• WSS 3.0/MOSS 2007 Active Directory Forms Based Authentication PeoplePicker no users found

  - by John Haigh

  WSS 3.0/MOSS 2007 Active Directory Forms Based Authentication PeoplePicker no users found After finding these steps online from http://dattard.blogspot.com/2008/11/active-directory-forms-based.html in order to setup Active Directory Forms Based Authentication I was all set to complete this task, except for one problem. These steps are missing one very important vital step in order for FBA to work with Active Directory. A supplement to step 3 before granting access in step 5 through the people picker. You need to specify the Active Directory Provider Name to the people picker, otherwise you will not be able specify users through the Policy for Web Application. <PeoplePickerWildcards>       <clear />          <add key="ADMembershipProvider" value="%" />     </PeoplePickerWildcards> Recently we needed to use Forms Based Authentication with Active Directory from an Extranet. This is how we got it to work. 1. Extend the Web Application Instead of tweaking the internal web app, Extend the web application you want to expose to the Extranet, giving it the required host headers etc. 2. Configure SharePoint Central Admin to use FBA for the "new" Web Applications Login to SharePoint Central Admin Go to Application Management / Application Security / Authentication Providers and Change the Web Application to the one which needs to be configured for Forms Based Authentication Click zone / default, change authentication type to forms and enter ActiveDirectoryMemebershipProvider under membership provider name ( for example , "ADMembershipProvider") and save this change 3. Update the web.config of SharePoint Central admin site under configuration node <connectionStrings> <add name="ADConnectionString" connectionString="LDAP://DynamicsAX.local/CN=Users,DC=DynamicsAX,DC=local /> </connectionStrings> under system.web node <membership defaultProvider="ADMembershipProvider"> <providers> <add name="ADMembershipProvider" type="System.Web.Security.ActiveDirectoryMembershipProvider,System.Web,Version=2.0.0.0,Culture=neutral,PublicKeyToken=b03f5f7f11d50a3a" connectionStringName="ADConnectionString" connectionUsername="xxx" connectionPassword="yyy" enableSearchMethods="true" attributeMapUsername="sAMAccountName"/> </providers> </membership> 4.Update the web.config of SharePoint Web application Repeat step 3 for the web.config of the SharePoint webapplication to be configured for Forms Based Authentication Change the authentication in web.config to <authentication mode="Forms"> <forms loginUrl="/_layouts/login.aspx"></forms> </authentication> 5. Grant Access on the extended Web Application Your extranet web application is now configured to use FBA. However, until users, who will be accessing the site via FBA, are given permissions for the site, it will be inaccessible to them. To get started, open your browser and navigate to your farm’s Central Administration site. Click on Application Management and then click on Policy for Web Application. Make sure that you are working on the extranet web application. Do the following steps: Click on Add Users. In the Zones drop down, select the appropriate Extranet zone. IMPORTANT: If you select the incorrect zone, you may not be able to resolve user names. Hence, the zone you select must match the zone of the web application that is configured to use FBA. Click the Next button. In the Users edit box, type the name of the FBA user whom you wish to have full control for the site. Click the Resolve link next to the Users edit box. If the web application's FBA information has been configured correctly, the name will resolve and become underlined. Check the Full Control checkbox. Click the Finish button.

• Queyring container with Linq + group by ?

  - by Prix

  public class ItemList { public int GuID { get; set; } public int ItemID { get; set; } public string Name { get; set; } public entityType Status { get; set; } public class Waypoint { public int Zone { get; set; } public int SubID { get; set; } public int Heading { get; set; } public float PosX { get; set; } public float PosY { get; set; } public float PosZ { get; set; } } public List<Waypoint> Routes = new List<Waypoint>(); } I have a list of items using the above class and now I need to group it by ItemID and join the first entry of Routes of each iqual ItemID. So for example, let's say on my list I have: GUID ItemID ListOfRoutes 1 23 first entry only 2 23 first entry only 3 23 first entry only 4 23 first entry only 5 23 first entry only 6 23 first entry only 7 23 first entry only Means I have to group entries 1 to 7 as 1 Item with all the Routes entries. So I would have one ItemID 23 with 7 Routes on it where those routes are the first element of that given GUID Routes List. My question is if it is possible using LINQ to make a statment to do something like that this: var query = from ItemList entry in myList where status.Contains(entry.Status) group entry by entry.ItemID into result select new { items = new { ID = entry.ItemID, Name = entry.Name }, routes = from ItemList m in entry group m.Routes.FirstOrDefault() by n.NpcID into m2 }; So basicly I would have list of unique IDS information with a inner list of all the first entry of each GUID route that had the same ItemID. <<< UPDATE: This would be an example of public List<ItemList> myList = new List<ItemList>(); data: GUID ItemID ListOfRoutes 1 20 Routes[1] 2 20 Routes[2] 3 20 Routes[3] 4 20 Routes[4] 5 20 Routes[5] 6 55 Routes[6] 7 55 Routes[7] 8 55 Routes[8] 9 1 Routes[9] 10 1 Routes[10] As you can see GUID is unique, ItemID can reapeat it self. Each GUID has a Routes list and all routes list have a minimum of 1 entry and above. Routes example. Routes[1] have: Entry Zone SubID Heading PosX PosY PosZ 1 1200 0 100 1029.32 837.21 29.10 2 1200 0 120 1129.32 537.21 29.10 3 1200 0 180 1229.32 137.21 29.10 4 1200 0 360 1329.32 437.21 29.10 5 1200 0 100 1429.32 637.21 29.10 Routes[2] have: Entry Zone SubID Heading PosX PosY PosZ 1 100 0 10 129.32 437.21 29.10 So what I want to do is a list of all entries I have on myList grouped by ItemID maintainning the fields ItemID and Name ... and a new field or item that will have all the first elements of Routes of those GUIDs. For example ItemID 20 would produce the follow result: ItemID, Name, ListOfRoutes This ItemID ListOfRoutes would contain Routes[1] first entry: Entry Zone SubID Heading PosX PosY PosZ 1 1200 0 100 1029.32 837.21 29.10 Routes[2] first entry: Entry Zone SubID Heading PosX PosY PosZ 1 100 0 10 129.32 437.21 29.10 Routes[3], Routes[4], Routes[5] first entries. Example of how myList is feeded: ItemList newItem = new ItemList(); newItem.GUID = GUID; newItem.ItemID = ItemID; newItem.Name = Name; newItem.Status = Status; // Item location ItemList.Waypoint itemLocation = new ItemList.Waypoint(); itemLocation.SubID = SubID; itemLocation.Zone = Zone; itemLocation.Heading = convertHeading(Heading); itemLocation.PosX = PosX; itemLocation.PosY = PosY; itemLocation.PosZ = PosZ; itemLocation.Rest = Rest; newItem.Routes.Add(itemLocation); myList.Add(newItem);

