• MOSSLover Lives On&hellip;

  - by MOSSLover

  A while back, maybe 6 months, I got some bad news about 2010.  Microsoft was removing Office from the MOSS equivalent of 2010, so basically my alias would be obsolete the second 2010 caught on in the community.  I thought about it for some time.  I had some discussions with friends in the community.  I even noticed that the MOSSMan changed his twitter id.  I started my blog around a WSS 3.0 project when I worked for LRS in there St. Louis Office in February/March 2007.  So I think it’s fitting to keep the name, because my community involvement centers around 2007.  My first ever speaking ordeal was at the Kansas City Office Geeks meeting in November of 2007 on Disaster Recovery where about three people attended.  The first user group meeting I ever attended was around the month of June 2007 at the KC .Net User Group about two weeks after my braces were installed.  It’s definitely fitting to say that 2007 paved the way for everything that happened in the past 2/2 1/2 years.  If anyone asks what MOSSLover means I added a description on twitter and I also added my name.  I added my name for other reasons, because I’m sick of people thinking I am the guy in the photo.  Also, I’d like people to recognize me for who I am.  Everyone should expect less of the hat in the upcoming year and more of my hair.  I’ve taken a vow to wear the hat less and less this year.  I am sick of buying hats, plus I want to move forward to gain more self confidence.  The hat does not really help.  I will still wear a t-shirt and jeans in most of my presentations.  That is who I am and it will not change any time soon.  If you expect to see me in a skirt good luck with that as it won’t be happening unless I am forced at gun point.  I hope you guys have a good weekend.  Later all… Technorati Tags: MOSSLover,Cardinal's Hat,Becky Isserman

• How can I be prepared to join a company?

  - by Aerovistae

  There's more to it than that, but this title was the best way I could think of to sum it up. I'm a senior in a good computer science program, and I'm graduating early. About to start interviews and all whatnot. I'm not a super-experienced programmer, not one of those people who started in middle school. I'm decent at this, but I'm not among the best, not nearly. I have to do an awful lot of googling. So today I'm meeting some fellow for lunch at a campus cafe to discuss some front-end details when this tall, good-looking guy begs pardon, says he's new to campus, says he's wondering if we know where he can go to sign up for recruiting developers. Quickly evolves into long conversation: he's the CEO of a seems-to-be-doing-well start-up. Hiring passionate interns and full-times. Sounds great! I take one look at his site on my own computer later, immediately spot a major bug. No idea how to fix it, but I see it. I go over to the page code, and good god. It's the standard amount of code you would expect from a full-scale web application, a couple dozen pages of HTML and scripts. I don't even know where to start reading it. I've built sites from scratch, but obviously never on that scale, nor have I ever worked on one of that scale. I have no idea which bit might generate the bug. But that sets me thinking: How could someone like me possibly settle into an environment like that? A start-up is a very high-pressure working environment. I don't know if I can work at that pace under those constraints-- I would hate to let people down. And with only 10 employees, it's not like anyone has much time to help you get your bearings. Somewhere in there is a question. Can you see it? I'm asking for general advice here. Maybe even anecdotal advice. Is joining a start-up right out of college a scary process? Am I overestimating what it would take to figure out the mass of code behind this site? What's the likelihood a decent but only moderately-experienced coder could earn his pay at such a place? For instance, I know nothing of server-side/back-end programming. Never touched it. That scares me.

• HTML5 game programming style

  - by fnx

  I am currently trying learn javascript in form of HTML5 games. Stuff that I've done so far isn't too fancy since I'm still a beginner. My biggest concern so far has been that I don't really know what is the best way to code since I don't know the pros and cons of different methods, nor I've found any good explanations about them. So far I've been using the worst (and propably easiest) method of all (I think) since I'm just starting out, for example like this: var canvas = document.getElementById("canvas"); var ctx = canvas.getContext("2d"); var width = 640; var height = 480; var player = new Player("pic.png", 100, 100, ...); also some other global vars... function Player(imgSrc, x, y, ...) { this.sprite = new Image(); this.sprite.src = imgSrc; this.x = x; this.y = y; ... } Player.prototype.update = function() { // blah blah... } Player.prototype.draw = function() { // yada yada... } function GameLoop() { player.update(); player.draw(); setTimeout(GameLoop, 1000/60); } However, I've seen a few examples on the internet that look interesting, but I don't know how to properly code in these styles, nor do I know if there are names for them. These might not be the best examples but hopefully you'll get the point: 1: Game = { variables: { width: 640, height: 480, stuff: value }, init: function(args) { // some stuff here }, update: function(args) { // some stuff here }, draw: function(args) { // some stuff here }, }; // from http://codeincomplete.com/posts/2011/5/14/javascript_pong/ 2: function Game() { this.Initialize = function () { } this.LoadContent = function () { this.GameLoop = setInterval(this.RunGameLoop, this.DrawInterval); } this.RunGameLoop = function (game) { this.Update(); this.Draw(); } this.Update = function () { // update } this.Draw = function () { // draw game frame } } // from http://www.felinesoft.com/blog/index.php/2010/09/accelerated-game-programming-with-html5-and-canvas/ 3: var engine = {}; engine.canvas = document.getElementById('canvas'); engine.ctx = engine.canvas.getContext('2d'); engine.map = {}; engine.map.draw = function() { // draw map } engine.player = {}; engine.player.draw = function() { // draw player } // from http://that-guy.net/articles/ So I guess my questions are: Which is most CPU efficient, is there any difference between these styles at runtime? Which one allows for easy expandability? Which one is the most safe, or at least harder to hack? Are there any good websites where stuff like this is explained? or... Does it all come to just personal preferance? :)

