  • Bluetooth on 2.0+

    - by awiden
    I'm doing bluetooth development for connecting with a PC. I've basicly used the BTChatExample and changed the UUID to the standard PC SPP-profile. Trying to close a bluetooth application during a blocking read, by closing the BluetoothSocket will leave the Bluetooth stack in a unusable state. This can only be fixed by disabling and enabling bluetooth and restarting the application. Checking logcat, you can see that some of the internal methods are failing, leaving a open port. Any information on this? First of all there seams to be differences on how bluetooth is implemented on N1 and HTC Legend/Desire both running 2.1, do you know anything about this? Connecting isn't 100% reliable, sometimes I get a warning saying ~PortSystemContext init: FAILED. This leaves bluetooth unusable, and restarting is needed. Am I right in assuming that SPP is the only profile supported for use with the APIs? That's what the docs on the BluetoothAdapter says. I would love to discuss issues on bluetooth with a developer and iron out these bugs so that Android can have good proper BT support it deserves.

  • Jruby and ffi: Function 'xmlFirstElementChild' not found in [libexslt.so]

    On a ubuntu server, with everything installed (checked against another pc where this works just fine) When trying to run warble on one of my jruby projects, I get this error: Function 'xmlFirstElementChild' not found in [libexslt.so] /opt/jruby-1.5.0/lib/ruby/site_ruby/shared/ffi/ffi.rb:112:in `create_invoker' /opt/jruby-1.5.0/lib/ruby/site_ruby/shared/ffi/library.rb:98:in `attach_function' /opt/jruby-1.5.0/lib/ruby/site_ruby/shared/ffi/library.rb:96:in `each' /opt/jruby-1.5.0/lib/ruby/site_ruby/shared/ffi/library.rb:96:in `attach_function' /opt/jruby-1.5.0/lib/ruby/gems/1.8/gems/nokogiri-1.4.2-java/lib/nokogiri/ffi/libxml.rb:116 /opt/jruby-1.5.0/lib/ruby/gems/1.8/gems/nokogiri-1.4.2-java/lib/nokogiri/ffi/libxml.rb:31:in `require' /opt/jruby-1.5.0/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require' /opt/jruby-1.5.0/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:156:in `require' /opt/jruby-1.5.0/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:521:in `new_constants_in' /opt/jruby-1.5.0/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:156:in `require' /opt/jruby-1.5.0/lib/ruby/gems/1.8/gems/nokogiri-1.4.2-java/lib/nokogiri.rb:11 /opt/jruby-1.5.0/lib/ruby/gems/1.8/gems/nokogiri-1.4.2-java/lib/nokogiri.rb:36:in `require'/ /opt/jruby-1.5.0/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:36:in `require' /opt/jruby-1.5.0/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:156:in `require' /opt/jruby-1.5.0/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:521:in `new_constants_in' /opt/jruby-1.5.0/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:156:in `require' [...] all libraries and required gems seem to be there.

  • Serial Communication between Java RXTX and Arduino

    - by SharpBarb
    I'm trying to communicate between my PC (Windows 7 using Netbeans and RXTX) with an Arduino Pro, using the serial port. The Arduino is actually connected to the PC using an FTDI cable. The code is based on the Java SimpleRead.Java found here. Currently the Arduino simply prints out a string when it starts up. My Java program should print the number of bytes that have been read and then print out the contents. The Java program works, sort of... If the string is long (10 bytes or so) the output will get broken up. So if on the Arduino I print Serial.println("123456789123456789"); //20 bytes including '\r' and '\n' The output of my Java program may look something like: Number of Bytes: 15 1234567891234 Number of Bytes: 5 56789 or Number of Bytes: 12 1234567891 Number of Bytes: 8 23456789 I'm thinking it's a timing problem, because when I manually go through the code using the debugger, the result string is always what it should be: one 20 byte string. I've been messing with various things but I haven't been able to fix the problem. Here is the part of the code that is giving me problems: static int baudrate = 9600, dataBits = SerialPort.DATABITS_8, stopBits = SerialPort.STOPBITS_1, parity = SerialPort.PARITY_NONE; byte[] readBuffer = new byte[128]; ... ... public void serialEvent(SerialPortEvent event) { if (event.getEventType() == SerialPortEvent.DATA_AVAILABLE) { try { if (input.available() > 0) { //Read the InputStream and return the number of bytes read numBytes = input.read(readBuffer); String result = new String(readBuffer,0,numBytes); System.out.println("Number of Bytes: " + numBytes); System.out.println(result); } } catch (IOException e) { System.out.println("Data Available Exception"); } }

