Dsl Provider Driver



The best DSL providers and plans will usually be in suburban areas, where you have a stronger likelihood of being close to the provider office or “DSLAM” that connects to the Internet at large. In rural areas, subscribers often get slower speeds in the 1–5 Mbps range due to signal degradation over long distances. Right click the adapter and then click Update Driver Software. Click Browse my computer for driver software. Click let me pick from a list of device drivers on my computer and click Next. Highlight Show compatible hardware and click Have Disk. Click Browse and Open the inf file that you have already downloaded and extracted.

Applies to:SQL Server (all supported versions) Azure SQL Managed Instance

Linked servers enable the SQL Server Database Engine and Azure SQL Managed Instance to read data from the remote data sources and execute commands against the remote database servers (for example, OLE DB data sources) outside of the instance of SQL Server. Typically linked servers are configured to enable the Database Engine to execute a Transact-SQL statement that includes tables in another instance of SQL Server, or another database product such as Oracle. Many types OLE DB data sources can be configured as linked servers, including Microsoft Access, Excel, and Azure CosmosDB.

Note

Linked servers are available in SQL Server Database Engine and Azure SQL Managed Instance. they are not enabled in Azure SQL Database Singleton and Elastic pools. There are some constraints in Managed Instance that can be found here.

When to use Linked Servers?

Linked servers enable you to implement distributed databases that can fetch and update data in other databases. They are a good solution in the scenarios where you need to implement database sharding without need to create a custom application code or directly load from remote data sources. Linked servers offer the following advantages:

  • The ability to access data from outside of SQL Server.

  • The ability to issue distributed queries, updates, commands, and transactions on heterogeneous data sources across the enterprise.

  • The ability to address diverse data sources similarly.

You can configure a linked server by using SQL Server Management Studio or by using the sp_addlinkedserver (Transact-SQL) statement. OLE DB providers vary greatly in the type and number of parameters required. For example some providers require you to provide a security context for the connection using sp_addlinkedsrvlogin (Transact-SQL). Some OLE DB providers allow SQL Server to update data on the OLE DB source. Others provide only read-only data access. For information about each OLE DB provider, consult documentation for that OLE DB provider.

Linked Server Components

Doma Driver download. A linked server definition specifies the following objects:

  • An OLE DB provider

  • An OLE DB data source

An OLE DB provider is a DLL that manages and interacts with a specific data source. An OLE DB data source Fujitsu network & wireless cards driver download for windows 7. identifies the specific database that can be accessed through OLE DB. Although data sources queried through linked server definitions are ordinarily databases, OLE DB providers exist for a variety of files and file formats. These include text files, spreadsheet data, and the results of full-text content searches.

Starting with SQL Server 2019 (15.x), the Microsoft OLE DB Driver for SQL Server (MSOLEDBSQL) (PROGID: MSOLEDBSQL) is the default OLE DB provider.In earlier versions, the SQL Server Native Client OLE DB provider (SQLNCLI) (PROGID: SQLNCLI11) was the default OLE DB provider.

Note

SQL Server distributed queries are designed to work with any OLE DB provider that implements the required OLE DB interfaces. However, SQL Server has been tested against the default OLE DB provider.

Linked Server Details

The following illustration shows the basics of a linked server configuration.

Provider

Typically, linked servers are used to handle distributed queries. When a client application executes a distributed query through a linked server, SQL Server parses the command and sends requests to OLE DB. The rowset request may be in the form of executing a query against the provider or opening a base table from the provider.

Note

For a data source to return data through a linked server, the OLE DB provider (DLL) for that data source must be present on the same server as the instance of SQL Server.

Important

When an OLE DB provider is used, the account under which the SQL Server service runs must have read and execute permissions for the directory, and all subdirectories, in which the provider is installed. This includes Microsoft-released providers, and any third-party providers.

