• Developping an online music store

  - by Simon

  We need to develop an application to sell music online. No need to specify that all will be done quite legally and in so doing, we have to plan an interface to pay artists. However, we are confronted with a question: What is the best way to store music on the server? Should we save it on server's disk from a HTTP fileupload? Should we save via FTP or would it be wiser to save it in the database? No need to say that we need it to be the most safiest as possible. So maybe an https is required here. But, we what you think is the best way? Maybe other idea? Because in all HTTP case, upload songs (for administration) is quite long and boring, but easly linkable to a song that admin create in his web application comparativly to an FTP application to upload song on server and then list directory in admin part to link the correct uploaded song to the song informations in database. I know that its maybe not quite clear, it's because i'm french but tell me and I will try to explain part that you don't understand.

• Getting batch_action functionality in Symfony 1.0

  - by Alex Ciminian

  I'm currently working on a web app written in Symfony. I'm supposed to add an "export to CSV" feature in the backend/administration part of the app for some modules. In the list view, there should be an "Export" button which should provide the user with a csv file of the elements that are displayed (considering filtering criteria). I've created a method in the actions class of the module that takes a comma separated list of ids and generates the CSV, but I'm not really sure how to add the link to it in the view. The problem is that the view doesn't exist anywhere, it's generated on the fly from the data in the generator.yml configuration file. I've posted the relevant part of the file below. I'm new to Symfony, so any help would be appreciated :). Thanks, Alex Update list: display: [id, =name, indemn, _status, _participants, _approved_, created_at] title: Lista actiuni object_actions: _edit: ~ _delete: ~ actions: _create: ~ export_csv: name: Export to CSV action: CSVExport params: id=csvActionSubmit filters: [name, county_id, _status_filter, activity_id] fields: id: name: Nr. crt. ... Thanks to your advice, I've managed to add a button that is linked to my action. The problem is that I also need to send some parameters to the action, because I may not want all the elements - filters may have been used. Unfortunately, the project is using Symfony 1.0, which doesn't support batch_actions. Currently, I'm working around this with Javascript (I parse the DOM to get the numeric ids (from the display table) and then build the link for the button. I really think there could be a better way for this.

• Web Applications Development: Security practices for Application design

  - by Shyam

  Hi, As I am creating more web applications that are targeted for multiple users, I figured out that I have to start thinking about user management and security. At a glance and in my ideal world, all users belong to a group. Permissions and access is thus defined per group (and inherited by the users of that group). Logically, I have my group of administrators, which are identified with a level "7" (integer) clearance. A group of webusers have for example level "1". This in generally all works great for me, but I need some kind of list that I have to keep in mind how I secure my system, and some general practices. I am not looking for a specific environment; I want to learn the why's and how's. An example is privilege escalation. If someone would be able to "push" themselves inside a group with higher privileges, for example the Administration, how can I prevent this, or what measures should I take to have some sort of precaution? I don't like in that case to walk into a caveat. My question is basically: where can I find a good resource, list, policy, book that explains the security of web applications, the why's, the how's and readable if you don't have any experience in the realm of advanced security? I prefer a free resource, as I believe I couldn't be the first one who thought about this. Thank you for your answers, comments and feedback.

• Codeigniter return config file as array with autoload enabled

  - by Fverswijver

  So I'm using CodeIgniter to build a website and I've made it so that all my specific settings are stored in a config file that's automatically loaded. I've also built a page that loads the settings file, makes a nice little table and allows me to edit everything from that page, afterwards it saves the entire page again (I know I could've done the same with a database but I want to try it this way). My problem is that I can't seem to use this bit when autoloading of my config file is enabled, but when I disable autoloading I can't seem to manually load it, it never finds my variables. So what I'm doing here is just taking all values from the config file and putting them in a single array so I can pass this array onto my settings administration page (edit/show all settings). $this->config->load('site_settings', TRUE); $data['settings'] = $this->config->item('site_settings'); ... $this->load->view('template', $data); config/site_settings.php <?php if ( ! defined('BASEPATH')) exit('No direct script access allowed'); $config['header_img'] = './img/header/'; $config['copyright_text'] = 'Copyright Instituto Kabu'; $config['copyright_font'] = './system/fonts/motoroil.ttf'; $config['copyright_font_color'] = 'ffffff'; $config['copyright_font_size'] = '32';

• Where should global Application Settings be stored on Windows 7?

