• What should I know before getting involved in Kinect development?

  - by chossen-addict

  I'm in the final year of my Computer Science degree, and I'm starting to look at what I can work on as a final-year project. I've been looking at creating a Kinect application, but I'm not sure if I have the necessary background to get involved in its development. What should I know before starting Kinect development? Are there areas of programming I should have a background in in order to understand what I need to do to create a Kinect app?

• Why is Linux choosing the wrong source ip address

  - by Scheintod

  and what to do to let it choose the right one? This all happens inside an OpenVZ container: The Host is Debian/Wheezy with Redhat/OpenVZ Kernel: root@mycl2:~# uname -a Linux mycl2 2.6.32-openvz-042stab081.5-amd64 #1 SMP Mon Sep 30 16:40:27 MSK 2013 x86_64 GNU/Linux The container has two (virtual) network interfaces.

EDIT: If I create the route with (thanks to Joshua) ip route add 10.0.0.0/8 dev venet0 src 10.0.1.29 it is working. But according to man ip-route the src parameter should only set the source-ip if this route is chosen. But if this route is chosen then the source-ip would be that anyway.

• Windows XP doesn't like small subnets?

  - by erniedwork

  This totally sounds like a bug to me, because my subnet mask and IP address should be valid by all accounts. My ISP has assigned me a fixed IP address of 65.110.7.20, with a subnet mask of 255.255.255.252. Which sounds about right, because we're trying to set up a router with a /31 network - just 4 ip addresses. But when I try to set this IP and netmask up in Windows XP, I get the following error: "The combination of IP address and subnet mask are invalid. All of the bits in the host address portion of the IP address are set to 0." But they're not all set to 0. That would be a subnet mask of 255.255.255.255. Even then, that too is a valid subnet mask, consisting of a network of 1 IP address. Is there a way around this? A registry hack maybe?

• Updating shared files across computers

  - by murgatroid99

  I have a file server running Windows Server 2008 and a couple of laptops running Windows 7 on a network. There are a large number of files that all users will need access to. My plan is to have the files on both the server and the laptops because the users will need to access the files in places with no Internet access. I also want any changes made to the files on any of the laptops to propagate to the server and then propagate to the other laptops whenever they connect to the network. Should I do this with a scheduled batch script with a few xcopy commands or is there a better way to do it?

• Is it smart to take a year off from school to get experience?

  - by user134147

  firstly I apologize if this question is not appropriate for the site, but I've seen other similar (though slightly deviant) questions on this sight before and I know the people here are the most qualified to answer my question. Anyways, I'm currently between my sophomore and junior years at a 4 year university, and after a bit of deliberation I've decided on computer science as a major (BA, by the way, as a BS would require me to stay at least an extra year the way our program is set up). I've been interested now in programming for a few months and I've developed a passion for it in a very short time. I began learning C++, migrating to Java recently when I learned my school focuses on this language. Now, I should mention that the concept of higher education has never sat well with me, so part of my motivation for wanting to take time off is to truly challenge myself and see what I can accomplish when I actually try at something. The autodidact in me finds it difficult to focus on my passions while trying to keep a high GPA in unrelated classes. However, I understand the times we live in and therefore would plan to complete my degree after this year. So my question is whether or not the skills I learn in a year off from college could justify the time off from school. Unfortunately, I don't believe I know enough yet to gain any professional experience (internship, etc.) so I would mostly focus my time on learning Java and another language, possibly Wordpress (to gain an understanding of web programming concepts as I have not yet decided what field I want to get into, and to make some money to fund my off-year), and to delve into security concepts, which also interest me. I'm hoping I could work on projects, such as simple applications or contributions to open source software during this time to enhance my resume once I do finish school, so I can find a job out of college easier. I do not want to be the new hire who knows nothing beyond the concepts of his Java textbooks. Does anyone have any input about these thoughts of mine, or any ideas for where I should focus my studies or how high I might set the bar for my work? Thanks a lot everyone!

• What is the best appliance you've used?

  - by phuzion

  Post your favorite appliances or "all-in-one" programs. Whether it runs in a virtual machine, or on its own hardware, it all goes. My submission is Untangle. It's an open source network gateway (their term). Essentially, it can run a plethora of things that you may otherwise end up buying another appliance for: Web filtering logging mail spam filtering phishing monitor spyware blocking VPN You name it, it's all there. Best of all, it's mostly free. A few appliances have annual costs due to inherent licensing or subscription costs. If you are looking for a new network perimeter device, definitely check it out. The underlying OS doesn't matter, because it's the application we want to praise, not the OS beneath it.

• Estimates, constraint and design [closed]

  - by user65964

  For your next two software projects (assuming that you're getting programming assignments, otherwise consider the program to find the min and max of a set of rational numbers) estimate how much effort they would take before doing them, then keep track of the actual time spent. How accurate were your estimates? State the requirements, constraint, design, estimate (your original estimate and the actual time it took), implementation (conventions used, implement/test path followed.

