• College Ratings via the Federal Government

  - by user9147039

  A few weeks back you might remember news about a higher education rating system proposal from the Obama administration. As I've discussed previously, political and stakeholder pressures to improve outcomes and increase transparency are stronger than ever before. The executive branch proposal is intended to make progress in this area. Quoting from the proposal itself, "The ratings will be based upon such measures as: Access, such as percentage of students receiving Pell grants; Affordability, such as average tuition, scholarships, and loan debt; and Outcomes, such as graduation and transfer rates, graduate earnings, and advanced degrees of college graduates.” This is going to be quite complex, to say the least. Most notably, higher ed is not monolithic. From community and other 2-year colleges, to small private 4-year, to professional schools, to large public research institutions…the many walks of higher ed life are, well, many. Designing a ratings system that doesn't wind up with lots of unintended consequences and collateral damage will be difficult. At best you would end up potentially tarnishing the reputation of certain institutions that were actually performing well against the metrics and outcome measures that make sense in their "context" of education. At worst you could spend a lot of time and resources designing a system that would lose credibility with its "customers". A lot of institutions I work with already have in place systems like the one described above. They are tracking completion rates, completion timeframes, transfers to other institutions, job placement, and salary information. As I talk to these institutions there are several constants worth noting: • Deciding on which metrics to measure is complicated. While employment and salary data are relatively easy to track, qualitative measures are more difficult. How do you quantify the benefit to someone who studies in one field that may not compensate him or her as well as another field but that provides huge personal fulfillment and reward is a difficult measure to quantify? • The data is available but the systems to transform the data into actual information that can be used in meaningful ways are not. Too often in higher ed information is siloed. As such, much of the data that need to be a part of a comprehensive system sit in multiple organizations, oftentimes outside the reach of core IT. • Politics and culture are big barriers. One of the areas that my team and I spend a lot of time talking about with higher ed institutions all over the world is the imperative to optimize for student success. This, like the tracking of the students’ achievement after graduation, requires a level or organizational capacity that does not currently exist. The primary barrier is the culture of "data islands" in higher ed, and the need for leadership to drive out the divisions between departments, schools, colleges, etc. and institute academy-wide analytics and data stewardship initiatives that will enable student success. • Data quality is a very big issue. So many disparate systems exist (some on premise, some "in the cloud") that keep data about "persons" using different means to identify them. Establishing a single source of truth about an individual and his or her data is difficult without some type of data quality policy and tools. Good tools actually exist but are seldom leveraged. Don't misunderstand - I think it's a great idea to drive additional transparency and accountability into the system of higher education. And not just at home, but globally. Students and parents need access to key data to make informed, responsible choices. The tools exist to not only enable this kind of information to be shared but to capture the very metrics stakeholders care most about and in a way that makes sense in the context of a given institution's "place" in the overall higher ed panoply.

• Bowing to User Experience

  As a consumer of geeky news it is hard to check my Google Reader without running into two or three posts about Apples iPad and in particular the changes to the developer guidelines which seemingly restrict developers to using Apples Xcode tool and Objective-C language for iPad apps. One of the alternatives to Objective-C affected, is MonoTouch, an option with some appeal to me as it is based on the Mono implementation of C#. Seemingly restricted is the key word here, as far as I can tell, no official announcement has been made about its fate. For more details around MonoTouch for iPhone OS, check out Miguel de Icazas post: http://tirania.org/blog/archive/2010/Apr-28.html. These restrictions have provoked some outrage as the perception is that Apple is arrogantly restricting developers freedom to create applications as they choose and perhaps unwittingly shortchanging iPhone/iPad users who wont benefit from these now never-to-be-made great applications. Apples response has mostly been to say they are concentrating on providing a certain user experience to their customers, and to do this, they insist everyone uses the tools they approve. Which isnt a surprising line of reasoning given Apple restricts the hardware used and content of the apps already. The vogue term for this approach is curated, as in a benevolent museum director selecting only the finest artifacts for display or a wise gardener arranging the plants in a garden just so. If this is what a curated experience is like it is hard to argue that consumers are not responding. My iPhone is probably the most satisfying piece of technology I own. Coming from the Razr, it really was an revolution in how the form factor, interface and user experience all tied together. While the curated approach reinvented the smart phone genre, it is easy to forget that this is not a new approach for Apple. Macbooks and Macs are Apple hardware that run Apple software. And theyve been successful, but not quite in the same way as the iPhone or iPad (based on early indications). Why not? Well a curated approach can only be wildly successful if the curator a) makes the right choices and b) offers choices that no one else has. Although its advantages are eroding, the iPhone was different from other phones, a unique, focused, touch-centric experience. The iPad is an attempt to define another category of computing. Macs and Macbooks are great devices, but are not fundamentally a different user experience than a PC, you still have windows, file folders, mouse and keyboard, and similar applications. So the big question for Apple is can they hold on to their market advantage, continuing innovating in user experience and stay on top? Or are they going be like Xerox, and the rest of the world says thank you for the windows metaphor, now let me implement that better? It will be exciting to watch, with Android already a viable competitor and Microsoft readying Windows Phone 7. And to close the loop back to the restrictions on developing for iPhone OS. At this point the main target appears to be Adobe and Adobe Flash. Apples calculation is that a) they dont need those developers or b) the developers they want will learn Apples stuff anyway. My guess is that they are correct; that as much as I like the idea of developers having more options, I am not going to buy a competitors product to spite Apple unless that product is just as usable. For a non-technical consumer, I dont know that this conversation even factors into the buying decision. If it did, wed be talking about how Microsoft is trying to retake a slice of market share from the behemoth that is Linux.Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• How to restore/change Alt+Tab behaviour/ram usage and a few other things after Ubuntu upgrade from 11.04 to 11.10?

