• Active MQ showing more than one (ghost) consumer

  - by Shoey

  We have a system that uses ActiveMQ (Queues) - and have exactly one producer and one consumer (implemented as a Windows Service in .NET). Over the weekend, the infrastructure team had a reboot of the servers on the network, and from then on we noticed that there are more than one ghost consumer appearing that listens to the queue and we also suspect reads and deletes the messages. My questions are: is there any way from the Active MQ management console to find out what the consumers are (hostnames, etc). and Are there any scenarios in which inadvertent consumers get 'created'? For instance, there were suggestions about the active MQ journal folders getting corrupted after a reboot, or there is another suggestion that another machine with Active MQ broker automatically makes itself a consumer of all the queues on the main/live active mq server.

• Is there a script that can dynamically list the contents of a folder?

  - by user294756

  I am redesigning my company's intranet site in Wordpress and one of the things they need is an archive of company memos. There are over 300 memos saved in one location and I'm wondering if there is a jQuery script that I can run that will read the contents of a local (network) folder and auto-generate a list of the contents of that folder dynamically (and generate those names as a hyperlink to that file, but if I can list the files, I can get include the hyperlink tag myself). I can always manually create the list of hyperlinks (would take a couple days to do so) but if I can generate it dynamically, whenever a new memo is added, the script will automatically include it making the site much easier to maintain. Is this at all possible? I know that this can probably be done in PHP, but the page I need to do this on is not a php page, it is one of the subpages that is created in wordpress that does not have a php file extension and can't run php code (that I know of) Thanks in advance for any and all assistance.

• Deploying Rails app over VPN

  - by DavidGouge

  You'll have to bear with me as I'm not a Ruby dev, but have inherited a Ruby system. I need to deploy some changes to the app from my repository to the server. I've been instructed to run cap deploy and told that that script will get the latest code from my repository and deploy it to the server. My problem is that I have to VPN to get to the production server and the VPN client then blocks access to my local network, cutting off the repository. So my question is, how can I change my deploy.rb so that I can deploy from my local machine instead? Or is there a better way. If you need to see the deploy.rb, please let me know. Thanks Dave

• Forward a call to a webservice to another webservice?

  - by Luhmann

  If I have an https webservice behind a firewall on a machine (A) that I cannot access, but access to a machine on the same network (B), from where I can call the webservice on machine A. What is the best way of talking with the webservice on machine A, from the outside via machine B (that I access via VPN)? I can obviously create a service with a matching interface on machine B, and call the methods on the webservice on machine A, and return the result. But I fear for the overhead. Is there another way? Can i somehow forward the request?

• Point IIS at debug folder

  - by mtmurdock

  I am working on an asp.net mvc web service and an Android app that need to be able to communicate with one another. However, when running a web service/web site in Visual Studio it can only be accessed by that machine. So what I want to do is point IIS at my project's bin/debug folder, thus exposing my dev environment to my local network. I know this is possible because my work machine is set up this way, I just don't know how it is done. How do I configure IIS to load a web app from the debug directory of my Visual Studio project?

• HTML5 localStorage for assets (stylesheets, JavaScript, images etc)

  - by Sam

  To save both client download time and network usage, is it possible to use the localStorage feature of HTML5 to store contents of linked stylesheets, javascript files and binary data (e.g. images), rather than hitting the server each time? Would that just complicate things - since I assume you would have to add the linked asset via JavaScript rather than just a script or link element, breaking the page for those without JavaScript enabled)? Unless you can parse the content (using HEAD requested to check last modified date and other headers) before the browser downloads it. Or best just to stick with 304 Not Modified and eTag headers?

• Likelihood of IOError during print vs. write

  - by jkasnicki

  I recently encountered an IOError writing to a file on NFS. There wasn't a disk space or permission issue, so I assume this was just a network hiccup. The obvious solution is to wrap the write in a try-except, but I was curious whether the implementation of print and write in Python make either of the following more or less likely to raise IOError: f_print = open('print.txt', 'w') print >>f_print, 'test_print' f_print.close() vs. f_write = open('write.txt', 'w') f_write.write('test_write\n') f_write.close() (If it matters, specifically in Python 2.4 on Linux).

• continously add picture to video

  - by m.sr

  Every x minutes I grab an image from a network-cam. Now i want to add this picture to an existing video file - on the fly. I don't want to keep numerous image files and then encode them once in a while with e.g. mencoder mf://@${LIST} -mf type=jpg:fps=${FPS} ... The video format/codec doesn't really matter, as long as standard tools (mplayer, ffmpeg, vlc, ...) can handle it. Any ides or suggestions? Thanks in advance!