• How to implement Cocoa copyWithZone on derived object in MonoMac C#?

  - by Justin Aquadro

  I'm currently porting a small Winforms-based .NET application to use a native Mac front-end with MonoMac. The application has a TreeControl with icons and text, which does not exist out of the box in Cocoa. So far, I've ported almost all of the ImageAndTextCell code in Apple's DragNDrop example: https://developer.apple.com/library/mac/#samplecode/DragNDropOutlineView/Listings/ImageAndTextCell_m.html#//apple_ref/doc/uid/DTS40008831-ImageAndTextCell_m-DontLinkElementID_6, which is assigned to an NSOutlineView as a custom cell. It seems to be working almost perfectly, except that I have not figured out how to properly port the copyWithZone method. Unfortunately, this means the internal copies that NSOutlineView is making do not have the image field, and it leads to the images briefly vanishing during expand and collapse operations. The objective-c code in question is: - (id)copyWithZone:(NSZone *)zone { ImageAndTextCell *cell = (ImageAndTextCell *)[super copyWithZone:zone]; // The image ivar will be directly copied; we need to retain or copy it. cell->image = [image retain]; return cell; } The first line is what's tripping me up, as MonoMac does not expose a copyWithZone method, and I don't know how to otherwise call it. Update Based on current answers and additional research and testing, I've come up with a variety of models for copying an object. static List<ImageAndTextCell> _refPool = new List<ImageAndTextCell>(); // Method 1 static IntPtr selRetain = Selector.GetHandle ("retain"); [Export("copyWithZone:")] public virtual NSObject CopyWithZone(IntPtr zone) { ImageAndTextCell cell = new ImageAndTextCell() { Title = Title, Image = Image, }; Messaging.void_objc_msgSend (cell.Handle, selRetain); return cell; } // Method 2 [Export("copyWithZone:")] public virtual NSObject CopyWithZone(IntPtr zone) { ImageAndTextCell cell = new ImageAndTextCell() { Title = Title, Image = Image, }; _refPool.Add(cell); return cell; } [Export("dealloc")] public void Dealloc () { _refPool.Remove(this); this.Dispose(); } // Method 3 static IntPtr selRetain = Selector.GetHandle ("retain"); [Export("copyWithZone:")] public virtual NSObject CopyWithZone(IntPtr zone) { ImageAndTextCell cell = new ImageAndTextCell() { Title = Title, Image = Image, }; _refPool.Add(cell); Messaging.void_objc_msgSend (cell.Handle, selRetain); return cell; } // Method 4 static IntPtr selRetain = Selector.GetHandle ("retain"); static IntPtr selRetainCount = Selector.GetHandle("retainCount"); [Export("copyWithZone:")] public virtual NSObject CopyWithZone (IntPtr zone) { ImageAndTextCell cell = new ImageAndTextCell () { Title = Title, Image = Image, }; _refPool.Add (cell); Messaging.void_objc_msgSend (cell.Handle, selRetain); return cell; } public void PeriodicCleanup () { List<ImageAndTextCell> markedForDelete = new List<ImageAndTextCell> (); foreach (ImageAndTextCell cell in _refPool) { uint count = Messaging.UInt32_objc_msgSend (cell.Handle, selRetainCount); if (count == 1) markedForDelete.Add (cell); } foreach (ImageAndTextCell cell in markedForDelete) { _refPool.Remove (cell); cell.Dispose (); } } // Method 5 static IntPtr selCopyWithZone = Selector.GetHandle("copyWithZone:"); [Export("copyWithZone:")] public virtual NSObject CopyWithZone(IntPtr zone) { IntPtr copyHandle = Messaging.IntPtr_objc_msgSendSuper_IntPtr(SuperHandle, selCopyWithZone, zone); ImageAndTextCell cell = new ImageAndTextCell(copyHandle) { Image = Image, }; _refPool.Add(cell); return cell; } Method 1: Increases the retain count of the unmanaged object. The unmanaged object will persist persist forever (I think? dealloc never called), and the managed object will be harvested early. Seems to be lose-lose all-around, but runs in practice. Method 2: Saves a reference of the managed object. The unmanaged object is left alone, and dealloc appears to be invoked at a reasonable time by the caller. At this point the managed object is released and disposed. This seems reasonable, but on the downside the base type's dealloc won't be run (I think?) Method 3: Increases the retain count and saves a reference. Unmanaged and managed objects leak forever. Method 4: Extends Method 3 by adding a cleanup function that is run periodically (e.g. during Init of each new ImageAndTextCell object). The cleanup function checks the retain counts of the stored objects. A retain count of 1 means the caller has released it, so we should as well. Should eliminate leaking in theory. Method 5: Attempt to invoke the copyWithZone method on the base type, and then construct a new ImageAndTextView object with the resulting handle. Seems to do the right thing (the base data is cloned). Internally, NSObject bumps the retain count on objects constructed like this, so we also use the PeriodicCleanup function to release these objects when they're no longer used. Based on the above, I believe Method 5 is the best approach since it should be the only one that results in a truly correct copy of the base type data, but I don't know if the approach is inherently dangerous (I am also making some assumptions about the underlying implementation of NSObject). So far nothing bad has happened "yet", but if anyone is able to vet my analysis then I would be more confident going forward.

