• How to install hardware drivers for my laptop

  - by John Flisk

  Everytime I change the OS I usually format my laptop. It is an HP tx-2 Touchsmart. It has a touchscreen and additional hardware that isn't working (i.e. volume control buttons and the network discovery) If I was on windows I would just download the hardware drivers from the HP website. How do I go about installing the software for the built-in hardware of my laptop? I am new to the community and I really want to get this computer working like it used to, to get the full Ubuntu experience. Please direct me, thank you.

• Any good web frameworks for asynchronous multiplayer games?

  - by Steven Stadnicki

  I'm trying to craft a site for web-based (original) board games, and my client (currently written in Actionscript, but that's highly fungible) works fine - I can play solitaire games in the client - but it has nothing to connect to. What I'm looking for is a server framework for handling accounts/authentication and game tracking: something that would let players log in, show them a list of their current games, let them invite friends to new games, let them make moves in the games they have open, etc. I'm flexible on language; obviously I'm going to have to write a lot of server code to handle the actual game logic, but that should be straightforward enough. I'm more concerned with how to handle the user (and game) DBs, though suggestions for a good server framework for communicating with the DBs (and serving up, most likely, JSON for client communications) are also welcome. Right now my leaning is towards Ruby (probably with Rails) but as far as I can determine it would be a pretty good chunk of effort to set up the necessary databases, so having something even higher-level would be really useful to me.

• How can I prioritize wireless networks with network-manager

  - by kynan

  Mostly I use my laptop in an environment where different wireless networks are available and I would like to preferably connect to one of those and only fall back to the other one if that one is not available. Is there any way of prioritizing which wireless networks network-manager preferably connects to? The only workaround I found so far was unchecking Connect Automatically in the options and re-enabling it when my preferred network is not available.

• How do I get to work my Atheros AR9485 Wireless card in Ubuntu 14.04 LTS?

  - by Ivan Kreimer

  I've recently installed Ubuntu 14.04 LTS in my ASUS D550CA, and so far things have gone great. The only problem I've got is the Wi-Fi. It doesn't work. I've got an Qualcomm Atheros AR9485. I've tried installing the drivers, but the sytem says it doesn't find any. So I started looking around this forum for solutions. I've read every single post from this forum about my Wi-Fi network adapter, and I've found nothing that solves my problem. Let me give you some info about my configuration. Disclaimer: my configuration is in spanish, so if you don't understand something you can either use Google translate, or use your imagination. :D When I run $ sudo lshw -C network this is what I get: *-network DEACTIVATED descripción: Interfaz inalámbrica producto: AR9485 Wireless Network Adapter fabricante: Qualcomm Atheros id físico: 0 información del bus: pci@0000:02:00.0 nombre lógico: wlan0 versión: 01 serie: 28:e3:47:5c:5d:3f anchura: 64 bits reloj: 33MHz capacidades: pm msi pciexpress bus_master cap_list rom ethernet physical wireless configuración: broadcast=yes driver=ath9k driverversion=3.13.0-34-generic firmware=N/A latency=0 link=no multicast=yes wireless=IEEE 802.11bgn recursos: irq:17 memoria:f7d00000-f7d7ffff memoria:f7d80000-f7d8ffff *-network descripción: Ethernet interface producto: RTL8101E/RTL8102E PCI Express Fast Ethernet controller fabricante: Realtek Semiconductor Co., Ltd. id físico: 0.2 información del bus: pci@0000:03:00.2 nombre lógico: eth0 versión: 06 serie: e0:3f:49:ce:57:49 tamaño: 100Mbit/s capacidad: 100Mbit/s anchura: 64 bits reloj: 33MHz capacidades: pm msi pciexpress msix vpd bus_master cap_list ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd autonegotiation configuración: autonegotiation=on broadcast=yes driver=r8169 driverversion=2.3LK-NAPI duplex=full firmware=rtl8402-1_0.0.1 10/26/11 ip=181.165.245.39 latency=0 link=yes multicast=yes port=MII speed=100Mbit/s recursos: irq:41 ioport:e000(size=256) memoria:f0004000-f0004fff memoria:f0000000-f0003fff At the beginning, you'll see that it says "*-network DEACTIVATED" (or at least that's what I translated), is that something bad?