• Access Control Service v2: Registering Web Identities in your Applications [code]

  - by Your DisplayName here!

  You can download the full solution here. The relevant parts in the sample are: Configuration I use the standard WIF configuration with passive redirect. This kicks automatically in, whenever authorization fails in the application (e.g. when the user tries to get to an area the requires authentication or needs registration). Checking and transforming incoming claims In the claims authentication manager we have to deal with two situations. Users that are authenticated but not registered, and registered (and authenticated) users. Registered users will have claims that come from the application domain, the claims of unregistered users come directly from ACS and get passed through. In both case a claim for the unique user identifier will be generated. The high level logic is as follows: public override IClaimsPrincipal Authenticate( string resourceName, IClaimsPrincipal incomingPrincipal) {     // do nothing if anonymous request     if (!incomingPrincipal.Identity.IsAuthenticated)     {         return base.Authenticate(resourceName, incomingPrincipal);     } string uniqueId = GetUniqueId(incomingPrincipal);     // check if user is registered     RegisterModel data;     if (Repository.TryGetRegisteredUser(uniqueId, out data))     {         return CreateRegisteredUserPrincipal(uniqueId, data);     }     // authenticated by ACS, but not registered     // create unique id claim     incomingPrincipal.Identities[0].Claims.Add( new Claim(Constants.ClaimTypes.Id, uniqueId));     return incomingPrincipal; } User Registration The registration page is handled by a controller with the [Authorize] attribute. That means you need to authenticate before you can register (crazy eh? ;). The controller then fetches some claims from the identity provider (if available) to pre-fill form fields. After successful registration, the user is stored in the local data store and a new session token gets issued. This effectively replaces the ACS claims with application defined claims without requiring the user to re-signin. Authorization All pages that should be only reachable by registered users check for a special application defined claim that only registered users have. You can nicely wrap that in a custom attribute in MVC: [RegisteredUsersOnly] public ActionResult Registered() {     return View(); } HTH

• TechEd 2010 Day Three: The Database Designer (Isn't)

  - by BuckWoody

  Yesterday at TechEd 2010 here in New Orleans I worked the front-booth, answering general SQL Server questions for the masses. I was actually a little surprised to find most of the questions I got were from folks that wanted to know more about Stream Insight and Master Data Services. In past conferences I've been asked a lot of "free consulting" questions, about problems folks have had from older products. I don't mind that a bit - in fact, I'm always happy to help in any way I can. But this time people are really interested in the new features in the product, and I like that they are thinking ahead, not just having to solve problems in production. My presentation was on "Database Design in an Hour". We had the usual fun, and SideShow Bob made an appearance - I kid you not. The guy in the back of the room looked just like Sideshow Bob, so I quickly held a "bes thair" contest, and he won. Duing the presentation, I explain the tools you can use to design databases. I also explain that the "Database Designer" tool in SQL Server Management Studio (SSMS) isn't truly a desinger - it uses non-standard notation, doesn't have a meta-data dictionary, and worst of all, it works at the physical level. In other words, whatever you do in SSMS will automatically change the field/table/relationship structures in the database. We fixed this in SSMS 2008 and higher by adding an option to block that, but the tool is not a good design function nonetheless. To be fair, no one I know of at Microsoft recommends that it is - but I was shocked to hear so many developers in the room defending it as a good tool. I think the main issue for someone who doesn't have to work with Relational Systems a great deal is that it can be difficult to figure out Foreign Keys. The syntax makes them look "backwards", so it's just easier to grab a field and place it on the table you want to point to. There are options. You can download a couple of free tools (CA has a community edition of ER-WIN, Quest has one, and Embarcadero also has one) and if you design more than one or two databases a year, it may be worth buying a true design tool. For years I used Visio, but we changed it so that it doesn't forward-engineer (create the DDL) any more, so it isn't a true design tool either. So investigate those free and not-so-free tools. You'll find they help you in your job - but stay away from the Database Designer in SSMS. Or I'll send Sideshow Bob over there to straighten you out.

