• .htaccess redirect working on localhost but not on server

  - by Thread7

  I want users who hit my web site's root directory to be sent to a subdirectory. So anyone going to: http://MyDomain.com or /index.php would be sent to http://MyDomain.com/subdir I used the .htaccess file to successfully do this on my local machine (with Apache 2). But it doesn't work on the server? Users still see the default index.php in the root directory. Here is my simple .htaccess file. Any ideas? RewriteEngine On Redirect /index.php http://MyDomain.com/subdir/ Now my httpd.conf file AccessFileName .htaccess <Directory /> Options FollowSymLinks AllowOverride All </Directory> <Directory "/var/www/icons"> Options Indexes MultiViews FollowSymLinks AllowOverride None Order allow,deny Allow from all </Directory> <Directory "/var/www/cgi-bin"> AllowOverride None Options None Order allow,deny Allow from all </Directory> <IfModule mod_negotiation.c> <IfModule mod_include.c> <Directory "/var/www/error"> AllowOverride None Options IncludesNoExec AddOutputFilter Includes html AddHandler type-map var Order allow,deny Allow from all LanguagePriority en es de fr ForceLanguagePriority Prefer Fallback </Directory> </IfModule> </IfModule>

• Access denied when trying to open files/folders after reinstall [closed]

  - by user711532

  Possible Duplicate: Access Denied when saving a file in Windows 7 I installed Windows 7 fresh on a new machine. Now when I unarchive (winrar or 7z etc. ) to Program files (x86) (for example), access denied. Even if I copy a file to a folder I installed an app to it is still access denied. I checked the security, it looks like full control is given to the creator - this is weird as I never ran across this before (same version of Windows 7 - its just a fresh install after some new hardware). It is the same effect as if I was editing the hosts file, and you do not use "run as admin" you will not be able to save it, yo will have to save it somewhere else. This "file copy" issue I ran into is the same. I could change all these permissions, however this is something I never had to do before. I am the admin, why did the install, not give me "full control"? How can this be globally fixed. I cannot change the permissions - they are greyed out - so that is weird as well. If I was a standard reason, It would make sense, however, again, I am the admin.

• Friendly Intranet Addresses

  - by Jmyster

  Relativly new to IIS. I'm attempting to set up multiple sites in my Intranet on one server. The server already has SharePoint Installed on it and has a binding *:80. So when I type //ServerName I get the home page of SharePoint. I get how that works. I set up a new site in IIS and set the Binding to *:30015. On a remote machine if I type //ServerName:30015 in a web browser, I get the new site. Awesome, working as intended. My Questions: Can/How do i set it up so that I can type //DivisionAppName or //Division.AppName and have it resolve itself to //ServerName:30015? Is this something I have to register with my Company's DNS server? I hope not, getting my corprate IT to assist is a nightmare. What I tried: I have added Bindings with the Host Name filled in with both DivisionAppName or Division.AppName and port 30015 but that doesn't seem to work.

• In Windows 7 is there a way to login from any user account and see the same workspace and be able to use the running programs of another user?

  - by WickedMongoose

  Our group has a number of Test Stands with PCs that are currently being accessed with a single group login. It has been sent from on high that this is not the way to do things for security reasons and we all agree. However. Multiple team members from around the world log into these Test Stands and need to be able to access programs that have been run from what would be different user profiles if we were to no longer have a single common login. Is there a way to have a common workspace such that when different users login, they will be able to see and interact with all running applications as if they were using a common login? Applications that we run link to and monopolize hardware resources connected to the PC and it is time consuming to restart and reload settings every time a new user logs in. Even if the program did not monopolize the hardware many of these programs are resource intensive and require a large portion of each machine's RAM to run, so trying to run the application again when it is already running from multiple user accounts would quickly consume all system resources. Simple Example: I open a chrome browser while logged into our pc. I then logout and another team member remotes in and should be able to see my open browser and be able to interact with it as if he were the one who opened it. Any alternative process flows or solutions from someone who has gone through a similar transition would be appreciated. This is not a request for how to give all users access to the ability to run a program, but it is the request for how to allow all users access to interact with running applications that have been started by other users and need to be interacted with as if the new user started and has control of the application.

• Mac OS X: Applications not responding

  - by Robot55

  This happens to me several times a day. I'll quit an app, the window will close, but the app won't finish shutting down. It stays open in the dock, and right clicking and force quit show not responding. Force quit won't work. I can't shut the app down. Starting any other app when this happens causes that app to behave in exactly the same way: the icon opens in the dock, but the app is non-responsive and can't be forced to quit. Can't access terminal when this happens, because it locks up just like all the apps. While I haven't tried to open every app, I think any app I try to open when this is happening will lock up. If I relaunch Finder, it too locks up and then the only thing left is to hold down the power button for a hard reboot. Any app that is running while this is happening will continue to run normally unless I try to shut it down. Repairing disk permissions has no effect. I also did a time machine and a full restore on a brand new MbP - and sure enough, after restore, the new MbP suffers form the same problem. Creating a new user has no effect. Any thoughts?

• Allocating More Than 4 GB Of Memory

  - by TPatti

  I am facing an issue with memory allocation. I have: Host OS: Microsoft Windows XP - Professional x64 Edition - Version 2003 - Service Pack 2. Host Physical Memory: 8 GB Guest OS: Red Hat Enterprise Linux WS release 4 (Nahant Update 5). I am not sure if it is 32 or 64 bits. The lsb_release -a command says that argument LSB Version: core-3.0-ia32, so I guess that would be 32 bits... VMware Player Version: 2.5.2 build-156735 I would like that VMware Player could allocate more that 4 GB, but when I go to the setting, it only lists 4 GB. If I choose the "About" option, it actually says that I have 8 GB installed in the host machine. This VMware image created by someone else and provided to me, apparently done with VMware Workstation 5. Why can't I allocate 8 GB? Where is the problem? In the WMware Player Version, Guest OS or Host OS? How can I solve this? I understand that for this version of player there isn't one version for 32 and another for 64 bits.

