  • How to detect an iPhone connecting a network?

    - by JayCrossler
    I've noticed through watching Wireshark that when an iPhone connects to a wifi network, it sends out a few IGMP/MDNS packets to 224.0.0.251 (LAN broadcast, I think). Is there any easy way to watch for these packets and then either run a script or send an event? Or, is the best way to just run a packet sniffer? Any simple ones that can send events or execute curl commands when a filter is triggered? When I run nc -u -l 5353 I get: My-Name-iPhonelocal??? x???)?? ??cc^C Can I do something like: nc -u -l 5353 | grep iPhonelocal | execute command...

  • MapReduce programming system in java-actionscript

    - by eco_bach
    Just finished reading ch23 in the excellent 'Beautiful Code' http://oreilly.com/catalog/9780596510046 on Distributed Programming with MapReduce. I understand that MapReduce is a programming system designed for large-scale data processing problems, but I have a hard time getting my head around the basic examples given and how I might apply them in real world situations. Can someone give a simple example of MapReduce implemented using either java, javascript or actionscript?

  • non-interactive ssh sudo... prompts for the password in plain text

    - by Iain
    I'm running some non-interactive ssh commands. The ssh authentication is taken care of fine through the ssh agent, but if I run a command that requires sudo then the password prompt in my terminal is plain text. For example: ssh remotemachine "sudo -u www mkdir -p /path/to/new/folder" will prompt me for the password in plain text. Does anyone know how I can get it to use the normal secure prompt or that I can pass the password via a switch? (as then I can set up a secure prompt on this side before I send the command) Any help is much appreciated.

  • Per process I/O accounting on AIX

    - by ipozgaj
    Is there a way of getting per process I/O statistics on AIX, i.e. to get current disk I/O rate of a process? Commands like iostat, nmon, topas etc. can't display such data. Filemon also doesn't help. Actually, what I would need is something much like iotop(1) command on Linux. Update: it seems there is no builtin command(s) to do this. I will most probably make my own by using the SPMI API.

  • Batch file to open multiple cmd prompts

    - by JHarris
    I am trying to write a batch file that will automate the following manual process: Open a new cmd prompt (prompt1) Run a bat file (b1) Run a program (that will continue to run) Minimize prompt1 Open a new cmd prompt (prompt2) Run a bat file (b1) Run a different program (that will continue to run) Minimize prompt2 I've found ways to open multiple instances of cmd to run different things, but after I've run the first thing (b1), I then need to run a program in that same cmd window. I currently have start /min cmd /k C:\Users\db2admin\python_environment\Scripts\activate.bat start /min cmd /k C:\Users\db2admin\python_environment\Scripts\activate.bat This opens the two windows and runs the bat, great, but now I need to execute another command (running a python file) in each of the cmd windows. How do I send commands to each prompt?

  • 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?

  • Transfer of directory structure over network

    - by singh
    I am designing a remote CD/DVD burner to address hardware constraints on my machine. My design works like this: (analogous to a network printer) Unix-based machine (acts as server) hosts a burner. Windows-based machine acts as client. Client prepares data to burn and transfers it to the server. Server burns the data on CD/DVD. My question is: what is the best protocol to transfer data over the network (Keeping the same directory hierarchy) between different operating systems?

  • check whether fgets would block

    - by lv
    Hi, I was just wondering whether in C is it possible to peek in the input buffer or perform similar trickery to know whether a call to fgets would block at a later time. Java allows to do something like that by calling BufferedReader.ready(), this way I can implement console input something like this: while (on && in.ready()) { line = in.readLine(); /* do something with line */ if (!in.ready()) Thread.sleep(100); } this allows an external thread to gracefully shutdown the input loop by setting on to false; I'd like to perform a similar implementation in C without resorting to non portable tricks, I already know I can make a "timed out fgets" under unix by resorting to signals or (better, even though requering to take care of buffering) reimplement it on top of recv/select, but I'd prefer something that would work on windows too. TIA

  • What is the difference between the Control.Enter and Control.GotFocus events?

    - by jameswelle
    This may be a basic question, but I have to admit I've never truly understood what the difference between the Control.Enter and Control.GotFocus events is. http://msdn.microsoft.com/en-us/library/system.windows.forms.control.enter.aspx http://msdn.microsoft.com/en-us/library/system.windows.forms.control.gotfocus.aspx Is it a differentiation between capturing keyboard or mouse input or something else?

