• Silence output from SimpleXMLRPCServer

  - by Corey Goldberg

  I am running an xml-rpc server using SimpleXMLRPCServer from the stdlib. My code looks something like this: import SimpleXMLRPCServer import socket class RemoteStarter: def start(self): return 'foo' rs = RemoteStarter() host = socket.gethostbyaddr(socket.gethostname())[0] port = 9000 server = SimpleXMLRPCServer.SimpleXMLRPCServer((host, port)) server.register_instance(rs) server.serve_forever() every time the 'start' method gets called remotely, the server prints an access line like this: <server_name> - - [10/Mar/2010 13:06:20] "POST /RPC2 HTTP/1.0" 200 - I can't figure out a way to silence the output so it doesn't print these access lines to stdout. anyone?

• Ruby: writing a network redirector

  - by Shyam

  Hi, I would like to research protocols such as HTTP. As I am learning Ruby, I would like to write a program that works as a "gateway". I would be connecting to it's port on for example 8080 and the program should forward my request to the real host and send back the answers. The idea of my design is something like this: class EchoProxy def run # run a listening socket on port 8080 myinfiniteloop end def myinfiniteloop # continually run this loop unless the app is terminated puts traffic end end Some pointers in the right direction would be great! Thank you for your comments, answers and feedback!

• Errors when connecting to HTTPS using HTTP::Net routines (Ruby on Rails)

  - by jaycode

  Hi all, the code below explains the problem in detail #this returns error Net::HTTPBadResponse url = URI.parse('https://sitename.com') response = Net::HTTP.start(url.host, url.port) {|http| http.get('/remote/register_device') } #this works url = URI.parse('http://sitename.com') response = Net::HTTP.start(url.host, url.port) {|http| http.get('/remote/register_device') } #this returns error Net::HTTPBadResponse response = Net::HTTP.post_form(URI.parse('https://sitename.com/remote/register_device'), {:text => 'hello world'}) #this returns error Errno::ECONNRESET (Connection reset by peer) response = Net::HTTP.post_form(URI.parse('https://sandbox.itunes.apple.com/verifyReceipt'), {:text => 'hello world'}) #this works response = Net::HTTP.post_form(URI.parse('http://sitename.com/remote/register_device'), {:text => 'hello world'}) So... how do I send POST parameters to https://sitename.com or https://sandbox.itunes.apple.com/verifyReceipt in this example?

• Django: tinyMCE and cross site javascript

  - by pistacchio

  Hi, follow this question, I was able to set some textareas in my admin page as richtext inputs. The most voted answer suggests to follow an example and is what i did. Also, it talks about a problem concerning "blank pages". I'm having the same problem and I'm not able to solve it. I have my media files served by a different server, so MEDIA_URL points to a different host with a different port. To simulate this in my dev environment, I also serve media files from a different port. Debugging the failing javascript, Chrome yelds: Unsafe JavaScript attempt to access frame with URL http://localhost:8000/admin/blog/post/add/ from frame with URL http://localhost:88/s3mangerie/js/tiny_mce/themes/advanced/image.htm. Domains, protocols and ports must match. How to solve this problem? Thanks

• How to install Nokogiri as a Macruby gem?

  - by Jakub Hampl

  The latest MacRuby release notes (v0.6) state that the authors have managed to get this release working with the SQLite and Nokogiri gems. However when I run sudo macgem install nokogiri I get the following errors: ERROR: Error installing nokogiri: extconf failed: and then a bunch of paths followed by: libxml2 is missing. try 'port install libxml2' or 'yum install libxml2' /Library/Frameworks/MacRuby.framework/Versions/0.6/usr/lib/ruby/Gems/1.9.0/gems/nokogiri-1.4.1/ext/nokogiri/extconf.rb:1:in `<main>': libxml2 is missing. try 'port install libxml2' or 'yum install libxml2' (SystemExit) Anyone knows how to get this working? My platform is Mac OS X 10.6.3. Nokogiri normally (meaining on plain old ruby 1.8.7) installs without a problem.