• Oracle TIMESTAMP w/ timezone data type confusion

  - by JuiceBox1337

  When would you use TIMESTAMP w/ timezone as opposed to TIMESTAMP w/ local time zone? When data is stored in a column of data type TIMESTAMP w/ local tz, the data is normalized to the database time zone, and the time zone displacement is not stored as part of the column data. When users retrieve the data, Oracle returns it in the users' local session time zone. Isn't that much more useful? I can't think of a reason why I'd want to use TIMESTAMP w/ timezone and get back some gobble gook with a UTC offset.

• Summary of the Solaris 11 webcast's livechat QnA session

  - by Karoly Vegh

  This is a followup post to the previous summary on the "What's new with Solaris 11 since the launch" webcast. That webcast has had a chatroom for a live Questions and Answers session running. I went through the archive of those and compiled a list of some of the (IMHO) most relevant and most frequently asked questions, I'd like to share. This is the first part, covering the QnA of Session I and II of the webcast, in a followup post we can have a look of the rest of the sessions if required - let me know in the comments. Also, should you have questions, as usual, feel free to ask those there, too.  ...and here come the answered questions:  When will Exadata be based on Solaris in place of Oracle Enterprise Linux?Exadata offers both Solaris 11 or Oracle Enterprise Linux.  The choice can be made at deployment time based on your OS needs.What are all other benefits and futures avilable in solaris 11 (cloud O.S.) compared to cloud based Red Hat Linux and Windows?suggest you check out our cloud white paper for a view of this. Also the OTN Solaris 11 page has some good articles. Here are the links:  http://www.oracle.com/technetwork/server-storage/solaris11/documentation/o11-106-sol11-cloud-501066.pdf http://www.oracle.com/technetwork/server-storage/solaris11/overview/index.htmlWill 11.1 have a more complete IPS respository for Oracle and FOSS software?Yes, we are adding additional packages to the various package repositories. Since Solaris 11 was launched, both the Oracle Solaris Studio tools as well as Oracle Solaris Cluster have been made available along with numerous new FOSS packages. We will continue to be adding additional Oracle products and open source packages in the future. Will Exadata be based on Sparc in place of intel-amd x86 in next future ?We can't publically discuss futures, but we actually have a SPARC version of Exadata today, it's called SuperCluster, this is such a powerfull multipurpose system that it actually have multiple personalities built into one system: Exadata, Exalogic, and it can be a general purpose platform if you want. Have I understood this right? Livepatching KSplice-style is coming to Solaris 11 too?We're looking at that for certain types of Solaris patches in the future.Will there be a security framework like SST/JASS for Solaris 11?We can't talk about the future projects on a public forum, but we recognize the need for SST/JASS and want to address this as soon as possible. On the other side there are a whole bunch of "best practices" that are now embedded into Solaris 11 by default, so out of the box Solaris 11 should already address part of what SST/JASS gave you. (For example we did a lot of work on improving the auditing performance so that we can now have it turned on by default). On x86 can install VirtualBox in a Zone and use that to host other OSes.Yes, this was one of the first things we made sure would work when we acquired VirtualBox when we were still Sun Microsystems. If I have a Solaris 11 Control Domain on a T-series, can I run a Solaris 10 Ldom with Solaris 8 branded containers?Yes, you can.Is Oracle Solaris free or do we need to purchase?Solaris is free, the entitlement to run it comes either with a Sun system (new or historical) or for 3rd party systems the entitlement comes with a support contract. Note that for production use you will be expected to get a support contract. If you don't want to use the Solaris system (Sun or 3rd party) for production use (i.e. development) you can get an OTN license on the Oracle Technical Network website. Will encryption and deduplication both work on a share?This should work at the same time. What approaches does Solaris use to monitor usage?There are many different tools in Solaris to monitor usage. The main ones are the "stats" (vmstat, mpstat, prstat, ...), the kstat interface, and DTrace (to get details you couldn't see before). And then there are layered tools that can interface with these tools (Ops Center, BMC, CA, Tivoli, ...) Apart little-endian, big-endian how is it easy to port Solaris applications on Sparc to x86 and vice-versa ?Very easy. Except for certain hardware specific applications (those that utilize hardware specific drivers), all of the same Oracle Solaris APIs exist for all architectures. Is IPS based patching aware of the fact that zones can reside on ZFS and move from one physical server to another ?IPS is definitely aware of zones and uses ZFS to support boot environments for non-global zones in the same way that's used for the global zone. With respect to moving a zone from one physical server to another, Solaris 11 supports to the same zone attach/deattach method that was introduced in Solaris 10. Is vnic support in Ldoms planned?This is currently being investigated for a future LDOM release. Is it possible with the new patching system to build a system later with the same patch level as a system built a few months earlier?Yes, you can choose/define exactly which version should go to the system and it will always put the same bits in place. The technical answer is that you choose the version of the "entire" package you want on the system and the rest flows from there. Is it in the plans to allow zones to add/remove zpools to running zones dynamically in future updates?Work in this area is currently under investigation. Any plans to realese Solaris 11 source code? i.e. opensolaris?We currently can't comment on publicly releasing the source code. If you need/want this access please let your Oracle account team know. What about VirtualBox and Solaris11 for virtualization?Solaris 11 works great with VirtualBox, as both a client and a host system. Will Oracle DB software eventually be supplied as IPS packages? When?We don't have a date yet but this is actively being worked on. What are the new artifacts in Oracle Solaris 11 than the previous versions?There are quite a few actually. The best start is to look at our "Evaluate Solaris 11" page, and there you also can find a Transition Guide. http://www.oracle.com/technetwork/server-storage/solaris11/overview/evaluate-1530234.html So, this seems just like RedHat's YUM environment?IPS offers certain features beyond those in YUM or other packaging systems. For example, IPS works with ZFS and Solaris Boot Environments to provide a safe environment for software lifecycle management so that changes can be reverted by switching to an older boot environment. With Zones on solaris 11, can I do paravirtualitation?The great thing about zones is you don't *need* paravirtualization. You're making the same direct kernel calls that you would outside of a zone.  It's an incredibly significant performance win over hypervisor-based virtualization. Are zones/containers officially supported to run Oracle Databases?  EBIZ?Hi Calvin, the answer is yes, here is the support matrix for DB:  http://www.oracle.com/technetwork/database/virtualizationmatrix-172995.html I've found some nasty bugs in Solaris 11 (one of which today) that have been fixed in community forks (i.e., Illumos). Will Oracle ever restart collaboration with the community?We continue to work with the community, just not as open on all projects as we did before (For example IPS is an open project) and the source of more than half of the Solaris packages is posted on our opensource websites. I can't comment on what we will do in the future. And with regards to bugs please file them through the support organization and we will get them resolved. Is zpool vdev removal on-the fly now possible ?This issue is actively being investigated although we don't have a date for when this feature will be available. Is pgstat now the official replacement for corestat ?It's intended to provide similar functionality Where are the opensource website?For Oracle Solaris, visit http://www.oracle.com/technetwork/opensource/systems-solaris-1562786.html As a cloud-scale virtualization, is it going to be easier to move zones between machines? maybe even automatic in case of a hardware failure?Hi Gashaw, we already have customers that have implemented what they refer to as "flying zones" that they can move around very easily. They use Solaris Cluster to do this. What about VMware vMotion like feature?We have secure live migration with both Logical Domains on SPARC T series systems, and with Oracle VM on x86 systems. When running Solaris 10/11 on an enterprise server with a lot of zones, what are best practises commands to show the system is running fine? (has enough hardware resources). For example CPU / Memory / I/O / system load. What are the recommended values?For Solaris 11, look into the new zonestat(1M) command that provides a great deal of information about zone utilization. In addition, there is new work underway in providing additional observability in areas such as per-zone file system I/O. Java optimizations done with Solaris 11? For X86 platforms too? Where can I find more detail about this?There is lots of work that go into optimizing Java for Oracle Solaris 10 & 11 on both SPARC and x86. See http://www.oracle.com/technetwork/articles/servers-storage-dev/solarisforjavadevelop-168642.pdf What is meant by "ZFS Shadow Migration"?It's a way to migrate data from another file system to ZFS: http://docs.oracle.com/cd/E23824_01/html/E24456/filesystem-3.html Is flash archive available with S11?Flash archive is not.  There is a procedure for disaster recovery, and we're working on a modern archive-based deployment tool for a future update.  The disaster recovery tool is here: http://www.oracle.com/technetwork/articles/servers-storage-admin/o11-091-sol-dis-recovery-489183.html  You can also use Distribution Constructor to build common golden images. Will solaris 11 be available on the ODA soon?The idea's under evaluation -- we'll share your interest with the team. What steps can be taken to ensure that breaches of security are identified quickly?There are a number of tools, including the "bart" tool and "pkg verify" to ensure that software has not been compromised.  Solaris Audit can also be used to detect unauthorized access.  You can also use Immutable Zones to protect against compromise.  There are a wide variety of security tools, and I've covered only a few. What is the relation from solaris to java 7 speed optimization?There is constant work done between the Oracle Solaris and Java teams on performance optimizations. See http://docs.oracle.com/javase/7/docs/technotes/guides/vm/performance-enhancements-7.html for examples. What is the difference in the Solaris 11 installation compared to solaris 10 ? where i can find the document describing basic repository concepts ?The best place to start is: http://www.oracle.com/technetwork/server-storage/solaris11/index.html Hope you found the post useful. For questions, input, requests for the second half of the QnA, please find the comment section below.  -- charlie