  • Different versions of JBoss on the same host

    - by Vladimir Bezugliy
    I have JBoss 4 installed on my PC to directory C:\JBoss4 And environment variable JBOSS_HOME set to this directory: JBOSS_HOME=C:\JBoss4 I need to install JBoss 5.1 on the same PC. I installed it into C:\JBoss51 In order to start JBoss 5.1 on the same host where JBoss 4 was already started, I need to redefine properties jboss.home.dir, jboss.home.url, jboss.service.binding.set: C:\JBoss51\bin\run.sh -Djboss.home.dir=C:/JBoss51 \ -Djboss.home.url=file:/C:/JBoss51 \ -Djboss.service.binding.set=ports-01 But in C:\JBoss51\bin\run.sh I can see following code: … if [ "x$JBOSS_HOME" = "x" ]; then # get the full path (without any relative bits) JBOSS_HOME=`cd $DIRNAME/..; pwd` fi export JBOSS_HOME … runjar="$JBOSS_HOME/bin/run.jar" JBOSS_BOOT_CLASSPATH="$runjar" And this code does not depend either on jboss.home.dir or on jboss.home.dir. So when I start JBoss 5.1 script will use jar files from JBoss 4.3? Is it correct? Should I redefine environment variable JAVA_HOME when I start JBoss 5.1? In this case script will use correct jar files. Or if I redefined properties jboss.home.dir, jboss.home.url then JBoss will not use any variables set in run.sh? How does it works?

  • Smack API giving error while logging into Tigase Server setup locally

    - by Ameya Phadke
    Hi, I am currently developing android XMPP client to communicate with the Tigase server setup locally.Before starting development on Android I am writing a simple java code on PC to test connectivity with XMPP server.My XMPP domain is my pc name "mwbn43-1" and administrator username and passwords are admin and tigase respectively. Following is the snippet of the code I am using class Test { public static void main(String args[])throws Exception { System.setProperty("smack.debugEnabled", "true"); XMPPConnection.DEBUG_ENABLED = true; ConnectionConfiguration config = new ConnectionConfiguration("mwbn43-1", 5222); config.setCompressionEnabled(true); config.setSASLAuthenticationEnabled(true); XMPPConnection con = new XMPPConnection(config); // Connect to the server con.connect(); con.login("admin", "tigase"); Chat chat = con.getChatManager().createChat("aaphadke@mwbn43-1", new MessageListener() { public void processMessage(Chat chat, Message message) { // Print out any messages we get back to standard out. System.out.println("Received message: " + message); } }); try { chat.sendMessage("Hi!"); } catch (XMPPException e) { System.out.println("Error Delivering block"); } String host = con.getHost(); String user = con.getUser(); String id = con.getConnectionID(); int port = con.getPort(); boolean i = false; i = con.isConnected(); if (i) System.out.println("Connected to host " + host + " via port " + port + " connection id is " + id); System.out.println("User is " + user); con.disconnect(); } } When I run this code I get following error Exception in thread "main" Resource binding not offered by server: at org.jivesoftware.smack.SASLAuthentication.bindResourceAndEstablishSession(SASLAuthenticatio n.java:416) at org.jivesoftware.smack.SASLAuthentication.authenticate(SASLAuthentication.java:331) at org.jivesoftware.smack.XMPPConnection.login(XMPPConnection.java:395) at org.jivesoftware.smack.XMPPConnection.login(XMPPConnection.java:349) at Test.main(Test.java:26) I found this articles on the same problem but no concrete solution here Could anyone please tell me the solution for this problem.I checked the XMPPConnection.java file in the Smack API and it looks the same as given in the link solution.