• GDB skips over my code!

  - by sheepsimulator

  So, I've defined a class like DataLoggingSystemStateReceiver { DataLoggingSystemStateReceiver() { // stuff } // ... other functions here }; In main, I instantiate DataLoggingSystemStateReceiver like so: int main() { // ... run stuff Sensor sensor(port, timer); DataLoggingSystemStateReceiver dlss(); Log::notice("started"); return 0; } However, when I step through this code in gdb, it runs: Sensor sensor(port, timer); skips DataLoggingSystemStateReceiver dlss(); and continues with Log::notice("started"); What gives? EDIT: By changing DataLoggingSystemStateReceiver dlss(); to DataLoggingSystemStateReceiver dlss; in main(), the line executes. Can someone explain why?

• Encoding multiple video streams with a single avconv invocation

  - by automatthias

  I played with avconv on Ubuntu and I'm now able to e.g. record the desktop with sound from a soundcard. One thing I wanted to do was recording two video inputs at the same time, for instance the desktop and from the webcam. I thought about doing something like this: avconv \ -f alsa \ -i default \ -acodec flac \ -f video4linux2 \ -r 6 \ -i /dev/video0 \ -f x11grab \ -i :0.0 \ out.mkv My thinking was that if you define multiple video inputs, and the .mkv format can handle multiple video streams, avconv will encode 2 video streams and 1 audio stream into one file. But this isn't what happens: avconv version 0.8.4-6:0.8.4-0ubuntu0.12.10.1, Copyright (c) 2000-2012 the Libav developers built on Nov 6 2012 16:51:11 with gcc 4.7.2 [alsa @ 0x1091bc0] capture with some ALSA plugins, especially dsnoop, may hang.

I'm not sure if it's the question of mapping (some -map options to add?) or that avconv just can't encode more than 1 video stream at one time. So is it an actual avconv limitation, or a limitation of the available containers, or me simply not finding the right combination of command line options?

• How have popular iPhone games been ported to Android?

  - by Cirrostratus

  I am not asking how could they have been, I want to know the real answer. Doodle Jump, Paper Toss and some others have versions on the iPhone and Android that are nearly exactly the same, with the iPhone version coming first. There is a small Objective-C compiler project for Android's NDK but the timing isn't right for these apps. There's also an Android port of Cocos2d but I doubt Doodle Jump used that. Titanium? Doubtful. As their respective code bases grow, I figure it'd get harder and harder to do an exact port from Objective-C to Java every release so I wonder if there is a better way. Are they sharing C++ code for example?

• Limit Connections with semaphores

  - by Robert

  I'm trying to limit the number of connections my server will accept using semaphores, but when running, my code doesn't seem to make this restriction - am I using the semaphore correctly? eg. I have hardcoded the number of permit as 2, but I can connect an unlimited number of clients... public class EServer implements Runnable { private ServerSocket serverSocket; private int numberofConnections = 0; private Semaphore sem = new Semaphore(2); private volatile boolean keepProcessing = true; public EServer(int port) throws IOException { serverSocket = new ServerSocket(port); } @Override public void run() { while (keepProcessing) { try { sem.acquire(); Socket socket = serverSocket.accept(); process(socket, getNextConnectionNumber()); } catch (Exception e) { } finally { sem.release(); } } closeIgnoringException(serverSocket); } private synchronized int getNextConnectionNumber() { return ++numberofConnections; } // processing related methods }

• ImageMagick on Mac OSX Snow Leopard. Is there any way to get it to compile and run?

  - by ?????