• Bind9 Debian Not responding

  - by Marc

  Im trying to set up a webserver with Bind9, apache2 on Debian 6. I am trying to learn to do it manualy so I do not have any control panels or anything just the command line. I have a domain name lets call it www.example.com I want a virtual host setup so that I can have multiple websites with different names on my server. I have ns1.example.com and ns2.example.com registered at my servers IP (123.456.789.12). Below is my Bind9 named.conf.options options { directory "/var/cache/bind"; // If there is a firewall between you and nameservers you want // to talk to, you may need to fix the firewall to allow multiple // ports to talk.

• How TiVo is messing up customer support.

  - by James Fleming

  Ok,  So I've gotten a TiVo and overall, I'm happy, but there have been issues and I suspect I've a defective unit. - Now the nice folks after many service calls were happy to swap it out, and to ensure continuity of service, they sent me a new unit (after a $109 deposit).  That was yesterday. Today, when we go to watch a little TV, and wait for our replacement unit to arrive we find our TiVo service has been suspended. WTF? They have an exchange program, but your unit your waiting to exchange is as dead as a doornail until the replacement arrives. How hard is it to keep the old unit active for an extra week? Here is the exchange w/Tivo below... You are currently number 1 in the queue. We apologize for the delay. We will assign you to an agent as soon as one is available.The average amount of time a customer has to wait is 00:13.  Kaylene (Listening)  Kaylene: Thank you for contacting TiVo! My name is Kaylene. So that I may better assist you, are you an existing customer?  james Fleming: yes I am, but I'm now having second thoughts about being one    Kaylene: Thank you for verifying your information. How may I assist you today James?  james Fleming: I've been having issues w/a tivo box & I'm getting a replacement sent out to me (after paying an additional deposit) and now my current unit is no longer activated  Kaylene: I can help you today!  Kaylene: When we process an exchange we do transfer over the service to the replacement box so it is active and ready to go when you receive it.  james Fleming: which is to say you also make my current box worthless until such time I receive a new box?!?!?  Kaylene: I apologize that your original box was deactivated so we could activate your replacement box.  james Fleming: Why on Earth would I bother to pay in advance for a new box if you were going to kill my existing box.  Kaylene: What features are you needing to use on your current box?  james Fleming: I need to be able to access my netflix subscription (if I'm lucky enough to have it work without rebooting)  Kaylene: Can I have you verify the TiVo Service Number of your TiVo box please?  james Fleming: 7460011906979b4  Kaylene: We have your current box temporary service but not all features are available with temporary service as it is not paid for service.  Kaylene: If you like I can transfer your service back to your current box for now. Then once you receive the new box you will have to call in and have the service transferred back to the new box.  james Fleming: Not paid for? Let's see> one tivo box + 3 year service plan + monthly service + $109 deposit on a second box = what?  Kaylene: Would you like me to transfer your service back to your current box?  james Fleming: Yes - that would be helpful  Kaylene: All you will need to do is contact us again once you receive the new box so we can transfer it back.  Kaylene: I have put your service back on TiVo box 7460011906979b4.  james Fleming: What would also be helpful is your firm informing me to how you'd be cutting service in the interim.  james Fleming: Again - I opted to pay to have a second box delivered BEFORE returning the box I have - thus trying to have a continuity of service..  Kaylene: This is not something we normally do so it is important when you contact us to transfer the service back to the new box when you receive it that you reference this case number: 110622-006089.  Kaylene: I apologize about the inconvenience. You may need  force a few connections for the box to recognize the service again.  james Fleming: If it's not something you normally do than WHY would you have a $109 fee and a term for the service.  james Fleming: I am not mad at you, but your company is not impressing me and I'm blogging about this experience  Kaylene: Again I apologize about the inconvenience but you should be good to go now. Is there anything else I can help you with today?  james Fleming: so I need to go through the re-actviate process or is that somethign you do  Kaylene: When you receive the new TiVo box you need to contact us so we can transfer the service to the new box for you.  james Fleming: sure  Kaylene: Is there anything else I can help you with today James?  james Fleming: Nope - please email this transcript to me  Kaylene: I apologize but we do not have the ability to e-mail you a copy of this transcript. You can view it online at  http://www.tivo.com when you sign into your account or you can copy and paste it now to save it.  Kaylene: Thank you for contacting TiVo today. Your reference number for our conversation is 110622-006089. You can save this for your records, and if necessary, provide this to a later agent to pull up what we discussed. There will be a brief satisfaction survey emailed to you. We would appreciate any feedback on your TiVo Chat Support experience today.  Kaylene: Thank you for using TiVo Chat and have a great day James! Good-bye.  Kaylene has disconnected.

