  • How to simulate a dial-up connection for testing purposes?

    - by mawg
    I have to code a server app where clients open a TCP/IP socket, send some data and close the connection. The data packets are small < 100 bytes, however there is talk of having them batch their transactions and send multiple packets. How can I best simulate a dial-up ut connection (using Delphy & Indy components, just FYI)? Is it as simple as open connection wait a while (what is the definition of "a while"?) close connection

  • Where can I find a good definition of a Software construct?

    - by Hugh
    I have scoured for 2 hours now across the internet, I have found courses with modules on software constructs but no clear definition only hints as to what one is. As far as I understand the definition it is an object that can be defined with a purpose for example a TCP/IP connection uses a Port which is a Software construct. Can anyone refer me to a full definition or give a more robust one?

  • State server in webfarm scenario?

    - by Curtis White
    This is a fairly basic question about state server but assume there are 2 servers behind a load balancer. How do I configure the session state server? So, I have machine1 and machine2. I would assume that I would need to install the state server on 1 machine only and then use the internal IP to refer to that machine. Is this correct? As oppose too, I would not install state server on both machines.

  • Using WAMP's MySQL with Cygwin Ruby on Rails

    - by Andrei
    I'm trying to install a Rails app on a Cygwin Rails + WAMP MySQL setup, but rake trows an error : Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2) Of course, it's trying to connect to MySQL trought a Cygwin socket, and since there's no MySQL server running on Cygwin, it fails. How do I get Rails to connect to WAMP's MySQL (perhaps through TCP/IP instead of a socket) ?

  • XML - how to use namespace prefixes

    - by Asbie
    I have this XML at http://localhost/file.xml: <?xml version="1.0" encoding="utf-8"?> <val:Root xmlns:val="http://www.hw-group.com/XMLSchema/ste/values.xsd"> <Agent> <Version>2.0.3</Version> <XmlVer>1.01</XmlVer> <DeviceName>HWg-STE</DeviceName> <Model>33</Model> <vendor_id>0</vendor_id> <MAC>00:0A:DA:01:DA:DA</MAC> <IP>192.168.1.1</IP> <MASK>255.255.255.0</MASK> <sys_name>HWg-STE</sys_name> <sys_location/> <sys_contact> HWg-STE:For more information try http://www.hw-group.com </sys_contact> </Agent> <SenSet> <Entry> <ID>215</ID> <Name>Home</Name> <Units>C</Units> <Value>27.7</Value> <Min>10.0</Min> <Max>40.0</Max> <Hyst>0.0</Hyst> <EmailSMS>1</EmailSMS> <State>1</State> </Entry> </SenSet> </val:Root> I am trying to read this from my c# code: static void Main(string[] args) { var xmlDoc = new XmlDocument(); xmlDoc.Load("http://localhost/file.xml"); XmlElement root = xmlDoc.DocumentElement; // Create an XmlNamespaceManager to resolve the default namespace. XmlNamespaceManager nsmgr = new XmlNamespaceManager(xmlDoc.NameTable); nsmgr.AddNamespace("val", "http://www.hw-group.com/XMLSchema/ste/values.xsd"); XmlNodeList nodes = root.SelectNodes("/val:SenSet/val:Entry"); foreach (XmlNode node in nodes) { string name = node["Name"].InnerText; string value = node["Value"].InnerText; Console.Write("name\t{0}\value\t{1}", name, value); } Console.ReadKey(); } } Problem is that the node is empty. I understand this is a common newbie problem when reading XML, still not able to solve what I am doing wrong, probably something with the Namespace "val" ?

  • Getting a visitors Facebook page

    - by Mr Carl
    Hey guys, this is more of a question out of curiosity, but is it possible to get somebody's Facebook page after they have visited your site? Was thinking maybe a chain of lookup stuff could be used starting with an IP to eventually perhaps get a name and thus that person's Facebook page. I have also heard you can read somebody's web history, is this true?

