  • What is the best way to bypass China firewall to allow SSH deploy@**.com

    - by Lap
    I am trying to bypass the china firewall and allow SSH deploy@**.com at the command console. This is because I need to test the games I wrote on apps.facebook.com/**. I tried VPN (both pptp and openvpn), but they aren't that great as connection speed slows down significantly. Since I am deploying the game in another site, my browser needs to download the game, which is super slow. What are ways of bypassing the firewall other than getting a VPN? I was thinking maybe have a computer outside China and using teamviewer to access...

  • IE6 Support - When to drop it? [closed]

    - by Scott Brown
    Possible Duplicate: Should I bother supporting IE6? I'm thinking about IE6 support and when to give up on it. Do you have a percentage of total visitors figure in mind for when to drop support? Would you let a trend develop past this figure or are you just going take the first opportunity? I've seen a 44% drop in IE6 visitors in the past 12 months from 23%(ish) of visitors down to 13%(ish). Even if it was 5% it still seems too early to drop support to me (it's still 1 in every 20 users). What are people's thoughts on this?

  • router cannot get ip address

    - by user43208
    Hi guys, I have a linksys router WRT54G2 connected to a cable broadband. Just last week, everything was working perfectly - I would be able to connect my laptop to the internet using WiFi. However, starting last week, I suddenly lost my internet connection. At first I thought something was wrong with my ISP. However, when I tried connecting the cable directly to my laptop, I found out that there was no problem with the internet connection after all. It appears that it is only my router that cannot get IP address. I have already tried cloning my MAC address and reconfiguring my router using the setup CD, but nothing worked. What could be the problem here? Thank you. Regards, Erwin

  • Unknown CSS font-family oddity with IE7-10 on Windows Vista, 7, 8

    - by Jeff
    I am seeing the following "oddity" with IE7-10 on Windows Vista, 7, 8: When declaring font-family: serif; I am seeing an old bitmapped serif font that I can't identify (see screenshot below) instead of the expected font Times New Roman. I know it's an old bitmapped font because it displays aliased, without any font smoothing, with IE7-10 on Win Vista-8 (just like Courier on every version of Win). Screenshot: I would like to know (1) can anyone else confirm my research and (2) BONUS: which font is IE displaying? Notes: IE6 and IE7 on Win XP displays Times New Roman, as they should. It doesn't matter if font-family: serif; is declared in an external stylesheet or inline on the element. Quoting the CSS attribute makes no difference. Adding "Unkown Font" to the stack also makes no difference. New Screenshot: The answer from Jukka below is correct. Here is a new screenshot with Batang (not BatangChe) to illustrate. Hope this helps someone.

  • Some websites are not opening in any web browser (firefox/chrome). What should I do? [closed]

    - by Jamal
    Some websites are not opening in my system. I am using Ubuntu 12.10. Earlier, when I was using Ubuntu 10.10,11.10 there was no such issue. The problem was started in ubuntu 12.04, but it remained the same even after formatting and installing ubuntu 12.10. I have tried Firefox as well as Chromium and I am sure the issue is not with the browser. same websites are opening perfectly with Windows. Google, Twitter and Ubuntu related websites are running perfect. Other websites like www.downrightnow.com, easy-mantra.com, facebook.com, sourceforge.net are not opening.

  • Duplicity can't connect to CloudFiles "Network is unreachable"

  • # id - urls with id first display full page, then move to #id

    - by guisasso
    I've noticed this in the new version of chrome, and ie9 and 10. Some urls in a photo gallery have a #id tag as they are supposed to display a full view of a picture. Basically, a div in a lower position on the page has that #id that i call via a.com/1.html#id. This has never been an issue until lately, when i noticed a bit of a lag. The issue: The website loads normally, then the view moves to the #id as supposed, but with some lag sometimes, perhaps because of the high resolution of the picture, which is somewhat noticeable. Anyway to avoid this, or make it so the page would move to the correct #id even before fully loaded?

  • WiFi and Bluetooth will not work on Dell Studio XPS 1645

    - by Ross
    Today I acquired a Dell XPS 1645. Ubuntu seems to run alright on it however The bluetooth is not detected and the WiFi doesn't work. The WiFi is especially weird because I actually have the restricted driver enabled for it. It also worked for a short while when I first booted into Ubuntu however now there isn't even an option to enable wireless. If anyone could possibly help me out with this I'd deeply appreciate it. I've not had to return to Windows for a good while and it's not something I want to have to do now.