• 10 steps to enable &lsquo;Anonymous Access&rsquo; for your SharePoint 2010 site

  - by KunaalKapoor

  What’s Anonymous Access? Anonymous access to your SharePoint site enables all visitors to view your SharePoint site anonymously without having to log in. With this blog I’d like to go through an easy step wise procedure to enable/set up anonymous access. Before you actually enable anonymous access on the site, you’ll have to change some settings at the web app level. So let’s start with that: Prerequisite(s): 1. A hosted SharePoint 2010 farm/server. 2. An existing SharePoint site. I just thought I’d mention the above pre-reqs, since the steps mentioned below would’nt be valid or a different type of a site. Step 1: In Central Administration, under Application Management, click on the Manage web applications. Step 2: Now select the site you want to enable anonymous access and click on the Authentication Providers icon. Step 3: On the modal window click on the Default zone. Step 4: Now under the Edit Authentication section, check Enable anonymous access and click Save. This is basically to make the Anonymous Access authentication mechanism available at the web app level @ IIS. Now, web application will allow anonymous access to be set. 5. Going back to Web Application Management click on the Anonymous Policy icon. Step 6: Also before we proceed any further, under the Anonymous Access Restrictions (@ web app mgmt.) select your Zone and set the Permissions to None – No policy and click Save. Step 7:  Now lets navigate to your top level site collection for the web application. Click the Site Actions > Site Settings. Under Users and Permissions click Site permissions. Step 8: Under Users and Permissions, click on Site Permissions. Step 9: Under the Edit tab, click on Anonymous Access. Step 10: Choose whether you want Anonymous users to have access to the entire Web site or to lists and libraries only, and then click on OK. You should now be able to see the view as below under your permissions Also keep in mind: If you are trying to access the site from a browser within the domain, then you’ll need to change some browser settings to see the after affects. Normally this is because the browsers (Internet Explorer) is set to log in automatically to intranet zone only , not sure if you have explicitly changed the zones and added it to trusted sites. If this is from a box within your domain please try to access the site by temporarily changing the Internet Explorer setting to Anonymous Logon on the zone that the site is added example "Intranet" and try . You will find the same settings by clicking on Tools > Internet Options > Security Tab.

• Internet Explorer Security: How to Configure Settings

  Before jumping into the steps that are needed to configure Internet Explorer's security settings, let us first take a closer look at the four separate security zones that Microsoft has established for the browser. You will be able to tweak the settings of each of these four zones when we get into the configuration part of this tutorial, so it is best that you learn what they represent first. Internet Explorer Security Zones Internet Zone This Internet Explorer security zone refers to websites that are not on your computer or are not designated to your local intranet, which we will discuss in ...

• Dynamic Bind9 + DHCP

  - by AcidRod75

  i have been working on setup a server for my internal network, so far i have a working isc-dhcp-server that can upgrade a chrooted BIND9 (on the same machine), i need to add some static entries on the DNS, so users can resolve the websites that resides in our DMZ. What i had tryed all ready was to modify the /etc/bind/named.conf.local with this info: // // Do any local configuration here // // Consider adding the 1918 zones here, if they are not used in your // organization //include "/etc/bind/zones.rfc1918"; key DHCP_UPDATER { algorithm HMAC-MD5.SIG-ALG.REG.INT; secret "MySuperSecretHash"; (this is not the real value BTW) }; zone "quality.internal" IN { type master; file "/var/lib/bind/quality.internal.db"; allow-update { key DHCP_UPDATER; }; }; zone "0.10.10.in-addr.arpa" { type master; file "/var/lib/bind/rev.10.10.0.in-addr.arpa"; allow-update { key DHCP_UPDATER; }; }; logging { channel query.log { file "/var/log/named/query.log"; severity debug 3; }; category queries { query.log; }; }; --- EOF ---- then i added this 2 entries: zone "ourserver.internal" IN { type master; file "/var/lib/bind/ourserver.internal.db"; }; zone "0.16.172.in-addr.arpa" { type master; file "/var/lib/bind/rev.172.16.0.in-addr.arpa"; }; ---- EOF ---- So.. i created the files ourserver.internal.db and rev.172.16.0.in-addr.arpa placed them BOTH in /var/lib/bind/ and changed the permisions so the bind user can access them, restated the service... when i do a NSLOOKUP www.ourserver.internal i get: Server: 127.0.0.1 Address: 127.0.0.1#53 ** server can't find www.ourserver.internal: NXDOMAIN BUT when i do a reverse lookup.... Server: 127.0.0.1 Address: 127.0.0.1#53 5.0.16.172.in-addr.arpa name = www.ourserver.internal I do not understand what's wrong. Some help with this will save me from installing a new DNS server at the DMZ JUST to host internal site names- TY in advance BTW: the server i'm using has Ubuntu Server 11.10 fully patched.