Note

Linked servers support Active Directory pass-through authentication when using full delegation. Starting with SQL Server 2017 (14.x) CU17, pass-through authentication with constrained delegation is also supported; however, resource-based constrained delegation is not supported.

Managing Providers

There is a set of options that control how SQL Server loads and uses OLE DB providers that are specified in the registry.

Managing Linked Server Definitions

When you are setting up a linked server, register the connection information and data source information with SQL Server. After being registered, that data source can be referred to with a single logical name.

You can use stored procedures and catalog views to manage linked server definitions:

  • Create a linked server definition by running sp_addlinkedserver.

  • View information about the linked servers defined in a specific instance of SQL Server by running a query against the sys.servers system catalog views.

  • Delete a linked server definition by running sp_dropserver. You can also use this stored procedure to remove a remote server.

You can also define linked servers by using SQL Server Management Studio. Disc soft driver download for windows 10. In the Object Explorer, right-click Server Objects, select New, and select Linked Server. You can delete a linked server definition by right-clicking the linked server name and selecting Delete.

When you execute a distributed query against a linked server, include a fully qualified, four-part table name for each data source to query. This four-part name should be in the form linked_server_name.catalog.schema.object_name.

Note

Linked servers can be defined to point back (loop back) to the server on which they are defined. Loopback servers are most useful when testing an application that uses distributed queries on a single server network. Loopback linked servers are intended for testing and are not supported for many operations, such as distributed transactions.

Web Supplement: Drivers for Broadband Modems
by Rod Smith,rodsmith@rodsbooks.com


As noted in my book, Broadband InternetConnections, drivers for broadband modems aren't always easy tocome by, especially for Linux or less popular OSs. As a general rule,the safest course of action is to use an external Ethernet-interfacedmodem. These are the most common type of cable modem, although manycable modems introduced in 2001 include both Ethernet and USBinterfaces. (The USB interfaces are usually reputed to be moretrouble-prone than the Ethernet interfaces, even when used underWindows.) DSL modems more commonly come in internal or USB-interfacedform, and some DSL ISPs provide only one of these modem types.

Dsl Provider Driver

Increasingly, you can find broadband modems (especially cablemodems) for sale at local retailers like CompUSA,Fry's Electronics, or Circuit City. Online retailers,such as TC Computers,Comp-U-Plus, and Outpost.com, also carry broadbandmodems. A few manufacturers, such as ZyXEL and Westell, sell their products directto consumers. You can also often find good deals on used equipment onauction sites like eBay. Wherever youbuy, make sure the device you purchase is compatible with yourprovider's equipment, as described in my book. In particular, check thata cable modem is DOCSIS compliant, or uses whatever protocol your cablecompany uses rather than DOCSIS; and check that a DSL modem is of thecorrect type (ADSL, SDSL, and so on) and sub-type (DMT or CAP ADSL, forinstance). If possible, buy a modem that's on your ISP's list ofsupported equipment, to avoid finger-pointing about the cause of anyproblems you might experience.

Internal DSL Modems

Internal DSL modems are network cards that 'speak' the low-level DSLprotocols directly. This type of hardware, like any hardware, requiresdrivers in order to function. Unfortunately, at the moment, non-Windowsdrivers for internal DSL modems are virtually nonexistent. Therefore,if you're not using Windows, chances are you'll need to acquire anexternal DSL modem which connects to the computer via an Ethernetline.

I have heard of several internal DSL modems with Linux drivers:

