• How to intercept 401 from Forms Authentication in ASP.NET MVC?

  - by Jiho Han

  I would like to generate a 401 page if the user does not have the right permission. The user requests a url and is redirected to the login page (I have deny all anonymous in web.config). The user logs in successfully and is redirected to the original url. However, upon permission check, it is determined that the user does not have the required permission, so I would like to generate a 401. But Forms Authentication always handles 401 and redirects the user to the login page. To me, this isn't correct. The user has already authenticated, the user just does not have the proper authorization. In other scenarios, such as in ajax or REST service scenario, I definitely do not want the login page - I need the proper 401 page. So far, I've tried custom Authorize filter to return ViewResult with 401 but didn't work. I then tried a normal Action Filter, overriding OnActionExecuting, which did not work either. What I was able to do is handle an event in global.asax, PostRequestHandlerExecute, and check for the permission then write out directly to response: if (permissionDenied) { Context.Response.StatusCode = 401; Context.Response.Clear(); Context.Response.Write("Permission Denied"); Context.Response.Flush(); Context.Response.Close(); return; } That works but it's not really what I want. First of all, I'm not even sure if that is the right event or the place in the pipeline to do that. Second, I want the 401 page to have a little more content. Preferably, it should be an aspx page with possibly the same master page as the rest of the site. That way, anyone browsing the site can see that the permission is denied but with the same look and feel, etc. but the ajax or service user will get the proper status code to act on. Any idea how this can be achieved? I've seen other posts with similar requests but didn't see a solution that I can use. And no, I do not want a 403.

• Apache: How can i see my localhost on 192.168.1.101 from 192.168.1.102?

  - by takpar

  Hi, I'm running Apache on Ubuntu. My IP address is 192.168.1.101 While http://localhost and http://192.168.1.101 work fine in my PC, I cannot access it from within my laptop using http://192.168.1.102 It's strange. I can ping 192.168.1.101 but I got "The connection has timed out." in browser. I'm using default apache config. so this is what my sites-available/default looks like: NameVirtualHost *:80 <VirtualHost *:80> ServerAdmin webmaster@localhost DocumentRoot /home/www/public_html <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /home/www/public_html> Options Indexes FollowSymLinks MultiViews #AllowOverride None AllowOverride all Order allow,deny allow from all </Directory> /etc/apache2/posrts.conf NameVirtualHost *:80 Listen 80 <IfModule mod_ssl.c> # If you add NameVirtualHost *:443 here, you will also have to change # the VirtualHost statement in /etc/apache2/sites-available/default-ssl # to <VirtualHost *:443> # Server Name Indication for SSL named virtual hosts is currently not # supported by MSIE on Windows XP.

• ASP.NET 2.0 and 4.0 seem to treat the root url differently in Forms Authentication

  - by Kev

  If have the following web.config: <configuration> <system.web> <authentication mode="Forms"> <forms name="MembershipCookie" loginUrl="Login.aspx" protection="All" timeout="525600" slidingExpiration="true" enableCrossAppRedirects="true" path="/" /> </authentication> <authorization> <deny users="?" /> </authorization> </system.web> <location path="Default.aspx"> <system.web> <authorization> <allow users="*"/> </authorization> </system.web> </location> </configuration> The application is an ASP.NET 2.0 application running on Windows 2008R2/IIS7.5. If the site's application pool is configured to run ASP.NET 2.0 and I browse to http://example.com then Default.aspx is rendered as you'd expect from the rules above. However if the application pool is set to run ASP.NET 4.0 I am redirected to the login page. If I explicitly specify http://example.com/default.aspx then all is good and default.aspx renders. I've tried rewriting / -> /default.aspx (using IIS UrlRewriter 2.0) but the result is still the same, I get kicked to the login page. I've also tried this with an ASP.NET 4.0 application with the same result (which is where the problem initially arose). The reason I tried this with a 2.0 application was to see if there was a change in behaviour, and it seems that / is handled differently in 4.0. So to summarise, using the configuration above the following is observed: ASP.NET Version Url Behaviour ------------------------------------------------------------------------- 2.0 http://example.com Renders Default.aspx 2.0 http://example.com/Default.aspx Renders Default.aspx 4.0 http://example.com Redirects to Login.aspx 4.0 http://example.com/Default.aspx Renders Default.aspx Is this a bug/breaking change or have I missed something glaringly obvious?

• Turning off ASP.Net WebForms authentication for one sub-directory

  - by Keith

  I have a large enterprise application containing both WebForms and MVC pages. It has existing authentication and authorisation settings that I don't want to change. The WebForms authentication is configured in the web.config: <authentication mode="Forms"> <forms blah... blah... blah /> </authentication> <authorization> <deny users="?" /> </authorization> Fairly standard so far. I have a REST service that is part of this big application and I want to use HTTP authentication instead for this one service. So, when a user attempts to get JSON data from the REST service it returns an HTTP 401 status and a WWW-Authenticate header. If they respond with a correctly formed HTTP Authorization response it lets them in. The problem is that WebForms overrides this at a low level - if you return 401 (Unauthorised) it overrides that with a 302 (redirection to login page). That's fine in the browser but useless for a REST service. I want to turn off the authentication setting in the web.config: <location path="rest"> <system.web> <authentication mode="None" /> <authorization><allow users="?" /></authorization> </system.web> </location> The authorisation bit works fine, but when I try to change the authentication I get an exception: It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. I'm configuring this at application level though - it's in the root web.config How do I override the authentication so that all of the rest of the site uses WebForms authentication and this one directory uses none? This is similar to another question: 401 response code for json requests with ASP.NET MVC, but I'm not looking for the same solution - I don't want to just remove the WebForms authentication and add new custom code globally, there's far to much risk and work involved. I want to change just the one directory in configuration.

• What are the weaknesses of this user authentication method?