• Trying to get DNS services running on Windows Server 2008 R2, what am I getting wrong ?

  - by LaserBeak

  Ok, So I am basically trying to get a home server pc up that will provide Domain name services, act as Mail server and web server. I have one static IP, well it's not officially static but hasn't changed in two years so I'll call it static. I have done the following: Configured router NAT/virtual port forward UDP/TCP port 53 to the internal IP of my server 192.168.1.16, in adapter settings specified the manual settings: 192.168.1.16 IP, gateway 192.168.1.1, Subnet: 255.255.255.0 and loopback DNS: 127.0.0.1 Using my public my public IP Checked using http://www.canyouseeme.org/ that port 53 is open and is not being blocked by my ISP. It can see services on this port. Registered Domain name (mydomain.com.au) Updated whois database through the domain registrars site and registered NameServer names: ns0.mydomain.com.au and ns2.mydomain.com.au, both have been associated with my single public IP. (Waited 24 hours) Update the nameserver for mydomain.com.au: primary ns0.mydomain.com.au secondary: ns2.mydomain.com.au (waited 24+ hours) Installed Server 2008 R2, install web server role and DNS role. Webserver works when I enter my public IP into browser of any PC/mobile, get IIS7 welcome page. In DNS server: Created new forward lookup zone: ; ; Database file mydoman.com.au.dns for mydomain.com.au zone. ; Zone version: 10 ; @ IN SOA mydomain.com.au. mydomain.testdomain.com. ( 10 ; serial number 900 ; refresh 600 ; retry 86400 ; expire 3600 ) ; default TTL ; ; Zone NS records ; @ NS ns0.mydomain.com.au. @ NS ns1.mydomain.com.au. ; ; Zone records ; @ A 192.168.1.16 www A 192.168.1.16 The Domain name services will however not work, the whois database updated with ns0.mydomain.com.au etc. but when I type in my site name www.mydomain.com.au from an external machine it will not open site and I can't even ping it (Can't find host) When I check the ns0.mydomain.com.au NS record using a tool Like: http://www.squish.net/dnscheck/ I get: Security: Server ns0.mydomain.com.au (XXX.XXX.XXX.XX <- my public IP) is recursive Domain exists but there is no such record Any ideas, thanks...

• How do I sync music to my Sony Walkman (Z Series) using Rhythmbox?

  - by Mark Paskal

  I have recently purchased the new Walkman Z from Sony. I can transfer music by mounting it as a drive, but I would prefer to use Rhythmbox to do so. My other Android devices and MP3 players from the past have always just shown up without any tweaking. Using Nautilus to transfer the files is possible but for some reason Nautilus still makes a trash folder on removable drives. Deleting the trash folder anew is really annoying to do every time I delete music from the device. How can I use Rhythmbox to transfer and remove songs instead?

• Can't control connection bit rate using iwconfig with Atheros TL-WN821N (AR7010)

  - by Paul H

  I'm trying to reduce the connection bit rate on my Atheros TP-Link TL-WN821N v3 usb wifi adapter due to frequent instability issues (reported connection speed goes down to 1Mb/s and I have to physically reconnect the adapter to regain a connection). I know this is a common problem with this device, and I have tried everything I can think of to fix it, including using drivers from linux-backports; compiling and installing a custom firmware (following instructions on https://wiki.debian.org/ath9k_htc#fw-free) and (as a last resort) using ndiswrapper. When using ndiswrapper, the wifi adapter is stable and operates in g mode at 54Mb/s (whilst when using the default ath9k_htc module, the adapter connects in n mode and the bit rate fluctuates constantly). Unfortunately, with this setup I have to run my processor using only one core, since using SMP with ndiswrapper causes a kernel oops on my system. So I want to lock my bit rate to 54Mb/s (or less, if need be) for connection stability, using the ath9k_htc module. I've tried 'sudo iwconfig wlan0 rate 54M'; the command runs with no error but when I check the bit rate with 'sudo iwlist wlan0 bitrate' the command returns: wlan0 unknown bit-rate information. Current Bit Rate:78 Mb/s Any ideas? Here's some info (hopefully relevant) on my setup: Xubuntu (12.04.3) 64bit (kernel 3.2.0-55.85-generic) using Network Manager.

• What to do with DATETIMEOFFSET?

  - by GavinPayneUK

  Someone asked me today if the time zone of a specific instance of SQL Server could be changed to match the country which that instance served. Some database products allow you to set this at an engine level which made me wonder if your data’s time fields “move” with the time zone setting of the database server instance?  If something was logged as happening at 9am Paris time it happened then, if I change my database server parameters did that event now happen at 9am New York time?  Perhaps...(read more)

• Slow tranfer to external USB3 hard drive

  - by JMP

  Trying to backup data from hard drive before reloading windows following some issue with its load. Having trouble with the file transfer to a USB3/2 external hard drive NTFS. Getting transfer speed of about 116.7kB/sec. In other words its taking about 5 hours to tranfer 1.4GB. I've got about 80GB to go. So the transfer is going to take 11days. Seems a little on the slow side. Am I missing something? Is there a way to make this faster. No issue with the external drive tranferring this amount in windows. But don't have that option at the moment.

