  • Would a typical corporate firewall block a Java applet having the following behaviour

    - by auser
    I'm thinking of developing a proxy-like program to forward ports on a remote PC to a local PC (for example SSH). Assume that both local and remote PCs are running behind typical firewalls (i.e. consumer broadband router firewall, Windows firewall or corporate firewalls). The program will be a Java program which the user will run on both the remote and local PC. The remote client will periodically poll a central server to determine whether there are pending client connections. A session could be initiated as follows: The local client contacts the central server and request the current connection details for a specific remote client. The central server responds with the remote server's last received IP address and port. The next time the remote server polls the central server, the client's IP address and port are returned. The remote server initiates a connection to the local client using the IP address and port returned by the central server and listens for a response on a random port. The remote server will pass the value of the port it's listening on to central server. Goto 1, if client fails to connect to server. Would this work or will a typical firewall block the interactions.

  • Procedural object generation and unique identification

    - by 2080
    My question relates to procedural content generation and data management of the emerging objects in a database. I assume a networked game, with a server-client model. Unspecified objects in the game world are generated while the game is running with procedural algorithms (for example perlin noise). The players (/clients) can modify the properties of these objects, but have to notify the server of these changes. How could this communication address unique objects, so that both the server and the client know of which object they are speaking? Not only the inner properties of the objects can differ, but also visible, such as the position. When the player wants to select one of these objects the game has to find out the id - does anyone know which methods or algorithms can accomplish that?

  • Duplicate ping response when running Ubuntu as virtual machine (VMWare)

    - by Stonerain
    I have the following setup: My router - 192.168.0.1 My host computer (Windows 7) - 192.168.0.3 And Ubuntu is running as virtual machine on the host. VMWare network settings is Bridged mode. I've modified Ubuntu network settings in /etc/netowrk/interfaces, set the following config: iface eth0 inet static address 192.168.0.220 netmask 255.255.255.0 network 192.168.0.0 broadcast 192.168.0.255 gateway 192.168.0.1 Internet works correctly, I can install packages. But it gets weird if I try to ping something I get this: PING belpak.by (193.232.248.80) 56(84) bytes of data.

  • Google locking on Ubuntu

    - by user170534
    Problem I'm facing is that Google doesn't respond well timed to connection requests send from any browsers known to Linux. As far as I can tell, this was existent in Mint, which is Ubuntu based. I have no debug or guess about cause but I'm sure there are people with the same problem. ping of terminal is untouched but any other browser keeps unloaded, for example; google loads fine, I search for something. Then I decide to search for something else and ta daa: You gotta wait for 30 seconds for Google server to respond. I tried using google's public DNS without success. Flare the suggestions & ideas!?

  • Cannot use broadband in Kubuntu

    - by Amanz Linux
    I have 5 months of experience using ubuntu 10:10. And it is clear it is suitable for broadband use. For Kubuntu, I have thoroughly tried everything available, using the 10:10 Kubuntu CD that I have had for the last week. It is very appealing, but in the meantime I am unable to use broadband in Kubuntu. I've tried and tried, thinking that it was possible that the use of broadband in Kubuntu was the same as in Ubuntu, so I have attempted to use broadband just as I used it in ubuntu. But I have failed to successfully test the broadband. Kubuntu was much different from ubuntu. Can anyone help me solve this problem?

  • Other people's files showing up in rhythmbox

    - by Avery Boyer
    I have my computer connected to a college network, and right now files that belong to other individuals on campus are showing up under Shared in rhythmbox. This is driving me up the wall, I absolutely despise the idea that files are being thrown around on the network and that other people's s*** is showing up on my computer, and that they may be able to see my files as well. This is a very, very serious problem as far as I am concerned and I want to know how I can ensure that I am sharing nothing with the network in the way of files on my computer and that no one else's files are showing up on my computer.

  • Wifi is connected but internet not working?

    - by Philip
    I have a lenovo x230 running ubuntu 12.04lts. I've been using it just fine for a while, but all of a sudden the internet's stopped working. It's connected to the router just fine (I can see the antenna bars saying it's connected) but when I try to go to a webpage, it's just loading forever. I've tried the fix listed here (http://ubuntuforums.org/showthread.php?t=1985079) but it hasn't done anything (the instructions are a little confusing though). I'm booting windows 7 right now and the internet works just fine when I'm on windows, so I know it must be a problem with ubuntu. I haven't touched any network settings before this problem happened, and I've been using it just fine for months, so I don't know why I'm getting this problem all of a sudden. Oh and I haven't updated anything in a few weeks (you know when the update manager pops up every so often listing all the things there's an update for) so I know it's not some update that broke it.

