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

    - by jwandborg
    Whenever I click "Backup now" in the Backup GUI, the smaller "Back Up" window opends, and after a while I get the following error message: Traceback (most recent call last): File "/usr/bin/duplicity", line 1359, in with_tempdir(main) File "/usr/bin/duplicity", line 1342, in with_tempdir fn() File "/usr/bin/duplicity", line 1202, in main action = commandline.ProcessCommandLine(sys.argv[1:]) File "/usr/lib/python2.7/dist-packages/duplicity/commandline.py", line 942, in ProcessCommandLine globals.backend = backend.get_backend(args[0]) File "/usr/lib/python2.7/dist-packages/duplicity/backend.py", line 156, in get_backend return _backends[pu.scheme](pu) File "/usr/lib/python2.7/dist-packages/duplicity/backends/cloudfilesbackend.py", line 70, in __init__ self.container = conn.create_container(container) File "/usr/lib/python2.7/dist-packages/cloudfiles/connection.py", line 250, in create_container response = self.make_request('PUT', [container_name]) File "/usr/lib/python2.7/dist-packages/cloudfiles/connection.py", line 189, in make_request response = retry_request() File "/usr/lib/python2.7/dist-packages/cloudfiles/connection.py", line 182, in retry_request self.connection.request(method, path, data, headers) File "/usr/lib/python2.7/httplib.py", line 955, in request self._send_request(method, url, body, headers) File "/usr/lib/python2.7/httplib.py", line 989, in _send_request self.endheaders(body) File "/usr/lib/python2.7/httplib.py", line 951, in endheaders self._send_output(message_body) File "/usr/lib/python2.7/httplib.py", line 811, in _send_output self.send(msg) File "/usr/lib/python2.7/httplib.py", line 773, in send self.connect() File "/usr/lib/python2.7/httplib.py", line 1154, in connect self.timeout, self.source_address) File "/usr/lib/python2.7/socket.py", line 571, in create_connection raise err error: [Errno 101] Network is unreachable I use Rackspace CloudFiles as a storage backend, last backup was 3 days ago (successful.

    Is it possible to swap two numbers between two sim cards (I am just got an new phone and it is using a micro sim) And I have a old number that I want to use but it is on standart sim card. Is it possible to swap the numbers between the cards using a SIM Card reader. What software and hardware should I use? Note: I have talked with my provider but I have to cancel my old numbers contract but I like it and do not want to pay the remaining period of the contract to turn it in to PayAsYouGo and then swap ..

  • Netdisco for Ubuntu server

    - by BrNathan
    Has anyone had luck installing netdisco through apt-get? I couldn't get it to work. I tried netdisco-frontend, netdisco-backend, netdisco-common, netdisco-installer. I used the command: sudo apt-get install netdisco-common netdisco-frontend netdisco-backend Everything installed fine, but I can't get it running. It doesn't seem to have install to /usr/local/netdisco/. I have looked all over the internet and there doesn't seem to be an easy way to do this. I use server 12.04. Thanks!

  • Few GUI problems with minimal install

    - by Toki Tahmid
    I installed a minimal Ubuntu with a complete functional GUI, but facing a few problems. nm-applet's icon won't show in the notification area, but I can connect to wired internet fine. I am not able to configure my wireless or VPN this way. gksu's authentication screen is different from the usual graphical authentication - the screen turns gray as usual, but there are more options like save password for this session or keyring. And most importantly, it won't accept my password no matter what. And lastly, Gwibber seems to install no matter what, but there's not a single package in my knowledge that I installed has anything related to Gwibber. I would welcome any help regarding these three issues. I did not mention what packages I installed, because the list is long, but I will do so if anyone requests. Thank you in advance!

  • 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

  • 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

  • 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.

  • 12.04, 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.

  • SharePoint Designer not syncing consistently

    - by normalocity
    I've got a user who uses SharePoint Designer to maintain an internal intranet site. When syncing (remote-to-local) it appears to work at first, but usually hangs about 2-3 minutes into the sync, when he's syncing it to a sub-folder of his "My Documents". In this case, his "My Documents" is stored on a network share/profile. When I do the same thing, it works for me. The difference? My "My Documents" folder is locally stored. In other words, he's syncing from the remote server, into a network share. I'm syncing from the remote server, into a local drive. Any idea why having the sync destination on a network share, vs. a local drive would cause this? When it locks up, we can navigate to his "My Documents" folder still - so I don't believe that we're loosing connection to his drive - unless perhaps the connection is intermittent, and SharePoint Designer isn't re-trying the sync.

  • 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.

  • Best strategy (tried and tested) for using Box2D in a real-time multiplayer game?

    - by Simon Grey
    I am currently tackling real-time multiplayer physics updates for a game engine I am writing. My question is how best to use Box2D for networked physics. If I run the simulation on the server, should I send position, velocity etc to every client on every tick? Should I send it every few ticks? Maybe there is another way that I am missing? How has this problem been solved using Box2D before? Anyone with some ideas would be greatly appreciated!

  • 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.

  • Is it possible to keep nm-applet running between invocations of WM startup?