  • The Diamond 1MM internal. This board apparently uses an SMC chipset, and it works with a modified epic100.c driver. (The preceding URL seems to be broken, as of 8/3/2001; here's another one.) The comments in the source code indicate that you must compile the modified driver as a module and load it with the options=1 option. Note that I have not tried this procedure, because I don't own the requisite hardware. Therefore, the only advice I can offer is to read the comments at the start of the source code. Also, this driver is for a 2.2.9 kernel, and so may not work with more recent kernels.
  • The Sangoma S518 PCI card. Linux drivers are supposedly available, but I can't seem to find the card or driver on Sangoma's Web site, as of 6/24/02. David Mandelstam (dm@sangoma.com) at Sangoma tells me the driver is available, and the card should be out in August of 2002. The driver apparently includes some third-party non-GPL code, and so source code isn't available; but David claimed Sangoma can compile it for 'any kernel.'
  • The Dynalink AHL110 PCI board. The Web page includes a pre-patched 2.2.12 kernel and dirvers for 2.2.12 and 2.4.2 kernels, as of 6/24/02. I don't have one of these cards and so can't comment on how well the drivers work. Apparently this card is based on an Itex chipset, so it's conceivable the drivers will work with other boards.
  • The Xpeed X-200 and Xpeed X-300. Again, I don't have these boards and so can't comment on how well the drivers work. (In fact, as of 6/24/02, there appear to be DNS problems with the xpeed.com domain, so I can't even check that the drivers are really there.)

If you hear of any internal DSL modem that's supported by anynon-Windows OS, please drop mea line with the information, and I'll mention it here.

USB DSL Modems

Like internal DSL modems, USB DSL modems require special drivers tofunction. An OS's basic USB drivers are not sufficient; theseprovide only the ability to talk to USB devices generically, not tohandle specific devices such as USB modems. You will need a driver foryour specific model of modem.

As of June of 2002, I know of only three USB DSL modems for whichnon-Windows drivers exist:

  • The Thomson (formerly Alcatel) Speed Touch USB. You must obtain the drivers from Thomson/Alcatel, which provides support for Windows, MacOS Classic, MacOS X, and Linux. As with internal DSL modems, I have no experience with the Alcatel SpeedTouch USB, so I can't comment on the quality of these drivers from personal experience. I have heard, however, that the 1.3.4 drivers for Linux are configured to compile with 686 optimizations by default, and the only way to change this is to manually edit the configuration script. Even doing that won't fix the binary-only support programs, so these drivers won't really work in Linux on anything less than a Pentium Pro.
  • The Allied Telesyn AR-215 DMT ADSL modem and similar Allied Telesys AR-210 G.Lite modem. I don't have one of these modems, and so can't comment on the quality of the Linux drivers (also read the documentation, which is in Microsoft Word format, but loads reasonably well in OpenOffice.org). The drivers are supposed to work with Red Hat 7.2 and its 2.4.7-10 kernel. These modems are apparently based on an Analog Devices chipset. In fact, the drivers appear to originate with Analog Devices. Allied Telesyn doesn't yet officially support the drivers, although they did send them to me. Note: Allied Telesyn sent me updated drivers on 7/18/02. If you downloaded the driver file before then, you might want to try the new one.
  • The Aus.Linx AL-2006. This modem apparently uses a Conexant chipset. Once again, I don't have one of these modems and can't promise that the drivers work, but Linux drivers are available for the product.

If you have some other USB DSL modem, you can try asking themanufacturer for drivers, or check the Linux USB Web site for informationon Linux driver developments. If you have no luck, you may need to buyan Ethernet-interfaced DSL modem and sell the USB model to recover mostof the cost.

If you hear of any USB DSL modem that's supported by any non-WindowsOS, please drop me a linewith the information, and I'll mention it here.

Internal and USB Cable Modems

Internal cable modems are extremely rare, although there are a fewmodels available. I know of only one non-Windows driver for such adevice: The Linux kernel includes support for the General InstrumentsSurfboard 1000, an old one-way cable modem. Because this driver is partof the Linux kernel, you should check your kernel and moduleconfiguration to see if the driver is available on your system. If it'snot, you'll have to recompile your kernel, or at least that onemodule.

As noted earlier, many cable modems introduced in 2001 include bothEthernet and USB interfaces, but there are few USB-only devices. Evenin Windows, for which USB drivers for dual-interface devices are mostcommon, it's best to use the Ethernet interface, which tends to be lessfinicky than the USB interface.
