  • Servers - Buying New vs Buying Second-hand

    - by Django Reinhardt
    We're currently in the process of adding additional servers to our website. We have a pretty simple topology planned: A Firewall/Router Server infront of a Web Application Server and Database Server. Here's a simple (and technically incorrect) diagram that I used in a previous question to illustrate what I mean: We're now wondering about the specs of our two new machines (the Web App and Firewall servers) and whether we can get away with buying a couple of old servers. (Note: Both machines will be running Windows Server 2008 R2.) We're not too concerned about our Firewall/Router server as we're pretty sure it won't be taxed too heavily, but we are interested in our Web App server. I realise that answering this type of question is really difficult without a ton of specifics on users, bandwidth, concurrent sessions, etc, etc., so I just want to focus on the general wisdom on buying old versus new. I had originally specced a new Dell PowerEdge R300 (1U Rack) for our company. In short, because we're going to be caching as much data as possible, I focussed on Processor Speed and Memory: Quad-Core Intel Xeon X3323 2.5Ghz (2x3M Cache) 1333Mhz FSB 16GB DDR2 667Mhz But when I was looking for a cheap second-hand machine for our Firewall/Router, I came across several machines that made our engineer ask a very reasonable question: If we stuck a boat load of RAM in this thing, wouldn't it do for the Web App Server and save us a ton of money in the process? For example, what about a second-hand machine with the following specs: 2x Dual-Core AMD Opteron 2218 2.6Ghz (2MB Cache) 1000Mhz HT 16GB DDR2 667Mhz Would it really be comparable with the more expensive (new) server above? Our engineer postulated that the reason companies upgrade their servers to newer processors is often because they want to reduce their power costs, and that a 2.6Ghz processor was still a 2.6Ghz processor, no matter when it was made. Benchmarks on various sites don't really support this theory, but I was wondering what server admin thought. Thanks for any advice.

  • How to make Thunderbird play nice with Google mail

    - by Christi
    Thunderbird and gmail aren't exactly the best of friends. Gmail's tags mean that Thunderbird often downloads multiple copies of a single mail. Anything tagged in gmail will appear in a folder related to that tag, the "all mail" folder, and possibly the "inbox" and "sent mail" folders too. Thus a mail with multiple tags could potentially be stored more than four times in a local Thunderbird cache. This can make searching difficult, and is obviously wasteful of disk space. The best solution I have come up with is as follows. Operate a zero inbox policy (i.e. use the inbox for processing live mail only and archive everything else) which eliminates an extra copy in the inbox. Secondly, configure Thunderbird not to sync the "Sent Mail" folder - this is a bit of a pain, since I actually find it quite useful to be able to look through just the mails I've sent, but a search can duplicate this functionality. In this way, most of the duplicates are removed, and only mail with tags is stored locally more than once. Ideally, however, I'd only like one copy of each mail to be stored locally. I am surprised Thunderbird doesn't store mail by some sort of hashing algorithm to prevent precisely this problem - but it wouldn't be compatible with the way the folders are mirrored in a local directory structure, I suppose. Can anyone think of a better way to get Thunderbird to cache a Google mail account locally efficiently.

  • PHP Not Automatically Updating With ?reload=1

    - by user32007
    A friend built a ranking system on his site and I am trying to host in on mine via wordpress and godaddy. It updates for him but when I load it to my site, it works for 6 hours, but as soon as the reload is supposed to occur, it errors and I get a 500 timeout error. His page is at: jeremynoeljohnson .com/yakezieclub My page is currently at http://sweatingthebigstuff.com/yakezieclub but when you ?reload=1 it will give the error. Any idea why this might be happening? Any settings that I might need to change? Here is the top of the index.php file. I'm not sure which part of any of it is messing up. I literally uploaded the same code as him. Here's the reload part: $cachefile = "rankings.html"; $daycachefile = "rankings_history.xml"; $cachetime = (60 * 60) * 6; // every 6 hours, the cache refreshes $daycachetime = (60 * 60) * 24; // every 24 hours, the history will be written to - or whenever the page is requested after 24 hours has passed $writenewdata = false; if (!empty($_GET['reload'])) { if ($_GET['reload']== 1) { $cachetime = 1; } } if (!empty($_GET['reloadhistory'])) { if ($_GET['reloadhistory'] == 1) { $daycachetime = 1; $cachetime = 1; } } if (file_exists($daycachefile) && (time() - $daycachetime < filemtime($daycachefile))) { // Do nothing } else { $writenewdata = true; $cachetime = 1; } // Serve from the cache if it is younger than $cachetime if (file_exists($cachefile) && (time() - $cachetime < filemtime($cachefile))) { include($cachefile); echo ""; exit; } ob_start(); // start the output buffer ?