• VM automatic provisioning advice

  - by jdgregson

  In my lab we have 24 workstations, each with five technician-maintained virtual machines set up in VMware Workstation. These provide a lot of management overhead, as we have to update them as well as the host operating systems every three months (the start of the next quarter), which adds up to 144 systems to update instead of just 24. Whenever we need to reimage the hosts, the VMs add another 130GB to each image, which is over 3TB of extra data to send over the network, and a lot more time to apply each image, and then we still have to boot all 120 VMs and assign them a unique IP Address and host names. We would like to get the VMs off the hosts and onto a server, but after looking around for a few days, I still don't know where to begin looking for a solution. There may be a better way to do this, but in my mind, the ideal solution would be to replace the VMs on the host machines with five Thin Client operating systems, each configured to connect to a server and be sent or connected to a unique virtual machine. We can't have 120 VMs running on the server all the time, so the server would have to create a copy of the VM from a template whenever a student tries to boot one, and destroy the VM after the student is finished with it. If there is another client application that has to be installed on the hosts that would be fine, the only reason I'd like to keep them in VMware Workstation is because students already know to look there for the VMs when they need to use them. What, if any, virtualization software will allow this? Is there some other solution I'm not seeing?

• Outlook 2010: Can I search Only My: Inbox, All Inbox Subfolders, and Specified Archive File Folders all at once

  - by JLH

  The setup is a user that has a laptop with Outlook 2010. We have Outlook hosted by Sherweb. The user that has a large number of emails (40,000) in a single Inbox subfolder. (I believe) Having such a large number of emails in an inox is slowing the users laptop down and I want to start moving old emails to a seperate pst file on a machine on our network. The problem I have is the user needs to be able to search all 40,000 emails. Right now he can can search do a search on the single subfolder. I would like to be able to move some of the emails to a seperate pst so I can compact the Inbox and still give them a 'one-click' search function that is still fairly quick. I don't think the 'Search All Outlook Items' is the soltuion because this will search all outlook folders -- sent items, other public folders. P.S. I'm not a expericenced outlook administrator, so there may be some assumptions in my questions that are wrong. I have no problem with somebody showing the error of my ways.

• Softfail / Failure Notice on SMTP

  - by pascal1954

  Hey, i'm searching for an answer for about 24 hours now and I still can't find any really useful help... The problem appears as the following: I'm running a debian server with Plesk 9.5.3 and qmail. Since a few weeks I'm not able to send mails to some particular servers (like web.de, aol.com). Hence I get failure notices like "Sorry, I wasn't able to establish an SMTP connection." But when I try to send mails to gmail.com - it works! Gmail only reports a softfail in the mail header like so: Received: from h1600XXX.?none? (DOMAIN2.TLD [XX.XXX.XX.XX]) Received-SPF: softfail (google.com: best guess record for domain of transitioning [email protected] does not designate 85.XXX.XX.XX as permitted sender) client-ip=85.XXX.XX.XX This sounds like a dns problem for me, but I can't get an answer for that... What makes me wondering is: h1600XXX is correct, but it should look like h1600XXX.stratoserver.net, not ?none? DOMAIN2.TLD (first line) is different from DOMAIN1 (second line). Both are hosted on this machine, but is this correct? DOMAIN1 is the one I send this mail from. Hopefully someone could help me! If you need more specific information, let me know. Thanks in advance!!! Best regards

• Copy past speed very slow for a large number of files on Windows [closed]

  - by Arno2501

  I've run the following test I've created a folder containing 15'000 files of 400 bytes using this batch : @ECHO off SET times=15000 FOR /L %%i IN (1,1,%times%) DO ( fsutil file createnew filename%%i.txt 400 ) then I copy past it on my Windows Computer using this command : robocopy LargeNumberOfFiles\ LargeNumberOfFiles2\ After it has completed I can see that the transfer rate was 915810 Bytes/sec this is less than 1 MB/s. It took me several seconds to copy 7 MBytes Please note that this is very slow. I've tried the same with a folder with a single file of 50 Mbytes and the transfer rate is 1219512195 Bytes/sec. (yeah GB/s) instantaneous. Why copying large number of files take so much time - ressources on a windows filesystem ? Please note that I've tried to do the same on a linux system which runs on the same computer in a virtual machine (vmware player) with ext3 filesystem. I use the cp command and the copy is instantaneous ! Please also note the following : no antivirus I've tested that behaviour on multiple windows computers (always ntfs) i always get comparable results (transfer rate under 1MB/s avg 7-8 seconds to copy 7 MBytes) I've tested on multiple linux ext3 system the copy is always instantaneous for that amount (15000 files of 400 bytes) The question is about understanding what makes windows filesystem so slow to copy large number of files compared to a linux one for instance.