• How quickly to leave contract-to-hire gig where you don't want to be hired? [closed]

  - by nono

  So you move to a big new city with tons of software development opportunity, having taken a six month contract-to-hire job. The company treats you really well and has a good team and work environment. However, the recruiter assured you when offering the gig that it would be a good position in which you can advance your learning from more senior developers (a primary concern of yours) but you're starting to realize that a job recruiter isn't going to understand that the team in question isn't very up on modern software practices (you start to sympathize with this guy and read his post over and over again: http://stackoverflow.com/questions/1586166/career-killer-nhibernate-oop-design-patterns-domain-driven-design-test-driv) and that much of the company's software is very old and very very poorly architected, and the company (like so many others) seems to be only concerned with continually extending the software without investing in any structural improvements. You're absolutely dismayed at how long it takes your team (including) to fulfill simple feature requests (maybe 500-1000% longer than with better designed software that you've worked on in the past), but no one else there seems to think anything of it. You find that the work and the company's business are intensely uninteresting to you, but due to the convoluted design of their various software systems, fulfilling the work will require as much mental engagement as any other development position. You feel a bit naive about not having asked the right questions during your interview process, and for not having anticipated that your team at your former podunk company might possibly be light-years ahead of any team in Big Shiny City, but you know you don't want to stay at this place, and (were it not for your personal, after-hours studying and personal programming efforts) fear that you might actually give a worse interview after completing your 6 months than you did when you started at the place. You read about how hard of a time local companies are having filling their positions with qualified software development candidates. You read all sorts of fabulous sounding job postings online and feel like you're really missing out. In spite of the comfortable environment you feel like you would willingly accept a somewhat more demanding or aggressive lifestyle to feel like you are learning and progressing and producing something meaningful. My questions are: how quickly do you leave and how do you go about giving a polite reason for departing? The contract is written to allow them to "can" you and to allow you to leave with 2 weeks notice. Do you ethically owe the 6 months? Upon taking the position, the company told you they were not interested in candidates who were intending to only stay for 6 months and then leave (you were not intending to bail after 6 months, at that time), so perhaps they might be fine if you split now, knowing that you don't want to stick around for the full time hire?

• Boot error aftter clean Ubuntu 13.04 install: [Reboot and select proper boot device]

  - by IcarusNM

  I am having the same problem as this guy where a fresh Ubuntu install completes beautifully but will not boot. I get the ASUS (?) "Reboot and select proper boot device" error, first with Xubuntu 13.10 and after finally giving up there, and Xubuntu 13.4, I am back to regular Ubuntu 13.4. ASUS motherboard Z77, Intel chipset. Standard internal SATA 500GB HD. 64-bit. All-new hardware less than 3 months old. It was running Ubuntu 12.04LTC great until I tried this upgrade. I have re-installed from scratch every which way: with LVM, without LVM; with the default partitions, with my own partitions. With ext3 or ext4. Alongside; replace; upgrade. No difference. On the last two tries, I have booted afterward from the same USB stick, downloaded and run boot-repair, and now I guess I am off to the boot-repair support email with my URLs from that. It did all kinds of cool stuff but ultimately made no difference. I never got anything like this with Ubuntu 12.04. I've now probably re-installed Ubuntu 13.04 ten times slightly different ways. I finally found how to skip the language packs, so at least that sped things up! :) This starts from the ubuntu-13.04-desktop-amd64.iso and UNetbootin as suggested on the official instructions for USB thumb drive creation from OSX. That part all works fine (booting the USB on the PC and trying Ubuntu and/or installing from there on the PC HD.) I have no CD drive on this PC, but I suppose I could get one. I would rather find some Linux install that works from USB like I've always done. After running boot-repair twice, in the ASUS BIOS I now see three different UEFI boot options in the priority list, and they are all labeled exactly the same: ubuntu (P6: WDC WD5000AAKX-00U6AA0) Then there's a non-UEFI option: P6: WDC WD5000AAKX-00U6AA0 (476940MB) And a fifth option appeared after the first boot-repair: Windows Boot Manager (P6: WDC WD5000AAKX-00U6AA0) I have tried all 5 of these, and I get exactly the same error. I have never had Windows installed on this HD. ASUS is calling it Windows Boot Manaer but I presume that's a mistaken label for whatever boot-repair did. I can boot on USB and run GParted and it looks great. The partitions all look normal. I found another case of this online with no solution posted. I can't find much about it online. Needs a Master Boot Record wipe/redo?? I'm not sure how.

