  • How do I secure a .NET Web Service for use by an iPhone application?

    - by David A Gibson
    Hello, The title says it all, I have a Web Service written in .NET that provides data for an iPhone application. It will also allow the application make a "reservation." Currently it's all internal to the corporate network but obviously when the iPhone application is published I will need ensure the Web Service is available externally. How would I go about securing the Web Service? There are two aspects I'm looking into: Authentication for accessing the web service Protection for the data being transferred I'm no so bothered about the data being passed back and forth as it will be viewable in the application anyway (which will be free). The key issue for me is preventing users from accessing the Web Service and making reservations themselves. At the moment I am considering encrypting any strings in the XML data passed back and forth so only the client can effectively use the web service sidestepping the need for authentication and providing protection for the data. This is the only model I have seen but I think the overheads on the iPhone and even for the web service make for a poor user experience. Any solutions at all would be most welcome? Thanks

  • [solved] IE6 PNG-transparency CSS hack not working

    - by John
    I looked around and decided to use a CSS approach rather than rely on JS... I figure the kind of corporate users stuck with IE6 might also have JS disabled by IT departments. So In my HTML I have: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <meta http-equiv="Content-Type" content="text/html;charset=utf-8" /> <title>My Page</title> <link rel="stylesheet" type="text/css" href="default.css" /> <!--[if IE 6]><link rel="stylesheet" type="text/css" href="ie6.css"><![endif]--> </head> <body> <img src="media/logo.png"/> </body> Then my ie6.css consists simply of: img { filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(...); } However none of this makes the slightest difference, no transparency. I commented out all the rest of the page so it is literally that one and still no luck. I removed the default.css stylesheet and still no difference. EDIT: I now got it working, using the .htc method, loading that file in a conditional IE6 test block. It turned out the problem I was having was that Windows 7 had 'locked' the file (I don't even know what this means) and this blocked IE from loading/using it.

  • Just 2 free months 2 learn or improve my skills

    - by microspino
    On the 30 of June I will leave my every day work to start as freelance developer. I'd like to set a period of 2 months apart to improve my dev skills. At work I code in C# and during my spare time I enjoyed building Ruby on Rails web applications and creating some Arduino prototypes. I'm something more than junior but I don't feel really a senior developer because I never had a big corporate project built and designed by me with help of other juniors (although I don't think this is really a good definiton of a "senior", It helps describing my feelings). Using a scale from 0 (ignorant) to 10 (proficient like a "samurai") the list below describes my skills that I would like to improve with just 2 months. I've already bought some nice and updated books on all the subjects hereunder: The order doesn't matter C = 1 C# & .Net = 6 Arduino & Processing = 2 Ruby = 5 Rails = 5 HTML/XHTML/CSS = 9 Javascript = 6 Objective-C/iPhone dev = 2 Python = 4 Django = 4 Desing Patterns = 3 Algorythms = 3 Git = 5 I haven't included SQL or Databases in general nor Networking because I spent 10 years working in the past with them and I feel pretty solid for now. As an aside, I've made up some interest in Redis, Node.js, HTML5 reading about them on the web. After two months, since I have to pay my bills, I could go searching for some new job. If learning and developing were really good maybe I could also invest on something I gave birth during them. Can You give me some piece of advice on which you think It's better to improve or develop a learning project on (something like a "summer of code" thing)? The all point Is to see my weeknesses and work on them.

  • Why is UseCompatibleTextRendering needed here?

    - by HotOil
    Hi, I think I'm missing something fundamental. Please tell me what it is, if you can. I have developed a little C++ WinForms app using VS2008. So it is built using .NET 3.5 SP1. My development box is Win7, if that matters. The default value of UseCompatibleTextRendering property in WinForms controls is false in this version of VStudio. And this should not matter to me, I don't think. I don't have any custom-drawn text or controls. The app looks good running on my Win7 box. If I package it up (dragging along .NET 3.5) and install it on one of our WinXP desktops, the buttons and labels don't look good; the text is chopped off in them. If I set UseCompatibleTextRendering to true and then run it on the XP boxes, the text fits into the buttons and labels. My question is: Why? The installation puts .Net 3.5 on the XP boxes, so the app should be able to find and use the right version of WinForms, right? I should note that before I put my app + .NET 3.5 on these boxes, they have no .NET at all. They do not get automatic Microsoft updates; our IT guy gates the patches and upgrades. [ This sort of thing has happened before with apps I create.. they look/work great on the Engineering machines, because we maintain those and they mostly have up-to-date stuff. When they are run on the corporate boxes, they usually don't run and need the VCredist installed. ] Back to the question at hand: The text looks better with the UseCompatibleTextRendering set to false, so I'd rather keep it that way, if I can. I'd like to understand what might be missing on those XP boxes that is making the text not fit. Thanks S

  • Is there anything on a local network or desktop environment that could effect JScript execution?