• Better way to set up samba bridge?

  - by Adam Butler

  I have an old ubuntu laptop hooked up to between my wireless network and a wired media player box. I had previously shared my wireless network connection so the media player had internet access (ie. via nat) because it was a different subnet it could not access the file shares on the wireless network. To get around this I mounted the drives from the wireless network on the laptop and re-shared them with samba. This worked ok but had some drawbacks, it seemed slow and if network computers were turned off when the laptop rebooted I had to manually mount the shares. I've just re-installed with the latest ubuntu and was wondering if there is a better way to do this. Is there some way to bridge so the media player appears to be on the wireless network? Would this give better performance? Any other options? I'm also thinking there might be some samba options that could buffer files?

• Turn-based Client-Server Card Game - Unicast (TCP) or Multicast (UDP)

  - by LDM91

  I am currently planning to make a card game project where the clients will communicate with the server in a turn-based and synchronous manner using messages sent over sockets. The problem I have is how to handle the following scenario: (Client takes it turn and sends its action to server) Client sends a message telling the server its move for the turn (e.g. plays the card 5 from its hand which needs to placed onto the table) Server receives messages and updates game state (server will hold all game state). Server iterates through a list of connected clients and sends a message to tell of them change in state Clients all refresh to display the state This is all based on using TCP, and looking at it now it seems a bit like the Observer pattern. The reason this seems to be an issue to me is this message doesn't seem to be point-to-point like the others as I want to send it to all the clients, and doesn't seem very efficient sending the same message in that way. I was thinking about using multicasting with UDP as then I could send the message to all the clients, however wouldn't this mean that the clients would in theory be able to message each other? There is of course the synchronous aspect as well, though this could be put on top of the UDP I guess. Basically, I would like to know what would be good practice as this project is really all about learning, and even though it won't be big enough to encounter performance issues from this I would like to consider them anyway. However, please note I am not interested in using message oriented middleware as a solution (I have experience with using MOM and I'm interested in considering other options excluding MOM if TCP sockets is a bad idea!).

• How to restart WiFi interface without rebooting (it drops connection)?

  - by Dima

  I boot into ubuntu and it connects to the Wifi network fine. After about 10-15min the DNS stop resolving any website and a couple of minutes later network-managers tells me that I'm disconnected and tries to reconnect constantly to my router and fails to do it. Upon Ubuntu restart everything works fine for the first 10-15min again. When I boot into Mac OS X everything is fine with the same connection! How do I restart wifi interface? sudo ifdow wlan0 just tells me that wlan0 is not configured and wlan0 doesn't appear in /etc/network/interfaces either, which I find strange.... (unless network-manager is doing it behind my back).

• Use same dns server for all (future) connections

  - by kleofas

  I'm wondering if it is possible to specify, that all connections (even future, like when using wifi at some other place (=different SSID)) will be using pre-defined DNS server When I have some (concrete) connections, I could go to IPv4 settings, and specify DNS server there (however, in case of new connection I would have to do it (and not forget it)) This may be particularly useful for some safe/filtering dns (such as opendns's 208.67.222.123 & 208.67.220.123)

