• Connect to new wireless network

  - by Shawn de Wet

  Wireless networking was working perfectly on my old adsl router. Then I moved to a new home that does not have adsl, and the router has been replaced with a new 3G one. I have worked through the following links: Connecting to a wireless network and http://ubuntuforums.org/showthread.php?t=571188 I have set the router from it's default WPA-PSK encryption to WEP encryption and also to No Encryption. But when I get to dhclient -wlan0, I keep getting No DHCPOFFERS received. Yet the 2 windows machines in my home connect fine to this wirelesss network (in all encryption settings). If I try iwlist scan I can see that the wireless network is indeed visible. Where do I start scratching to see where the problem may lie.

• Can't connect VPN/add new VPN connection on 12.04 when using NX

  - by dbotamous

  I remote control my Ubuntu box using NX. I am trying to create a new VPN connection. I click on Configure VPN ? Add ? OpenVPN ? Create then I get a "Editing VPN connection 1" window but everything is grayed out, and I can't edit it. The only button I can click is Cancel. The reason I bring up NX is because if I plug in a monitor keyboard and mouse, I can create, edit import VPN connections just fine. So I imported all the different VPN connections, everything was fine. I then remoted back into the Ubuntu machine with NX, click on my VPN connection, and get VPN Connection Failed - The VPN CONNECTION failed to start. Not authorized to control networking. I then disconnected and reconnected NX, and now all the VPN connections I had imported are gone. Any ideas?

• Slow Wireless Reconnect After Suspend - Broadcom 4312 with STA drivers

  - by nrhine1

  I am using 10.10 with STA drivers, I reinstalled ubuntu because the b43 drivers were giving me a huge hassle along with some weird kernel issues. My wireless speed is fine, everything works well, except upon restart of computer and after taking the computer out of suspend. It takes about 30-45 seconds for the wireless to reconnect, and I think it is a driver issue (I clicked on the network manager at the top and for about 30 seconds there are no wireless networks listed.) I tried this advice already: http://lilserenity.wordpress.com/2007/10/31/fix-ubuntu-dropping-wireless-on-suspendhibernate-resume/ which basically says to change this: STOP_SERVICES="" to STOP_SERVICES="networking" in the file /etc/default/acpi-support This did not help anything. Something to note is that the issue does not occur when I am logging back in after already logging in once and logging out.

• Game Programming Resources for Programmers

  - by user17028

  I am a self-taught high school programmer (have an internship at local university), and understand the fundamentals of C++ and other related languages. I am looking to expand into game development, and have found a good DirectX book from which I will study. However, what are some good resources (online tutorials/books/etc) for C++ game programming which are tailored towards someone who is already experienced with C++? Most of the resources I have found attempt to teach basic programming, then get into game development.

• Ubuntu and VirtualBox

  - by Sinan

  I have the following configuration, A host running Windows 7; A guest running Ubuntu 14.04 LTS (VirtualBox); I am connecting a Cisco router directly to my PC running Windows 7 and testing the router for netflow packets in the virtualBox I am having a difficulty capturing the traffic of the netflow from the Cisco device in my virtualBox using port 2222. I tried to use the many different networking modes provided by virutalBox (i.e. NAT, Bridged Adapter, Host only adapter) but I am not successful in capturing the netflow traffic. Could you please advise me on the configuration setup that need to be done on the virtual box to allow capturing the traffic coming from the router. I successfully capture the netflow traffic on my PC (windows 7). Thank you

• How was programming done 20 years ago?

  - by Click Upvote

  Nowadays we have a lot of programming aids that make it easier to work, including: IDEs Debuggers (line by line, breakpoints, etc) Ant scripts, etc for compiling Sites like Stackoverflow to help if you're too stuck on a bug. 20 years ago none of these things were around, which tools did people use to program and how did they make do without these tools? I'm interested in learning more about how programming was done back then.

• Can not resolve hostnames on Xubuntu computers

  - by P Curtis

  I have a network of computers which has been running for many years. I have changed two of those to Xubuntu 11.10 and found I can no longer connect by ssh using the host-name from any other machine. I can connect and ping by IP although ping is very slow in one case (~200ms). All other machines are fine including another with Ubuntu 11.10. Host-name resolution works from Xubuntu machines to other networked machines. I am using wins resolution and have checked settings in /etc/nsswitch.conf are the same as my working Ubuntu systems. What is different in Xubuntu networking that I might have missed?

• How to forward an Internet connection to another network?

