  • php: parsing and converting array structure

    - by mwb
    I need to convert one array structure into another array structure. I hope someone will find it worthy their time to show how this could be done in a simple manner. It's a little above my array manipulation skills. The structure we start out with looks like this: $cssoptions = array( array( 'group' => 'Measurements' , 'selector' => '#content' , 'rule' => 'width' , 'value' => '200px' ) // end data set , array( 'group' => 'Measurements' , 'selector' => '#content' , 'rule' => 'margin-right' , 'value' => '20px' ) // end data set , array( 'group' => 'Colors' , 'selector' => '#content' , 'rule' => 'color' , 'value' => '#444' ) // end data set , array( 'group' => 'Measurements' , 'selector' => '.sidebar' , 'rule' => 'margin-top' , 'value' => '10px' ) // end data set ); // END $cssoptions It's a collection of discreet datasets, each consisting of an array that holds two key = value pairs describing a 'css-rule' and a 'css-rule-value'. Further, each dataset holds a key = value pair describing the 'css-selector-group' that the 'css-rule' should blong to, and a key = value pair describing a 'rule-group' that should be used for structuring the rendering of the final css into a neat css code block arranged by the kind of properties they describe (colors, measurement, typography etc..) Now, I need to parse that, and turn it into a new structure, where the: 'rule' => 'rule-name' , 'value' => 'value-string' for each dataset is converted into: 'rule-name' => 'value-string' ..and then placed into a new array structure where all 'rule-name' = 'value-string' pairs should be aggregated under the respective 'selector-values' Like this: '#content' => array( 'width' => '200px' , 'margin-right' => '20px' ) // end selecor block ..and finally all those blocks should be grouped under their respective 'style-groups', creating a final resulting array structure like this: $css => array( 'Measurements' => array( '#content' => array( 'width' => '200px' , 'margin-right' => '20px' ) // end selecor block , '.sidebar' => array( 'margin-top' => '10px' ) // end selector block ) // end rule group , 'Colors' => array( '#content' => array( 'color' => '#444' ) // end selector block ) // end rule group ); // end css

  • Intermittent wired network issues in 14.04

    Since yesterday, my wired network connection has been dropping for a couple of seconds every 30 seconds or so. To my knowledge, I had not made any changes to my network.

  • WSUS 3.0 SP2 installation fails at "configuring database" step.

    - by flashkube
    Attempting to install WSUS 3.0 SP2 on a Windows Server 2003 Enterprise system. I'm asking the setup to create a new database on one of our existing SQL Server 2005 systems. When the setup gets to the "configuring database" step it stops and throws "There is a problem with this Windows Installer package. A program run as part of the setup did not finish as expected. Contact your support personnel or package vendor." The two logs it suggests I look at are below. I'm not seeing any errors that mean anything to me. Any direction you can give will be greatly appreciated.

  • http request via iptables --to-destination ip redirect results in no response

    - by Wouter Vegter
    I have two Ubuntu servers with each having their own ip addresses. Let's call them server1 and server2, having respectively ip 1.1.1.1 and 2.2.2.2 I have a nginx running on server2. The sole purpose I want server1 to have is to redirect all incoming http (so port 80) requests to server2 without clients noticing that their request is being redirected. I tried the following command on server1: iptables -t nat -A PREROUTING -p tcp --dport 80 -j DNAT --to-destination 2.2.2.2 But when I enter 1.1.1.1 in my browser I get no respond: the page keeps trying to load without giving any message or error message (I get a time-out after 2-3 mins). But when I do remove the above iptables rule I immediately do get a "page not found error" when I enter 1.1.1.1 in my browser; so something is working but not as it should: when I enter 1.1.1.1 I want the html page to load that is hosted on 2.2.2.2 Because when i enter 2.2.2.2 in my browser I do see the webpage loaded. Could anyone please help me with this? I am searching quite some time (on severfault & Google) on this now so that's why I ask. Many thanks for reading my question! Update: Thank you all for you information. Unfortunately I still get no response I have the following iptables configuration: root@ip-10-48-238-216:/home/ubuntu# sudo iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination root@ip-10-48-238-216:/home/ubuntu# sudo iptables -t nat -L Chain PREROUTING (policy ACCEPT) target prot opt source destination DNAT tcp -- anywhere anywhere tcp dpt:www to:2.2.2.2 Chain OUTPUT (policy ACCEPT) target prot opt source destination Chain POSTROUTING (policy ACCEPT) target prot opt source destination When i run tcpdump and do request via chrome to 1.1.1.1 i get the following root@ip-10-48-238-216:/home/ubuntu# sudo tcpdump -i eth0 port 80 -vv tcpdump: listening on eth0, link-type EN10MB (Ethernet), capture size 65535 bytes 13:56:18.346625 IP (tos 0x0, ttl 52, id 12055, offset 0, flags [DF], proto TCP (6), length 60) 212-123-161-112.ip.telfort.nl.16386 ip-10-48-238-216.eu-west-1.compute.internal.www: Flags [S], cksum 0xb398 (correct), seq 2639758575, win 5840, options [mss 1460,sackOK,TS val 1223672 ecr 0,nop,wscale 6], length 0 13:56:18.346662 IP (tos 0x0, ttl 51, id 12055, offset 0, flags [DF], proto TCP (6), length 60) 212-123-161-112.ip.telfort.nl.16386 ww1dc1.shopreme.com.www: Flags [S], cksum 0x9ee0 (correct), seq 2639758575, win 5840, options [mss 1460,sackOK,TS val 1223672 ecr 0,nop,wscale 6], length 0 13:56:18.598747 IP (tos 0x0, ttl 52, id 10138, offset 0, flags [DF], proto TCP (6), length 60) 212-123-161-112.ip.telfort.nl.16387 ip-10-48-238-216.eu-west-1.compute.internal.www: Flags [S], cksum 0xac40 (correct), seq 2645658541, win 5840, options [mss 1460,sackOK,TS val 1223735 ecr 0,nop,wscale 6], length 0 13:56:18.598777 IP (tos 0x0, ttl 51, id 10138, offset 0, flags [DF], proto TCP (6), length 60) 212-123-161-112.ip.telfort.nl.16387 ww1dc1.shopreme.com.www: Flags [S], cksum 0x9788 (correct), seq 2645658541, win 5840, options [mss 1460,sackOK,TS val 1223735 ecr 0,nop,wscale 6], length 0 ^C 4 packets captured 4 packets received by filter 0 packets dropped by kernel the mentioned address relate to the following 212-123-161-112.ip.telfort.nl.16386 : my personal computer ww1dc1.shopreme.com.www : dns of server2 (2.2.2.2) ip-10-48-238-216.eu-west-1.compute.internal.www : amazon web services ec2 internal address of server1 (1.1.1.1) However, the tcpdump log on server2 (2.2.2.2) stays empty and I get no response back in my browser. I am able to ping from server1 to server2. And net.ipv4.ip_forward is set to 1 and so is /proc/sys/net/ipv4/ip_forward Could there be anything else that is missing?

  • iptables rule(s) to send openvpn traffic from clients over an sshuttle tunnel?