  - by fiktor

  I use Ubuntu for programming. I recently updated it from 11.04 to 11.10. There are some things I don't like in the new version of Unity desktop interface. I don't actually know if it is hard to restore previous behavior or not, and if it is not, where should I look to do that. I know a bit of programming, but I really don't know much about Linux settings. I used to have 3-6 terminal windows and switch between them with Alt+Tab and Shift+Alt+Tab. I liked half-transparent terminal windows, since with them I could open web-page with some instruction in Firefox, press Alt+Tab and type commands in a console window, being able to recognize text on a web-page under it. Now I have problems with my usual work-style because of the following. List of "negative" changes Alt+Tab shows just one icon for all console windows. When I wait some time, it, however, shows all windows, but I don't like to wait. I prefer to remember order of windows and press Alt+Tab as many times as I need to switch to the right window. Alt+Shift+Tab to switch in reverse order doesn't work now. Console windows are not transparent any more. When I don't wait, and switch to this icon, it shows all console windows altogether. So even if they were transparent, I wouldn't be able to see anything below them (I can read something only from the window, which is directly under current one, not a few levels under). When I run a few console windows in Unity I had 740Mb used on Ubuntu 11.04, but I have 1050Mb now. The question is how to make it back to 750-. I really need my memory, since I use my computer to work with 1512Mb of data and I try to save every 10Mb possible (if it doesn't take too much of machine and, more importantly, my time). When I press "The Super key" I have a field to type the name of the program I want to run. But now it sometimes shows this field, but when I'm trying to type nothing happens. Probably, focus is not on the right field. I don't really mean to restore exactly the same behavior, but I want to make my work in Ubuntu 11.10 efficient (at least as efficient as in Ubuntu 11.04). I would be happy if there are some ways to accomplish that. What have I tried I have installed CompizConfig Settings Manager. I have read this question. However enabling "Static Application Switcher" makes Alt+Tab crazy: after enabling it It says about key-binding conflicts with "Ubuntu Unity Plugin"; "Alt+Tab" switching doesn't change, but "Shift+Alt+Tab" now works and shows all windows; Memory usage increases. I have tried turning off Ubuntu Unity Plugin, but this doesn't seem right thing to do, since it seems to turn off all menus, a lot of keystrokes and app-launcher, which usually activates with "The Super key". I have found, that window transparency can be enabled by "Opacity, Brightness and Saturation" plugin from Accessibility. However I don't know if enabling it is the right thing to do (at least it increases memory usage). Update: everything solved but #3: see my own answer below. I have made a separate question about issue #3 (transparency).

• No Customer Left Behind

  - by Kathryn Perry

  A guest post by David Vap, Group Vice President, Oracle Applications Product Development What does customer experience mean to you? Is it a strategy for your executives? A new buzz word and marketing term? A bunch of CRM technology with social software added on? For me, customer experience is a customer-centric worldview that produces a deeper understanding of your business and what it takes to achieve sustainable, differentiated success. It requires you to prioritize and examine the journey your customers are on with your brand, so you can answer the question, "How can we drive greater value for our business by delivering a better customer experience?" Businesses that embrace a customer-centric worldview understand their business at a much deeper level than most. They know who their customers are, what their value is, what they do, what they say, what they want, and ultimately what that means to their business. "Why Isn't Everyone Doing It?" We're all consumers who have our own experiences with many brands. Good or bad, some of those experiences stay with us. So viscerally we understand the concept of customer experience from the stories we share. One that stands out in my mind happened as I was preparing to leave for a 12-month job assignment in Europe. I wanted to put my cable television subscription on hold. I wasn't leaving for another vendor. I wasn't upset. I just had a situation where it made sense to put my $180 per month account on pause until I returned. Unfortunately, there was no way for this cable company to acknowledge that I was a loyal customer with a logical request - and to respond accordingly. So, ultimately, they lost my business. Research shows us that it costs six to seven times more to acquire a new customer than to retain an existing one. Heavily funding the efforts of getting new customers and underfunding the efforts of serving the needs of your existing (who are your greatest advocates) is a vicious and costly cycle. "Hey, These Guys Suck!" I love my Apple iPad because it's so easy to use. The explosion of these types of technologies, combined with new media channels, has raised our expectations and made us hyperaware of what's going on and what's available. In addition, social media has given us a megaphone to share experiences both positive and negative with greater impact. We are now an always-on culture that thrives on our ability to access, connect, and share anywhere anytime. If we don't get the service, product, or value we expect, it is easy to tell many people about it. We also can quickly learn where else to get what we want. Consumers have the power of influence and choice at a global scale. The businesses that understand this principle are able to leverage that power to their advantage. The ones that don't, suffer from it. Which camp are you in?Note: This is Part 1 in a three-part series. Stop back for Part 2 on November 19.

• Rethinking Oracle Optimizer Statistics for P6 Part 2

  - by Brian Diehl

  In the previous post (Part 1), I tried to draw some key insights about the relationship between P6 and Oracle Optimizer Statistics.  The first is that average cardinality has the greatest impact on query optimization and that the particular queries generated by P6 are more likely to use this average during calculations. The second is that these are statistics that are unlikely to change greatly over the life of the application. Ultimately, our goal is to get the best query optimization possible.  Or is it? Stability No application administrator wants to get the call at 9am that their application users cannot get there work done because everything is running slow. This is a possibility with a regularly scheduled nightly collection of statistics. It may not just be slow performance, but a complete loss of service because one or more queries are optimized poorly. Ideally, this should not be the case. The database optimizer should make better decisions with more up-to-date data. Better statistics may give incremental performance benefit. However, this benefit must be balanced against the potential cost of system down time.  It is stability that we ultimately desire and not absolute optimal performance. We do want the benefit from more accurate statistics and better query plans, but not at the risk of an unusable system. As a result, I've developed the following methodology around managing database statistics for the P6 database.  1. No Automatic Re-Gathering - The daily, weekly, or other interval of statistic gathering is unlikely to be beneficial. Quite the opposite. It is more likely to cause problems. 2. Smart Re-Gathering - The time to collect statistics is when things have changed significantly. For a new installation of P6, this is happening more often because the data is growing from a few rows to thousands and more. But for a mature system, the data is not changing significantly from week-to-week. There are times to collect statistics: New releases of the application Changes in the underlying hardware or software versions (ex. new Oracle RDBMS version) When additional user groups are added. The new groups may use the software in significantly different ways. After significant changes in the data. This may be monthly, quarterly or yearly.  3. Always Test - If you take away one thing from this post, it would be to always have a plan to test after changing statistics. In reality, statistics can be collected as often as you desire provided there are tests in place to verify that performance is the same or better. These might be automated tests or simply a manual script of application functions. 4. Have a Way Out - Never change the statistics without a way to return to the previous set. Think of the statistics as one part of the overall application code that also includes the source code--both application and RDBMS. It would be foolish to change to the new code without a way to get back to the previous version. In the final post, I will talk about the actual script I created for P6 PMDB and possible future direction for managing query performance.

