - the first time the pass-phrase is needed, pop up a graphical dialog and store the pass-phrase in the agent. I've installed ksshaskpass, but that didn't change anything.

  • I need something substantial to do [on hold]

    - by Christian Delapena
    I'm a 19 year old computer geek who was recently exposed to Linux. I know quite a bit of it now and would like to do something substantial with it. I've visited websites like openhatch where you can get started on opensource projects but I'm more interested in something Linux-specific like hosting a website or tracking some important operation. Maybe running a script that will give me data on something important. I don't know. I'm essentially bored and I want to put my knowledge and love of Linux to good use. Someone please point me in the right direction.

  • Ubuntu web site hosting & free ,tk domain

    - by user5819
    Hello, I am sort of new to web hosting so sorry if I ask bad questions. I have a pc that runs ubuntu I instaled apache and now I host a web site, but I need a domain name so I found out .tk is free. The site works when typing 192.168.1.x in the browser(x= a number) but in dot.tk when I register in ip it whats one that look like 79.117.x.x so thats where I get stuck, I think I managed to make my ip address static but it still looks like 192.168.1.x and I can't put that in because it says: " This IP address is not valid". Why must it have the ip address that looks like 79.117.x.x and won't work with the internal static one and how can I do to host my site with a .tk domain name ? PS: I'm using a cisco router that's connected with computer via a cable.

  • Dell Vostro 1000 w/fresh XP Pro installation running very slow

    - by ssvarc
    I'm working on a Dell Vostro 1000 laptop. It was running slowly and hanging, antivirus scans turned up nothing and the same with the Dell diagnostics (DFT hung - but Dell's diagnostics gave the HD a pass) so I imaged the HD and installed XP Pro on it. The laptop is still slow! (It takes a noticeable delay to enter words into the Google search box in IE and the computer hangs every time it enters the XP screensaver.) What are the likely possibilities at this point and how would I go about checking for them?

  • Are programmers getting lazier and less competent

    - by Skeith
    I started programming in C++ at uni and loved it. In the next term we changed to VB6 and I hated it. I could not tell what was going on, you drag a button to a form and the ide writes the code for you. While I hated the way VB functioned I cannot argue that it was faster and easier than doing the same thing in C++ so i can see why it is a popular language. Now I am not calling VB developers lazy in just saying it easier than C++ and I have noticed that a lot of newer languages are following this trend such a C#. This leads me to think that as more business want quick results more people will program like this and sooner or later there will be no such thing as what we call programming now. Future programmers will tell the computer what they want and the compiler will write the program for them like in star trek. Is this just an under informed opinion of a junior programmer or are programmers getting lazier and less competent in general? EDIT: A lot of answers say why re invent the wheel and I agree with this but when there are wheels available people are not bothering to learn how to make the wheel. I can google how to do pretty much anything in any language and half the languages do so much for you when it come to debugging they have no idea what there code does of how to fix the error. That's how I cam up with the theory that programmers are becoming lazier and less competent as no one cares how stuff works just that it does until it does not.

  • Get cryptic error when trying to create a snapshot of any of my VMs

    - by Zolt
    I'm using Oracle VM VirtualBox. I have 6 VMs that I've imported. When I click on an individual VM, and then click the camera image (or Ctrl+Shift+S) to take a snapshot, the snapshot process fails and VirtualBox gives the following error: Failed to create a snapshot of the virtual machine vmName. Details: Result Code: VBOX_E_IPRT_ERROR (0x80BB0005) This happens not only for one of my VMs, but all of them, if I try to take a snapshot of each one separately, one at a time. My computer is a Windows 7 machine. I have 200 GB free on my hard drive, and I see no reason why the error should occur. I can import VMs, run them, and clone then without any problems. Can anyone tell me what to do to fix the issue?