  - by Kerido

  Hi everybody, I'm working hard on making my product work seamlessly on Windows 7. The problem is that there is a small set of global (not user-specific) application settings that all users should be able to change. On previous versions I used HKLM\Software\__Company__\__Product__ for that purpose. This allowed Power Users and Administrators to modify the Registry Key and everything worked correctly. Now that Windows Vista and Windows 7 have this UAC feature, by default, even an Administrator cannot access the Key for writing without elevation. A stupid solution would, of course, mean adding requireAdministrator option into the application manifest. But this is really unprofessional since the product itself is extremely far from administration-related tasks. So I need to stay with asInvoker. Another solution could mean programmatic elevation during moments when write access to the Registry Key is required. Let alone the fact that I don't know how to implement that, it's pretty awkward also. It interferes with normal user experience so much that I would hardly consider it an option. What I know should be relatively easy to accomplish is adding write access to the specified Registry Key during installation. I created a separate question for that. This also very similar to accessing a shared file for storing the settings. My feeling is that there must be a way to accomplish what I need, in a way that is secure, straightforward and compatible with all OS'es. Any ideas?

• ASP .NET Added Event Handlers to buttons on Page_Load. Event handlers do not fire the first click, b

  - by John

  Background: I am customizing an existing ASP .NET / C# application. It has it's own little "framework" and conventions for developers to follow when extending/customizing its functionality. I am currently extending some of it's administrative functionality, to which the framework provides a contract to enforce implementation of the GetAdministrationInterface() method, which returns System.Web.UI.Control. This method is called during the Page_Load() method of the page hosting the GUI interface. Problem: I have three buttons in my GUI, each of which have been assigned an Event Handler. My administration GUI loads up perfectly fine, but clicking any of the buttons doesn't do what I expect them to do. However, when I click them a second time, the buttons work. I placed breakpoints at the the beginning of each event handler method and stepped through my code. On the first click, none of the event handlers are triggered. On the second click, they are triggered. Any ideas? Example of Button Definition Button btn = new Button(); btn.Text = "Click Me Locked Screen"; bth.Click += new EventHandler(Btn_Click); Example of Event Handler Method Definition void Btn_Click(object sender, EventArgs e) { // Do Something }

• SpringFramework3.0: How to create interceptors that only apply to requests that map to certain contr

  - by Fusion2004

  In it's simplest form, I want an interceptor that checks session data to see if a user is logged in, and if not redirects them to the login page. Obviously, I wouldn't want this interceptor to be used on say the welcome page or the login page itself. I've seen a design that uses a listing of every url to one of two interceptors, one doing nothing and the other being the actual interceptor you want implemented, but this design seems very clunky and limits the ease of extensibility of the application. It makes sense to me that there should be an annotation-based way of using interceptors, but this doesn't seem to exist. My friend has the idea of actually modifying the handler class so that during each request it checks the Controller it is mapping the request to for a new annotation we would create (ex @Interceptor("loginInterceptor") ). A major point of my thinking is the extensibility, because I'd like to later implement similar interceptors for role-based authentication and/or administration authentication. Does it sound like my friend's approach would work for this? Or what is a proper way of going about doing this?

• multiple models in Rails with a shared interface

  - by dfondente

  I'm not sure of the best structure for a particular situation in Rails. We have several types of workshops. The administration of the workshops is the same regardless of workshop type, so the data for the workshops is in a single model. We collect feedback from participants about the workshops, and the questionnaire is different for each type of workshop. I want to access the feedback about the workshop from the workshop model, but the class of the associated model will depend on the type of workshop. If I was doing this in something other than Rails, I would set up an abstract class for WorkshopFeedback, and then have subclasses for each type of workshop: WorkshopFeedbackOne, WorkshopFeedbackTwo, WorkshopFeedbackThree. I'm unsure how to best handle this with Rails. I currently have: class Workshop < ActiveRecord::Base has_many :workshop_feedbacks end class Feedback < ActiveRecord::Base belongs_to :workshop has_many :feedback_ones has_many :feedback_twos has_many :feedback_threes end class FeedbackOne < ActiveRecord::Base belongs_to :feedback end class FeedbackTwo < ActiveRecord::Base belongs_to :feedback end class FeedbackThree < ActiveRecord::Base belongs_to :feedback end This doesn't seem like to the cleanest way to access the feedback from the workshop model, as accessing the correct feedback will require logic investigating the Workshop type and then choosing, for instance, @workshop.feedback.feedback_one. Is there a better way to handle this situation? Would it be better to use a polymorphic association for feedback? Or maybe using a Module or Mixin for the shared Feedback interface? Note: I am avoiding using Single Table Inheritance here because the FeedbackOne, FeedbackTwo, FeedbackThree models do not share much common data, so I would end up with a large sparsely populated table with STI.