    - by uku
    I know this sounds odd. The JS on my project functions perfectly, except when the web site is accessed using computers at one specific company. To make things even more difficult, the JS fails only about 50% of the time when run from that company. The JS failure occurs with FireFox, Chrome, and IE. I have tested this myself using FF and Chrome on a thumb drive. The browsers on my thumb always display my project site perfectly, except when run from a computer on said company's network where they fail at the same rate as the installed browsers. My JS is using jQuery and making some Ajax calls. The Ajax calls are where the failure is occurring. To diagnose the problem I created a logging function for my Ajax calls and recorded success and failure. Over a one month period, there were only a handful of failures (about 1%) from all access points other than this company. Oddly enough, the Ajax calls in the logging function are not failing. There is nothing exotic there - Just Win XP SP3. I have never noticed any other unusual behavior from their network. The company is a division of a mega ISP and is on their corporate network. Any other suggestions for troubleshooting would be welcome.

  • ASP.NET MVC 2: HtmlHelpers, foreach?

    - by dcolumbus
    This one is new to me... I'm bringing in a Model that represents a list of items. Some items should be rendered as a number of checkboxes and radios. Others will be rendered in a list. Now I know how to foreach the items and spit them out manually... but I'd like to be able to check them against the Model that I have, making sure that at least one optios is selected/chosen. And obviously display the associated validation errors. This is how I am displaying the checkbox items manually: <ul> <% foreach (Corporate.Entities.DesignLayout.Tag tag in Model.DesignOptions.Items) { %> <li><input type="checkbox" /><%: tag.TagName %></li> <% } %> </ul> Two questions arise: 1) How do I check that list of checkboxes against my model? 2) How would I render the tag items with an HtmlHelper SelectList? Example: <%: Html.ListBoxFor(m=>m.DesignOptions, [don't know what I should put here]) %>

  • how to seamlessly integrate subversion and git?

    - by mattv
    I'm looking for tips on how to seamlessly integrate subversion and git, for deploying web sites by a small team of web developers. We each have our own development versions of our sites on our local machines. We also have dev, staging, and live servers. As our team has grown, we haven't updated our revision control and deployment strategies accordingly. We had all been checking into the trunk of a shared Subversion repository. Both the dev & staging servers ran from a checkout of the trunk, so updating them involved running "svn update" while the live server ran as an export from trunk which required an "svn export" to get the latest code. In either case, we would often update just certain files by updating or exporting just those files or directories. That worked okay when there was just one or two developers. However, a big downside was that we couldn't point to an individual tag that represented what was currently on live at any given time. In keeping with corporate policy, we'd like to continue to use Subversion to store what we're now calling our "production branch," which will be what goes onto staging and live. However, we would like to use Git on our local and development sites. We especially like the idea of easier merges and being able to "cherry pick" updates that need to go live. We had initially planned on using git-svn, but it doesn't seem to work well in a shared environment such as our dev or staging servers. Anyone else doing something like this? What's the best way to make it work? Or are we making it more difficult than it should be?

  • Is it a wise decision to go from dev to third line/Tier 3 dev support?

    - by dotnetdev
    Hi, I am an experienced, mid-level developer. However, I recently spotted a job for a company which is small but has a lot of emphasis on training(beyond the basic technical training, but also mentoring, leadership training, etc). The role is 3rd line so still very technical. It's in app support so it's post implementation development rather than pure out-and-out development like I do now (or don't, as the senior devs do all of the interesting work). However, and this is the question - is this sort of career move common? Also, wouldn't a tech support role be a big shock to the system because I've never dealt with customers? I therefore think it's a bad move? Working in dev, I am used to the lack of customer contact and it is all filtered through by my manager. But in tech support, contacting customers/rude customers could be scary. I don't mind fixing other people's mistakes (better than me making mistakes!) and doing post-implementation dev for production systems (will give me a lot of discipline), and I do get bored sitting in the same place looking/talking to the same people in suits (I work in a corporate environment). The company puts A LOT of emphasis on training and prospects, which I don't get in the current (big) company I work at. Any advice on how to handle tech support is appreciated! Thanks

