• SQLAuthority News – I am Presenting 2 Sessions at TechEd India

  - by pinaldave

  TechED is the event which I am always excited about. It is one of the largest technology in India. Microsoft Tech Ed India 2011 is the premier technical education and networking event for tech professionals interested in learning, connecting and exploring a broad set of current and soon-to-be released Microsoft technologies, tools, platforms and services. I am going to speak at the TechED on two very interesting and advanced subjects. Venue: The LaLiT Ashok Kumara Krupa High Grounds Bangalore – 560001, Karnataka, India Sessions Date: March 25, 2011 Understanding SQL Server Behavioral Pattern – SQL Server Extended Events Date and Time: March 25, 2011 12:00 PM to 01:00 PM History repeats itself! SQL Server 2008 has introduced a very powerful, yet very minimal reoccurring feature called Extended Events. This advanced session will teach experienced administrators’ capabilities that were not possible before. From T-SQL error to CPU bottleneck, error login to deadlocks –Extended Event can detect it for you. Understanding the pattern of events can prevent future mistakes. SQL Server Waits and Queues – Your Gateway to Perf. Troubleshooting Date and Time: March 25, 2011 04:15 PM to 05:15 PM Just like a horoscope, SQL Server Waits and Queues can reveal your past, explain your present and predict your future. SQL Server Performance Tuning uses the Waits and Queues as a proven method to identify the best opportunities to improve performance. A glance at Wait Types can tell where there is a bottleneck. Learn how to identify bottlenecks and potential resolutions in this fast paced, advanced performance tuning session. My session will be on the third day of the event and I am very sure that everybody will be in groove to learn new interesting subjects. I will have few give-away during and at the end of the session. I will not tell you what I will have but it will be for sure something you will love to have. Please make a point and reserve above time slots to attend my session.

• Frustrated where I am, but not sure where to go with my career [closed]

  - by Tom Pickles

  I work (3 years now) as a lead developer for a team developing internal tools and websites for a customer account within large outsourcing company. I'm a self taught programmer and my previous incarnation was a 3rd line support guy, so I have a solid infrastructure knowledge. We use VB.Net/MSSQL/SSIS/SSRS ASP.NET (nTier) in house and I have about 8 years coding experience. Without going into too much detail, my boss is very ambitious and uses our team as his footing to get up the ladder. I've been in the team from the start and the only new dev's we have brought in have been people with a bit of VBA/VBScript experience, much to my chagrin, to bolster his empire. It's been a lot of hard work to bring them up to a standard, but there's still a lot for them to learn. This makes my life stressful as I always get the high profile/complex project work to do as other's simply cannot do it, or it'd take them twice/three times longer to do it. My boss is always seeking stuff for us to build for people who haven't asked for it, which usually get's thrown to me as I have the most experience and can pick new API's (etc) up quicker. He doesn't give us proper requirements, we don't get time to design properly before we code, he wants us to throw something (quick and dirty as he calls it) together so we can get it out ASAP. I take pride in my work so I like to do it properly, make my code clean, maintainable etc, and I train the other guys in the team to do the same. But, we always fall on our faces. The customer we drop the apps on say it doesn't do what they need (due to few requirements), or my boss doesn't like it/changes the spec, so we have to rework it, it get's drawn out, and it makes us and me look and feel like fools. We then get accused by boss of not being reactive enough to change. I've had enough. In order to get my skills and knowledge gap's filled, I've been reading Code Complete 2nd Ed (McConnell) and the Head First Design Patterns books. I'm forcing myself to move into C# from VB at home to broaden my horizons. I'm not sure where to go from here. I don't want to code all my life as I'd like to move into a higher level design/architects role at some point in time (I'm 35). Where do I/can I go from here?

• How To Run A Shell Script Again And Again Having X Interval Of Time?