• Windows 2003 Domain Controller Very Upset about NIC Teaming

  - by Kyle Brandt

  I set up BACS (Broadcom Teaming) to team two NIC on a Windows 2003 Active Directory Domain Controller. Networking still works okay, I can ping the gateway etc, but both DNS and Active Directory fail to start with various 40xx errors. The team that I created is Smart load Balancing with Failover, with one backup and only one in smart load balancing (So really it is just failover). I have the team the same IP address that the single active NIC had before. Anyone seen this before, or have any ideas what the problem might be?

• Installation of Active Directory on separate VM from DNS does not entierly work - not sure why

  - by René Kåbis

  Not sure what I am doing wrong here. I have a moderately midrange server (16 cores, 2Ghz, 32GB ECC REG RAM, 6TB storage, nothing too extreme) where I am running Hyper-V (Server 2012 R2 Enterprise) in order to provision virtual machines. So why an AD separate from DNS? I want redundancy. I want to be able to move VMs and back them up individually and not have too many services on any one VM. I have already provisioned a VM with DNS, and have set it up right -- essentially, I have: Set up Static IP’s for everyone involved. Installed the DNS service on the DNS VM. Created a forward lookup zone and a reverse lookup zone (primary zone) xyz.ca Configured the zones to use nonsecure and secure dynamic updates (i will change this to secure later after the domain controller is online). Created a A record for the DC in the forward lookup zone (and a reverse ptr) Changed DC’s DNS server (network settings) to the new DNS server. Checked that I can ping the dns server from the new DC by hostname. When I went ahead and did a DCpromo on the DC, and un-cheked the “install DNS” option, everything seemed to go well (no error messages), but I saw no changes on the DNS server whatsoever (no additional settings). Plus, the DNS server seems to be unable to join the domain, as it claims that the domain is not discoverable. As a final note, I do run Symantec Endpoint Protection, which includes a firewall and most settings set as default. I have not yet tried turning this off, but my experience has been that if a service would open up a port on a Windows firewall, it would do the same through Symantec. There is pretty tight integration these days with corporate-class AV and Windows. I have a template vhdx fully set up (just short of any special roles and features) that I can use to replace the current AD VM with, so doing this all over again is not too much skin off of my nose.

• BIND9 server types

  - by aGr

  I was configuring DNS on my server using BIND9, everything seems to work, but I have a question regarding my config file. I've ended up with this configuration in /etc/bind/named.conf.local zone "example.com" { type master; file "/etc/bind/db.example.com"; allow-transfer { 192.168.1.1; }; }; zone "1.168.192.in-addr.arpa" { type master; notify no; file "/etc/bind/db.192"; allow-transfer { 192.168.1.1; }; }; forwarders { 10.253.22.140; 10.253.22.141; }; I've read about the different type of dns server, like primary master etc. The first two parts (zone and zone) corresponds to primary dns server configuration. First record for "classic" lookup, second one for reverse. The last part (forwarders) is configuration of cache-server and contains the ISP's IP of DNS server. So all names resolved thanks to this server will be cached. Simple question: am I right? Does my description make sense? Or one server can be only either master or either cached?

• OpenWRT + OpenVPN client forwarding from lan to vpn not working

  - by Dariusz Górecki

  I've OpenWRT router with Backfire 10.03.1-rc3 (arch:brcm 2.6 kernel) I've set up an OpenVPN client connecting my router with workplace lan, and it works nicely, I can connect from router to networks (several) in workplace. My OpenVPN client uci-config looks like: config 'openvpn' 'stream_client' option 'nobind' '1' option 'float' '1' option 'client' '1' option 'reneg_sec' '0' option 'management' '127.0.0.1 31194' option 'explicit_exit_notify' '1' option 'verb' '3' option 'persist_tun' '1' option 'persist_key' '1' list 'remote' 'remote.address.cutted' option 'ca' '/lib/uci/upload/cbid.openvpn.stream_client.ca' option 'key' '/lib/uci/upload/cbid.openvpn.stream_client.key' option 'cert' '/lib/uci/upload/cbid.openvpn.stream_client.cert' option 'enable' '1' option 'dev' 'tun1' I've set the 'STREAM_VPN' Zone to allow in/out traffic, and I've added rules for zone-to-zone lan<-vpn and vpn<-lan config 'zone' option 'name' 'stream_vpn' option 'network' 'stream_vpn' option 'input' 'ACCEPT' option 'output' 'ACCEPT' option 'forward' 'REJECT' config 'forwarding' option 'src' 'lan' option 'dest' 'stream_vpn' config 'forwarding' option 'src' 'stream_vpn' option 'dest' 'lan' And interface config: config 'interface' 'stream_vpn' option 'proto' 'none' option 'ifname' 'tun1' option 'defaultroute' '0' option 'peerdns' '0' Now, from my router everything works nicely, the problem is that I cannot connect from computer inside a lan to hosts in networks provided by vpn connection :/ What I've missed, or what I'm doing wrong? And how can I force using specified DNS when connected to vpn? (I know that sever should use PUSH DNS option, but is PUSHes only routes)
