Explain RHost, LHost, and Port.
I'm a complete beginner who wants to learn pen testing. I'm having trouble understanding these 3 specific IP's: the remote host, local host, and PORTS.
In my own understanding the remote host is the target's IP address and the local host is your IP address but if your target is outside of your network you will use your public IP address and if your target is inside in your network you will use the local IP right?
But I don't understand what PORTS are.
In many YouTube tutorials they are just inputting "6666", "4444". Can someone explain to me what is the use and where can I find what my PORT is?
The .rhosts File The .rhosts file is the user equivalent of the /etc/hosts.equiv file. It contains a list of host-user combinations, rather than hosts in general. If a host-user combination is listed in this file, the specified user is granted permission to log in remotely from the specified host without having to supply a password.
Note that a .rhosts file must reside at the top level of a user's home directory. .rhost files located in subdirectories are not consulted.
Users can create .rhosts files in their home directories. Using the .rhosts file is another way to allow trusted access between their own accounts on different systems without using the /etc/hosts.equiv file. LHOST is simply Metasploit's way of saying "My localhost as it will be visible by the target of the attack". This may be different whether you and your target are on the same private net (will be a local net address) or are connecting through the internet (will be a public IP) A port is a virtual point where network connections start and end. ... Ports allow computers to easily differentiate between different kinds of traffic: emails go to a different port than webpages, for instance, even though both reach a computer over the same Internet connection.

In the context of networking and systems administration, terms like RHost, LHost, and Port refer to specific elements used in network communication and configuration. Here’s what each term generally refers to:
RHost (Remote Host):
Definition: RHost typically refers to the remote host or remote machine in a network communication scenario. It represents the destination system or device that you want to connect to or interact with over a network.
Usage: When configuring network settings or performing network operations (such as establishing a connection, transferring data, etc.), you specify the RHost to indicate where the communication should be directed. This can be specified using an IP address or a domain name.
LHost (Local Host):
Definition: LHost refers to the local host or local machine in a network context. It represents the system or device from which the communication originates or where the communication is being initiated.
Usage: LHost is used to specify the origin or starting point of a network connection or operation. It is often configured to bind services or applications to a specific network interface or IP address on the local machine.
Port:
Definition: A port is a logical construct used by networking protocols to identify specific endpoints or channels for network communication. Ports are associated with IP addresses on a host and help in directing incoming and outgoing network packets to the appropriate application or service running on that host.
Usage: Ports are numbered from 0 to 65535 and are used to distinguish different services or applications running on a single host. For example, HTTP typically uses port 80, HTTPS uses port 443, FTP uses ports 20 and 21, etc. When configuring network applications or setting up firewalls, you often specify ports to allow or restrict access to specific services.
Practical Example:
Suppose you want to connect to a remote server (RHost) from your local machine (LHost) using SSH (which typically uses port 22):
RHost: The IP address or domain name of the server you want to connect to.
LHost: Your local machine's IP address from where you initiate the SSH connection.
Port: Port 22, which is the standard port for SSH.
Summary:
RHost (Remote Host): Destination system or device in network communication.
LHost (Local Host): Originating system or device in network communication.
Port: Endpoint or channel through which network communication is directed to specific services or applications on a host.
Understanding these terms helps in configuring network settings, troubleshooting network issues, and securing network communications effectively.