    - by Sam Martin
    I have an Ubuntu 12.04 box with OpenVPN. The VPN is working as expected -- clients can connect, browse the Web, etc. The OpenVPN server IP is 10.8.0.1 on tun0. On that same box, I can use sshuttle to tunnel into another network to access a Web server on 10.10.0.9. sshuttle does its magic using the following iptables commands: iptables -t nat -N sshuttle-12300 iptables -t nat -F sshuttle-12300 iptables -t nat -I OUTPUT 1 -j sshuttle-12300 iptables -t nat -I PREROUTING 1 -j sshuttle-12300 iptables -t nat -A sshuttle-12300 -j REDIRECT --dest 10.10.0.0/24 -p tcp --to-ports 12300 -m ttl ! --ttl 42 iptables -t nat -A sshuttle-12300 -j RETURN --dest 127.0.0.0/8 -p tcp Is it possible to forward traffic from OpenVPN clients over the sshuttle tunnel to the remote Web server? I'd ultimately like to be able to set up any complicated tunneling on the server, and have relatively "dumb" clients (iPad, etc.) be able to access the remote servers via OpenVPN. Below is a basic diagram of the scenario: [Edit: added output from the OpenVPN box] $ sudo iptables -nL -v -t nat Chain PREROUTING (policy ACCEPT 1498 packets, 252K bytes) pkts bytes target prot opt in out source destination 1512 253K sshuttle-12300 all -- * * 0.0.0.0/0 0.0.0.0/0 Chain INPUT (policy ACCEPT 322 packets, 58984 bytes) pkts bytes target prot opt in out source destination Chain OUTPUT (policy ACCEPT 584 packets, 43241 bytes) pkts bytes target prot opt in out source destination 587 43421 sshuttle-12300 all -- * * 0.0.0.0/0 0.0.0.0/0 Chain POSTROUTING (policy ACCEPT 589 packets, 43595 bytes) pkts bytes target prot opt in out source destination 1175 76298 MASQUERADE all -- * eth0 10.8.0.0/24 0.0.0.0/0 Chain sshuttle-12300 (2 references) pkts bytes target prot opt in out source destination 17 1076 REDIRECT tcp -- * * 0.0.0.0/0 10.10.0.0/24 TTL match TTL != 42 redir ports 12300 0 0 RETURN tcp -- * * 0.0.0.0/0 127.0.0.0/8 $ sudo iptables -nL -v -t filter Chain INPUT (policy ACCEPT 97493 packets, 30M bytes) pkts bytes target prot opt in out source destination Chain FORWARD (policy ACCEPT 0 packets, 0 bytes) pkts bytes target prot opt in out source destination 131K 109M ACCEPT all -- * * 0.0.0.0/0 0.0.0.0/0 state RELATED,ESTABLISHED 1370 89160 ACCEPT all -- * * 10.8.0.0/24 0.0.0.0/0 0 0 REJECT all -- * * 0.0.0.0/0 0.0.0.0/0 reject-with icmp-port-unreachable [Edit 2: more OpenVPN server output] $ netstat -r Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface default 192.168.1.1 0.0.0.0 UG 0 0 0 eth0 10.8.0.0 10.8.0.2 255.255.255.0 UG 0 0 0 tun0 10.8.0.2 * 255.255.255.255 UH 0 0 0 tun0 192.168.1.0 * 255.255.255.0 U 0 0 0 eth0 [Edit 3: still more debug output] IP forwarding appears to be enabled correctly on the OpenVPN server: # find /proc/sys/net/ipv4/conf/ -name forwarding -ls -execdir cat {} \; 18926 0 -rw-r--r-- 1 root root 0 Mar 5 13:31 /proc/sys/net/ipv4/conf/all/forwarding 1 18954 0 -rw-r--r-- 1 root root 0 Mar 5 13:31 /proc/sys/net/ipv4/conf/default/forwarding 1 18978 0 -rw-r--r-- 1 root root 0 Mar 5 13:31 /proc/sys/net/ipv4/conf/eth0/forwarding 1 19003 0 -rw-r--r-- 1 root root 0 Mar 5 13:31 /proc/sys/net/ipv4/conf/lo/forwarding 1 19028 0 -rw-r--r-- 1 root root 0 Mar 5 13:31 /proc/sys/net/ipv4/conf/tun0/forwarding 1 Client routing table: $ netstat -r Routing tables Internet: Destination Gateway Flags Refs Use Netif Expire 0/1 10.8.0.5 UGSc 8 48 tun0 default 192.168.1.1 UGSc 2 1652 en1 10.8.0.1/32 10.8.0.5 UGSc 1 0 tun0 10.8.0.5 10.8.0.6 UHr 13 0 tun0 10.10.0/24 10.8.0.5 UGSc 0 0 tun0 <snip> Traceroute from client: $ traceroute 10.10.0.9 traceroute to 10.10.0.9 (10.10.0.9), 64 hops max, 52 byte packets 1 10.8.0.1 (10.8.0.1) 5.403 ms 1.173 ms 1.086 ms 2 192.168.1.1 (192.168.1.1) 4.693 ms 2.110 ms 1.990 ms 3 l100.my-verizon-garbage (client-ext-ip) 7.453 ms 7.089 ms 6.248 ms 4 * * * 5 10.10.0.9 (10.10.0.9) 14.915 ms !N * 6.620 ms !N

  • Can not open port 3306 on Ubuntu using iptables

    - by user94626
    I am trying to open port 3306 (for remote mysql connections) on my ubuntu 12.04 server machine but for the life of me can't get the damned thing to work!

I suspect since the new rule is being appended at the end it will have no effect as there appears to be a "reject all" sort of rule before it. If this is the case, how to make sure the new rule is added in the right order? Otherwise, what am I missing? Please help.

  • Mauritius Software Craftsmanship Community

    There we go! I finally managed to push myself forward and pick up an old, actually too old, idea since I ever arrived here in Mauritius more than six years ago. I'm talking about a community for all kind of ICT connected people. In the past (back in Germany), I used to be involved in various community activities. For example, I was part of the Microsoft Community Leader/Influencer Program (CLIP) in Germany due to an FAQ on Visual FoxPro, actually Active FoxPro Pages (AFP) to be more precise. Then in 2003/2004 I addressed the responsible person of the dFPUG user group in Speyer in order to assist him in organising monthly user group meetings. Well, he handed over management completely, and attended our meetings regularly. Why did it take you so long? Well, I don't want to bother you with the details but short version is that I was too busy on either job (building up new companies) or private life (got married and we have two lovely children, eh 'monsters') or even both. But now is the time where I was starting to look for new fields given the fact that I gained some spare time. My businesses are up and running, the kids are in school, and I am finally in a position where I can commit myself again to community activities. And I love to do that! Why a new user group? Good question... And 'easy' to answer. Since back in 2007 I did my usual research, eh Google searches, to see whether there existing user groups in Mauritius and in which field of interest. And yes, there are! If I recall this correctly, then there are communities for PHP, Drupal, Python (just recently), Oracle, and Linux (which used to be even two). But... either they do not exist anymore, they are dormant, or there is only a low heart-beat, frankly speaking. And yes, I went to meetings of the Linux User Group Meta (Mauritius) back in 2010/2011 and just recently. I really like the setup and the way the LUGM is organised. It's just that I have a slightly different point of view on how a user group or community should organise itself and how to approach future members. Don't get me wrong, I'm not criticizing others doing a very good job, I'm only saying that I'd like to do it differently. The last meeting of the LUGM was awesome; read my feedback about it. Ok, so what's up with 'Mauritius Software Craftsmanship Community' or short: MSCC? As I've already written in my article on 'Communities - The importance of exchange and discussion' I think it is essential in a world of IT to stay 'connected' with a good number of other people in the same field. There is so much dynamic and every day's news that it is almost impossible to keep on track with all of them. The MSCC is going to provide a common platform to exchange experience and share knowledge between each other. You might be a newbie and want to know what to expect working as a software developer, or as a database administrator, or maybe as an IT systems administrator, or you're an experienced geek that loves to share your ideas or solutions that you implemented to solve a specific problem, or you're the business (or HR) guy that is looking for 'fresh' blood to enforce your existing team. Or... you're just interested and you'd like to communicate with like-minded people. Meetup of 26.06.2013 @ L'arabica: Of course there are laptops around. Free WiFi, power outlet, coffee, code and Linux in one go. The MSCC is technology-agnostic and spans an umbrella over any kind of technology. Simply because you can't ignore other technologies anymore in a connected IT world as we have. A front-end developer for iOS applications should have the chance to connect with a Python back-end coder and eventually with a DBA for MySQL or PostgreSQL and exchange their experience. Furthermore, I'm a huge fan of cross-platform development, and it is very pleasant to have pure Web developers - with all that HTML5, CSS3, JavaScript and JS libraries stuff - and passionate C# or Java coders at the same table. This diversity of knowledge can assist and boost your personal situation. And last but not least, there are projects and open positions 'flying' around... People might like to hear others opinion about an employer or get new impulses on how to tackle down an issue at their workspace, etc. This is about community. And that's how I see the MSCC in general - free of any limitations be it by programming language or technology. Having the chance to exchange experience and to discuss certain aspects of technology saves you time and money, and it's a pleasure to enjoy. Compared to dusty books and remote online resources. It's human! Organising meetups (meetings, get-together, gatherings - you name it!) As of writing this article, the MSCC is currently meeting every Wednesday for the weekly 'Code & Coffee' session at various locations (suggestions are welcome!) in Mauritius. This might change in the future eventually but especially at the beginning I think it is very important to create awareness in the Mauritian IT world. Yes, we are here! Come and join us! ;-) The MSCC's main online presence is located at Meetup.com because it allows me to handle the organisation of events and meeting appointments very easily, and any member can have a look who else is involved so that an exchange of contacts is given at any time. In combination with the other entities (G+ Communities, FB Pages or in Groups) I advertise and manage all future activities here: Mauritius Software Craftsmanship Community This is a community for those who care and are proud of what they do. For those developers, regardless how experienced they are, who want to improve and master their craft. This is a community for those who believe that being average is just not good enough. I know, there are not many 'craftsmen' yet but it's a start... Let's see how it looks like by the end of the year. There are free smartphone apps for Android and iOS from Meetup.com that allow you to keep track of meetings and to stay informed on latest updates. And last but not least, there is a Trello workspace to collect and share ideas and provide downloads of slides, etc. Trello is also available as free smartphone app. Sharing is caring! As mentioned, the #MSCC is present in various social media networks in order to cover as many people as possible here in Mauritius. Following is an overview of the current networks: Twitter - Latest updates and quickies Google+ - Community channel Facebook - Community Page LinkedIn - Community Group Trello - Collaboration workspace to share and develop ideas Hopefully, this covers the majority of computer-related people in Mauritius. Please spread the word about the #MSCC between your colleagues, your friends and other interested 'geeks'. Your future looks bright Running and participating in a user group or any kind of community usually provides quite a number of advantages for anyone. On the one side it is very joyful for me to organise appointments and get in touch with people that might be interested to present a little demo of their projects or their recent problems they had to tackle down, and on the other side there are lots of companies that have various support programs or sponsorships especially tailored for user groups. At the moment, I already have a couple of gimmicks that I would like to hand out in small contests or raffles during one of the upcoming meetings, and as said, companies provide all kind of goodies, books free of charge, or sometimes even licenses for communities. Meeting other software developers or IT guys also opens up your point of view on the local market and there might be interesting projects or job offers available, too. A community like the Mauritius Software Craftsmanship Community is great for freelancers, self-employed, students and of course employees. Meetings will be organised on a regular basis, and I'm open to all kind of suggestions from you. Please leave a comment here in blog or join the conversations in the above mentioned social networks. Let's get this community up and running, my fellow Mauritians! Recent updates The MSCC is now officially participating in the O'Reilly UK User Group programm and we are allowed to request review or recension copies of recent titles. Additionally, we have a discount code for any books or ebooks that you might like to order on shop.oreilly.com. More applications for user group sponsorship programms are pending and I'm looking forward to a couple of announcement very soon. And... we need some kind of 'corporate identity' - Over at the MSCC website there is a call for action (or better said a contest with prizes) to create a unique design for the MSCC. This would include a decent colour palette, a logo, graphical banners for Meetup, Google+, Facebook, LinkedIn, etc. and of course badges for our craftsmen to add to their personal blogs and websites. Please spread the word and contribute. Thanks!

