  • BIND DNS server (Windows) - Unable to access my local domain from other computers on LAN

    - by Ricardo Saraiva
    I have a BIND DNS server running on my Windows 7 development machine and I'm serving pages with WAMPSERVER. My ideia is to develop some tools (in PHP) for my intranet at work and I want them to be accessible via LAN in this format: http://tools.mycompany.com I've already placed BIND and I can access http://tools.mycompany.com on the machine that holds BIND server, but I cannot access it from other LAN computers. I've done the following on my router: defined static IP's for all LAN computers set Port Forwarding to my server (remember: it serves DNS and Web pages) set DNS server configuration to point to my LAN server On LAN computers, I went to Local Area Network properties and also changed the DNS server IP in order to point to my local DNS server. If it helps, here is my named.conf file: options { directory "c:\windows\SysWOW64\dns\etc"; forwarders {127.0.0.1; 8.8.8.8; 8.8.4.4;}; pid-file "run\named.pid"; allow-transfer { none; }; recursion no; }; logging{ channel my_log{ file "log\named.log" versions 3 size 2m; severity info; print-time yes; print-severity yes; print-category yes; }; category default{ my_log; }; }; zone "mycompany.com" IN { type master; file "zones\db.mycompany.com.txt"; allow-transfer { none; }; }; key "rndc-key" { algorithm hmac-md5; secret "qfApxn0NxXiaacFHpI86Rg=="; }; controls { inet 127.0.0.1 port 953 allow { 127.0.0.1; } keys { "rndc-key"; }; }; ...and a single zone I've defined - file db.mycompany.com.txt: $TTL 6h @ IN SOA tools.mycompany.com. hostmaster.mycompany.com. ( 2014042601 10800 3600 604800 86400 ) @ NS tools.mycompany.com. tools IN A 192.168.1.4 www IN A 192.168.1.4 On the file above 192.168.1.4 is the IP of the local machine inside my LAN. Can someone help me here? I need my web pages to be accessible from other computers inside my LAN using my custom domain name. I've tried on other computers and they can access my server via http://192.168.1.4/, but no able when using http://tools.mycompany.com . Please, consider the following: I'm completely new to BIND I have basic knowledge in Apache configuration Thanks a lot for your help.

  • Using multiple computers effectively

    - by Benjamin Oakes
    I have some extra (old) Macs and PCs around the house and a MacBook that's sometimes overworked. I'm looking for tips on using multiple computers effectively. Basically, I'd like to add to the following list. Here's what I'm using so far: Teleport: lets you use a single mouse and keyboard to control several Macs, like Synergy Built-in file sharing: lets me run programs on another Mac, but only maintain one copy of the data Bazaar: distributed version control Mail.app, Thunderbird, etc.: IMAP for my mail accounts TuneConnect: control iTunes on another Mac with a nice interface, using the library on my MacBook (if I choose it by pressing option at startup) over file sharing OmniFocus: syncs across computers pretty seamlessly Web browsing across computers VNC/Remote Desktop Running X-windows programs using ssh -Y hostname for headless operation (but they die when I sleep the connecting computer -- something like GNU screen would be ideal) Plain-old ssh with GNU screen Really, a better idea of what I do might be necessary. Generally though, I'd like to distribute tasks across more than one computer when possible, but not have much overhead in doing so. The perfect solution? An Xgrid-like program that pushes processing across multiple computers automatically and seamlessly (although that seems unlikely). Here's what I have, in case it makes a difference: MacBook (Dual 2.16 GHz, OS X 10.6.3) eMac (1.25 GHz, OS X 10.4.11, soon to be 10.5) Dell Dimension (800 MHz, some version of Ubuntu) -- no dedicated monitor PowerMac G3 (400 MHz, OS X 10.4.11) -- no dedicated monitor iMac G3 DV (400 MHz, OS X 10.4.11) -- currently in the kitchen for recipes, email, web browsing, music, movies (DVDs), etc. (Total, they cost me around $650, mostly for the MacBook. Freecycle is wonderful, just in case you haven't heard of it.) I'm really only using the MacBook and eMac at this point, but I'd like to push more onto it and possibly the PowerMac and Dell.