• Is there an efficient algorithm to distribute resources in a way that both avoids conflict and allows bias?

  - by Steve V.

  Background (Skip this if you only care about the algorithm) At the university where I work, one of the biggest hassles in our department is classroom scheduling. For illustration purposes and to lay out the scope of the problem, here's how we do scheduling now: Professors give us a list of the classes they're teaching with the time slots they'd prefer to teach, ranked in order of priority (most desired to least desired). Administration gives us a list of the rooms we may assign along with the times those rooms are available for our department's use. We start assigning professors to rooms trying (at first) to take into account the preferences of the various professors. Inevitably, conflicts arise, professors start asking for changes, and the plan falls to pieces somewhere around professor number 30, at which point we start assigning rooms basically wherever we can fit them in, crumpled pieces of paper are everywhere, and nobody's happy. (If you've ever wondered why your class was at 9.30 in the morning on Thursday but 4 pm every other day, now you know) I have been asked to quietly investigate whether software could do this more optimally. The Actual Question Is there an algorithm to efficiently schedule a set of resources such that the following criteria are met: The algorithm must never assign two professors to the same room at the same time. The task is not complete until every professor has been assigned a room / time. The algorithm need not worry about having too many professors for the amount of time slots available. (We're not that well funded.) As much as is possible the algorithm should respect the scheduling preferences of the individual professors. I feel like I can't be the first one to ask this. Is there a efficient algorithm for this, or is this the sort of problem that can only be brute-forced?

• Cookies not working for password-protected Pages on WordPress

  - by KaOSoFt

  Initially I had the issue reported in this question. Now, what I noticed is that there are some browsers that accept the password, and there are some which don't. Difference? For some reason the cookie is generated when I log in into the Administration module, but it isn't when I write down the password to access the page, forcing it to simply reload. I can see the cookie created for the log-in, but I can see none for the password-protected Page. These happens on Internet Explorer, both version 7 and 8; only on some machines, though, but most of them fail this. I already tried white-listing the URL, and even letting it accept ALL cookies, to no avail. What may be the cause? If perhaps it's got something to do with question above, please help me! Thanks in advance. PS: If you know of another, cookie-free method to make a simple authentication, please link me to it. Thanks. Oh, and by the way, this is inside an Intranet with static, class C IPs.

• Need help with transferring data between MySQL db's using PHP

  - by JM4

  In one of the sites I manage, the client has decided to take on ACH/Bank Account administration where it was previously outsourced. As a result, the information submitted in our online form which used to simply store in a single database for processing now must sit in 'limbo' until the funds used for payment have been verified. My original plan is as follows: At the end of an enrollment, all form data is collected and stored in a single MySQL database. Our internal administrator will receive an email notification reminding him enrollments have taken place. He will process the ACH information collected and wait the 3-4 business days needed for payment to clear. Once the payment information has been returned as Good (haven't considered what I will do with the 'bad' yet), the administrator can log into a secure portal which allows him to click a button to 'process' the full information once compared and verified. the process is simplified as: Enrollment complete: data stored in DB 'A' Funds verified and link clicked: data from 'A' is copied to DB 'B' and 'A' is deleted. I have run similar processes with CSV output before and simply used //transfers old data to archive $transfer = mysql_query('INSERT INTO '.$archive.' SELECT * FROM '.$table) or die(mysql_error()); //empties existing table $query = mysql_query('TRUNCATE TABLE '.$table) or die(mysql_error()); but in those cases, ALL data returned was copied and deleted. I only want to copy and delete a single record. Any idea how to accomplish this?

• PHP suddenly failed after IIS update

  - by James Hay

  All my application pools were stopped this morning after I got to work. I can restart them, but when I try to load the website the app pool crashes again. Update: I've looked in the GAC as the error below suggests and it seems that the file is not there. How do I get it back? Update 2: I found a further error in the event log saying The Module name FastCgiModule path C:\WINDOWS\System32\inetsrv\iisfcgi.dll returned an error from registration. The data is the error. So following the information from here http://forums.iis.net/t/1153937.aspx I removed CGI and my sites are working again. This has fixed the initial problem, but now I don't have FastCGI so I'm fairly sure that PHP will no longer be working (I don't have any PHP at the moment to test).