  • What I should know about memory management?

    first of all: I don't use stackadmin or similar so please don't vote for moving there, I'm reading man top and paper "what every programmer should know about memory ..." I need really simple explanation like for retard ;) Having following top dump: top - 11:21:19 up 37 days, 21:16, 4 users, load average: 0.41, 0.75, 1.09 Tasks: 313 total, 5 running, 308 sleeping, 0 stopped, 0 zombie Cpu(s): 0.4%us, 0.6%sy, 0.9%ni, 96.2%id, 0.1%wa, 0.0%hi, 1.9%si, 0.0%st Mem: 132103848k total, 131916948k used, 186900k free, 54000k buffers Swap: 73400944k total, 73070884k used, 330060k free, 13931192k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 3305 tudb 25 10 144m 52m 940 R 6.0 0.0 1306:09 app 3011 tudb 15 0 71528 19m 604 S 3.3 0.0 171:57.83 app 3373 tudb 25 10 209m 93m 940 S 3.0 0.1 1074:53 app 3338 tudb 25 10 144m 47m 940 R 2.7 0.0 780:48.48 app 4227 tudb 25 10 208m 99m 904 S 1.3 0.1 198:56.01 app 8506 tudb 25 10 80.7g 49g 932 S 2.0 39.6 458:31.22 app I'm wondering what is: RES (my expl. physical memory consumption ? see 49GB) VIRT (memory mapped disk to cache? see 80GB) SHR (shared pages?) Swap: (is this cached label - for memory mapped disk into swap cache?) Should sum of RES give MEM: X used? or maybe sum of VIRT?

  • sporadic routing to another website when opening a common url

    - by user226098
    I have a strange problem in our office: Sometimes when opening a url from one of our projects random url in any browser not the right website shows up but some other website. In most of the cases it redirects to google.com with some parameters like https://www.google.de/?gfe_rd=cr&ei=krOOU8_kGcSKswadyYDQBw&gws_rd=ssl or just the ugly google 404 page). But today it remains on the origial url but shows up the the content of http://debug.netdna-cdn.com/. This happens about 1 time a week and for no apparent reason. Even stranger it only occurs on a single pc in the network. It now happens on two different computers in the network. Both use windows 8. The problem cannot be fixed by clearing the browser cache but by rebooting the pc or using ipconfig /flushdns. So I think it has something to do with the dns cache of the machine. But I have no idea what the reason is for this and how i can figure out how to solve it. Any ideas?

  • CentOS server. What does it mean when the total used RAM does not equal the sum of RES?

    - by Michael Green
    I'm having a problem with a virtual hosted server running CentOS. In the past month a process (java based) that had been running fine started having problems getting memory when the JVM was started. One strange thing I've noticed is that when I start the process, the PID says it is using 470mb of RAM while the 'used' memory immediately drops by over a 1GB. If I run 'top', the total RES used across all processes falls short of the 'used' listed at the top by almost 700mb. The support person says this means I have a memory leak with my process. I don't know what to believe because I would expect a memory leak to simply waste the memory the process is allocated not to consume additional memory that doesn't show up using 'top'. I'm a developer and not a server guy so I'm appealing to the experts. To me, if the total RES memory doesn't add up to the total 'used' it indicates that something is wrong with my virtual server set-up. Would you also suspect a memory leaking java process in this case? If I use free before: total used free shared buffers cached Mem: 2097152 149264 1947888 0 0 0 -/+ buffers/cache: 149264 1947888 Swap: 0 0 0 free after: total used free shared buffers cached Mem: 2097152 1094116 1003036 0 0 0 -/+ buffers/cache: 1094116 1003036 Swap: 0 0 0 So it looks as though the process is using (or causing to be used) nearly 1GB of RAM. Since the process (based on top is only using 452mb, does that mean that the kernal is all of a sudden using an additional 500mb?

  • Performance-optimizing Oracle 10g on a server that is also a Tomcat JSP app server?

    - by PKHunter
    I have inherited a simple RedHat 5 - 64bit platform. It has SCSI disks on RAID1, with 16GB of RAM. Double Core CPU. Oracle 10g, Release 2. This would be a decent platform for running the DB only, perhaps, but the same server in an "A-A mode" clustering (very simple) also runs Tomcat and there are several Java servlets running on this. Sadly there is no caching platform etc. We only use an external CDN for some html caching. I am personally more familiar with web environments on the LAMPP platform (apache, php, mysql, postgresql). PROBLEM: Because the server has both Tomcat JSP/Java and Oracle 10g running on the same server, with no caching, I have some issues of the server going down. Often, sadly. QUESTION: What are my options in terms of improving performance of all these different apps? Connection Pooling? Example, in Postgresql world we have PgBouncer, which really helps things. Does Oracle have something similar? Or is there a famous Java-based external pooler that people use in production environments? (I'm not familiar with Java) Any "SQL cache" as in the MySQL and Postgresql world? Any other kind of application cache, as "APC" or "eAccelarator" in the PHP world? The "OSCache" stuff from the Java world (JSP thingie I found on Google: http://onjava.com/pub/a/onjava/2005/01/05/jspcache.html?page=2) ... What else? Sorry if this is a noob question. I have googled and googled, but problem is I don't know what to google for, other than the broad general concepts above. So if not full answers, I would even appreciate basic pointers and I am happy to JFGI myself. Thanks!

