A designated place for educational and training docs, materials and exercises. Also a place to track issues and progress and a lab for code that can be potentially used elsewere.
FTP (File Transfer Protocol) typically uses the following ports:
Port 21: This is the default port used for FTP commands and control.
Port 20: This port is used for FTP data transfer in active mode.
In passive mode, which is often used to get around firewall issues, the FTP server opens a random high port for data transfer, and the client connects to this port.
Telnet typically uses the following port:
Port 23: This is the default port for Telnet connections.
Telnet is an older protocol used for remote communication and accessing devices, but it's not secure because it transmits data, including passwords, in plaintext. For secure remote access, SSH is generally preferred.
SMTP (Simple Mail Transfer Protocol) commonly uses the following ports:
Port 25: This is the default port for SMTP, used for sending emails between servers.
Port 587: This port is used for submitting emails securely from clients to servers using STARTTLS encryption.
Port 465: Historically used for SMTP over SSL/TLS, but it is less commonly used now in favor of port 587 with STARTTLS.
Port 587 is recommended for client-to-server email submissions due to its support for encryption and authentication.
DNS (Domain Name System) typically uses the following ports:
Port 53: This is the default port for DNS queries and responses. DNS can operate over both TCP and UDP on this port.
UDP Port 53: Used for standard DNS queries because it is faster for the majority of DNS transactions.
TCP Port 53: Used for DNS zone transfers and when the response data size exceeds 512 bytes, or for reliability reasons.
DHCP (Dynamic Host Configuration Protocol) uses the following ports:
Port 67: Used by the DHCP server to listen for client requests.
Port 68: Used by the DHCP client to listen for server responses.
DHCP facilitates automatic IP address assignment and other network configuration settings to devices on a network.
TFTP (Trivial File Transfer Protocol) typically uses the following port:
Port 69: This is the default port for TFTP operations.
TFTP is a simplified version of FTP and is used for transferring files with minimal overhead, often in scenarios like network booting or firmware updates. It does not provide security features like encryption.
HTTP (Hypertext Transfer Protocol) commonly uses the following port:
Port 80: This is the default port for HTTP traffic.
HTTP is used for transmitting web pages and other resources over the internet. For secure communications, HTTPS (HTTP Secure) uses port 443.
POP3 (Post Office Protocol version 3) uses the following port:
Port 110: This is the default port for POP3 connections.
POP3 is used for retrieving emails from a mail server. For secure connections, POP3 over SSL/TLS uses port 995.
HTTPS (Hypertext Transfer Protocol Secure) uses the following port:
Port 443: This is the default port for HTTPS traffic.
HTTPS is the secure version of HTTP, encrypting data exchanged between a web server and a client to provide confidentiality and integrity.
IMAP (Internet Message Access Protocol) typically uses the following ports:
Port 143: This is the default port for IMAP connections.
Port 993: Used for IMAP over SSL/TLS, providing a secure connection.
IMAP allows email clients to access and manage email messages on a mail server.
SSH (Secure Shell) uses the following port:
Port 22: This is the default port for SSH connections, which provides secure access to a remote server.
You can use SSH to securely connect to remote machines, transfer files, and execute commands over an encrypted connection.
