• Deleted vmware ESXi snapshot file - any way to recover?

  - by Mark Allison

  Hi there, I wanted to make some changes to a file server VM today on ESXi 4. The machine is a Debian Lenny guest with two virtual disks - one is 8GB and the other is 500Gb (data). In order to protect the machine from unwanted changes, I made a snapshot of the machine. I went ahead and made my changes and it didn't work out well. So, I powered off the VM and went into snapshot manager and reverted to snapshot. However I reverted to an older snapshot and not the one I just made by mistake. I then (idiotically) deleted the snapshot I just made in snapshot manager. This has resulted in me losing about one year's worth of data. Is there any way to recover this deleted snapshot file? I'm using vmware esxi 4. When I browse the VMWare repository I can see various vmdk files - is it possible the data I need is still there? What should I look for? Thanks, Mark.

• How does Windows 7 DNS client work?

  - by Mark Allison

  I am using a local DHCP and DNS server on my home network on a linux machine. It is running CentOS 6.3 with dnsmasq 2.48. It's all working fine except for local DNS lookups for Windows machines only. I have a mix of Ubuntu, CentOS and Windows machines on the network, some virtual, some physical. I have a machine called boron and the domain is called localdomain If I ping boron from any linux machine, I get [root@lithium lists]# ping -c3 boron PING boron.localdomain (10.0.0.5) 56(84) bytes of data. 64 bytes from boron.localdomain (10.0.0.5): icmp_seq=1 ttl=64 time=0.740 ms 64 bytes from boron.localdomain (10.0.0.5): icmp_seq=2 ttl=64 time=0.478 ms 64 bytes from boron.localdomain (10.0.0.5): icmp_seq=3 ttl=64 time=0.458 ms --- boron.localdomain ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 2000ms rtt min/avg/max/mdev = 0.458/0.558/0.740/0.131 ms If I do it from my Windows 7 machine, I get: Ping request could not find host boron. Please check the name and try again. If I try ping boron.localdomain I get: Pinging boron.localdomain [67.215.65.132] with 32 bytes of data: Reply from 67.215.65.132: bytes=32 time=16ms TTL=57 Reply from 67.215.65.132: bytes=32 time=188ms TTL=57 Reply from 67.215.65.132: bytes=32 time=15ms TTL=57 Reply from 67.215.65.132: bytes=32 time=14ms TTL=57 Ping statistics for 67.215.65.132: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 14ms, Maximum = 188ms, Average = 58ms which is clearly wrong. Why is it going out to the internet? Why can't my windows machine resolve the boron hostname to a FQDN? My Windows machines and linux machines get their network config from DHCP. UPDATE If I do ipconfig /all in Windows, it looks as I would expect: Windows IP Configuration Host Name . . . . . . . . . . . . : lanthanum Primary Dns Suffix . . . . . . . : Node Type . . . . . . . . . . . . : Hybrid IP Routing Enabled. . . . . . . . : No WINS Proxy Enabled. . . . . . . . : No DNS Suffix Search List. . . . . . : .localdomain Ethernet adapter Local Area Connection: Connection-specific DNS Suffix . : .localdomain Description . . . . . . . . . . . : Realtek PCIe GBE Family Controller Physical Address. . . . . . . . . : 50-E5-49-38-FC-A2 DHCP Enabled. . . . . . . . . . . : Yes Autoconfiguration Enabled . . . . : Yes IPv4 Address. . . . . . . . . . . : 10.0.0.57(Preferred) Subnet Mask . . . . . . . . . . . : 255.255.255.0 Lease Obtained. . . . . . . . . . : 23 August 2012 13:58:45 Lease Expires . . . . . . . . . . : 24 August 2012 07:58:48 Default Gateway . . . . . . . . . : 10.0.0.6 DHCP Server . . . . . . . . . . . : 10.0.0.6 DNS Servers . . . . . . . . . . . : 10.0.0.6 208.67.222.222 208.67.220.220 NetBIOS over Tcpip. . . . . . . . : Enabled When I do an nslookup I get: Server: carbon.localdomain Address: 10.0.0.6 *** carbon.localdomain can't find boron: Unspecified error However if I do ifconfig -a in Linux I get: [root@nitrogen ~]# ifconfig -a eth0 Link encap:Ethernet HWaddr 00:0C:29:AF:EC:2A inet addr:10.0.0.7 Bcast:10.0.0.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:187687 errors:0 dropped:0 overruns:0 frame:0 TX packets:5857 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:23910700 (22.8 MiB) TX bytes:712964 (696.2 KiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:329894 errors:0 dropped:0 overruns:0 frame:0 TX packets:329894 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:67153143 (64.0 MiB) TX bytes:67153143 (64.0 MiB) and nslookup: [root@nitrogen ~]# nslookup boron Server: 10.0.0.6 Address: 10.0.0.6#53 Name: boron Address: 10.0.0.5 Both machines are on the same network using the same DHCP server.