  • Communication Between Your PC and Azure VM via Windows Azure Connect

    - by Shaun
    With the new release of the Windows Azure platform there are a lot of new features available. In my previous post I introduced a little bit about one of them, the remote desktop access to azure virtual machine. Now I would like to talk about another cool stuff – Windows Azure Connect.   What’s Windows Azure Connect I would like to quote the definition of the Windows Azure Connect in MSDN With Windows Azure Connect, you can use a simple user interface to configure IP-sec protected connections between computers or virtual machines (VMs) in your organization’s network, and roles running in Windows Azure. IP-sec protects communications over Internet Protocol (IP) networks through the use of cryptographic security services. There’s an image available at the MSDN as well that I would like to forward here As we can see, using the Windows Azure Connect the Worker Role 1 and Web Role 1 are connected with the development machines and database servers which some of them are inside the organization some are not. With the Windows Azure Connect, the roles deployed on the cloud could consume the resource which located inside our Intranet or anywhere in the world. That means the roles can connect to the local database, access the local shared resource such as share files, folders and printers, etc.   Difference between Windows Azure Connect and AppFabric It seems that the Windows Azure Connect are duplicated with the Windows Azure AppFabric. Both of them are aiming to solve the problem on how to communication between the resource in the cloud and inside the local network. The table below lists the differences in my understanding. Category Windows Azure Connect Windows Azure AppFabric Purpose An IP-sec connection between the local machines and azure roles. An application service running on the cloud. Connectivity IP-sec, Domain-joint Net Tcp, Http, Https Components Windows Azure Connect Driver Service Bus, Access Control, Caching Usage Azure roles connect to local database server Azure roles use local shared files,  folders and printers, etc. Azure roles join the local AD. Expose the local service to Internet. Move the authorization process to the cloud. Integrate with existing identities such as Live ID, Google ID, etc. with existing local services. Utilize the distributed cache.   And also some scenarios on which of them should be used. Scenario Connect AppFabric I have a service deployed in the Intranet and I want the people can use it from the Internet.   Y I have a website deployed on Azure and need to use a database which deployed inside the company. And I don’t want to expose the database to the Internet. Y   I have a service deployed in the Intranet and is using AD authorization. I have a website deployed on Azure which needs to use this service. Y   I have a service deployed in the Intranet and some people on the Internet can use it but need to be authorized and authenticated.   Y I have a service in Intranet, and a website deployed on Azure. This service can be used from Internet and that website should be able to use it as well by AD authorization for more functionalities. Y Y   How to Enable Windows Azure Connect OK we talked a lot information about the Windows Azure Connect and differences with the Windows Azure AppFabric. Now let’s see how to enable and use the Windows Azure Connect. First of all, since this feature is in CTP stage we should apply before use it. On the Windows Azure Portal we can see our CTP features status under Home, Beta Program page. You can send the apply to join the Beta Programs to Microsoft in this page. After a few days the Microsoft will send an email to you (the email of your Live ID) when it’s available. In my case we can see that the Windows Azure Connect had been activated by Microsoft and then we can click the Connect button on top, or we can click the Virtual Network item from the left navigation bar.   The first thing we need, if it’s our first time to enter the Connect page, is to enable the Windows Azure Connect. After that we can see our Windows Azure Connect information in this page.   Add a Local Machine to Azure Connect As we explained below the Windows Azure Connect can make an IP-sec connection between the local machines and azure role instances. So that we firstly add a local machine into our Azure Connect. To do this we will click the Install Local Endpoint button on top and then the portal will give us an URL. Copy this URL to the machine we want to add and it will download the software to us. This software will be installed in the local machines which we want to join the Connect. After installed there will be a tray-icon appeared to indicate this machine had been joint our Connect. The local application will be refreshed to the Windows Azure Platform every 5 minutes but we can click the Refresh button to let it retrieve the latest status at once. Currently my local machine is ready for connect and we can see my machine in the Windows Azure Portal if we switched back to the portal and selected back Activated Endpoints node.   Add a Windows Azure Role to Azure Connect Let’s create a very simple azure project with a basic ASP.NET web role inside. To make it available on Windows Azure Connect we will open the azure project property of this role from the solution explorer in the Visual Studio, and select the Virtual Network tab, check the Activate Windows Azure Connect. The next step is to get the activation token from the Windows Azure Portal. In the same page there is a button named Get Activation Token. Click this button then the portal will display the token to me. We copied this token and pasted to the box in the Visual Studio tab. Then we deployed this application to azure. After completed the deployment we can see the role instance was listed in the Windows Azure Portal - Virtual Connect section.   Establish the Connect Group The final task is to create a connect group which contains the machines and role instances need to be connected each other. This can be done in the portal very easy. The machines and instances will NOT be connected until we created the group for them. The machines and instances can be used in one or more groups. In the Virtual Connect section click the Groups and Roles node from the left side navigation bar and clicked the Create Group button on top. This will bring up a dialog to us. What we need to do is to specify a group name, description; and then we need to select the local computers and azure role instances into this group. After the Azure Fabric updated the group setting we can see the groups and the endpoints in the page. And if we switch back to the local machine we can see that the tray-icon have been changed and the status turned connected. The Windows Azure Connect will update the group information every 5 minutes. If you find the status was still in Disconnected please right-click the tray-icon and select the Refresh menu to retrieve the latest group policy to make it connected.   Test the Azure Connect between the Local Machine and the Azure Role Instance Now our local machine and azure role instance had been connected. This means each of them can communication to others in IP level. For example we can open the SQL Server port so that our azure role can connect to it by using the machine name or the IP address. The Windows Azure Connect uses IPv6 to connect between the local machines and role instances. You can get the IP address from the Windows Azure Portal Virtual Network section when select an endpoint. I don’t want to take a full example for how to use the Connect but would like to have two very simple tests. The first one would be PING.   When a local machine and role instance are connected through the Windows Azure Connect we can PING any of them if we opened the ICMP protocol in the Filewall setting. To do this we need to run a command line before test. Open the command window on the local machine and the role instance, execute the command as following netsh advfirewall firewall add rule name="ICMPv6" dir=in action=allow enable=yes protocol=icmpv6 Thanks to Jason Chen, Patriek van Dorp, Anton Staykov and Steve Marx, they helped me to enable  the ICMPv6 setting. For the full discussion we made please visit here. You can use the Remote Desktop Access feature to logon the azure role instance. Please refer my previous blog post to get to know how to use the Remote Desktop Access in Windows Azure. Then we can PING the machine or the role instance by specifying its name. Below is the screen I PING my local machine from my azure instance. We can use the IPv6 address to PING each other as well. Like the image following I PING to my role instance from my local machine thought the IPv6 address.   Another example I would like to demonstrate here is folder sharing. I shared a folder in my local machine and then if we logged on the role instance we can see the folder content from the file explorer window.   Summary In this blog post I introduced about another new feature – Windows Azure Connect. With this feature our local resources and role instances (virtual machines) can be connected to each other. In this way we can make our azure application using our local stuff such as database servers, printers, etc. without expose them to Internet.   Hope this helps, Shaun All documents and related graphics, codes are provided "AS IS" without warranty of any kind.

