  • how to change document root to public_html from root directory

    - by manish
    For testing I hosted my website on free server from 000webhost.com They have a directory structure:- (root folder) \ (public folder) \public_html this directory structure enables to keep all the library files in root folder and all public data in \public_html, so I developed my website accordingly, and my final structure looked like:- / /include(this folder contains library files) /logs(log files) /public_html /public_html/index.php /public_html/home.php /public_html/and other public files on 000webhost makes only public_folder available to be accessed via url and my url looked neat and clean like www.xample.com/index.php or www.example.com/home.php but after completion of development I moved website to shared host purchased from go-daddy.com, now they do not have any such kind of directory permission, all the files are kept in root folder and are accessible via url also url has become like:- www.example.com/public_html/home.php or www.example.com/public_html/index.php How should I redirect url request to public_html folder again so as to make library file unavailable to public access and make url neat and clean.

  • The current state of a MERGE Destination for SSIS

    - by jamiet
    Hugo Tap asked me on Twitter earlier today whether or not there existed a SSIS Dataflow Destination component that enabled one to MERGE data into a table rather than INSERT it. Its a common request so I thought it might be useful to summarise the current state of play as regards a MERGE destination for SSIS. Firstly, there is no MERGE destination component in the box; that is, when you install SSIS no MERGE Destination will be available. That being said the SSIS team have made available a MERGE destination component via Codeplex which you can get from http://sqlsrvintegrationsrv.codeplex.com/releases/view/19048. I have never used it so cannot vouch for its usefulness although judging by some of the reviews you might not want to set your expectations too high. Your mileage may vary.   In the past it has occurred to me that a built-in way to provide MERGE from the SSIS pipeline would be highly valuable. I assume that this would have to be provided by the database into which you were merging hence in March 2010 I submitted the following two requests to Connect: BULK MERGE (111 votes at the time of writing) [SSIS] BULK MERGE Destination (15 votes) If you think these would be useful feel free to vote them up and add a comment. Lastly, this one is nothing to do with SSIS but if you want to perform a minimally logged MERGE using T-SQL Sunil Agarwal has explained how at Minimal logging and MERGE statement. @Jamiet

  • What should every programmer know about web development?

    - by Joel Coehoorn
    What things should a programmer implementing the technical details of a web application before making the site public? If Jeff Atwood can forget about HttpOnly cookies, sitemaps, and cross-site request forgeries all in the same site, what important thing could I be forgetting as well? I'm thinking about this from a web developer's perspective, such that someone else is creating the actual design and content for the site. So while usability and content may be more important than the platform, you the programmer have little say in that. What you do need to worry about is that your implementation of the platform is stable, performs well, is secure, and meets any other business goals (like not cost too much, take too long to build, and rank as well with Google as the content supports). Think of this from the perspective of a developer who's done some work for intranet-type applications in a fairly trusted environment, and is about to have his first shot and putting out a potentially popular site for the entire big bad world wide web. Also, I'm looking for something more specific than just a vague "web standards" response. I mean, HTML, JavaScript, and CSS over HTTP are pretty much a given, especially when I've already specified that you're a professional web developer. So going beyond that, Which standards? In what circumstances, and why? Provide a link to the standard's specification.