  • File exists but is unreadable by PHP

    - by Aron
    More than once I have ran into this issue: I have a cache file that is automatically generated by PHP. It contains some generated PHP code. However for some reason the file cannot be read and parsed by PHP. These are the symptoms: File actually exists on file system. Using Terminal you can navigate to the file, view its contents (which are fully intact), etcetc. PHP file_exists() will report that the file exists...which is correct since it does :) Then I include() the file. But when actually parsing the file, PHP will just consider it an empty file. No fatal error, just no PHP code actually executed. Again, its as if the file was completely empty (which I assure you, it is not)... It is not a permissions issue. Permissions are set as needed. Workaround: open the file in Terminal via 'nano' or some other text editor and just save it to the disk again. After that (despite no changes to the content) PHP will run it just fine... As a clarification, I'd like to add that this happens rarely, but frequently enough to be a problem. And even when it does, there are hundreds of other similar files on the same system that work without a problem... If this were an issue affecting only my own scripts, I would consider that there must be a bug in the way I generate the PHP code. But no, the issue has occurred more than once when deploying to a server (usually from Beanstalk repository via FTP). The issue has been present on various servers, Debian and Ubuntu running Zend Community Server. Any ideas? One that crossed my mind was opcode cache-ing (part of Zend Server CE)...could it be that an empty version of the file is cached if it is requested while the write operation is still in progress?

  • Java games applet not connecting to Yahoo

    - by Steve
    Hi. I am trying to play a Y! game which use a java applet. The applet displays the message: Alert. Unable to connect to server. One of four things could have caused this: 1) You are behind a firewall. 2) You are not connected to the internet. 3) The games server is down. 4) You have a stale page in your cache. I have added an exception to the Windows firewall for java.exe. I am obviously connected to the Internet okay. The games server is not down when I am at home. I doubt it is down when I am at work. I have never successfully loaded this page before, so I doubt I have a stale page in cache. Could it be the corporate firewall? Nothing else in my web browser has been blocked before. Maybe the java applet connects on a different port to the browser. What should I test?

  • Why won't Google Chrome open Google Docs, and why is it slow with GMail?

    - by Philip
    OSX 10.6 Snow Leopard: Google Chrome works like a charm most of the time. I have many extensions installed, and I've tried disabling/re-enabling them one by one to find a culprit, with no luck. Here are the problems: (1) Chrome is slow to load GMail. I am fairly sure that clearing the cache alleviates this problem. But I can open Safari, type in the URL, and login to GMail in the time it sometimes takes Chrome to open the page. Shouldn't caching help the page load?!? And sometimes even after recent cache clears it still is slow to load..... Thoughts? (2) Chrome won't open Google Docs at all. Safari does. Again, I tried disabling extensions one-by-one, and I allow cookies and even third-party cookies. But I still am told it has a redirect loop. Any help would be much appreciated. Thanks!

  • How much free memory should I have on my webserver?

    - by neanderslob
    I have a webserver that's currently hosting two Wordpress sites and some java-based collaboration software. The server has 2G of memory and is currently using about 1.8G of the available memory. Right now what's on here is pretty much a pilot project that's getting negligible traffic so I think it's pretty clear that I'll be needing more memory. I was wondering, if I was to release it, how I might anticipate my memory needs based on the traffic it gets. I've poked around on Google and what I've found has been a bit tenuous. Is there a good heuristic that one should use when calculating memory demands as a function of the base (no traffic) load on the server? For reference, the output of free -m can be seen below: total used free shared buffers cached Mem: 2048 1832 215 0 0 0 -/+ buffers/cache: 1832 215 Swap: 0 0 0 To me this looks like actual memory used and isn't an illusion due to caching or anything else. I figure the demands of my collaboration software will have to be experimentally tested so here's free -m without that software running: total used free shared buffers cached Mem: 2048 1109 938 0 0 0 -/+ buffers/cache: 1109 938 Swap: 0 0 0 My plan B to figure this out is to add a bunch of swap space to the server, give it some traffic and adjust according the the amount that swap gets used. I was just wondering if anyone had a good rule of thumb to estimate how much memory I should plan on in advance...or if what I'm thinking is nuts. Many thanks in advance (I'm really quite new to this).

  • What are the best linux permissions to use for my website?

    - by Nic
    This is a Canonical Question about File Permissions on a Linux web server. I have a Linux web server running Apache2 that hosts several websites. Each website has its own folder in /var/www/. /var/www/contoso.com/ /var/www/contoso.net/ /var/www/fabrikam.com/ The base directory /var/www/ is owned by root:root. Apache is running as www-data:www-data. The Fabrikam website is maintained by two developers, Alice and Bob. Both Contoso websites are maintained by one developer, Eve. All websites allow users to upload images. If a website is compromised, the impact should be as limited as possible. I want to know the best way to set up permissions so that Apache can serve the content, the website is secure from attacks, and the developers can still make changes. One of the websites is structured like this: /var/www/fabrikam.com /cache /modules /styles /uploads /index.php How should the permissions be set on these directories and files? I read somewhere that you should never use 777 permissions on a website, but I don't understand what problems that could cause. During busy periods, the website automatically caches some pages and stores the results in the cache folder. All of the content submitted by website visitors is saved to the uploads folder.

  • Odd one: IE6 showing the "view source" command enabled when I was expecting it to be disabled.