• Can someone explain the true landscape of Rails vs PHP deployment, particularly within the context of Reseller-based web hosting (e.g., Hostgator)?

  - by rcd

  Currently, I have a reseller account with the company HostGator. I design websites, which up until now have occasionally been wrapped in Wordpress CMSs and the like (PHP applications). I then sell hosting (of the site I've designed) to the client, which is pretty simple, in that I can simply click a button and add a new shared hosting account/site with whatever settings I want. Furthermore, I then utilize WHMCS to automate billing and account management. It's a nice package and pretty simple. I pay something like $25 a month, and can sell a hundred accounts under this (because my clients bandwidth requirements are low). Now I am finding the need to develop more customized applications, including a minimalist CMS and several proprietary things. I soon anticipate developing these apps for clients as well. Thus, I've spent the past few months learning Rails, and it's coming along well now. The thing that has nagged at me all along, though, is the deployment issue. I can't wrap my brain around it. It seems like all of the popular options (Heroku, etc) have nice automation with git and are set up in the "Rails Way". I get that (sort of). But it's terribly expensive... a single dyno, a helper, and the cheapest database (which they say is mainly suitable for testing) that isn't limited to 5MB runs $51. This is for ONE app!!! Throw in a "production" DB and you're over $200. This is like... the same prices as getting a server somewhere, right? Meanwhile, going back to what I guess is a "traditional" hosting environment with Hostgator, their server only has Ruby 1.8.7 and Rails 2.3.5... No Rails 3. AND, no Passenger (not that I really understand the difference in CGI or mod_rails or whatever, but they say Passenger is the simplest). So I'm to understand that if I build an app in Rails 3, it won't run at all on this host? But damn, I already have these accounts under my reseller account there, all running static html and/or PHP stuff, right? So what now? How do I get all of this under one simple (and affordable) roof? Forgive my ignorance, but I just don't get it. Managing a VPS is cool and all, but entails learning server admin stuff and security... And it's expensive. I get that a shared and/or reseller "server-based" (forgive the terminology) may be inadequate for large-scale apps that use a lot of bandwidth... But what about for those of us who are building real (but small and low bandwidth) apps (with Rails) and who want to deploy them simply, cheaply, using the same conceptual approach as PHP? Even after learning all of this Ruby and Rails stuff for months, I'm questioning whether it's worth it when it comes to deployment. I want to build a small app, upload it to my home directory on a shared server account, and just make it run. Why should that be so hard? Am I just choosing the wrong language/framework? Forgive my ignorance in the subject; these questions are not rhetorical; just trying to learn here. So: 1) I'd appreciate if someone could give me a good rundown of how to understand deployment in Rails vs. PHP. 2) I'd appreciate if someone could address my issue with running a hosting/web business around reseller hosting (Hostgator) while also being able to host Rails apps. Can it be done? And how can a company like Hostgator completely ignore what's current in Rails/Ruby? Thanks.

• Best way to process a queue in C# (PDF treatment)

  - by Bartdude

  First of all let me expose what I would like to do : I already dispose of a long-time running webapp developed in ASP.NET (C#) 2.0. In this app, users can upload standard PDF files (text+pics). The app is running in production on a Windows Server 2003 and has a dedicated database server (SQL server 2008) also running Windows Server 2003. I myself am a quite experienced web developer, but never actually programmed anything non-web (or at least nothing serious). I plan on adding a functionality to the webapp for which I would need a jpg snapshot of each page of the PDF. Creating these "thumbnails" isn't the big deal as such, I already do it inside my webapp using ghostscript. I've only done it on 1 page documents for now though, and the new functionality will need to process bigger documents. In order for this process to be transparent aswell for the admins as the final users, I would like to implement some kind of queue to delay the processing of the thumbnails. There again, no problem to create the queue, it will consist of records in a table, with enough info to find the pdf document back. Then I will need to process this queue, and that's were my interrogations start. Obviously the best solution to process it isn't an ASP script or so, so I will have to get out of my known environment. No problem, but I have no idea which direction to go. Therefore, a few questions : What should I develop ? I presumably need something that is "standby" on the server, runs when needed, then returns to idle state until further notice.Should I be looking into Windows service ? Is there another more appropriate type of project ? Depending on the first answer, what will be the approach ? Should I have somehow SQL server "tell" the program/service/... to process the queue, or should I have that program/service/... periodically check the state of the queue and treat new items. In both case, which functionality can I use ? we're not talking about hundreds of PDF a day (max 50 maybe), I can totally afford to treat the queue 1 item at a time. Can you confirm I don't have to look much further on threads and so ? (I found a lot of answers talking about threads in queue treatment, but it looks quite overkill for my needs) Maybe linked to the previous question : what about concurrent call to the program, whatever it is ? Let's suppose it is currently running, and a new record comes in the queue, what should be the behaviour ? I don't need much detailed answers and would already be happy with answers like "You can do the processing with a service, and yes it's possible to have sqlserver on machine A trigger a service start on machine B" or "You have to develop xxx and then use the scheduler to run it every xxx minutes". I don't mind reading articles and so, but I can hardly afford to spend too much time learning stuff to finally realize I went the wrong way for this project, so basically I'm trying to narrow down the scope of matters I need to investigate. Thanks for reading me, I hope I'll find some helping hands on here :-)

