This document applies to all versions of Horizon 7 from 7. Figure 1 shows three different client connection types and also includes all display protocols.

Below, we take a look at these protocols, provides a basic description of their function, and lists the port numbers that they are commonly associated with. FTP is one of the most commonly used file transfer protocols on the Internet and within private networks.

List of TCP and UDP port numbers

A network object is identified by a protocol address. When a connection is made, the client and the receiver of the request listener , Oracle Connection Manager , or Oracle Names server are configured with identical protocol addresses. The client uses this address to send the connection request to a particular network object location, and the recipient "listens" for requests on this address, and grants a connection based on its address information matching the client information.

The listener, Oracle Names server and Oracle Connection Manager are identified by protocol addresses. Specify a unique name for the service. Specify the pipe name you used to connect to the database server the same PIPE keyword you specified on server with Named Pipes. This name can be any arbitrary name. See Also: "Recommended Port Numbers".

Default listening port for client connections to the listener. Default and officially registered listening port for client connections to Oracle Connection Manager. Default and officially registered listening port for administrative commands to Oracle Connection Manager. Oracle Corporation allows port numbers from 1 to Port numbers less than are reserved for use by privileged processes on many operating systems.

On certain operating systems, only privileged processes can listen for TCP connections on ports less than If you need to configure listener to listen on a port number less than , follow these general steps. Your operating system may require different procedures. Oracle9i Net Services Administrator's Guide. Ensure that the permissions of the individual directories found in the path names to these files, starting with the root directory, are also modified in the same way. At the operating system prompt, enter tnslsnr with optional command line arguments.

The usage is as follows:. Specify the name of the listener. Specify the user whose privileges the listener will use when super user root privileges are not needed. After performing the privileged operations, the listener will give up root privileges irreversibly. Specify the group whose privileges the listener will use when super user root group privileges are not needed.

After performing the privileged operations, the listener will give up root group privileges irreversibly. The listener will temporarily switch to the provided user and group immediately after startup. All subsequent operations will be done with the specified user and group privileges, except the system calls necessary to listen on configured endpoints. The listener will revert to super user root for a short period of time to listen on reserved addresses, such as TCP ports less than After the listener starts listening on all of its endpoints configured in listener.

Therefore, the listener will give up the root privilege that it initially had. In the current release, -user and -group command line arguments only accept user and group identifiers specified in numeric form. For example, to execute a root listener called mylsnr and have it use privileges of a user identified as with a group identifier of 16, enter the following at the operating system command prompt.

Note that could be the identifier for user oracle and 16 could be the identifier for the dba group. See Also : "Protocol Parameters" for each protocol's required parameters. Important Notes: Oracle Corporation recommends that the user under which the listener process runs be oracle , as described in the example in Step 3, or whichever user the listener process normally runs as on the operating system.

Do not leave the listener process running as root because doing so is a security vulnerability. All Rights Reserved. Book List. Specify the name of the Oracle server computer. Specify the host name or IP address of the computer.

Specify the listening port number. Specify tcps as the value. Master Index.

Service Name and Transport Protocol Port Number Registry

Jump to navigation. The physical ports on your computer allow communicate with peripheral devices such as your keyboard and mouse and to connect with internet devices via Ethernet cables. When a computer system seeks to connect to another computer, the port serves as a communication endpoint. In simple terms, if a software application or service needs to communicate with others, it will expose a port. Ports are identified with positive bit unsigned integers, ranging from 0 to Other services use this port number to communicate with the service or app.

Similarly many of the official assignments refer to protocols that were never or are no longer in common use. This article lists port numbers and their associated protocols that have experienced significant uptake. On Unix-like operating systems, a process must execute with superuser privileges to be able to bind a network socket to an IP address using one of the well-known ports. They are assigned by IANA for specific service upon application by a requesting entity. From Wikipedia, the free encyclopedia.

Service Name and Transport Protocol Port Number Registry

For example, port 80 is used by web servers. Port to These are ports that an organization, such as application developers, can register with IAMA to be used for a particular service. These should be treated as semi-reserved. Port to These are port numbers used by client programs, such as a web browser.

A network object is identified by a protocol address. When a connection is made, the client and the receiver of the request listener , Oracle Connection Manager , or Oracle Names server are configured with identical protocol addresses. The client uses this address to send the connection request to a particular network object location, and the recipient "listens" for requests on this address, and grants a connection based on its address information matching the client information.

Но решил этого не делать. Сьюзан так и подумала. Старшие должностные лица АНБ имели право разбираться со своими кризисными ситуациями, не уведомляя об этом исполнительную власть страны. АНБ было единственной разведывательной организацией США, освобожденной от обязанности отчитываться перед федеральным правительством. Стратмор нередко пользовался этой привилегией: он предпочитал творить свое волшебство в уединении.

 - Танкадо обманул всех. По его тону ей стало ясно, что он все понял. Вся ложь Танкадо о невскрываемом алгоритме… обещание выставить его на аукцион - все это было игрой, мистификацией. Танкадо спровоцировал АНБ на отслеживание его электронной почты, заставил поверить, что у него есть партнер, заставил скачать очень опасный файл.

Фонтейну нужен был кто-то способный наблюдать за Стратмором, следить, чтобы он не потерял почву под ногами и оставался абсолютно надежным, но это было не так-то. Стратмор - человек гордый и властный, наблюдение за ним следует организовать так, чтобы никоим образом не подорвать его авторитета. Из уважения к Стратмору Фонтейн решил заняться этим лично.