    - by caerphilly
    Hi, OK, I admit this problem is odd. I'm just trying to understand why IE is behaving the way it is. I realise that logic may not apply here :) I have Internet Explorer 6 (Sp1) running on Windows 2000. The IE option "Do not store encrypted pages to disk" is checked (enabled). The temporary internet files folder is empty. TEMP and TMP environment variables are set to valid folders. I'm connected to a web server over SSL. The web server is serving a page over SSL with the HTTP cache-control header set to "no-cache, no-store". I was expecting the "view source" command to be greyed out in this circumstance (as it is on another machine). But it works. When I "view source", I get an entry in the Temporary Internet Files folder with an "internet address" property of "view-source:https://myserver/...." and the content of the page. I wasn't expecting that. I can't understand why one machine is different to another in this regard. Obviously there is some environment/setup difference, but I can't track it down. Anyone have any bright ideas?

  • Optimize Apache performance

    I'm looking for ways to optimize our current web server hosted in-house. I'm trying to supply as much relevant information below.

  • Microsoft Word 2008 on the Mac sometimes "Disappears" documents, really.

    - by Ross Charette
    This happens in a computer lab environment, has happened at least 3 times. We are running Microsoft Office 2008 for mac on Leopard, everything is updated. Our user's home directories are on a network drive, but the /Library/Cache folder is running locally. Typically a student will have a Word file that they have been working on, it's been saved before they even logged onto the computer that day. They log on, open the document, click the save icon (not go to File Save), sometimes even save multiple times, then close Word. The document is now gone. It's not hidden, there are no autosaves or anything in the Cache folder. Definitely not in the trash or trashes folder. It can't find it when you click on it in 'recent documents'. Searching meticulously though every folder in their home drive turns up nothing. They look using Finder, I look ssh'd as root into their home using ls -la. I look for similar files in case they renamed it by mistake. It's gone. Disappeared. Vaporized. It's happened to at least 3 different users in the past year. Much whining. Any idea?

  • Escaping %’s in file-/folder-names at the command-line

    - by Synetech
    Does anybody of a way to access files and directories that have a % in their name (which is valid) from the command-line? Specifically, if there are two %’s and the text between them happens to correspond to an environment variable. For example, if there is a file called C:\blah\%temp%.txt or a folder called C:\Program Files\%temp%\, none of the following will work because the variable gets expanded: > dir "c:\blah\%temp%.txt" > dir "c:\blah\^%temp^%.txt" > dir "c:\blah\%%temp%%.txt" > dir "c:\blah\\%temp\%.txt" > dir "c:\program files\%temp%" > dir "c:\program files\^%temp^%" > dir "c:\program files\%%temp%%" > dir "c:\program files\\%temp\%" Using wildcards will work, but does not uniquely select the file/folder and may include others: > dir "c:\blah\?temp?.txt"        (also shows ztempz.temp, 1tempa.txt, etc.) > dir "c:\program files\?temp?"   (likewise) (This is frustrating because every now and then—usually when Explorer is restarted for whatever reason—the environment variables stop expanding and some places where they are used end up creating files or directories with the environment variable in it. For example, because I configured Chromium to store its cache in a subdirectory of %temp%, if the variable expands, it is fine, but when it doesn’t, Chromium creates a directory called %temp% under its own directory and stores the cache—which can get large—there. I want to add a line to my temp-/junk-file cleaning script to automatically delete that folder if it exists, but I cannot figure out how to access it from the command-line without resorting to wildcards.)

  • Apache mod_disk_cache on a seperate drive

    - by pavs
    how can I set Apache mod_disk_cache on a separate drive from where the OS/Apache is installed? I have set up this on my apache2.conf: <IfModule mod_cache_disk.c> # cache cleaning is done by htcacheclean, which can be configured in # /etc/default/apache2 # # For further information, see the comments in that file, # /usr/share/doc/apache2/README.Debian, and the htcacheclean(8) # man page. # This path must be the same as the one in /etc/default/apache2 CacheRoot /media/cacheHD # This will also cache local documents. It usually makes more sense to # put this into the configuration for just one virtual host. CacheEnable disk / # The result of CacheDirLevels * CacheDirLength must not be higher than # 20. Moreover, pay attention on file system limits. Some file systems # do not support more than a certain number of inodes and # subdirectories (e.g. 32000 for ext3) CacheDirLevels 2 CacheDirLength 1 </IfModule> and it doesn't seem to be caching anything at all. The drive itself is a freshly installed ssd drive formatted with ext4.