• Is changing my job now a wise decision? [closed]

  - by FlaminPhoenix

  First a little background about myself. I am a javascript programmer with 3.8 years of experience. I joined my current company a year and 3 months ago, and I was recruited as a javascript programmer. I was under the impression I was a programmer in a programming team but this was not the case. No one else except me and my manager knows anything about programming in my team. The other two teammates, copy paste stuff from websites into excel sheets. I was told I was being recruited for a new project, and it was true. The only problem was that the server side language they were using was PHP. They were using a popular library with PHP, and I had never worked with PHP before. Nevertheless, I learnt it well enough to get things working, and received high praise from my boss's boss on whichever project I worked on. Words like "wow" , "This looks great, the clients gonna be impressed with this." were sprinkled every now and then on reviewing my work. They even managed to sell my work to a couple of clients and as I understand, both of my projects are going to fetch them a pretty buck. The problem: I was asked to move into a project which my manager was handling. I asked them for training on the project which never came, and sure enough I couldnt complete my first task on the new project without shortcomings. I told my manager there were things I didnt know how to get done in the new project due to lack of training. His project had 0 documentation. I was told he would "take care" of everything relating to those shortcomings. In the meantime, I was asked to switch to another project. My manager made the necessary changes and later told me that the build had "broken" on the production server and that I needed to "test" my changes before saying things were done. I never deployed it on the production server. He did. I never saw / had the opportunity to see the final build before it went to production. He called me for a separate meeting and started pointing fingers at me, but I took full responsibility even if I didnt have to. He later on got on a call with his boss, in my presence, and gave him the impression that it was all my fault. I did not confront him about this so far. I have worked late / done overtime without them asking a lot, but last week, I just got home from work, and I got calls asking me to solve an issue which till then they had kept quiet about even though they were informed about it. I asked my manager why I hadnt been tasked with this when I was in office. He started telling me which statements to put where, as if to mock me, and that this "is hardly an overtime issue" and this pissed me off. Also, during the previous meeting, he was constantly talking highly about his work, at the same time trying to demean mine. In the meantime, I have attended an interview with another MNC, and the interviewers there were fully respectful of my decision to leave my current company. Its a software company, so I can expect my colleagues to know a lot more than me. Im told I can expect their offer anytime this week. My questions: Is my anger towards my manager justified? While leaving, do I tell him that its because of his actions that Im leaving? Do I erupt in anger and tell him that he shouldnt have put the blame on me since he was the one doing the deployment? This is going to be my second resignation to this company. The first time I wanted to resign, I was asked to stay back and my manager promised a lot of changes, a couple of which were made. How do I keep myself from getting into such situations with my employers in the future?

• My Favorite Free Windows Phone Twitter App

  - by Tim Murphy

  Windows Phone 7 has been out for about two years now.  In that time I have switched back and forth with different free Twitter apps.  Mostly the has been because someone has mentioned one or another that they like.  I figured I would give a quick run down of what I felt were the pros and cons of each.  These are only the ones that I have used and your mileage may vary.  So here we go. WP7 Built-In Twitter Functionality While it is great that Microsoft put this functionality in, it is extremely limited in usefulness.  Some apps leverage it to allow you to share pictures or information they contain.  In all though, I don’t use it unless it is the quickest way to get something out. Official Twitter App The official Twitter app isn’t a very big step up from the phone functionality.  It gives you a better timeline view and better attachment handling, but it makes you bounce to a browser page to see images that are linked to a tweet. TweetCaster This was my main Twitter app for quite a while.  It is the only one with InstaPaper integration so that you can save you a tweet and review it later.  My main problem is that it crashes too much when it can’t find a connection.  It also only previews yfrog and twitpic images and only once you go to the detail of a tweet.  Other than that it is a solid Twitter client. moTweets This is my current favorite. It has nice image display in your timeline which I have not seen on any of the other apps.  There are two modes that you can use with this app.  The first is standard to most Twitter apps that allows you to navigate to a tweet and do the usual operations.  The second is what they call Quick Buttons.  In this case you do not see the content of the tweet but go straight to the let’s get something done stage.  It is an interesting take.  I do miss the Instapaper integration and it has a tendency to show a blank timeline list once in a while after you view detail entry.  If you scroll the list it restore your timeline, but you lose you place and are put to the first entry. Seesmic I am not very fond of this app.  The first thing is that it makes you pick a “Space” when you enter the app.  This is really “which account do you want to see”.  On top of that it does not show who retweeted an entry in your timeline and then only tells you how many people RT the post when you look at the detail.  There is a Speak feature that will read you a single tweet, but you have to navigate to the tweet and then to a menu to make it work.  We will have to see if this gets better with the features in Windows Phone 8.  Other than that it is another basic feature app.  Summary In the end I am sticking with moTweets.  I would appreciate it if they added the Instapaper capability and fixed the one bug.  If they did that I would be really happy with the product. del.icio.us Tags: Twitter,Windows Phone 7,WP7,TweetCaster,moTweets,Seesmic

• 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). Original Post I'm getting this error in the event viewer: IISMANAGER_ERROR_LOADING_PROVIDER_TYPE IIS Manager could not load type 'Web.Management.PHP.PHPProvider, Web.Management.PHP, Version=1.2.0.0, Culture=neutral, PublicKeyToken=8175de49a9aec91d' for module provider 'PHP' that is declared in %windir%\system32\inetsrv\config\administration.config.