  • WARNING Retrying Bulk Insert for file:sqlldr due to Communication Error:256

    - by user702295
    WARNING Retrying Bulk Insert for file:sqlldr due to Communication Error:256 I am running my engine on Linux and am receiving an intermittent message "WARNING Retrying bulk insert for file: sqlldr due to communication Error: 256" The engine seems to have completed successfully, but it is not clear if this error caused some of the forecast to not complete. It is also not clear what caused the error. Generally if you see only the WARNING of it, it means that next retries of the same load request have eventually succeeded and so the run a a whole is not affected. In order to know more about what happens, look for .log/.bad files left in the engines bin directory or possibly a quote of them within the specific engine log that had the issue.  The sqlnet.log file may also have some information about it and perhaps at the database server side there may be some log/alert regarding what happened.  Look at the alert.log. In general it could be that the database server/network was over loaded at the time and somehow the connection was rejected/failed/aborted either due to specific setting on concurrent connections/sessions or inadvertently due to glitch in network/os/hardware. If this repeats and becomes more frequent during the run you should look further into it as mentioned above. You can also track this using either SQL*Trace or java.util.logging.  - Globally enable logging by setting the oracle.jdbc.Trace system property java -Doracle.jdbc.Trace=true - Client Side Tracing: Your SQLNET.ORA file should contain the following lines to produce a client side trace file: trace_level_client = 10 trace_unique_client = on trace_file_client = sqlnet.trc trace_directory_client = <path_to_trace_dir> Server Side Tracing: To enable server side tracing, use the following parameters: trace_level_server = 10 trace_file_server = server.trc trace_directory_server = <path_to_trace_dir> Tracing Levels: The following values can be used for TRACE_LEVEL* parameters:     16 or SUPPORT — WorldWide Customer Support trace information     10 or ADMIN — Administration trace information     4 or USER — User trace information     0 or OFF — no tracing, the default Additional information is readily available via the web.

  • Adsense-type services without the content check?

    - by Ryan Ahearn
    Are there any ad-placing services that don't mind that the page is nothing but a page of ads? Someone else with a .cn tld is pointing to my IP address. I currently have that site on its own name based virtual host that responds to every request with a 403, but I figure if I am paying for the incoming bandwidth, I might as well try to make some money off it. I don't want to actually create any content for this site, which prevents me from using adsense. My only requirements are that it is free for me to sign up and that they don't mind the lack of content.

  • Apache RewriteRule with a RewriteMap variable substitution for the VAL argument to environment variable

    - by Eric
    I have an Apache server that serves up binary files to an application (not a browser). The application making the request wants the HTTP Content-MD5 header in HEX format. The default and only option within Apache is Base64. If I add "ContentDigest on" to my VirtualHost, I get this header in Base64. So I wrote a perl script, md5digesthex.pl, that gives me exactly what I want: MD5 in HEX format but I'm struggling with the RewriteRule to get my server to send the result. Here is my current Rewrite recipe: RewriteEngine on RewriteMap md5inhex prg:/www/download/md5digesthex.pl RewriteCond %{REQUEST_URI} ^/download/(.*) RewriteRule ^(.*) %{REQUEST_URI} [E=HASH:${md5inhex:$1}] Header set Content-MD5 "%{HASH}e" env=HASH The problem is that I can't seem to set the HASH environment variable based on the output of the md5inhex map function. It appears this behavior is not supported and I'm at a lost as to how to formulate this...

  • Clients with multiple proxy and multithreading callbacks

    - by enzom83
    I created a sessionful web service using WCF, and in particular I used the NetTcpBinding binding. In addition to methods to initiate and terminate a session, other methods allow the client to send to one or more tasks to be performed (the results are returned via callback, so the service is duplex), but they also allow you to know the status of the service. Assuming you activate the same service on multiple endpoints, and assuming that the client knows these endpoints (for example, it could maintain a List of endpoints), the client should connect with one or more replicas of the same service. The client periodically updates the status of the service, so when it needs to perform a new task (the task is submitted by the user via UI), it selects the service currently less loaded and sends the task to it. Periodically, the client also initiates a maintenance procedure in order to disconnect from one or more overloaded service and in order to connect with new services. I created a client proxy using the svcutil tool. I wish each proxy can be used simultaneously by different threads, for example, in addition to the thread that submits the tasks using a proxy, there are also the following two threads which act periodically: a thread that periodically sends a request to the service in order to obtain the updated state; a thread that periodically selects a proxy to close and instantiates a new proxy to replace the closed one. To achieve these objectives, is it sufficient to create an array of proxies and manage their opening and closing in separate threads? I think I read that the proxy method calls are thread safe, so I would not need to perform a lock before requesting updates to the service. However, when the maintenance procedure (which is activated on its own thread) decides to close a proxy, should I perform a lock? Finally, each proxy is also associated with an object that implements the callback interface for the service: are the callbacks (invoked on the client) executed on different threads on the client? I would like to wrap the management of the proxy in one or more classes so that it can then easily manage within a WPF application.