  • Analytic functions – they’re not aggregates

    - by Rob Farley
    SQL 2012 brings us a bunch of new analytic functions, together with enhancements to the OVER clause. People who have known me over the years will remember that I’m a big fan of the OVER clause and the types of things that it brings us when applied to aggregate functions, as well as the ranking functions that it enables. The OVER clause was introduced in SQL Server 2005, and remained frustratingly unchanged until SQL Server 2012. This post is going to look at a particular aspect of the analytic functions though (not the enhancements to the OVER clause). When I give presentations about the analytic functions around Australia as part of the tour of SQL Saturdays (starting in Brisbane this Thursday), and in Chicago next month, I’ll make sure it’s sufficiently well described. But for this post – I’m going to skip that and assume you get it. The analytic functions introduced in SQL 2012 seem to come in pairs – FIRST_VALUE and LAST_VALUE, LAG and LEAD, CUME_DIST and PERCENT_RANK, PERCENTILE_CONT and PERCENTILE_DISC. Perhaps frustratingly, they take slightly different forms as well. The ones I want to look at now are FIRST_VALUE and LAST_VALUE, and PERCENTILE_CONT and PERCENTILE_DISC. The reason I’m pulling this ones out is that they always produce the same result within their partitions (if you’re applying them to the whole partition). Consider the following query: SELECT     YEAR(OrderDate),     FIRST_VALUE(TotalDue)         OVER (PARTITION BY YEAR(OrderDate)               ORDER BY OrderDate, SalesOrderID               RANGE BETWEEN UNBOUNDED PRECEDING                         AND UNBOUNDED FOLLOWING),     LAST_VALUE(TotalDue)         OVER (PARTITION BY YEAR(OrderDate)               ORDER BY OrderDate, SalesOrderID               RANGE BETWEEN UNBOUNDED PRECEDING                         AND UNBOUNDED FOLLOWING),     PERCENTILE_CONT(0.95)         WITHIN GROUP (ORDER BY TotalDue)         OVER (PARTITION BY YEAR(OrderDate)),     PERCENTILE_DISC(0.95)         WITHIN GROUP (ORDER BY TotalDue)         OVER (PARTITION BY YEAR(OrderDate)) FROM Sales.SalesOrderHeader ; This is designed to get the TotalDue for the first order of the year, the last order of the year, and also the 95% percentile, using both the continuous and discrete methods (‘discrete’ means it picks the closest one from the values available – ‘continuous’ means it will happily use something between, similar to what you would do for a traditional median of four values). I’m sure you can imagine the results – a different value for each field, but within each year, all the rows the same. Notice that I’m not grouping by the year. Nor am I filtering. This query gives us a result for every row in the SalesOrderHeader table – 31465 in this case (using the original AdventureWorks that dates back to the SQL 2005 days). The RANGE BETWEEN bit in FIRST_VALUE and LAST_VALUE is needed to make sure that we’re considering all the rows available. If we don’t specify that, it assumes we only mean “RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW”, which means that LAST_VALUE ends up being the row we’re looking at. At this point you might think about other environments such as Access or Reporting Services, and remember aggregate functions like FIRST. We really should be able to do something like: SELECT     YEAR(OrderDate),     FIRST_VALUE(TotalDue)         OVER (PARTITION BY YEAR(OrderDate)               ORDER BY OrderDate, SalesOrderID               RANGE BETWEEN UNBOUNDED PRECEDING                         AND UNBOUNDED FOLLOWING) FROM Sales.SalesOrderHeader GROUP BY YEAR(OrderDate) ; But you can’t. You get that age-old error: Msg 8120, Level 16, State 1, Line 5 Column 'Sales.SalesOrderHeader.OrderDate' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause. Msg 8120, Level 16, State 1, Line 5 Column 'Sales.SalesOrderHeader.SalesOrderID' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause. Hmm. You see, FIRST_VALUE isn’t an aggregate function. None of these analytic functions are. There are too many things involved for SQL to realise that the values produced might be identical within the group. Furthermore, you can’t even surround it in a MAX. Then you get a different error, telling you that you can’t use windowed functions in the context of an aggregate. And so we end up grouping by doing a DISTINCT. SELECT DISTINCT     YEAR(OrderDate),         FIRST_VALUE(TotalDue)              OVER (PARTITION BY YEAR(OrderDate)                   ORDER BY OrderDate, SalesOrderID                   RANGE BETWEEN UNBOUNDED PRECEDING                             AND UNBOUNDED FOLLOWING),         LAST_VALUE(TotalDue)             OVER (PARTITION BY YEAR(OrderDate)                   ORDER BY OrderDate, SalesOrderID                   RANGE BETWEEN UNBOUNDED PRECEDING                             AND UNBOUNDED FOLLOWING),     PERCENTILE_CONT(0.95)          WITHIN GROUP (ORDER BY TotalDue)         OVER (PARTITION BY YEAR(OrderDate)),     PERCENTILE_DISC(0.95)         WITHIN GROUP (ORDER BY TotalDue)         OVER (PARTITION BY YEAR(OrderDate)) FROM Sales.SalesOrderHeader ; I’m sorry. It’s just the way it goes. Hopefully it’ll change the future, but for now, it’s what you’ll have to do. If we look in the execution plan, we see that it’s incredibly ugly, and actually works out the results of these analytic functions for all 31465 rows, finally performing the distinct operation to convert it into the four rows we get in the results. You might be able to achieve a better plan using things like TOP, or the kind of calculation that I used in http://sqlblog.com/blogs/rob_farley/archive/2011/08/23/t-sql-thoughts-about-the-95th-percentile.aspx (which is how PERCENTILE_CONT works), but it’s definitely convenient to use these functions, and in time, I’m sure we’ll see good improvements in the way that they are implemented. Oh, and this post should be good for fellow SQL Server MVP Nigel Sammy’s T-SQL Tuesday this month.

  • How to Disable Access to the Registry in Windows 7

    - by Mysticgeek
    If you don’t know what your doing in the Registry, you can mess up your computer pretty good. Today we show you how to prevent users from accessing the Registry and making any changes to it. Using Local Group Policy Editor Note: This method uses Group Policy Editor which is not available in Home versions of Windows. First type gpedit.msc into the Search box in the Start menu. When Group Policy Editor opens, navigate to User Configuration \ Administrative Templates then select System. Under Setting in the right panel double-click on Prevent access to registry editing tools. Select the radio button next to Enabled, click OK, then close out of Group Policy Editor. Now if a user tries to access the Registry… They will get the following message advising they cannot access it.   Using Registry Enabler & Disabler 3 If you’re using Home or Starter version of Windows 7, you can use a neat utility called Registry Enabler & Disabler (link below). This app works on XP and Vista as well. There is no installation involved so you can run it from a flash drive, disable the registry, then take the flash drive with you while a the user is on the machine.   Again, if the user tries to access the Registry they will get the following error… Using one of these options will stop users from gaining access to the Registry or running any registry hacks. Of course if you have a shared computer, you may want to set up other users with a Standard Account, as they won’t be able to make changes to the Registry anyway.