  • Routing Issue in ASP.NET MVC 3 RC 2

    - by imran_ku07
         Introduction:             Two weeks ago, ASP.NET MVC team shipped the ASP.NET MVC 3 RC 2 release. This release includes some new features and some performance optimization. This release also fixes most of the bugs but still some minor issues are present in this release. Some of these issues are already discussed by Scott Guthrie at Update on ASP.NET MVC 3 RC2 (and a workaround for a bug in it). In addition to these issues, I have found another issue in this release regarding routing. In this article, I will show you the issue regarding routing and a simple workaround for this issue.       Description:             The easiest way to understand an issue is to reproduce it in the application. So create a MVC 2 application and a MVC 3 RC 2 application. Then in both applications, just open global.asax file and update the default route as below,     routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( "Default", // Route name "{controller}/{action}/{id1}/{id2}", // URL with parameters new { controller = "Home", action = "Index", id1 = UrlParameter.Optional, id2 = UrlParameter.Optional } // Parameter defaults );              Then just open Index View and add the following lines,    <%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage" %> <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> Home Page </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <% Html.RenderAction("About"); %> </asp:Content>             The above view will issue a child request to About action method. Now run both applications. ASP.NET MVC 2 application will run just fine. But ASP.NET MVC 3 RC 2 application will throw an exception as shown below,                  You may think that this is a routing issue but this is not the case here as both ASP.NET MVC 2 and ASP.NET MVC  3 RC 2 applications(created above) are built with .NET Framework 4.0 and both will use the same routing defined in System.Web. Something is wrong in ASP.NET MVC 3 RC 2. So after digging into ASP.NET MVC source code, I have found that the UrlParameter class in ASP.NET MVC 3 RC 2 overrides the ToString method which simply return an empty string.     public sealed class UrlParameter { public static readonly UrlParameter Optional = new UrlParameter(); private UrlParameter() { } public override string ToString() { return string.Empty; } }             In MVC 2 the ToString method was not overridden. So to quickly fix the above problem just replace UrlParameter.Optional default value with a different value other than null or empty(for example, a single white space) or replace UrlParameter.Optional default value with a new class object containing the same code as UrlParameter class have except the ToString method is not overridden (or with a overridden ToString method that return a string value other than null or empty). But by doing this you will loose the benefit of ASP.NET MVC 2 Optional URL Parameters. There may be many different ways to fix the above problem and not loose the benefit of optional parameters. Here I will create a new class MyUrlParameter with the same code as UrlParameter class have except the ToString method is not overridden. Then I will create a base controller class which contains a constructor to remove all MyUrlParameter route data parameters, same like ASP.NET MVC doing with UrlParameter route data parameters early in the request.     public class BaseController : Controller { public BaseController() { if (System.Web.HttpContext.Current.CurrentHandler is MvcHandler) { RouteValueDictionary rvd = ((MvcHandler)System.Web.HttpContext.Current.CurrentHandler).RequestContext.RouteData.Values; string[] matchingKeys = (from entry in rvd where entry.Value == MyUrlParameter.Optional select entry.Key).ToArray(); foreach (string key in matchingKeys) { rvd.Remove(key); } } } } public class HomeController : BaseController { public ActionResult Index(string id1) { ViewBag.Message = "Welcome to ASP.NET MVC!"; return View(); } public ActionResult About() { return Content("Child Request Contents"); } }     public sealed class MyUrlParameter { public static readonly MyUrlParameter Optional = new MyUrlParameter(); private MyUrlParameter() { } }     routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( "Default", // Route name "{controller}/{action}/{id1}/{id2}", // URL with parameters new { controller = "Home", action = "Index", id1 = MyUrlParameter.Optional, id2 = MyUrlParameter.Optional } // Parameter defaults );             MyUrlParameter class is a copy of UrlParameter class except that MyUrlParameter class not overrides the ToString method. Note that the default route is modified to use MyUrlParameter.Optional instead of UrlParameter.Optional. Also note that BaseController class constructor is removing MyUrlParameter parameters from the current request route data so that the model binder will not bind these parameters with action method parameters. Now just run the ASP.NET MVC 3 RC 2 application again, you will find that it runs just fine.             In case if you are curious to know that why ASP.NET MVC 3 RC 2 application throws an exception if UrlParameter class contains a ToString method which returns an empty string, then you need to know something about a feature of routing for url generation. During url generation, routing will call the ParsedRoute.Bind method internally. This method includes a logic to match the route and build the url. During building the url, ParsedRoute.Bind method will call the ToString method of the route values(in our case this will call the UrlParameter.ToString method) and then append the returned value into url. This method includes a logic after appending the returned value into url that if two continuous returned values are empty then don't match the current route otherwise an incorrect url will be generated. Here is the snippet from ParsedRoute.Bind method which will prove this statement.       if ((builder2.Length > 0) && (builder2[builder2.Length - 1] == '/')) { return null; } builder2.Append("/"); ........................................................... ........................................................... ........................................................... ........................................................... if (RoutePartsEqual(obj3, obj4)) { builder2.Append(UrlEncode(Convert.ToString(obj3, CultureInfo.InvariantCulture))); continue; }             In the above example, both id1 and id2 parameters default values are set to UrlParameter object and UrlParameter class include a ToString method that returns an empty string. That's why this route will not matched.            Summary:             In this article I showed you the issue regarding routing and also showed you how to workaround this problem. I explained this issue with an example by creating a ASP.NET MVC 2 and a ASP.NET MVC 3 RC 2 application. Finally I also explained the reason for this issue. Hopefully you will enjoy this article too.   SyntaxHighlighter.all()