• Insanity&ndash;Day 1

  - by D'Arcy Lussier

  Some people do those posts about “Here’s what I’m going to do to change my life”. I don’t really like those. I’m a “don’t tell me what you’re going to do, tell me what you’re doing/have done” type of guy. So while I could say how I’m going to change my life and be healthier and happier and thinner in 60 days, I’m just going to tell you how I’m progressing through the Insanity workout. Insanity is a workout-in-a-box. It’s a collection of DVDs that you work out to. Nothing new here, except that the program is intense. It’s core tenet of the program is intensity – you workout at an elevated heart rate for 3 minutes with a short break in between, as opposed to traditional interval training where you go hard for a short time and recover for a few minutes. The other aspect of it is commitment. There is a timetable to follow – you workout 6 days a week with one rest day. This isn’t meant to be a “pick it up whenever you feel like it” type of program. The videos themselves are kind of…I don’t want to say low quality, but not as polished as I expected. Maybe that’s what they were going for. By that I mean they show shots of cameramen and the production equipment during the workout. Otherwise, it’s the Insanity leader Shawn T. leading a group of pretty fit folks through this gruelling workout. And ultimately, those little production nit-picks are irrelevant compared to the actual workout. Holy crap. I haven’t done an aerobics class in like…ever. And watching the video before my actual workout, I thought “That doesn’t look too hard”. Believe me, it is. No weights, no machines, just various exercises done in circuits and with increasing speed. By the end of the workout, I was drenched. So that was day one. Some stats just so I can track it: I’m 286 lbs at my last weigh-in a week ago or so. Should be interesting to see what 60 days of this does! D

• Usage of Pirated software at a company

  - by hakesh

  Hi, I am redirected from stack over flow since the topic is ethics rather than about programming. Thank you for letting me know that. and please give me advices. So, I started to work at a company as an engineer a couple of months ago. It's a small company and what they basically do is answering service on phones. Now they are switching from normal phones to IP phones so that computers take more important place in the work. However, all the computers used by workers are equipped with pirated software ,even their operating systems are. Moreover, they don't even buy one license to make copies for other computers. In other words, they do not spend any money for the software in office. I am not saying copying a licensed one is legit, but the situation is too much. There is one guy who did installing those pirated soft. He does not feel any sense of guilt and even justified when I asked about it. and he is not even a specialist. He just searched on the internet to install pirated software. Our boss does not have any knowledge of computers, so he took cheaper way. How do you guys think about this? Since I am still new to the company, I am not doing maintenance or managing on those cracked computers. But I have to use those software daily. And later on I will be doing support, help desk kind of staff. I really don't want to take responsibility for operating pirated software. and from an aspect of developer and engineer, pirated software are not able to get legal support and it may work unexpectedly. So, I am thinking about changing job. Am I thinking too much? should I wait until I have more credit from the boss and try to change his policy? So far, the boss does not take any words from me. Any opinions are welcome. Thank you

• Did I choose proper career path? [closed]

  - by Liston Catch

  I am a C# Junior. My company has it's own enterprise documents-flow system written, my job along with 10 other programmers is to write modules/add-ons for it. I am totally bored of this job, I dont like Microsoft's technologies stack (dont hate me here, just subjective), but it's plain boring, enterprise is boring (subjective again, everyone's tastes differ), days on this work last long and I am tired of it. In short - I dont like my job. In my spare time I am doing PHP-development and I totally like it. I am also doing web-design, so I am LAMP-kind of guy who loves his Ubuntu and does design aswell. I know that most programmers don't do design themselves, so some person is either all about design or all about coding, but I enjoy both and do both. I often get interesting sites orders, I love to make whole websites with all the design, I love the feeling of site completeness, I enjoy talking with customers. I like that PHP is simple and skill cap is lower than one of java, meaning I can become expert in it after some years. But C# (and J2EE also) pay more, and I am doing really good in C#. But I dont like it. I can go for J2EE, platform itself seems more fun to me rather than .NET, but EE development is still boring to me. But it seems higher payed, easier to find job (since PHP is too common for its easiness. But if you are expert in something it doesnt matter, right? Just a higher skillcap.) Question: I want to go on with freelance. I want to have an opportunity to start my own startup in web. Actually I have a browser-game already written by myself, it earns me around 500$ per month which I am really proud of since I am 21 only and still noob in coding. I want to find part-time PHP job. 3 days per week so I can get some stable income, I can work in team and learn from them, social factor matters aswell as ensurance and diversity. I also want my total income (freelance + part-time job + own startup maybe)to be not too much less than one I have working in EE development sector. Maximum of 25% lower, but not more. Is it all possible if I stick with web-development (LAMP + HTML/CSS/JS/Jquery/AJAX)? Or is it easier to reach my goals with EE development?