• I need guidance in building my first C# project

  - by grokker

  Hi I'm a PHP developer and I have some experience with Java. I'm trying to learn C# and my first project would be a program that starts the timer on a PC by clicking a button on another PC in the network. The problem is, I don't know where to start? What do I need to read up on? The OS for both PCs is Windows XP so they're desktop apps. I'd appreciate any help from you C# gurus. I hope my start as a C# programmer would be successful. Thank you!

• Communication between .net winform and webform

  - by Pablo

  Hi, I need to make a webform communicate with a winform and back to the webform. The reason for this is it exists a webform software already made, and now it's needed the behavior of a .net component only available for winforms. We've tried going with Process.Start and shell.execute but with this approach the software hangs or it takes too long to respond. The webform also needs to be called from client pcs in the network, I think this adds another problem due to the non possibility of calling the execution of a file from a webform remotelly, but I dont know much about this technical issue we've read some articles about embedding a winform in a webform, sending data from a winform to a webform, etc. and we would like to know what's the recommend approach (if there is any) for handdling a situation like this.

• Should we develop code on a local machine in a VLAN?

  - by red tiger

  Because of security reasons, we will not be able to use IIS on our local machines. I'm sure that many of you have faced the same problem, so how did you solve it? Here are the options that we're looking at: Create a VLAN that is isolated from the network for development. This will allow us to use any software, including IIS, that we want. A disadvantage is testing Web services with external organizations, which can be overcome by using stubs. Not use a VLAN and use only the ASP.NET Development Server that comes with Visual Studio, and then deploying that code to the development server. This has the disadvantage of not being able to replicate the production environment during local development. In addition, at least one developer needs IIS for GIS development, so he couldn't develop locally. Thank you for comments or suggestions that you may have!

• Sharing Eclipse directory on Dropbox between Windows and Mac OS X

  - by sowbug

  This question was close to mine, but not quite. I have a Windows desktop and a MacBook Pro. I'd like to be able to keep my Eclipse workspace in my Dropbox folder. The problem is that many project settings change between platforms: references to JREs, JDKs, and other libs. Every discussion I've seen of this problem seems to suggest taking advantage of the source control system's ignore functionality, so that such-and-such file remains local-only and thus able to remain platform-specific. But when you're working with a real single shared folder, that class of solution doesn't apply. Have you had luck working with a Java Eclipse project living in a single folder shared over the network, cross-platform?

• Java ServerSocketChannel SocketChannel (Callback)

  - by ikurtz

  I am trying to learn Java. I would like to implement a simple networked connect 4 game as well as a chat feature. I want my network logic to be non blocking so after much study I found that SocketChannel is what I am after regrading my needs. What has not made sense still is the lack of CallBack functions in SocketChannels.. Like one finds in C#. My query for this time is: How do I deliver the data received to the Chat or Game form (JFrame)? Some guidance is most welcome.

  i want to measure current download speed. im sending huge file over tcp. how can i capture the transfer rate every second? if i use IPv4InterfaceStatistics or similar method, instead of capturing the file transfer rate, i capture the device transfer rate. the problem with capturing device transfer rate is that it captures all ongoing data through the network device instead of the single file that i transfer. how can i capture the file transfer rate? im using c#.

• How can I convert (string) timestamp to mysql datetime on Windows 32 bit PHP?

  - by user239619

  I'm attempting to call LinkedIn's API and store Network Updates. Each update has a Unix timestamp that I'm retrieving as a string variable from the REST XML response. I want to convert the string timestamp to a mysql datetime format. The date() function accepts an integer as the second argument for time to be converted. However, I'm on Windows 32 bit PHP and the integer type for this platform is limited to 2147483647. $timestamp = '1293714626675'; // sample pulled from linkedin $timestamp = (int) $timestamp; // timestamp now equals 2147483647 $mysqlDatetime = date('Y-m-d H:i:s', $timestamp); // produces incorrect time Is there a better method of creating the mysql datetime in PHP? I realize that I can convert it upon insert into MySQL however, that would require changing other dependent code.

• PXE boot windows versions

  - by iJonathan

  I will make a PXE-server on Ubuntu for the installations of Windows XP and 7. When a computer starts from the network, then it should be display a menu with, for example "installation of XP" and the next item "installation of 7". When I select one of these items, the installation must start. I won't use an image, wds or FOG because the computers aren't the same and there a different departments in the company with a different configuration, programs etc. Neither Windows Server, only an Ubuntu PXE-server How I should start with making that? Thanks.

