• FTP - way to programatically determine time remaining or bytes transfered?

  - by ciaranarcher

  Hi all I want to make an FTP connection (ideally using Coldfusion 8, but Java is fine too) that will copy a file to a remote server. Crucially however, I want to know how many bytes have been transferred so I can give some feedback to the user. Is this possible, and if so what FTP API would you recommend as I understand the Sun implementation may be a bit lacking. Thanks in advance! PS: I could have another process/thread poll the file size on the destination machine via a web service call while the file is being transferred but it's not ideal. Getting it through FTP API would be the neatest solution.

• ftp connects but files aren't visible browsing

  - by YsoL8

  Hello If this should be on that other site, please don't shoot me, as I can't remember the name or the url. I have an ftp account in Dreamweaver that connects to the remote site and appears to be uploading files as normal. But when I browse to the location I can't see any new files or changes to the index page. (I've uploaded index.php and connect.php). I'm getting a 404 page. I suspect the host directory is wrong, but looking at the file tree, I can't see the folder I'm supposed to be using, so I'm uploading to the apparent site root. Any guidance on this?

• Get binary data from audio impulses

  - by Timo

  I have IR sensor which have TRS plug and I can record my remotes signals into audio. Now I want to control my computer with TV remote, but I don't have any clue how to compare audio input with pre-recorded audio. But after I realized that these audio waves contains only some kind data (binary) I can turn these into binary or hex, so it is much easier to compare. Waves look just like this: http://i.imgur.com/lCIyl.png And this: ttp://i.imgur.com/goJ6d.png These are records of "OK" button, sometimes there are some impulses on right channel too and I don't know why, it seems like connections in sensor are damaged maybe. Ok thats not matter, anyway I need help with python program which read these impulses and turn these into binary, in realtime from audio input(mic). I know it's sounds like "Do it for me, while I enjoy my life", but I don't have experiences with sound transforming/reading... I've looking for python examples for recording and reading audio, but unsuccessfully.

• Applet in client-server infrastructure

  - by Andrey

  Hello! I have a general question concerning client-server design. We have a Java server with Spring, a GWT client program and some HTTP-servlets for our site. At the moment we also want to develop an applet which would communicate with that server in such a way GWT-client and site requests do. Is it a good idea to communicate with the server from applet by RMI? I.e. to create some Remote services, register them with Spring and call them from applet? Thanks in advance!

• How to set up Node server for production on own machine?

  - by Matt Hintzke

  This must be a pretty basic thing to do, but I cannot find any good guide on how to do it on the internet. I only find how to set up a development environment for Node. I want to be able to forward my R-Pi's port 80 to my Node server, which I want to obviously listen on port 80. How can I close the native port 80 so that I can let me Node server listen on that port. Ultimately, I want to be able to access my pi from any remote location. I know how to set up a static IP and forward the port on my router, but now how do I allow Node into port 80?

• select GUI on windows (wxPy vs pyQt)

  - by Golovko

  Hello! We are plan to create an application for monitoring and configuring our service (which is running on remote server). After long time discuss, we decide for python as pl for our app, because we love and know python (better, than english, really). but we don't know, what GUI toolkit preffered for our aims. We need fast (for development and running) app, which users are admins, mainteners and account managers. There is two GUI toolkit for python, which we know: wxPython and pyQT. Anybody have arguments pro et contra candidat? And maybe peoples know commercial applications, running in this products (only python version of toolkits)? Links are desirable. Thanks, and excuse my english.

• Do you know any build systems with decent support for parallelization?

  - by dahpgjgamgan

  Hi, I am looking for a build system (working on ms windows) that has good support for parallelization of tasks/targets (or whatever you call them). To be more specific - during build (that is initiated on MS Windows machine) I need to copy source files to a number of different machines (which are not necessarily running Windows) and start a remote job on each of them - and I really like to do that on all machines at once. Does anyone know a build system that's capable of executing such a task in parallel. From what I googled, the options currently available are: -j switch in make - but i don't know if nmake supports this -some custom nAnt tasks -msbuild has some form of support for parallelization - seems similiar to make (meaning you don't specify what to do in parallel, just specify that it would be nice to build things that way) -fake (f# make) is written in functional programming language which are known to have good parallelization support - but I'm not very skillful in functional programming area. Any other solutions I could explore?