  • trouble setting node['chef-client']['interval']

    - by atiniir
    I've searched many places and haven't get found the answer to this, I suspect I'm missing something either fundamental or basic (maybe both) I'm using the chef-client::windows_service recipe and trying to set the interval and can't seem to sort it out. I've tried at the role level with: { "defaults": { "chef_client": { "interval":15 } }, "overrides":{ } } and at the node level with: { "chef_client": { "interval":25 }, "tags":[] } but the interval on the node is still 1800 (default)

  • 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)

  • Please summarize how to implement node base licensing

    - by user294896
    Currently a user makes a purchase and then a license is generated and sent to that user, but the license isn't tied to a physical computer so there is nothing to prevent the user sharing the license with someone. I heard people talk about creating a license tied to the mac address of the computer, so the license only works on that computer. Now I know how to get the mac address in code but I dont understand how I can do this step when they first make the purchase on the web, so please what is the basic algorithm for node locked licenses ?

  • Windows Command queue?

    - by Stefano
    i'm thinking if does exist some kind of software that can put in a queue a bunch of windows commands... for example i can say to first copy some file somewhere, then rename those, then delete the old files, then edit one of them etc.... without waiting the effective execution of any of those passages.... this could be useful when copying big files that take a lot and i don't want to sit in front of the computer keeping the eyes on the progress bar... does exist anything like this?

  • What can you do in C without "std" includes? Are they part of "C," or just libraries?

    - by Chris Cooper
    I apologize if this is a subjective or repeated question. It's sort of awkward to search for, so I wasn't sure what terms to include. What I'd like to know is what the basic foundation tools/functions are in C when you don't include standard libraries like stdio and stdlib. What could I do if there's no printf(), fopen(), etc? Also, are those libraries technically part of the "C" language, or are they just very useful and effectively essential libraries?

  • Authoritative Excel range syntax reference

    - by olefevre
    Sorry if this has been asked before but I can't find it. I am looking for an authoritative description of all valid strings that can be used as a reference, e.g., "A1:C5", "$A:$A", $A2" etc etc. That seems a pretty basic thing yet I've wasted hours trying to locate it. All I can find is a swamp of "helpful" examples but no reference.

  • Arguments to convince to switch from CVS to SVN

    - by ereOn
    Hi, The UNIX department of my company currently uses CVS as source-version control system. They use it in a very strange way: different repositories for development/testing/production code (for the same project), no one tags anything, weird directory architecture, and so on. The system has been set for ages but now, I have an opportunity to organize a meeting where I have to suggest changes. I'd like to make them change from CVS to SVN (Mercurial or Git might be even better, however I can't really recommand using a system I don't know well, and switching to SVN will already be a great step forward). I don't have much experience with CVS so I can't compare them efficiently: I just know it doesn't support atomic operations and that it is deprecated. What killer arguments would you use to convince my collegues to do the switch ? Thank you very much.

  • Maintaining Logging and/or stdout/stderr in Python Daemon

    - by dave mankoff
    Every recipe that I've found for creating a daemon process in Python involves forking twice (for Unix) and then closing all open file descriptors. (See http://www.jejik.com/articles/2007/02/a_simple_unix_linux_daemon_in_python/ for an example). This is all simple enough but I seem to have an issue. On the production machine that I am setting up, my daemon is aborting - silently since all open file descriptors were closed. I am having a tricky time debugging the issue currently and am wondering what the proper way to catch and log these errors are. What is the right way to setup logging such that it continues to work after daemonizing? Do I just call logging.basicConfig() a second time after daemonizing? What's the right way to capture stdout and stderr? I am fuzzy on the details of why all the files are closed. Ideally, my main code could just call daemon_start(pid_file) and logging would continue to work.

  • User and Key Press Issues with Putty

    - by DizzyDoo
    Ubuntu Server newbie here, got some annoying issues with remote accessing my box with Putty. When I create a user and then login as that user, the terminal always starts with just '#' and not 'user@hostname:~#' which isn't useful where I want to see where I've changed directory too, like I can normally. Also, when logged in as a user, I can't press the cursor keys to move the caret (blinking thing) around, or press up to see previously executed commands. Instead it gives me this representation of the button pressed: ^[[D ^[[A ^[[B ^[[C. Pressing Delete, too, gives me ^[[3~. This is all strange to me, because when logged in as root, it all works fine. I'm hoping this is just something I've accidentally changed in Putty, or added the user wrongly, or perhaps just got caps lock on. Thanks.

  • Ubuntu 13.10 has no Suspend or Hibernate Options

    - by Charlie Davies
    I have a Lenova Yoga 2 Pro, and I have Ubuntu 13.10 installed. I am having some issues setting the power functions. At the moment I can not suspend or hibernate the laptop. So from Gnome 3.10 I have the option to Log Out, Shutdown & Restart. No option for Suspend / Hibernate. Weirdly however I can use these commands to get the right behaviour sudo pm-suspend sudo pm-hibernate So the laptop knows how to do this, it just is not giving me the option and also when I set "Close screen lid" to suspend, well nothing happens. It feels like there is a "connection" not being made.
