  • Can't ping devices by IP address for devices allocated IPs by DHCP

    - by GiddyUpHorsey
    I have a home network with a Trendnet wireless router and a Windows Domain. The Domain Controller/DNS server is a Windows 2000 Server and is configured to forward queries to DNS servers provided by the ISP. The router provides DHCP and is configured with the Windows 2000 Server as the DNS server. The network has been set up for a couple of years and usually works fine. When I connect iPhones to the network over WiFi, the router can ping the iPhones through its browser based admin interface, but Windows machines that are part of the Windows Domain cannot. A laptop was connected to the network over WiFi that wasn't joined to the domain and it could see the iPhones. The router UI shows that the laptop has a reserved IP allocated via DHCP. All machines either have a static or DHCP allocated IP on the 192.168.0.* subnet. Router - 192.168.0.1 - Static - Wired Windows Domain Controller - 192.168.0.8 - Static - Virtual Windows 7 Workstation - 192.168.0.200 - DHCP Auto - Wired VMWare ESXi Host - 192.168.0.201 - Static? - Wired iPhone 1 - 192.168.0.202 - DHCP Auto - WiFi iPhone 2 - 192.168.0.203 - DHCP Auto - WiFi Windows Vista Laptop - 192.168.0.204 - DHCP Reserved - WiFi Using the Windows 7 machine (200), I try to ping each machine and the only DHCP machine that responds is itself. The other DHCP machines fail with Reply from 192.168.0.200: Destination host unreachable.. Using nslookup fails with *** domain.controller.name can't find 192.168.0.203: Non-existent domain. Using the Windows 2000 Domain Controller (8), I try to ping each machine and the only DHCP machine that responds is the Windows 7 machine (200). Pinging the other DHCP machines fails with Request timed out.. Using nslookup also fails with *** domain.controller.name can't find 192.168.0.203: Non-existent domain. Using the iPhone 2 (203), I try to ping (Network Ping Lite) the machines with static IP addresses and that works fine. When I try to ping the Windows 7 machine (200) it is unable to get a response. How do I configure the DNS server/Windows Domain/Router properly so that the Windows Domain machines can see the IPs allocated via DHCP?

  • How to disable the second partition without unmount it in Mac?

    - by bagusflyer
    I've installed OSX Yosemite in another partition in my Mac. But there is a problem. For example, I installed iBooks in both partition. When I right click one of my epub or pdf file, both iBooks are shown in my context menu. This is not what I want. What I want is to only allow the apps in Yosemite shown. Of course I can disable apps in my old Maverick partition by unmount the volume. But again this is not what I want because it will hide the partition when I boot my machine so that I can't boot up into my Maverick partition. Can anybody advise if there are any better ideas? Thanks

  • Samsung printer (ML-1640) margin problem

    - by Rytis
    I just got a new laser printer, Samsung ML-1640, and it has once again confirmed my experience that Samsung printers suck badly. The printer prints fine, except that the top margin is set at random, usually very small, cutting text on the top of page off. I tried updating firmware, getting new drivers, but nothing helped. I tried changing paper types, and it seemed that with the paper set as "plain" it was OK, but I just tried printing again after letting the printer rest for the night, and wasted 6 pages until I managed to print 2 boarding passes... Is there anything else I could try to resolve the issue?

  • Dual HDMI input - HD Video Capture Card

    - by Shivan Raptor
    Any suggestion for HD video capture card? Here is my requirements: I need 2 HDMI input for 2 HD Camera the signal captured will be encoded with Adobe Live Encoder (does it support dual input sources? I do not require mixing of 2 sources) the encoding format will be H.264 (720p), then will be sent to Adobe Flash Media Interactive Server for LIVE broadcasting. http://www.blackmagic-design.com/products/intensity/ I found the one above online, but I am not sure about its performance, and it has only 1 HDMI input. If I plug 2 of them into my workstation, will it conflict with each other?

  • Change Gnome-Panel profile at startup according to number of displays

    - by ifischer
    I'm running Ubuntu 10.04 on a Laptop. I have a startup script which enables external displays, if they are connected. It runs at GDM startup, configured in /etc/gdm/Init/Default. When i'm running without external displays, Gnome should use 2 Panels. When i'm using 2 external displays, Gnome should add an additional Panel to the second display. But this should of course be removed again if i detach the external displays (and restart). Can i configure this use case by using Gnome Panel-profiles? I read that there is a startup option "--profile" for gnome-panel, but i don't know how and where i could switch the profile, especially because this has to be done after recognizing the number of displays. Or can i add a general Gnome profile and switch between those profiles somehow to achieve this behavior?