  - by byronh

  I'm developing my own PHP framework. It seems all the security articles I have read use vastly different methods for user authentication than I do so I could use some help in finding security holes. Some information that might be useful before I start. I use mod_rewrite for my MVC url's. Passwords are sha1 and md5 encrypted with 24 character salt unique to each user. mysql_real_escape_string and/or variable typecasting on everything going in, and htmlspecialchars on everything coming out. Step-by step process: Top of every page: session_start(); session_regenerate_id(); If user logs in via login form, generate new random token to put in user's MySQL row. Hash is generated based on user's salt (from when they first registered) and the new token. Store the hash and plaintext username in session variables, and duplicate in cookies if 'Remember me' is checked. On every page, check for cookies. If cookies set, copy their values into session variables. Then compare $_SESSION['name'] and $_SESSION['hash'] against MySQL database. Destroy all cookies and session variables if they don't match so they have to log in again. If login is valid, some of the user's information from the MySQL database is stored in an array for easy access. So far, I've assumed that this array is clean so when limiting user access I refer to user.rank and deny access if it's below what's required for that page. I've tried to test all the common attacks like XSS and CSRF, but maybe I'm just not good enough at hacking my own site! My system seems way too simple for it to actually be secure (the security code is only 100 lines long). What am I missing? I've also spent alot of time searching for the vulnerabilities with mysql_real_escape string but I haven't found any information that is up-to-date (everything is from several years ago at least and has apparently been fixed). All I know is that the problem was something to do with encoding. If that problem still exists today, how can I avoid it? Any help will be much appreciated.

• Asp.net login problem.

  - by Catarrunas

  Hello, im building a asp.net web site with 2.0 framework. I've been "fighting" with web.config, i've changed it quiet some times. So to start from scracht this is what i have: <?xml version="1.0" encoding="utf-16"?> <configuration> <connectionStrings> <remove name="LocalSqlServer"/> <add name="ABC" connectionString="Database=jsilvaqqc.mdf; Data Source=213.175.208.3;Initial Catalog=jsilvaqqc;User ID=jsilva;Password=joao123#;" providerName="System.Data.SqlClient"/> <add name="LocalSqlServer" connectionString="Database=jsilvaqqc.mdf; Data Source=213.175.208.3;Initial Catalog=jsilvaqqc;User ID=jsilva;Password=joao123#;" providerName="System.Data.SqlClient"/> </connectionStrings> <location path="Members"> <system.web> <authorization> <allow users="*"/> <deny users="?"/> </authorization> </system.web> </location> <system.web> <compilation debug="true"/> </system.web></configuration> It works fine im my machine. I've created the users for the login and the role to access the "Members" folder. But in my host company, it doesnt work. I have the aspnet database from my computer in that databese "jsilvaqqc.mdf". When i try to log on pops up box requiring autentication. But i've alreadu given that in the log in form. Do i need aspnet "authentication" tag? Why dont i need it in my machine if i access the same database? Thanks for you help.

• Call phpexcel from joomla

  - by Oscar Calderon

  i have a problem about phpexcel and joomla. I'm developing some filter form to load excel reports, so i used phpexcel library to do this. Right now i have only a report, it works fine, but after that i upload inside joomla using PHP pages component that allows me to put php files inside joomla and call it. When i put them, i change a little bit the form that calls the php that generates the excel report, i call the php using a link like this: h**p://www.whiblix.com/index.php?option=com_php&Itemid=24 That is, calling it from Joomla, not directly the php. If i wanna call the php directly i could use this path: h**p://www.whiblix.com/components/com_php/files/repImportaciones.php What's the problem? The problem is, when i call the php that generates the excel through joomla, the excel that is downloaded is corrupt and only shows symbols in one cell when i open it. But if i call the php directly the report is generated fine. I could call the php directly, the problem is that if i call it directly i can't use this line of code: defined( '_JEXEC' ) or die( 'Restricted access' ); That is used to deny the direct access to php from call it directly, because it doesn' work because the security. Where's the problem? This is the code of php that generates the report (ommiting the code where generates the rows and cells): <?php //defined( '_JEXEC' ) or die( 'Restricted access' ); /** Error reporting */ error_reporting(E_ALL); date_default_timezone_set('Europe/London'); require_once 'Classes/PHPExcel.php'; // Create new PHPExcel object $objPHPExcel = new PHPExcel(); // Set properties $objPHPExcel->getProperties()->setCreator("Maarten Balliauw") ->setLastModifiedBy("Maarten Balliauw") ->setTitle("Office 2007 XLSX Test Document") ->setSubject("Office 2007 XLSX Test Document") ->setDescription("Test document for Office 2007 XLSX, generated using PHP classes.") ->setKeywords("office 2007 openxml php") ->setCategory("Test result file"); // Rename sheet $objPHPExcel->getActiveSheet()->setTitle('Reporte de Importaciones'); // Set active sheet index to the first sheet, so Excel opens this as the first sheet $objPHPExcel->setActiveSheetIndex(0); // Redirect output to a client’s web browser (Excel5) header('Content-Type: application/vnd.ms-excel'); header('Content-Disposition: attachment;filename="repPrueba.xls"'); header('Cache-Control: max-age=0'); $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5'); $objWriter->save('php://output'); exit;

• php download file slows

  - by hobbywebsite

  OK first off thanks for your time I wish I could give more than one point for this question. Problem: I have some music files on my site (.mp3) and I am using a php file to increment a database to count the number of downloads and to point to the file to download. For some reason this method starts at 350kb/s then slowly drops to 5kb/s which then the file says it will take 11hrs to complete. BUT if I go directly to the .mp3 file my browser brings up a player and then I can right click and "save as" which works fine complete download in 3mins. (Yes both during the same time for those that are thinking it's my connection or ISP and its not my server either.) So the only thing that I've been playing around with recently is the php.ini and the .htcaccess files. So without further ado, the php file, php.ini, and the .htcaccess: download.php <?php include("config.php"); include("opendb.php"); $filename = 'song_name'; $filedl = $filename . '.mp3'; $query = "UPDATE songs SET song_download=song_download+1 WHER song_linkname='$filename'"; mysql_query($query); header('Content-Disposition: attachment; filename='.basename($filedl)); header('Content-type: audio/mp3'); header('Content-Length: ' . filesize($filedl)); readfile('/music/' . $filename . '/' . $filedl); include("closedb.php"); ?> php.ini register_globals = off allow_url_fopen = off expose_php = Off max_input_time = 60 variables_order = "EGPCS" extension_dir = ./ upload_tmp_dir = /tmp precision = 12 SMTP = relay-hosting.secureserver.net url_rewriter.tags = "a=href,area=href,frame=src,input=src,form=,fieldset=" ; Defines the default timezone used by the date functions date.timezone = "America/Los_Angeles" .htaccess Options +FollowSymLinks RewriteEngine on RewriteCond %{HTTP_HOST} !^(www.MindCollar.com)?$ [NC] RewriteRule (.*) http://www.MindCollar.com/$1 [R=301,L] <IfModule mod_rewrite.c> RewriteEngine On ErrorDocument 404 /errors/404.php ErrorDocument 403 /errors/403.php ErrorDocument 500 /errors/500.php </IfModule> Options -Indexes Options +FollowSymlinks <Files .htaccess> deny from all </Files> thanks for you time