  • C compiler cannot create executables when trying to build Binutils

    - by Koning Baard XIV
    I am trying to build Linux From Scratch, and now I am at chapter 5.4, which tells me how to build Binutils. I have binutils 2.20's source code, but when I try to build it: time { ./binutils-2.20/configure --target=$LFS_TGT --prefix=/tools --disable-nls --disable-werror ; } it gives me an error: checking build system type... i686-pc-linux-gnu checking host system type... i686-pc-linux-gnu checking target system type... i686-lfs-linux-gnu checking for a BSD-compatible install... /usr/bin/install -c checking whether ln works... yes checking whether ln -s works... yes checking for a sed that does not truncate output... /bin/sed checking for gawk... gawk checking for gcc...

  • image analysis and 64bit OS

    - by picciopiccio
    I developed a C# application that makes use of Congex vision library (VPro). My application is developed with Visual Studio 2008 Pro on a 32bit Windows PC with 3GB of RAM. During the startup of application I see that a large amount of memory is allocated. So far so good, but when I add many and many vision elaboration the memory allocation increases and a part of application (only Cognex OCX) stops working well. The rest of application stills to work (working threads, com on socket....) I did whatever I could to save memory, but when the memory allocated is about 700MB I begin to have the problems. A note on the documentation of Cognex library tells that /LARGEADDRESSWARE is not supported. Anyway I'm thinking to try the migration of my app on win64 but what do I have to do? Can I simply use a processor with 64bit and windows 64bit without recompiling my application that would remain a 32bit application to take advantage of 64bit ? Or I should recompile my application ? If I don't need to recompile my application, can I link it with 64bit Congnex library? If I have to recompile my application, is it possible to cross compile the application so that my develop suite is on a 32bit PC? Every help will be very appreciated!! Thank in advance

  • What is session management in Java ?

    - by Sarang
    I have faced this question in my Interview as well. I do have many confusion with Session Scope & it management in java. In web.xml we do have the entry : <session-config> <session-timeout> 30 </session-timeout> </session-config> What does it indicate actually ? Is is scope of whole project ? Another point confusing me is how can we separate the session scope of multiple request in the same project? Means if I am logging in from a PC & at the same time I am logging in from another PC, does it differentiate it ? Also, another confusing thing is the browser difference. Why does the different Gmails possible to open in different browsers ? And Gmail can prevent a session from Login to Logout. How is it maintained with our personal web ?

  • strange redefined symbols

    - by Chris H
    I included this header into one of my own: http://codepad.org/lgJ6KM6b When I compiled I started getting errors like this: CMakeFiles/bin.dir/SoundProjection.cc.o: In function `Gnuplot::reset_plot()': /usr/lib/gcc/x86_64-pc-linux-gnu/4.3.4/include/g++-v4/new:105: multiple definition of `Gnuplot::reset_plot()' CMakeFiles/bin.dir/main.cc.o:project/gnuplot-cpp/gnuplot_i.hpp:962: first defined here CMakeFiles/bin.dir/SoundProjection.cc.o: In function `Gnuplot::set_smooth(std::basic_string, std::allocator const&)': project/gnuplot-cpp/gnuplot_i.hpp:1041: multiple definition of `Gnuplot::set_smooth(std::basic_string, std::allocator const&)' CMakeFiles/bin.dir/main.cc.o:project/gnuplot-cpp/gnuplot_i.hpp:1041: first defined here CMakeFiles/bin.dir/SoundProjection.cc.o:/usr/include/eigen2/Eigen/src/Core/arch/SSE/PacketMath.h:41: multiple definition of `Gnuplot::m_sGNUPlotFileName' I know it's hard to see in this mess, but look at where the redefinitions are taking place. They take place in files like /usr/lib/gcc/x86_64-pc-linux-gnu/4.3.4/include/g++-v4/new:105. How is the new operator getting information about a gnuplot header? I can't even edit that file. How could that ever even be possible? I'm not even sure how to start debugging this. I hope I've provided enough information. I wasn't able to reproduce this in a small project. I mostly just looking for tips on how to find out why this is happening, and how to track it down. Thanks.