• acts_as_ferret with multiple hosts

  - by Nick

  I've got everything working with ferret and acts_as_ferret for development (or localhost DRb), but I can't get my multiple host deployment working. All of the remote systems get ECONNREFUSED when accessing the port. On the ferret server, the daemon is listening on localhost only despite the configuration listing the FQDN as the host. I also tried switching to a UNIX socket to share data between the ferret DRb daemon and the app code but it too gets ECONNREFUSED. (The socket is available to all of the machines via an NFS mount). Is there a better way to do this or should I be looking for another search indexer? Thanks.

• An RMIPRoxyFactoryBean factory in Spring?

  - by Robert Munteanu

  I'm currently using a Spring RmiProxyFactoryBean to access remote services. Since requirements have changed, I need to specify at runtime a different host - there can be many of them - , but the remoteServiceInterface and the non-host components of the remoteServiceUrl remain the same. Conceptually speaking, I'd see a bean definition similar to: <bean class="org.springframework.remoting.rmi.RmiProxyFactoryBeanFactory"> <property name="serviceInterface" value="xxx"/> <property name="serviceUrl" value="rmi://#{HOST}:1099/ServiceUrl"/> </bean> which exposes a Object getServiceFor(String hostName); Is there such a service available with Spring? Alternatively, do you see another way of doing this? Please note that the host list will not be known at compile or startup time, so I can't generate it in the xml file.

• Through Java, make a call to Javascript functions on networked device?

  - by stjowa

  I am doing device monitoring on a networked system. I need to know how to make Javascript calls on that device via its IP address to get certain status information (this device's status is only available through Javascript APIs, not SNMP, etc). I am working in Java. ADDED: The specific device is an Amino set-top-box. It has what it calls JMACX: JavaScript Media Access Control Extensions API specification. It allows you within an HTML document to use that API to get MUCH information about the device (cpu usage, channel info, remote-control options, etc.). I need to get this information within a Java program for specific monitoring purposes. Perhaps possible with HTTP requests? Any input would be greatly appreciated. Thanks, Steve

• php/ssh2 script does not display the stdout to $stream

  - by kamal

  The following php script works for simple linux commands, like ps -ef , but when i use ./dstat -t -a , it seems to hang and i dont get the prompt back on my local machine. Kep in mind that all commands are executed over ssh on a remote host: <?php $target = time() . '_' . 'txt'; if($ssh = ssh2_connect('10.1.0.174', 22)) { if(ssh2_auth_password($ssh, 'root', 'kmoon77')) { //$stream = ssh2_exec($ssh, 'whoami'); $sCommand = 'dstat -a'; //$sCommand = 'ps -ef'; $stream = ssh2_exec($ssh, $sCommand); //$stream = ssh2_exec($ssh, 'pwd'); stream_set_blocking($stream, true); $data = ''; while($buffer = fread($stream, 4096)) { $data .= $buffer; } //fclose($stream); echo $data; // user } } ?>

• protecting applet code against hackers

  - by CodeMed

  I have a Java application that I am considering releasing over the web as an applet. I am concerned about java-savvy end users being able to somehow view the source code, given that my web server would be sending the code to their remote jvm when they try to use the applet. What precautions can be taken to ensure that end users are never able to directly view source code of an applet? I am hoping that release as an applet might somehow protect the privacy of the code more than releasing an application with downloadable jars that the user could just unzip. Is this true?

• Does @import in CSS result in additional http requests?

  - by Mo Boho

  I have an ecommerce site that has about 8 CSS files linked from the header - resulting in 8 separate http requests to the server. I consolidated all the CSS files into 1 big one, resulting in a 67kb (!) file - to cut down the http requests to 1 for our css files. I'm finding this size a CSS file a little unmanageable in light of the fact I'm performing updates on the site constantly. My concern is my users may catch me in the middle of updating and see a NON-styled page when moving from page to page - b/c 67kb still takes a good 2-3 seconds before it is successfully placed on the remote server via FTP. My question is: does the use of @import within this large CSS file to break up the files into smaller more manageable sizes (within that CSS file) take us back to the original 8 http-requests when the pages is loaded? Or are @imports in CSS handle differently somehow?