• AuthenticationForm - cookie cross site

  - by bit

  I've 2 web site, the first one myFirst.domain.com and the second one mySecondSite.domain.com. They stay on two different web server and my goal is allow a cross site authentication (my real need is shared authenticationForm Cookie). I've correctly setted web config (machine key node, forms node). The only different is about loginUrl where on myFirstSite appears like "~/login.aspx", instead on mySecondSite it appears like "http://myFirstSite.com/login.aspx". Note that I've not a virtual directory, I've just 2 different web apps. The problem: When I reach myFirstSite login page from mySecondSite I never get redirect from login page, it seems like if cookie doesn't being written. The following is a few of snippet about the issue: MyFirsSite: <machineKey validationKey="..." decryptionKey="..." validation="SHA1" decryption="AES" /> <authentication mode="Forms"> <forms loginUrl="login.aspx" name="authCookie" enableCrossAppRedirects="true"></forms> </authentication> <authorization> <deny users="?" /> <allow users="*"/> </authorization> MyFirstSite code behind: FormsAuthenticationTicket fat = new FormsAuthenticationTicket(1, "userName..", DateTime.Now, DateTime.Now.AddMinutes(30), true, "roles.."); string ticket = FormsAuthentication.Encrypt(fat); HttpCookie authCookie = new HttpCookie(FormsAuthentication.FormsCookieName, ticket); authCookie.Expires = fat.Expiration; authCookie.Domain = "myDomain.com"; Response.Cookies.Add(authCookie); // here other stuff about querystring checking in order to execute exact redirect, however it's not work, I always return on login page MySecondSite: <machineKey validationKey="..." decryptionKey="..." validation="SHA1" decryption="AES"/> <authentication mode="Forms"> <forms loginUrl="http://myFirstSite.domain.com/login.aspx?queryStringToIndicateUrlPage" enableCrossAppRedirects="true"></forms> </authentication> <authorization> Well, that's all. Unfortunately it doesn't works. please, don't pay attention to "queryStringToIndicateUrlPage", it's only simple workaround in order to know whether I must redirect on the same app or on the another one.

• Lighttpd + fastcgi + python (for django) slow on first request

  I'm having a problem with a django website I host with lighttpd + fastcgi. It works great but it seems that the first request always takes up to 3seconds. Subsequent requests are much faster (<1s).

• Asterisk SIP digest authentication username mismatch

  - by Matt

  I have an asterisk system that I'm attempting to get to work as a backup for our 3com system. We already use it for a conference bridge. Our phones are the 3com 3C10402B, so I don't have the issue of older 3com phones that come without a SIP image. The 3com phones are communicating SIP with the Asterisk, but are unable to register because they present a digest username value that doesn't match what Asterisk thinks it should.