  • How to diagnose very slow pagefile

    - by svick
    Quite often, one of the applications I use freezes (“does not respond”) for a while, in extreme cases for few minutes. This happens especially when when switching apps. During this time, the HDD light flashes constantly and perfmon show that HDD is used 100% of the time (OTOH, CPU isn't) and that pagefile is being read (which is to be expected when switching apps), but at a very slow rate. When I sort the disk table in perfmon by read or write, the file read and wrote the most is the pagefile, but it's still quite low rate (I don't remember the numbers). How can I diagnose what's causing this? I use Windows Vista, and the computer is quite ordinary two years old laptop.

  • how to connect virtual box os and local machine

    - by Nrew
    This question is in connection to this question asked by a user before: http://superuser.com/questions/73470/virtualbox-vdi-file-to-vmware On how to convert vdi to vmdk or vmx using vmware converter. How do I connect the windows xp that is in virtual box to the local computer (windows 7) in a network. Because I got this error while I tried following this instruction: Give the IP address, username and password of the remote machine that you would like to convert and then hit next I got this error in vmware converter: Unable to connect the specified host 10.0.2.15 which is the ip address of the xp machine inside virtual box. It also said that there is a network configuration problem. And when I inputted the ip address from whatismyip.com which should be the same as the ip address on local machine. I didn't get the previous error but I got another one, it said that: insufficient permissions to connect to "ip address" What solution can you suggest for this problem?

  • SharePoint 2010 not seeing Active Directory users

    - by user117927
    I'm pretty new to Active Directory and SharePoint but I was given to understand they are supposed to play well together. Now I have successfully set up AD with multiple user accounts that work on any member computer. I have also successfully installed SharePoint 2010 Server on an AD machine. Both the AD server and SharePoint servers are on separate machines (VMs running on ESXi to be precise). I can only log on with user accounts I create on the local server. Furthermore the user browser thing for adding users will only see local users. I've followed the advice here http://technet.microsoft.com/en-us/library/cc262350.aspx#section2 for Classic authentication and also NTLM claims based authentication but to no avail. Is there something fundamental I am getting wrong here? I'd be really thankful for any help you can lend me; I've been googling and scratching my head for a couple of days now. P

  • Driver choice for addressing ubuntu wireless card issues

    - by Holly
    Hello, this should be a relatively simple question. I'm attempting to get my windows wireless card to work with ubuntu, booted from my portable hard drive. This is the guide I'm attempting to follow is on help.ubuntu.com, /community/WifiDocs/Driver/Ndiswrapper My wireless card is a Broadcom Corporation BCM4318 AirForce One 54g 802.11g Wireless LAN Controller. My computer is an HP Pavilion Entertainment dv5 notebook, which came with Vista 64. I would like confirmation about which of the drivers I should use. At this point, I'm leaning towards Broadcom BCM4318 HP Pavilion zv6000, but I thought it best to ask advice before taking action. The drivers I have to chose from are listed on this page http://sourceforge.net/apps/mediawiki/ndiswrapper/index.php?title=Category:Broadcom Thanks! Holly

  • Windows 7 offline files - work temporarily offline even if network connection works

    - by Robert
    Sometimes I am connected via VPN to a network containing the server where files are stored which are cached by Windows offline files feature. Sometimes the connection works good and working this way is not a problem - on other times working is quite a pain because of high latency when working with the files in the Windows explorer. Is there an interactive way how a user (with admin permissions) can temporary suspend online usage of offline files? I already activated the "Transparent caching" group policy feature (Computer Configuration Policies Administrative Templates Networks Offline Files) with a network latency of 200msec but from my experience even if I get ping times to the file server of less than 40msec online usage is quite tenacious. Setting low latency times at this point causes the offline files often to toggle which makes problems with some applications working with several files and requires them to be consistent (like SVN client).

  • Where did this incorrect cached DNS lookup come from?