• Relating ping to perceived browser GUI response

  - by cvsdave

  We periodically get complaints of poor GUI (browser page) response that we need to explore. I am looking for a quick and cheap first check to see if the issue is network latency, or server performance. Has anyone encountered any discussion of ping time and perceived GUI response? I understand that GUI response is complicated, but it would be nice if we could find or develop a rule of thumb along the lines of "Hmmmm, ping is over 200, it might be network problems". Ideally, this lives in a script on the user's machine so that we can see the latency that they are seeing... (BASH, Linux). A reference to a good discussion page would be a fine answer, as would any recommendation of other source material.

• Windows 7 -Can't get access to shared folder from one computer to another.

  - by Carbonara

  I have 2 windows 7 computers and i'm trying to share a folder (that I want password protection on) outside of the homegroup. Both computers are part of the same workgroup and I have the same user account/password combination on both computers plus I have password protected sharing turned on in the network and sharing centre along with file and printer sharing turned on. On computer 1 I have right clicked and selected that I want the folder shared. When I navigate via the network on computer 2 to computer 1 the shared folder shows up on computer 2 but double clicking on it to open it gives me an alert saying I don't have permission to access it, no option to type in the user name and password (according to the help files I shouldn't even need to type the password in if both computers have the same username/password anyway but would need it if I'm logged in as a different user). It's just a blanket denial of access.

• OpenVPN and brouting issue

  - by JavierMartinz

  I have a Guest XEN Machine in which I want to connect by OpenVPN to other network. But I have this problem: when I want to connect to that OpenVPN I get a lot of TLS handshake errors because I think that the packages did not come rightly. When, at the end, the guest machine achieve to connect (after several tries) I can't ping the other machines of the OpenVPN network. Except sometimes, where if I ping 20 times MAYBE i get ping-answer in 1-2 times. I think that this problem is related about how the HOST Xen machine 'filters' the packages to the bridge. I mean, I think that all the outgoing guest machines packages are good but the incoming traffic to the guests is not recognized well. How could I detect/solve the problem? Im using Debian Linux in both machines

• IIS7.5 website (mostly) inaccessible from the outside world

  - by Force Flow

  On the network firewall, I opened up port 80 and forwarded it to the Windows Server 2008 R2 running IIS 7.5. Port 80 is open in the Windows firewall. On the LAN, the website is accessible without any trouble. When accessed from the outside, I can access it only 3 times every few hours before access to it cuts out from the outside. There aren't any access limits in IIS or the network's firewall as far as I can tell. IIS is running PHP 5.3. The default website has been deleted. The bindings for the website's domain are set for mydomain.com *:80 and mydomain.com 192.168.0.3:80

• How setup federated SQL data to display limited information to a Web server in the DMZ?

  - by Pcav

  I have a SQL server behind a firewall. I need to push some limited SQL 2005 information to a Web Server in the DMZ so that I do not have to let database queries come all the way into the database server on our internal network. I want to push a small amount of dynamic data to a Web server in the DMZ and lock it down so that our hosted website does not need to come into the internal network for information; I want to put a server in the DMZ that will be the only connection allowed to the SQL database. This DMZ server will be the only server that can have any sort of connection to the back-end database so the hosting provider just pull the data from our server in the DMZ...

• what do you use for storage discovery / storage management?

  - by lysdexic

  I am looking for some ideas on what would be the best way to discover and manage network storage. Discovery: Any good tools that will scan hosts and storage devices and report back their findings? Maybe using SNMP or WMI? Management: I'm currently looking at Storage Manager by Solar Winds, but it is a bit pricey. Any good open source projects like this? Just looking for ideas of how to get better visibility into the storage infrastructure on this network. It includes a HP Lefthand Iscsi san and EC VNX san. As well as individual hosts with local storage. Thanks for reading and thanks for any input.

• Macbook not connecting to WIFI

  - by Model Reject

  I have been having this problem all week. My Macbook aluminium can't see my wifi network. I have changed the channel to one that isn't being used by neighbours and my iphone picks it up straight away. In other words, the router is fine. It's just the macbook can't see it. This is driving me nuts if anyone can help... My airport card details... Card Type: AirPort Extreme (0x14E4, 0x8D) Firmware Version: Broadcom BCM43xx 1.0 (5.10.131.36.1) Locale: ETSI Supported PHY Modes: 802.11 a/b/g/n Supported Channels: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 36, 40, 44, 48, 52, 56, 60, 64, 100, 104, 108, 112, 116, 120, 124, 128, 132, 136, 140 Wake On Wireless: Supported The funny thing is that is was intermitent on Saturday. I had to keep restarting router and it worked for about 5 minutes, now it doesn't connect or see it at all. Tried using kisMAC and it can't see network either. Thanks, C

• What interface does python use to implement sockets?