• Validating a linked item&rsquo;s data template in Sitecore

  - by Kyle Burns

  I’ve been doing quite a bit of work in Sitecore recently and last week I encountered a situation that it appears many others have hit.  I was working with a field that had been configured originally as a grouped droplink, but now needed to be updated to support additional levels of hierarchy in the folder structure.  If you’ve done any work in Sitecore that statement makes sense, but if not it may seem a bit cryptic.  Sitecore offers a number of different field types and a subset of these field types focus on providing links either to other items on the content tree or to content that is not stored in Sitecore.  In the case of the grouped droplink, the field is configured with a “root” folder and each direct descendant of this folder is considered to be a header for a grouping of other items and displayed in a dropdown.  A picture is worth a thousand words, so consider the following piece of a content tree: If I configure a grouped droplink field to use the “Current” folder as its datasource, the control that gets to my content author looks like this: This presents a nicely organized display and limits the user to selecting only the direct grandchildren of the folder root.  It also presents the limitation that struck as we were thinking through the content architecture and how it would hold up over time – the authors cannot further organize content under the root folder because of the structure required for the dropdown to work.  Over time, not allowing the hierarchy to go any deeper would prevent out authors from being able to organize their content in a way that it would be found when needed, so the grouped droplink data type was not going to fit the bill. I needed to look for an alternative data type that allowed for selection of a single item and limited my choices to descendants of a specific node on the content tree.  After looking at the options available for links in Sitecore and considering them against each other, one option stood out as nearly perfect – the droptree.  This field type stores its data identically to the droplink and allows for the selection of zero or one items under a specific node in the content tree.  By changing my data template to use droptree instead of grouped droplink, the author is now presented with the following when selecting a linked item: Sounds great, but a did say almost perfect – there’s still one flaw.  The code intended to display the linked item is expecting the selection to use a specific data template (or more precisely it makes certain assumptions about the fields that will be present), but the droptree does nothing to prevent the author from selecting a folder (since folders are items too) instead of one of the items contained within a folder.  I looked to see if anyone had already solved this problem.  I found many people discussing the problem, but the closest that I found to a solution was the statement “the best thing would probably be to create a custom validator” with no further discussion in regards to what this validator might look like.  I needed to create my own validator to ensure that the user had not selected a folder.  Since so many people had the same issue, I decided to make the validator as reusable as possible and share it here. The validator that I created inherits from StandardValidator.  In order to make the validator more intuitive to developers that are familiar with the TreeList controls in Sitecore, I chose to implement the following parameters: ExcludeTemplatesForSelection – serves as a “deny list”.  If the data template of the selected item is in this list it will not validate IncludeTemplatesForSelection – this can either be empty to indicate that any template not contained in the exclusion list is acceptable or it can contain the list of acceptable templates Now that I’ve explained the parameters and the purpose of the validator, I’ll let the code do the rest of the talking: 1: /// <summary> 2: /// Validates that a link field value meets template requirements 3: /// specified using the following parameters: 4: /// - ExcludeTemplatesForSelection: If present, the item being 5: /// based on an excluded template will cause validation to fail. 6: /// - IncludeTemplatesForSelection: If present, the item not being 7: /// based on an included template will cause validation to fail 8: /// 9: /// ExcludeTemplatesForSelection trumps IncludeTemplatesForSelection 10: /// if the same value appears in both lists. Lists are comma seperated 11: /// </summary> 12: [Serializable] 13: public class LinkItemTemplateValidator : StandardValidator 14: { 15: public LinkItemTemplateValidator() 16: { 17: } 18:   19: /// <summary> 20: /// Serialization constructor is required by the runtime 21: /// </summary> 22: /// <param name="info"></param> 23: /// <param name="context"></param> 24: public LinkItemTemplateValidator(SerializationInfo info, StreamingContext context) : base(info, context) { } 25:   26: /// <summary> 27: /// Returns whether the linked item meets the template 28: /// constraints specified in the parameters 29: /// </summary> 30: /// <returns> 31: /// The result of the evaluation. 32: /// </returns> 33: protected override ValidatorResult Evaluate() 34: { 35: if (string.IsNullOrWhiteSpace(ControlValidationValue)) 36: { 37: return ValidatorResult.Valid; // let "required" validation handle 38: } 39:   40: var excludeString = Parameters["ExcludeTemplatesForSelection"]; 41: var includeString = Parameters["IncludeTemplatesForSelection"]; 42: if (string.IsNullOrWhiteSpace(excludeString) && string.IsNullOrWhiteSpace(includeString)) 43: { 44: return ValidatorResult.Valid; // "allow anything" if no params 45: } 46:   47: Guid linkedItemGuid; 48: if (!Guid.TryParse(ControlValidationValue, out linkedItemGuid)) 49: { 50: return ValidatorResult.Valid; // probably put validator on wrong field 51: } 52:   53: var item = GetItem(); 54: var linkedItem = item.Database.GetItem(new ID(linkedItemGuid)); 55:   56: if (linkedItem == null) 57: { 58: return ValidatorResult.Valid; // this validator isn't for broken links 59: } 60:   61: var exclusionList = (excludeString ?? string.Empty).Split(','); 62: var inclusionList = (includeString ?? string.Empty).Split(','); 63:   64: if ((inclusionList.Length == 0 || inclusionList.Contains(linkedItem.TemplateName)) 65: && !exclusionList.Contains(linkedItem.TemplateName)) 66: { 67: return ValidatorResult.Valid; 68: } 69:   70: Text = GetText("The field \"{0}\" specifies an item which is based on template \"{1}\". This template is not valid for selection", GetFieldDisplayName(), linkedItem.TemplateName); 71:   72: return GetFailedResult(ValidatorResult.FatalError); 73: } 74:   75: protected override ValidatorResult GetMaxValidatorResult() 76: { 77: return ValidatorResult.FatalError; 78: } 79:   80: public override string Name 81: { 82: get { return @"LinkItemTemplateValidator"; } 83: } 84: }   In this blog entry, I have shared some code that I found useful in solving a problem that seemed fairly common.  Hopefully the next person that is looking for this answer finds it useful as well.

• Asterisk SIP digest authentication username mismatch

  - by Matt

  I have an asterisk system that I'm attempting to get to work as a backup for our 3com system. We already use it for a conference bridge. Our phones are the 3com 3C10402B, so I don't have the issue of older 3com phones that come without a SIP image. The 3com phones are communicating SIP with the Asterisk, but are unable to register because they present a digest username value that doesn't match what Asterisk thinks it should. As an example, here are the relevant lines from a successful registration from a soft phone: Server sends: WWW-Authenticate: Digest algorithm=MD5, realm="asterisk", nonce="1cac3853" Phone responds: Authorization: Digest username="2321", realm="asterisk", nonce="1cac3853", uri="sip:192.168.254.12", algorithm=md5, response="d32df9ec719817282460e7c2625b6120" For the 3com phone, those same lines look like this (and fails): Server sends: WWW-Authenticate: Digest algorithm=MD5, realm="asterisk", nonce="6c915c33" Phone responds: Authorization: Digest username="sip:[email protected]", realm="asterisk", nonce="6c915c33", uri="sip:192.168.254.12", opaque="", algorithm=MD5, response="a89df25f19e4b4598595f919dac9db81" Basically, Asterisk wants to see a username in the Digest username field of 2321, but the 3com phone is sending sip:[email protected].

• SQL SERVER – 3 Online SQL Courses at Pluralsight and Free Learning Resources

  - by pinaldave

  Usain Bolt is an inspiration for all. He broke his own record multiple times because he wanted to do better! Read more about him on wikipedia. He is great and indeed fastest man on the planet. Usain Bolt – World’s Fastest Man “Can you teach me SQL Server Performance Tuning?” This is one of the most popular questions which I receive all the time. The answer is YES. I would love to do performance tuning training for anyone, anywhere.  It is my favorite thing to do, and it is my favorite thing to train others in.  If possible, I would love to do training 24 hours a day, 7 days a week, 365 days a year.  To me, it doesn’t feel like a job. Of course, as much as I would love to do performance tuning 24/7/365, obviously I am just one human being and can only be in one place t one time.  It is also very difficult to train more than one person at a time, and it is difficult to train two or more people at a time, especially when the two people are at different levels.  I am also limited by geography.  I live in India, and adjust to my own time zone.  Trying to teach a live course from India to someone whose time zone is 12 or more hours off of mine is very difficult.  If I am trying to teach at 2 am, I am sure I am not at my best! There was only one solution to scale – Online Trainings. I have built 3 different courses on SQL Server Performance Tuning with Pluralsight. Now I have no problem – I am 100% scalable and available 24/7 and 365. You can make me say the same things again and again till you find it right. I am in your mobile, PC as well as on XBOX. This is why I am such a big fan of online courses.  I have recorded many performance tuning classes and you can easily access them online, at your own time.  And don’t think that just because these aren’t live classes you won’t be able to get any feedback from me.  I encourage all my viewers to go ahead and ask me questions by e-mail, Twitter, Facebook, or whatever way you can get a hold of me. Here are details of three of my courses with Pluralsight. I suggest you go over the description of the course. As an author of the course, I have few FREE codes for watching the free courses.