  • How to merge multiple internet connections into one

    - by Luis Alvarado
    My PC has 2 wired cards. Both gigalan. It also has 2 wireless cards. One broadcom with proprietary drivers and ralink with open software (which works much better than broadcom). My cellphone can share its connection wirelessly to my PC. But I also have a wired connection. So I have multiple connections that I can use to have internet. How can I merge 2 or more connections together and balance them to enjoy one unified internet experience that it is the sum of all internet connections connected to it. For example if I have an internet connection that offers 1024KB/Sec and another that offers 512KB/Sec and one small one that offers 128KB/Sec, after load balancing and merging all connections, I could download at a speed of 1664KB/Sec using all 3 internet connections as one for example. This question has always intrigued me.

  • Best way to cache apt downloads on a LAN?

    - by Ken Simon
    I have multiple Ubuntu machines at home and a pretty slow internet connection, and sometimes multiple machines need to be updated at once (especially during new Ubuntu releases.) Is there a way where only one of my machines needs to download the packages, and the other machines can use the first machine to get the debs? Does it involve setting up my own local mirror? Or a proxy server? Or can it be made simpler?

  • HP mini 5102 Ethernet does not work after suspend on Lubuntu 12.10

    - by Marcin
    Ethernet works fine after system is rebooted The onboard card is seen in 'lspci' as: 43:00.0 Ethernet controller: Marvell Technology Group Ltd. Yukon Optima 88E8059 [PCIe Gigabit Ethernet Controller with AVB] (rev 11) After system being suspended the sky2 driver loads but does not enable the NIC. I have noticed that it happens when PC is left suspended for longer period of time (few houres) Trying to reproduce it I have tried to load the sky2 driver with 'modprobe sky2'. Unfortunately typing 'ifconfig -a' for the onboard ethernet adapter does not list the driver once the sky2 driver is loaded. I have searched internet and I found some information about a bug in kernel. Hovewer it was reported in 2010 so I hope it has been fixed. Here it is http://lists.opensuse.org/opensuse-bugs/2010-02/msg01473.html

  • Ubuntu ver 14.04 Network discovery not showing up on windows 8 but on windows 7

    - by Schwabber
    I have an old PC that is now my new Ubuntu machine. Currently I was working on sharing a drive so that backups and streaming could take place. I have it set up perfectly on my windows 7 laptop (able to read and write to it). For some reason however my wife's windows 8 laptop is not showing up on the Ubuntu and vice versa. I turned on network discovery on the win8 machine, but that didn't help. Thanks in advance edit- I have my win7 and win8 in the same homegroup and both can see each other in the network. Also the workgroup is the same.

  • Strategy to prevent players from seeing through walls in an online FPS?

    - by geneotech
    Why do we still moan on wallhackers in multiplayer first-person shooters ? Isn't it possible to perform occlusion culling for all players server-side ? For example, send player xyz information to client only when the player is visible in client's frustum and not occluded by any object ? Even if the collision-geometry is very simplified, most of the time cheater won't receive tactical information. Why not do this ?

  • Why dhclient is still running when I choose static IP?

    - by user276851
    I modify dhcp to static in /etc/network/interfaces (like below). # The primary network interface auto eth0 iface eth0 inet static netmask 255.255.0.0 address 10.10.130.128 gateway 10.10.1.1 Then restart the interface. $ sudo ifdown eth0; sudo ifup eth0 ... $ ifconfig eth0 Link encap:Ethernet inet addr:10.10.130.128 Bcast:10.10.255.255 Mask:255.255.0.0 So the new address kicks in. But DHCP is still there? $ ps aux | grep dhc root ... dhclient3 -e IF_METRIC=100 -pf /var/run/dhclient.eth0.pid -lf /var/lib/dhcp/dhclient.eth0.leases -1 eth0 Is that normal? If not, how to restart interface in static IP while stop DHCP at the same time? Thanks a lot.

  • SnapBird Supercharges Your Twitter Searches

    - by ETC
    Twitter’s default search tool is a bit anemic. If you want to supercharge your Twitter search, fire up web-based search tool SnapBird and dig into your past tweets as well as those of friends and followers. Yesterday I was trying to find a tweet I’d sent some time last year regarding my search for an application that could count keystrokes for inclusion in my review of the app I finally found to fulfill the need, KeyCounter. Searching for it with Twitter’s search tool yielded nothing. One simple search at SnapBird and I nailed it. SnapBird requires no authentication to search public tweets (both your own and those of your friends and follows) but does require authentication in order to search through your sent and received direct messages.