  • AdvancedFormatProvider: Making string.format do more

    - by plblum
    When I have an integer that I want to format within the String.Format() and ToString(format) methods, I’m always forgetting the format symbol to use with it. That’s probably because its not very intuitive. Use {0:N0} if you want it with group (thousands) separators. text = String.Format("{0:N0}", 1000); // returns "1,000"   int value1 = 1000; text = value1.ToString("N0"); Use {0:D} or {0:G} if you want it without group separators. text = String.Format("{0:D}", 1000); // returns "1000"   int value2 = 1000; text2 = value2.ToString("D"); The {0:D} is especially confusing because Microsoft gives the token the name “Decimal”. I thought it reasonable to have a new format symbol for String.Format, "I" for integer, and the ability to tell it whether it shows the group separators. Along the same lines, why not expand the format symbols for currency ({0:C}) and percent ({0:P}) to let you omit the currency or percent symbol, omit the group separator, and even to drop the decimal part when the value is equal to the whole number? My solution is an open source project called AdvancedFormatProvider, a group of classes that provide the new format symbols, continue to support the rest of the native symbols and makes it easy to plug in additional format symbols. Please visit https://github.com/plblum/AdvancedFormatProvider to learn about it in detail and explore how its implemented. The rest of this post will explore some of the concepts it takes to expand String.Format() and ToString(format). AdvancedFormatProvider benefits: Supports {0:I} token for integers. It offers the {0:I-,} option to omit the group separator. Supports {0:C} token with several options. {0:C-$} omits the currency symbol. {0:C-,} omits group separators, and {0:C-0} hides the decimal part when the value would show “.00”. For example, 1000.0 becomes “$1000” while 1000.12 becomes “$1000.12”. Supports {0:P} token with several options. {0:P-%} omits the percent symbol. {0:P-,} omits group separators, and {0:P-0} hides the decimal part when the value would show “.00”. For example, 1 becomes “100 %” while 1.1223 becomes “112.23 %”. Provides a plug in framework that lets you create new formatters to handle specific format symbols. You register them globally so you can just pass the AdvancedFormatProvider object into String.Format and ToString(format) without having to figure out which plug ins to add. text = String.Format(AdvancedFormatProvider.Current, "{0:I}", 1000); // returns "1,000" text2 = String.Format(AdvancedFormatProvider.Current, "{0:I-,}", 1000); // returns "1000" text3 = String.Format(AdvancedFormatProvider.Current, "{0:C-$-,}", 1000.0); // returns "1000.00" The IFormatProvider parameter Microsoft has made String.Format() and ToString(format) format expandable. They each take an additional parameter that takes an object that implements System.IFormatProvider. This interface has a single member, the GetFormat() method, which returns an object that knows how to convert the format symbol and value into the desired string. There are already a number of web-based resources to teach you about IFormatProvider and the companion interface ICustomFormatter. I’ll defer to them if you want to dig more into the topic. The only thing I want to point out is what I think are implementation considerations. Why GetFormat() always tests for ICustomFormatter When you see examples of implementing IFormatProviders, the GetFormat() method always tests the parameter against the ICustomFormatter type. Why is that? public object GetFormat(Type formatType) { if (formatType == typeof(ICustomFormatter)) return this; else return null; } The value of formatType is already predetermined by the .net framework. String.Format() uses the StringBuilder.AppendFormat() method to parse the string, extracting the tokens and calling GetFormat() with the ICustomFormatter type. (The .net framework also calls GetFormat() with the types of System.Globalization.NumberFormatInfo and System.Globalization.DateTimeFormatInfo but these are exclusive to how the System.Globalization.CultureInfo class handles its implementation of IFormatProvider.) Your code replaces instead of expands I would have expected the caller to pass in the format string to GetFormat() to allow your code to determine if it handles the request. My vision would be to return null when the format string is not supported. The caller would iterate through IFormatProviders until it finds one that handles the format string. Unfortunatley that is not the case. The reason you write GetFormat() as above is because the caller is expecting an object that handles all formatting cases. You are effectively supposed to write enough code in your formatter to handle your new cases and call .net functions (like String.Format() and ToString(format)) to handle the original cases. Its not hard to support the native functions from within your ICustomFormatter.Format function. Just test the format string to see if it applies to you. If not, call String.Format() with a token using the format passed in. public string Format(string format, object arg, IFormatProvider formatProvider) { if (format.StartsWith("I")) { // handle "I" formatter } else return String.Format(formatProvider, "{0:" + format + "}", arg); } Formatters are only used by explicit request Each time you write a custom formatter (implementer of ICustomFormatter), it is not used unless you explicitly passed an IFormatProvider object that supports your formatter into String.Format() or ToString(). This has several disadvantages: Suppose you have several ICustomFormatters. In order to have all available to String.Format() and ToString(format), you have to merge their code and create an IFormatProvider to return an instance of your new class. You have to remember to utilize the IFormatProvider parameter. Its easy to overlook, especially when you have existing code that calls String.Format() without using it. Some APIs may call String.Format() themselves. If those APIs do not offer an IFormatProvider parameter, your ICustomFormatter will not be available to them. The AdvancedFormatProvider solves the first two of these problems by providing a plug-in architecture.

  • Granular Clipboard Control in Oracle IRM

    - by martin.abrahams
    One of the main leak prevention controls that customers are looking for is clipboard control. After all, there is little point in controlling access to a document if authorised users can simply make unprotected copies by use of the cut and paste mechanism. Oddly, for such a fundamental requirement, many solutions only offer very simplistic clipboard control - and require the customer to make an awkward choice between usability and security. In many cases, clipboard control is simply an ON-OFF option. By turning the clipboard OFF, you disable one of the most valuable edit functions known to man. Try working for any length of time without copying and pasting, and you'll soon appreciate how valuable that function is. Worse, some solutions disable the clipboard completely - not just for the protected document but for all of the various applications you have open at the time. Normal service is only resumed when you close the protected document. In this way, policy enforcement bleeds out of the particular assets you need to protect and interferes with the entire user experience. On the other hand, turning the clipboard ON satisfies a fundamental usability requirement - but also makes it really easy for users to create unprotected copies of sensitive information, maliciously or otherwise. All they need to do is paste into another document. If creating unprotected copies is this simple, you have to question how much you are really gaining by applying protection at all. You may not be allowed to edit, forward, or print the protected asset, but all you need to do is create a copy and work with that instead. And that activity would not be tracked in any way. So, a simple ON-OFF control creates a real tension between usability and security. If you are only using IRM on a small scale, perhaps security can outweigh usability - the business can put up with the restriction if it only applies to a handful of important documents. But try extending protection to large numbers of documents and large user communities, and the restriction rapidly becomes really unwelcome. I am aware of one solution that takes a different tack. Rather than disable the clipboard, pasting is always permitted, but protection is automatically applied to any document that you paste into. At first glance, this sounds great - protection travels with the content. However, at any scale this model may not be so appealing once you've had to deal with support calls from users who have accidentally applied protection to documents that really don't need it - which would be all too easily done. This may help control leakage, but it also pollutes the system with documents that have policies applied with no obvious rhyme or reason, and it can seriously inconvenience the business by making non-sensitive documents difficult to access. And what policy applies if you paste some protected content into an already protected document? Which policy applies? There are no prizes for guessing that Oracle IRM takes a rather different approach. The Oracle IRM Approach Oracle IRM offers a spectrum of clipboard controls between the extremes of ON and OFF, and it leverages the classification-based rights model to give granular control that satisfies both security and usability needs. Firstly, we take it for granted that if you have EDIT rights, of course you can use the clipboard within a given document. Why would we force you to retype a piece of content that you want to move from HERE... to HERE...? If the pasted content remains in the same document, it is equally well protected whether it be at the beginning, middle, or end - or all three. So, the first point is that Oracle IRM always enables the clipboard if you have the right to edit the file. Secondly, whether we enable or disable the clipboard, we only affect the protected document. That is, you can continue to use the clipboard in the usual way for unprotected documents and applications regardless of whether the clipboard is enabled or disabled for the protected document(s). And if you have multiple protected documents open, each may have the clipboard enabled or disabled independently, according to whether you have Edit rights for each. So, even for the simplest cases - the ON-OFF cases - Oracle IRM adds value by containing the effect to the protected documents rather than to the whole desktop environment. Now to the granular options between ON and OFF. Thanks to our classification model, we can define rights that enable pasting between documents in the same classification - ie. between documents that are protected by the same policy. So, if you are working on this month's financial report and you want to pull some data from last month's report, you can simply cut and paste between the two documents. The two documents are classified the same way, subject to the same policy, so the content is equally safe in both documents. However, if you try to paste the same data into an unprotected document or a document in a different classification, you can be prevented. Thus, the control balances legitimate user requirements to allow pasting with legitimate information security concerns to keep data protected. We can take this further. You may have the right to paste between related classifications of document. So, the CFO might want to copy some financial data into a board document, where the two documents are sealed to different classifications. The CFO's rights may well allow this, as it is a reasonable thing for a CFO to want to do. But policy might prevent the CFO from copying the same data into a classification that is accessible to external parties. The above option, to copy between classifications, may be for specific classifications or open-ended. That is, your rights might enable you to go from A to B but not to C, or you might be allowed to paste to any classification subject to your EDIT rights. As for so many features of Oracle IRM, our classification-based rights model makes this type of granular control really easy to manage - you simply define that pasting is permitted between classifications A and B, but omit C. Or you might define that pasting is permitted between all classifications, but not to unprotected locations. The classification model enables millions of documents to be controlled by a few such rules. Finally, you MIGHT have the option to paste anywhere - such that unprotected copies may be created. This is rare, but a legitimate configuration for some users, some use cases, and some classifications - but not something that you have to permit simply because the alternative is too restrictive. As always, these rights are defined in user roles - so different users are subject to different clipboard controls as required in different classifications. So, where most solutions offer just two clipboard options - ON-OFF or ON-but-encrypt-everything-you-touch - Oracle IRM offers real granularity that leverages our classification model. Indeed, I believe it is the lack of a classification model that makes such granularity impractical for other IRM solutions, because the matrix of rules for controlling pasting would be impossible to manage - there are so many documents to consider, and more are being created all the time.