  - by Muhammad Hassan

  I have a shell script in my Ubuntu Server 14.04 LTS at ./ShellScript.sh. I setup /etc/rc.local to run the shell script after boot but before login using below code. Run this: sudo nano /etc/rc.local then add following and save. #!/bin/sh -e # # rc.local # # This script is executed at the end of each multiuser runlevel. # Make sure that the script will "exit 0" on success or any other # value on error. # # In order to enable or disable this script just change the execution # bits. # # By default this script does nothing. #!/bin/bash ./ShellScript.sh exit 0 Now I want to run/execute this shell script again and again having 15min of time interval between every run after boot but before login. So Can I do it? Update 1:) When I run crontab -e then I got the following. Now What to do? no crontab for root - using an empty one Select an editor. To change later, run 'select-editor'. 1. /bin/ed 2. /bin/nano <---- easiest 3. /usr/bin/vim.basic 4. /usr/bin/vim.tiny Choose 1-4 [2]: After selecting 2, I got crontab: "/usr/bin/sensible-editor" exited with status 2 UPDATE 2:) Update ShellScript.sh like below... #!/bin/bash # Testing ShellScript... while true do echo "ShellScript Start Running..." ********************************** All My Shell Script Codes/Script/Commands ********************************** echo "ShellScript End Running..." exit 0 sleep 900 done Then Run this: sudo nano /etc/rc.local then add following and save. #!/bin/sh -e # # rc.local # # This script is executed at the end of each multiuser runlevel. # Make sure that the script will "exit 0" on success or any other # value on error. # # In order to enable or disable this script just change the execution # bits. # # By default this script does nothing. sh ./ShellScript.sh & exit 0

• Fast Data: Go Big. Go Fast.

  - by J Swaroop

  Cross-posting Dain Hansen's excellent recap of the Big Data/Fast Data announcement during OOW: For those of you who may have missed it, today’s second full day of Oracle OpenWorld 2012 started with a rumpus. Joe Tucci, from EMC outlined the human face of big data with real examples of how big data is transforming our world. And no not the usual tried-and-true weblog examples, but real stories about taxi cab drivers in Singapore using big data to better optimize their routes as well as folks just trying to get a better hair cut. Next we heard from Thomas Kurian who talked at length about the important platform characteristics of Oracle’s Cloud and more specifically Oracle’s expanded Cloud Services portfolio. Especially interesting to our integration customers are the messaging support for Oracle’s Cloud applications. What this means is that now Oracle’s Cloud applications have a lightweight integration fabric that on-premise applications can communicate to it via REST-APIs using Oracle SOA Suite. It’s an important element to our strategy at Oracle that supports this idea that whether your requirements are for private or public, Oracle has a solution in the Cloud for all of your applications and we give you more deployment choice than any vendor. If this wasn’t enough to get the juices flowing, later that morning we heard from Hasan Rizvi who outlined in his Fusion Middleware session the four most important enterprise imperatives: Social, Mobile, Cloud, and a brand new one: Fast Data. Today, Rizvi made an important step in the definition of this term to explain that he believes it’s a convergence of four essential technology elements: Event Processing for event filtering, business rules – with Oracle Event Processing Data Transformation and Loading - with Oracle Data Integrator Real-time replication and integration – with Oracle GoldenGate Analytics and data discovery – with Oracle Business Intelligence Each of these four elements can be considered (and architect-ed) together on a single integrated platform that can help customers integrate any type of data (structured, semi-structured) leveraging new styles of big data technologies (MapReduce, HDFS, Hive, NoSQL) to process more volume and variety of data at a faster velocity with greater results.  Fast data processing (and especially real-time) has always been our credo at Oracle with each one of these products in Fusion Middleware. For example, Oracle GoldenGate continues to be made even faster with the recent 11g R2 Release of Oracle GoldenGate which gives us some even greater optimization to Oracle Database with Integrated Capture, as well as some new heterogeneity capabilities. With Oracle Data Integrator with Big Data Connectors, we’re seeing much improved performance by running MapReduce transformations natively on Hadoop systems. And with Oracle Event Processing we’re seeing some remarkable performance with customers like NTT Docomo. Check out their upcoming session at Oracle OpenWorld on Wednesday to hear more how this customer is using Event processing and Big Data together. If you missed any of these sessions and keynotes, not to worry. There's on-demand versions available on the Oracle OpenWorld website. You can also checkout our upcoming webcast where we will outline some of these new breakthroughs in Data Integration technologies for Big Data, Cloud, and Real-time in more details.