• Redirect traffic from 127.0.0.1 to 127.0.0.1 on port 53 to port 5300 with iptables

  - by Zagorax

  I'm running a local dns server on port 5300 to develop a software. I need my machine to use that dns but I wasn't able to tell /etc/resolv.conf to check on a different port. I searched a bit on google and I didn't find a solution. I set 127.0.0.1 as nameserver on /etc/resolv.conf. This is my whole /etc/resolv.conf: nameserver 127.0.0.1 Could you please tell me how can I redirect outbound traffic on port 53 to another port? I tried the following but it didn't work: iptables -t nat -A PREROUTING -p tcp --dport 53 -j DNAT --to 127.0.0.1:5300 iptables -t nat -A PREROUTING -p udp --dport 53 -j DNAT --to 127.0.0.1:5300 Here is the output of iptables -t nat -L -v -n (with suggested rules): Chain PREROUTING (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination 0 0 REDIRECT tcp -- * * 0.0.0.0/0 0.0.0.0/0 tcp dpt:53 redir ports 5300 0 0 REDIRECT udp -- * * 0.0.0.0/0 0.0.0.0/0 udp dpt:53 redir ports 5300 Chain POSTROUTING (policy ACCEPT 302 packets, 19213 bytes) pkts bytes target prot opt in out source destination Chain OUTPUT (policy ACCEPT 302 packets, 19213 bytes) pkts bytes target prot opt in out source destination

• Randomly unusable wireless connection. Oddest issue ever...

  - by Hallucynogenyc

  I have two desktop computers a laptop and a smartphone. All of them connect perfectly to my router (WRT54GL with Tomato firmware), but randomly (once a week maybe) something odd happens: For over an hour or so one of the desktop computers (Windows 7 Pro x64) will just refuse to connect properly to the router. Only that computer and only to that network. I can connect all the other machines to the router perfectly and I can connect properly to other networks with that machine. What I mean by "not being able to connect properly" I mean that the OS will just tell me "not able to connect to.." or that it will connect but then say that it has no Internet access or it connects but will then take minutes to load any website, even the router web interface. I've tried to change from WPA2 to WEP and back to WPA2, I've tried different network adapters (one internal PCI card and one USB external card), removing networks from Windows and adding again... without making any difference. It works for some days but at the end, it ends happening at some time. I just have no clue on what the hell could be going on here. I first thought it was the network adapter, then the router, then Windows... Thanks in advance

• How to remove all data that a website stores on a PC? [on hold]

  - by s.r.a

  I was a member in a computer forum website (sevenforums.com) for months. Two days ago I created a thread and many members participated in it, some of them asked me some irrelevant questions and I said “this question is irrelevant” and didn’t get them the answer. Thread finished and I could get the answer from another website and posted it to that website to arise members’ knowledge. Yesterday like every day I went to that website and faced a massage which was banning me, and my account was disabled. I shocked and I didn’t have even any option to appeal against that wrong decision. So I had to do something. And I did the following works: 1- I disconnected my Internet connection and cleared all the history data on the browser I use, the Google chrome. 2- I then ran “ccleaner” tool and marked almost all the options and then clicked on “run” button. Then it cleared all the data including the cookies. 3- I connected the machine (desktop) to the Internet and immediately changed my IP address. 4- I created a new Hotmail account and tried to register as a new member to that website (sevenforums.com). 5- I succeeded and my new account was enabled so I start to posting to that website. But unfortunately, after less than 1 minute I faced this message: “You are already banned”! My question is that, how they could know me again? How to create a new account without they know me? Thanks in advance.

• Why are my SharePoint downloads not completing for outside users?

  - by CT

  I am using WSS 3.0 with Microsoft Server 2003. I am running into the following problem. On a pretty frequent basis, outside users are having trouble downloading documents. Some downloads are completing while the download is still incomplete. So for instance, a PDF is a 17MB file. If I download it from within the office, all 17MBs are downloaded and it opens. If I download it from an outside connection, it may download anywhere from 5-10 MB of the file and then say it is complete. When these partial downloads are opened, it gives the user the error, this file is corrupt and cannot be repaired. I have solved this problem on some of the occasions by simply deleting the document and uploading a new copy of the document. This does not always work. Are there known bugs? Are the Internet settings that need to be modified on the outside user's machine? Does anyone else run into this?

• Windows 7 constantly accessing hard drive [duplicate]

  - by Zohar

  Possible Duplicate: Tool which finds which process is causing the heavy hard drive activity? Did you notice that on Windows 7 (I use 64-bit) the hard drive LED is constantly blinking, which means that the OS is constantly wearing the hard drive by accessing it? It's something related to the system process, and it even occurs in safe mode, so I don't think it's a third party software problem. Has anyone experienced this problem as well, and is it a Windows problem, or caused by something else? Edit: My indexing service is reduced to indexing only the Start Menu. Even if it was set for the whole computer, it would eventually stop; that's not it. My friends also suffer from the same problem. Please answer my first question: have any of you have seen a Windows 7 machine whose hard drive LED is at rest? I'm also trying to track down the offending process using procmon and Resource Monitor, and it actually seems like a system process. It could also be svchost.exe, and I'm not sure which file they are accessing since I see a lot of activity which I can't make sense of. It's loading system DLLs, accessing registry keys, and other nonsense.

• Update Manager unable to get updates

  - by dPEN

  In last few days my Ubuntu 11.10 update manager is unable to get new updates. When I checked update log I saw that for couple of updates it says "Network isn't available". For other updates it downloaded logs and and internet connection also works fine. Unable to attached screenshot due to SPAM prevention policy. But for below Release gpgv:/var/lib/apt/lists/partial/extras.ubuntu.com_ubuntu_dists_oneiric_Release.gpg it says "Network isn't available" For all other Releases it is downloading fine. And due to this I dont see any update available in last 10 days.