• Pros/Cons of switching from Exchange to GMail

  - by Brent

  We are a medium-large non-profit company, with around 1000 staff and volunteers, and have been using MS Exchange (currently 2003) for our mail system for years. I recently attended a Google conference where they were positing that "Cloud computing is the way of the future", and encouraging us to switch from doing our own email with Exchange, to using GMail and Google Apps for everything. Additionally, one of our departments has been pushing from inside to do this transition within their own department, if not throughout the entire organization. I can definitely see some benefits - such as: Archive space - we never seem to have the space our users want, and of course, the more we get, the more we have to back up OS Agnostic - Exchange is definitely built for windows, and with mac and linux users on the rise, these users increasingly demand better tools / support. Google offers this. Better archiving - potential of e-discovery, that doesn't exist in a practical way with our current setup. Switching would relieve us of a fair bit of server administration, give more options to our end users, and free up the server resources we are now using for Exchange. Our IT department wants to be perceived as providing up-to-date solutions to technical problems, and this change would definitely provide such an image. Google's infrastructure is obviously much more robust than ours, and they employ some of the world's best security and network experts. However, there are also some serious drawbacks: We would be essentially outsourcing one of our mission-critical systems to a 3rd party The switch would inevitably involve Google Apps and perhaps more as well. That means we would have a-lot more at the mercy of a single (potentially weak) password. (is there a way to make this more secure using a password plus physical key of some sort??) Our data would not remain under our roof - or even in our country (Canada). This obviously has plusses on the Disaster Recovery side, but I think there are potential negatives on the legal side. I can't imagine that somebody as large as Google would be as responsive as we would want with regard to non-critical issues such as tracing missing emails, etc. (not sure how much access we would have to basic mail logs - for instance) Can anyone help me evaluate this decision? What issues am I overlooking? What experiences have you had with this transition (or the opposite - gmail to Exchange) Can you add to the points I have already outlined?

• Using WSUS Admin Console from outside domain

  - by Nick

  Environment: I have a workstation on our primary domain. We have a primary WSUS Server that is the upstream server of 8 different testing domains. The Primary WSUS server is not part of any domain. Routing is configured between my workstation and the Primary WSUS server. I can RDP to the Primary WSUS sever without any problem. The router is configured to forward any any between my workstation and the Primary WSUS server. This WSUS server cannot be part of a domain due to external requirements (I can't change them) on the lab I work in. The version of WSUS is WSUS 3.0 SP 2 What I want to do: I need to connect to the WSUS server with the WSUS Admin console from my local workstation. The end goal is to connect via Powershell and manage with that. I also need to take what I do here and port it to the 8 test domains so I can manage those WSUS servers. The routing is all in place so I can talk to the servers, it's just connecting to the WSUS console that is causing problems. The problem: I cannot get my workstation to connect to the WSUS Console. I get one of the following errors depending on the setup. 1st error: Cannot connect to 'WSUS'. You do not have the permissions required to access this WSUS server. To connect to the server you must be a member of the WSUS Administrators or WSUS Reporters security groups I also get the warning 7012 from the event log that says the same thing. 2nd error: Cannot connect to 'WSUS'. The server may be using another port or different Secure Sockets Layer setting. What I have tried: So far I have configured IIS for Anonymous Authentication on both the WSUS Administration and ApiRemoting30 using an account will call WSUS_User. With this in place, I get the 1st error. When I do this though, the local WSUS Console cannot be used either. Reverting back to only Windows Authentication allows the local console to work, but the remote console now give the 2nd error. I have confirmed the port, and that there is no SSL in use (which is a policy that is pushed from above, that I cannot effect). I have placed WSUS_User in the groups mentioned above, but it still does not connect. I made sure WSUS_User has full access on C:\Program Files\Update Services and C:\Program Files\Update Services\WebServices I am not very familiar with the workings of WSUS or IIS, and have gone as far as I can figure out on my own. Googling these errors all take me to the same steps about Anonymous Authentication and configuring permissions on folders. Note: I have cross-posted this to StackOverflow as well.