• How to Format a USB Drive in Ubuntu Using GParted

  - by Trevor Bekolay

  If a USB hard drive or flash drive is not properly formatted, then it will not show up in the Ubuntu Places menu, making it hard to interact with. We’ll show you how to format a USB drive using the tool GParted. Note: Formatting a USB drive will destroy any data currently stored on it. If you think that your USB drive is already properly formatted, but Ubuntu just isn’t picking it up, try unplugging it and plugging it back in to a different USB slot, or restarting your machine with the device plugged in on start-up. Open a terminal by clicking on Applications in the top-left of the screen, then Accessories > Terminal. GParted should be installed by default, but we’ll make sure it’s installed by entering the following command in the terminal: sudo apt-get install gparted To open GParted, enter the following command in the terminal: sudo gparted Find your USB drive in the drop-down box at the top right of the GParted window. The drive should be unallocated – if it has a valid partition on it, then you may be looking at the wrong drive. Note: Make sure you’re on the correct drive, as making changes on the wrong hard drive with GParted can delete all data on a hard drive! Assuming you’re on the right drive, right-click on the unallocated grey block and click New. In the window that pops up, change the File System to fat32 for USB Flash Drives, NTFS for USB Hard Drives that will be used in Windows, or ext3/ext4 for USB Hard Drives that will be used exclusively in Linux. Add a label if you’d like, and then click Add. Click the green checkmark and then the Apply button to apply the changes. GParted will now format your drive. If you’re formatting a large USB Hard Drive, this can take some time. Once the process is done, you can close GParted, and the drive will now show up in the Places menu. Clicking on the drive will mount it and open it in a File Browser window. It will also add a shortcut to the drive on the Desktop by default. Your USB drive is now ready to store your files!

• Convert Chrome Bookmark Toolbar Folders to Icons

  - by Asian Angel

  So you have your regular bookmarks reduced to icons but what about the folders? With our little hack and a few minutes of your time you can turn those folders into icons too. Condensing the Folders Reducing bookmark folders to icons is a little more tricky than regular bookmarks but not hard to do. Right click on the folder and select “Rename…”. The folder’s name should already be highlighted/selected as shown here. Delete the text…notice that the “OK Button” has become unusable for the moment. Now what you will need to do is: Hold down the “Alt Key” Type in “0160” (without the quotes) using the numbers keypad on the right side of your keyboard Release the “Alt Key” after you have finished typing in the number above Once you have released the “Alt Key” you will notice two things…the “cursor” has moved further into the text area and you can now click on the “OK Button” again. There is our folder after editing. And it works just as well as before but without taking up so much room. Here is how our “iconized” folder looks next to our bookmarks. Perfect! What if you want to reduce multiple folders to icons? Perform the same exact steps shown above for each folder and pack your “Bookmarks Toolbar” full of folder goodness! As seen here the folders will have a little more space between them in comparison with singular bookmarks due to the “blank name” for each folder. For those who may be curious this is what your bookmarks will look like in the “Bookmark Manager Page”. Note: If you export your bookmarks all bookmarks contained in multiple blank name folders will be combined into a single folder. Conclusion With just a little bit of work you can pack a lot of goodness into your “Bookmarks Toolbar”. No more wasted space… Similar Articles Productive Geek Tips Condense the Bookmarks in the Firefox Bookmarks ToolbarAccess Your Bookmarks with a Toolbar Button in Google ChromeAdd the Bookmarks Menu to Your Bookmarks Toolbar with Bookmarks UI ConsolidatorAdd a Vertical Bookmarks Toolbar to FirefoxReduce Your Bookmarks Toolbar to a Toolbar Button TouchFreeze Alternative in AutoHotkey The Icy Undertow Desktop Windows Home Server – Backup to LAN The Clear & Clean Desktop Use This Bookmarklet to Easily Get Albums Use AutoHotkey to Assign a Hotkey to a Specific Window Latest Software Reviews Tinyhacker Random Tips DVDFab 6 Revo Uninstaller Pro Registry Mechanic 9 for Windows PC Tools Internet Security Suite 2010 OutlookStatView Scans and Displays General Usage Statistics How to Add Exceptions to the Windows Firewall Office 2010 reviewed in depth by Ed Bott FoxClocks adds World Times in your Statusbar (Firefox) Have Fun Editing Photo Editing with Citrify Outlook Connector Upgrade Error