For example, to use with the two sample programs QueueSend.java and QueueReceive.java which will be shown in later examples. Additional, detailed information on JMS can be found in the following Oracle documentation: Oracle® Fusion Middleware Configuring and Managing JMS for Oracle WebLogic Server 11g Release 1 (10.3.6) Part Number E13738-06 http://docs.oracle.com/cd/E23943_01/web.1111/e13738/toc.htm 1. Introduction and Definitions A JMS queue in Weblogic Server is associated with a number of additional resources: JMS Server A JMS server acts as a management container for resources within JMS modules. Some of its responsibilities include the maintenance of persistence and state of messages and subscribers. A JMS server is required in order to create a JMS module. JMS Module A JMS module is a definition which contains JMS resources such as queues and topics. A JMS module is required in order to create a JMS queue. Subdeployment JMS modules are targeted to one or more WLS instances or a cluster. Resources within a JMS module, such as queues and topics are also targeted to a JMS server or WLS server instances. A subdeployment is a grouping of targets. It is also known as advanced targeting. Connection Factory A connection factory is a resource that enables JMS clients to create connections to JMS destinations. JMS Queue A JMS queue (as opposed to a JMS topic) is a point-to-point destination type. A message is written to a specific queue or received from a specific queue. The objects used in this example are: Object Name Type JNDI Name TestJMSServer JMS Server TestJMSModule JMS Module TestSubDeployment Subdeployment TestConnectionFactory Connection Factory jms/TestConnectionFactory TestJMSQueue JMS Queue jms/TestJMSQueue 2. Configuration Steps The following steps are done in the WebLogic Server Console, beginning with the left-hand navigation menu. 2.1 Create a JMS Server Services > Messaging > JMS Servers Select New Name: TestJMSServer Persistent Store: (none) Target: soa_server1  (or choose an available server) Finish The JMS server should now be visible in the list with Health OK. 2.2 Create a JMS Module Services > Messaging > JMS Modules Select New Name: TestJMSModule Leave the other options empty Targets: soa_server1  (or choose the same one as the JMS server)Press Next Leave “Would you like to add resources to this JMS system module” unchecked and  press Finish . 2.3 Create a SubDeployment A subdeployment is not necessary for the JMS queue to work, but it allows you to easily target subcomponents of the JMS module to a single target or group of targets. We will use the subdeployment in this example to target the following connection factory and JMS queue to the JMS server we created earlier. Services > Messaging > JMS Modules Select TestJMSModule Select the Subdeployments  tab and New Subdeployment Name: TestSubdeployment Press Next Here you can select the target(s) for the subdeployment. You can choose either Servers (i.e. WebLogic managed servers, such as the soa_server1) or JMS Servers such as the JMS Server created earlier. As the purpose of our subdeployment in this example is to target a specific JMS server, we will choose the JMS Server option. Select the TestJMSServer created earlier Press Finish 2.4  Create a Connection Factory Services > Messaging > JMS Modules Select TestJMSModule  and press New Select Connection Factory  and Next Name: TestConnectionFactory JNDI Name: jms/TestConnectionFactory Leave the other values at default On the Targets page, select the Advanced Targeting  button and select TestSubdeployment Press Finish The connection factory should be listed on the following page with TestSubdeployment and TestJMSServer as the target. 2.5 Create a JMS Queue Services > Messaging > JMS Modules Select TestJMSModule  and press New Select Queue and Next Name: TestJMSQueueJNDI Name: jms/TestJMSQueueTemplate: NonePress Next Subdeployments: TestSubdeployment Finish The TestJMSQueue should be listed on the following page with TestSubdeployment and TestJMSServer. Confirm the resources for the TestJMSModule. Using the Domain Structure tree, navigate to soa_domain > Services > Messaging > JMS Modules then select TestJMSModule You should see the following resources The JMS queue is now complete and can be accessed using the JNDI names jms/TestConnectionFactory andjms/TestJMSQueue. In the following blog post in this series, I will show you how to write a message to this queue, using the WebLogic sample Java program QueueSend.java.