  • Advice needed for a home network setup (hardware & software) to handle many clients and potentially heavy traffic

    - by posdef
    I have recently decided to re-structure the home network of our flatshare here. Here's a quick outline of the situation. I envision to have the following 4 devices connected to the router via cable: Xbox 360 IP phone Printer QNAP server (Web, File and Multimedia) We are three people living here, so on top of that there will be to 5-6 computers/mobile devices connecting as wireless clients. My goal is to be able to transfer files (when needed) between the computer and the Multimedia server, which I can reach via 360 and play on the TV. I also would like to keep a high level of security; right now I have the encryption on WPA2 and MAC filtering. I don't believe the web server will get heavy traffic, though I would like to have it responsive. Likewise, I don't have a habit of downloading via torrent etc, but I greatly appreciate my network being responsive and fast, especially when I am browsing or streaming high quality media. Now my questions are: is this setup feasible? smart? efficient? can this be improved somehow? my current router (D-Link DI624) and the previous one (DI-524) used to have spontaneous drops in network, which I find highly irritating. I don't believe in my router, especially now that it completely crashed when I was test-running the setup by transferring a large media file to server while xbox was playing music from the server, and two computers browsing the net. Do I need to get new hardware, if so, any recommendations for a reliable and fast router?

  • Converting dynamic to basic disk

    - by Josip Medved
    I converted basic disk to dynamic on my laptop. However, now I cannot install Windows 7 on another partition. I just get message that installing them on dynamic disk is not supported. Is there a way to convert dynamic disk to basic without losing data on already existing partition?

  • A PDF viewer for large margins in fullscreen

    - by jmn
    I am looking for a way to pleasantly read PDF files on my widescreen (22" 1680x1050) monitor. My problem with all pdf the PDF-viewer applications I have tried is that they do not handle wide and high margins well. If I go to fullscreen mode in my viewer and zoom in so that the extra margins are cropped, I can view the pages nicely, the annoyance however is that I have to reposition the pages every time I navigate to another page. I am sure there must be a way to make a PDF viewer that can solve this problem and perhaps there is one you know of? I am aware of something called PDF Reflow in Acrobat Reader but that only works with certain specific (tagged) files. I want a PDF viewer with a smarter zoom/next page function or an automatic margin-crop function. Is there such a thing?

  • Android - Redirect sending of SMS message

    - by Donal Rafferty
    I currently use a ContentObserver to listen for changes in the SMS ContentProvider and tell my application whether a message has been sent or received. Upon getting notification that a message is being sent I would like to present the user the option to send that SMS normally over GSM/CDMA or if connected to Wifi to send the SMS over an ip connection. I am aware of how to present my own application as an option to create and send an SMS when a user clicks on a contacts information and "Send SMS" but this is not what I want. I want the user to be able to use the native or a 3rd party SMS application and when they try to send an SMS present them with a dialog screen giving them the option to send the SMS in whichever direction they want. So is it possible that once I get notified an SMS is being sent to pause it, allow the user to pick the desired route to send it and then change the sms from being sent over GSM/CDMA to being sent using a protocol over IP if required?

  • Laptop HDD failure imminent?

    - by Andrei Rinea
    I have an HP Compaq 615 laptop with an 160 GB 7200 rpm HDD. Hasn't been dropped or shaken, in fact it almost always stayed on my desk. I've treated it as nice as I could. The other day, however, my OS froze and I could hear a repeated clink-clink-clink coming from the HDD zone of the laptop. I had to switch off hardware-ly the laptop and re-start it. It worked very well after, including now. However I backed up immediately the core data on my USB drive and ordered an external USB HDD for periodic backups. Will it die soon or it was just a "blip"?

  • How to cope with runaway Flash plugin in Google Chrome browser?

    - by Norman Ramsey
    I'm using Google Chrome for Linux, version 5.0.307.11 (Official Build 39572) beta with the Linux Flash plugin version 10.0 r32. Quite often, the Flash plugin goes wild and pegs the CPU with about 95% usage. Laptop gets hot, battery drains. I can diagnose the problem with Chrome's little process monitor (shift-Esc), and I can even kill the plugin, but then when I actually want to use Flash on a page, I can't find a way to restart the plugin; I have to exit and restart Chrome, which with 30 tabs open is a huge hit. Does anyone know what causes this problem? Does anyone have a better workaround (or heaven forfend, a fix)? [I struct out both with search and with Google's help site for Chrome.]

  • What is the proper definition of software?

    - by studiohack23
    I sometimes see web based applications (eg Avairy, Google Docs) labeled as "software". Is this the true meaning of software? Isn't it supposed to mean applications that run natively on an OS, such as Photoshop or Outlook? Or does it mean ALL applications whether native or web-based?