  • Configure IIS 7 Reverse Proxy to connect to TeamCity Tomcat

    - by Cynicszm
    We have an IIS 7 webserver configured and would like to create a reverse proxy for a TeamCity installation using Tomcat on the same machine. The IIS server site is https://somesite and I would like the TeamCity to appear as https://somesite/teamcity redirecting to http://localhost:portnumber I have installed the IIS URL Rewrite extension from http://www.iis.net/download/URLRewrite and the Application Request Routing from http://www.iis.net/download/ApplicationRequestRouting to try and setup a reverse proxy but can't get it working. The closest answer I found is an old StackOverflow question http://stackoverflow.com/questions/331755/how-do-i-setup-teamcity-for-public-access-over-https which unfortunately doesn't have a working example. I've searched a quite a bit but can't seem to find a relevant example. Any help appreciated (apologies for the bold but the spam prevention won't let me post more than 1 hyperlink)

  • How To Perform Distributed Website Monitoring?

    - by cballou
    I would like to know how sites like the following perform distributed website monitoring (from multiple checkpoints/countries). pingdom.com, site24x7.com, uptrends.com, siteuptime.com, etc, etc. To be exact, what process would occur in checking if a given domain name went down? If the server finds that the site is down, what is the next step? Would it make a REST API request to a separate server to run the same test and report the results? I have a few theories, including: utilizing host(s) from different countries utilizing proxies from different countries I'm looking for the most proper or correct way to handle this, which can include the usage of servers from multiple countries/hosts.

  • NodeJS Supervisord Hashlib

    - by enedebe
    I have an problem with my NodeJS app. The problem is the include of the library Hashlib I've followed more than 10 times the instructions to install. Get a clone of the repo, do make and make install. NodeJS is installed in default path, and that's the tricky point: When I launch node app.js it works, perfectly. The problem starts when I configured my Supervisord to run with the same user, with the same config file as I have in other systems working, and I get that NodeJS can't find hashlib. module.js:337 throw new Error("Cannot find module '" + request + "'"); ^ Error: Cannot find module 'hashlib' I'm getting crazy, what can I do?! Why my user launching node from the console works great, but not the supervisord? Thanks!

  • Allow access to WordPress site only by links in email newsletters

    - by Shane
    I send out a personal email newsletter, and have been looking into sending it via some service like MailChimp, or sendy.co. Many of these email services suggest, or require, the email newsletter content to be available online, in case the recipient's email app doesn't render it properly, or at all. The thing is I don't want my newsletter contents visible to the whole world. Nor do I want to require existing recipients to make accounts/be assigned accounts, with passwords. So, the question is: How can my WordPress site content be viewable only by clicking on the link to it in the email newsletter. It can't be found in a Google search; but once at the site the visitor can view previous newsletter contents. It seems an .htaccess file would do the trick, but I have been unable to figure out the syntax for this. Thanks for your help. I have copied below two other questions, and answers, which have helped me word my question clearly. Similar to this request about allowing access to a certain group while still restricting access to the world: Is there a way to password protect directory only in cpanel. But the user should not be prompted the password, when they try to access it via web? This persons question is the closest I could find to my situation: Restrict direct folder access via .htaccess except via specific links

  • GNS3 Cannot ping/resolve DNS record

    - by Eldad Cohen
    I set up an internet lab with GNS3, which has 3 routers, in each node there is a computer directly connected. One of the hosts is a DNS server, Windows 2003 Server. The other one is a Windows XP machine. Ping is good between routers and machines but no ability to ping domain.com record on DNS server 2003. I set a static nat on the router to route all traffic from gateway to the DNS server internal ip address, still no answer for the dns request. Any ideas or thoughts will be most welcome.