  • Seeking advice on tools and technology for my new game [closed]

    - by k.k. slider
    I'm a C# developer who has been programming a game in my spare time using XNA and Visual Studio. The game's logic is mostly done and I've completed a prototype that has most of the functionality of (what I envision to be) the final game. However, having heard about the uncertain future and (possibly) limited audience for XNA games, I'm looking to switch platforms... but I don't know what technology would best suit my needs. Below are some specifics about my game and what exactly I'm looking for, if you're interested: The game is a 2D turn-based tactical RPG (strategy game) for two players. It is a basic sprite and tile based game with animations and sound. 3D capabilities are not necessary. I'd like to allow players to compete with others online, and have a basic ranking/matchmaking system. I will probably need something that can interact with a server and a database (the game is turn-based and has no RNG, so cheating would be easy to detect even if most computation is done client-side and minimal data is sent to the server). Ideally, I would be able to release an early version of the game and have people give feedback as I develop additional features (similar to Minecraft). I'd prefer to have a way to release periodic updates to the game instead of releasing an absolute final product. To reach the widest possible audience, I'd prefer technology that allows me to release on PC, Android, iOS, and (maybe) Mac. This is a game with simple mouse inputs which can fit on a mobile touch screen. The game should be monetizable. If I find success with this game, then I may consider becoming a full-time indie game developer. I have several other game ideas and have learned quite a bit from my first attempt at game development. My first thought was an F2P/microtransaction model, but I'm open to other suggestions. Language isn't a primary concern of mine, since I have a decent amount of experience using several languages to program large projects. I'm willing to spend money (e.g. on a developer's license), but the more expensive it gets, the more hesitant I am to use it. I've looked into the following solutions... there are a LOT of tools out there... if anyone has experience with any of these and would like to recommend/reject any of them, it would be helpful. C#/.NET (XNA/MonoGame/SDL/SlimDX/Xamarin/ExEn/ANX?) HTML5/JS (AppMobi/PhoneGap/Marmalade/FlashCanvas/Cordova/libRocket?) Python (Pyglet/Pygame/Kivy?) Java (JavaFX/libGDX?) Unity/Construct 2/Cocos2D/NME/Corona/other game creation software? I'd like something that can do 2D and isn't limited by being too high-level. Other languages (Lua/LOVE? Moai?) Thanks for answering this rather long and tedious question...

  • How to perform game object smoothing in multiplayer games

    - by spaceOwl
    We're developing an infrastructure to support multiplayer games for our game engine. In simple terms, each client (player) engine sends some pieces of data regarding the relevant game objects at a given time interval. On the receiving end, we step the incoming data to current time (to compensate for latency), followed by a smoothing step (which is the subject of this question). I was wondering how smoothing should be performed ? Currently the algorithm is similar to this: Receive incoming state for an object (position, velocity, acceleration, rotation, custom data like visual properties, etc). Calculate a diff between local object position and the position we have after previous prediction steps. If diff doesn't exceed some threshold value, start a smoothing step: Mark the object's CURRENT POSITION and the TARGET POSITION. Linear interpolate between these values for 0.3 seconds. I wonder if this scheme is any good, or if there is any other common implementation or algorithm that should be used? (For example - should i only smooth out the position? or other values, such as speed, etc) any help will be appreciated.

Im planning on having different access for certain computers so computer 1 has full access but say computer 2 can only see a certain folder. My question is, is this possible and how would i go about setting it up? All workstations are using Windows XP - Vista.

  • wired connection not being recognised in ubuntu 10.04 lts

    - by arun
    I have windows7 installed on my C drive and ubuntu 10.04 lts on my D drive. When I plud the lan cable (ethernet cable) onto the ethernet card of my laptop, windows7 identifies the network correctly without the need for any manual settings and connects me to the network correctly. Unfortunately, in ubuntu, even after plugging in the cable, nothing happens (on the network side). It is only scanning for wireless networks it seems, and doesnt bother about the wired networks. I tried adding a new wired connection and manually entered the physical address which was displayed when i connected to the network using windows. i entered the phy address, and told it to use auto dhcp and saved the dialog bog in ubuntu network connection. Still there is no change, and ubuntu doesnt seem to recognise anything. please let me know how to work with wired connections using ubuntu, and why my wired cable is not being recognized in ubuntu. thanks. PS: I am pretty new to ubuntu/ linux :)

  • Is there a simple isometric graphical game engine (using vectors?) that could be used for a (multiplayer) crafting/farming game? [closed]

    Possible Duplicate: Good, free isometric game engine? With little game development experience (albeit having graphical skills and some programming knowledge) a group currently working on a game used to explain permaculture through interaction would like to create a simple concept game. Is there a specific engine or set of tools we could used to achieve this? Being able to make it an (online) multiplayer game would be much preferred. Thank you in advance for your input.

  • Creating a 2D Line Branch (Part 2)

    - by Danran
    Yesterday i asked this question on how to create a 2D line branch; Creating a 2D Line Branch And thanks to the answered provided, i now have this nice looking main branch; *coloured to show the different segments in the final item. Now is the time now to branch things off as discussed in the article; http://drilian.com/2009/02/25/lightning-bolts/ Again however i am confused as to the meaning of the following pseudo code; splitEnd = Rotate(direction, randomSmallAngle)*lengthScale + midPoint; I'm unsure how to actually rotate this correctly. In all honesty i'm abit unsure what to-do completely at this part, "splitEnd" will be a Vector3, so whatever happens in the rotate function must then return some form of directional rotation which is then * by a scale to create length and then added to the midPoint. I'm not sure. If someone could explain what i'm meant to be doing in this part that would be really grateful.