• SQLAuthority News – Author Visit Review – TechMela Nepal – March 29-30, 2010

  - by pinaldave

  I was very fortunate to attend TechMela at Kathmandu, Nepal on 29th and 30th of March 2010. I would like to thank Allen Bailochan Tuladhar from Microsoft MDP Nepal for inviting me. Allen is a person with seemingly infinite energy and unlimited passion for Microsoft Technology. If you get an opportunity to spend just one hour with him, you will surely be more enthusiastic with regards to Microsoft Technology. And, I was lucky enough that I was able to spend about a total of 9 days with him in Kathmandu, working along with him in the Tech Community. TechMela Nepal Pinal at TechMela, Nepal TechMela is considered as one of the biggest events in Nepal, having been organized by Microsoft MDP Nepal. This event was attended by around 500 students and hundreds of Tech professionals. The event was handled very professionally and at very large scale. Every minor detail was properly planned and obviously thought out well. There were around 50+ volunteers from MS MDP who were monitoring this event systematically to make sure the event would run as smooth as planned. Attendees in Geek T-Shirts During this event, I was delighted to meet David Lim of Microsoft Singapore. He is very passionate in working for Microsoft Technology, as well as building deep relations with the Community. I was fortunate to spend my entire afternoon with him during the sight-seeing trip. We discussed various MS technologies and their community’s adoption as well as the way how each of us can be a part of the community activity. He also delivered excellent keynotes at the event. I must say that this is one of the most enjoyable keynotes I have ever attended. It was interesting and interactive, and I must say that I had the 70s feelings with all the fonts and graphics. I still remember him saying, “Yeah, I was a student and I know you.” Allen Tuladhar, David Lim, Pinal Dave and Guests After the keynote, everybody cheered when Allen came on stage to talk about the event and to introduce the agenda for the next two days. I must say that Allen is one of the most well-known people in Nepal. I was impressed with his popularity, and to prove this, when he got on the stage he had to wait for a long full minute before he was able to greet “Welcome” while the attendees were clapping and cheering. Technology Panelist at Techmela Kathmandu, Nepal This event was blessed with the top-of-the-top officials of various IT industries, Nepal ministries and the US Embassy. All the prominent personalities were present for panel discussion on the stage. The talk was done on various subjects. Also, the energy level which was set by Allen really echoed in the audience as they asked certain questions on different global as well local IT-related questions. The panel discussion really was discussion instead of usual monologue of one person. Pinal Dave presending at TechMela Kathmandu, Nepal This was a two-day event and my session was on either of the day. I had a great participation from the audience on both days. The place where the event was organized had a capacity of around 500+ audience. Both of my sessions were heavily attended and volunteers did a fabulous job helping the attendees find empty seats or arrange some additional seats. I was overwhelmed with the interaction I have received in the large hall. Attendees were not so shy to express their thoughts, so both the sessions were followed up by top notch one-on-one conversations for a couple of hours. Pinal Dave presending at TechMela Kathmandu, Nepal Pinal Dave presending at TechMela Kathmandu, Nepal Pinal Dave presending at TechMela Kathmandu, Nepal There are many questions that I have received during the event, and many of them can be interesting for all of us here so I will write detailed blog posts on these subjects. I also tried to participate in the gaming activities held at the event, but I felt I was kind of lost even if I was only playing for the very first minutes. This made me realize that I am really getting old for video games. Allen presending at TechMela Kathmandu, Nepal Allen’s session on Digital Photography was very impressive as he demonstrated so many features of the Windows Live Product that at one point I felt he is MVP for Windows Live. In fact, he demonstrated how all the Microsoft products work together to give users an excellent desktop experience; no wonder he is an MVP for Windows Desktop Experience. Pinal Dave presending at TechMela Kathmandu, Nepal Any event has two common dilemmas – food and logistics. However, this event had excellent food and state-of-the-art organization. I was very glad that this two-day event turned out to be one of the most successful events in Nepal. I also noticed that almost all attendees rate their experience as beyond expectation and truly exceptional. Pinal Dave and Allen Bailochan Tuladhar If you ever get invited by Allen in any of his event, I strongly suggest that you drop all your plans and scheduled stuff, and accept his invitation. For sure, the event will be a very memorable one and would be your once-in-a-lifetime experience.

• Announcing SonicAgile – An Agile Project Management Solution

  - by Stephen.Walther

  I’m happy to announce the public release of SonicAgile – an online tool for managing software projects. You can register for SonicAgile at www.SonicAgile.com and start using it with your team today. SonicAgile is an agile project management solution which is designed to help teams of developers coordinate their work on software projects. SonicAgile supports creating backlogs, scrumboards, and burndown charts. It includes support for acceptance criteria, story estimation, calculating team velocity, and email integration. In short, SonicAgile includes all of the tools that you need to coordinate work on a software project, get stuff done, and build great software. Let me discuss each of the features of SonicAgile in more detail. SonicAgile Backlog You use the backlog to create a prioritized list of user stories such as features, bugs, and change requests. Basically, all future work planned for a product should be captured in the backlog. We focused our attention on designing the user interface for the backlog. Because the main function of the backlog is to prioritize stories, we made it easy to prioritize a story by just drag and dropping the story from one location to another. We also wanted to make it easy to add stories from the product backlog to a sprint backlog. A sprint backlog contains the stories that you plan to complete during a particular sprint. To add a story to a sprint, you just drag the story from the product backlog to the sprint backlog. Finally, we made it easy to track team velocity — the average amount of work that your team completes in each sprint. Your team’s average velocity is displayed in the backlog. When you add too many stories to a sprint – in other words, you attempt to take on too much work – you are warned automatically: SonicAgile Scrumboard Every workday, your team meets to have their daily scrum. During the daily scrum, you can use the SonicAgile Scrumboard to see (at a glance) what everyone on the team is working on. For example, the following scrumboard shows that Stephen is working on the Fix Gravatar Bug story and Pete and Jane have finished working on the Product Details Page story: Every story can be broken into tasks. For example, to create the Product Details Page, you might need to create database objects, do page design, and create an MVC controller. You can use the Scrumboard to track the state of each task. A story can have acceptance criteria which clarify the requirements for the story to be done. For example, here is how you can specify the acceptance criteria for the Product Details Page story: You cannot close a story — and remove the story from the list of active stories on the scrumboard — until all tasks and acceptance criteria associated with the story are done. SonicAgile Burndown Charts You can use Burndown charts to track your team’s progress. SonicAgile supports Release Burndown, Sprint Burndown by Task Estimates, and Sprint Burndown by Story Points charts. For example, here’s a sample of a Sprint Burndown by Story Points chart: The downward slope shows the progress of the team when closing stories. The vertical axis represents story points and the horizontal axis represents time. Email Integration SonicAgile was designed to improve your team’s communication and collaboration. Most stories and tasks require discussion to nail down exactly what work needs to be done. The most natural way to discuss stories and tasks is through email. However, you don’t want these discussions to get lost. When you use SonicAgile, all email discussions concerning a story or a task (including all email attachments) are captured automatically. At any time in the future, you can view all of the email discussion concerning a story or a task by opening the Story Details dialog: Why We Built SonicAgile We built SonicAgile because we needed it for our team. Our consulting company, Superexpert, builds websites for financial services, startups, and large corporations. We have multiple teams working on multiple projects. Keeping on top of all of the work that needs to be done to complete a software project is challenging. You need a good sense of what needs to be done, who is doing it, and when the work will be done. We built SonicAgile because we wanted a lightweight project management tool which we could use to coordinate the work that our team performs on software projects. How We Built SonicAgile We wanted SonicAgile to be easy to use, highly scalable, and have a highly interactive client interface. SonicAgile is very close to being a pure Ajax application. We built SonicAgile using ASP.NET MVC 3, jQuery, and Knockout. We would not have been able to build such a complex Ajax application without these technologies. Almost all of our MVC controller actions return JSON results (While developing SonicAgile, I would have given my left arm to be able to use the new ASP.NET Web API). The controller actions are invoked from jQuery Ajax calls from the browser. We built SonicAgile on Windows Azure. We are taking advantage of SQL Azure, Table Storage, and Blob Storage. Windows Azure enables us to scale very quickly to handle whatever demand is thrown at us. Summary I hope that you will try SonicAgile. You can register at www.SonicAgile.com (there’s a free 30-day trial). The goal of SonicAgile is to make it easier for teams to get more stuff done, work better together, and build amazing software. Let us know what you think!