    - by Stephen Jennings
    Somehow, I've been having a chronic issue where my computer will get an invalid DNS lookup in its cache for either of the two Exchange servers I use from Mail.app. My workplace runs one of the Exchange servers and I run the other (they are totally unrelated, hosted by different companies, etc.). The problem manifests as a certificate domain error. When it happens, I can run nslookup mail.mydomain.com and I see the incorrect IP address (usually owned by either Apple or Akamai), but if I run nslookup mail.mydomain.com 8.8.8.8, I get the correct address. My real quest is to find out why this keeps happening, and to do that, I'd like to know which server is supplying me this bad DNS entry. Is there a way to check my DNS cache to see where this bad lookup came from?

  • Very long DNS lookups inside my network

    - by Nuno Cordeiro
    Ever since I installed DD-WRT (v24-sp2 08/07/10 std-usb-ftp) on my router (RT-N16), my browsing got substantially slower. Using FirePHP I figured out that it's being caused by VERY long DNS lookups (~30 seconds). When the domain name was very recently accessed then speed is very good. I tried changing DNS on the computer and I tried messing around with the options on DD-WRT. I have tried to configure the router with Google DNS and/or OpenDNS. My current DNS output after using ipconfig -all is: 192.168.1.1 208.67.220.220 8.8.8.8 208.67.222.222 Can someone help me debug and solve this problem? I'd like to snoop the requests themselves. How can I know which DNS requests are being sent and which are failing/succeeding? Note: I don't expect this to be relevant but my router is connected to the internet through an ONT.

  • SQL SERVER – A Cool Trick – Restoring the Default SQL Server Management Studio – SSMS

    - by pinaldave
    “I do not know where my windows went!” “I just closed my object explorer and now I cannot find it.” “How do I get my original windows layout back in SQL Server Management Studio?” “How do I get the window which was there in left side back again?” Since last 2-3 years, every single day I receive more than 5 emails on SSMS and its layout. For the beginners it is very common to get confused when they attempt to change SQL Server Management Studio’s windows layout. They often change the layout and are not able to get the original layout back. Often people do not change the layout whole of their life, leading to uncomfortable feeling when they go to another’s computer where the windows are differently placed. Today’s blog post is dedicated all the beginners in SQL Server. It is extremely simple to reset the SSMS layout to default layout. The default layout involves 2 major things 1) Object Explorer on left side 2) Query Windows on right side (80% screen estate). Personally I am so used to this as well that if there is any other changes in the same, I do not enjoy working on the environment. Well, the solution to rest the SSMS layout is very simple. One can do it in split seconds.  To restore the default configuration, on the Window menu, click Reset Window Layout. Have you ever used this feature? Do you feel uncomfortable when SSMS layout is not in default state? How do you address this situation?

  • Using AHK PostMessage to send WM_WININICHANGE to Program Manager

    - by SaintWacko
    I've written a script which updates an environment variable, but I need to tell Program Manager to update the computer's programs with this new information. I was given this as the API call that is made within another program to cause this: ::SendMessage(::FindWindow("Progman", NULL), WM_WININICHANGE, 0L, (LPARAM)"Environment"); I am attempting to translate this into an AutoHotKey PostMessage call, but I'm doing something wrong, as it isn't working. Here's where I've gotten so far: PostMessage, 0x1A,, (LPARAM)"Environment", "Program Manager" Here are the AHK resources I've been looking at to do this: List of Windows Messages Send Messages to a Window or Its Controls PostMessage / SendMessage And here are the resources that I used to figure out the original API call: SendMessage function WM_WININICHANGE message Can anyone help me figure out what I'm doing wrong?

  • Citrix ICA Client on Mac shift key doesn't work as expected.

    - by brianegge
    When I'm connected to a Windows XP computer from my Mac OS X 10.6 using the Citrix ICA Client, it seems that the shift key only works for the first letter typed after pressing shift. In order to type multiple uppercase letters, like ICA, I must either press caps lock, or press and release shift before each character. I've tried switching between standard and enhanced keyboard, as well as the 'Send Special Keys Unchanged' option, but none of these seem to affect the issue. The problem doesn't occur when I switch from the Citrix window to a regular Mac window.