• IIS can't load Oracle.Web assembly (for ASP.NET membership provider)

  - by Konamiman

  I am trying to configure an IIS web site to use an Oracle database for ASP.NET membership, but I can't get it to work. IIS doesn't seem to be able to load the assembly containing the Oracle membership provider. That's what I have so far: An Oracle 10g database online and with all the tables for ASP.NET membership created. Windows 2008 R2 Standard with the web server role installed, including support for ASP.NET. Oracle 11g Release 2 ODAC 11.2.0.1.2 installed. The installed components are: Oracle data provider for .NET, Oracle providers for ASP.NET, Oracle instant client. The default web site on IIS (I am using that for testing) has the following web.config file: <?xml version="1.0" encoding="UTF-8"?> <configuration> <system.web> <membership defaultProvider="OracleMembershipProvider"> <providers> <remove name="SqlMembershipProvider" /> <add name="OracleMembershipProvider" type="Oracle.Web.Security.OracleMembershipProvider, Oracle.Web, Version=2.112.1.2, Culture=neutral, PublicKeyToken=89b483f429c47342" connectionStringName="OracleServer" /> </providers> </membership> </system.web> </configuration> (Additional attributes on the "add" element omitted for brevity. Also, the connection string is defined for the whole server.) The Oracle.Web.dll file is on the GAC. That's the relevant part of the C:\Windows\Assembly folder: The web site application pool is configured for .NET 2.0, and has 32-bit applications enabled. I have allowed untrusted providers in the IIS' administration.config file (just for the sake of testing, I'll explicitly add the assembly to the trusted providers list later). With all of this setup in place, when I click on the ".NET Users" icon on the IIS manager, I get a warning about the provider having too much privileges, and when I accept I get the following message: There was an error while performing this operation. Details: Could not load file or assembly 'Oracle.Web, Version=2.112.1.2, Culture=neutral, PublicKeyToken=89b483f429c47342' or one of its dependencies. The system cannot find the file specified. So, what am I missing? How can I get the Oracle membership provider to work? Thank you! UPDATE: It seems that the problem is not with IIS itself, but with the IIS administrator only. When using the web site configuration tool provided by Visual Studio, everything works fine.

• Splitting an internet connection between multiple separate subnetworks

  - by pythonian4000

  Problem I have an internet connection that I want to split between four separate networks. My requirements are: I need to be able to monitor the amount of bandwidth and data being used by each network, and notify or control as necessary. The four networks should only be able to connect to the internet, not each other. My parents need to be able to operate it, so it needs a simple, preferably Windows-based GUI. Progress so far Server I have a mini-ITX server with six Gigabit ethernet ports - one for the ethernet internet connection, one for each of the four networks, and one for remote access to the server for administration. Bandwidth control I spent a long time researching solutions here. The majority of the control systems/software I found could control bandwidth usage via QOS, but could not monitor or control the amount of data being used. Eventually I found the SoftPerfect Bandwidth Manager, which has everything I need in terms of monitoring and control - per-interface quota management, usage statistics, a web interface for checking usage, and email notifications when quotas are exceeded. It is also Windows-based and has a simple GUI. Internet sharing This is where I am having issues. I am currently using Windows XP Pro SP2 for the server (yes, I know this is far from ideal, but it's the only spare Windows OS I currently have). I can't use the built-in Internet Connection Sharing for several reasons: The upstream internet router has an IP of 192.168.0.1 which ICS clashes with, and I cannot change the router settings. ICS can only share an internet connection with a single interface, but I have four. I have tried bridging the four network cards, but then the Bandwidth Manager cannot see the four individual interfaces - it only sees the bridge. I have tried setting up Dual DHCP DNS server (and am having issues getting DHCP offers to be received by clients), but that would still require gateway software of some sort, which I have been unable to find. My current attempt is to use OpenVPN, with a server for the internet NIC and a separate client for each of the four networks. My thought is that I could bridge the OpenVPN TAP devices to each NIC, meaning that the Bandwidth Manager would control traffic from the bridge instead of the interface. I have not made much progress here though - I've never used OpenVPN before. Questions Is there a Windows software package that does everything I need? (Unlikely, I know) Is there a Windows software package that will share internet between multiple NICs without bridging? Are either of my about attempts feasible? Would it help to have a newer/server version of Windows? Is there a non-Windows alternative that is easy to use?

• How Do I Restrict Repository Access via WebSVN?