  • Problems in getting data from CFStreamCreatePairWithSocketToHost

    - by gkedmi
    Hi I'm building an iPhoe app with a socket to a PC app , I need to get an image from this PC app. It's my first time using "CFStreamCreatePairWithSocketToHost".After I establish the socket with "NSOperation" I call CFStreamClientContext streamContext = {0, self, NULL, NULL, NULL}; BOOL success = CFReadStreamSetClient(myReadStream, kMyNetworkEvents,MyStreamCallBack,&streamContext); CFReadStreamScheduleWithRunLoop(myReadStream, CFRunLoopGetCurrent(), kCFRunLoopDefaultMode); then I call CFWriteStreamWrite(myWriteStream, &writeBuffer, 3); // Open read stream. if (!CFReadStreamOpen(myReadStream)) { // Notify error } . . . while(!cancelled && !finished) { SInt32 result = CFRunLoopRunInMode(kCFRunLoopDefaultMode, 0.25, NO); if (result == kCFRunLoopRunStopped || result == kCFRunLoopRunFinished) { break; } if (([NSDate timeIntervalSinceReferenceDate] - _lastRead) MyConnectionTimeout) { // Call timed out cancelled = YES; break; } // Also handle stream status CFStreamStatus status = CFReadStreamGetStatus(myReadStream); } and then when I get "kCFStreamEventHasBytesAvailable" I use while (CFReadStreamHasBytesAvailable(myReadStream)) { CFReadStreamRead(myReadStream, readBuffer, 1000); //and buffer the the bytes } It's unpredictable , sometimes I get the whole picture , sometime I got just part of it , and I can't understand what make the different. can someone has an idea what is wrong here? thanks

  • Why can't perfmon see instances of my custom performance counter?

    - by spoulson
    I'm creating some custom performance counters for an application. I wrote a simple C# tool to create the categories and counters. For example, the code snippet below is basically what I'm running. Then, I run a separate app that endlessly refreshes the raw value of the counter. While that runs, the counter and dummy instance are seen locally in perfmon. The problem I'm having is that the monitoring system we use can't see the instances in the multi-instance counter I've created when viewing remotely from another server. When using perfmon to browse the counters, I can see the category and counters, but the instances box is grayed out and I can't even select "All instances", nor can I click "Add". Using other access methods, like [typeperf][1] exhibit similar issues. I'm not sure if this is a server or code issue. This is only reproducible in the production environment where I need it. On my desktop and development servers, it works great. I'm a local admin on all servers. CounterCreationDataCollection collection = new CounterCreationDataCollection(); var category_name = "My Application"; var counter_name = "My counter name"; CounterCreationData ccd = new CounterCreationData(); ccd.CounterType = PerformanceCounterType.RateOfCountsPerSecond64; ccd.CounterName = counter_name; ccd.CounterHelp = counter_name; collection.Add(ccd); PerformanceCounterCategory.Create(category_name, category_name, PerformanceCounterCategoryType.MultiInstance, collection); Then, in a separate app, I run this to generate dummy instance data: var pc = new PerformanceCounter(category_name, counter_name, instance_name, false); while (true) { pc.RawValue = 0; Thread.Sleep(1000); }

  • grep 5 seconds of input from the serial port inside a shell-script

    - by pica
    I've got a device that I'm operating next to my PC and as it runs it's spitting log lines out it's serial port. I have this wired to my PC and I can see the log lines fine if I'm using either minicom or something like: ttylog -b 115200 -d /dev/ttyS0 I want to write 5 seconds of the device serial output to a temp file (or assign it to a variable) and then later grep that file for keywords that will let me know how the device is operating. I've already tried redirecting the output to a file while running the command in the background, and then sleeping 5 seconds and killing the process, but the log lines never get written to my temp file. Example: touch tempFile ttylog -b 115200 -d /dev/ttyS0 >> tempFile & serialPID=$! sleep 5 #kill ${serialPID} #does not work, gets wrong PID killall ttylog cat tempFile The file gets created but never filled with any data. I can also replace the ttylog line with: ttylog -b 115200 -d /dev/ttyS0 |tee -a tempFile & In neither case do I ever see any log lines logged to stdout or the log file unless I have multiple versions of ttylog running by mistake (see commented out line, D'oh). I have no idea what's going on here. It seems to be a failure of redirection within my script. Am I on the right track? Is there a better way to sample 5 seconds of the serial port?