  • Certain users cannot get to my server

    - by Zeno
    I am finding more and more users that report they cannot reach my server (website or services). Their tracert from that user looks like this: Tracing route to domain.com [*.*.*.255] over a maximum of 30 hops: 1 * * * Request timed out. The server is up and functional and every else reports it is fine. But there are various users who cannot get to it. I have no firewall or anything that would block anyone. Yes, the last part of the server IP is 255. Could this be causing it? http://www.dslreports.com/forum/r18539206-Last-octet-255-bug-on-Windows Or would a certain ISP be denying traffic to my server? Or something on their router level?

  • Hosting multiple sites on a single webapp in tomcat

    - by satish
    Scenario: I have a website - www.mydomain.com. Registered users will be given the choice of getting a permanent url to their account on mydomain.com as a subdomain like (username.mydomain.com) or they can opt to have their own domain like www.userdomain.com. So the user can access his/her account through the subdomain URL or their own hostname and the request should be forwarded to a specific url on mydomain.com. For example: xyz.mydomain.com or www.xyz.com should give the user account from www.mydomain.com/webapp/account?id=xyz. The user should be completely unaware about where the content is coming from. Setup: My website is running as a webapp in tomcat 5.5.28 with apache as the web server. I am using a VPS which means I have control over all the configuration files (apache, tomcat and dns server). Can you tell me what are the configurations needed to achieve the above scenario??

  • when to use squid on server side?

    - by ajsie
    so i have set up apache serving my php pages. i read about squid but don't understand why/how i should use it to speed up my web server. from what i've learned squid is located in same network (or another) and caches content requested by the web browsers, and then when another web browser wants a same page, squid returns that page cached locally, so it never sends a request to the apache server (faster response time for the client, and reduced load for the server). so it seems that squid is for the client side (web browser), and has nothing to do with the server side (apache). but then some people tell others how they have speeded up apache using squid. so im confused. could squid be used on the server side too? and how will it work?

  • iproute2 premptive route creation, i think....

    - by Bryan Hunt
    Firstly: I know could do this the easy way with SSH but I want to learn how to route. I want to route packets back through the same tun0 interface from which they came into my system. I can do it for single routes. This works: sudo ip route add 74.52.23.120 metric 2 via 10.8.0.1 But i'd have to add them manually for each request that came down the pipe I've taken the blue pill and followed the http://lartc.org/howto/lartc.netfilter.html: Netfilter & iproute - marking packets tutorial But it's oriented towards redirecting OUTGOING packets based upon markers What I want is for a packet that comes in via tun0 not to be dropped which is what's happening right now, running scappy or suchlike to receive packets it doesn't seem to be receiving anything. Watching in wireshark I see the initial SYN packets coming in on the tun0 interface but that's as far as it gets without a static route as shown above. Am I nuts?

  • Apache Reverse Proxy server and SSL NTLM SharePoint

    - by user50211
    Hi, I'm trying to set Apache as proxy server to an internal SharePoint server. I have previously configured Apache to run as a proxy server to export internal webpages and web applications. However, the Sharepoint is using SSL and NTLM authentication, and this is new to me :( I have tried many options, the traffic seems to be forwared as I get the authentication popup window, but when I insert the user/pass, I get back to the same popup window. Anybody has configured Apache to do so?