• Is it unusual for a small company (15 developers) not to use managed source/version control?

  - by LordScree

  It's not really a technical question, but there are several other questions here about source control and best practice. The company I work for (which will remain anonymous) uses a network share to host its source code and released code. It's the responsibility of the developer or manager to manually move source code to the correct folder depending on whether it's been released and what version it is and stuff. We have various spreadsheets dotted around where we record file names and versions and what's changed, and some teams also put details of different versions at the top of each file. Each team (2-3 teams) seems to do this differently within the company. As you can imagine, it's an organised mess - organised, because the "right people" know where their stuff is, but a mess because it's all different and it relies on people remembering what to do at any one time. One good thing is that everything is backed up on a nightly basis and kept indefinitely, so if mistakes are made, snapshots can be recovered. I've been trying to push for some kind of managed source control for a while, but I can't seem to get enough support for it within the company. My main arguments are: We're currently vulnerable; at any point someone could forget to do one of the many release actions we have to do, which could mean whole versions are not stored correctly. It could take hours or even days to piece a version back together if necessary We're developing new features along with bug fixes, and often have to delay the release of one or the other because some work has not been completed yet. We also have to force customers to take versions that include new features even if they just want a bug fix, because there's only really one version we're all working on We're experiencing problems with Visual Studio because multiple developers are using the same projects at the same time (not the same files, but it's still causing problems) There are only 15 developers, but we all do stuff differently; wouldn't it be better to have a standard company-wide approach we all have to follow? My questions are: Is it normal for a group of this size not to have source control? I have so far been given only vague reasons for not having source control - what reasons would you suggest could be valid for not implementing source control, given the information above? Are there any more reasons for source control that I could add to my arsenal? I'm asking mainly to get a feel for why I have had so much resistance, so please answer honestly. I'll give the answer to the person I believe has taken the most balanced approach and has answered all three questions. Thanks in advance

• Should we persist with an employee still writing bad code after many years?

  - by user94986

  I've been assigned the task of managing developers for a well-established company. They have a single developer who specialises in all their C++ coding (since forever), but the quality of the work is abysmal. Code reviews and testing have revealed many problems, one of the worst being memory leaks. The developer has never tested his code for leaks, and I discovered that the applications could leak many MBs with only a minute of use. User's were reporting huge slowdowns, and his take was, "it's nothing to do with me - if they quit and restart, it's all good again." I've given him tools to detect and trace the leaks, and sat down with him for many hours to demonstrate how the tools are used, where the problems occur, and what to do to fix them. We're 6 months down the track, and I assigned him to write a new module. I reviewed it before it was integrated into our larger code base, and was dismayed to discover the same bad coding as before. The part that I find incomprehensible is that some of the coding is worse than amateurish. For example, he wanted a class (Foo) that could populate an object of another class (Bar). He decided that Foo would hold a reference to Bar, e.g.: class Foo { public: Foo(Bar& bar) : m_bar(bar) {} private: Bar& m_bar; }; But (for other reasons) he also needed a default constructor for Foo and, rather than question his initial design, he wrote this gem: Foo::Foo() : m_bar(*(new Bar)) {} So every time the default constructor is called, a Bar is leaked. To make matters worse, Foo allocates memory from the heap for 2 other objects, but he didn't write a destructor or copy constructor. So every allocation of Foo actually leaks 3 different objects, and you can imagine what happened when a Foo was copied. And - it only gets better - he repeated the same pattern on three other classes, so it isn't a one-off slip. The whole concept is wrong on so many levels. I would feel more understanding if this came from a total novice. But this guy has been doing this for many years and has had very focussed training and advice over the past few months. I realise he has been working without mentoring or peer reviews most of that time, but I'm beginning to feel he can't change. So my question is, would you persist with someone who is writing such obviously bad code?

• Access to message queuing system is denied MSMQ?