  • Planning a programming project by example (C# or C++)

    - by Lunan
    I am in the last year of undergraduate degree and i am stumped by the lack of example in c++ and c# large project in my university. All the mini project and assignment are based on text based database, which is so inefficient, and console display and command, which is frustrating. I want to develop a complete prototype of corporate software which deals in Inventory, Sales, Marketing, etc. Everything you would usually find in SAP. I am grateful if any of you could direct me to a books or article or sample program. Some of the question are : How to plan for this kind of programming? should i use the concept of 1 object(such as inventory) have its own process and program and have an integrator sit for all the program, or should i integrate it in 1 big program? How to build and address a database? i have little bit knowledge in database and i know SQL but i never address database in a program before. Database are table, and how do you suppose to represent a table in a OOP way? For development type, which is better PHP and C++ or C# and ASP.NET? I am planning to use Web Interface to set form and information, but using a background program to handle the compute. .NET is very much integrated and coding should be much faster, but i really wonder about performance if compared to PHP and C++ package thank you for the info

  • What is the best way to implement a callback scenario using WCF and ASP.NET MVC?

    - by Mark Struzinski
    I am new to WCF. I just finished reading Learning WCF and I think I've got a pretty good grasp of the fundamentals. I am adding functionality to a line of business app that runs on ASP.NET MVC entirely inside the corporate LAN. I am calling into a service that will also send me events as they occur (and not as responses to service calls). These events can occur at any point during the user's session. I have the service written, and it is able to pick up these events. What would be the best way to deliver these events to the user? My initial thought is to run the WCF service in duplex mode over net TCP and implement the events as callbacks. Using this scenario, the best way I can think up to deliver the events to the user is a dictionary object stored in the session. The dictionary would be populated by the callbacks and polled on a set frequency for delivery via AJAX calls. Has anyone dealt with this scenario? Is there a more efficient way to implement this?

  • What are the best websites/web applications for specific languages?

    - by JM4
    Browsing around Stackoverflow, I get overwhelmed with the number of "Why should I learn Python/Ruby/PHP/.Net/jQuery..." and the list goes on. Most answers, although good, are usually battles from language A programmer to language B programmer detailing why one piece sucks more than another. People can discuss the theoretical benefits of one over another but in the end, money/glitz talks and the rest walks. I am more interested in the potential opportunity that can come from one language or another over others. A little background, I am a project manager turned novice 'programmer' out of corporate necessity within the small company I currently work with so I have both relatively no set preference or experience, more out of curiosity. While I realize all are not created equal and for similar things, I think it would be interesting to start a list of the best websites / web applications built on specific languages/frameworks just to highlight the possibilities with each and give somebody like me motivation to say "How the heck was that done? Time to buy a book/take a class and learn." Tell me and I will forget, Show me and I will learn, Involve me and I will understand - Teton Lakota

  • Is there a unique computer identifier that can be used reliably even in a virtual machine?

    - by SaUce
    I'm writing a small client program to be run on a terminal server. I'm looking for a way to make sure that it will only run on this server and in case it is removed from the server it will not function. I understand that there is no perfect way of securing it to make it impossible to ran on other platforms, but I want to make it hard enough to prevent 95% of people to try anything. The other 5% who can hack it is not my concern. I was looking at different Unique Identifiers like Processor ID, Windows Product ID, Computer GUID and other UIs. Because the terminal server is a virtual machine, I cannot locate anything that is completely unique to this machine. Any ideas on what I should look into to make this 95% secure. I do not have time or the need to make it as secure as possible because it will defeat the purpose of the application itself. I do not want to user MAC address. Even though it is unique to each machine it can be easily spoofed. As far as Microsoft Product ID, because our system team clones VM servers and we use corporate volume key, I found already two servers that I have access to that have same Product ID Number. I have no Idea how many others out there that have same Product ID By 95% and 5% I just simply wanted to illustrate how far i want to go with securing this software. I do not have precise statistics on how many people can do what. I believe I might need to change my approach and instead of trying to identify the machine, I will be better off by identifying the user and create group based permission for access to this software.

  • Home and Small to Medium Enterprise network manufacturer choice, Netgear, Linksys or D-Link ?