  • Configuring WPA WiFi in Ubuntu 10.10

    - by sma
    I am trying to configure my wireless network on my laptop running Ubuntu 10.10 and am having a bit of difficulty. I am a complete Linux newb, but want to learn it, hence the reason I'm trying to set this up. Here's the vitals: It is a Gateway 600 YG2 laptop. It was previously running Windows XP, but I installed Ubuntu 10.10 in place of it (not a dual boot, I removed XP altogether). I have an old wireless card that I'm trying to resurrect. I haven't really used the card in a couple years, but it seems to still work, I just can't connect to my home's wireless network. The card is a Linksys WPC11 v2.5. When I plug it in, Ubuntu recognizes the network, but won't connect to it. My home network uses WPA encryption and the only connection type that Ubuntu's network manager is giving me is WEP and then it asks for a key -- I have no idea what that key should be. So, basically, I'm asking, is there a way I can instead connect through WPA? I've tried creating a new connection in network manager, but that won't work, it keeps falling back to the WEP connection and asking me for a key. I have tried to install the XP driver using ndiswrapper but I don't know if that's working or not. Is there a way to tell if: A) the card is working as it should B) the correct drivers are installed (again, I installed the XP one using ndiswrapper NET8180.INF, but I'm not sure what to do next) Any help would be appreciated. Thank you.

  • VPS IP redirects to website instead of the IP directory? CentOs 6

    - by Travis
    So before I started putting websites on my VPS, I could access the IP directly and it would access the html folder in the /var/www/ area. But ever since I placed websites on the VPS, I can no longer access that HTML folder, it goes to the first domain I have listed on the httpd.conf file. Is there a way I can make the IP its self look like a website in the httpd conf file? I tried to construct it like the other websites but httpd would stop working.

  • Not receiving bounced emails from PHPList

    - by user1780242
    I am sending a test campaign to my own address and to a fictitious nonsense address and I am receiving the email at my account but I am not receiving any bounces. My settings in the config.php file are: $message_envelope = '[email protected]'; $bounce_protocol = 'pop'; $bounce_mailbox_host = 'localhost'; $bounce_mailbox_user = '[email protected]'; $bounce_mailbox_password = 'XXXXXX'; What's the next step in figuring out the problem? I also tried both variations of the following: $bounce_mailbox_port = "110/pop3/notls"; #$bounce_mailbox_port = "110/pop3"; I am running a Godaddy Centos 6 VPS and Plesk 11.

  • Finding trends in multi-category data in Excel

    - by Miral
    I have an Excel spreadsheet that contains hundreds of rows of data that each represent a single sample in a larger population. Each row is divided into three columns that contain frequency counts of a specific type of thing. Together the three columns summed on a single row represent 100%, though each row will sum to a different value. What I'm most interested in are the proportions of each of these types (ie. percentages of each column relative to the sum of the three columns). I can easily calculate this on a per-row basis, but what I'm really interested in is trying to find an overall trend from the entire population. I don't really spend much time doing data analysis so the only thing I can think of trying is to create those percentage columns and then average them, but I'm sure there must be a better way to visualise this.

  • How to send Windows key over VNC to Linux from Windows?

    - by MJBoa
    Alright, so I'm running Linux with AwesomeWM on my home machine. I'm running x11vnc on that machine and I want to connect to it from a windows machine. So it suffices to say that I need the Windows key for my home machine to function. I really like TightVNC, but I have found that only RealVNC is able to send the Windows key presses that I need. My problem is that RealVNC is sorely lacking customization and I feel it's inferior to TightVNC and unusable. I know that Ctrl-Esc sends the windows key press in Tight but then I can't use it as a modifier key. Useless. Anyone have any ideas? I don't think it's a server issue since I've tried Tightvnc server on the linux machine and it still doesn't work, at least in TightVNC. It works with Real anyway. Oh and UltraVNC doesn't work either.

  • If I split my harddrive, will a system restore delete it?

    - by AoiHana
    I split my 1TB HD from C drive and called it A. I put some files there to back up. I have now come to a point where I need to run a system restore with the discs that came with my computer. If I do a system restore and wipe C drive clean, will I lose the part of the hard drive that I split or will it remain intact and my files uncorrupted? This is a partition I created with windows myself, and dragged files over to it. Thanks!

  • Using Windows 7 drivers in Windows Server 2008 R2

    - by Robert Koritnik
    Maybe I should post this to http://www.serverfault.com. Windows 7 comes with all sorts of signed drivers so there's high probability that all drivers for your machine will be installed during system setup. On the other hand Windows Server 2008 doesn't event though it's practically the same OS when it comes to drivers. But I know that this has a very good reason. It's a server product, not a desktop one. But the thing is that many power users and developers use server OS on their workstations which are normally desktop machines and would need Windows 7 driver spectrum... Question I know I've been reading about some trick on the internet that first installed Windows 7 on the machine, than do something to get either all Windows 7 driver collection or just those installed, and then install Windows Server 2008 and use those drivers. The thing is: I can't seem to find these instructions on the internet any more. If anybody knows where these are please provide the link for the rest of us.