• Apache cyclic redirection problem

  - by slicedlime

  I have an extremely weird problem with one of my sites. I run a number of blogs off a single apache2 server with a shared wordpress install. Each site has a www.domain.com main domain, but a ServerAlias of domain.com. This works fine for all the blogs except one, which instead of redirecting to www.domain.com redirects to domain.com, causing a cyclic redirection. The configuration for each host looks like this: <VirtualHost *:80> ServerName www.domain.com ServerAlias domain.com DocumentRoot "/home/www/www.domain.com" <Directory "/home/www/www.domain.com"> Options MultiViews Indexes Includes FollowSymLinks ExecCGI AllowOverride All Order allow,deny Allow from all </Directory> </VirtualHost> As this didn't work, I tried a mod_rewrite rule for it, which still didn't redirect correctly. The weird thing here is that if i rewrite it to redirect to any other domain it will redirect correctly, even to another subdomain. So a rewrite rule for domain.com that redirects to foo.domain.com works, but not to www.domain.com. In the same way, trying to redirec to www.domain.com/foo/ ends me up with a redirection to domain.com/foo/. Even weirder, I tried setting up domain.com as a completely separate virtual host, and ran this php test script as index.php on it: <?php header('Location: http://www.domain.com/' . $_SERVER["request_uri"]); ?> Hitting domain.com still redirects to domain.com! Checking out the headers sent to the server verifies that I get exactly the redirect URL I wanted, except with the "www." stripped. The same script works like a charm if I replace www. with foo or redirect to any other domain. This has now foiled me for a long time. I've diffed the vhosts configs for a working domain and the faulty one, and the only difference is the domain name itself. I've diffed the .htaccess files for both sites, and the only difference is a path related to the sharing of wordpress installation for the blogs: php_value include_path ".:/home/www/www.domain.com/local/:/home/www/www.domain.com/" I searched through everything in /etc (including apache conf) for the domain name of the faulty host and found nothing weird, searched through everything in /etc for one of the working ones to make sure it didn't differ, I even went so far to check on the DNS setup of two domains to make sure there wasn't anything strange going on. Here's the response for the faulty one: user@localhost dir $ wget -S domain.com --2010-03-20 21:47:24-- http://domain.com/ Resolving domain.com... x.x.x.x Connecting to domain.com|x.x.x.x|:80... connected.