  - by kaybenleroll

  I have multiple subversion repositories which are served up through Apache 2.2 and WebDAV. They are all located in a central place, and I used this debian-administration.org article as the basis (I dropped the use of the database authentication for a simple htpasswd file though). Since then, I have also started using WebSVN. My issue is that not all users on the system should be able to access the different repositories, and the default setup of WebSVN is to allow anyone who can authenticate. According to the WebSVN documentation, the best way around this is to use subversion's path access system, so I looked to create this, using the AuthzSVNAccessFile directive. When I do this though, I keep getting "403 Forbidden" messages. My files look like the following: I have default policy settings in a file: <Location /svn/> DAV svn SVNParentPath /var/lib/svn/repository Order deny,allow Deny from all </Location> Each repository gets a policy file like below: <Location /svn/sysadmin/> Include /var/lib/svn/conf/default_auth.conf AuthName "Repository for sysadmin" require user joebloggs jimsmith mickmurphy </Location> The default_auth.conf file contains this: SVNParentPath /var/lib/svn/repository AuthType basic AuthUserFile /var/lib/svn/conf/.dav_svn.passwd AuthzSVNAccessFile /var/lib/svn/conf/svnaccess.conf I am not fully sure why I need the second SVNParentPath in default_auth.conf, but I just added that today as I was getting error messages as a result of adding the AuthzSVNAccessFile directive. With a totally permissive access file [/] joebloggs = rw the system worked fine (and was essentially unchanged), but as I soon as I start trying to add any kind of restrictions such as [sysadmin:/] joebloggs = rw instead, I get the 'Permission denied' errors again. The log file entries are: [Thu May 28 10:40:17 2009] [error] [client 89.100.219.180] Access denied: 'joebloggs' GET websvn:/ [Thu May 28 10:40:20 2009] [error] [client 89.100.219.180] Access denied: 'joebloggs' GET svn:/sysadmin What do I need to do to get this to work? Have configured apache wrong, or is my understanding of the svnaccess.conf file incorrect? If I am going about this the wrong way, I have no particular attachment to my overall approach, so feel free to offer alternatives as well. UPDATE (20090528-1600): I attempted to implement this answer, but I still cannot get it to work properly. I know most of the configuration is correct, as I have added [/] joebloggs = rw at the start and 'joebloggs' then has all the correct access. When I try to go repository-specific though, doing something like [/] joebloggs = rw [sysadmin:/] mickmurphy = rw then I got a permission denied error for mickmurphy (joebloggs still works), with an error similar to what I already had previously [Thu May 28 10:40:20 2009] [error] [client 89.100.219.180] Access denied: 'mickmurphy' GET svn:/sysadmin Also, I forgot to explain previously that all my repositories are underneath /var/lib/svn/repository UPDATE (20090529-1245): Still no luck getting this to work, but all the signs seem to be pointing to the issue being with path-access control in subversion not working properly. My assumption is that I have not conf

• Slow Windows Explorer on Windows 7

  - by MadBoy

  I have Laptop with i7 (4 cores), 8GB ram and SSD OCZ Vertex 3 MaxIOPS which in testing that I did just now does 400mb/s+ read/write. However the responsiveness of Windows Explorer is far from being perfect. Opening up Computer, Documents, going into folders is very slow (1-5seconds). I don't have any viruses or spyware and I have tried changing properties to optimize view for General Items. I tried disabling Search Indexer but it made search in Outlook 2010 crawl and didn't bring any other effect. Even double clicking on file takes some time to open things up (like clicking a Word document). I don't have any drives mapped, my computer is not joined to domain. I have multiple VPN connections that I connect to but they all have disabled default gateways. I tried using CC Cleaner or some Windows 7 Tweaks app to disable some things. I am power user using Visual Studio, Tortoise SVN and other developer/administration apps. Any non obvious ideas? Edit: So I've been trying to pinpoint where the issue comes from and it seems that straight after reboot Windows Explorer opens very fast, when I load 3-4 programs (Royal TS, Visual Studio, Outlook) it's noticeably slower and the more programs I have it gets worse. After I start closing programs it starts working better and if I leave 2 open it's fast again. I tried doing some research with DiskMon and other programs from sysinternals but couldn't find anything suspicious. Below are stats during normal usage with a lots of programs open: - Ram usage with a lot of programs open and no swap file (i disabled it for testing): 6.95GB - CPU usage: 15%, none of the cores takes more then 50% (I have VS 2010 open x 4) HD Tune Pro: OCZ-VERTEX3 MI Benchmark Test capacity: full Read transfer rate Transfer Rate Minimum : 363.9 MB/s Transfer Rate Maximum : 505.5 MB/s Transfer Rate Average : Access Time : Burst Rate : CPU Usage : HD Tune Pro: OCZ-VERTEX3 MI File Benchmark Drive C: Transfer rate test File Size: 500 MB Sequential read 484102 KB/s Sequential write 444714 KB/s Random read 7779 IOPS Random write 16888 IOPS Random read (queue depth = 32) 73007 IOPS Random write (queue depth = 32) 69790 IOPS HD Tune Pro: OCZ-VERTEX3 MI Random Access Test capacity: full Read test Transfer size operations / sec avg. access time max. access time avg. speed 512 bytes 3260 IOPS 0.306 ms 2.106 ms 1.592 MB/s 4 KB 4161 IOPS 0.240 ms 2.006 ms 16.256 MB/s 64 KB 2382 IOPS 0.419 ms 2.367 ms 148.934 MB/s 1 MB 449 IOPS 2.225 ms 4.197 ms 449.407 MB/s Random 809 IOPS 1.235 ms 6.551 ms 410.527 MB/s HD Tune Pro: OCZ-VERTEX3 MI Extra Tests Test capacity: full Random seek 3975 IOPS 0.252 ms 1.941 MB/s Random seek 4 KB 4245 IOPS 0.236 ms 16.583 MB/s Butterfly seek 4086 IOPS 0.245 ms 1.995 MB/s Random seek / size 64 KB 3812 IOPS 0.262 ms 58.606 MB/s Random seek / size 8 MB 120 IOPS 8.348 ms 485.737 MB/s Sequential outer 4524 IOPS 0.221 ms 282.721 MB/s Sequential middle 4429 IOPS 0.226 ms 276.818 MB/s Sequential inner 5504 IOPS 0.182 ms 344.000 MB/s Burst rate 4472 IOPS 0.224 ms 279.475 MB/s