• tightvnc authentication failure

  - by broiyan

  When I run a tightvnc client to establish a VNC session I sometimes receive an error message that suggests there are repeated failed VNC login attempts or a brute force attack. The message dialog title is "unsupported security type" and the text content is "too many authentication failures, try another connection? yes/no". This problem goes away if I reboot the Ubuntu server and reload the VNC server program and try again. From that point, it will work for multiple VNC sessions. My VNC sessions are typically about 20 minutes. At some time in the future, the problem may recur so it seems correlated to the time the server has been up or the time tightvnc has been loaded. Typically it takes only a day or so before the problem comes back. I am using tightvnc 1.3 on an server running Ubuntu 12.04. The version of vncserver is rather dated because that seems to be all that is available from tightvnc for linux servers. On the client side I use the newest Java-based VNC client (version 2.5) for both Windows access and Ubuntu access. All my VNC sessions are via SSH. I am the only user and I will typically use only the same client computer. How can I stop this problem from recurring? Edit I found the log file. This is a small excerpt of what I am seeing. Essentially, various IPs, not my own, are attempting to connect. What is the practical solution for this? 05/06/12 20:07:32 Got connection from client 69.194.204.90 05/06/12 20:07:32 Non-standard protocol version 3.4, using 3.3 instead 05/06/12 20:07:32 Too many authentication failures - client rejected 05/06/12 20:07:32 Client 69.194.204.90 gone 05/06/12 20:07:32 Statistics: 05/06/12 20:07:32 framebuffer updates 0, rectangles 0, bytes 0 05/06/12 20:24:56 Got connection from client 79.161.16.40 05/06/12 20:24:56 Non-standard protocol version 3.4, using 3.3 instead 05/06/12 20:24:56 Too many authentication failures - client rejected 05/06/12 20:24:56 Client 79.161.16.40 gone 05/06/12 20:24:56 Statistics: 05/06/12 20:24:56 framebuffer updates 0, rectangles 0, bytes 0 05/06/12 20:29:27 Got connection from client 109.230.246.54 05/06/12 20:29:27 Non-standard protocol version 3.4, using 3.3 instead 05/06/12 20:29:28 rfbVncAuthProcessResponse: authentication failed from 109.230.246.54 05/06/12 20:29:28 Client 109.230.246.54 gone 05/06/12 20:29:28 Statistics: 05/06/12 20:29:28 framebuffer updates 0, rectangles 0, bytes 0

• Windows Server 2012 Branchcache vs. DFS-R

  - by TheCleaner

  Warning, subjective question ahead! But hopefully a good one that won't get closed. SCENARIO: I have a branch office that currently has no on-premise server. They access everything including a DC across a 12Mbps WAN link (MPLS). The link isn't saturated, averaging around 20% utilization. The circuit is very stable and has a high SLA and excellent uptime. However, large file transfers (mainly reads, not writes) from the file server across the WAN can be slow. We don't currently utilize DFS. RESEARCH DONE: I'm aware of WAN acceleration, using either dedicated hardware (Riverbed) or a dedicated software VM (Silver Peak) for example. But the pricing is outside of our current budget and the need isn't quite there yet from our perspective (since the issue is mainly in a "pull" scenario not necessarily push/pull). I'm mainly looking at deploying a Windows server at this branch office and either utilizing DFS-R or BranchCache. Looking at a table comparison and assuming we are looking at a "hosted branchcache server" and not simply distributed: It would appear there are benefits to both, even if both are "hosted" on a server. QUESTIONS I ACTUALLY HAVE: In what scenarios do each of these techs shine and where do you choose one over the other? Looking at a hosted Branchcache server, can you set "pre-fetching" of certain folders/files on the central file server so that they are immediately accessible locally at the branch? Do you have to do this on a schedule (if it is possible)? Looking at DFS-R my concern (and apparently solved with 3rd party apps) is file locking and making sure the file gets updated properly during a write operation (ie, making sure if both copies are accessed and both are written to, which file takes precedence and what happens to the changes?). Ideal it would seem would be to lock any alternate replicas of the data, but is it really that big of an issue? Does Branchcache lock the central file for editing? Does branchcache only transmit the deltas back to the central file of what has changed? Would either technology be ill advised if the branch office server was going to be utilized as a domain controller as well?

• Why is there a /etc/init.d/mysql file on this Slackware machine? How could it have gotten there?

  - by jasonspiro

  A client of my IT-consulting service owns a web-development shop. He's been having problems with a Slackware 12.0 server running MySQL 5.0.67. The machine was set up by the client's sysadmin, who left on bad terms. My client no longer employs a sysadmin. As far as I can tell, the only copy of MySQL that's installed is the one described in /var/log/packages/mysql-5.0.67-i486-1: PACKAGE NAME: mysql-5.0.67-i486-1 COMPRESSED PACKAGE SIZE: 16828 K UNCOMPRESSED PACKAGE SIZE: 33840 K PACKAGE LOCATION: /var/slapt-get/archives/./slackware/ap/mysql-5.0.67-i486-1.tgz PACKAGE DESCRIPTION: mysql: mysql (SQL-based relational database server) mysql: mysql: MySQL is a fast, multi-threaded, multi-user, and robust SQL mysql: (Structured Query Language) database server.

P.S. This question is far from perfect. Please feel free to edit it.

• SCVMM 2012 R2 - Installing Virtual Switch Fails with Error 2916

  - by Brian M.