  • Everyone can access my Windows 7 Homegroup file shares - Even Windows XP computers

    - by Adrian Grigore
    I have 3 computers in my network, two running Windows 7 and one running Windows XP. I've set up a homegroup on both Windows 7 computers. Also, all computers are in the same Workgroup. The problem is that one of the Windows 7 computers makes all shares accessible to the entire Workgroup instead of just sharing to the Homegroup as it should be. I created the file share in Windows 7 via right-click in the explorer, then click on "Share For" - "Homegroup (Read/Write)" (translated from German, so the actual wording may be different). Also, when I look at the file sharing properties of that folder, Windows Explorer informs me that Users must have a valid account and password for this Computer to access drive shares. Unfortunately this is not true. Being in the same Workgroup is enough to get access. Homegroup restrictions work as expected on my other Windows 7 computer. When trying to browse those shares from the XP computer, I get a dialog asking for a login and password. What might cause homegroup restrictions to fail and how can I fix this?

  • Very strange networking problem in all computers in my house

    - by Anthony
    I have three computers in my house: One desktop (wired), and two laptops (wireless). I'm using Cox Communications (yes they suck), and yesterday they had a major outage. I know it was them because I called them up when I started losing connection to the internet. All the computers can connect just fine, but they don't have internet access. It just says "local only". The weird thing is, some of them work occasionally. For the first day my laptop was working perfectly, while all the other computers couldn't connect. Later on in the day it got reversed, and the desktop was the one with internet access. By the second day the problem on Cox's end was fixed, but we still had no access. I called them up and they reset my modem, and did the usual troubleshooting stuff. It never fixed the problem, but we found out that the problem had to do with conflicting IP addresses. My router was a Linksys WRT54G and it was about 5 years old. I figured it might have gotten damaged from the outage since it was so old, and now it's having trouble "fixing itself" and giving out the proper IP addresses. So I bought a new router, a Cisco Linksys E1000. I set everything up, and still the same problem. My computer has access right now (that's how I'm writing this), but no other computers seem to be able to get access. Is there possible damage to the modem? Can someone help me please? Sorry for this being so long.

  • Use Ubuntu’s Public Folder to Easily Share Files Between Computers

    - by Chris Hoffman
    You’ve probably noticed that Ubuntu comes with a Public folder in your home directory. This folder isn’t shared by default, but you can easily set up several different types of file-sharing to easily share files on your local network. This folder was originally meant for the Personal File Sharing tool, which is no longer included with Ubuntu by default. You can install the Personal File Sharing tool or use Ubuntu’s built-in file-sharing feature to share files. HTG Explains: What Is RSS and How Can I Benefit From Using It?

  • Creating natural environments that can run on lower end computers in Unity3D/C#

    - by Timothy Williams
    So, I'm starting work on a project soon that will require me to create realistic environments that can preferably run on PC's besides high quality ones. The goal is to get as real an environment as possible while still being easy(ish) to run. The only problem is I've NEVER done anything with 3D environments, making trees sway, grass move, lighting, etc. Can anyone give me any help? Perhaps describe how it's done? Link me to articles? I'm just looking to be pointed in the right direction, not for you to write the code for me. Any help at all would be greatly appreciated, I'm using Unity3D and C# as my language. Thanks, Tim.

  • Gnome indicator applet not showing same items on two computers

    - by EmmyS
    I have one computer running Lucid and another one that I recently upgraded to Maverick. Up until today, I was using AWN with Maverick, including their custom indicator applets. I've decided to switch back to the default gnome panels with dockbarx, but when I add the indicator applet to my panel, it's not displaying the same items as the applet on my Lucid machine. In particular, the network and Dropbox icons are not displaying. When I look at the About entry for the apps, Lucid shows version 0.3.7, whereas Maverick shows 0.4.6. Did they really remove the network information from the applet in Maverick, or do I need to do something to enable it? My network is very definitely connected, as I still have AWN running and can see the icon there. (A second question, although not particularly important: the applet doesn't inherit the transparency of the panel it's living on - any way to change that?)

  • Cannot ping any computers on LAN

    - by Timothy
    I havem't been able to find a straight forward answer on this yet. I'm hoping people here are able to help! Keep in mind that I'm a complete beginner at this - this is the first installation i've done for any LINUX systems ever so please keep that in mind when answering this question. We are a complete Windows shop, using nothing but Microsoft products but looking into the value of OpenStalk however have been having problems getting Ubuntu Server installed and speaking to the network. The machine is getting an IP address which is telling me that some sort of DHCP activity is working but I'm not able to ping any computer on our network as well as not able to connect to the internet. Every time I try to ping i'm getting; Destination Host Unreachable I've tried using modifying the resolv.conf file with our static details to match my Windows 7 machine still with no luck. Even tried disabling the firewall on Ubuntu Server 11 and no luck. Any ideas? Please let me know if there is any information you need from the server and I'll post up.

