  • small Windows network w/ printer issue

    - by user33666
    printer 1 connected to the desktop printer 2 connected to the same desktop that desktop is connected via Cat 5 to a wireless router a notebook is connected to that same router via WiFi The desktop Control Panel has just been reconfigured to share printers. (I assume this means that the desktop will now allow a notebook coming through the router to be able to access the two printers that are presently hooked up via the desktop--am I correct? Is that what it means?) The desktop can still print to either printer. It is presently okay. This notebook/printer relationship is a new configuration. The notebook, however, can't print at all (yet it can access the internet just fine). Any suggestions for it to be able to access the printers and be able to print via the desktop via the router? Thank you for any assistance.

  • PHP: Object Oriented Programming -> Operator

    - by oman9589
    So I've been reading through the book PHP Solutions, Dynamic Web Design Made Easy by David Powers. I read through the short section on Object Oriented PHP, and I am having a hard time grasping the idea of the - operator. Can anyone try to give me a solid explanation on the - operator in OOP PHP? Example: $westcost = new DateTimeZone('America/Los_Angeles'); $now->setTimezone($westcoast); Also,a more general example: $someObject->propertyName Thanks

  • COM(C++) Programming Tutorials

    - by Deep-B
    Hey guys, I was wondering if there're any good sites that deal with learning C++/COM from the ground up? Looking for something like a crash course (two weeks, and not being hypothetical here). Assume knowledge in standard C/C++, or at least not a complete dummy.

  • Monitoring VPN users on my network

    - by Fen0x
    My company runs filters on contents available for browsing and I have to check if everyone is respecting the browsing policies. Recently I have spotted some users activate OpenVPN on their workstations and i have discovered that they connect on port 443 of an external server and then use a proxy to circumvent the company filters. Is there any method to monitor VPN connections on allowed ports or to avoid the connections?

  • How would I find voluntary programming work?

    - by Ben
    While I look for a job, I'd like to do something useful with my time. I have a feeling there must be schools or charities or other worthy organisations that could use some of my time, but I've no idea how to go about finding them. Is there a marketplace for this kind of thing? I live in the UK.

  • Setting up a home network

    - by Mat Richardson
    I'm trying to get my head around how to do this with the equipment I have. Here's how it is.. I have an old laptop that has server 2003 installed on it. This has no wireless NIC, but I have a spare wireless router that I can wire to it. We have a virgin wireless router which provides the home with internet access. What I would like to do it make resources on the server 2003 machine available to the rest of the devices in the home - specifically a couple of laptops running windows 7. Ideally I'd like to be able to use the laptop as a fileserver but maybe also offer application virtualization. In the first instance however, I'd like to create a file server with the laptop and allow connections to it by the other machines. Virtualisation is just a 'nice to have'... Given the hardware I have is this possible? Can you point me in the right direction how to do what I want if this is the case?

  • Best programming based games

    - by Matt Sheppard
    Back when I was at school, I remember tinkering with a Mac game where you programmed little robots in a sort of pseudo-assembler language which could then battle each other. They could move themselves around the arena, look for opponents in different directions, and fire some sort of weapon. Pretty basic stuff, but I remember it quite fondly, even if I can't remember the name. Are there any good modern day equivalents?

  • How do I change careers to become a programmer without spending a lot of money

    - by bgc83
    I'm currently a network engineer, but find myself wanting to get into the world of development. I took a little bit of Java in college, am 27 years old and have been network engineering for 4 years now. I have a mortgage and student loans so going back to school would be difficult. I'm willing to put in however much hardwork is needed around my full time job to learn, but part of me feels I may need actuall schooling to get down some of the advanced concepts. Just looking for a little advice and direction. I have purchased a bunch of the Head First programming books and have begun reading through some of them as I figure out my way into this transition.

  • Mirror network packets from WiFi to Ethernet in an ASUS Router RT N53

    - by fazineroso
    I have an ASUS RT N53 router, running the default firmware (Linux 2.6.22 with busybox and uclibc). I need to capture data packets from some Wi-Fi devices I have connected to that router (iPad and some smartphones), but the router is not forwarding any package coming from Wi-Fi devices to the Ethernet Ports. Any idea how can I proceed? Available tools in the router are iptables (no tee option, though), ebtables, brctl... Currently the ethernet and Wifi devices are forming a bridge: # brctl show bridge name bridge id STP enabled interfaces br0 8000.50465dc06be2 no vlan0 eth1 No ebtables rules: # ebtables -L Bridge table: filter Bridge chain: INPUT, entries: 0, policy: ACCEPT Bridge chain: FORWARD, entries: 0, policy: ACCEPT Bridge chain: OUTPUT, entries: 0, policy: ACCEPT

  • Cannot access internal website after being connected to other network

    - by Dandroid
    I have a client who claim they cannot access their internal website when they have e.g. been out traveling. They have to reset their browser settings every time to be able to get access again. As they live on another continent and timezone it's hard for me to run live tests with them to see what changes in their browser settings. My first guess would be it's some sort of Proxy related issue, but I want to know if there could be other reasons for this? It's not the LAN itself, that we are sure of. It's browser specific only. Edit It's worth mentioning that it only happens when they turn off/restart their computers.