• XP OEM licensing when reinstalling Windows XP

  - by mindas

  My wife has managed to buy a Dell laptop she was using at her ex-employer that just went bust. The problem with it is the OS (Windows XP) which takes ages to boot and is generally disproportionally slow to the hardware of the machine. So my aim is to sacrifice a day and reinstall it. The problem I am slightly worried about is the licensing/registration/activation hell. Apart from the sticker (with WinXP license key), the laptop has no other paperwork proving this license is legitimate. I believe this was originally an OEM license. Unfortunately, I don't have the the installation CD. This computer also has MS Office installed (which I would like to retain) but it none of MS Office apps would launch due to some obscure error complaining about lack of free disk space (which computer has plenty of). I have absolutely no clue what kind of license this MS Office was. And because the company has gone into the administration, there is no way of getting this information nor installable media. I believe that by buying the hardware I have also acquired the software which I can use as I see fit. Correct me if I'm wrong. Above said, my question would be: What is the easiest way of reinstalling the XP? By easiest I mean avoiding spending my time to prove Microsoft support I've got the right to use the software (insert your computer says noooo joke here) but still being able to get to fresh virgin activated legal state of the XP. I used to work as a sysadmin many years ago so I am not afraid of any technical difficulties. The same question applies to MS Office. I imagine the process would consist of backing up all the data, pulling some bits from the registry and using that on the fresh install. As for reinstall I'd expect to use some sort of OEM Windows repair CD from Dell, right? Are those freely available? My other box (HP) has such a thing and it can't be used on any other brand. I'm sure somebody had to go through this licensing hell and could share his/her tips. Thanks in advance.

• How can I prevent an unintentional DDOS running ColdFusion 8 with IIS 6?

  - by Eric Belair

  We had an interesting outage today on one of our client's websites. Out of nowhere, the website was inaccessible. The website runs by itself on a dedicated physical Windows 2000 server (probably overkill, I know, but that's a discussion for a different day). After restarting IIS and ColdFusion Application Service, the problem came back several times. My initial thought was that it was a DNS issue, which happens occasionally - the last time it happened was after Hurricane Sandy when we our ISP was out, and we had to make some network config changes. But, it was not a DNS issue. My second thought was that it was a DDOS attack, but, there's very little reason anyone would want to take this site down. When we called our ISP, the operator on the other end noted that traffic was spiking significantly. As it turned out, the client had unintentionally caused a DDOS on the website, after they FTPed a very large video file, and then mass emailed a link to it. Hundreds of people clicked the link and brought the site to its knees. I am primarily a Website Programmer, but I often have to contribute to server administration at times. Sadly, I'm the resident ColdFusion and IIS expert, but I don't have a lot of experience with this issue. What are some basic steps that I can take to prevent this from happening in the future, since we cannot always control what files the client posts to the website. Here are some ideas I had, but I'm unsure of the impact: Limit the number of connections in IIS. Put media files on a separate server (like an Amazon site, etc.). File requests of this type currently behind a server-script (i.e. /www.site.com/viewFile.cfm?fileId=1424545, where the fileId references a file off the webroot) that logs requests, and pushes the file to the browser using CFCONTENT. I could edit this script to reject requests when they exceed a certain amount in a given time-frame (i.e. a 5MB can be accessed globally 10 times in an hour). This may cause some users frustration, but, if hundreds of users are attempting to view the file, the site is going to crash anyways, as it did today, which is way more frustrating, since there is no "pretty" message explaining why they can't get to the file. I'm open to any suggestions, as I'm continuing my research to report to the CTO with the best options, so that we can put a solution into effect. Thank you.