• Embed external website inside a page

  - by jasongullickson

  I'd like to load something from website B into a page on website A and contain the functionality of website B within a container on website A. I tried doing this using a div and jQuery's load() method but I run into cross-domain-scripting issues (I think, it works with a local file but not a remote URL). I also tried using an iframe but strange things happen (for example, when a link is clicked in the "contained" website B, it reloads the entire browser, losing the content of website A). I've read about some server-side ways of handling this (and it may just come to that) but ideally I want something completely client side, JavaScript and HTML. Any ideas?

• SVN Can't connect to host

  - by dan.codes

  We have a SVN repository setup on a remote host server. We have a brand new Dev server which eventually I will be setting up our repository on there, but for now I am trying to export a project onto the dev server from SVN. When I try to do it, I get svn: Can't connect to host 'website.com': Connection timed out. I can connect fine from any other server so I am assuming it must be something on the dev server, I am just not sure what setting might be blocking this. I can ping the server and that comes back with results, I thought maybe since it was a local network server, there might of been something blocking access to the external web. I'm just looking for a few ideas as to what it might be.

• Identify machine (relatively) uniquely using unc path

  - by Gareth

  Using C#, and given that the user enters in a unc path. Is there a way to verify that 2 months down the line, when I'm writing a file to the unc path, that it is the same machine as when he entered it? i.e. I'm writing some sensitive information to the path, and want to stop someone from putting another machine on the network with the same name / share etc and grabbing the output. Or if the software is running on a laptop and the user plugs it into another network, and there just happens to be a machine with the same name / share... Any ideas, other than using the IP address (and verifying that its the same?). I don't necessarily have any rights on the remote machine other than write access to the unc share. Yes, I'm probably being paranoid, but would like to know if anything is possible...

• Which language shouöd I take?

  - by Kovu

  Hi. I will build an application, that will be like a mix from a trojaner and a remote tool. It will be a spy programm for our company, so the IT Admin and Managment can see what the people are doing or not. (Only for explayning, please don't discuss about "uhhh tahts not ok"). I must choose a language for that. My best knowlegde is in C#.Net and VB.Net, but one main feature should be: No framework must be installed - so DotNet is out of the run. I decided to VB6 and a few minutes ago I ask for a IDE and some people say: Don't use it, it's too old. So, I must ask: What language do you prefer for such an project?

• Mercurial - How do you export your repo's source to a production site?

  - by orokusaki

  I've tried using archive in Tortoise HG by opening my repo change log. This doesn't seem to be anything like SVN's export command, where I can simply export a remote repository to the current directory. I use this to get a clean copy of my source for production (without notes and repository data). How can I do something like this in HG? Or, should I just use clone and deal with the repo related data manually? BTW, I need to do this all via command line since I'm not going to be using Tortoise HG on my Linux server. Any help is much appreciated.

• ColdFusion debugging output in my Ajax

  - by cf_PhillipSenn

  If I turn off "Enable Request Debugging Output", the 3rd option under the Debug Output Settings, then I no longer get debug info in my $.ajax call to a cfc with access="remote". That's good, but I'd like to keep it turned on for all my other programs and turn it off programatically for this one exception. I put <cfsetting showdebugoutput="false"> at the top of my Index.cfm, but that didn't turn off the debug output coming from the cfc. Oh wait. Never mind. I had to put the in the function rather than in Index.cfm.

• Access DB with SQL Server Front End

  - by uyuni99

  I have an old Access application that has a lot of code in forms and reports. The database is getting too large and I am thinking of moving the back end to SQL Server. My requirements are as follows: The DB needs to be multiuser and the users (3-5) will need to log in over the web I would prefer not to re-write the forms and reports in ASP or some other web front end. When I think about my choices, I see them as: Have an Access ADP front end and allows remote log-in to the server where it is stored. Not sure if it is possible for 2 users to simultaneously log in Distribute an ADP front end to the users, but I am not sure if it is possible to connect to a SQL Server back end over the internet, and the network traffic may be an issue. Any other solution? I appreciate all help. u