    - by Kedare
    (Please don't close this post, it's a serious post so... Be cool, no trolls please, I need an answer ;p) Hello, I am looking for an alternative to Cisco (too expensive for me !) for semi-pro utilization (at home but with advanced feature (I'm studying in IT)) and in small/medium enterprises. I think I will choose between LinkSys (Including Cisco Small Business), Netgear and D-Link, but I've never really used these products, that what I need is a manufacturer that make "almost" all type of networking equipment (Like Cisco but cheaper..), here are my needs : I need almost all my products to be rackable I need a good warranty (Netgear lifetime waranty rulez!) I need an "unified" network environment I made a little comparison of the characteristics that interest me after hours of search on Internet (based on result found on many websites): (Prices are based on the ldlc-pro.com french website) Hotline/Support Quality: Netgear : Not so bad Linksys : Not so bad D-Link : Poor! Most common Warranty: Netgear : Unlimited Lifetime Warranty! Linksys : Limited 3 years warranty D-Link : Limited 5 years warranty (Unlimited in US but I'm on France :(...) VPN protocols compatibles with routers on endpoint mode: Netgear : Only IPSEC :( Linksys : IPSEC, PPTP, L2TP D-Link : IPSEC, PPTP, L2TP Cheaper 8 ports Gb switch : Netgear : 30€ Linksys : 47€ D-Link : 30€ Cheaper 48 ports + 1Gb uplink(s) administrable switch : Netgear : 263€ Linksys : 630€ D-Link : 600€ Cheaper VPN router : Netgear : 100€ Linksys : 80€ D-Link : 60€ Cheaper rackable switch : Netgear : 50€ Linksys : 87€ D-Link : 50€ Cheaper rackable and administrable switch : Netgear : 120€ Linksys : 370€ D-Link : 171€ Netgear and D-Link are in the same range of price, where Linksys is more expensives. I've searched for some other criteria ( the full comparison is here, in french with shop/source links: http://forums.jeuxonline.info/showthread.php?t=1072280 ) and made a final score for each manufacturer : SCORE including IP camera sub-score: Netgear : 6.2/10 Linksys : 7.3/10 D-Link : 7.0/10 SCORE excluding IP camera sub-score: Netgear : 6.9/10 Linksys : 7.0/10 D-Link : 6.7/10 On both case, Linksys wins. So here is my little comparison, but because I've never really used these stuffs, I need your help to make a decision on witch manufacturer choose for both my personnal and corporate use. So here are the questions : What manufacturer do you recommend me (Not cisco (except Small business)) ? Why ? Have you called the call center of the customer support of one of these manufacturer ? How it was ? Did you had problems or bad experiences with these equipments ? Any other advices ? ;) Thank you !

  • IIS6 Virtual Directory 500 Error on Remote Share

    - by David
    We have our servers at the server farm in a domain. Let's call it LIVE. Our developer computers live in a completely separate corporate domain, miles and miles away. Let's call it CORP. We have a large central storage unit (unix) that houses images and other media needed by many webservers in the server farm. The IIS application pools run as (let's say) LIVE\MediaUser and use those credentials to connect to a central storage share as a virtual directory, retrieve the images, and serve them as if they were local on each server. The problem is in development. On my development machine. I log in as CORP\MyName. My IIS 6 application pool runs as Network Service. I can't run it as a user from the LIVE domain because my machine isn't (and can not be) joined to that domain. I try to create a virtual directory, point it to the same network directory, click Connect As, uncheck the "Always use the authenticated user's credentials when validating access to the network directory" checkbox so that I can enter the login info, enter the credentails for LIVE\MediaUser, click OK, verify the password, etc. This doesn't work. I get "HTTP Error 500 - Internal server error" from IIS. The IIS log file reports sc-status = 500, sc-substatus = 16, and sc-win32-status = 1326. The documentation says this means "UNC authorization credentials are incorrect" and the Win32 status means "Logon failure: unknown user name or bad password." This would be all and good if it were anywhere close to accurate. I double- and trouble-checked it. Tried multiple known good logins. The IIS manager allows me to view the file tree in its window, it's only the browser that kicks me out. I even tried going to the virtual directory's Directory Security tab, and under Authentication and Access Control, I tried using the same LIVE domain username for the anonymous access credential. No luck. I'm not trying to run any ASP, ASP.NET, or other dynamic anything out of the virtual directory. I just want IIS to be able to load static images, css, and js files. If anyone has some bright ideas I would be most appreciative!

  • Windows 2008 R2 CA and auto-enrollment: how to get rid of >100,000 issued certificates?

