• Programming bots in games

  - by Bane

  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.

• 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.

• 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

• Network sharing for android

  - by Shagun

  I am on ubuntu 12.04 and I want to create a wifi hotspot to be used with my android device. 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.

• Use hotplug and turn on/off PCI device for replacing NIC

  - by Ryota Hashimoto

  How can I turn off the PCI slots and change the device (especially NIC) without shutting the server down?

• Unable to use TL-WN821N

  - by udiw

  Hi, I got a TP-LINK USB wireless module - TL-WN821N, using Ubuntu 10.4 (same problems were also seen in 10.10). From everything I've read online, the usb should work just fine, since the Atheros ar9170 is built into the kernel. However, when I plug it in, it is detected as a USB device, but there is no wlan associated with it, and basically - nothing happens. Am I doing something wrong? what should I do so that the Atheros driver is associated with this device? btw, on Windows it works fine (with the drivers). Some logs: $ uname -mr 2.6.32-28-generic i686 $ lsb_release -d Description: Ubuntu 10.04.2 LTS $ lsusb ...

• 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?

• 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.

• How do I airport-utils to configure my Airport Extreme?

  - by chands

  I'm trying to use this package (airport-utils) to try to configure my Airport Extreme. I was able to install it without a problem using apt-get but when I try to use it nothing happens. Literally, nothing: shreyas@shreyas-laptop:~$ airport2-portinspector shreyas@shreyas-laptop:~$ No windows open, nothing. I tried calling ps aux and grepping for anything that might hint to the command actually doing something but I came up empty. Does anyone have any experience with this package and can help me, or is there something else I can do to work with my Airport Extreme?

• 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?

• 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?

• 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.

• 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?

• 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.

• 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.

• Wired connection problem through router

  - by tommypincha

  I'm having trouble to connect my Ubuntu 11.10 to internet through ethernet. I installed a router to get Wi-Fi and now (by a wired connection) I can't have internet with ubuntu (but I can with Windows 7). I see several attempts per minute of the network-manager to get a connection, but after a minute it stops trying. Here are a couple of outputs from key files: cat /etc/network/interfaces auto lo iface lo inet loopback and ifconfig -a eth0 Link encap:Ethernet HWaddr 00:16:76:e4:a6:e8 inet6 addr: fe80::216:76ff:fee4:a6e8/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:117 dropped:0 overruns:0 frame:117 TX packets:50 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:12221 (12.2 KB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:582 errors:0 dropped:0 overruns:0 frame:0 TX packets:582 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:46024 (46.0 KB) TX bytes:46024 (46.0 KB) I tried reconnecting the modem and the router and reconnecting the ethernet cable but nothing... I tried other solutions from other posts (this one has a similar issue Wired connection not working) but again nothing. My IP is dynamic. A couple of things I see and did: I see no inet addr, only inet6. I ignored ipv6 from the internet connections, and restarted the network-manager service and nothing. A difference with the post I mentioned is the RX packets with errors I have, is this a clue of the problem? Any help would be appreciated, Thanks!

• How to rewrite a TCP MMOG server designed to run in a single machine, in a distributed way?

  - by Dokkat

  I have a MMOG server running on C++, using winsockets. My server won't support more than 200 players. I had the idea of redesigning it so it will use multiple servers instead of one, so, maybe, for example, each server could take care of a number of players, and, if it was too laggy, it could transfer the responsability of that player to other server. I'm not sure of how to program a consistent game logic like that, though. Are there techniques for this?

• 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".

• 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.

What seems to be the problem and how can I fix it? Thank you.

• gnome-file-share-properties doesn't work

  - by Riccardo Magrini

  I've configured gnome-file-share-properties on all my Ubuntu's PC for sharing the directory Public to each other. I following some guide found on Internet for the configuration of it, all explain the same procedure but in my case I don't see any Public directory shared with the PC. Following this link http://library.gnome.org/users/gnome-user-share/stable/gnome-user-share-getting-started.html.en I'd see the directory Public plus the name of PC that shares its directory on Nautilus Places. In my case I don't see anything, therefore on the Network place see all the machines 'n if I try to click on one receive this: "DBus error org.freedesktop.DBus.Error.NoReply: Message did not receive a reply (timeout by message bus)" note: I don't want to use Samba because I've all Ubuntu PC, and the firewall is disabled on all PC.

• Sharing an internet connection through the Ethernet port

  - by Bob Cunningham

  I have a small living room PC (Bohica, running fully-updated Ubuntu 10.10/Maverick) connected to my HDTV that I use for web browsing and media streaming. It connects via WiFi (wlan0) to my Fedora server (Snafu) that in turn connects to the internet. I use static addressing, and everything has been working fine. I just got a Blu-ray player, and I'd like to give it wired network access to the internet via Bohica's available wired ethernet port (eth0). So far, I haven't been to get eth0 and the network configured to get the Blu-ray player talking to the internet. Here's my wlan0 configuration: ip4 addr: 192.168.0.100 mask: /24 (255.255.255.0) gateway: 192.168.0.4 (fedora box) The Blu-ray player is set to an IP of 192.168.0.98/24, with the same gateway as above. I want eth0 set to an IP of 192.168.0.99/24, but when I do this using nm-connection-editor I lose internet access (the system tries to use eth0 as the default internet access interface). How do I get my blu-ray player to talk to the internet through Bohica, and do so without disrupting my current (working) network? Thanks. Edit: Here's the relevant output from nm-tool with the Blu-ray player connected: $ nm-tool NetworkManager Tool State: connected - Device: eth0 Type: Wired Driver: forcedeth State: disconnected Default: no HW Address: 90:FB:A6:2C:94:32 Capabilities: Carrier Detect: yes Speed: 100 Mb/s Wired Properties Carrier: on - Device: wlan0 [wlan0] Type: 802.11 WiFi Driver: ndiswrapper State: connected Default: yes HW Address: 00:26:5A:C0:D0:05 IPv4 Settings: Address: 192.168.0.100 Prefix: 24 (255.255.255.0) Gateway: 192.168.0.4

• Is there a way to disable a particular pci port

  - by mxdog

  I have a MB with 2 nics on it. a switch burned up and took out one of them. there is no way to turn them off individually in the bios. is there a way to turn off one of the ports. unmap it,unbind it, power it down so the system doesnt see it at after boot. they are mapped as 0000:02.08.0 and 0000:02.08.1 I want to turn the second one off somehow. Since they both use the same driver, blacklisting the module will take out both of them. Normally I would just live with it but it seems there should be a way to do that like in windows (gasp)--just disable it. I Actually have the exact same problem on another comp running XCP so this will be a 2fer if it gets figured out. the OS is 12.4 lts server with xen on it. THX