  • Controlar Autentificaci&oacute;n Crystal Reports

    - by Jason Ulloa
    Para todos los que hemos trabajamos con Crystal Reports, no es un secreto que cuando tratamos de conectar nuestro reporte directamente a la base de datos, se nos viene encima el problema de autenticación. Es decir nuestro reporte al momento de iniciar la carga nos solicita autentificarnos en el servidor y sino lo hacemos, simplemente no veremos el reporte. Esto, además de ser tedioso para los usuarios se convierte en un problema de seguridad bastante grande, de ahí que en la mayoría de los casos se recomienda utilizar dataset. Sin embargo, para todos los que aún sabiendo esto no desean utilizar datasets, sino que, quieren conectar su crystal directamente veremos como implementar una pequeña clase que nos ayudará con esa tarea. Generalmente, cuando trabajamos con una aplicación web, nuestra cadena de conexión esta incluida en el web.config y también en muchas ocasiones contiene los datos como el usuario y password para acceder a la base de datos.  De esta cadena de conexión y estos datos es de los que nos ayudaremos para implementar la autentificación en el reporte. Generalmente, la cadena de conexión se vería así <connectionStrings> <remove name="LocalSqlServer"/> <add name="xxx" connectionString="Data Source=.\SqlExpress;Integrated Security=False;Initial Catalog=xxx;user id=myuser;password=mypass" providerName="System.Data.SqlClient"/> </connectionStrings>   Para nuestro ejemplo, nombraremos a nuestra clase CrystalRules (es solo algo que pensé de momento) 1. Primer Paso Creamos una variable de tipo SqlConnectionStringBuilder, a la cual le asignaremos la cadena de conexión que definimos en el web.config, y que luego utilizaremos para obtener los datos del usuario y el password para el crystal report. SqlConnectionStringBuilder builder = new SqlConnectionStringBuilder(ConfigurationManager.ConnectionStrings["xxx"].ConnectionString); 2. Implementación de propiedad Para ser más ordenados crearemos varias propiedad de tipo Privado, que se encargarán de recibir los datos de:   La Base de datos, el password, el usuario y el servidor private string _dbName; private string _serverName; private string _userID; private string _passWord;   private string dataBase { get { return _dbName; } set { _dbName = value; } }   private string serverName { get { return _serverName; } set { _serverName = value; } }   private string userName { get { return _userID; } set { _userID = value; } }   private string dataBasePassword { get { return _passWord; } set { _passWord = value; } } 3. Creación del Método para aplicar los datos de conexión Una vez que ya tenemos las propiedades, asignaremos a las variables los valores que se han recogido en el SqlConnectionStringBuilder. Y crearemos una variable de tipo ConnectionInfo para aplicar los datos de conexión. internal void ApplyInfo(ReportDocument _oRpt) { dataBase = builder.InitialCatalog; serverName = builder.DataSource; userName = builder.UserID; dataBasePassword = builder.Password;   Database oCRDb = _oRpt.Database; Tables oCRTables = oCRDb.Tables; //Table oCRTable = default(Table); TableLogOnInfo oCRTableLogonInfo = default(TableLogOnInfo); ConnectionInfo oCRConnectionInfo = new ConnectionInfo();   oCRConnectionInfo.DatabaseName = _dbName; oCRConnectionInfo.ServerName = _serverName; oCRConnectionInfo.UserID = _userID; oCRConnectionInfo.Password = _passWord;   foreach (Table oCRTable in oCRTables) { oCRTableLogonInfo = oCRTable.LogOnInfo; oCRTableLogonInfo.ConnectionInfo = oCRConnectionInfo; oCRTable.ApplyLogOnInfo(oCRTableLogonInfo);     }   }   4. Creación del report document y aplicación de la seguridad Una vez recogidos los datos y asignados, crearemos un elemento report document al cual le asignaremos el CrystalReportViewer y le aplicaremos los datos de acceso que obtuvimos anteriormente public void loadReport(string repName, CrystalReportViewer viewer) {   // attached our report to viewer and set database login. ReportDocument report = new ReportDocument(); report.Load(HttpContext.Current.Server.MapPath("~/Reports/" + repName)); ApplyInfo(report); viewer.ReportSource = report; } Al final, nuestra clase completa ser vería así public class CrystalRules { SqlConnectionStringBuilder builder = new SqlConnectionStringBuilder(ConfigurationManager.ConnectionStrings["Fatchoy.Data.Properties.Settings.FatchoyConnectionString"].ConnectionString);   private string _dbName; private string _serverName; private string _userID; private string _passWord;   private string dataBase { get { return _dbName; } set { _dbName = value; } }   private string serverName { get { return _serverName; } set { _serverName = value; } }   private string userName { get { return _userID; } set { _userID = value; } }   private string dataBasePassword { get { return _passWord; } set { _passWord = value; } }   internal void ApplyInfo(ReportDocument _oRpt) { dataBase = builder.InitialCatalog; serverName = builder.DataSource; userName = builder.UserID; dataBasePassword = builder.Password;   Database oCRDb = _oRpt.Database; Tables oCRTables = oCRDb.Tables; //Table oCRTable = default(Table); TableLogOnInfo oCRTableLogonInfo = default(TableLogOnInfo); ConnectionInfo oCRConnectionInfo = new ConnectionInfo();   oCRConnectionInfo.DatabaseName = _dbName; oCRConnectionInfo.ServerName = _serverName; oCRConnectionInfo.UserID = _userID; oCRConnectionInfo.Password = _passWord;   foreach (Table oCRTable in oCRTables) { oCRTableLogonInfo = oCRTable.LogOnInfo; oCRTableLogonInfo.ConnectionInfo = oCRConnectionInfo; oCRTable.ApplyLogOnInfo(oCRTableLogonInfo);     }   }   public void loadReport(string repName, CrystalReportViewer viewer) {   // attached our report to viewer and set database login. ReportDocument report = new ReportDocument(); report.Load(HttpContext.Current.Server.MapPath("~/Reports/" + repName)); ApplyInfo(report); viewer.ReportSource = report; }       #region instance   private static CrystalRules m_instance;   // Properties public static CrystalRules Instance { get { if (m_instance == null) { m_instance = new CrystalRules(); } return m_instance; } }   public DataDataContext m_DataContext { get { return DataDataContext.Instance; } }     #endregion instance   }   Si bien, la solución no es robusta y no es la mas segura. En casos de uso como una intranet y cuando estamos contra tiempo, podría ser de gran ayuda.