This is what happens when I ping and nslookup from Windows to a Windows 2008 Server: C:\Users\mark>nslookup magnesium Server: carbon.localdomain Address: 10.0.0.6 Name: magnesium.localdomain Address: 10.0.0.12 C:\Users\mark>ping magnesium Pinging magnesium.localdomain [67.215.65.132] with 32 bytes of data: Reply from 67.215.65.132: bytes=32 time=267ms TTL=57 Reply from 67.215.65.132: bytes=32 time=162ms TTL=57 Reply from 67.215.65.132: bytes=32 time=510ms TTL=57 Reply from 67.215.65.132: bytes=32 time=146ms TTL=57 Ping statistics for 67.215.65.132: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 146ms, Maximum = 510ms, Average = 271ms And from Linux: [root@beryllium ~]# ping -c4 magnesium PING magnesium.localdomain (10.0.0.12) 56(84) bytes of data. 64 bytes from magnesium.localdomain (10.0.0.12): icmp_seq=1 ttl=128 time=0.176 ms 64 bytes from magnesium.localdomain (10.0.0.12): icmp_seq=2 ttl=128 time=0.634 ms 64 bytes from magnesium.localdomain (10.0.0.12): icmp_seq=3 ttl=128 time=0.685 ms 64 bytes from magnesium.localdomain (10.0.0.12): icmp_seq=4 ttl=128 time=0.263 ms --- magnesium.localdomain ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3002ms rtt min/avg/max/mdev = 0.176/0.439/0.685/0.223 ms [root@beryllium ~]# nslookup magnesium Server: 10.0.0.6 Address: 10.0.0.6#53 Name: magnesium.localdomain Address: 10.0.0.12 UPDATE 3 I stopped the Windows DNS client on my Windows 7 machine with net stop dnscache and it is now working fine. It would be nice to get DNS working with the DNS client on, but I might be OK without it, what do you think?

• How do I secure Sql Server 2008 R2

  - by Mark Tait

  I have both a dedicated and a VPS (from Fasthosts) virtual server - the web sites/applications I run on these, access Sql Server stored on the same web server. Until now, I have logged onto Sql Server on both the deidicated and VPS server, from Sql Server Management Studio - until I noticed in my server application logs, multiple attempts to logon to Sql Server using the 'sa' username, but failed password. So someone/bot is trying hard (repeatedly every couple of hours, for approx 20 attempts during each instance) to log on... so obviously I have to lock down access to Sql Sever remotely. What I have done is gone into Configuration Manager, and in Sql Server Network Configuration - Protocols for Sql2008 and also in Sql Native Client 10.0 Configuration - Client Protocols - I have diabled Named Pipes, TCP/IP (and VIA by default). I have left Shared Memory enabled. I also disabled in Sql Server Services, the Sql Server Browser. Now the only way I can manage the databases on these servers, is by logging on to them via Remote Desktop. Can anyone confirm if this is the correct way of stopping anyone maliciously logging on to Sql Server? (I'm not a DBA or security expert - and there are hundreds of articles advising all different ways - but I was hoping for the experts here to confirm, or otherwise, if what I've done is correct) Thank you, Mark

• Hostname vs webpage domain.