  So I've been attempting to teach myself SCVMM 2012 and Hyper-V Server 2012 R2, and I seem to have hit a snag. I've connected my Hyper-V Host to SCVMM 2012 successfully, and created a logical network, logical switch, and uplink port profile (which I essentially blew through with the default settings). However when I attempt to create a virtual switch on my Hyper-V host, I run into an issue. The job will use my logical network settings I created to configure the virtual switch, but when it tries to apply it to the host, it stalls and eventually fails with the following error: Error (2916) VMM is unable to complete the request. The connection to the agent vmhost1.test.loc was lost. WinRM: URL: [h**p://vmhost1.test.loc:5985], Verb: [GET], Resource: [h**p://schemas.microsoft.com/wbem/wsman/1/wmi/root/virtualization/v2/Msvm_ConcreteJob?InstanceID=2F401A71-14A2-4636-9B3E-10C0EE942D33] Unknown error (0x80338126) Recommended Action Ensure that the Windows Remote Management (WinRM) service and the VMM agent are installed and running and that a firewall is not blocking HTTP/HTTPS traffic. Ensure that VMM server is able to communicate with econ-hyperv2.econ.loc over WinRM by successfully running the following command: winrm id –r:vmhost1.test.loc This problem can also be caused by a Windows Management Instrumentation (WMI) service crash. If the server is running Windows Server 2008 R2, ensure that KB 982293 (h**p://support.microsoft.com/kb/982293) is installed on it. If the error persists, restart vmhost1.test.loc and then try the operation again. Refer to h**p://support.microsoft.com/kb/2742275 for more details. I restarted the server, and upon booting am greeted with a message stating "No active network adapters found." I load up powershell and run "Get-NetAdapter -IncludeHidden" to see what's going on, and get the following: Name InterfaceDescription ifIndex Status ---- -------------------- ------- ----- Local Area Connection* 5 WAN Miniport (PPPOE) 6 Di...

Does anybody have any ideas? Much appreciated!

• Installing WindowsAuthentication breaks authentication / web.config?

  - by Ian Quigley

  I have a clean Windows 2008 R2 box (on a VM) and have installed IIS 7.5 with default options. I then copied a website to it (from Windows 7, IIS 7) and after a little tweaking the website is working fine. The website is currently using and working with Anonymous Authentication. I have gone back to the Windows Components/Sever Manager, Roles - Security and ticked and installed Windows Authentication. When I check my server in IIS (top level above sites) - Authentication, I see Anonymous Authentication (enabled) ASP.NET Impersonation (disabled) Forms Authentication (disbaled) Windows Authentication (enabled) When I check my default website - Authentication, I see as above but "Retrieving status" and an error dialog saying There was an error while performing this operation. Details: Filename c:\inetpub\wwwroot\screwturnwiki\web.config Line number: 96 Error: This configuration section cannot be used in this path. This happens when the section is being locked at the parent level. Locking is either by default (overriderModeDefault="Deny"), or set explicity by a location tag with overrideMode="Deny" or the legacy allowOverride="False". I have tried hand editing the web.config with no success. (How to use locking in IIS7 Configuration) UN-installing Windows Authentication happily returns my site to working with Anonymous Authentication, and allows me to enable/disable these three options. FYI. I am using ScrewTurnWiki with the Active Directory plug in. It all works fine under Windows 7 IIS 7 locally (has been for months) Web.Config <system.webServer> (edit) <handlers> ( deleted removes/adds ) </handlers> <security> <authentication> 96: <windowsAuthentication enabled="true" useKernelMode="true"> <extendedProtection tokenChecking="Allow" /> <providers> <clear /> <add value="NTLM" /> <add value="Negotiate" /> </providers> </windowsAuthentication> </authentication> </security>

• Query total page count via SNMP HP Laserjet

  - by Tim

  I was asked to get hold of the total pages counts for the 100+ printers we have at work. All of them are HP Laser or Business Jets of some description and the vast majority are connected via some form of HP JetDirect network card/switch. After many hours of typing in IP addresses and copying and pasting the relevant figure in to Excel I have now been asked to do this on a weekly basis. This led me to think there must be an easier way, as an IT professional I can surely work out some time saving method to solve this issue. Suffice it to say I do not feel very professional now after a day or so of trying to make SNMP work for me! From what I understand the first thing is to enable SNMP on the printer. Done. Next I would need something to query the SNMP bit. I decided to go open source and free and someone here recommended net-snmp as a decent tool (I would like to have just added the printers as nodes in SolarWinds but we are somewhat tight on licences apparently). Next I need the name of the MIB. For this I believe the HP-LASERJET-COMMON-MIB has the correct information in it. Downloaded this and added to net-snmp. Now I need the OID which I believe after much scouring is printed-media-simplex-count (we have no duplex printers, that we are interested in at least). Running the following command yields the following demoralising output: snmpget -v 2c -c public 10.168.5.1 HP-LASERJET-COMMON-MIB:.1.3.6.1.2.1.1.16.1.1.1 (the OID was derived from running: snmptranslate -IR -On printed-media-simplex-count Unlinked OID in HP-LASERJET-COMMON-MIB: hp ::= { enterprises 11 } Undefined identifier: enterprises near line 3 of C:/usr/share/snmp/mibs/HP-LASER JET-COMMON-MIB..txt .1.3.6.1.2.1.1.16.1.1.1 ) Unlinked OID in HP-LASERJET-COMMON-MIB: hp ::= { enterprises 11 } Undefined identifier: enterprises near line 3 of C:/usr/share/snmp/mibs/HP-LASER JET-COMMON-MIB..txt HP-LASERJET-COMMON-MIB:.1.3.6.1.2.1.1.16.1.1.1: Am I barking up the wrong tree completely with this? My aim was to script it all to output to a file for all the IP addresses of the printers and then plonk that in Excel for my lords and masters to digest at their leisure. I have a feeling I am using either the wrong MIB or the wrong OID from said MIB (or both). Does anyone have any pointers on this for me? Or should I give up and go back to navigationg each printers web page individually (hoping not).

• Networking issues with Linux server (CentOS 5.3)

  - by sxanness

  I have a Linux server hosting our bug tracking software (CentOS 5.2 Kernel 2.6.18-128.4.1.el5) that I have having some strange network problems with. The machine is configured with two NICS, one for the public interface and the other for our server back end network. The problem is that after doing a service network restart I can ping the public interface and it sends anywhere from 200-500 ICMP packets and then all of a sudden I start getting a request timed out error. Strange but as soon as I connect to the private interface the ping starts working again to the public interface. I clearly have a routing issue somewhere. I have a Juniper Router with the following configuration. Interface 0/0 -- Connect subnet to the ISP at our co-location Interface 0/2 -- For our DRAC network Interface 0/3 -- The Server-backend network (plugs directly into a switch that feeds to all the NICs that are on the 10.3.20.x network. Interface 0/4 -- Plugs directly into another switch that feeds our public interfaces, that interface as all the gateways from our public ip rangs as secondary IP addresses. I hope that someone can ask the right questions that can lead me to check things and figure out what is going on. Has anyone had similar problems and what kind of things should I be checking?