  • How to make a product catalog in C#?

    - by Ervin
    I need to develop a product catalog (about 4000 products) application, which would be given to clients on CD or DVD. The catalog exists in webpage format using PHP and MySQL. IMPORTANT: the application is given to clients who maight have old PC, old System. For minimal requirements I would put Windows XP and Internet Explorer 6 (if needed). I need the following features: 1 search option (after productID AND after keyword) 2 print option (by selecting multiple products) 3 shopping cart (making a list which will be sent to an email address if there is any Internet Connection on the computer) When I was asked to do it I had 2 days to realise a very basic version, so I took the whole website and exported it in HTML pages, and developed an application in C# which contains an embeded browser. So the whole website is now static and put on a CD. Everything fine so far. Now here are the problems: 1. the search option was realized by parsing the html files and reading the productID or looking for keywords inside of them. Put on a CD it was extremely slow (searching in 600MB of html files). FOR THIS I WOULD NEED A SOLUTION WITH A STATIC DATABASE (USING ACCESS OR SOMETHING) TO HAVE INDEXED ROWS, SO THE SEARCH COULD BE A VERY FAST ONE. 2. the printing option was a simply call of the embeded Internet Explorer print functions. Here are two problems: a) user needs IE7 for printing the website scaled (FIT TO PAGE), otherwise the edges of the page are cut down. b) users of this app does not have even the basic PC usage skills, so they can't set the printing settings, so there will appear in header and footer the page numbers and titles. QUESTION: can I set these settings from CSS for printing? 3. couldn't make a a shopping cart as I don't use a database, so I have static websites and content is inside the HTML. QUESTION: WHICH ARE THE BEST SOLUTIONS FOR THE PROBLEMS DESCRIBED ABOVE? PLEASE ANSWER EVEN IF YOUR ANSWER IS FOR ONE QUESTION ONLY. THANKS

  • Counting computers for each lab

    - by Irvin
    Alright I have a problem with having to count PCs, and Macs from different labs. In each lab I need to display how many PC and Macs there is available. The data is coming from a SQL server, right am trying sub queries and the use of union, this the closest I can get to what I need. The query below shows me the number of PCs, and Macs in two different columns, but of course, the PCs will be in one row and the Macs on another right below it. Having the lab come up twice. EX: LabName -- PC / MAC Lab1 -- 5 / 0 Lab1 -- 0 / 2 Query SELECT Labs.LabName, COUNT(*),0 AS Mac FROM HardWare INNER JOIN Labs ON HardWare.LabID = Labs.LabID WHERE ComputerStatus = 'AVAILABLE' GROUP BY Labs.LabName UNION SELECT Labs.LabName, COUNT(*), (SELECT COUNT(Manufacturer)) AS Mac FROM HardWare INNER JOIN Labs ON HardWare.LabID = Labs.LabID WHERE ComputerStatus = 'AVAILABLE' AND Manufacturer = 'Apple' GROUP BY Labs.LabName ORDER BY Labs.LabName So is there any way to get them together in one row as in Lab1 -- 5 / 2 or is there a different way to write the query? anything will be a big help, am pretty much stuck here. Cheers

  • OpenOffice in Java

    - by user156073
    I need a Java interface to the OpenOffice document conversion which would equal to a manual (Open... and then Save As...) as well as access to the PDF generation. The following are some example of what I want to achieve. 1) Open one type of document (fx. OpenOffice Writer document or Microsoft Office document) onto memory and save it in another supported format. 2) Open one type of document into memory and export it as PDF. I have gone through http://api.openoffice.org but didn't get any material which can help me to get started. I also tried JODConverter but it requires me to run OpenOffice as a service. I wold prefer to include all the core functionality of OpenOffice in one JAR file so that that the user can use my application without installing or running openoffice on their PC. What would be a URL/code snippet from where I can get tutorials to get started? Also do I have to add some JAR files? Will the application work even if I don't have OpenOffice installed on my PC?