• SQL SERVER – SSAS – Multidimensional Space Terms and Explanation

  - by pinaldave

  I was presenting on SQL Server session at one of the Tech Ed On Road event in India. I was asked very interesting question during ‘Stump the Speaker‘ session. I am sharing the same with all of you over here. Question: Can you tell me in simple words what is dimension, member and other terms of multidimensional space? There is no simple example for it. This is extreme fundamental question if you know Analysis Service. Those who have no exposure to the same and have not yet started on this subject, may find it a bit difficult. I really liked his question so I decided to answer him there as well blog about the same over here. Answer: Here are the most important terms of multidimensional space – dimension, member, value, attribute and size. Dimension – It describes the point of interests for analysis. Member – It is one of the point of interests in the dimension. Value – It uniquely describes the member. Attribute – It is collection of multiple members. Size – It is total numbers for any dimension. Let us understand this further detail taking example of any space. I am going to take example of distance as a space in our example. Dimension – Distance is a dimension for us. Member – Kilometer – We can measure distance in Kilometer. Value – 4 – We can measure distance in the kilometer unit and the value of the unit can be 4. Attribute – Kilometer, Miles, Meter – The complete set of members is called attribute. Size – 100 KM – The maximum size decided for the dimension is called size. The same example can be also defined by using time space. Here is the example using time space. Dimension – Time Member – Date Value – 25 Attribute – 1, 2, 3…31 Size – 31 I hope it is clear enough that what are various multidimensional space and its terms.

• On the art of self-promotion

  - by Tony Davis

  I attended Brent Ozar's Building the Fastest SQL Servers session at Tech Ed last week, and found myself engulfed in a 'perfect storm' of excellent technical and presentational skills coupled with an astute awareness of the value of promoting one's work. I spend a lot of time at such events talking to developers and DBAs about the value of blogging and writing articles, and my impression is that some could benefit from a touch less modesty and a little more self-promotion. I sense a reticence in many would-be writers. Is what I have to say important enough? Haven't far more qualified and established commentators, MVPs and so on, already said it? While it's a good idea to pick reasonably fresh and interesting topics, it's more important not to let such fears lead to writer's block. In the eyes of any future employer, your published writing is an extension of your resume. They will not care that a certain MVP knows how to solve problem x, but they will be very interested to see that you have tackled that same problem, and solved it in your own way, and described the process in your own voice. In your current job, your writing is one of the ways you can express to your peers, and to the organization as a whole, the value of what you contribute. Many Developers and DBAs seem to rely on the idea that their work will speak for itself, and that their skill shines out from it. Unfortunately, this isn't always true. Many Development DBAs, for example, will be painfully aware of the massive effort involved in tuning and adding resilience to rapidly developed applications.

• On the art of self-promotion

  - by Tony Davis

  I attended Brent Ozar’s Building the Fastest SQL Servers session at Tech Ed last week, and found myself engulfed in a ‘perfect storm’ of excellent technical and presentational skills coupled with an astute awareness of the value of promoting one’s work. I spend a lot of time at such events talking to developers and DBAs about the value of blogging and writing articles, and my impression is that some could benefit from a touch less modesty and a little more self-promotion. I sense a reticence in many would-be writers. Is what I have to say important enough? Haven’t far more qualified and established commentators, MVPs and so on, already said it? While it’s a good idea to pick reasonably fresh and interesting topics, it’s more important not to let such fears lead to writer’s block. In the eyes of any future employer, your published writing is an extension of your resume. They will not care that a certain MVP knows how to solve problem x, but they will be very interested to see that you have tackled that same problem, and solved it in your own way, and described the process in your own voice. In your current job, your writing is one of the ways you can express to your peers, and to the organization as a whole, the value of what you contribute. Many Developers and DBAs seem to rely on the idea that their work will speak for itself, and that their skill shines out from it. Unfortunately, this isn’t always true. Many Development DBAs, for example, will be painfully aware of the massive effort involved in tuning and adding resilience to rapidly developed applications.

• Will Online Learning Save Higher Education (and does it need saving)?