  - by Mark

  Hi All, Im just starting to look at deploying a webpage and get into the joy of DNS etc. And im wondering how you set up multiple web-servers all with thier own hostnames/public IP addresses, and yet have them serve up a webpage from one domain. For example, lets say you have a website example.com, and an A record in DNS that points at it's IP address of 1.2.3.4 . You want to have two servers, prod1 and prod2 with some kind of load balancer in front of them for fail over reasons. The way I see it you would want to have the hostnames of these servers as prod1.example.com and prod2.example.com and perhaps loadb.example.com. How would you set up the DNS so this would all work. ie you could ssh to any of the server domains, prod1.example.com, prod2.example.com or loadb.example.com and also just use the www.example.com url to go to the website. And would all these server names be resolvable from the public internet and is that safe? This would be a linux environment, for arguments sake ubuntu, a django framework dynamic website, running in apache 2.2 Cheers Mark

• Top Down RPG Movement w/ Correction?

  - by Corey Ogburn

  I would hope that we have all played Zelda: A Link to the Past, please correct me if I'm wrong, but I want to emulate that kind of 2D, top-down character movement with a touch of correction. It has been done in other games, but I feel this reference would be the easiest to relate to. More specifically the kind of movement and correction I'm talking about is: Floating movement not restricted to tile based movement like Pokemon and other games where one tap of the movement pad moves you one square in that cardinal direction. This floating movement should be able to achieve diagonal motion. If you're walking West and you come to a wall that is diagonal in a North East/South West fashion, you are corrected into a South West movement even if you continue holding left (West) on the controller. This should work for both diagonals correcting in both directions. If you're a few pixels off from walking squarely into a door or hallway, you are corrected into walking through the hall or down the hallway, i.e. bumping into the corner causes you to be pushed into the hall/door. I've hunted for efficient ways to achieve this and have had no luck. To be clear I'm talking about the human character's movement, not an NPC's movement. Are their resources available on this kind of movement? Equations or algorithms explained on a wiki or something? I'm using the XNA Framework, is there anything in it to help with this?

• Podcast Show Notes: By Any Other Name: Governance and Architecture

  - by Bob Rhubart

  The OTN ArchBeat Podcast returns from a brief summer hiatus with a three-part conversation about IT architecture and governance. My guests for this conversation are Eric Stephens , an Oracle Enterprise architect and a frequent guest on this program. Joining Eric on the panel is Tim Hall , Senior Director of product management for the Oracle Enterprise Repository, Oracle Service Registry, and Oracle Application Integration Architecture. Tim made his first appearance on ArchBeat as panelist on the recent program featuring Thomas Erl. The Conversation Listen to Part 1:Why it's important to revive the dormant conversation about IT governance. Listen to Part 2 (Sept 19): Balancing functional, technical, operational requirements to meet the challenge of defining appropriate governance "guardrails." Listen to Part 3 (Sept 26): Bringing IT architecture out of the ivory tower to make governance a less intimidating, more collaborative process. Additional Resources Leveraging Governance to Sustain Enterprise Architecture Efforts, an Oracle white paper by Eric Stephens. SOA, Cloud, and Service Technologies, a transcript of an ArchBeat interview with Thomas Erl, Tim Hall, and Demed L'Her, in which Tim says the following about governance: "For a long time people have argued that SOA governance is sort of an awkward name, no one wanted to be audited. There's 50% of the world that think, yes, we're going to have to tops down initiative to address this and there's 50% of the world that says that it feels like a heavy weight process that I want no part of. So what I think we should do is change the name…"