  • WNA Configuration in OAM 11g

    - by P Patra
    Pre-Requisite: Kerberos authentication scheme has to exist. This is usually pre-configured OAM authentication scheme. It should have Authentication Level - "2", Challenge Method - "WNA", Challenge Direct URL - "/oam/server" and Authentication Module- "Kerberos". The default authentication scheme name is "KerberosScheme", this name can be changed. The DNS name has to be resolvable on the OAM Server. The DNS name with referrals to AD have to be resolvable on OAM Server. Ensure nslookup work for the referrals. Pre-Install: AD team to produce keytab file on the AD server by running ktpass command. Provide OAM Hostname to AD Team. Receive from AD team the following: Keypass file produced when running the ktpass command ktpass username ktpass password Copy the keytab file to convenient location in OAM install tree and rename the file if desired. For instance where oam-policy.xml file resides. i.e. /fa_gai2_d/idm/admin/domains/idm-admin/IDMDomain/config/fmwconfig/keytab.kt Configure WNA Authentication on OAM Server: Create config file krb.config and set the environment variable to the path to this file: KRB_CONFIG=/fa_gai2_d/idm/admin/domains/idm-admin/IDMDomain/config/fmwconfig/krb.conf The variable KRB_CONFIG has to be set in the profile for the user that OAM java container(i.e. Wbelogic Server) runs as, so that this setting is available to the OAM server. i.e. "applmgr" user. In the krb.conf file specify: [libdefaults] default_realm= NOA.ABC.COM dns_lookup_realm= true dns_lookup_kdc= true ticket_lifetime= 24h forwardable= yes [realms] NOA.ABC.COM={ kdc=hub21.noa.abc.com:88 admin_server=hub21.noa.abc.com:749 default_domain=NOA.ABC.COM [domain_realm] .abc.com=ABC.COM abc.com=ABC.COM .noa.abc.com=NOA.ABC.COM noa.abc.com=NOA.ABC.COM Where hub21.noa.abc.com is load balanced DNS VIP name for AD Server and NOA.ABC.COM is the name of the domain. Create authentication policy to WNA protect the resource( i.e. EBSR12) and choose the "KerberosScheme" as authentication scheme. Login to OAM Console => Policy Configuration Tab => Browse Tab => Shared Components => Application Domains => IAM Suite => Authentication Policies => Create Name: ABC WNA Auth Policy Authentication Scheme: KerberosScheme Failure URL: http://hcm.noa.abc.com/cgi-bin/welcome Edit System Configuration for Kerberos System Configuration Tab => Access Manager Settings => expand Authentication Modules => expand Kerberos Authentication Module => double click on Kerberos Edit "Key Tab File" textbox - put in /fa_gai2_d/idm/admin/domains/idm-admin/IDMDomain/config/fmwconfig/keytab.kt Edit "Principal" textbox - put in HTTP/[email protected] Edit "KRB Config File" textbox - put in /fa-gai2_d/idm/admin/domains/idm-admin/IDMDomain/config/fmwconfig/krb.conf Cilck "Apply" In the script setting environment for the WLS server where OAM is deployed set the variable: KRB_CONFIG=/fa_gai2_d/idm/admin/domains/idm-admin/IDMDomain/config/fmwconfig/krb.conf Re-start OAM server and OAM Server Container( Weblogic Server)

    The organizers of SQL Saturday #61 in DC (actually Reston, VA) created an Advanced DBA/Dev track for their event, which I think is cool. Both of the presentations I'll be doing there on Saturday are in that track. (In fact, they're the first two sessions of the day.) The first, Automate Policy-Based Management using PowerShell will walk through the basics of Policy-Based Management, and then show you how to build PowerShell scripts to create and evaluate your policies. The second, Gather SQL Server...(read more)

  • Process Rules!

    - by Ajay Khanna
    One of the key components of a process is “Business Rule”. Business rule takes many forms inside your process definition and in a way is a manifestation of your company’s business policy. Business rules inside the process are used for policy enforcement, governance, decision management, operations efficiency etc. Following are some basic types of rules that can be a part of your process. 1. Process conditions:  These are defined as the process gateways that determine a path process will take depending on the process parameters. For Example, if discount >10% go to approval path : if discount < 10% auto-approve order. 2. Data rules: These business rules are defined as facts in decision table or knowledge base. The process captures all required parameters and submits those to RETE based rules engine. Rules engine processes the data and returns the result back. For example, rules determining your insurance eligibility. 3. Event rules: Here the system is monitoring the various events and events patterns that are emerging inside the process or external to the process. You can define actions or alerts to be triggered when a certain pattern of events emerges over a specified time period. Such types of rules need Complex Event Processing and are used in applications like Credit Card Fraud detection or Utility Demand Response. 4. User Interface Rules: In order to add dynamic behavior to UI or to keep users from making mistakes and enforcing policy, another mechanism available is UI rules. They are evaluated as the end user is filling out the web forms. These may include enabling and disabling of UI as per business policy. An example could be, if the age of a user is less than 13 years, disable credit card field and enable parental approval required checkbox. Your process may include many of such rule types. Oracle OpenWorld provides a unique opportunity to listen to Oracle Business Process Management Experts and Customers.  We will discuss business rules during various sessions in Oracle OpenWorld.