• Help me solve my problem with NPR Media Player

  - by Calcipher

  First of, let me apologize for this getting a bit technical. Several weeks ago, I found that while using NPR's media player (e.g. click on 'Listen to the Show' - this is what I've been using as a test) the stream would suddenly halt after a minute or three. I could not get the stream to restart without reloading the page. Now, I assumed this was an issue with NPR's player and Linux (or just a bug in their stuff in general) so I began to dig, the following is what I have tried to date (please note, the tldr; option is to skip to the latest thing as I think I know what is causing the problem). Note: All testing has been done, for consistency purposes, on a clean install of Chromium with no pluggins running. My machine is Ubuntu 10.10x64. First thing I always try, I disabled all firewall stuff on the system (UFW, default deny all, allow ssh). No change, firewall back up for all additional tests unless otherwise noted. In any case, UFW is stateful, so connections it started on a non-specified on different ports will continue to work. I deleted my ~/.macromeda and ~/.adobe folders, restarted (just to be sure) and tried. Program still froze. I decided the problem might be with my install of flash, so I purged the version I had (and the home folders again). I installed the x64 version of flash from a PPA. This had no effect. I decided that the problem might be with the version of flash, so I purged the x64 version and installed the standard x32 version that comes with Ubuntu. No luck. Back to the x64 version for consistency, I decided to set up a 64-bit mini 'clone' of my system in VirtualBox. I was able to run the media player with no problem. I rsynced (in archive mode) my home directory from my real machine to the virtual machine (with bridged networking, so it was fully visible on the network). I also used a few tricks to install ALL of the same software (and repositories) from the real machine to the virtual machine. I was still able to listen to the player. I decided that the problem was with my install (after all, it had gone through two major version upgrades). As I have /home/ on a separate partition it was easy to reinstall and use the same trick from #6 to have my system up and running again within about an hour. I continue to have issues with the NPR Media Player. By this point the weekend had come. At work, I use a wired connection while at home I use a wireless connection. For some reason I forgot that I was having problems and used the NPR Media Player over the weekend. Low and behold it worked just fine at home on wireless (note: for various reasons, I could not test this on wired at home). Following from #6, I decided that the problem was either something with the network at work or still something with my account. As the latter was easier to test, I created a new account on my system and used that at work. The Media Player worked. At a loss, I decided to watch the traffic with tshark (the text based brother of wireshark) - X's to protect the innocent, I am the XXX.24.200.XXX: sudo tshark -i eth0 -p -t a -R "ip.addr == XXX.24.200.XXX && ip.addr == XXX.166.98.XXX" As you would expect, there were tons and tons of packets, but each and every time the player froze, this is what I got 08:42:20.679200 XXX.166.98.XXX - XXX.24.200.XXX TCP macromedia-fcs 56371 [PSH, ACK] Seq=817686 Ack=6 Win=65535 Len=1448 TSV=495713325 TSER=396467 08:42:20.718602 XXX.24.200.XXX - XXX.166.98.XXX TCP [TCP ZeroWindow] 56371 macromedia-fcs [ACK] Seq=6 Ack=819134 Win=0 Len=0 TSV=396475 TSER=495713325 08:42:21.050183 XXX.166.98.XXX - XXX.24.200.XXX TCP [TCP ZeroWindowProbe] macromedia-fcs 56371 [ACK] Seq=819134 Ack=6 Win=65535 Len=1 TSV=495713362 TSER=396475 08:42:21.050221 XXX.24.200.XXX - XXX.166.98.XXX TCP [TCP ZeroWindowProbeAck] [TCP ZeroWindow] 56371 macromedia-fcs [ACK] Seq=6 Ack=819134 Win=0 Len=0 TSV=396508 TSER=495713362 08:42:21.680548 XXX.166.98.XXX - XXX.24.200.XXX TCP [TCP ZeroWindowProbe] macromedia-fcs 56371 [ACK] Seq=819134 Ack=6 Win=65535 Len=1 TSV=495713425 TSER=396508 08:42:21.680605 XXX.24.200.XXX - XXX.166.98.XXX TCP [TCP ZeroWindowProbeAck] [TCP ZeroWindow] 56371 macromedia-fcs [ACK] Seq=6 Ack=819134 Win=0 Len=0 TSV=396571 TSER=495713425 08:42:22.910354 XXX.166.98.XXX - XXX.24.200.XXX TCP [TCP ZeroWindowProbe] macromedia-fcs 56371 [ACK] Seq=819134 Ack=6 Win=65535 Len=1 TSV=495713548 TSER=396571 08:42:22.910400 XXX.24.200.XXX - XXX.166.98.XXX TCP [TCP ZeroWindowProbeAck] [TCP ZeroWindow] 56371 macromedia-fcs [ACK] Seq=6 Ack=819134 Win=0 Len=0 TSV=396694 TSER=495713548 08:42:25.340458 XXX.166.98.XXX - XXX.24.200.XXX TCP [TCP ZeroWindowProbe] macromedia-fcs 56371 [ACK] Seq=819134 Ack=6 Win=65535 Len=1 TSV=495713791 TSER=396694 08:42:25.340517 XXX.24.200.XXX - XXX.166.98.XXX TCP [TCP ZeroWindowProbeAck] [TCP ZeroWindow] 56371 macromedia-fcs [ACK] Seq=6 Ack=819134 Win=0 Len=0 TSV=396937 TSER=495713791 08:42:30.170698 XXX.166.98.XXX - XXX.24.200.XXX TCP [TCP ZeroWindowProbe] macromedia-fcs 56371 [ACK] Seq=819134 Ack=6 Win=65535 Len=1 TSV=495714274 TSER=396937 08:42:30.170746 XXX.24.200.XXX - XXX.166.98.XXX TCP [TCP ZeroWindowProbeAck] [TCP ZeroWindow] 56371 macromedia-fcs [ACK] Seq=6 Ack=819134 Win=0 Len=0 TSV=397420 TSER=495714274 08:42:39.801738 XXX.166.98.XXX - XXX.24.200.XXX TCP [TCP ZeroWindowProbe] macromedia-fcs 56371 [ACK] Seq=819134 Ack=6 Win=65535 Len=1 TSV=495715237 TSER=397420 08:42:39.801784 XXX.24.200.XXX - XXX.166.98.XXX TCP [TCP ZeroWindowProbeAck] [TCP ZeroWindow] 56371 macromedia-fcs [ACK] Seq=6 Ack=819134 Win=0 Len=0 TSV=398383 TSER=495715237 08:42:59.032648 XXX.166.98.XXX - XXX.24.200.XXX TCP [TCP ZeroWindowProbe] macromedia-fcs 56371 [ACK] Seq=819134 Ack=6 Win=65535 Len=1 TSV=495717160 TSER=398383 08:42:59.032696 XXX.24.200.XXX - XXX.166.98.XXX TCP [TCP ZeroWindowProbeAck] [TCP ZeroWindow] 56371 macromedia-fcs [ACK] Seq=6 Ack=819134 Win=0 Len=0 TSV=400306 TSER=495717160 08:43:00.267721 XXX.24.200.XXX - XXX.166.98.XXX TCP 56371 macromedia-fcs [FIN, ACK] Seq=6 Ack=819134 Win=0 Len=0 TSV=400430 TSER=495717160 08:43:00.267827 XXX.24.200.XXX - XXX.166.98.XXX TCP 56371 macromedia-fcs [RST, ACK] Seq=7 Ack=819134 Win=65535 Len=0 TSV=400430 TSER=495717160 So, as you can see, my machine is sending out a ZeroWindow packet (which I think means some buffer or another filled up) which causes the Media Player to halt (unfortunately, terminally - no controls on it really do anything anymore). Any ideas, at all, what would cause this? Why only on eth0 under my main account?

• set proxy in apache for XMPP chat

  - by Hunt

  I want to setup a proxy settings in Apache to use Facebook XMPP Chat So far I have setup ejabber server and I am able to access xmpp service using http://mydomain.com:5280/xmpp-http-bind I am able to create Jabber Account too. Now as I want to integrate Facebook XMPP chat , I want my server to sit in between client and chat.facebook.com because I want to implement Facebook chat and custom chat too. So I have read this article and come to know that I need to serve BOSH Service as a proxy in apache to access Facebook Chat service. So I don't know how to set up a proxy in a apache httpd.conf as I have tried following <Proxy *> Order deny,allow Allow from all </Proxy> ProxyPass /xmpp-httpbind http://www.mydomain.com:5280/xmpp-http-bind ProxyPassReverse /xmpp-httpbind http://www.mydomain.com:5280/xmpp-http-bind But whenever I request http://www.mydomain.com:5280/xmpp-http-bind from strophe.js I am getting following response from server <body type='terminate' condition='internal-server-error' xmlns='http://jabber.org/protocol/httpbind'> BOSH module not started </body> and server log says following E(<0.567.0:ejabberd_http_bind:1239) : You are trying to use BOSH (HTTP Bind) in host "chat.facebook.com", but the module mod_http_bind is not started in that host. Configure your BOSH client to connect to the correct host, or add your desired host to the configuration, or check your 'modules' section in your ejabberd configuration file. here is my existing settings of ejabberd.cfg , but still no luck {5280, ejabberd_http, [ {access,all}, {request_handlers, [ {["pub", "archive"], mod_http_fileserver}, {["xmpp-http-bind"], mod_http_bind} ]}, captcha, http_bind, http_poll, register, web_admin ]} ]}. in a module section {mod_http_bind, [{max_inactivity, 120}]}, and whenever i fire http://www.mydomain.com:5280/xmpp-http-bind url independently am getting following message ejabberd mod_http_bind An implementation of XMPP over BOSH (XEP-0206) This web page is only informative. To use HTTP-Bind you need a Jabber/XMPP client that supports it.