  • Trouble determining proper decoding of a REST response from an ArcGIS REST service using IHttpModule

    - by Ryan Taylor
    First a little background on what I am trying to achieve. I have an application that is utilizing REST services served by ArcGIS Server and IIS7. The REST services return data in one of several different formats. I am requesting a JSON response. I want to be able to modify the response (remove or add parameters) before the response is sent to the client. However, I am having difficulty converting the stream to a string that I can modify. To that end, I have implemented the following code in order to try to inspect the stream. SecureModule.cs using System; using System.Web; namespace SecureModuleTest { public class SecureModule : IHttpModule { public void Init(HttpApplication context) { context.BeginRequest += new EventHandler(OnBeginRequest); } public void Dispose() { } public void OnBeginRequest(object sender, EventArgs e) { HttpApplication application = (HttpApplication) sender; HttpContext context = application.Context; HttpRequest request = context.Request; HttpResponse response = context.Response; response.Filter = new ServicesFilter(response.Filter); } } } ServicesFilter.cs using System; using System.IO; using System.Text; namespace SecureModuleTest { class ServicesFilter : MemoryStream { private readonly Stream _outputStream; private StringBuilder _content; public ServicesFilter(Stream output) { _outputStream = output; _content = new StringBuilder(); } public override void Write(byte[] buffer, int offset, int count) { _content.Append(Encoding.UTF8.GetString(buffer, offset, count)); using (TextWriter textWriter = new StreamWriter(@"C:\temp\content.txt", true)) { textWriter.WriteLine(String.Format("Buffer: {0}", _content.ToString())); textWriter.WriteLine(String.Format("Length: {0}", buffer.Length)); textWriter.WriteLine(String.Format("Offset: {0}", offset)); textWriter.WriteLine(String.Format("Count: {0}", count)); textWriter.WriteLine(""); textWriter.Close(); } // Modify response _outputStream.Write(buffer, offset, count); } } } The module is installed in the /ArcGIS/rest/ virtual directory and is executed via the following GET request. http://localhost/ArcGIS/rest/services/?f=json&pretty=true The web page displays the expected response, however, the text file tells a very different (encoded?) story. Expect Response {"currentVersion" : "10.0", "folders" : [], "services" : [ ] } Text File Contents Buffer: ? ?`I?%&/m?{J?J??t??`$?@??????iG#)?*??eVe]f@????{???{???;?N'????\fdl??J??!????~|?"~?G?u]???'?)??G?????G??7N????W??{?????,??|?OR????q?

How might I decode, unzip, and otherwise convert the byte stream into the string I know it should be for modification by my filter?

  • PHP curl post to login to wordpress

    - by Sadi
    I followed http://stackoverflow.com/questions/724107 to login to wordpress, using php_curl, and it works fine as far I use WAMP, (apache/php). But when it comes to IIS on the dedicated server, it returns nothing. I have wrote the following function which is working fine on my local wamp, but when deployed to client's dedicated windows server 2k3, it doesn't.