  - by user739873

  A lot (an awful lot) of education industry rag real estate has been devoted to the topics of online learning, MOOC’s, Udacity, edX, etc., etc. and to the uninitiated you’d think that the education equivalent of the cure for cancer had been discovered. There are certainly skeptics (whose voice is usually swiftly trampled upon by the masses) who feel we could over steer and damage or destroy something vital to teaching and learning (i.e. the classroom experience and direct interaction with human beings known as instructors), but for the most part prevailing opinion seems to be that online learning will take over the world and that higher education will never be the same. Now I’m sure that since you all know I work for a technology company you think I’m going to come down hard on the side of online learning proselytizers. Yes, I do believe that this revolution can and will provide access to massive numbers of individuals that either couldn’t afford (from a fiscal or time perspective) a traditional education, and that in some cases the online modality will actually be an improvement over certain traditional forms (such as courses taught by an adjunct or teaching assistant that has no business being a teacher). But I think several things need immediate attention or we’re likely to get so caught up in the delivery that we miss some of the real issues (and opportunities) around online learning. First and foremost, we’ve got to give some thought to how traditional information systems are going to accommodate thousands (possibly hundreds of thousands) of individual students each taking courses from many, many different “deliverers” with an expectation that successful completion of these courses will result in credit at many or most institutions. There’s also a huge opportunity to refine the delivery platform (no, LMS is not a commodity when you are talking about online delivery being your sole mode of operation) as well as the course itself by mining all kinds of data from the interactions that the students have with the material each time they take it. Social data analytics tools will be key in achieving this goal. What about accreditation (badging or competencies vs. traditional degrees)? And again, will the information systems in place today adapt to changes in this area fast enough? The type of scale that this shift in learning could drive has the potential to abruptly overwhelm just about every system in place today in higher education. I would like to (with a not so gentle reminder) refer you back to a blog entry I wrote when I first stepped into my current role at Oracle in which I talked about how higher ed needs an “Oracle” more than at any other time in it’s evolution (despite the somewhat mercantilist reputation it has in some circles). There just aren’t that many organizations that can deliver the kinds of solutions “at scale” that this brave new world of online education will demand. The future may be closer than we think. Cole

• Are there new flexible texteditors? [closed]

  - by RParadox

  Vi(m) and Emacs are almost 40 years old. Why are they still the standard, and what attempts have been made at coming up with a new flexible editor? Are there any features which can not be built into vim/emacs? My question is similar to this one: Time to drop Emacs and vi? No one had a suggestion, which surprises me. I would have thought that the core of a texteditor is very small and that people brew their own. Perhaps nobody wants to deal with supporting all the modes? Edit to clarify my question: Instead of writing modes and scripts I ask myself, why there is not a much lightweight project, which lets people custom the editor more directly? Vim has 365395 LOC (C lines all included), Emacs 1.5 million LOC. Why is there a project with say 50k LOC, which is the core, why people can use more freely? Perhaps there is such project, I haven't looked very far. I thought about putting together modules from Vim myself and experimenting with some ideas. The core of editing shouldn't be more than 10k? Vim has a lot optimizations which is really an overkill nowadays. Basically I'm looking for a code base for my own editor and Vi/Emacs are I believe not intended to be used in this way. Bill Joy said the following about vi. http://web.cecs.pdx.edu/~kirkenda/joy84.html The fundamental problem with vi is that it doesn't have a mouse and therefore you've got all these commands. In some sense, its backwards from the kind of thing you'd get from a mouse-oriented thing. I think multiple levels of undo would be wonderful, too. But fundamentally, vi is still ed inside. You can't really fool it. Its like one of those pinatas - things that have candy inside but has layer after layer of paper mache on top. It doesn't really have a unified concept. I think if I were going to go back - I wouldn't go back, but start over again.

• How to run WordPress and Java web app running on Tomcat on the same server?

  - by Chantz

  I have to run a WordPress site served via Apache2 & Java-based webapp using Tomcat on the same server. When users come to example.com or example.com/public-pages they need to served from WordPress but when they come to example.com/private-pages they need to be served from the Tomcat. I have asked this question on serverfault where they suggested using different port, different IP & sub-domain. I want to go for different port solution since it will mean I need to buy only one SSL certificate. I tried doing the reverse proxy method by having the following in my default-ssl.conf <VirtualHost _default_:443> ServerAdmin webmaster@localhost ServerName localhost:443 DocumentRoot /var/www <Directory /var/www> #For Wordpress Options FollowSymLinks AllowOverride All </Directory> <Proxy *> Order deny,allow Allow from all </Proxy> ProxyRequests Off ProxyPass /private-pages ajp://localhost:8009/ ProxyPassReverse /private-pages ajp://localhost:8009/ SSLEngine on SSLProxyEngine On SSLCertificateFile /etc/apache2/ssl/apache.crt SSLCertificateKeyFile /etc/apache2/ssl/apache.key </VirtualHost> As you have noticed I am using mod_proxy_ajp in Apache2 for this. And that my Tomcat is listening to port 8009 and then serving content. So now when I go to example.com/private-pages I am seeing the content from my Tomcat. But 2 issues are happening. All my static resources are getting 404-ed, so none of my images, CSS, js are getting loaded. I see that the browser is requesting for the resources using URL example.com/css/* This will clearly not work because it translates to example.com:80/css/* instead of example.com:8009/css/* & there are no such resources in the WordPress directory. If I go to example.com/private-pages/abcd I am somehow kicked to the WordPress site (which obviously displays a 404 page). I can understand why #1 is happening but have no clue why the #2 is happening. Regardless, if there is another clean solution for resolving this, I would appreciate y'alls help.