  • Strange Flash AS3 xml Socket behavior

    - by Rnd_d
    I have a problem which I can't understand. To understand it I wrote a socket client on AS3 and a server on python/twisted, you can see the code of both applications below. Let's launch two clients at the same time, arrange them so that you can see both windows and press connection button in both windows. Then press and hold any button. What I'm expecting: Client with pressed button sends a message "some data" to the server, then the server sends this message to all the clients(including the original sender) . Then each client moves right the button 'connectButton' and prints a message to the log with time in the following format: "min:secs:milliseconds". What is going wrong: The motion is smooth in the client that sends the message, but in all other clients the motion is jerky. This happens because messages to those clients arrive later than to the original sending client. And if we have three clients (let's name them A,B,C) and we send a message from A, the sending time log of B and C will be the same. Why other clients recieve this messages later than the original sender? By the way, on ubuntu 10.04/chrome all the motion is smooth. Two clients are launched in separated chromes. windows screenshot Can't post linux screenshot, need more than 10 reputation to post more hyperlinks. Listing of log, four clients simultaneously: [16:29:33.280858] 62.140.224.1 >> some data [16:29:33.280912] 87.249.9.98 << some data [16:29:33.280970] 87.249.9.98 << some data [16:29:33.281025] 87.249.9.98 << some data [16:29:33.281079] 62.140.224.1 << some data [16:29:33.323267] 62.140.224.1 >> some data [16:29:33.323326] 87.249.9.98 << some data [16:29:33.323386] 87.249.9.98 << some data [16:29:33.323440] 87.249.9.98 << some data [16:29:33.323493] 62.140.224.1 << some data [16:29:34.123435] 62.140.224.1 >> some data [16:29:34.123525] 87.249.9.98 << some data [16:29:34.123593] 87.249.9.98 << some data [16:29:34.123648] 87.249.9.98 << some data [16:29:34.123702] 62.140.224.1 << some data AS3 client code package { import adobe.utils.CustomActions; import flash.display.Sprite; import flash.events.DataEvent; import flash.events.Event; import flash.events.IOErrorEvent; import flash.events.KeyboardEvent; import flash.events.MouseEvent; import flash.events.SecurityErrorEvent; import flash.net.XMLSocket; import flash.system.Security; import flash.text.TextField; public class Main extends Sprite { private var socket :XMLSocket; private var textField :TextField = new TextField; private var connectButton :TextField = new TextField; public function Main():void { if (stage) init(); else addEventListener(Event.ADDED_TO_STAGE, init); } private function init(event:Event = null):void { socket = new XMLSocket(); socket.addEventListener(Event.CONNECT, connectHandler); socket.addEventListener(DataEvent.DATA, dataHandler); stage.addEventListener(KeyboardEvent.KEY_DOWN, keyDownHandler); addChild(textField); textField.y = 50; textField.width = 780; textField.height = 500; textField.border = true; connectButton.selectable = false; connectButton.border = true; connectButton.addEventListener(MouseEvent.MOUSE_DOWN, connectMouseDownHandler); connectButton.width = 105; connectButton.height = 20; connectButton.text = "click here to connect"; addChild(connectButton); } private function connectHandler(event:Event):void { textField.appendText("Connect\n"); textField.appendText("Press and hold any key\n"); } private function dataHandler(event:DataEvent):void { var now:Date = new Date(); textField.appendText(event.data + " time = " + now.getMinutes() + ":" + now.getSeconds() + ":" + now.getMilliseconds() + "\n"); connectButton.x += 2; } private function keyDownHandler(event:KeyboardEvent):void { socket.send("some data"); } private function connectMouseDownHandler(event:MouseEvent):void { var connectAddress:String = "ep1c.org"; var connectPort:Number = 13250; Security.loadPolicyFile("xmlsocket://" + connectAddress + ":" + String(connectPort)); socket.connect(connectAddress, connectPort); } } } Python server code from twisted.internet import reactor from twisted.internet.protocol import ServerFactory from twisted.protocols.basic import LineOnlyReceiver import datetime class EchoProtocol(LineOnlyReceiver): ##### name = "" id = 0 delimiter = chr(0) ##### def getName(self): return self.transport.getPeer().host def connectionMade(self): self.id = self.factory.getNextId() print "New connection from %s - id:%s" % (self.getName(), self.id) self.factory.clientProtocols[self.id] = self def connectionLost(self, reason): print "Lost connection from "+ self.getName() del self.factory.clientProtocols[self.id] self.factory.sendMessageToAllClients(self.getName() + " has disconnected.") def lineReceived(self, line): print "[%s] %s >> %s" % (datetime.datetime.now().time(), self, line) if line=="<policy-file-request/>": data = """<?xml version="1.0"?> <!DOCTYPE cross-domain-policy SYSTEM "http://www.adobe.com/xml/dtds/cross-domain-policy.dtd"> <!-- Policy file for xmlsocket://ep1c.org --> <cross-domain-policy> <allow-access-from domain="*" to-ports="%s" /> </cross-domain-policy>""" % PORT self.send(data) else: self.factory.sendMessageToAllClients( line ) def send(self, line): print "[%s] %s << %s" % (datetime.datetime.now().time(), self, line) if line: self.transport.write( str(line) + chr(0)) else: print "Nothing to send" def __str__(self): return self.getName() class ChatProtocolFactory(ServerFactory): protocol = EchoProtocol def __init__(self): self.clientProtocols = {} self.nextId = 0 def getNextId(self): id = self.nextId self.nextId += 1 return id def sendMessageToAllClients(self, msg): for client in self.clientProtocols: self.clientProtocols[client].send(msg) def sendMessageToClient(self, id, msg): self.clientProtocols[id].send(msg) PORT = 13250 print "Starting Server" factory = ChatProtocolFactory() reactor.listenTCP(PORT, factory) reactor.run()

  • Check SQL Server Virtual Log Files Using PowerShell

    In a previous tip on Monitor Your SQL Server Virtual Log Files with Policy Based Management, we have seen how we can use Policy Based Management to monitor the number of virtual log files (VLFs) in our SQL Server databases. However, even with that most of the solutions I see online involve the creation of temporary tables and/or a combination of using cursors to get the total number of VLFs in a transaction log file. Is there a much easier solution?

  • Looking for definitive answer to accessing a network drive/NAS/SMB drive via Windows 7 HOME and Windows 7 Professional. Is it possible and how?

    - by Rob
    I want to be able to access my Lacie 2Big network drive in Windows 7 Explorer. I have a machine with Windows 7 Home and one with Windows 7 Professional. Neither Windows 7, home or pro, can access the drive. The Windows 7 Home machine displays the drive in its Explorer, with the capacity, but on clicking the icon, I get another window, blank with the busy pointer which does not eventually stop. The drive is working perfectly. How do I know this? Because I can access it with no problems on my Apple Mac, Windows XP home and Ubuntu machines on the same network as the Windows 7 machines. Except for the Windows XP home machine that required Lacie ethernet agent program, the Mac and the Ubuntu machines needed no setup, the drive appeared like any other drive. So my 2 questions: Is it possible to access a network share drive, e.g. a NAS like Lacie 2big in Windows 7 Home Premium and Windows 7 Professional. If so how? I read on Microsoft's own forums and elsewhere that network sharing drives, e.g. via SambaSMB is NOT possible on Windows 7 Home. Is this true? http://social.technet.microsoft.com/Forums/en-US/w7itprovirt/thread/e08c3500-a722-4b44-b644-64f94f63c8e5/ This question is a more comprehensive re-write of my earlier question: Windows 7 / TCP/IP network share guide - looking for to resolve failure to mount lacie network drive but works on XP,Linux,Mac. ...where I haven't received a solving answer, and I have tried to find a solution myself. Lacie themselves haven't offered a definitive solving answer either, but I suspect it's not just their drives but SMB/network share/NAS in general... This is utterly pathetic that Windows 7 home cannot access something as simple as a network drive, especially given that Windows XP home can. My research so far: Apparently it is possible on Windows 7 Professional, via the Local Security Policy, only on Windows 7 Professional, not Windows 7 Home: http://www.sevenforums.com/tutorials/7357-local-security-policy-editor-open.html http://answers.microsoft.com/en-us/windows/forum/windows_7-security/accessing-local-security-policy-in-windows-7-home/0c8300d0-1d23-4de0-9b37-935c01a7d17a http://social.technet.microsoft.com/Forums/en-US/w7itprosecurity/thread/14fc5037-3386-4973-b5d8-2167272ff5ad/ http://www.tomshardware.com/forum/75-63-windows-samba-issue Another solution offered is editing the registry, doesn't look promising to me, fiddly and not guaranteed, hard to produce a complete solution I think, given that everyone's registry can vary.

  • seaudit report detail

    - by user1014130
    I've just started using selinux in the last 6 months and am getting to grips with it. However, using sealert on a new CENTOS 6 server, Im not getting the level of detail I was with CENTOS 5. To illustrate: Running sealert -a /var/log/audit/audit.log On CENTOS 5 I get: Summary: SELinux is preventing postdrop (postfix_postdrop_t) "getattr" to /var/log/httpd/error_log (httpd_log_t). Detailed Description: SELinux denied access requested by postdrop. It is not expected that this access is required by postdrop and this access may signal an intrusion attempt. It is also possible that the specific version or configuration of the application is causing it to require additional access. Allowing Access: Sometimes labeling problems can cause SELinux denials. You could try to restore the default system file context for /var/log/httpd/error_log, restorecon -v '/var/log/httpd/error_log' If this does not work, there is currently no automatic way to allow this access. Instead, you can generate a local policy module to allow this access - see FAQ (http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Or you can disable SELinux protection altogether. Disabling SELinux protection is not recommended. Please file a bug report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi) against this package.