• Linux-Containers — Part 1: Overview

  - by Lenz Grimmer

  "Containers" by Jean-Pierre Martineau (CC BY-NC-SA 2.0). Linux Containers (LXC) provide a means to isolate individual services or applications as well as of a complete Linux operating system from other services running on the same host. To accomplish this, each container gets its own directory structure, network devices, IP addresses and process table. The processes running in other containers or the host system are not visible from inside a container. Additionally, Linux Containers allow for fine granular control of resources like RAM, CPU or disk I/O. Generally speaking, Linux Containers use a completely different approach than "classicial" virtualization technologies like KVM or Xen (on which Oracle VM Server for x86 is based on). An application running inside a container will be executed directly on the operating system kernel of the host system, shielded from all other running processes in a sandbox-like environment. This allows a very direct and fair distribution of CPU and I/O-resources. Linux containers can offer the best possible performance and several possibilities for managing and sharing the resources available. Similar to Containers (or Zones) on Oracle Solaris or FreeBSD jails, the same kernel version runs on the host as well as in the containers; it is not possible to run different Linux kernel versions or other operating systems like Microsoft Windows or Oracle Solaris for x86 inside a container. However, it is possible to run different Linux distribution versions (e.g. Fedora Linux in a container on top of an Oracle Linux host), provided it supports the version of the Linux kernel that runs on the host. This approach has one caveat, though - if any of the containers causes a kernel crash, it will bring down all other containers (and the host system) as well. For example, Oracle's Unbreakable Enterprise Kernel Release 2 (2.6.39) is supported for both Oracle Linux 5 and 6. This makes it possible to run Oracle Linux 5 and 6 container instances on top of an Oracle Linux 6 system. Since Linux Containers are fully implemented on the OS level (the Linux kernel), they can be easily combined with other virtualization technologies. It's certainly possible to set up Linux containers within a virtualized Linux instance that runs inside Oracle VM Server for Oracle VM Virtualbox. Some use cases for Linux Containers include: Consolidation of multiple separate Linux systems on one server: instances of Linux systems that are not performance-critical or only see sporadic use (e.g. a fax or print server or intranet services) do not necessarily need a dedicated server for their operations. These can easily be consolidated to run inside containers on a single server, to preserve energy and rack space. Running multiple instances of an application in parallel, e.g. for different users or customers. Each user receives his "own" application instance, with a defined level of service/performance. This prevents that one user's application could hog the entire system and ensures, that each user only has access to his own data set. It also helps to save main memory — if multiple instances of a same process are running, the Linux kernel can share memory pages that are identical and unchanged across all application instances. This also applies to shared libraries that applications may use, they are generally held in memory once and mapped to multiple processes. Quickly creating sandbox environments for development and testing purposes: containers that have been created and configured once can be archived as templates and can be duplicated (cloned) instantly on demand. After finishing the activity, the clone can safely be discarded. This allows to provide repeatable software builds and test environments, because the system will always be reset to its initial state for each run. Linux Containers also boot significantly faster than "classic" virtual machines, which can save a lot of time when running frequent build or test runs on applications. Safe execution of an individual application: if an application running inside a container has been compromised because of a security vulnerability, the host system and other containers remain unaffected. The potential damage can be minimized, analyzed and resolved directly from the host system. Note: Linux Containers on Oracle Linux 6 with the Unbreakable Enterprise Kernel Release 2 (2.6.39) are still marked as Technology Preview - their use is only recommended for testing and evaluation purposes. The Open-Source project "Linux Containers" (LXC) is driving the development of the technology behind this, which is based on the "Control Groups" (CGroups) and "Name Spaces" functionality of the Linux kernel. Oracle is actively involved in the Linux Containers development and contributes patches to the upstream LXC code base. Control Groups provide means to manage and monitor the allocation of resources for individual processes or process groups. Among other things, you can restrict the maximum amount of memory, CPU cycles as well as the disk and network throughput (in MB/s or IOP/s) that are available for an application. Name Spaces help to isolate process groups from each other, e.g. the visibility of other running processes or the exclusive access to a network device. It's also possible to restrict a process group's access and visibility of the entire file system hierarchy (similar to a classic "chroot" environment). CGroups and Name Spaces provide the foundation on which Linux containers are based on, but they can actually be used independently as well. A more detailed description of how Linux Containers can be created and managed on Oracle Linux will be explained in the second part of this article.