  • Domain forwarding to a IE "trusted site" opens a blank page

    - by Michael Jasper
    My employer, a University, regularly hosts conferences and other events. While websites for these sites are hosted on our domain, they frequently request customized .com urls. We then forward these domains to the specific site. Recently, we discovered a problem, where a page will not load if the following conditions are met(using a current example): website is created on our CMS for a conference http://continue.weber.edu/nulc a domain is created http://www.nulc2012.com and forwarded to http://continue.weber.edu/nulc The user enters http://www.nulc2012.com into their address bar using IE7 or IE8 The user has *.weber.edu listed as a "trusted site" in IE security settings (the case for nearly all on-campus computers) When this happens, their browser will correctly transfer to the page http://continue.weber.edu/nulc/index.php, however the page is blank, returning only: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML><HEAD> <META content="text/html; charset=windows-1252" http-equiv=Content-Type></HEAD> <BODY></BODY></HTML> Is there any know solution to this problem? Or am I missing something completely? Note: Tested websites do load correctly in Chrome, Firefox, and Safari

  • Comparing the Performance of Visual Studio's Web Reference to a Custom Class

    As developers, we all make assumptions when programming. Perhaps the biggest assumption we make is that those libraries and tools that ship with the .NET Framework are the best way to accomplish a given task. For example, most developers assume that using ASP.NET's Membership system is the best way to manage user accounts in a website (rather than rolling your own user account store). Similarly, creating a Web Reference to communicate with a web service generates markup that auto-creates a proxy class, which handles the low-level details of invoking the web service, serializing parameters, and so on. Recently a client made us question one of our fundamental assumptions about the .NET Framework and Web Services by asking, "Why should we use proxy class created by Visual Studio to connect to a web service?" In this particular project we were calling a web service to retrieve data, which was then sorted, formatted slightly and displayed in a web page. The client hypothesized that it would be more efficient to invoke the web service directly via the HttpWebRequest class, retrieve the XML output, populate an XmlDocument object, then use XSLT to output the result to HTML. Surely that would be faster than using Visual Studio's auto-generated proxy class, right? Prior to this request, we had never considered rolling our own proxy class; we had always taken advantage of the proxy classes Visual Studio auto-generated for us. Could these auto-generated proxy classes be inefficient? Would retrieving and parsing the web service's XML directly be more efficient? The only way to know for sure was to test my client's hypothesis. Read More >

  • Setting up routing for MS DirectAccess to a VMWare EsXi Host

    - by Paul D'Ambra
    I'm trying to set up DirectAccess on a virtual machine so I can demonstrate it's value and then if need be add a physical machine to host it. I'm hitting a problem because the Direct Access machine (DA01) needs to have 2 public addresses actually configured on the external adapter but there is a Zyxel Zywall USG300 between the VMware ESXi host and the outside world. I've summarised my setup in this diagram If I ping from the LAN to 212.x.y.89 I get a response but if I ping from the VM I get destination host unreachable. I used "route add 212.x.y.89 192.c.d.1" and get request timed out. At that point I see outbound traffic allowed on the Zyxel firewall but nothing coming back. I'm past my understanding of routing and VMWare so am not sure how to tie down where my problem lies (or even if this setup is possible). So any help massively appreciated. Paul

  • Monitor network connectivity in WP7 apps

    - by Daniel Moth
    Most interesting Windows Phone apps rely on some network service for their functionality. So at some point in your app you may need to know programmatically if there is network connection available or not. For example, the Translator by Moth app relies on the Bing Translation service for translations. When a request for translation (text or voice) is made, the network call may fail. The failure reason is not evident from any of the return results, so I check the connection to see if it is present. Dependent on that, a different message is shown to the user. Before the translation phase is even reached, at the app start up time the Bing service is queried for its list of  languages; in that case I don't want to show the user a message and instead want to be notified when the network is available in order to send the query out again. So for those two requirements (which I imagine are common in other apps) I wrote a simple wrapper MyNetwork static class to the framework APIs: Call once MyNetwork.MonitorNetworkAvailability() method so it monitors the network change At any time check the MyNetwork.IsConnected property to check for network presence Subscribe to its MyNetwork.ConnectionEstablished event Optionally, during debugging use its MyNetwork.ChangeStatus method to simulate a change in network status As usual, there may be better ways to achieve this, but this class works perfectly for my scenarios. You can download the code here: MyNetworks.cs. Comments about this post welcome at the original blog.