    - by HopelessN00b
    The basic problem I'm having is that I have 100,000 useless machine certificates cluttering up my CA, and I'd like to delete them, without deleting all certs, or time jumping the server ahead, and invalidating some of the useful certs on there. This came about as a result of accepting a couple defaults with our Enterprise Root CA (2008 R2) and using a GPO to auto-enroll client machines for certificates to allow 802.1x authentication to our corporate wireless network. Turns out that the default Computer (Machine) Certificate Template will happily allow machines to re-enroll instead of directing them to use the certificate they already have. This is creating a number of problems for the guy (me) who was hoping to use the Certificate Authority as more than a log of every time a workstation's been rebooted. (The scroll bar on the side is lying, if you drag it to the bottom, the screen pauses and loads the next few dozen certs.) Does anyone know how to DELETE 100,000 or so time-valid, existing certificates from a Windows Server 2008R2 CA? When I go to delete a certificate now, now, I get an error that it cannot be delete because it's still valid. So, ideally, some way to temporarily bypass that error, as Mark Henderson's provided a way to delete the certificates with a script once that hurdle is cleared. (Revoking them is not an option, as that just moves them to Revoked Certificates, which we need to be able to view, and they can't be deleted from the revoked "folder" either.) Update: I tried the site @MarkHenderson linked, which is promising, and offers much better certificate manageability, buts still doesn't quite get there. The rub in my case seems to be that the certificates are still "time-valid," (not yet expired) so the CA doesn't want to let them be deleted from existence, and this applies to revoked certs as well, so revoking them all and then deleting them won't work either. I've also found this technet blog with my Google-Fu, but unfortunately, they seemed to only have to delete a very large number of certificate requests, not actual certificates. Finally, for now, time jumping the CA forward so the certificates I want to get rid of expire, and therefore can be deleted with the tools at the site Mark linked is not a great option, as would expire a number of valid certificates we use that have to be manually issued. So it's a better option than rebuilding the CA, but not a great one.

  • Is dual-booting an OS more or less secure than running a virtual machine?

    - by Mark
    I run two operating systems on two separate disk partitions on the same physical machine (a modern MacBook Pro). In order to isolate them from each other, I've taken the following steps: Configured /etc/fstab with ro,noauto (read-only, no auto-mount) Fully encrypted each partition with a separate encryption key (committed to memory) Let's assume that a virus infects my first partition unbeknownst to me. I log out of the first partition (which encrypts the volume), and then turn off the machine to clear the RAM. I then un-encrypt and boot into the second partition. Can I be reasonably confident that the virus has not / cannot infect both partitions, or am I playing with fire here? I realize that MBPs don't ship with a TPM, so a boot-loader infection going unnoticed is still a theoretical possibility. However, this risk seems about equal to the risk of the VMWare/VirtualBox Hypervisor being exploited when running a guest OS, especially since the MBP line uses UEFI instead of BIOS. This leads to my question: is the dual-partitioning approach outlined above more or less secure than using a Virtual Machine for isolation of services? Would that change if my computer had a TPM installed? Background: Note that I am of course taking all the usual additional precautions, such as checking for OS software updates daily, not logging in as an Admin user unless absolutely necessary, running real-time antivirus programs on both partitions, running a host-based firewall, monitoring outgoing network connections, etc. My question is really a public check to see if I'm overlooking anything here and try to figure out if my dual-boot scheme actually is more secure than the Virtual Machine route. Most importantly, I'm just looking to learn more about security issues. EDIT #1: As pointed out in the comments, the scenario is a bit on the paranoid side for my particular use-case. But think about people who may be in corporate or government settings and are considering using a Virtual Machine to run services or applications that are considered "high risk". Are they better off using a VM or a dual-boot scenario as I outlined? An answer that effectively weighs any pros/cons to that trade-off is what I'm really looking for in an answer to this post. EDIT #2: This question was partially fueled by debate about whether a Virtual Machine actually protects a host OS at all. Personally, I think it does, but consider this quote from Theo de Raadt on the OpenBSD mailing list: x86 virtualization is about basically placing another nearly full kernel, full of new bugs, on top of a nasty x86 architecture which barely has correct page protection. Then running your operating system on the other side of this brand new pile of shit. You are absolutely deluded, if not stupid, if you think that a worldwide collection of software engineers who can't write operating systems or applications without security holes, can then turn around and suddenly write virtualization layers without security holes. -http://kerneltrap.org/OpenBSD/Virtualization_Security By quoting Theo's argument, I'm not endorsing it. I'm simply pointing out that there are multiple perspectives here, so I'm trying to find out more about the issue.