• Consistent PHP _SERVER variables between Apache and nginx?

  - by Alix Axel

  I'm not sure if this should be asked here or on ServerFault, but here it goes... I am trying to get started on nginx with PHP-FPM, but I noticed that the server block setup I currently have (gathered from several guides including the nginx Pitfalls wiki page) produces $_SERVER variables that are different from what I'm used to seeing in Apache setups. After spending the last evening trying to "fix" this, I decided to install Apache on my local computer and gather the variables that I'm interested in under different conditions so that I could try and mimic them on nginx. The Apache setup I've on my computer has only one mod_rewrite rule: RewriteEngine On RewriteCond %{SCRIPT_FILENAME} !-f RewriteCond %{SCRIPT_FILENAME} !-d RewriteRule ^(.*)$ /index.php/$1 [L] And these are the values I get for different request URIs (left is Apache, right is nginx): localhost/ - http://www.mergely.com/GnzBHRV1/ localhost/foo/bar/baz/?foo=bar - http://www.mergely.com/VwsT8oTf/ localhost/index.php/foo/bar/baz/?foo=bar - http://www.mergely.com/VGEFehfT/ What configuration directives would allow me to get similar values on requests handled by nginx? My current configuration in nginx is: server { listen 80; listen 443 ssl; server_name default; ssl_certificate /etc/nginx/certificates/dummy.crt; ssl_certificate_key /etc/nginx/certificates/dummy.key; root /var/www/default/html; index index.php index.html; autoindex on; location / { try_files $uri $uri/ /index.php; } location ~ /(?:favicon[.]ico|robots[.]txt)$ { log_not_found off; } location ~* [.]php { #try_files $uri =404; include fastcgi_params; fastcgi_pass unix:/var/run/php5-fpm.sock; fastcgi_index index.php; fastcgi_split_path_info ^(.+[.]php)(/.+)$; } location ~* [.]ht { deny all; } } And my fastcgi_params file looks like this: fastcgi_param PATH_INFO $fastcgi_path_info; fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info; fastcgi_param QUERY_STRING $query_string; fastcgi_param REQUEST_METHOD $request_method; fastcgi_param CONTENT_TYPE $content_type; fastcgi_param CONTENT_LENGTH $content_length; fastcgi_param SCRIPT_NAME $fastcgi_script_name; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_param REQUEST_URI $request_uri; fastcgi_param DOCUMENT_URI $document_uri; fastcgi_param DOCUMENT_ROOT $document_root; fastcgi_param SERVER_PROTOCOL $server_protocol; fastcgi_param GATEWAY_INTERFACE CGI/1.1; fastcgi_param SERVER_SOFTWARE nginx/$nginx_version; fastcgi_param REMOTE_ADDR $remote_addr; fastcgi_param REMOTE_PORT $remote_port; fastcgi_param SERVER_ADDR $server_addr; fastcgi_param SERVER_PORT $server_port; fastcgi_param SERVER_NAME $server_name; fastcgi_param HTTPS $https; I know that the try_files $uri =404; directive is commented and that it is a security vulnerability but, if I uncomment it, the third request (localhost/index.php/foo/bar/baz/?foo=bar) will return a 404. It's also worth noting that my PHP cgi.fix_pathinfo in On (contrary to what some of the guides recommend), if I try to set it to Off, I'm presented with a "Access denied." message on every PHP request. I'm running PHP 5.4.8 and nginx/1.1.19. I don't know what else to try... Help?

• nginx problem accessing virtual hosts

  - by Sc0rian

  I am setting up nginx as a reverse proxy. The server runs on directadmin and lamp stack. I have nginx running on port 81. I can access all my sites (including virtual ips) on the port 81. However when I forward the traffic from port 80 to 81, the virtual ips have a message saying "Apache is running normally". Server IPs are fine, and I can still access virtual IP's on 81. [root@~]# netstat -an | grep LISTEN | egrep ":80|:81" tcp 0 0 <virtual ip>:81 0.0.0.0:* LISTEN tcp 0 0 <virtual ip>:81 0.0.0.0:* LISTEN tcp 0 0 <serverip>:81 0.0.0.0:* LISTEN tcp 0 0 :::80 :::* LISTEN apache 24090 0.6 1.3 29252 13612 ?