  • Programming practice

    - by exc1z
    I've decided to get some experience working on some project this summer. Due to local demand on market I would prefer to learn Java (Standard and Enterprise Editions). But I can't even to conjecture what kind of project to do. Recently I had some ideas about C. With C I could to contribute to huge Linux projects. I don't mean that my work will be surely commited. I could get the code and practice with it. But C it's not right thing to get good job in my area. In case of JavaSE there is a chance to develop some desktop applications. But thinking about JavaEE I get stuck. I'll be very thankful for answers.

  • How do I get to the bottom of network latency and bandwidth issues

    - by three_cups_of_java
    I recently moved two blocks south. That move moved me from Comcast to Broadstripe (high-speed internet cable providers). Comcast was pretty good. Broadstripe sucks. I called them on the phone, and they basically brushed me off (politely). I want to come to them with some numbers, so I can say more than just "it's really slow". I still have access to my old Comcast service, so I can run the tests using both providers. Here's what I'm seeing with my new Broadstripe service: 1) When I browse to most sites, there is a long delay (5-10 seconds) before the page starts loading in my browser 2) The speed test tell me I have 12 megs down (bullshit) 3) I have a server at my office. I just downloaded some files (using scp on the command line). It said I'm getting 3.5 KB/s I'm an experienced programmer and spend most of my days on the command line and in vim. Networking, however is not a strong point. I've played around with traceroute, but I'm not sure if that's the right tool to use. I have access to servers all over the country (I would just use Amazon EC2 to set up a test server), and I prefer to use Ubuntu for my testing. How can I come up with some hard numbers to show Broadstripe how crappy their service is?

  • Online Game programming in Google App Engine: AI

    - by Hortinstein
    I am currently in the planning stages of a game for google app engine, but cannot wrap my head around how I am going to handle AI. I intend to have persistant NPCs that will move about the map, but short of writing a program that generates the same XML requests I use to control player actions, than run it on another server I am stuck on how to do it. I have looked at the Task Queue feature, but due to long running processes not being an option on the App engine, I am a little stuck. I intend to run multiple server instances with 200+ persistant NPC entities that I will need to update. Most action is slowly roaming around based on player movements/concentrations, and attacking close range players(you can probably guess the type of game im developing)

  • programs hangs during socket interaction

    - by herrturtur
    I have two programs, sendfile.py and recvfile.py that are supposed to interact to send a file across the network. They communicate over TCP sockets. The communication is supposed to go something like this: sender =====filename=====> receiver sender <===== 'ok' ======= receiver or sender <===== 'no' ======= receiver if ok: sender ====== file ======> receiver I've got The sender and receiver code is here: Sender: import sys from jmm_sockets import * if len(sys.argv) != 4: print "Usage:", sys.argv[0], "<host> <port> <filename>" sys.exit(1) s = getClientSocket(sys.argv[1], int(sys.argv[2])) try: f = open(sys.argv[3]) except IOError, msg: print "couldn't open file" sys.exit(1) # send filename s.send(sys.argv[3]) # receive 'ok' buffer = None response = str() while 1: buffer = s.recv(1) if buffer == '': break else: response = response + buffer if response == 'ok': print 'receiver acknowledged receipt of filename' # send file s.send(f.read()) elif response == 'no': print "receiver doesn't want the file" # cleanup f.close() s.close() Receiver: from jmm_sockets import * s = getServerSocket(None, 16001) conn, addr = s.accept() buffer = None filename = str() # receive filename while 1: buffer = conn.recv(1) if buffer == '': break else: filename = filename + buffer print "sender wants to send", filename, "is that ok?" user_choice = raw_input("ok/no: ") if user_choice == 'ok': # send ok conn.send('ok') #receive file data = str() while 1: buffer = conn.recv(1) if buffer=='': break else: data = data + buffer print data else: conn.send('no') conn.close() I'm sure I'm missing something here in the sorts of a deadlock, but don't know what it is.

  • System Center 2012 R2 System Discovery Network Utilization

    - by AtomicReaction
    I'm in charge of a deployment of Microsoft System Center Configuration Manager 2012 R2. Currently, I'm working through the discovery methods and trying to decide how to enable automatic discovery of systems and users. On Microsoft's documentation, they warn that Configuration Manager Automatic Discovery traffic can get pretty significant if you aren't careful in your implementation. Can anyone who has used this give me some information on how much traffic I should expect? We currently have around 1000 computers and 4000 user accounts in Active Directory. Thanks!