• Watchguard Firewall - Issues with SSLVPN

  - by David W

  I have a client who has a WatchGuard XTM 23 device on site as their primary firewall. I just upgraded its firmware a couple days ago to the latest version for that series, 11.6.6. The problem is that I haven't successfully been able to setup a VPN connection for them. Using the instructions at http://www.watchguard.com/help/docs/webui/11_XTM/en-US/index.html#en-US/mvpn/ssl/configure_fb_for_mvpn_ssl_c.html, I'm trying to setup a VPN with SSL connection: From the firewall web GUI / Dashboard, I go to VPN - Mobile VPN with SSL, I enable it, add the organization's public IP address to which the firewall is connected. I've setup a group in Active Directory named "SSLVPN-Users", verified that the WatchGuard box can talk to the Active Directory Server, and added myself to that group. I then downloaded the WatchGuard Mobile VPN with SSL client onto my own Windows 7 machine, walked to the client's 2nd building across the street (which has a different public internet connection), and tried to connect to the VPN. When I do try to connect with the client, I get the following errors: 2013-06-24T15:41:32.119 Launching WatchGuard Mobile VPN with SSL client. Version 11.6.0 (Build 343814) Built:Jun 13 2012 01:42:55 2013-06-24T15:41:37.595 Requesting client configuration from 184.174.143.176:443 2013-06-24T15:41:50.106 FAILED:Cannot perform http request, timeout 12002 2013-06-24T15:41:50.106 failed to get domain name I discovered today the Firebox System Manager, and its "Traffic Monitor" which gives current log information (refreshes every 5 seconds). Unfortunately, it doesn't look like the client has setup any sort of WatchGuard / Firebox logging server, so actually recording server-side logs to file hasn't been done. I can work on implementing that if I need to. I noticed that if I try to ping the client's public IP address from an outside source, I don't get a response back (unless I added a policy into the firewall to allow ICMP traffic from "External", which I successfully did a few seconds ago for testing purposes - that rule has since been reverted to not respond to external ping requests). There's a policy in the firewall for allowing SSLVPN Traffic authentication requests coming from any external source TO the Firebox, and then to do the authentication / actually allow the VPN traffic, there's a policy allowing traffic for anyone in the SSLVPN-Users group to flow between that user and the inside network. So my questions are: Has anyone seen these errors before from the Watchguard VPN Client, and/or do you have any suggestions on how I can resolve that error? If I need to setup logging server to grab the firewall logs (in order to further troubleshoot this issue), how complicated a task is that and does it require a lot of system resources? The organization I'm consulting with only has 1 server and not a lot of resources or technical know-how.

• PXE-E32 TFTP Open Timeout While Attempting to PXE Boot from Windows Deployment Services

  - by bschafer

  I'm running Windows Deployment Services on Windows Server 2008 R2 on top of an ESX 4.0 box. This is the only function of this VM instance, although it had previously functioned as an AD Domain Controller. My DHCP server is running on our primary Domain Controller, which is also Server 2008 R2, but running on metal. Everything was working perfectly until we recently had our backup generator fail during a power outage, causing all of our servers and networking equipment to lose power for a period of time. When we brought all of our equipment back up, everything was working as expected except for WDS. Our network is split up into several different vlans. Now, depending on which vlan the client computer is on, it's behaving differently when attempting to PXE boot into WDS. Our servers are located on the 10.55.x.x vlan, which, due to the nature of it, has no DHCP server active in it. The first computer we plugged in happened to be in the 10.99.x.x vlan, which is supposed to be reserved for network management devices (i.e. switches), but we've been using it occasionally otherwise. That computer gave us PXE-E11 ARP Timeout errors. When we moved to a different computer on the 10.19.x.x vlan (for general purpose use), it finally gets an IP from DHCP, but it presents us with a very stumping PXE-E32 TFTP Open Timeout error. Before the power outage, it didn't matter which vlan a device was on; it would PXE boot and image just fine. I've made no changes to anything server-side. Everything is configured exactly the same way it was on my WDS and DHCP servers as before the power outage. I've tried several different computers, including different models. All of this, combined with the quirky behavior depending on the vlan, makes me think something went wrong in one or more of our switches, probably because of the power outage. Unfortunately, I'm no network guy, and I know very little about how to configure our switches properly. Is this an issue with switches, etc? If so, how can I fix it? Is there some magical option I'm not aware of? Does anybody out there have any hunches? I've pretty much exhausted my ideas. Our main switch is an HP Procurve 5406. We also have 3x HP Procurve 4208 switches. The ESX Server is an HP ProLiant DL380 G6. The WDS VM is currently using the VMXNET3 network adaptor, but we've also tried the E1000 adaptor.