• MSDN Live 2010 &ndash; Delivered : 24 sessions (4 x 6) on Visual Studio and Team Foundation Server

  - by terje

  We (Mikael Nitell and me) got a whole track on the Norwegian MSDN Live tour this year.  We did these as a pair, and covered 4 cities over 4 days, 6 sessions per day, taking 8 hours to come through it.  The Islandic volcano made the travels a bit rough, but we managed 6 flights out of 8. The first one had to go by van instead, 7-8 hour drive each way together with other MSDN Live presenters – a memorable tour! Oslo was the absolute top point.  We had to change hall to a bigger one. People were crowding, and even the big hall was packed!  The presentations were mostly based on demos, but we had a few slides as well.  They have been uploaded to my SkyDrive.  Info to aliens – some of the text may be Norwegian. The sessions were as follows: Overview of news in Visual Studio and Team Foundation server 2010 Ensuring Quality with VS/TFS 2010 Releasing products with VS/TFS 2010 No More No Repro with VS/TFS 2010 Performance Testing and Parallel Programming with VS/TFS 2010 Migrating to VS/TFS 2010 Tips, tricks, news and some best practices with VS/TFS 2010   In the coming days, I will post up examples from the demos too, with explanations of how they are intended to work. These entries will also contain stuff we had to remove from the actual presentations due to the time constraints. We managed to create recordings of two of the sessions, which will be uploaded to Channel 9 by Microsoft, afaik.   I will update this blog with information about exact locations when that is done. Also note we’re (read:Osiris Data AS) running both Upgrade and Deep Dive courses  on VS/TFS 2010 now in May.  Please look here for more info. If you want to be informed, follow me on Twitter.  All blog entries will be announced on twitter.

• Oracle OpenWorld Highlights

  - by Doug Reid

  We are in the final days of Oracle OpenWorld 2012 and the data integration team have been hard at work giving sessions, meeting customers, demonstrating product and conducting hands-on labs.    It has been a great conference, but the best part is meeting our customers and learning about all the great implementations of our products.  Wednesday was the last day that the exhibition hall was open and attendees were getting in their final opportunities to see our products and meet with the product management team.   Two hours before the close of the hall, people lined up to learn about GoldenGate 11gR2, Monitor, Adapters, Veridata, and all the different use cases.    Here's a picture of Sjaak Vossepoel, who is our DIS Sales Consulting Manager for EMEA speaking to a potential customer on the options of using Oracle GoldenGate for heterogenous data replication.  Over the last two days, the GoldenGate team ran two labs; Introduction to Oracle GoldenGate Veridata and Deep Dive into Oracle GoldenGate.   Both of the labs were completely booked out and unfortunately we had to turn away people.   BUT,  all of our labs were recorded recently so if you were not able to get into the lab or did not have enough time to complete your labs, visit youtube.com/oraclegoldengate to see a  complete recording of the labs we used at OpenWorld plus more.  Here are a couple pictures from the Deep Dive into Oracle GoldenGate lead by Chis Lawless from the Product Management team.   Thanks to the GoldenGate Hands-on Lab team for putting on a great session!!! We will post more information about where you can find additional details on OpenWorld as they become public.

• Is this a reasonable way to handle getters/setters in a PHP class?