• There's IP but can't reach gateway

  - by icky

  I have just installed ubuntu 12.04 on my new laptop, and brought it back to home, but I found the wireless network does not work. Strangely, it has the correct ip, but can't connect to the gateway. ifconfig gives ip 192.168.64.36, with broadcast 192.168.79.255 and mask 255.255.240.0, this are all correct, the gateway is at 192.168.64.1 cat /etc/resolv.conf nameserver 192.168.64.1 nameserver 127.0.0.1 which i think it's also right. but when I ping 192.168.64.1, all packages are lost. Please help me with this, I really do not know what happened to my network settings. Huckle, Thank you for your reply ifconfig wlan0 Link encap:Ethernet Hwaddr 88:f9:af:2a:ca:1b inet addr:192.168.64.36 Bcast:192.168.79.255 Mask:255.255.240.0 inet6 addr: fe80::8a9f:faff:fea2/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:27 errors:0 dropped:0 overruns:0 frame:0 TX packets:376 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:3950 TX byetes:60288 iwconfig wlan0 IEEE 802.11bgn ESSID:"Chiono" Mode:Managed Frequency:2.417 GHz Access Point: 82:54:99:94:6D:43 Bit Rate=13.5 Mb/s Tx-Power=13 dBm Retry long limit:7 RTS thr:off Fragment thr:off Encryption key:off Power Management:on Link Quality=70/70 Signal Level=-32 dBm Rx invalid nwid:0 Rx invalid crypt:0 RX invalid frag:0 Tx excessive retries: 9 Invalid misc:10 Missed beacon:0 route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface default 192.168.64.1 0.0.0.0 UG 0 0 0 wlan0 link-local * 255.255.0.0 U 1000 0 0 wlan0 192.168.64.0 * 255.255.240.0 U 2 0 0 0 wlan0 Thank you very much

• 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?

• Best way to handle realtime melee AI in authoritative network environment

  - by PrimeDerektive

  So i've been working on a multiplayer game for a bit; it's a co-op action RPG with real-time combat. If you've seen or played TERA, I'd say it's comparable to that, but not an MMO, heh. I'm currently handling the AI units authoritatively, the server calculates their pathing, movement, and pursue/attack logic, and syncs the movement to the clients 15x per second, and the state changes when they happen. When I emulate 200ms ping, though, the client can perceive being out of range to an AI's attack, but still take the hit, because on the server he hadn't moved that far yet. This also plays hell with my real-time blocking. I don't really want to allow the clients to be allowed to say "that was out of range" or "I blocked that", but I'm not really sure how else to handle it.

• Connecting to VPN / proxy with different port number

  - by user779159

  I have an IP address, port, username, and password for one of those VPN / proxy services that allows you to use an IP address other than what your ISP gives you, but in the 'Edit Connections VPN' GUI I don't see where to enter a port. I enter the IP address under 'Gateway' and the username and password where it asks for it, but it doesn't work. I try to enter it with the IP address ending with a colon, followed by the port, but that doesn't work either (e.g. "1.1.1.1:9999"). Any idea how I could make it work? I'm using Ubuntu 12.04 LTS. Thanks.

• Modular Web App Network Architecture

  - by nairware

  Assuming that I am dealing with dedicated physical servers or VPSs, is it conceivable and does it make sense to have distinct servers setup with the following roles to host a web application? Reverse Proxy Web server Application server Database server Specific points of interest: I am confused how to even separate the web and application servers. My understanding was that such 3-tier architectures were feasible. It is unclear to me if the app server would reside directly between the web and database server, or if the web server could directly interact with the database as well. The app server could either do the computational heavy-lifting on behalf of the app server or it could do heavy-lifting plus control all of the business logic (as implied in the diagram above, thus denying the web server of direct database access). I am also unsure what role the reverse proxy (ex. nginx) could and should fulfill as a web server, given the above mentioned setup. I know that nginx has web server features. But I do not know if it makes sense to have the reverse proxy be its own VPS, given that the web server–in theory–would be separate from the app server.

• Help setting up wireless in Ubuntu 13.04

  - by James

  I'm having problems connecting my WIFI in Ubuntu 13.04 . So I was wondering if filling in the data manually ie: the IPv4, IPv6, the SSID and BSSID info etc. I did try this before but maybe I put in the wrong data or maybe not enough. Would that make it work? I just don't know how to find out some of the data you need to put in? I'm new and it's confusing. Does anyone know the solution?

• 12.04 - why does the network icon dissapear every time my machine is turned off

  - by Howard Walker

  After spending an hour or two working out how to find the network Icon, I find that when I reboot the machine, I have to go through the whole procedure again. 1. The network menu is not there - so first I have to find the terminal. This has no particular location that I can find but usually I have to type terminal in the dash. 2. Then I have to type nm-applet in terminal 3. The network manager icon then appears, but only works if the terminal window remains open. Shut down the terminal window and the network disappears. This is a pain - plus I have to type my password in every time, which is another waste of time, thought this has always been a problem. So can anyone tell me how to make the web automatically connect at startup without any intervention from me.