• Macbook Pro - Randomly sleeps and won't wake up

  - by James

  All, I have a Macbook Pro 13" (mid 2009) that has had a long time issues which seems to be getting worse. Occasionally, I will go to wake the computer with the keyboard and can't wake it. The HDD spins up, the light on the front of the computer stops blinking, but as soon as it seems like the display should light up, the HDD stops and the light begins blinking again. More rarely, the computer will suddenly sleep while I am using it and then enters the same sleep loop. The only way to resume working on the computer is to wait. Doing a hard restart just puts it right back into the 'sleep loop.' Here is an excerpt from kernel.log showing the laptops apparent narcolepsy: Jun 5 22:20:40 james-hales-macbook-pro kernel[0]: Wake reason: OHC1 Jun 5 22:20:40 james-hales-macbook-pro kernel[0]: Previous Sleep Cause: 5 Jun 5 22:20:40 james-hales-macbook-pro kernel[0]: The USB device Apple Internal Keyboard / Trackpad (Port 6 of Hub at 0x4000000) may have caused a wake by issuing a remote wakeup (2) Jun 5 22:20:40 james-hales-macbook-pro kernel[0]: HID tickle 31 ms Jun 5 22:20:41 james-hales-macbook-pro kernel[0]: 00000000 00000020 NVEthernet::setLinkStatus - not Active Jun 5 22:20:45 james-hales-macbook-pro kernel[0]: MacAuthEvent en1 Auth result for: 20:4e:7f:48:c0:ef MAC AUTH succeeded Jun 5 22:20:45 james-hales-macbook-pro kernel[0]: wlEvent: en1 en1 Link UP Jun 5 22:20:45 james-hales-macbook-pro kernel[0]: AirPort: Link Up on en1 Jun 5 22:20:45 james-hales-macbook-pro kernel[0]: en1: BSSID changed to 20:4e:7f:48:c0:ef Jun 5 22:20:46 james-hales-macbook-pro kernel[0]: AirPort: RSN handshake complete on en1 Jun 5 22:20:48 james-hales-macbook-pro kernel[0]: 00000000 00000020 NVEthernet::setLinkStatus - not Active Jun 5 22:20:54 james-hales-macbook-pro kernel[0]: Jun 5 22:20:55 james-hales-macbook-pro kernel[0]: Wake reason: OHC1 Jun 5 22:20:55 james-hales-macbook-pro kernel[0]: Previous Sleep Cause: 5 Jun 5 22:20:55 james-hales-macbook-pro kernel[0]: The USB device Apple Internal Keyboard / Trackpad (Port 6 of Hub at 0x4000000) may have caused a wake by issuing a remote wakeup (2) Jun 5 22:20:55 james-hales-macbook-pro kernel[0]: wlEvent: en1 en1 Link DOWN Jun 5 22:20:55 james-hales-macbook-pro kernel[0]: AirPort: Link Down on en1.

• Can't install Perl DBD module on Ubuntu (for Bugzilla)

  - by Mara

  Trying to install bugzilla-4.2.2 on Ubuntu 12.04. When I run checksetup.pl I get the following error: YOU MUST RUN ONE OF THE FOLLOWING COMMANDS (depending on which database you use): PostgreSQL: /usr/bin/perl install-module.pl DBD::Pg MySQL: /usr/bin/perl install-module.pl DBD::mysql SQLite: /usr/bin/perl install-module.pl DBD::SQLite Oracle: /usr/bin/perl install-module.pl DBD::Oracle To attempt an automatic install of every required and optional module with one command, do: /usr/bin/perl install-module.pl --all I have installed MySQL via XAMPP so I run: /urs/bin/perl install-module.pl DBD::mysql And get the following error: perl Makefile.PL --testuser=username Can't exec "mysql_config": No such file or directory at Makefile.PL line 479.

Falling back to other methods to determine prerequisites So then I tried checksetup.pl's suggestion and ran: /usr/bin/perl install-module.pl --all And it seems to have installed DBD::SQLite without any problems, but again I see a warning that says it's skipping tests because of notest pragma. When I re-run checksetup.pl It shows 3 of the 4 original DB drivers in the "not found" list: PostgreSQL: /usr/bin/perl install-module.pl DBD::Pg MySQL: /usr/bin/perl install-module.pl DBD::mysql Oracle: /usr/bin/perl install-module.pl DBD::Oracle So running it with --all seems to have installed the SQLite driver without any problems, but for some reason I can't seem to install the MySQL driver. Again I need MySQL because thats what XAMPP uses and because I prefer MySQL regardless. I have a feeling it has something to do with this notest pragma error. Any ideas? Thanks in advance!

• Partitioning recommendations for a Proxmox VM Server (OpenVZ)

  - by luison

  We are new to virtualization and we are planning to turn our online server into a virualized one, mainly for maintenance, backup and recovery improvements. Initially we would only have one real virtual system with load plus 1-3 copys for testing and recovering and maybe a small centralized syslog virtual machine. We would like, if possible the host machine to include an iptables plus rsync to back up to other machines and some other global security systems. Due to this and the offerings of our hosting supplier we are mainly considering Proxmox for its simplicity (we like the idea of its web admin panel) and as I also understand that the container approach of OpenVMZ systems may fit well resource wise with our setup. The base system comes with debian so we can personalise it to our requirements. Proxmox installations default installs an LVM partition for the VMs. Our doubts are with the fact of what would be the best partition structure for this considering that: we would like to have a mirror of the root partition we could boot from if required (our provider supports booting the system from another partition via control panel) we ideally would like to have a partition that could be shared among the VM systems. We still don't know if this is possible directly with OpenVMZ containers, otherwise we are considering doing this by sharing it via NFS on the host machine. we want to use the backup system available on the proxmox host administrator to programme VMs backups and then rsync it to another machine. With this based on a Linux Raid of aprox (750Gb) we are considering something like: ext3_1/ - (20Gb) ext3_2/bak_root - (20Gb) mostly unmounted, root partition sync LVM_1 /var/lib/vz - (390Gb) partition for virtual images LVM_2 /shared_data - (30Gb) LVM_3 /backups - (300Gb) where all backups would be allocated Our initial tests with Proxmox seem to have issues with snapshots backups like this, perhaps caused by the fact that they can not be done to another LVM partition (error: command 'lvcreate --size 1024M --snapshot --name vzsnap-ns204084.XXX.net-0 /dev/pve/LV' failed with exit code 5) in which case we might have to use a standart ext3 partition (but unsure if we can do this with the 4 primary partition limitations). Does this makes more or less sense? Would it be mad to for example write VMs /var/logs to a NFS mounted partition (on the host system)? Are their any other easier ways to mount host system partitions (or folders) to the VMs?