  • CURL - HTTPS Wierd error

    - by Vincent
    All, I am having trouble requesting info from HTTPS site using CURL and PHP. I am using Solaris 10. It so happens that sometimes it works and sometimes it doesn't. I am not sure what is the cause. If it doesn't work, this is the entry recorded in the verbose log: * About to connect() to 10.10.101.12 port 443 (#0) * Trying 10.10.101.12... * connected * Connected to 10.10.101.12 (10.10.101.12) port 443 (#0) * error setting certificate verify locations, continuing anyway: * CAfile: /etc/opt/webstack/curl/curlCA CApath: none * error:80089077:lib(128):func(137):reason(119) * Closing connection #0 If it works, this is the entry recorded in the verbose log: * About to connect() to 10.10.101.12 port 443 (#0) * Trying 10.10.101.12... * connected * Connected to 10.10.101.12 (10.10.101.12) port 443 (#0) * error setting certificate verify locations, continuing anyway: * CAfile: /etc/opt/webstack/curl/curlCA CApath: none * SSL connection using DHE-RSA-AES256-SHA * Server certificate: * subject: C=CA, ST=British Columnbia, L=Vancouver, O=google, OU=FDN, CN=g.googlenet.com, [email protected] * start date: 2007-07-24 23:06:32 GMT * expire date: 2027-09-07 23:06:32 GMT * issuer: C=US, ST=California, L=Sunnyvale, O=Google, OU=Certificate Authority, CN=support, [email protected] * SSL certificate verify result: unable to get local issuer certificate (20), continuing anyway. > POST /gportal/gpmgr HTTP/1.1^M Host: 10.10.101.12^M Accept: */*^M Accept-Encoding: gzip,deflate^M Content-Length: 1623^M Content-Type: application/x-www-form-urlencoded^M Expect: 100-continue^M ^M < HTTP/1.1 100 Continue^M < HTTP/1.1 200 OK^M < Date: Wed, 28 Apr 2010 21:56:15 GMT^M < Server: Apache^M < Cache-Control: no-cache^M < Pragma: no-cache^M < Vary: Accept-Encoding^M < Content-Encoding: gzip^M < Content-Length: 1453^M < Content-Type: application/json^M < ^M * Connection #0 to host 10.10.101.12 left intact * Closing connection #0 My CURL options are as under: $ch = curl_init(); $devnull = fopen('/tmp/curlcookie.txt', 'w'); $fp_err = fopen('/tmp/verbose_file.txt', 'ab+'); fwrite($fp_err, date('Y-m-d H:i:s')."\n\n"); curl_setopt($ch, CURLOPT_STDERR, $devnull); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_URL, $desturl); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false); curl_setopt($ch, CURLOPT_HEADER, false); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0); curl_setopt($ch, CURLOPT_CONNECTTIMEOUT,120); curl_setopt($ch, CURLOPT_AUTOREFERER, true); curl_setopt($ch, CURLOPT_ENCODING, 'gzip,deflate'); curl_setopt($ch, CURLOPT_POSTFIELDS, $postdata); curl_setopt($ch, CURLOPT_VERBOSE,1); curl_setopt($ch, CURLOPT_FAILONERROR, true); curl_setopt($ch, CURLOPT_STDERR, $fp_err); $ret = curl_exec($ch); Anybody has any idea, why it works sometimes but fails mostly?

  • 500 Internal Server Error with PHP application

    - by James
    I have written a PHP application using Windows and XAMPP. I've been trying to run it on Ubuntu 10.10 with Lighttpd 1.4.26. Parts of the application work fine, but whenever I try to log in, I get a 500 - Internal Server Error page.

  • Using UUIDs for cheap equals() and hashCode()

    - by Tom McIntyre
    I have an immutable class, TokenList, which consists of a list of Token objects, which are also immutable: @Immutable public final class TokenList { private final List<Token> tokens; public TokenList(List<Token> tokens) { this.tokens = Collections.unmodifiableList(new ArrayList(tokens)); } public List<Token> getTokens() { return tokens; } } I do several operations on these TokenLists that take multiple TokenLists as inputs and return a single TokenList as the output. There can be arbitrarily many TokenLists going in, and each can have arbitrarily many Tokens. These operations are expensive, and there is a good chance that the same operation (ie the same inputs) will be performed multiple times, so I would like to cache the outputs. However, performance is critical, and I am worried about the expense of performing hashCode() and equals() on these objects that may contain arbitrarily many elements (as they are immutable then hashCode could be cached, but equals will still be expensive). This led me to wondering whether I could use a UUID to provide equals() and hashCode() simply and cheaply by making the following updates to TokenList: @Immutable public final class TokenList { private final List<Token> tokens; private final UUID uuid; public TokenList(List<Token> tokens) { this.tokens = Collections.unmodifiableList(new ArrayList(tokens)); this.uuid = UUID.randomUUID(); } public List<Token> getTokens() { return tokens; } public UUID getUuid() { return uuid; } } And something like this to act as a cache key: @Immutable public final class TopicListCacheKey { private final UUID[] uuids; public TopicListCacheKey(TopicList... topicLists) { uuids = new UUID[topicLists.length]; for (int i = 0; i < uuids.length; i++) { uuids[i] = topicLists[i].getUuid(); } } @Override public int hashCode() { return Arrays.hashCode(uuids); } @Override public boolean equals(Object other) { if (other == this) return true; if (other instanceof TopicListCacheKey) return Arrays.equals(uuids, ((TopicListCacheKey) other).uuids); return false; } } I figure that there are 2^128 different UUIDs and I will probably have at most around 1,000,000 TokenList objects active in the application at any time. Given this, and the fact that the UUIDs are used combinatorially in cache keys, it seems that the chances of this producing the wrong result are vanishingly small. Nevertheless, I feel uneasy about going ahead with it as it just feels 'dirty'. Are there any reasons I should not use this system? Will the performance costs of the SecureRandom used by UUID.randomUUID() outweigh the gains (especially since I expect multiple threads to be doing this at the same time)? Are collisions going to be more likely than I think? Basically, is there anything wrong with doing it this way?? Thanks.