  - by user1401694

  My problem is a little confusing. I have 2 servers (Windows Server 2008 R2) with MSMQ installed and I want to use Server B to consume a MessageQueue on Server A. When I try to Receive it always throws a message error: "Access to message queuing system is denied.". IP between them. Server A: 172.31.23.130 Server B: 172.31.23.195 FormatName:Direct=TCP:172.31.23.195\private$\queuesource (It's working for Sends) I can ping each server from the other; The firewall is disabled; The "queuesource" has Full Control to "Everyone", "Anonymous Logon", "Network", "Network Services"; Journal is disabled; Authentication is ok; The queue is Transactional. My code in .Net C# is basically like this: MessageQueue _sourceQueue = new MessageQueue(); _sourceQueue.Path = "FormatName:Direct=TCP:172.31.23.195\private$\queuesource"; _sourceQueue.Receive(); // << here throw an exception. Actually I'm using the Private Queue only to avoid Active Directory's problems. For example, if the server DNS fail all network fail. I don't know what do anymore.

• Diagnosing permission problems with Cobian Backup to network share

  - by DaveBurns

  I'm running the latest Cobian 11. I have a Synology DS412 NAS. All of my machines (Mac and Windows) access this just fine when I'm logged in and I browse to it manually. I have Cobian installed as a service on two Windows machines: WinXP SP3 and Win7 x64. On both machines, the service is set to log on with my user account which is in the Windows administrator group. Backups on both machines fail with the message "Couldn't create the destination directory "\nas1\backups\foo\bar\": The filename, directory name, or volume label syntax is incorrect". I have tried setting the NAS's share to allow anonymous read/write access but it made no difference. Although I want the backups to run unattended in the middle of the night, I have tested them by running them manually while I'm logged in but no luck. Before starting that, I make sure that I can browse to the NAS with Explorer to ensure that any authentication session with Windows and the NAS has not expired. Still no luck. I have tried creating that destination directory both on the NAS before the backup and deleting it so the backup job could create it with the client's credentials but no luck. The usual answer in the Cobian support forums is that there is a permission problem. I agree. But at this point, what can I do to diagnose this further?

• SQL Server 2008 Cluster Installation - First network name always fails

  - by boflynn

  I'm testing failover clustering in Windows Server 2008 to host a SQL Server 2008 installation using this installation guide. My base cluster is installed and working properly, as well as clustering the DTC service. However, when it comes time to install SQL Server, my first attempt at installation always fails with the same message and seems to "taint" the network name. For example, with my previous cluster attempt, I was installing SQL Server as VSQL. After approximately 15 attempts of installation and trying to resolve the errors, e.g. changing domain accounts for SQL, setting SPNs, etc., I typoed the network name as VQSL and the installation worked. Similarly on my current cluster, I tried installing with the SQL service named PROD-C1-DB and got the same errors as last time until I tried changing the name to anything else, e.g. PROD-C1-DB1, SQL, TEST, etc., at which point the install works. It will even install to VSQL now. While testing, my install routine was: Run setup.exe from patched media, selecting appropriate options After the install fails, I'd chose "Remove node from a SQL Server failover cluster" and remove the single, failed, node Attempt to diagnose problem, inspect event logs, etc. Delete the computer account that was created for the SQL Service from Active Directory Delete the MSSQL10.MSSQLSERVER folder from the shared data drive The error message I receive from the SQL Server installer is: The following error has occurred: The cluster resource 'SQL Server' could not be brought online. Error: The group or resource is not in the correct state to perform the requested operation. (Exception from HRESULT: 0x8007139F) Along with hundreds of the following errors in the Application event log: [sqsrvres] checkODBCConnectError: sqlstate = 28000; native error = 4818; message = [Microsoft][SQL Server Native Client 10.0][SQL Server]Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'.