  • How to have Windows Server DNS use hosts file to resolve specific host names

    - by user41079
    Hello, everyone, I'm facing a small problem with Windows Server 2003 DNS service. In my corporation, I'm running Microsoft DNS server(172.16.0.12) to do name resolution to my company intranet(domain name ends in dev.nls. resolving to IP 172.16..), and it is also configured as a DNS forwarder to forward other domain names(e.g. *.google.com , *.sf.net) to Internet real DNS servers. This internal DNS server never tends to serve users from outside world. And, we are running a mail server(serving incoming mail for a real Internet domain @nlscan.com) inside company firewall which can be accessed in either way: by connecting to 172.16.0.10 from within intranet. by connecting to mail.nlscan.com(resolved to 202.101.116.9) from Internet. Note that 172.16.0.10 and 202.101.116.9 is not the same physical machine. The 202 one is a firewall machine who do port forwarding of port 25 and 110 to intranet address 172.16.0.10 . Now my question: If users inside corporate LAN want to resolve mail.nlscan.com, it resolves to 202.101.116.9. That's correct and workable, BUT NOT GOOD, because the mail traffic goes to the firewall machine then bounces to 172.16.0.10 . I hope that our internal DNS server can intercept the name mail.nlscan.com and resolve it to 172.16.0.10 . So, I hope that I can write an entry in "hosts" file on 172.16.0.12 to do this. But, how can Microsoft DNS server recognize this "hosts" file? Maybe you suggest, why not have intranet user use 172.16.0.10 to access my mail server? I have to say it is inconvenient, suppose a user(employee) works on his laptop, daytime in office and nighttime at home. When he is at home, he cannot use 172.16.0.10 . Creating a zone for nlscan.com on our internal DNS server is not feasible, because the name server for nlscan.com domain is on our ISP, and it is responsible for resolving other host names and sub-domains under nlscan.com .

  • IE and Google Chrome timeout on an IIS6 hosted SSL page that Firefox handles well.

    - by Thomas
    Ok, here's the scenario: Up until a few weeks ago, none of us noticed anything wrong with the corporate website. People were using it without complaint. Then, a client complained that a specific page on the site was timing out for him, and only when he committed a POST action on a form filled with data. I checked it out, and it timed out for me, too. But, it only timed out in Google Chrome and IE, not in Firefox. Additionally, the same page, on the same server, but served from a different domain name (one not under the protection of SSL, either) does not time out under any browser. To clarify: https://www.mysite.com/changes.php times out on POST, but the same with http works fine. That distinction (SSL vs. Non-SSL) seems to be important, as nothing else has changed. Our certificate is valid, and Firefox detects no errors thrown by the page. I've looked at the Request and Response headers from the page, and they all follow the correct formats. Then, after wandering through the site, I noticed a few other things. Both IE and Chrome will frequently time out on any page that is PHP-based. They never time out on static images or html files. I've looked at the site from a variety of different servers, my home and work workstations, and my netbook. Because of that, I've discounted a viral infection, as I highly doubt a virus is going to hit every one of the machines to which I have access in exactly the same manner. My setup is: Server: Win2k3, II6, PHP 5.2.9-1. Clients: IE7, IE8, Chrome (regular and dev channel): Frequent timeouts on PHP pages. Firefox 2, Firefox 3: No timeouts. Firebug shows no errors or even lengthy periods serving the pages. I've spent 2 days searching for any tech knowledge that I can find, and my search parameters are all too general. Everyone has problems loading SSL pages in IE and Chrome for a wide variety of reasons. The infrequent nature of the timeouts and the fact that there are no errors being reported anywhere is starting to drive me insane. Does anyone have any insight on a problem like this?