• Installing Visual Studio Team Foundation Server Service Pack 1

  - by Martin Hinshelwood

  As has become customary when the product team releases a new patch, SP or version I like to document the install. Although I had no errors on my main computer, my netbook did have problems. Although I am not ready to call it a Service Pack problem just yet! Update 2011-03-10 – Running the Team Foundation Server 2010 Service Pack 1 install a second time worked As per Brian's post I am installing the Team Foundation Server Service Pack first and indeed as this is a single server local deployment I need to install both. If I only install one it will leave the other product broken. This however does not affect you if you are running Visual Studio and Team Foundation Server on separate computers as is normal in a production deployment. Main workhorse I will be installing the service pack first on my main computer as I want to actually use it here. Figure: My main workhorse I will also be installing this on my netbook which is obviously of significantly lower spec, but I will do that one after. Although, as always I had my fingers crossed, I was not really worried. Figure: KB2182621 Compared to Visual Studio there are not really a lot of components to update. Figure: TFS 2010 and SQL 2008 are the main things to update There is no “web” installer for the Team Foundation Server 2010 Service Pack, but that is ok as most people will be installing it on a production server and will want to have everything local. I would have liked a Web installer, but the added complexity for the product team is not work the capability for a 500mb patch. Figure: There is currently no way to roll SP1 and RTM together Figure: No problems with the file verification, phew Figure: Although the install took a while, it progressed smoothly   Figure: I always like a success screen Well, as far as the install is concerned everything is OK, but what about TFS? Can I still connect and can I still administer it. Figure: Service Pack 1 is reflected correctly in the Administration Console I am confident that there are no major problems with TFS on my system and that it has been updated to SP1. I can do all of the things that I used before with ease, and with the new features detailed by Brian I think I will be happy. Netbook The great god Murphy has stuck, and my poor wee laptop spat the Team Foundation Server 2010 Service Pack 1 out so fast it hit me on the back of the head. That will teach me for not looking… Figure: “Installation did not succeed” I am pretty sure should not be all caps! On examining the file I found that everything worked, except the actual Team Foundation Server 2010 serving step. Action: System Requirement Checks...

Figure: Error log for Team Foundation Server 2010 install shows a failure As there is really no information in this log as to why the installation failed so I checked the event log on that box. Figure: There are hundreds of errors and it actually looks like there are more problems than a failed Service Pack I am going to just run it again and see if it was because the netbook was slow to catch on to the update. Hears hoping, but even if it fails, I would question the installation of Windows (PDC laptop original install) before I question the Service Pack Figure: Second run through was successful I don’t know if the laptop was just slow, or what… Did you get this error? If you did I will push this to the product team as a problem, but unless more people have this sort of error, I will just look to write this off as a corrupted install of Windows and reinstall.

• 8 Backup Tools Explained for Windows 7 and 8

  - by Chris Hoffman

  Backups on Windows can be confusing. Whether you’re using Windows 7 or 8, you have quite a few integrated backup tools to think about. Windows 8 made quite a few changes, too. You can also use third-party backup software, whether you want to back up to an external drive or back up your files to online storage. We won’t cover third-party tools here — just the ones built into Windows. Backup and Restore on Windows 7 Windows 7 has its own Backup and Restore feature that lets you create backups manually or on a schedule. You’ll find it under Backup and Restore in the Control Panel. The original version of Windows 8 still contained this tool, and named it Windows 7 File Recovery. This allowed former Windows 7 users to restore files from those old Windows 7 backups or keep using the familiar backup tool for a little while. Windows 7 File Recovery was removed in Windows 8.1. System Restore System Restore on both Windows 7 and 8 functions as a sort of automatic system backup feature. It creates backup copies of important system and program files on a schedule or when you perform certain tasks, such as installing a hardware driver. If system files become corrupted or your computer’s software becomes unstable, you can use System Restore to restore your system and program files from a System Restore point. This isn’t a way to back up your personal files. It’s more of a troubleshooting feature that uses backups to restore your system to its previous working state. Previous Versions on Windows 7 Windows 7′s Previous Versions feature allows you to restore older versions of files — or deleted files. These files can come from backups created with Windows 7′s Backup and Restore feature, but they can also come from System Restore points. When Windows 7 creates a System Restore point, it will sometimes contain your personal files. Previous Versions allows you to extract these personal files from restore points. This only applies to Windows 7. On Windows 8, System Restore won’t create backup copies of your personal files. The Previous Versions feature was removed on Windows 8. File History Windows 8 replaced Windows 7′s backup tools with File History, although this feature isn’t enabled by default. File History is designed to be a simple, easy way to create backups of your data files on an external drive or network location. File History replaces both Windows 7′s Backup and Previous Versions features. Windows System Restore won’t create copies of personal files on Windows 8. This means you can’t actually recover older versions of files until you enable File History yourself — it isn’t enabled by default. System Image Backups Windows also allows you to create system image backups. These are backup images of your entire operating system, including your system files, installed programs, and personal files. This feature was included in both Windows 7 and Windows 8, but it was hidden in the preview versions of Windows 8.1. After many user complaints, it was restored and is still available in the final version of Windows 8.1 — click System Image Backup on the File History Control Panel. Storage Space Mirroring Windows 8′s Storage Spaces feature allows you to set up RAID-like features in software. For example, you can use Storage Space to set up two hard disks of the same size in a mirroring configuration. They’ll appear as a single drive in Windows. When you write to this virtual drive, the files will be saved to both physical drives. If one drive fails, your files will still be available on the other drive. This isn’t a good long-term backup solution, but it is a way of ensuring you won’t lose important files if a single drive fails. Microsoft Account Settings Backup Windows 8 and 8.1 allow you to back up a variety of system settings — including personalization, desktop, and input settings. If you’re signing in with a Microsoft account, OneDrive settings backup is enabled automatically. This feature can be controlled under OneDrive > Sync settings in the PC settings app. This feature only backs up a few settings. It’s really more of a way to sync settings between devices. OneDrive Cloud Storage Microsoft hasn’t been talking much about File History since Windows 8 was released. That’s because they want people to use OneDrive instead. OneDrive — formerly known as SkyDrive — was added to the Windows desktop in Windows 8.1. Save your files here and they’ll be stored online tied to your Microsoft account. You can then sign in on any other computer, smartphone, tablet, or even via the web and access your files. Microsoft wants typical PC users “backing up” their files with OneDrive so they’ll be available on any device. You don’t have to worry about all these features. Just choose a backup strategy to ensure your files are safe if your computer’s hard disk fails you. Whether it’s an integrated backup tool or a third-party backup application, be sure to back up your files.