  It seems that I have more trouble getting standard Unix things to run on Snow Leopard than any other platform--including Windows cygwin For the past couple of days, I've been trying to get ImageMagick to run on Snow Leopard. The most obvious way, Mac Ports, fails: tppllc-Mac-Pro:ImageMagick-sl swirsky$ sudo port install imagemagick ---> Computing dependencies for p5-locale-gettext ---> Configuring p5-locale-gettext Error: Target org.macports.configure returned: configure failure: shell command " cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_perl_p5-locale-gettext/work/gettext-1.05" && /opt/local/bin/perl Makefile.PL INSTALLDIRS=vendor " returned error 2 Command output: checking for gettext... no checking for gettext in -I/opt/local/include -arch i386 -L/opt/local/lib -lintl...gettext function not found.

So now I'm two steps away from ImageMagick, trying to get a newer libiconv on my machine. I downloaded the latest libiconv, compiled and built it. I put the resulting library in /opt/local/lib, and I still get the same error message: tppllc-Mac-Pro:.libs swirsky$ sudo mv libiconv.2.dylib /opt/local/lib/libiconv.2.dylib tppllc-Mac-Pro:.libs swirsky$ convert dyld: Library not loaded: /opt/local/lib/libiconv.2.dylib Referenced from: /opt/local/lib/libfontconfig.1.dylib Reason: Incompatible library version: libfontconfig.1.dylib requires version 8.0.0 or later, but libiconv.2.dylib provides version 7.0.0 Trace/BPT trap Now here's something interesting. The error message shows it's looking in /opt/local/lib/libiconv.2.dylib. otools -L shows that this does implement 8.0.0: tppllc-Mac-Pro:.libs swirsky$ otool -L /opt/local/lib/libiconv.2.dylib /opt/local/lib/libiconv.2.dylib: /usr/local/lib/libiconv.2.dylib (compatibility version 8.0.0, current version 8.0.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 125.0.0) tppllc-Mac-Pro:.libs swirsky$ And, for good measure, I set the DYLD_LIBRARY_PATH to make sure this directory is the one for dynamic libraries. So even though I do have a library that provides 8.0.0, it's being seen as 7.0.0! Any ideas why this would happen? So here's my question: Is it possible to get ImageMagick to run on OSX Snow Leopard? Are there any binary distributions that have static libraries baked in so I don't have to worry about these issue/

• Stuck on an ASP.NET/WCF WSDL Parsing Error

  - by Vaccano

  I have a WCF Web Service that my ASP.NET app uses. It has been working fine for quite some time. I just added in a Dev Express Grid (and the Dev Express DLLs) and a new page that uses them and now I am getting parsing errors on the WSDL. But the weird part is that it works fine on my machine but fails on the web server machine. (Both are connecting to the same web services WSDL.) Here is the error message I am getting: Server Error in '/MyWebAppWebDev' Application. -------------------------------------------------------------------------------- Parser Error Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.

• Proxy calls across a DMZ

  - by John

  We need to determine a quick way for our web application deployed in a DMZ to communicate to our SQL server that lives in the protected network. Only port 80 is open and available, and no direct SQL traffic is allowed across the firewall. So take the following simple system. A web page (default.aspx) makes a call (string GetData()) that resides in an assembly (Simple.DLL). GetData() uses ADO.NET to open a connection, execute a SQL call, retrieve the data, and return the data to the caller. However, since only port 80 is available and no SQL traffic is allowed, what could we do to accomplish our goal? I believe a .NET remoting solution would work, and I have heard of an architecture where a remoting layer proxies the call from Simple.DLL in the DMZ to another Simple.DLL that runs on the protected side. The remoting layer handles the communication between the two DLL’s. Can someone shed some light on how WCF/remoting can help us and how to get started with a solution?

• Problem with starting OpenOffice service (soffice) from Java (command working in commandline, but no

  I want to exceute a simple command which works from the shell but doesn't work from Java. This is the command I want to execute, which works fine: soffice -headless "-accept=socket,host=localhost,port=8100;urp;" This is the code I am excecuting from Java trying to run this command: String[] commands = new String[] {"soffice","-headless","\"-accept=socket,host=localhost,port=8100;urp;\""}; Process process = Runtime.getRuntime().exec(commands) int code = process.waitFor(); if(code == 0) System.out.println("Commands executed successfully"); When I run this program I get "Commands executed successfully". However the process is not running when the program finishes. Is it possible that the JVM kills the program after it has run? Why doesn't this work?