  • IIS6 Virtual Directory 500 Error on Remote Share

    - by David Boike
    We have our servers at the server farm in a domain. Let's call it LIVE. Our developer computers live in a completely separate corporate domain, miles and miles away. Let's call it CORP. We have a large central storage unit (unix) that houses images and other media needed by many webservers in the server farm. The IIS application pools run as (let's say) LIVE\MediaUser and use those credentials to connect to a central storage share as a virtual directory, retrieve the images, and serve them as if they were local on each server. The problem is in development. On my development machine. I log in as CORP\MyName. My IIS 6 application pool runs as Network Service. I can't run it as a user from the LIVE domain because my machine isn't (and can not be) joined to that domain. I try to create a virtual directory, point it to the same network directory, click Connect As, uncheck the "Always use the authenticated user's credentials when validating access to the network directory" checkbox so that I can enter the login info, enter the credentails for LIVE\MediaUser, click OK, verify the password, etc. This doesn't work. I get "HTTP Error 500 - Internal server error" from IIS. The IIS log file reports sc-status = 500, sc-substatus = 16, and sc-win32-status = 1326. The documentation says this means "UNC authorization credentials are incorrect" and the Win32 status means "Logon failure: unknown user name or bad password." This would be all and good if it were anywhere close to accurate. I double- and trouble-checked it. Tried multiple known good logins. The IIS manager allows me to view the file tree in its window, it's only the browser that kicks me out. I even tried going to the virtual directory's Directory Security tab, and under Authentication and Access Control, I tried using the same LIVE domain username for the anonymous access credential. No luck. I'm not trying to run any ASP, ASP.NET, or other dynamic anything out of the virtual directory. I just want IIS to be able to load static images, css, and js files. If anyone has some bright ideas I would be most appreciative!

  • SSL support with Apache and Proxytunnel

    - by whuppy
    I'm inside a strict corporate environment. https traffic goes out via an internal proxy (for this example it's 10.10.04.33:8443) that's smart enough to block ssh'ing directly to ssh.glakspod.org:443. I can get out via proxytunnel. I set up an apache2 VirtualHost at ssh.glakspod.org:443 thus: ServerAdmin [email protected] ServerName ssh.glakspod.org <!-- Proxy Section --> <!-- Used in conjunction with ProxyTunnel --> <!-- proxytunnel -q -p 10.10.04.33:8443 -r ssh.glakspod.org:443 -d %host:%port --> ProxyRequests on ProxyVia on AllowCONNECT 22 <Proxy *> Order deny,allow Deny from all Allow from 74.101 </Proxy> So far so good: I hit the Apache proxy with a CONNECT and then PuTTY and my ssh server shake hands and I'm off to the races. There are, however, two problems with this setup: The internal proxy server can sniff my CONNECT request and also see that an SSH handshake is taking place. I want the entire connection between my desktop and ssh.glakspod.org:443 to look like HTTPS traffic no matter how closely the internal proxy inspects it. I can't get the VirtualHost to be a regular https site while proxying. I'd like the proxy to coexist with something like this: SSLEngine on SSLProxyEngine on SSLCertificateFile /path/to/ca/samapache.crt SSLCertificateKeyFile /path/to/ca/samapache.key SSLCACertificateFile /path/to/ca/ca.crt DocumentRoot /mnt/wallabee/www/html <Directory /mnt/wallabee/www/html/> Options Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory> <!-- Need a valid client cert to get into the sanctum --> <Directory /mnt/wallabee/www/html/sanctum> SSLVerifyClient require SSLOptions +FakeBasicAuth +ExportCertData SSLVerifyDepth 1 </Directory> So my question is: How to I enable SSL support on the ssh.glakspod.org:443 VirtualHost that will work with ProxyTunnel? I've tried various combinations of proxytunnel's -e, -E, and -X flags without any luck. The only lead I've found is Apache Bug No. 29744, but I haven't been able to find a patch that will install cleanly on Ubuntu Jaunty's Apache version 2.2.11-2ubuntu2.6. Thanks in advance.

  • I want to virtualize my workstation (Tier 1), Looking for Bare Metal Hypervisor for consumer grade components

    - by Chase Florell
    I find myself in this similar bind at least once a year. The bind whereby I'm either upgrading a motherboard, or an OS hard drive. It drives me crazy to have to reinstall Windows, Visual Studio, all my addins, reconfigure my settings etc... every single time. I have a layout and I like and I want to stick with it. My question is... Is there a Bare Metal Hypervisor on the market that will enable me to virtualize my consumer grade workstation? I really want to avoid Host/Client virtualization. Bare Metal is definitely a better way to go for my needs. Is this a good approach, or am I going to suffer some other undesirable side effects by doing this? Clarification My machine has very limited purposes. My primary use is Visual Studio 2010 Professional where I develop ASP.NET MVC Web Applications. The second piece of software that I use (that's system intensive) is Photoshop CS3. Beyond that, my applications are limited to Outlook, Internet Explorer, Firefox, Opera, Chrome, LinqPad, and various other (small) apps. Beyond this, I'm considering working on a node.js project and might run ubuntu on the same hypervisor if possible. System Specs: Gigabyte Motherboard Intel i7 920 12 GB Ram basic 500GB 7200RPM HDD for OS 4 VelociRaptors in Raid 1/0 for build disk Dual GTS250 (512MB) Graphics cards (non SLI) for quad monitors On a side note I also wouldn't be opposed to an alternative suggestion if the limitations are too great. I could install the ESXi (or Zen Server) on my box, and build a separate "thin client" to RDP into the virtual machine. It appears as though RDP supports dual monitors. Edit (Dec 9, 2011) It's been nearly a year since I first asked this question. Since then, there have been a lot of great strides in Hypervisor technology... AND MokaFive is now released for corporate use. I'd love to dig into this question a little more and find out if there is a solid BareMetal Hypervisor for workstations running consumer grade components (IE: not Dell, HP, Lenovo, Etc).