• Computer Networks UNISA - Chap 12 &ndash; Networking Security

  - by MarkPearl

  After reading this section you should be able to Identify security risks in LANs and WANs and design security policies that minimize risks Explain how physical security contributes to network security Discuss hardware and design based security techniques Understand methods of encryption such as SSL and IPSec, that can secure data in storage and in transit Describe how popular authentication protocols such as RADIUS< TACACS,Kerberos, PAP, CHAP, and MS-CHAP function Use network operating system techniques to provide basic security Understand wireless security protocols such as WEP, WPA and 802.11i Security Audits Before spending time and money on network security, examine your networks security risks – rate and prioritize risks. Different organizations have different levels of network security requirements. Security Risks Not all security breaches result from a manipulation of network technology – there are human factors that can play a role as well. The following categories are areas of considerations… Risks associated with People Risks associated with Transmission and Hardware Risks associated with Protocols and Software Risks associated with Internet Access An effective security policy A security policy identifies your security goals, risks, levels of authority, designated security coordinator and team members, responsibilities for each team member, and responsibilities for each employee. In addition it specifies how to address security breaches. It should not state exactly which hardware, software, architecture, or protocols will be used to ensure security, nor how hardware or software will be installed and configured. A security policy must address an organizations specific risks. to understand your risks, you should conduct a security audit that identifies vulnerabilities and rates both the severity of each threat and its likelihood of occurring. Security Policy Content Security policy content should… Policies for each category of security Explain to users what they can and cannot do and how these measures protect the networks security Should define what confidential means to the organization Response Policy A security policy should provide for a planned response in the event of a security breach. The response policy should identify the members of a response team, all of whom should clearly understand the the security policy, risks, and measures in place. Some of the roles concerned could include… Dispatcher – the person on call who first notices the breach Manager – the person who coordinates the resources necessary to solve the problem Technical Support Specialist – the person who focuses on solving the problem Public relations specialist – the person who acts as the official spokesperson for the organization Physical Security An important element in network security is restricting physical access to its components. There are various techniques for this including locking doors, security people at access points etc. You should identify the following… Which rooms contain critical systems or data and must be secured Through what means might intruders gain access to these rooms How and to what extent are authorized personnel granted access to these rooms Are authentication methods such as ID cards easy to forge etc. Security in Network Design The optimal way to prevent external security breaches from affecting you LAN is not to connect your LAN to the outside world at all. The next best protection is to restrict access at every point where your LAN connects to the rest of the world. Router Access List – can be used to filter or decline access to a portion of a network for certain devices. Intrusion Detection and Prevention While denying someone access to a section of the network is good, it is better to be able to detect when an attempt has been made and notify security personnel. This can be done using IDS (intrusion detection system) software. One drawback of IDS software is it can detect false positives – i.e. an authorized person who has forgotten his password attempts to logon. Firewalls A firewall is a specialized device, or a computer installed with specialized software, that selectively filters or blocks traffic between networks. A firewall typically involves a combination of hardware and software and may reside between two interconnected private networks. The simplest form of a firewall is a packet filtering firewall, which is a router that examines the header of every packet of data it receives to determine whether that type of packet is authorized to continue to its destination or not. Firewalls can block traffic in and out of a LAN. NOS (Network Operating System) Security Regardless of the operating system, generally every network administrator can implement basic security by restricting what users are authorized to do on a network. Some of the restrictions include things related to Logons – place, time of day, total time logged in, etc Passwords – length, characters used, etc Encryption Encryption is the use of an algorithm to scramble data into a format that can be read only by reversing the algorithm. The purpose of encryption is to keep information private. Many forms of encryption exist and new ways of cracking encryption are continually being invented. The following are some categories of encryption… Key Encryption PGP (Pretty Good Privacy) SSL (Secure Sockets Layer) SSH (Secure Shell) SCP (Secure CoPy) SFTP (Secure File Transfer Protocol) IPSec (Internet Protocol Security) For a detailed explanation on each section refer to pages 596 to 604 of textbook Authentication Protocols Authentication protocols are the rules that computers follow to accomplish authentication. Several types exist and the following are some of the common authentication protocols… RADIUS and TACACS PAP (Password Authentication Protocol) CHAP and MS-CHAP EAP (Extensible Authentication Protocol) 802.1x (EAPoL) Kerberos Wireless Network Security Wireless transmissions are particularly susceptible to eavesdropping. The following are two wireless network security protocols WEP WPA