• Multiple Homed Windows 2008 Server / Windows 7 Client

  - by Daniel Scott

  I have a small Windows 2008 network, with some Windows 7 clients. The clients are both laptops with docking stations and I would like them to communicate with the Windows 2008 server (for filesharing) through the wired network whilst they're docked. Internet connectivity for all machines (clients and server) is via a Wireless LAN, so the wireless adapter in the Windows 7 clients stays active while they're docked. When the laptops are un-docked, it would be nice to still be able to contact the windows 2008 server for print sharing (and slower file sharing) - hence the server also being on the wireless LAN. The windows 2008 server is running Active Directory, DHCP and DNS. It controls DHCP leases on the wired network and holds the DNS records for "myserver.mycompany.local", which is what the filesharing clients connect to. Ideally I'd like the DNS records to return the wired IP first so that this is the address that the laptops will attempt initially - but there doesn't seem to be a way to do that? At present the server's IP on the wireless LAN comes out of an nslookup above the wired Lan IP. The multi-homing works perfectly - but in the wrong order! Switch on the wireless lan and ping myserver and it goes to the wireless IP. Disable the wireless on the client and do the same ping again and after a couple of seconds it starts pinging the wired address. Does anyone have any suggestions on how to make this work in a predictable order? - or even if it can work. Alternative 1? If it can't work, then would this work: Remove the wireless adapter from the server, put a wireless router/bridge on the wired network (set up to route to/from the wireless LAN's subnet), then configure the clients with two routes to the (now) single IP of the server with metrics favouring direct communication over the wired LAN first? Alternative 2? Should I instead single-home the laptops so all of their connectivity is via the wired-LAN while they're docked? (and route via the windows 2008 server - or a dedicated wireless bridge/router)? My concern here is that I'd like undocking to be seamless - and if the clients are in the middle of downloading something from the internet I wouldn't want whatever they're doing interupted as they switch IP addresses onto the Wireless network. Perhaps this isn't the case and I'm concerned over nothing? Any thoughts? :) UPDATE I seem to have cracked it (at least DNS entries come out in the order I hope for - and pinging the server with various combinations of wired, wireless and both interfaces enabled uses the IP I want) ... I set the binding order of the NICs on the Server (which is acting as Domain Controller, DHCP and DNS server) so that the Wired NIC is before the Wireless adapter. (Start -- type "Network Interfaces" -- Select "View Network Connections" -- Press Alt to show classic dropdown menus -- Advanced -- Advanced Settings) Now, an nslookup (from the client) of the server's hostname returns the Wired IP first, followed by the Wireless IP. The wired IP now seems to be used whenever it's contactable. Incidentally, the metrics on the wired and wireless routes (on the client) also favour the wired LAN (based on Windows' automatically assigned metrics) - but this was always the case, even when I was having trouble getting the wired IP to be "favoured". I'm not entirely sure if this is coincidence - or if a DNS server running on Windows, handing back IP addresses for itself does actually take the binding order of it's own network interfaces into account? It would be interesting to hear from someone who can confirm or deny that (or confirm that the binding order on the server plays a role for some other reason?)

• after enabling mod ssl apache stops listening on port 80

  - by zensys

  I have an ubuntu 12.04 server with zend server CE installed. I now wanted to enable https but after the first steps according to the documentation, 'a2enmod ssl' and 'apache service restart', apache does not listen on 443 but neither on 80, according to netstat -tap | grep http(s)! This is what I see in my error log, but I can't make much of it: [Fri May 25 19:52:39 2012] [notice] caught SIGTERM, shutting down [Fri May 25 19:52:41 2012] [warn] Init: Session Cache is not configured [hint: SSLSessionCache] [Fri May 25 19:52:41 2012] [notice] ModSecurity for Apache/2.6.3 (http://www.modsecurity.org/) configured.

Perhaps I should take some additional steps to make apache listen 0n 443 but that it stops listening on 80 altogether I can't understand.

• Configuring Wireless on Cisco 851W

  - by Aequitarum Custos

  Either a powersurge or something caused our router's configuration to get wiped, and our last backup was before the wireless network was setup. We have not been able to reconfigure the wireless since then, so was curious if anyone here would be able to determine what configuration is needed. We are using a Cisco 851W running 12.4(15)T9 We would like to use WPA encryption, and have it on the same network as the rest of the office network. Config file is below: User Access Verification Building configuration...

• phpmyadmin login redirect fails with custom ssl port

  - by baraboom

  The server is running Ubuntu 10.10, Apache 2.2.16, PHP 5.3.3-1ubuntu9.3, phpMyAdmin 3.3.7deb5build0.10.10.1. Since this same server is also running Zimbra on port 443, I've configured apache to serve SSL on port 81. So far, I have one CMS script running on this virtual host successfully. However, when I access /phpmyadmin (set up with the default alias) on my custom ssl port and submit the login form, I am redirected to http://vhost.domain.com:81/index.php?TOKEN=foo (note the http:// instead of the https:// that the login url was using). This generates an Error 400 Bad Request complaining about "speaking plain HTTP to an SSL-enabled server port." I can then manually change the http:// to https:// in the URL and use phpmyadmin as expected. I was annoyed enough to spend an hour trying to fix it and now even more annoyed that I cannot figure it out. I've tried various things, including: Adding $cfg['PmaAbsoluteUri'] = 'https://vhost.domain.com:81/phpmyadmin/'; to the /usr/share/phpmyadmin/config.inc.php file but this did not correct the problem (even though /usr/share/phpmyadmin/libraries/auth/cookie.auth.lib.php looks like it should honor it and use it as the redirect). Adding $cfg['ForceSSL'] = 1; to the same config.inc.php but then apache spirals into an infinite redirect. Adding a rewrite rule to the vhost-ssl conf file in apache but I was unable to figure out the condition to use when http:// was present along with the correct ssl port of :81. Lots of googling. Here are the relevant Apache configuration pieces: /etc/apache2/ports.conf <IfModule mod_ssl.c> NameVirtualHost *:81 Listen 81 </IfModule> /etc/apache2/sites-enabled/vhost-nonssl <VirtualHost *:80> ServerAdmin webmaster@localhost ServerName vhost.domain.com DocumentRoot /home/xxx/sites/vhost/html RewriteEngine On RewriteCond %{HTTPS} off RewriteRule (.*) https://%{HTTP_HOST}:81%{REQUEST_URI} </Virtualhost> /etc/apache2/sites-enabled/vhost-ssl <VirtualHost *:81> ServerAdmin webmaster@localhost ServerName vhost.domain.com DocumentRoot /home/xxx/sites/vhost/html <Directory /> Options FollowSymLinks AllowOverride None AuthType Basic AuthName "Restricted Vhost" AuthUserFile /home/xxx/sites/vhost/.users Require valid-user </Directory> <Directory /home/xxx/sites/vhost/html/> Options -Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory> </VirtualHost> /etc/apache2/conf.d/phpmyadmin.conf Alias /phpmyadmin /usr/share/phpmyadmin (The rest of the default .conf truncated.) Everything in the apache config seems to work ok - the rewrite from non-ssl to ssl, the http authentication, the problem only happens when I am submitting the login form for phpmyadmin from https://vhost.domain.com:81/index.php. Other configs: The phpmyadmin config is completely default and the php.ini has only had some minor changes to memory and timeout limits. These seem to work fine, as mentioned, another php script runs with no problem and phpmyadmin works great once I manually enter in the correct schema after login. I'm looking for either a bandaid I can add to save me the trouble of manually entering in the https:// after login, a real fix that will make phpmyadmin behave as I think it should or some greater understanding of why my desired config is not possible.