  • Ubuntu 12.04 boot hangs with a black screen before grub menu after upgrade (gma500_gfx driver)

    - by Eric van der Vlist
    I am using Ubuntu on a fit-pc2 specifications and after upgrading from 10.04 to 12.04 I get a black screen at boot time (before displaying the grub menu) and the computer hangs with no disk activity. I have managed to boot Ubuntu 12.04 on a live USB key but had to add the following boot options to do so: console=tty1 or console=text acpi=off noapic nomodeset Using boot-repair, I have tried to add these options to /etc/default/grub (see this pastie log for instance) but I haven't been able to fix the black screen issue. I have tried many other things such as the workarounds mentioned on the web for PSB-GFX_drivers without any success and also to uncomment GRUB_TERMINAL=console with the result of getting a No video mode activated error. During these tests, I have managed to break /boot/grub/grub.cfg and could then hit grub in command line. This gave me the chance to check that I can boot without problem if I type: grub> set root=(hd0,1) grub> linux /vmlinuz root=/dev/sda1 ro acpi=off noapic nomodeset console=tty1 grub> initrd /initrd.img grub> boot How can I tell grub to use these options?

  • Controlling an amplifier power supply from Squeezebox/SqueezeCenter

    - by teabot
    I have a Squeezebox that is connected to an amplifier. I'd like the amplifier to switch on/off whenever the Squeezebox is powered on/off. I don't mind writing some plugin code to SqueezeCenter to do this but in hardware terms I am looking for off-the-shelf components. I imagine that I need some kind of Ethernet controlled power outlet. I have looked at X10 (I can't bring myself to link to their terrible site), but their product range seems extremely confused and it looks as though I'd have to use both RF and comms-over-mains to implement a computer controlled socket. Does anyone have any alternative suggestions? Note: Any components should be available and certified for use in the UK.

  • Java 6.0 Virtual Machine re-caches application on every load

    - by David Neale
    I have a Java application which is loaded and cached by the JRE and for most users it only needs to cache once unless the application software has changed. However, I have one computer that caches the entire application every time they load it. It is not the version of the JRE, I have that running on other machines. It also works on this machine if logged in as a local admin, just not as a standard user. Does anybody have any ideas on what might be causing this?

  • Mouse for a lefty?

    - by Kyralessa
    As a programmer, I'm fairly particular about my keyboard and mouse. One thing I've only recently noticed is that the mice I tend to prefer don't work well for my five-year-old. He's left-handed, but ends up mousing with his right hand on the computer because (a) that's where the mouse is, and (b) most mice are designed for right-handed people anyway. So, a couple of questions: If you're left-handed and you mouse with your left hand, do you have any recommendations on good mice? If you have a lefty in your household (whether or not it's you), is there an easy way to swap settings between left-handed and right-handed mouse buttons? One way is Control Panel Mouse Check the box on the first tab OK. Do you know of anything faster? Or, better yet, what I'd really like is a way to reverse those settings on only one particular mouse, which would be designated as my son's mouse.

  • Connecting my XBOX 360 to home network

    - by patrick
    I am trying to set up my XBOX 360 as a Windows Media Center Extender. I input the code as shown on the XBOX screen, but I get the error message: "Cannot Set Up Extender." This means that the Extender was found (there's a separate error msg for extender not found), however it can't be set up. Windows points me to this page which tells me to change my router settings to enable multicast and UPnP. My router doesn't have those specific settings but I did open all ports for the XBOX. What is odd about this problem is that it did work, then I restarted my computer and didn't change any settings, and now it doesn't work. I guess something did change, but I can't figure out anything else to try after opening all ports. I'm running Windows 7 and the router is fairly recent (I bought it about six months ago) so it should be able to handle this. The router firmware is up to date.