• Blackberry wifi connection issue

  - by AmitG

  Hi all, I have a very strange issue with my blackberry application. My application first searches for a blackberry network ( ;interface=wifi , ;deviceside=true , ;deviceside=false" + ";ConnectionUID="+ myRecord.getUid() ) transport and after finding one, it uses it to connect the server application. The issue is that some of my web services consumed by the bb client applicaton does not work when the connection type is wifi. Example: I have a series of web services called one after the other, login , x , y ,z, and logout. The connection transport selected = WIFI Login and LogOfff works fine but x, y and z web services return me an error message. The same series of web services ( Login, x,y,z, Log Out,) works with other connection transports ( eg. ap2trans) . Please help me with this issue as connecting to wifi ( if available ) is important for the application. Pleaes provide even the smallest info in this regad. thanks in advance

• How to turn off SSL on heroku

  - by rockyroadster555

  I'm redirecting a domain to Heroku using a cname. Currently Its working but is giving me an ssl error. Is there a way to turn off ssl on heroku? Heres the SSL Error This is probably not the site you are looking for! You attempted to reach app.grewpr.com, but instead you actually reached a server i identifying itself as *.herokuapp.com. This may be caused by a misconfiguration on the server or by something more serious. An attacker on your network could be trying to get you to visit a fake (and potentially harmful) version of app.grewpr.com. You should not proceed, especially if you have never seen this warning before for this site. When I try to go to http://pure-chamber-1979.herokuapp.com/ it automatically redirects me to the ssl version. Is there a way to turn this off?

• VSS Analyze - Access to file [filename] is denied

  - by AJ

  Our VSS database appears to be horribly out of shape. I've been trying to archive and run "analyze" and keep getting "Access to file [filename] is denied. The file may be read-only, may be in use, or you may not have permission to write to the file. Correct this problem and run analyze again." No one is logged into SourceSafe (including myself) and I'm running the analyze utility from the VS command prompt as follows: analyze -v -f -bbackuppath databasepath I get similar errors if I try and create project archives from the ssadmin tool. The database is on a network share, and we're running VSS 2005 v8.0.50727.42. I'd love to be able to do this, as it would be a first step in a move away from VSS. Thanks in advance. More Info Every time I run analyze, the file that spawns the access denied message changes. It's almost as if running analyze unlocks that file so that the next time I get through to the next one.

• 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.

• linked list problem (with insert)

  - by JohnWong

  The problem appears with the insert function that I wrote. 3 conditions must work, I tested b/w 1 and 2, b/w 2 and 3 and as last element, they worked. But b/w 3 and 4, it did not work. It only display up to the new added record, and did not show the fourth element. Efficiency is not my concern here (not yet). Please guide me through this debug process. Thank you very much. #include<iostream> #include<string> using namespace std; struct List // we create a structure called List { string name; string tele; List *nextAddr; }; void populate(List *); void display(List *); void insert(List *); int main() { const int MAXINPUT = 3; char ans; List * data, * current, * point; // create two pointers data = new List; current = data; for (int i = 0; i < (MAXINPUT - 1); i++) { populate(current); current->nextAddr = new List; current = current->nextAddr; } // last record we want to do it sepeartely populate(current); current->nextAddr = NULL; cout << "The current list consists of the following data records: " << endl; display(data); // now ask whether user wants to insert new record or not cout << "Do you want to add a new record (Y/N)?"; cin >> ans; if (ans == 'Y' || ans == 'y') { /* To insert b/w first and second, use point as parameter between second and third uses point->nextAddr between third and fourth uses point->nextAddr->nextAddr and insert as last element, uses current instead */ point = data; insert(()); display(data); } return 0; } void populate(List *data) { cout << "Enter a name: "; cin >> data->name; cout << "Enter a phone number: "; cin >> data->tele; return; } void display(List *content) { while (content != NULL) { cout << content->name << " " << content->tele; content = content->nextAddr; cout << endl; // we skip to next line } return; } void insert(List *last) { List * temp = last->nextAddr; //save the next address to temp last->nextAddr = new List; // now modify the address pointed to new allocation last = last->nextAddr; populate(last); last->nextAddr = temp; // now link all three together, eg 1-NEW-2 return; }

• Host unavailable when user is logged off

  - by aksamit

  I am facing a problem that I discovered while I was implementing a small client/host application. The client side runs Windows 7 64-bit and machine never turns off but user is automatically logged off after 30 minutes of inactivity. When user is automatically logged off the host becomes unreachable, first I thought the problem was isolated to my application, but after som investigation I discoverd that resources and vnc server is also unavailable. The question might be a bit off limit for this forum but I can't find any reasonable explanation somewhere else. Does anyone know how I can keep user being logged off automatically but with the host still reachable on the network?