• Why can't I use SSL certs imported via Server Admin in a custom Apache install?

  - by morgant

  I've got a couple of Mac OS X 10.6.8 Server web servers that run a custom AMP255 (Apache 2.x, MySQL 5.x, and PHP 5.x) stack installed using MacPorts. We've got a lot of Mac OS X Server servers and generally install SSL certs via Server Admin and they "just work" in the built-in services, however, these web servers have always had SSL certs installed in a non-standard location and used only for Apache. Long story short, we're trying to standardize this part of our administration and install certs via Server Admin, but have run into the following issue: when the certs are installed via Server Admin and referenced in our Apache conf files, Apache then prompts for a password upon trying to start. It does not seem to be any password we know, certainly not the admin or keychain passwords! We've added the _www user to the certusers (mainly just to ensure they have the proper access to the private key in /etc/certificates/). So, with the custom installed certs we have the following files (basically just pasted in from the company we purchase our certs from): -rw-r--r-- 1 root admin 1395 Apr 10 11:22 *.domain.tld.ca -rw-r--r-- 1 root admin 1656 Apr 10 11:21 *.domain.tld.cert -rw-r--r-- 1 root admin 1680 Apr 10 11:22 *.domain.tld.key And the following in the VirtualHost in /opt/local/apache2/conf/extra/httpd-ssl.conf: SSLCertificateFile /path/to/certs/*.domain.tld.cert SSLCertificateKeyFile /path/to/certs/*.domain.tld.key SSLCACertificateFile /path/to/certs/*.domain.tld.ca This setup functions normally. If we use the certs installed via Server Admin, which both Server Admin & Keychain Assistant show as valid, they're installed in /etc/certificates/ as follows: -rw-r--r-- 1 root wheel 1655 Apr 9 13:44 *.domain.tld.SOMELONGHASH.cert.pem -rw-r--r-- 1 root wheel 4266 Apr 9 13:44 *.domain.tld.SOMELONGHASH.chain.pem -rw-r----- 1 root certusers 3406 Apr 9 13:44 *.domain.tld.SOMELONGHASH.concat.pem -rw-r----- 1 root certusers 1751 Apr 9 13:44 *.domain.tld.SOMELONGHASH.key.pem And if we replace the aforementioned lines in our httpd-ssl.conf with the following: SSLCertificateFile /etc/certificates/*.domain.tld.SOMELONGHASH.cert.pem SSLCertificateKeyFile /etc/certificates/*.domain.tld.SOMELONGHASH.key.pem SSLCertificateChainFile /etc/certificates/*.domain.tld.SOMELONGHASH.chain.pem This prompts for the unknown password. I have also tried httpd-ssl.conf configured as follows: SSLCertificateFile /etc/certificates/*.domain.tld.SOMELONGHASH.cert.pem SSLCertificateKeyFile /etc/certificates/*.domain.tld.SOMELONGHASH.key.pem SSLCertificateChainFile /etc/certificates/*.domain.tld.SOMELONGHASH.concat.pem And as: SSLCertificateFile /etc/certificates/*.domain.tld.SOMELONGHASH.cert.pem SSLCertificateKeyFile /etc/certificates/*.domain.tld.SOMELONGHASH.key.pem SSLCACertificateFile /etc/certificates/*.domain.tld.SOMELONGHASH.chain.pem We've verified that the certificate is configured to allow all applications access it (in Keychain Assistant). A diff of the /etc/certificates/*.domain.tld.SOMELONGHASH.key.pem & *.domain.tld.key files shows the former is encrypted and the latter is not, so we're assuming that Server Admin/Keychain Assistant is encrypting them for some reason. I know I can create an unencrypted key file as follows: sudo openssl rsa -in /etc/certificates/*.domain.tld.SOMELONGHASH.key.pem -out /etc/certificates/*.domain.tld.SOMELONGHASH.key.no_password.pem But, I can't do that without entering the password. I thought maybe I could export an unencrypted copy of the key from Keychain Admin, but I'm not seeing such an option (not to mention that the .pem options are greyed out in all export options). Any assistance would be greatly appreciated.