  • Network Authentication when running exe from WMI

    - by Andy
    Hi, I have a C# exe that needs to be run using WMI and access a network share. However, when I access the share I get an UnauthorizedAccessException. If I run the exe directly the share is accessible. I am using the same user account in both cases. There are two parts to my application, a GUI client that runs on a local PC and a backend process that runs on a remote PC. When the client needs to connect to the backend it first launches the remote process using WMI (code reproduced below). The remote process does a number of things including accessing a network share using Directory.GetDirectories() and reports back to the client. When the remote process is launched automatically by the client using WMI, it cannot access the network share. However, if I connect to the remote machine using Remote Desktop and manually launch the backend process, access to the network share succeeds. The user specifed in the WMI call and the user logged in for the Remote Desktop session are the same, so the permissions should be the same, shouldn't they? I see in the MSDN entry for Directory.Exists() it states "The Exists method does not perform network authentication. If you query an existing network share without being pre-authenticated, the Exists method will return false." I assume this is related? How can I ensure the user is authenticated correctly in a WMI session?

  • CrystalDecisions.Web reference version changes suddenly when run the webapp

    - by Somebody
    I'm breaking my head with this issue, I have a webapp that has a report using crystal report, in the development pc it works fine, but when copy the same project to another pc, when I load the project (VS 2003) the following msg appears: One or more projects in solution need to be updated to use Crystal Reports XI Release 2. If you choose "Yes", the update will be applied permanently... I choose "Yes" and after that I can see that CrystalDecisions.Web reference has the correct version, and location according to the develpment machine, in this case: 11.5.3300.0. But when run the webapp, I can see when the version and path suddenly changes to: 11.0.3300.0. And when trying to see the report the following error appears: Parser Error Message: The base class includes the field 'CrystalReportViewer1', but its type (CrystalDecisions.Web.CrystalReportViewer) is not compatible with the type of control (CrystalDecisions.Web.CrystalReportViewer). the asp.net has the following: <%@ Register TagPrefix="cr" Namespace="CrystalDecisions.Web" Assembly="CrystalDecisions.Web, Version=11.5.3300.0, Culture=neutral, PublicKeyToken=692fbea5521e1304" %> How is this possible? what's happening here? EDIT This is what I did: the wrong version (11.0.3300.0) was located at: C:\Program Files\Common Files\Business Objects\3.0\managed and the right version (11.5.3300.0) is located at: C:\Program Files\Business Objects\Common\3.5\managed So I just deleted the files of the wrong solution, and I made it work in my new computer, no more errors when running the webapp, the report shows fine. But when try to do the same thing in production server, a different error came out, now an exception: This report could not be loaded due to the following issue: The type initializer for 'CrystalDecisions.CristalReports.Engine.ReportDocument' threw an exception. Any idea what could be causing this error now? Here is the code: Try Dim cr As New ReportDocument cr.Load(strpath) cr.SetDatabaseLogon("usring", "pwding") Select Case rt Case 1 cr.SummaryInfo.ReportTitle = "RMA Ticket" Case 2 cr.SummaryInfo.ReportTitle = "Service Ticket" End Select 'cr.SummaryInfo.ReportTitle = tt cr.SetParameterValue("TicketNo", tn) 'cr.SummaryInfo.ReportComments = comment CrystalReportViewer1.PrintMode = CrystalDecisions.Web.PrintMode.ActiveX CrystalReportViewer1.ReportSource = cr CrystalReportViewer1.ShowFirstPage() 'cr.Close() 'cr.Dispose() Catch ex As Exception MsgBox1.alert("This report could not be loaded due to the following issue: " & ex.Message) End Try