  • Dynamic Grouping and Columns

    - by Tim Dexter
    Some good collaboration between myself and Kan Nishida (Oracle BIP Consulting) over at bipconsulting on a question that came in yesterday to an internal mailing list. Is there a way to allow columns to be place into a template dynamically? This would be similar to the Answers Column selector. A customer has said Crystal can do this and I am trying to see how BI Pub can do the same. Example: Report has Regions as a dimension in a table, they want the user to select a parameter that will insert either Units or Dollars without having to create multiple templates. Now whether Crystal can actually do it or not is another question, can Publisher? Yes we can! Kan took the first stab. His approach, was to allow to swap out columns in a table in the report. Some quick steps: 1. Create a parameter from BIP server UI 2. Declare the parameter in RTF template You can check this post to see how you can declare the parameter from the server. http://bipconsulting.blogspot.com/2010/02/how-to-pass-user-input-values-to-report.html 3. Use the parameter value to condition if a particular column needs to be displayed or not. You can use <?if@column:.....?> syntax for Column level IF condition. The if@column is covered in user documentation. This would allow a developer to create a report with the parameter or multiple parameters to allow the user to pick a column to be included in the report. I took a slightly different tack, with the mention of the column selector in the Answers report I took that to mean that the user wanted to select more of a dimensional column and then have the report recalculate all its totals and subtotals based on that selected column. This is a little bit more involved and involves some smart XSL and XPATH expressions, but still very doable. The user can select a column as a parameter, that is passed to the template rather than the query. The parameter value that is actually passed is the element name that you want to regroup the data by. Inside the template we then reference that parameter value in our for-each-group loop. That's where we need the trixy XSL/XPATH code to get the regrouping to happen. At this juncture, I need to hat tip to Klaus, for his article on dynamic sorting that he wrote back in 2006. I basically took his sorting code and applied it to the for-each loop. You can follow both of Kan's first two steps above i.e. Create a parameter from BIP server UI - this just needs to be based on a 'list' type list of value with name/value pairs e.g. Department/DEPARTMENT_NAME, Job/JOB_TITLE, etc. The user picks the 'friendly' value and the server passes the element name to the template. Declare the parameter in RTF template - been here before lots of times right? <?param@begin:group1;'"DEPARTMENT_NAME"'?> I have used a default value so that I can test the funtionality inside the template builder (notice the single and double quotes.) Next step is to use the template builder to build a re-grouped report layout. It does not matter if its hard coded right now; we will add in the dynamic piece next. Once you have a functioning template that is re-grouping correctly. Open up the for-each-group field and modify it to use the parameter: <?for-each-group:ROW;./*[name(.) = $group1]?> 'group1' is my grouping parameter, declared above. We need the XPATH expression to find the column in the XML structure we want to group that matches the one passed by the parameter. Its essentially looking through the data tree for a match. We can show the actual grouping value in the report output with a similar XPATH expression <?./*[name(.) = $group1]?> In my example, I took things a little further so that I could have a dynamic label for the parameter value. For instance if I am using MANAGER as the parameter I want to show: Manager: Tim Dexter My XML elements are readable e.g. DEPARTMENT_NAME. Its a simple case of replacing the underscore with a space and then 'initcapping' the result: <?xdoxslt:init_cap(translate($group1,'_',' '))?> With this in place, the user can now select a grouping column in the BIP report viewer and the layout will re-group the data and any calculations based on that column. I built a group above report but you could equally build the group left version to truly mimic the Answers column selector. If you are interested you can get an example report, sample data and layout template here. Of course, you can combine Klaus' dynamic sorting, Kan's conditional column approach and this dynamic grouping to build a real kick ass report for users that will keep them happy for hours..

  • Look Inside WebLogic Server Embedded LDAP with an LDAP Explorer

    - by james.bayer
    Today a question came up on our internal WebLogic Server mailing lists about an issue deleting a Group from WebLogic Server.  The group had a special character in the name. The WLS console refused to delete the group with the message a java.net.MalformedURLException and another message saying “Errors must be corrected before proceeding.” as shown below. The group aa:bb is the one with the issue.  Click to enlarge. WebLogic Server includes an embedded LDAP server that can be used for managing users and groups for “reasonably small environments (10,000 or fewer users)”.  For organizations scaling larger or using more high-end features, I recommend looking at one of Oracle’s very popular enterprise directory services products like Oracle Internet Directory or Oracle Directory Server Enterprise Edition.  You can configure multiple authenicators in WebLogic Server so that you can use multiple directories at the same time. I am not sure WebLogic Server supports special characters in group names for the Embedded LDAP server, but in this case both the console and WLST reported the same issue deleting the group with the special character in the name.  Here’s the WLST output: wls:/hotspot_domain/serverConfig/SecurityConfiguration/hotspot_domain/Realms/myrealm/AuthenticationProviders/DefaultAuthenticator> cmo.removeGroup('aa:bb') Traceback (innermost last): File "<console>", line 1, in ?

Follow the instructions here, being sure to change the authentication credentials to the Embedded LDAP server to some value you know, as by default they are some unknown value.  You’ll need to reboot the WebLogic Server Admin Server after making this change. Now configure JXplorer to connect as described in the documentation.  I’ve circled the important inputs.  In this example, my domain name is “hotspot_domain” which listens on the localhost listen address and port 7001.  The cn=Admin user name is a constant identifier for the Administrator of the embedded LDAP and that does not change, but you need to know what it is so you can enter it into the tool you use. Once you connect successfully, you can explore the entries and in this case delete the group that is no longer desired.

  • Talking JavaOne with Rock Star Martijn Verburg

    - by Janice J. Heiss
    JavaOne Rock Stars, conceived in 2005, are the top-rated speakers at each JavaOne Conference. They are awarded by their peers, who, through conference surveys, recognize them for their outstanding sessions and speaking ability. Over the years many of the world’s leading Java developers have been so recognized. Martijn Verburg has, in recent years, established himself as an important mover and shaker in the Java community. His “Diabolical Developer” session at the JavaOne 2011 Conference got people’s attention by identifying some of the worst practices Java developers are prone to engage in. Among other things, he is co-leader and organizer of the thriving London Java User Group (JUG) which has more than 2,500 members, co-represents the London JUG on the Executive Committee of the Java Community Process, and leads the global effort for the Java User Group “Adopt a JSR” and “Adopt OpenJDK” programs. Career highlights include overhauling technology stacks and SDLC practices at Mizuho International, mentoring Oracle on technical community management, and running off shore development teams for AIG. He is currently CTO at jClarity, a start-up focusing on automating optimization for Java/JVM related technologies, and Product Advisor at ZeroTurnaround. He co-authored, with Ben Evans, "The Well-Grounded Java Developer" published by Manning and, as a leading authority on technical team optimization, he is in high demand at major software conferences.Verburg is participating in five sessions, a busy man indeed. Here they are: CON6152 - Modern Software Development Antipatterns (with Ben Evans) UGF10434 - JCP and OpenJDK: Using the JUGs’ “Adopt” Programs in Your Group (with Csaba Toth) BOF4047 - OpenJDK Building and Testing: Case Study—Java User Group OpenJDK Bugathon (with Ben Evans and Cecilia Borg) BOF6283 - 101 Ways to Improve Java: Why Developer Participation Matters (with Bruno Souza and Heather Vancura-Chilson) HOL6500 - Finding and Solving Java Deadlocks (with Heinz Kabutz, Kirk Pepperdine, Ellen Kraffmiller and Henri Tremblay) When I asked Verburg about the biggest mistakes Java developers tend to make, he listed three: A lack of communication -- Software development is far more a social activity than a technical one; most projects fail because of communication issues and social dynamics, not because of a bad technical decision. Sadly, many developers never learn this lesson. No source control -- Developers simply storing code in local filesystems and emailing code in order to integrate Design-driven Design -- The need for some developers to cram every design pattern from the Gang of Four (GoF) book into their source code All of which raises the question: If these practices are so bad, why do developers engage in them? “I've seen a wide gamut of reasons,” said Verburg, who lists them as: * They were never taught at high school/university that their bad habits were harmful.* They weren't mentored in their first professional roles.* They've lost passion for their craft.* They're being deliberately malicious!* They think software development is a technical activity and not a social one.* They think that they'll be able to tidy it up later.A couple of key confusions and misconceptions beset Java developers, according to Verburg. “With Java and the JVM in particular I've seen a couple of trends,” he remarked. “One is that developers think that the JVM is a magic box that will clean up their memory, make their code run fast, as well as make them cups of coffee. The JVM does help in a lot of cases, but bad code can and will still lead to terrible results! The other trend is to try and force Java (the language) to do something it's not very good at, such as rapid web development. So you get a proliferation of overly complex frameworks, libraries and techniques trying to get around the fact that Java is a monolithic, statically typed, compiled, OO environment. It's not a Golden Hammer!”I asked him about the keys to running a good Java User Group. “You need to have a ‘Why,’” he observed. “Many user groups know what they do (typically, events) and how they do it (the logistics), but what really drives users to join your group and to stay is to give them a purpose. For example, within the LJC we constantly talk about the ‘Why,’ which in our case is several whys:* Re-ignite the passion that developers have for their craft* Raise the bar of Java developers in London* We want developers to have a voice in deciding the future of Java* We want to inspire the next generation of tech leaders* To bring the disparate tech groups in London together* So we could learn from each other* We believe that the Java ecosystem forms a cornerstone of our society today -- we want to protect that for the futureLooking ahead to Java 8 Verburg expressed excitement about Lambdas. “I cannot wait for Lambdas,” he enthused. “Brian Goetz and his group are doing a great job, especially given some of the backwards compatibility that they have to maintain. It's going to remove a lot of boiler plate and yet maintain readability, plus enable massive scaling.”Check out Martijn Verburg at JavaOne if you get a chance, and, stay tuned for a longer interview yours truly did with Martijn to be publish on otn/java some time after JavaOne.