  • How can I create an appointment on a shared Outlook calendar

    - by roryhewitt
    This isn't as basic a question as it may seem. Hence all the descriptive text... I and my team use Outlook 2007. I have my own personal calendar and also I share a calendar with others in my team (which is mainly used to notify everyone of vacations etc.). The others in my team are NOT technical people. I would like to create a shortcut or template that any of us can use to create an appointment in the shared calendar. My initial though was to create a new appointment, but rather than actually put it in the calendar, I would save it as an Outlook Template (.oft) file. Once created, I would send this to my team and tell them to put it in their Templates file and put a shortcut on their desktop. Then, if they want to put a vacation in the shared calendar, they just double-click on the shortcut, change the dates etc. and then save & close it. However, when I do that, it doesn't save the fact that it's an appointment on the shared calendar - it just adds the appointment to the team member's personal calendar. There doesn't seem to be a way to specify a calendar in the template. I've also tried this by saving the template as a .ics or .vcs file, with no better luck. Additionally, if a team member adds an appointment to the shared calendar, other 'sharees' aren't notified, unless the appointment is actually created as a meeting and the other sharees are explicitly invited. I found this online (http://office.microsoft.com/en-us/outlook-help/keep-everyone-informed-about-time-away-from-the-office-HA010209819.aspx) which APPEARS to say that what I want to do isn't built in functionality (since it shows a bunch of steps to go through. I'd PREFER not to have to add this stuff to everyone else's personal calendar directly. So... Is this possible to do, natively (i.e. directly in Outlook)? Would a Sharepoint calendar make more sense and allow this functionality? Is there a way to do what I want which will allow the other team members to be notified? Like I said, I'm looking for as simple an interface as possible - these people aren't going to want to do much more than open something and change dates. Additionally, they're probably not going to have any fancy software on their PC's, although they will be up to date with Java and (maybe) .NET frameworks. Also, before anyone gets funny, yes, this has to work with Outlook 2007, as it's a corporate standard - we're not able to change that, even though e.g. Google Calendar would do this wonderfully. Obviously if this functionality is available in Outlook 2010, then fantastic - we might be able to upgrade. Thanks!

  • Network switching issues with MacOS 10.7?

    - by Denis
    I'm having a wired problem and hope somebody can tip me, what way should I dig to. I'm using MacBookPro with Lion 10.7.3 both at my working place & at home. At working place, we have a domain-based network with 802.1x authorization (more than 400 computers) and to connect it I'm using Ethernet cable. IP range is 10.10.2.*. All network settings are setup automatically by DHCP. Also, in settings, I have Network Account Server setup in the User&Groups Settings for my work Domain server - and it is available only from corporate network. At home, I have an ADSL router, that shares Internet connection by WiFi in NAT mode. I'm using WiFi to connect it. Router gives out addresses from 192.168.1.* range and all settings are also set up by router's DHCP. So, my problem is the following. When I come back home from the office, I open my MacBook and AirPort automatically connects my WiFi network. After this, for about 1 minute I'm able to browse sites & ping hosts successfully. But after this minute, network connection is broken down. All pings return time-out. trace route to google.com stops on 192.168.1.1 (which is my router). This lasts for 3-4 minutes. After that network connection is automatically repaired and all pings go smoothly again. At the same time, when my MacBook return timeouts, I can successfully ping any host from my wife's MacBook - so this doesn't look like router issue. When I come to the office, I don't have any issues and Internet connection is available & stable moments after ethernet cable plugged in. Do anybody has any clues about this? What should I monitor & what settings look for resolving this issue? Please, ask, what additional information should I provide. Hoping for good advice & thanks in advance!