• BSOD Dump - EXCEPTION_DOUBLE_FAULT - ON Windows 2008 Server 64bit

  - by Mark K

  Hello, my windows 2008 server (datacenter ed) 64bit , have recently created a series of BSOD on a different applications. the error message is in general EXCEPTION_DOUBLE_FAULT. Can anyone please help with the analysis of the dump file bellow- Best regards, Mark 2: kd !analyze -v * Bugcheck Analysis * * UNEXPECTED_KERNEL_MODE_TRAP (7f) This means a trap occurred in kernel mode, and it's a trap of a kind that the kernel isn't allowed to have/catch (bound trap) or that is always instant death (double fault). The first number in the bugcheck params is the number of the trap (8 = double fault, etc) Consult an Intel x86 family manual to learn more about what these traps are. Here is a portion of those codes: If kv shows a taskGate use .tss on the part before the colon, then kv. Else if kv shows a trapframe use .trap on that value Else .trap on the appropriate frame will show where the trap was taken (on x86, this will be the ebp that goes with the procedure KiTrap) Endif kb will then show the corrected stack.

• Mouse wheel in VirtualPC (mostly) does not work on 64-bit Windows 7 RC

  - by JonStonecash

  I have recently upgraded my laptop from WinXP Pro (32-bit) to Windows 7 RC (64-bit). I have a number of VirtualPC 2007 images that I use for testing on various platforms and looking at beta software. I have installed the 64-bit version of VirtualPC. The images all work with the exception of the mouse wheel within the virtual machine. I have tried this out with WinXP Pro, Windows 7 RC, and Windows Server 2008 images. All are 32-bit and all exhibit the same behavior: a gentle rotation of the wheel does nothing; a quick rotation of the wheel sometimes gets a scroll and sometimes not. I regard this behavior as unusable as I tend to use the mouse wheel a lot. All of this worked just fine on WinXP. I have re-installed the Virtual machine additions on all of the machines. The Windows 7 RC virtual image was created after the upgrade to Windows 7 and the 64-bit version of VirtualPC (just to isolate the possibility that I had corrupted the images during the transition). I have googled, binged, and yahoo-ed. There are scattered mentions of this problem (dating back to VPC 2004) but no solutions. I am aware that I could start up one of these images and then use remote desktop connections to get access to that image. I, in fact, do just that for some development that I am doing; the mouse works just fine. This is acceptable in this case because I spend hours at a time in the development VM. These test environments are different in that I will bring up an image for just a short time: minutes rather than hours. Adding the rdc step is much more significant in these cases. Does anyone have any idea of what to do next?

• Netcat (nc) traditional package for RHEL 6.x?

  - by HTTP500

  I'm trying to use the Percona Apache Monitoring [Cacti] Template for Memcached. They do indeed warn that you can't use the openbsd version of the package and provide a solution for Ubuntu/Debian users, i.e.: You need nc on the server. Some versions of nc accept different command-line options. You can change the options used by configuring the PHP script. If you don’t want to do this for some reason, then you can install a version of nc that conforms to the expectations coded in the script’s default configuration instead. On Debian/Ubuntu, netcat-openbsd does not work, so you need the netcat-traditional package, and you need to switch to /bin/nc.traditional... Since the RHEL 6.x version indeed comes from openbsd (confirmed by rpm -qi nc) how does one go about getting this installed on RHEL/CentOS? Anyone else running these Percona templates on RHEL/CentOS? What did you do? alien the Debian package? Update 1: FWIW, I tried to use GNU netcat by compiling it from source but it doesn't seem to have the exact options required by the Cacti template either (i.e. there is no analogy for -C or -q1 so it seems) Update 2: I alien[ed] the netcat-traditional_1.10-38_amd64.deb package to make a .tgz and it does produce a binary "nc.traditional" and that version has the -q option but no -C Cheers

• Can an image based backup potentially corrupt data?