  - by user2738698

  When I programmed in python, I believe I interfaced with the transport layer using sockets. If python was programmed by humans, they must have used an interface that was "lower" than sockets, to provide us with the interface to sockets. I assume firewalls, also programmed by humans, use interfaces of lower layers in the same manner, so is there a way to access such lower layers, in terms of programming?

• Central Storage for windows user accounts homedirs .. hardware/software needed?

  - by mtkoan

  We have ~120+ users in our network, and are endeavoring to centralize logon authentication and home directory storage server-side. Most of the users are Windows 2000/XP machines, and a few running Mac OS X. Ideally the solution will be open-source-- can this all be managed from a Linux server running LDAP and Samba? Or would a hacked-NAS Box with a FreeNAS or similar suffice? Or is Micro$oft's Active Directory really the preference here. Is it viable to store PST files on this server for users to read from and write to? They are very large ~1.5gb. We have no mail server (or money) capable of Exchange or IMAP, only an old POP3. What kind of hardware horsepower and network architecture should we have for this kind of thing?

• Separate 2 networks with 1 Windows Server

  - by SamuGG

  The situation is: I have 1 router 192.168.1.1, 1 switch, 1 windows server and a basic LAN of devices accessing it. I need to split into 2 separate LANs with full Internet access each, but isolated from each other. Given that, the server is a Windows Server 2008 R2 with 2 NICs: NIC1: 192.168.1.2 NIC2: 192.168.2.2 The router has no dhcp configuration. Please, can anyone explain gracefully, step by step, what do I need to do? What would be the 2 NICs full configuration? What services do I need to install? I don't want devices on either network to see devices on the other network, they must be completely separate. I guess I'm missing the routing procedure step, but I have no idea how is that done. For example: tell the server that devices with gateway 192.168.2.2 must send traffic for internet to 192.168.1.1 router. Thanks in advance.

• Port forwarding using IP Tables

  - by Darider

  I have a server with a LAN facing address of 192.168.5.100 (eth0) and another LAN facing address of 192.168.6.6 (eth1). On this server I have a Virtualbox instance of fedora running an apache webserver (on port 8080) with a bridged interface to eth1 on the host server with address of 192.168.6.7 Users on the 192.168.6.x network can access the Webserver on the Vbox instance (192.168.6.7) with no problems. My question is what kind of iptables entries or commands should be made/executed so as to allow for users on the 192.168.5.x network to access the webserver on the vbox instance. (I'm hoping their url can be something like: http://192.168.5.100:8080)

• 12.04 Booting into Terminal

  - by user170796

  To preface this, I would like to say that I am completely new to Ubuntu and have essentially zero programming experience/experience working with command line and terminal. I installed Ubuntu because I would like to get into programming. If you could provide me with the simplest instructions possible, I would be grateful. I have a Lenovo Ideapad Y500 (Intel i7, NVidia GT 750m, 1TB HDD, 16GB SSD cache, 8GB RAM) with Windows 8 on it. Using a Live CD, I installed Ubuntu 12.04 onto a 75 GB partition. During the installation, I kept all default settings except for one thing; I decided to encrypt my home folder, and so checked the corresponding box. The installation completed, and I restarted. Once I restarted, I saw the options "Ubuntu, with Linux 3.2.0-23-generic" "Ubuntu, with Linux 3.2.0-23-generic (recovery mode)" "Memory test (memtest86+)" "Memory test (memtest86+, serial console 115200)" "Windows Recovery Environment (loader) (on /dev/sdb3)" "Windows 8 (loader) (on /dev/sdb5)" "System Setup" I chose the first option, and was directed to a screen with the Ubuntu logo and the row of five dots below that change from orange to white. Then, I was brought to a full screen terminal that prompted me to login, which I did. I saw no option to boot into GUI at all, and am lost. I've been searching around and have tried the "startx" command to no avail. Should the command have some sort of context or something? I've also tried selecting the recovery mode option from the boot manager. I've tried the resume option from the following menu, which eventually just shuts down the computer after displaying a lot of scrolling text that's too fast for me to read. I've also tried the failsafex mode from the recovery mode menu, which only brings up a terminal box at the bottom of the window that covers the entire bottom part of the screen. Commands won't work in this window. When I try to access Windows 8, I get a message saying that the EFI file path was not specified or something along those lines. I had to enable Secure Boot in order to access Windows 8 (I had disabled it to be able to boot from the Live CD), which is functioning normally. I am at a complete loss for what to do. Any help will be extremely appreciated. EDIT: Bonus question! If you could figure out a way for me to boot to Windows 8 without having to enable Secure Boot, it would save me a lot of trouble. I can deal with switching every time, but I'd rather not have to.