  • closing MQ connection

    - by OakvilleWork
    Good afternoon, I wrote a project to Get Park Queue Info from the IBM MQ, it has producing an error when attempting to close the connection though. It is written in java. Under application in Event Viewer on the MQ machine it displays two errors. They are: “Channel program ended abnormally. Channel program ‘system.def.surconn’ ended abnormally. Look at previous error messages for channel program ‘system.def.surconn’ in the error files to determine the cause of the failure. The other message states: “Error on receive from host rnanaj (10.10.12.34) An error occurred receiving data from rnanaj (10.10.12.34) over tcp/ip. This may be due to a communications failure. The return code from tcp/ip recv() call was 10054 (X’2746’). Record these values.” This must be something how I try to connect or close the connection, below I have my code to connect and close, any ideas?? Connect: _logger.info("Start"); File outputFile = new File(System.getProperty("PROJECT_HOME"), "run/" + this.getClass().getSimpleName() + "." + System.getProperty("qmgr") + ".txt"); FileUtils.mkdirs(outputFile.getParentFile()); Connection jmsConn = null; Session jmsSession = null; QueueBrowser queueBrowser = null; BufferedWriter commandsBw = null; try { // get queue connection MQConnectionFactory MQConn = new MQConnectionFactory(); MQConn.setHostName(System.getProperty("host")); MQConn.setPort(Integer.valueOf(System.getProperty("port"))); MQConn.setQueueManager(System.getProperty("qmgr")); MQConn.setChannel("SYSTEM.DEF.SVRCONN"); MQConn.setTransportType(JMSC.MQJMS_TP_CLIENT_MQ_TCPIP); jmsConn = (Connection) MQConn.createConnection(); jmsSession = jmsConn.createSession(false, Session.AUTO_ACKNOWLEDGE); Queue jmsQueue = jmsSession.createQueue("PARK"); // browse thru messages queueBrowser = jmsSession.createBrowser(jmsQueue); Enumeration msgEnum = queueBrowser.getEnumeration(); commandsBw = new BufferedWriter(new FileWriter(outputFile)); // String line = "DateTime\tMsgID\tOrigMsgID\tCorrelationID\tComputerName\tSubsystem\tDispatcherName\tProcessor\tJobID\tErrorMsg"; commandsBw.write(line); commandsBw.newLine(); while (msgEnum.hasMoreElements()) { Message message = (Message) msgEnum.nextElement(); line = dateFormatter.format(new Date(message.getJMSTimestamp())) + "\t" + message.getJMSMessageID() + "\t" + message.getStringProperty("pkd_orig_jms_msg_id") + "\t" + message.getJMSCorrelationID() + "\t" + message.getStringProperty("pkd_computer_name") + "\t" + message.getStringProperty("pkd_subsystem") + "\t" + message.getStringProperty("pkd_dispatcher_name") + "\t" + message.getStringProperty("pkd_processor") + "\t" + message.getStringProperty("pkd_job_id") + "\t" + message.getStringProperty("pkd_sysex_msg"); _logger.info(line); commandsBw.write(line); commandsBw.newLine(); } } Close: finally { IO.close(commandsBw); if (queueBrowser != null) { try { queueBrowser.close();} catch (Exception ignore) {}} if (jmsSession != null) { try { jmsSession.close();} catch (Exception ignore) {}} if (jmsConn != null) { try { jmsConn.stop();} catch (Exception ignore) {}} }

  • .net: does anyone know a free library to download nntp messages

    - by stighy
    hi folks, i'm using ip*works for download newsgroup message and insert them into a database... ipworks is "comfortable" to use because it automatically split nntp data return into different object (or variable). So i've "author" "date" "topic" "messagge" already splitted to my use. However ipworks isn't free and it cost a lot for my use.. so i'm asking you some component or code snippet to use to download and "manage" nntp messagges. Thanks in advance and regards!

    I have a function in powershell 2.0 named getip which gets the IP address(es) of a remote system. function getip { $strComputer = "computername" $colItems = GWMI -cl "Win32_NetworkAdapterConfiguration" -name "root\CimV2" -comp $strComputer -filter "IpEnabled = TRUE" ForEach ($objItem in $colItems) {Write-Host $objItem.IpAddress} } The problem I'm having is with getting the output of this function to a variable. The folowing doesn't work... $ipaddress = (getip) $ipaddress = getip set-variable -name ipaddress -value (getip) any help with this problem would be greatly appreciated.

  • Redirect to a web server depending on location with nginx

    - by fceruti
    Im working on a web site that has to be reachable from many countries under the same domain. Id like to know how can I receive a request with nginx (or any other static file server), and send it to different web servers depending on IP's location. I mean, what is the point on having multiple db machines on country A and B, if the server that serves you the page is chosen by round robin. Maybe theres another solution to my problem, and I would be very happy if someone can explain it to me.

    - by Ethan
    Sample code: $html = file_get_contents('http://www.google.com'); echo $html; It works on localhost. But after uploading to the webserver, it gives me a warning: file_get_contents(): php_network_getaddresses: getaddrinfo failed: Temporary failure in name resolution. If I replace the domain name with google's IP address, it gives a warning: failed to open stream: Connection timed out. And ini_get("allow_url_fopen") return 1.

    - by klork
    We have a Business Listings directory hosted on IIS 6 Windows 2003. Our competitors crawl and steal our content and customers. We have tried IP blocking using honeypot URLs and log parsing without much success. Is anyone aware of a network device or a proxy server that I can run in front of my web server to minimize this issue? All suggestions are highly appreciated.

  • Cannot Call WordPress Plugin Files Under wp-content

    - by Volomike
    I have a client who has many blog customers. Each of these WordPress blogs calls a plugin that provides a product link. The way that link is composed looks like this: {website}/wp-content/plugins/prodx/product?id=432320 This works fine on all blogs except two. On those two, when you try to call the URL, you get a 404. So, I disabled all plugins except prodx and reverted the theme to default (Kubrick), thinking perhaps a plugin intercept with add_action() API was doing this, such as intercepting URLs and redirecting them. However, this did not help. So, I upgraded the WordPress to the latest version. Again, didn't fix. So, I checked permissions, comparing with a blog that worked just fine. Again, didn't fix. So I replaced the .htaccess, using one from a working blog. Again, didn't fix. So I replaced all the files using some from a working blog that was identical to this one, and then restored the wp-config.php file back so that it talked to the right blog database. Again, didn't fix. Again I checked permissions meticulously, comparing to a perfectly working blog. Again, didn't fix. So, I created a test.php that looks like so: <?php print_r($_GET); echo "hello world"; I then copied it into another plugin folder and used my browser to get to it -- again, 404. So I copied it into the root of wp-content/plugins and tried to call it there -- again, 404. So I copied it into wp-content -- again, 404. Last, I copied it into the root of the WordPress blog website, and this time, it worked! Doesn't make sense. I started to think that perhaps something was going on with /etc/httpd/conf/httpd.conf for this customer, but the only thing I saw different in their for this customer was the IP address was different than the customer's blog that worked. Each customer gets their own IP in this environment my client has built. My client sysop is baffled too. What do you think is going on? Is there something wrong in the WP database for this customer? Is there something wrong in httpd.conf?