• SSH Password/User problem with Cygwin sshd service

  hello I just set up SSHd through Cygwin on a Windows XP Pro box overseas using a RAT and discluded the openssh package from the install. I ran the cywin shell (from c:\cywin) and ran Now, It's under a port I know is safe and fowarded properly, but I won't share it's number. It's not a common port, but it's under 40000. Firewalls are off etc etc. I'm on the first Admin account made on the box. (It's full admin) I've run the following commands chmod +r /etc/passwd chmod +r /etc/group hmod 777 /var /*Created New Admin User Account To Be Used via SSH*/ mkpasswd -cl > /etc/passwd mkgroup --local > /etc/group I can connect locally, but not externally. I know my ports etc are fine. Any possible problems, as i really need this tunnel up :P

Is there another version of emacs for windows that just works!

• About Network Address Translation (NAT)?

  - by Rudi

  Just curious about a particular scenario of NAT. Let's suppose we have 4 computers sharing a global IP address under the NAT. I understand that the NAT box keeps an internal record to know which computer to forward requests to. But let's say on computer #2 I'm trying to download a file. And let's say on computer #1, #3, and #4, I'm just browsing the web normally. When the browser initiates a TCP connection to get that file, how does it know which computer to give it to? I mean like, each of the four computers is using port 80 to browse the web right? How does the NAT's record distinguish which "port 80" belongs to which computer?

• How can I write a file on an ftps-server with PHP?

  - by Daniel

  Hi, I hope someone here could help me, because I couldn't find any solution with Google. What I have to do is to generate a XML-string (that works) an save that directly into a file on an ftps-server. So far, so good... I used the following code with ftp and it works to, but not with ftps. So I either need another options-configuration for the stream or a different way to solve that task. Here my current code: $host = 'ftp.example.com'; $port = 22; $user = 'xxxxxx'; $pass = 'xxxxxx'; $file = 'test_' . time() . '.txt'; $ftpPath = sprintf('ftp://%s:%s@%s:%d/%s', $user, $pass, $host, $port, $file); $context = stream_context_create(array('ftp' = array('overwrite' = true))); file_put_contents($ftpPath, 'test', 0, $context);

• get length of data sent over network to TCPlistener/networkstream vb.net

  - by Jonathan.

  It seems the most obvious thing, but I just can't work out how to get the length of bytes sent over a network using a TCPClient and TCPListener? This is my code so far: 'Must listen on correct port- must be same as port client wants to connect on. Const portNumber As Integer = 9999 Dim tcpListener As New TcpListener(IPAddress.Parse("192.168.2.7"), portNumber) tcpListener.Start() Console.WriteLine("Waiting for connection...") 'Accept the pending client connection and return 'a TcpClient initialized for communication. Dim tcpClient As TcpClient = tcpListener.AcceptTcpClient() Console.WriteLine("Connection accepted.") ' Get the stream Dim networkStream As NetworkStream = tcpClient.GetStream() '' Read the stream into a byte array I need to get the length of the networkstream to set the size of the array of bytes I'm going to read the data into. But the networkStream.length is unsupported and does not work and throws an Notsupportedexception. The only other way I can think of is to send the size of the data before sending the data, but this seems the long way round.

If I write the following: Pony.mail( :to => message[:to], :from => @account[:from], :subject => message[:subject], :content_type => 'text/html', :html_body => "<h1>hey there!</h1>", :via => :smtp, :smtp => { :host => MY_HOST, :port => PORT, :auth => AUTH, :user => MY_USER, :password => MY_PASSWORD, :tls => true } ) The code above send a mail but the message appears to be empty in gmail. Any help would be greatly appreciated on this. Thanks.