  • Malware - Technical anlaysis

    - by nullptr
    Note: Please do not mod down or close. Im not a stupid PC user asking to fix my pc problem. I am intrigued and am having a deep technical look at whats going on. I have come across a Windows XP machine that is sending unwanted p2p traffic. I have done a 'netstat -b' command and explorer.exe is sending out the traffic. When I kill this process the traffic stops and obviously Windows Explorer dies. Here is the header of the stream from the Wireshark dump (x.x.x.x) is the machines IP. GNUTELLA CONNECT/0.6 Listen-IP: x.x.x.x:8059 Remote-IP: 76.164.224.103 User-Agent: LimeWire/5.3.6 X-Requeries: false X-Ultrapeer: True X-Degree: 32 X-Query-Routing: 0.1 X-Ultrapeer-Query-Routing: 0.1 X-Max-TTL: 3 X-Dynamic-Querying: 0.1 X-Locale-Pref: en GGEP: 0.5 Bye-Packet: 0.1 GNUTELLA/0.6 200 OK Pong-Caching: 0.1 X-Ultrapeer-Needed: false Accept-Encoding: deflate X-Requeries: false X-Locale-Pref: en X-Guess: 0.1 X-Max-TTL: 3 Vendor-Message: 0.2 X-Ultrapeer-Query-Routing: 0.1 X-Query-Routing: 0.1 Listen-IP: 76.164.224.103:15649 X-Ext-Probes: 0.1 Remote-IP: x.x.x.x GGEP: 0.5 X-Dynamic-Querying: 0.1 X-Degree: 32 User-Agent: LimeWire/4.18.7 X-Ultrapeer: True X-Try-Ultrapeers: 121.54.32.36:3279,173.19.233.80:3714,65.182.97.15:5807,115.147.231.81:9751,72.134.30.181:15810,71.59.97.180:24295,74.76.84.250:25497,96.234.62.221:32344,69.44.246.38:42254,98.199.75.23:51230 GNUTELLA/0.6 200 OK So it seems that the malware has hooked into explorer.exe and hidden its self quite well as a Norton Scan doesn't pick anything up. I have looked in Windows firewall and it shouldn't be letting this traffic through. I have had a look into the messages explorer.exe is sending in Spy++ and the only related ones I can see are socket connections etc... My question is what can I do to look into this deeper? What does malware achieve by sending p2p traffic? I know to fix the problem the easiest way is to reinstall Windows but I want to get to the bottom of it first, just out of interest.

  • [WEB] Local/Dev/Live deployment - best workflow

    - by Adam Kiss
    Hello, situation We our little company with 3 people, each has a localhost webserver and most projects (previous and current) are on one PC network shared disk. We have virtual server, where some of our clients' sites and our site. Our standard workflow is: Coder PC ? Programmer localhost ? dev domain (client.company.com) ? live version (client.com) It often happens, that there are two or three guys working on same projects at the same time - one is on dev version, two are on localhost. When finished, we try to synchronize the files on dev version and ideally not to mess (thanks ILMV:]) up any files, which *knock knock * doesn't happen often. And then one of us deploys dev version on live webserver. question we are looking for a way to simplify this workflow while updating websites - ideally some sort of diff uploader or VCS probably (Git/SVN/VCS/...), but we are not completely sure where to begin or what way would be ideal, therefore I ask you, fellow stackoverflowers for your experience with website / application deployment and recommended workflow. We probably will also need to use Mac in process, so if it won't be a problem, that would be even better. Thank you

  • How to install msi on remote machine in msbuild without using psexec?

    - by TS
    I have searched all the custom tasks in Extension Pack and Community Tasks and finally found a task called Msi.Istall in SDC Tasks. But the documentation is bad and causes problems. I get errors regarding the properties passed to the installer. Below is my Install target : `<Target Name="Install"> <!-- Copy the MSI package into remote pc. --> <!--<CreateItem Include="\\grpdev1\Sharing\Build Script\Server Applications\**\*.*"> <Output ItemName="Source" TaskParameter="Include"/> </CreateItem> <Copy SourceFiles="@(Source)" DestinationFolder="\\lta0\c$\TestRemoteInstall\%(Source.RecursiveDir)"/>--> Seems like it looks at my own local pc to install it and says the product is already installed and needs to be removed. How else do i specify the remote machine? Any ideas where I am going wrong? I have also been asked not to use psexec tool or intermediate scripts.. Looking to install directly from msbuild task.

  • Swing GUI using JNI crashes

    - by Div
    Hi, A java swing application(GUI) using JNI code to communicate with native C code. The Swing application launches properly and works fine. The GUI is used to start some customized system level tests(io,memory,cpu) and show their progress. The tests have to be left running at-least overnight to get the results. But, the next morning, GUI crashes and throws following message. Any pointers on source of the issue will be greatly appreciated. Java version: java 1.5 / java 1.6 OS: Solaris 10.