• Configuring external SMTP server on Azure VM - messages staying in queue

  - by Steph Locke

  I have an external SMTP provider: auth.smtp.1and1.co.uk I am trying to send SQL Server Reporting Services emails via this on an Windows 2012 Azure VM. It is configured sufficiently correctly for emails to be generated, but I've not configured something or mis-configured something as the emails then stay in the queue. Setup details Configured SMTP Virtual Server General: IP Address: Fixed value Access: Access Control: Authentication: ticked Anonymous access Access: Connection Control: All except the list below (which is empty) Access: relay restrictions: Only the list below (which contains 127.0.0.1), ticked 'allow all..' option Delivery: Outbound Security...:Basic Authentication with username and password completed, ticked TLS encryption Delivery: Outbound connections...:TCP port=587 Delivery: Advanced: FQDN=ServerName, smarthost=auth.smtp.1and1.co.uk I then set the following SSRS rsreportserver.config values: <SMTPServer>100.92.192.3</SMTPServer> <SendUsing>2</SendUsing> <SMTPServerPickupDirectory> c:\inetpub\mailroot\pickup </SMTPServerPickupDirectory> <From>[email protected]</From> Tried so far 1) turning the smtp service off and on again (just in case) 2) run SMTPDiag with no errors (also no emails) 3) tried turning off the firewall for the ports (and more generally to see if it made a difference) 4) tried generation from powershell which resulted with message in queue 5) added 25 and 857 as endpoint 6) perused the event log and found some warnings that appear to be about the recipient Message delivery to the remote domain 'gmail.com' failed for the following reason: Unable to bind to the destination server in DNS. Message delivery to the host '212.227.15.179' failed while delivering to the remote domain 'gmail.com' for the following reason: The remote server did not respond to a connection attempt. 7) tried pinging but this appears to be blocked on azure 8) tried more powershell sending on different domains variants (localhost, boxname, internal ip used in smtp properties, 127.0.0.1) - none resulting in success 9) tried adding a remote domain - no change Could anyone recommend what step 10 should be in fixing this issue please?

• How-To Configure Weblogic, Agile PLM and an F5 LTM

  - by Brian Dunbar

  Agile, Weblogic, and an F5 walk into a bar ... I've got this Agile PLM v 9.3 Running on WebLogic, two managed servers. An F5 BigIP LTM. We're upgrading from Agile v 9.2.1.4 running on OAS. The problem is that while the Windows client works fine the Java client does not. My setup is identical to one outlined in F5's doc: http://www.f5.com/pdf/deployment-guides/bea-bigip45-dg.pdf When I launch the java client it returns this error "Server is not valid or is unavailable." Oracle claims Agile PLM is setup correctly, but won't comment on the specifics of the load balancer. F5 reports the configuration is correct but can't comment on the specifics of the application. I am merely the guy in a vortex of finger-pointing who wants my application to work. It's that or give up on WLS and move back to OAS. Which has it's own problems but at least we know how it works. Any ideas?

• Windows 2003 Domain Controller Very Upset about NIC Teaming

  - by Kyle Brandt

  I set up BACS (Broadcom Teaming) to team two NIC on a Windows 2003 Active Directory Domain Controller. Networking still works okay, I can ping the gateway etc, but both DNS and Active Directory fail to start with various 40xx errors. The team that I created is Smart load Balancing with Failover, with one backup and only one in smart load balancing (So really it is just failover). I have the team the same IP address that the single active NIC had before. Anyone seen this before, or have any ideas what the problem might be? Event Type: Error Event Source: DNS Event Category: None Event ID: 4015 Date: 3/7/2010 Time: 10:33:03 AM User: N/A Computer: ADC Description: The DNS server has encountered a critical error from the Active Directory.

• Windows Server 2008 / SQL 2008 Licensing for Authenticated Web Application

  - by MikeM

  Hello, I'm trying to crunch some numbers to see what the software costs involved are for hosting an application we are developing. Users will not be anonymous - they will need to log in. SQL Server 2008: SQL Server licensing is easy - it will be licensed per-processor. No real fuss there. The cost of CALs would be much higher for the number of users as compared to the processor licenses. Windows Server 2008: This is where it gets trickier. We need to license the OS for both the web servers (there will be a couple) plus the database servers (also a couple). The Web Servers could run on the Web Edition without a need for CALs, but if you continue reading, you will see that may not matter much because I will likely have user CALs for each user anyway. We can't use the "External Connector" for any of the Windows licenses, because that doesn't cover customers who are paying to access a hosted application. We can't use the Web Edition for the SQL Servers because that license only allows database running on Web Edition to host data for the local web application (i.e. other web servers can't connect to it). So that leaves us with the "full" editions of Windows Server for the database server OS. I find this a little rediculous, and I feel as though I must be missing something, but it looks to me like I will actually need to buy a CAL for every user who signs up to use our service. I feel like I'm missing something because that means that for every user, I have to shell out $40 for a CAL. That could be one or two years' worth of revenue from each user for an inexpensive service! Is there any way to serve a web application to authenticated users without paying for individual Windows Server CALs, if the web servers and SQL servers are seperate boxes?