  • nvidia-settings makes one of my dual monitors grey and useless, disables network

    - by Kerrick
    I'm running Ubuntu 12.04 64-bit, Precise Pangolin, with a PNY GTS 250 1GB video card and a monitor plugged into each of the DVI ports. I'm using the proprietary drivers (post-release updates). If I set anything to do with Separate X Screens up in nvidia-settings (and write it to xorg.conf and reboot), my second monitor has a grey background, no menu bar, no ability to have a window on it, the second monitor doesn't get picked up in a screneshot, and if I move my mouse cursor to it it's an ugly black X. Plus, my network is unable to connect to anything. If I subsequently delete /etc/X11/xorg.conf and reboot, everything goes back to working, albeit with a single monitor activated. If I set anything to do with TwinView up in nvidia-settings, my second monitor starts working, but it isn't seen as a second monitor by Ubuntu, so I can't apply color calibration to it separately. Plus, my mouse gets "caught" between the monitors every time I try to move my cursor between the two. What gives? If it helps, this is the xorg.conf that nvidia-settings generates for Separate X Screens.

  • Ubuntu KVM Networking

    - by Guest
    I have two VMs ( linux based VM ) running on a UBUNTU/QEMU KVM. I am looking at a simple networking model, where in the VMs have public address and need to talk to the outside world and the outside world should be able to talk to the VMs as well. I did this Created a bridge with A.B.C.D/16 ( class B address ) eth2 is part of the brige with A.B.C.E /32 host address VM's interface ( through TAP ) has A.B.C.F / 16 address eth2 and VM interface are both part of the bridge. Now however, I am unable to ping these address from the outside world. If i remove eth2 from the bridge, I am able to ping the eth2. Please let me know what is going on. Guest

  • Using Google App Engine to Perform World Updates vs an Authoritative Server

    - by Error 454
    I am considering different game server architectures that use GAE. The types of games I am considering are turn-based where the world status would need to be updated about once per minute. I am looking for an answer that persuades me to either perform the world update on the google servers OR an authoritative server that syncs with the datastore. The main goal here would be to minimize GAE daily quotas. For some rough numbers, I am assuming 10,000 entities requiring updates. Each entity update would require: Reading 5 private entity variables (fetched from datastore) Fetching as many as 20 static variables (from datastore or persisted in server memory) Writing 5 entity variables Clients of the game would authenticate and set state directly against GAE as well as pull the latest world state from GAE. Running the update on GAE would consist of a cron job launched every minute. This would update all of the entities and save the results to the datastore. This would be more CPU intensive for GAE. Running the update on an authoritative server would consist of fetching entity data from the GAE datastore, calculating the new entity states and pushing the new state variables back to the datastore. This would be more bandwidth intensive for the datastore.

  • Why is Ubuntu offline (except torrents) while Windows is online?

    - by Fahim al Islam
    I am using a static wired connection. Everything was perfect. But suddenly from few hours back I can't access any website. Dropbox, Ubuntu One also can't connect. Ping request is also unsuccessful, but I can download through torrent. I am not trying torrent download and browsing at the same time. So, I think it's not an issue about torrent using all the bandwidth. One important point is that this connection works perfectly on Windows on this same PC (My PC is dual-boot). I have tried the way what izx has suggested (using "sudo sh -c 'echo nameserver 8.8.8.8 /etc/resolv.conf'"), but I'm facing the same problem again. Now I can't even ping 8.8.8.8 and google.com. Though I can ping 74.125.228.2 (which is Google IP address) I can't understand what's happening and why this is happening. I'm new in this website many rules and regulations is unknown to me. So, please don't be bothered for my mistakes. Looking forward for help from anyone. Thanks to all.

  • Tips for communication between JS browser game and node.js server?

    - by Petteri Hietavirta
    I am tinkering around with some simple Canvas based cave flyer game and I would like to make it multiplayer eventually. The plan is to use Node.js on the server side. The data sent over would consists of position of each player, direction, velocity and such. The player movements are simple force physics, so I should be able to extrapolate movements before next update from server. Any tips or best practices on the communications side? I guess web sockets are the way to go. Should I send information in every pass of the game loop or with specified intervals? Also, I don't mind if it doesn't work with older browsers.

  • Multiplayer game communication framework for mac/ios

    - by ishaq
    (Cross post from stackoverflow) I am creating a multiplayer 2D game for Mac and iOS devices. I'll be using cocso2d for graphics/game engine, however I am largely blank on what to use for multiplayer communication. Please note that I cannot use central severs e.g. SmartFox, RedDwarf, etc since I want the players to "host" games for others and be able to play it on their LAN, VPN or my own servers. Any pointers? I checked lidgren but it's for .NET only and hence not an option for me. EDIT: just in case it wasn't clear, the messaging has to be real time hence it's probably going to be over UDP

  • Is there a general rule of thumb for which browsers to optimize your site for?

