Port in a Windows environment

What is a port in windows environment?
Where to configure the ports?

During SCCM 2012 installation two ports have to be enabled.. 1433 & 4022? What are these and where to enable these ports?

What ate inbound rules and what are outbound rules?

Please help me.

Thanks,
Venkat



You configure them in the firewall

Port http://en.wikipedia.org/wiki/Port_%28computer_networking%29

a port is an application-specific or process-specific software construct serving as a communications endpoint in a computer's host operating system. A port is associated with an IP address of the host, as well as the type of protocol used for communication. The purpose of ports is to uniquely identify different applications or processes running on a single computer and thereby enable them to share a single physical connection to a packet-switched network like the Internet.

it basically is a sub address of the computer, so that OS knows which program shoud get the data

The inbound and outbound rules you define in the firewall. You specify which computers (IP, IP ranges, local network...) can communicate with your computer and on which ports (since every software has a default or specified port, you thereby define which software on the computer is accessible from outside (server)- inbound, or can start to communicate to outside (client) - outbound)

Hi,

I just felt this could help you understand better..

Port
Picture a bay where there are lots of private boats are docked. The overall location is called a seaport, literally a port at or on the sea. Everyone wanting to dock thereÑrequesting landing servicesÑuses the same port. Seaports work with berth numbers assigned to individual boats. The port name and the berth number combine into the "who, what, and where" of boat identification.

In geek-speak, berth numbers on the Internet are Internet Protocol or IP addresses, a user's numerical identifier on the Internet. Depending on connection type and service provider, a user's IP address may or may not remain the same with each connection to or "docking" on the Internet.

A computer port is a type of electronic, software- or programming-related docking point through which information flows from a program on your computer or to your computer from the Internet or another computer in a network. (A network, by the way, is a series of computers that are physically or electronically linked.)

In computer terms, a computer or a program connects to somewhere or something else on the Internet via a port. Port numbers and the user's IP address combine into the "who does what" information kept by every Internet Service Provider.

Ports are numbered for consistency and programming. The most commonly used and best known ports are those numbered 0 to 1023 dedicated for Internet use, but they can extend far higher for specialized purposes. Each port set or range is assigned specialized jobs or functions, and that's generally all they do. Usually, all identical system services or functions use the same port numbers on the receiving servers.

What is a firewall?

A firewall is a software program or piece of hardware that helps screen out hackers, viruses, and worms that try to reach your computer over the Internet.

What are Firewall rules?
A security system that uses rules to block or allow connections and data transmission between your computer and the Internet..

What is a Inbound Rule?
Inbound rules explicitly allow, or explicitly block, inbound network traffic that matches the criteria in the rule.

What is a Outbound Rule?
Outbound rules explicitly allow, or explicitly block, network traffic originating from the computer that matches the criteria in the rule.