    - by serverninja
    I am using nm-applet to interface with NetworkManager, running xmonad as a window manager. My X sessions (including nm-applet) are set up with a /usr/local/bin/xmonad.start script. My question is, how can I keep nm-applet running in the background as long as X is running, but not necessarily xmonad? As mentioned above, it is being started with xmonad (and dying with it when xmonad is restarted, etc). I am using gdm to manage my X sessions, and I'm running 10.10. Where's a good place to start nm-applet to suit my particular needs? I need to remove it from the control of xmonad, but don't know where to start it otherwise. Any help, tips, etc appreciated. Edit: problem seems to be with how I have integrated xmonad. I have the session script as a file in /usr/share/xsessions/xmonad.desktop with the following contents: [Desktop Entry] Encoding=UTF-8 Name=XMonad Comment=Lightweight tiling window manager Exec=/usr/local/bin/xmonad.start Icon=xmonad.png Type=XSession /usr/local/bin/xmonad.start contains the following: #!/bin/bash xrdb -merge ~/.Xresources xcompmgr -c & trayer --edge top --align right --SetDockType true --SetPartialStrut true --expand true --width 8 --heighttype pixel --height 18 --transparent true --alpha 0 --tint 0x000000 & gnome-settings-daemon & gnome-screensaver & if [ -x /usr/bin/nm-applet ] ; then nm-applet --sm-disable & fi /usr/bin/urxvtd -q -o -f & eval `ssh-agent` & if [ -x /usr/bin/gnome-power-manager ] ; then sleep 1 gnome-power-manager & fi /usr/bin/gnome-volume-control-applet & exec xmonad The question is how do I integrate xmonad, gdm, X, etc in such a manner to replicate the behavior I currently have except with nm-applet (and possibly other programs) running whether or not xmonad is?

  • Advice on developing a social network [on hold]

    - by Siraj Mansour
    I am doing research on assembling a team, using the right tools, and the cost to develop a highly responsive social network that is capable of dealing with a lot of users. Similar to the Facebook concept but using the basics package for now. Profile, friends, posts, updates, media upload/download, streaming, chat and Inbox messaging are all in the package. We certainly do not expect it to be as popular as Facebook or handle the same number of users and requests, but in its own game it has to be a monster, and expandable for later on. Neglecting the hosting, and servers part, i am looking for technical advise and opinions, on what kind of team i need ? how many developers ? their expertise ? What are the right tools ? languages ? frameworks ? environments ? Any random ideas about the infrastructure ? Quick thoughts on the development process ? Please use references, if you have any to support your ideas. Development cost mere estimation ? NEGLECTING THE COST OF SERVERS I know my question is too broad but my knowledge is very limited and i need detailed help, for any help you can offer i thank you in advance.

  • Realtek RTL8168/8111E onboard NIC not recognized - the everlasting problem?

Or is this a plaque I have to carry forever?

  • 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.

  • How do I know if my serial adapter card is working?

    - by Ingram
    I just installed a 2 port serial adapter in my Ubuntu 10.10 system, then I tried following this tutorial that I used on my old system to connect to a cisco router (my old system had an onboard serial adapter, and the tutorial worked just fine). I can't get my system to connect to the cisco router, so I'm wondering if the card even works in Ubuntu. How can I tell if the card actually works with Ubuntu? #dmesg | grep tty [ 0.000000] console [tty0] enabled [ 0.358667] serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A [ 0.358994] 00:0c: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A [ 0.359128] ttyS1: detected caps 00000700 should be 00000100 [ 0.359132] 0000:03:00.0: ttyS1 at MMIO 0xfeafd000 (irq = 16) is a 16C950/954 [ 0.359191] ttyS2: detected caps 00000700 should be 00000100 [ 0.359195] 0000:03:00.0: ttyS2 at MMIO 0xfeafd200 (irq = 16) is a 16C950/954

  • 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 do I have to reconnect my usb router cable?

    - by Searock
    I have a Iball Baton ADSD2+ Router. It's working fine but the problem is when I boot into Ubuntu I have to unplug the usb cable and then plug it again, then it starts working. Why do I have to re connect my usb cable? Let me know if you need more details. Edit : I am using a direct connection. I mean to say I don't have to enter a username or password. I am connected to internet as soon as I start my router. The problem is if I start my router before my computer I have to re connect my usb cable. Thanks.

  • 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!

  • Wireless BMC4311 driver install

    - by user113910
    Exasperated with Ubuntu 12.04 and BCM4311 driver. HP2133 (was SUSE 10) Installed 12.04 in March. It ran well until November with no updates) then updates killed my wireless controller. Trolled forums & other for fix. Tried sudo -apt-get ing & gedit ing. Finally got it working (on full update with STA driver) Hwew!—thought that was it, only to fail again after 3-4 days. Tried all the fixes again but sudo -apt-get ing & gedit ing does not fix. I'm not without experience either: first 'boot-loader' I/P from 20 switch panel, seq to 4096 bit core-store: run to I/P larger processes from paper tape reader. Gone thru acoustic-coupled networks-to-billboards (before 'the net') pre-DOS, DOS, Windows 3.1 & all the others. This is a tough problem. Any advice?
