First, the SSH client uses the transport layer to initiate a connection to the SSH server using port 22. Once the client makes a connection, the server sends its public key back to the client to authenticate the server. In other words, the server is "proving" that it is who it says ...
At SiteGround, the default port number for SSH is18765, deviating from the default port 22 for extra security enhancement. During the course of the key exchange phase, the server identifies itself to the client using ahost key. If you are connecting to that server for the first time, the ...
SSH also allows for tunneling, or port forwarding, which is when data packets are able to cross networks that they would not otherwise be able to cross. SSH is often used for controlling servers remotely, for managing infrastructure, and for transferring files. When traveling, the owner of a...
When local port forwarding is used, OpenSSH creates a separate tunnel inside the SSH connection that forwards network traffic from the local port to the remote server's port. In OpenSSH, this tunneling feature can be used by supplying-Lflag. Internally, SSH allocates a socket listener on the...

A network port is a virtual point of connection on a computer or network device, used to identify specific processes or types of network services. Each port is associated with a number, ranging from 0 to 65535, known as aport number. These numbers help direct data to the correct application...
an extension of Secure Shell (SSH). It was introduced in SSH v2 or SSH-2 as a method for transferring files. Since SFTP runs over SSH, every SSH server is technically an SFTP server as well. In addition, since SSH listens on port 22 by default, SFTP listens on that port number too...
Port 22 is generally used for connection via SSH. SFTP is just one of protocols which can be run over SSH (others include virtual terminal). In fact, the SFTP is independent and can be run even without using SSH. SFTP is sometimes called "Secure FTP" which leads to a common confusion ...
Port 22: Secure Shell (SSH). SSH is one of many tunneling protocols that create secure network connections. Port 25: Historically, Simple Mail Transfer Protocol (SMTP). SMTP is used for email. Port 53: Domain Name System (DNS). DNS is an essential process for the modern Internet; it mat...
This is the start page for the SSH (Secure Shell) protocol, software, and related information. SSH is a software package that enables secure system administration and file transfers over insecure networks. It is used in nearly every data center and in every large enterprise. ...