• Network sharing for android

Now I know there are so many tutorials available every where and that I have all options in network tab to use but I couldn't get it to work. Android does not work with an adhoc connection and whatever wifi network I created, my android device could not connect to it (I could connect a phone using bada to it and other computers can also be connected) I know the work around to get android on a adhoc connection but can't I have some thing as simple as connectify for windows? PS : I am not looking for workarounds involving android.

• Ubuntu 12.04 host – Virtualbox 4.1.12 Guest=Windows 7 – Network will not connect

  - by user287529

  Ubuntu 12.04 host – Virtualbox 4.1.12 Guest=Windows 7 – Network will not connect. I'm using Ubuntu 12.04 on an Acer Aspire 5742-7645 laptop with 4GB memory, Intel Core i3 processor, Intel HD Graphics, DVD drive, 802.1 b/g/n, and 500 GB HD. I connect to my router via a wireless connection. I have installed Virutalbox 4.1.12 from the Ubuntu Software Center and installed Guest additions 4.1.12 in the Windows 7 guest session. I have Windows XP and Windows 7 installed as guests in Virtual box The network settings are different for XP and 7 – see below. Network Settings XP guest = Adapter 1: PCnet-FAST III (NAT) - Network works perfectly and has worked well for several years. Network Settings Win 7 = Adapter 1: Intel PRO/1000 MT Desktop (Bridged adapter, eth1) Promiscuous Mode = allow all Cable connected = checked When I originally installed Windows 7, I tried NAT and the guest network would not connect. Once I changed the setting to the above (Bridged) the Network worked perfectly. However, what I believe is after updates (not sure if it was an Ubuntu or Windows update) the guest network stopped working and I can not get it to connect.

  I'm interested in how bots are usually written. Here's my situation: I plan to make an online 2D mecha game in HTML5, and the server-side will be done with node. It is intended to be multiplayer, but I also want to make bots in case there aren't enough players. How does my game logic see them, as players or as bots? Is there a standard by which I should make them? Also, any general tips and hints will be OK.

• Bridge Laptop's Ethernet to Wireless

  - by Kalphiter

  The laptop wirelessly connects to my router, while the desktop is connected to the laptop with an ethernet wire. The desktop successfully can use the internet if I set the connection to be shared on the laptop. The problem is, I need the laptop to forward the desktop's packets across the link unmodified, so the desktop is on the same network as the router. The desktop needs its IP assigned by the router, so that I can access it from another computer as "192.168.1.8".

• A "tinkered" PC can ping by IP, not by hostname. How to fix?

  - by aitchnyu

  Like this: root@tis-server:~# ping www.google.com ping: unknown host www.google.com root@tis-server:~# ping 8.8.8.8 PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data. 64 bytes from 8.8.8.8: icmp_req=1 ttl=55 time=50.3 ms 64 bytes from 8.8.8.8: icmp_req=2 ttl=55 time=65.4 ms It was tinkered by somebody else and I (and him!) cant trace his actions. The graphical connection manager also refuses to work thanks to the tinkering. It also makes route add default gw 192.168.0.1 necessary for each reboot to atleast ping by IP. How do I fix this?

• How to get Wifi Working Properly - I am Noob

  - by user287853

  I'm a noob to Ubuntu, but not computers. I installed a full version of Ubuntu version 12 whatever it is. I run it on a machine that has Win7/Win8 on another hard drive. My wireless adapter is some tiny USB stick I got on eBay - it works great in Windows, but I can't get it to work in Ubuntu. More precisely, Ubuntu is providing me a list (sometimes) of wireless networks in the area and when I try to connect to mine it just keeps password prompting me even though the one I use is correct. I looked over all the settings multiple times and don't believe there is anything in error regarding what it takes to connect to my network. So, I thought maybe it is a driver issue and came across NDIS. I thought I should try installing it, but I don't know how when I can't connect the Ubuntu machine to the Internet. I tried some commands to no avail. I have the Ubuntu installation disc and it shows a NDIS common and utils .deb files in there. Can someone out there help me out to get this wireless setup so I can get online?