  - by ServerAdminGuy45

  I'm considering doing image based backups (Acronis) on production Windows systems during non-peak hours. I'm just wondering if they can potentially lead to application data corruption. Lets say that I have a database that is getting hit pretty hard. Could I potentially have the beginning blocks of the database be commit ed to the image, data inserted into the db (which changes the beginning blocks of the DB on the server but not the image), then the blocks of data committed to the image (leading to an inconsistent state). Here's an example of what I'm trying to illustrate. Imagine a simple data structure which has a number in the front which represents the number of "a"s in a file. The number and data are delimited by a "-". For example: 4-ajjjjjjjajuuuuuuuaoffffa If an "a" is changed, the datastructure resets the number in the begining of the file such as: 3-ajjjjjjjajuuuuuuuboffffa I assume acronis writes block by block being a straight up image so here is what i'm invisioning happening with my database t0: 4-ajjjjjjjajuuuuuuuaoffffa ^pointer is here t1: 4-ajjjjjjjajuuuuuuuaoffffa ^pointer is here (all data before this is comitted to the image) t2: 4-ajjjjjjjajuuuuuuuboffffa ^pointer is here (all data before this is comitted to the image) Also notice how one of the "a"s change to a b. There are only 3 "a"s now t3: 4-ajjjjjjjajuuuuuuuboffffa ^pointer is here (all data before this is comitted to the image) The final image now reads "4-ajjjjjjjajuuuuuuuboffffa", while the true data is "3-ajjjjjjjajuuuuuuuboffffa" leading to a corrupt "database". Basically changes further down the blockchain could be reflected in the image, while important header and synchronization could already be committed. The out of date header information doesn't accurately reflect the structure of the blocks to come.

• Returning a 404 page when a folder is accessed from one domain, but allowing access from other domains and IP addresses

  - by okw

  Situation: I want to return a 404 page ("404.php") when a folder ("hidden") is accessed from the example.com domain. I want the same folder to be accessible from a subdomain ("hidden.example.com") or from a different domain ("hidden.com") which are both configured in a single VirtualHost entry. The server has multiple IP addresses that it listens on. Each IP address serves identical content from the example.com domain (sharing a VirtualHost entry.) I want the folder to be accessible from the IP address. The server is configured to use SSL/TLS/HTTPS. HTTPS is optional on example.com, but HTTPS is enforced in the .htaccess file for the hidden folder using a rewrite rule shown below. /www/hidden/.htaccess RewriteCond %{HTTPS} !=on RewriteRule .* https://%{SERVER_NAME}%{REQUEST_URI} [R,L] I know that {SERVER_ADDR} gives the server's IP address, but does it return the one that the client is requesting from? I'm also starting to think that something in the VirtualHosts file would be more appropriate. Any thoughts on this? What should be allowed: http://87.65.43.21/hidden/ https://87.65.43.21/hidden/ http://12.34.56.78/hidden/ https://12.34.56.78/hidden/ http://hidden.example.com/ https://hidden.example.com/ http://hidden.com/ https://hidden.com/ http://www.hidden.com/ https://www.hidden.com/ What should be 404-ed with 404.php http://example.com/hidden/ https://example.com/hidden/ http://www.example.com/hidden/ https://www.example.com/hidden/ http://example.com/hidden/hiddenfile.php https://example.com/hidden/hiddenfile.php etc. Thanks.

• Mustek 1200 CP driver SFC4.SYS bluescreens with BAD_POOL_HEADER

  - by Slink84

  I have Windows XP SP2. Recently it started bluescreening right after starting up with 'BAD_POOL_HEADER', 0x00000019 error caused by SFC4.SYS driver. After googling for a while I've found out that this is my Mustek's 1200 CP scanner driver. Booting in safe mode and uninstalling it solved the problem... And created another one: now I can't use my scanner. The weird thing is, that it has been working for a while on this PC without any problems. It all started suddenly, and I can't remember installing anything that might have affected it. Reverting to several earlier system restore points didn't help. I've tried re-installing it from the Mustek website, just in case if my copy got corrupted or infected by a virus, but it did not help - it still bluescreens. Also, I've installed Avast and scanned my PC - there were no viruses found. If anyone had such a problem before or has an idea what might have caused it, please help. ED: @Michael Todd: ...try installing on another PC... I've installed it on my friends PC. He has the same OS version, with the latest updates just like mine (he wasn't too happy, even after I've assured him that it is easy to fix by uninstalling that driver :] ). It worked fine - no bluescreens or whatsoever. So I think I've narrowed it down to either BIOS settings, or some wicked driver conflict. Next thing I'm going to try is to re-install XP, or install windows 7. I'm not too happy with a prospect of mucking about with BIOS settings...