    - by Christian
    I have a site (recently relaunched it with a new design) that I have put off optimizing for ie7 for far too long. I was just never too worried about it. The site is optimized for ie8-10, Firefox, Chrome, Opera, Safari, etc.. Then I asked myself, is it even worth it? I checked traffic over the last couple months before the relaunch and about 1.3% of the traffic is coming from ie7. So, is there a general cuttoff percentage when you would not optimize for a specific browser?

  • How to prepare WiFi for an on-stage demo?

    - by Jeremy White
    Today at WWDC, Steve Jobs gave his keynote and ended up having a failure on-stage when connecting to WiFi. Google had a similar issue a few weeks ago in the same conference center. Please reference the following article for more information. http://news.cnet.com/8301-31021_3-20007009-260.html I am looking for information on how to best prepare a demo which uses a closed wireless network in front of a large audience. Note that the network will be closed, and will not require internet access. What steps can I take to prevent interference from existing WiFi, Bluetooth, etc? How can I best prevent curious/malicious people from trying to intrude on my WiFi network? I am open to recommendations on specific models of routers.

  • How to connect to a wireless network that has a two word name with a space?

    - by grinan
    Ok, I have searched for some time in earnest for an answer to this question. I have a Beagleboard which has Ubuntu 10.10 Minimal install for Arm running on it. With the default install, minimal tools, no GUI, I am unable to connect to my wireless network. The name of my network is "MYNAME NETWORK". Using a text editor to edit /etc/network/interfaces I can not seem to connect at all. As an experiment, I connected to a friends network, which has a one word name "dystek",and was able to connect with Zero issues, and update and install a full GUI for ubuntu Arm. The problem is that I don't want a full blown gui on the beagleboard, just a minimal install of ubuntu with CLI is all I need or want. Is there anyway to connect to my wireless network via editing the /etc/network/interfaces file. Surely there is... I just don't know how. Right now my interfaces file looks like this: auto lo iface lo inet loopback auto wlan0 iface wlan0 inet static address 192.168.1.200 netmask 255.255.255.0 gateway 192.168.1.1 wireless-essid BARRETT NETWORK wireless-key 46456xxxxxxxx Any help would be appreciated.

  • NetworkManager not populating resolv.conf

    - by Cerin
    I recently upgraded from 11.10 to 12.04, and now NetworkManager isn't populating /etc/resolv.conf when connecting to wireless networks, when it had been working perfectly in 11.10. I'm not seeing any explicit errors in either the NM UI or in syslog. How do I diagnose what's wrong? Edit: If I try to run resolvconf, I get the error "resolvconf: Error: /etc/resolv.conf isn't a symlink, not doing anything." What should it be a symlink to and/or how do I get NM to populate it? This says the symlink should point to /run/resolvconf/resolv.conf, but that file does not exist on my system.

  • Remote location looses connectivity

    - by user24559
    I have a remote location that has constant internet access using DSL. The remote location only has three Linksys cameras that use the internet access with a router. There is no computer on the network. The router is configured to use the DYN.org service to keep the IP address updated if the internet provider assigns a new ip address. The problem I am having is the router after a period of time stops responding to incoming ping requests and the cameras are shown offline. However, if I keep one of the cameras constantly streaming data then the connection to all the cameras works just fine all the time. How can I keep the router from appearing to be sleeping and not responding to incoming requests? The router is the Linksys WRT300N.

  • dnsmasq not running

    - by Yevgeniy M.
    i installed ubuntu 12.04 on a netbook with 16GB SSD. To keep the installation small i used the mini.iso i got from here. Everything worked fine, but i noticed that dnsmasq does not get started by NetworkManager. On a different machine i installed 12.04 from a regular iso and netstat shows dnsmasq running and listening on port 53. NetworkManager.conf look identically on both systems. The line dns=dnsmasq is present. Although i do not really need dnsmasq - name resolution works fine without - i would like to know the reason why dnsmasq is running on one system, but does not run on the other and how i could adjust this behavior. Thx in advance!

  • 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.

    When navigating to some websites (like victorsosea.com, citibank.co.in etc.) on Google Chrome, I get a message that the 'connection to www.site.com was interrupted'. If I try on Firefox, it says 'The connection to the server was reset'. This happens no matter what internet connection I use on my laptop. Be it my home internet or office internet. I have tried using Google DNS address as well but that does not seem to solve the problem. I have been facing this problem randomly for some websites. Kindly let me know how I can resolve the issue.