  - by Naveen

  Can somebody please make a shot & sweet tutorial telling how to forward an Internet connection to different network interfaces in Ubuntu...? This is the idea: I'm using a 3G usb modem to get Internet on my laptop ,which is: ppp0 IP=10.225.174.70 My Wifi device is: wlan0 MAC=78:e4:00:d4:3d:85 These devices are determined from ifconfig command. I want to share ppp0's internet connection with wlan0 device, so I can connect any other device to wlan0 and browse internet from that device. Making a Hotspot using Network settings GUI doesn't do the trick because the other device won't receive Internet, it just connects to wlan0. I heard iptables can do this, but I'm totally confused by the alien commands seen online. I'm no expert in networking. Please compose a clear & simple answer using the above devices. This is a huge annoying problem for iPhone & tablet users came to Ubuntu from Windows.

• Hybrid wireless network repeating

  - by Oli

  Summary: I'd like to use two Ubuntu computers to extend/compliment an existing wireless access point. I have a network which currently looks a bit like this: What the diagram doesn't show is the interference caused by our house. It's a wifi-blocking robot sent here from the past. The two wired computers are in areas where the signal is most blocked (not by design, just a happy co-incidence). Both wired computers have fairly good network cards. They're both Ubuntu machines and I would like to turn them into additional base stations. I know I could throw more networking hardware at this (network extenders or cable in additional, pure wireless access points) but I've got two Linux machines sitting in ideal places and I feel like they should be able to help me out. I've tried ad-hoc networks but I need something that is a lot more transparent (eg you can migrate from base to base without a connection dropping); it should look like one network to clients.

• Connecting to an Amazon AWS database [closed]

  - by Adel

  so I'm a bit overwhelmed/bewildered by the whole concept of networking/remote-desktop , etc. The context is that - in my company I need to access a remote database. The standard way I use is to first connect using a VPN-Client( called Shrew Soft Access manager), then once that says: "network device configured tunnel enabled" I'm good to connect using windows "Remote Desktop Connection" . But now our company set up an Amazon AWS database, and I'm told I need to connect, and I ony need to use RDP. So I tried the standard windows one - but it doesn't work. On wikipedia , I looked up remote desktop sftware and downloaded one called VNC Viewer. but it doesn't work. Any advice/tips/comments appreciated EDIT: YAYA! I finally got a little more connected . I had to use my username as a fully qualified name: Computer: XYZ.XYZ.XYZ.XYZ USERNAME: XYZ.XYZ.XYZ.XYZ\aazzam

• Recent programming language for AI?

  - by Eduard Florinescu

  For a few decades the programming language of choice for AI was either Prolog or LISP, and a few more others that are not so well known. Most of them were designed before the 70's. Changes happens a lot on many other domains specific languages, but in the AI domain it hadn't surfaced so much as in the web specific languages or scripting etc. Are there recent programming languages that were intended to change the game in the AI and learn from the insufficiencies of former languages?

• Changed isp, Ubuntu 13.04 won't connect to the internet

  - by Lori

  I recently moved and changed internet service providers. my ubuntu 13.04 machine is unable to connect to the internet. I need help with the networking settings. The previous isp was Verizon dsl, current a cable company. Both connect via ethernet cable. The cable and router work on a windows machine, but not my ubuntu machine. The cable company doesn't support ubuntu or any linux operating systems. The computer seems to recognize the connection. When I unplug and plug in the cable I get a little window that says disconnected, connected. However, I can't connect to the internet in either Firefox or the Ubuntu software installer (tried this to see if it was a firefox issue, it wasn't). I tried shutting down and restarting, plugging and unplugging cables, etc.

I've searched but all I get is people who can't figure out shared folders between host/guest (which I've got working)

• how to find available wireless networks

  - by Quinn

  I'm using an HP Pavilion dv6000 I've looked at other answers similar to this question how ever when I look at my network symbol it doesn't say anything that the answer below says "Make sure that your wifi hardware switch is on or not. It is either F2 or F12 or near to it. Once the switch is enabled, there is a small fan-like applet on the top panel (Gnome Network Manager), fourth from the right. Click on it and if there is no tick mark on the option 'Enable Wireless', enable it. Wait till your wifi connection name appears." it how says 'Enable Networking' my wi-fi switch is on and I've tried using terminal to kill the applet as another answer suggests trying. Does anyone have any other ideas that might help? Just in case anybodies curious as to how I'm posting this I'm on my other ubuntu laptop that's running an older version.

• Cisco AnyConnect VPN Client broke my internet

  - by user137864

  I was using the AnyConnect client when it froze and I had to do a hard reboot of my computer. Now I can't connect to the internet at all, with or without VPN. The Network Connections manager seems to think I have a wired and wireless connection without a problem, but I can't go online. I have tried using /etc/init.d/networking restart and it even says it is "ok" with no luck. I am guessing I need to clear some settings somewhere and restart a service, but I am not sure what. Thanks!