• Deciphering an IIS6 Httperr log file

  We have a Windows 2003 R2 SP2 server with iis6 that is creating a 1024kb httperr file every minute. I can't figure out what I'm looking at. Here's a snippet: 2010-03-24 13:15:05 10.53.2.35 1667 10.53.2.12 80 HTTP/1.1 PUT /hserver.dll?&V01|&IMAC=0080646077AB|CID=32|CN=LWT0080646077AB|ED=1|IP=10.53.2.35|SM=255.255.255.0|GW=10.53.2.1|SN=10.53.2.255|DM=logs.com|1D=10.53.2.12|2D=10.101.2.12|0D=1|AL=/usr/sbin/netxserv|AV=4.1.0.0|CP=VIAüEstherüprocessorüü800MHz|CPS=800|RM=190512|B1=1.18|PD2=1024x768x16ü@ü60Hz|IM=6.6.2-02|CI=3600|SN#=6KHDG301300|OS=23|VI=1|P1=24|TZO=-301|TZ=CDT|FS=128|MD=2003-04|CO=|LO=|AP0=BaseüSystem|NA|6.6.2-02|AP1=RapportüAgent|NA|4.1.0-3.26|AP2=TrueType|NA|6.8.0-3.4|AP3=WebFonts|NA|2.0.4-3.6|AP4=TrueTypeüFonts|NA|6.8.0-3.5|AP5=Network_login|NA|1.0.0-1.0.3|AP6=ScreenüSaver|NA|3.13|AP7=DMonitor|NA|1.0.0-0.4.0|AP8=MozillaüFirefox_15|NA|1.5.0.8-3.6|AP9=RemoteüShadow|NA|3.17|AP10=RemoteüDesktop|NA|1.6.0-1.0|AP11=SNMP|NA|5.1.3.1-3.13|AP12=LinuxüPrinting|NA|3.8.27-3.33|AP13=SSH|NA|3.8.1-3.25|AP14=ThinPrint|NA|6.2.87-0.2|AP15=XDMCP|NA|6.8.0-3.29|AP16=Ericom|NA|8.2.0-3.29|AP17=Daylightüsavingütimeüupdate|NA|1.1.0-1.0.0| 411 - LengthRequired - What on earth am I looking at? Nothing in the system or app logs. Finally, in iis manager, Default Web Site label has boxes instead of spaces. Very odd.

• Home network with two isolated separate subnets, running on cablemodem/router and WRT-router.

  - by Johan Allgoth

  I have a new connection with a nice new router/cable-modem. I'd like to setup it up optimally and needs some pointers. I am a complete n00b when it comes to routing. I want to end up with two separate subnets, 10.1.2.0/24 and 192.168.1.0/24 each available on their own wireless channel/SSID. Both firewalled. I want my wired computers on the gigabit switch, optimally with public ips. I want to be able to reach 192.168.1.0/24 from 10.1.2.0/24, but not vice versa. Everyone should have internet access. Hardware and capabilities: Netgear CG3100. Handles cable connection. Gigabit switch. 802.11n. Can do DHCP, firewall, NAT etc. Can choose subnet. Can turn of NAT and if so hand out up to 4 public ips. Somewhat challenged when it comes to configuration. WRT-router. Runs DD/Open-WRT very stable. 100 Mbit switch. 802.11.g Can do DHCP, firewall, NAT etc. Can choose subnet. Highly configurable. I hope to be able to keep 10.1.2.0/24 on the CG3100, for speed reasons and 192.168.0.0/24 on the WRT-router for quota and user control reasons. On my 10.1.2.0/24 network I plan on running servers for various services. Should I turn of NAT on the WRT-router? Or on the cable modem? Activate what in that case? Is double NAT always f-ed up?