• Postfix: LDAP not working (warning: dict_ldap_lookup: Search base not found: 32: No such object)

  - by Heinzi

  I set up LDAP access with postfix. ldapsearch -D "cn=postfix,ou=users,ou=system,[domain]" -w postfix -b "ou=users,ou=people,[domain]" -s sub "(&(objectclass=inetOrgPerson)(mail=[mailaddr]))" delivers the correct entry. The LDAP config file looks like root@server2:/etc/postfix/ldap# cat mailbox_maps.cf server_host = localhost search_base = ou=users,ou=people,[domain] scope = sub bind = yes bind_dn = cn=postfix,ou=users,ou=system,[domain] bind_pw = postfix query_filter = (&(objectclass=inetOrgPerson)(mail=%s)) result_attribute = uid debug_level = 2 The bind_dn and bind_pw should be the same as I used above with ldapsearch. Nevertheless, calling postmap doesn't work: root@server2:/etc/postfix/ldap# postmap -q [mailaddr] ldap:/etc/postfix/ldap/mailbox_maps.cf postmap: warning: dict_ldap_lookup: /etc/postfix/ldap/mailbox_maps.cf: Search base 'ou=users,ou=people,[domain]' not found: 32: No such object If I change LDAP configuration, so that anonymous users have complete access to LDAP olcAccess: {-1}to * by * read then it works: root@server2:/etc/postfix/ldap# postmap -q [mailaddr] ldap:/etc/postfix/ldap/mailbox_maps.cf [user-id] But when I restrict this access to the postfix user: olcAccess: {-1}to * by dn="cn=postfix,ou=users,ou=system,[domain]" read by * break it doesn't work but produces the error printed above (although ldapsearch works, only postmap doesn't). Why doesn't it work when binding with a postfix DN? I think I set up the LDAP ACL for the postfix user correctly, as the ldapsearch command should prove. What can be the reason for this behaviour?

• Ideal Bacula appliance?

  - by Ricket

  I'm an intern at a small company and we (the IT department of two) manage <100 client computers and a handful of servers. Currently we're using a company's appliance to handle backup; it does a small backup every night and a full backup every weekend, and a guy comes on Wednesday to take an offsite backup drive (and gives back last week's drive to swap with it). Lately this system, mainly the appliance, has been having problems, so we are looking for an alternative. I'm researching other companies but also looking into what we might expect from trying to do this ourselves. There will undoubtedly be a large learning curve, but hey, that's what serverfault is for, right? :) So anyway I was looking at Bacula. Feature list sounds great, documentation is plentiful, but it's only software. So my question is, what is the ideal backup server to run the Bacula server software on? And not only the server but other related appliances. Our current backup appliance uses only hard drives, not tape drives. It has several plugged into it at one time, in hotswap bays on the front of the machine. I couldn't help but notice though, it's hardly more than Windows XP with hard drive bays, a PCI eSATA card (which connects to another appliance extension piece with 2 more bays), and their software. Since the company will take back their appliance if/when we cancel with them, where can I go to configure a server with these kinds of things? Maybe I'm being naive, I'm sure Dell (and any other computer company) sells them in the small business section of their website, but I wanted to make sure that there's not some other more recommended place that other companies are getting their hardware from, and that I don't need anything special for Bacula.

• Zscaler. Certs, cookies, and port 80 traffic

  - by 54's_lol

  So I work at HQ for a large company that shall remain nameless. We use Zscaler and I had to roll out a 2048 cert per zscaler's request. People around me at work dont understand the technology and think that the cert's are what is allowing internet connectivity. From my understanding(and please chime in) is the cookie located C:\Users\$$$$$$4$$\AppData\Roaming\Macromedia\Flash Player#SharedObjects\Q3JQJQJV\gateway.zscaler.net\zscaler.swf here that gets created when you provide your creds the first time you use the browser. The cert's are just simply a way of inspecting the SSL traffic as zscaler had no way of doing this before without them. They are essentially using the classic MITM attack to parse your SSL traffic. Gmail is smart enough to recognize this as you get a warning. My question is this, is there a product or service that I can use to verify my web browser when at home(I.E. off company network) isn't still getting routed to zscaler's cloud? If i do a tracert that will work fine. It's the port 80 and 443 web traffic zscaler and my company is after. I would like to verify that when I'm off their premise that my web traffic is using only my isp and the path to whatever content I'm searching for. Do the cert's i'm pushing and browser authentication do something behind the curtain that forces web traffic to get routed to zscaler? I searched quite a bit and would very much like to know if I'm ever off company scrutiny. I do know zscaler offers the service to force the scenario im asking about. Can I prove how my web traffic is getting routed? Thanks for any insight. I've been a fan for a long time and your guy's kung fu is very strong:-)