  - by Mark Biek

  I'm going to try something with the format of this question and I'm very open to suggestions about a better way to handle it. I didn't want to just dump a bunch of code in the question so I've posted the code for the class on refactormycode. base-class-for-easy-class-property-handling My thought was that people can either post code snippets here or make changes on refactormycode and post links back to their refactorings. I'll make upvotes and accept an answer (assuming there's a clear "winner") based on that. At any rate, on to the class itself: I see a lot of debate about getter/setter class methods and is it better to just access simple property variables directly or should every class have explicit get/set methods defined, blah blah blah. I like the idea of having explicit methods in case you have to add more logic later. Then you don't have to modify any code that uses the class. However I hate having a million functions that look like this: public function getFirstName() { return $this->firstName; } public function setFirstName($firstName) { return $this->firstName; } Now I'm sure I'm not the first person to do this (I'm hoping that there's a better way of doing it that someone can suggest to me). Basically, the PropertyHandler class has a __call magic method. Any methods that come through __call that start with "get" or "set" are then routed to functions that set or retrieve values into an associative array. The key into the array is the name of the calling method after get or set. So, if the method coming into __call is "getFirstName", the array key is "FirstName". I liked using __call because it will automatically take care of the case where the subclass already has a "getFirstName" method defined. My impression (and I may be wrong) is that the __get & __set magic methods don't do that. So here's an example of how it would work: class PropTest extends PropertyHandler { public function __construct() { parent::__construct(); } } $props = new PropTest(); $props->setFirstName("Mark"); echo $props->getFirstName(); Notice that PropTest doesn't actually have "setFirstName" or "getFirstName" methods and neither does PropertyHandler. All that's doing is manipulating array values. The other case would be where your subclass is already extending something else. Since you can't have true multiple inheritance in PHP, you can make your subclass have a PropertyHandler instance as a private variable. You have to add one more function but then things behave in exactly the same way. class PropTest2 { private $props; public function __construct() { $this->props = new PropertyHandler(); } public function __call($method, $arguments) { return $this->props->__call($method, $arguments); } } $props2 = new PropTest2(); $props2->setFirstName('Mark'); echo $props2->getFirstName(); Notice how the subclass has a __call method that just passes everything along to the PropertyHandler __call method. Another good argument against handling getters and setters this way is that it makes it really hard to document. In fact, it's basically impossible to use any sort of document generation tool since the explicit methods to be don't documented don't exist. I've pretty much abandoned this approach for now. It was an interesting learning exercise but I think it sacrifices too much clarity.

• Implementation of Nib project to Storyboard, Xcode

  - by Blake Loizides

  I have made a tabbed bar application in storyboard in xcode. I,m new to xcode. I got a Sample TableView XIB project from apple that I edited to my needs,The project has a UITableView that I Customized with Images, And with help of a certain forum member I was able to link up each image to a New View Controller. I tried to port or integrate My Nib Project Code to my StoryBoard Tabbed Bar Application.I thought I had everything right had to comment out a few things to get no errors, But the project only goes to a Blank Table View. Below are 2 links, 1 to my StoryBoard Tabbed Bar Application with the Table Code that I tried to integrate and the other My Successful Nib Project. Also is some code and pictures.

• How to copy text from Console2?

  - by GJ

  I just started using Console2 as an alternative to cmd.exe I can't figure out how to copy text from the console to the clipboard -- dragging over it with the mouse won't mark anything, and there is no option in the right-click menu to "mark" as in cmd.exe It must be terribly obvious but I guess I'm overlooking it... :(

• Spaces in SETX PATH command

  - by Jeremy Stein

  Suppose my PATH is C:\WINDOWS\system32\;C:\Program Files\Important\ SET NEW_PATH=C:\My\Dir\ SETX PATH "%PATH%;%NEW_PATH%" Results in a path of: C:\WINDOWS\system32\;C:\Program Files\Important\;C:\My\Dir" Notice the quotation mark at the end of the path. It's as though the backslash at the end of %NEW_PATH% escaped the final quote mark. I need the quotation marks because I have spaces in my path, but I don't want backslashes to be interpreted as escape characters. What's the right way to include my PATH in the call to SETX?

• marking text in Windows 7's command prompt

  - by Jonathan

  I use Windows 7's command prompt (cmd.exe) for various tasks. In order to copy text from it, I right click and choose Mark, and then mark the text I want to copy. Sometimes while doing this, the marking doesn't stick. The minute I release the left mouse button after marking the text, the marking disappears. This has happened on every Windows 7 installation I've ever installed. How do I solve this?