  • How to Use KeePass In Your Browser, Across Your Computers, and On Your Phone

    - by Chris Hoffman
    If you’re using a password manager and it’s not the cloud-based LastPass, it’s probably KeePass. KeePass is a completely open-source password manager that stores all your sensitive data locally. However, this means that it isn’t quite as well-integrated as other solutions. Want LastPass-style browser integration, the ability to synchronize your passwords and have them everywhere, and an app to access your passwords on your phone? You’ll have to string together your own system.

  • How to Run PowerShell Commands on Remote Computers

    - by Chris Hoffman
    PowerShell Remoting allows you to run individual PowerShell commands or access full PowerShell sessions on remote Windows systems. It’s similar to SSH for accessing remote terminals on other operating systems. PowerShell is locked-down by default, so you’ll have to enable PowerShell Remoting before using it. This setup process is a bit more complex if you’re using a workgroup – for example, on a home network — instead of a domain.

  • understanding computers [closed]

    - by Ashwin
    Possible Duplicate: Good resources to understand how a program interacts with machine hardware I don't know if this is the correct StackExchange site to ask this question. But I could not find any other. I want to understand how a computer works from the software level to the internal structure. For example what happens when I press a button on keyboard. The OS interprets it and then what changes happen in the flip-flops. How is an operating system written? If it is written using some programming language, then how is that interpreter written. At some point it has to come down to the hardware, right? I know to program in c, c++ and java. But after all these years I am still not sure about what is happening inside. I would be grateful to anyone who points me to to a link or a video that explains this to the deep.

  • 3D physics engine for accurate collision handling on desktop/laptop computers (non-console)

    - by Georges Oates Larsen
    What are your suggestions for a physics engine that satisfies the following criteria? Capable of calculating collisions between multiple concave mesh-based colliders Handles many collisions going on at once (for instance one mesh being wedged between two others, which themselves may be wedged between two meshes) Does not allow for collider passthrough, even at high speeds. For instance, if I am applying force to a programmatically hinged object that makes it spin, I do not want it to pass through another rigidbody that it collides with while spinning. I have this problem using PhysX As implied before, reacts well to hinged objects, preferably has its own implementation of a hinge, but I am willing to program my own. The important part is that it has some sort of interface that guarantees accurate collision tracking even when dealing with these things Platform independent -- runs on mac as well as PC, also not tied down to specific graphics cards I think that's the best way to explain what I am looking for. Basically, I need SUPER reliable collisions. Something that can't be accomplished with a simple ray casting approach that sends a ray from the last position of the object to the current position (as this object may be potentially large and colliding with small objects via rotation) Bonus points for also including an OPEN SOURCE engine.

  • Syncing apt-get installations between multiple computers

    - by Chris
    Is there a way to synchronize my installations (and removals) between multiple PCs? Preferably with dropbox - since I'm already using that to keep my files in sync. Edit: I thought of an alias for the apt-get install and apt-get remove commands that stores the parameters to a file (one for install, one for remove) and another command that reads all the entries in the file and executes the respective command. Is this an realistic approach?

  • Syncing between computers / batch download

    - by Eric
    I have synced files from two different devices. Now I want to copy to contents of the synced files to the other device. Using the web interface, it seems only possible to download one file at a time. Is there a way to setup automatic sync or to download all the files in a folder with one step? Thanks in advance for your time. I was using the web interface to ubuntu, but an answer for Ubuntu One would also be ok.

  • shutdown -i all computers in active directory domain

    - by Sihan Zheng
    I'm not sure if this is possible, but this is my goal: At the end of the day, I want to be able to turn off all the computers in the domain from a client. My account has sufficient privileges to shutdown any single computer remotely using shutdown -I, and I can RDP into any computer in the domain. However, is there an automated technique that does this? the computers in the domain are predictably named (computer1, computer2, etc), but than manipulating a list of 2000 computers in shutdown -I is pretty clumsy. Is there a way to shutdown every single computer in the domain from a single client? The domain server is windows 2003, and the clients all run windows xp thanks

  • Cloud Computing - Multiple Physical Computers, One Logical Computer

    - by Koobz
    I know that you can set up multiple virtual machines per physical computer. I'm wondering if it's possible to make multiple physical computers behave as one logical unit? Fundamentally the way I imagine it working is that you can throw 10 computers into a facility one day. You've got one client that requires the equivalent of two computers worth, and 100 others that eat up the remaining 8. As demands change you're just reallocating logical resources, maybe the 2 computer client now requires a third physical system. You just add it to the cloud, and don't worry about sharding the database, or migrating data over to a new server. Can it work this way? If yes, why would anyone ever do things like partition their database servers anymore? Just add more computing resources. You scale horizontally with the hardware, but your server appears to scale vertically. There's no need to modify your application's infrastructure to support multiple databases etc.
