File transfer protocols (FTP) use various ports for transferring files. Here are some commonly used file transfer ports and their associated protocols:
- Port 20: FTP Data – This port is used for FTP (File Transfer Protocol) data transfer. It is responsible for transferring the actual files.
- Port 21: FTP Control – The FTP control port is used for sending commands and controlling FTP sessions.
- Port 22: SSH (Secure Shell) – While not exclusively for file transfer, SSH is a secure protocol that can be used for secure file transfers via SFTP (SSH File Transfer Protocol) or SCP (Secure Copy Protocol).
- Port 69: TFTP (Trivial File Transfer Protocol) – TFTP is a simple protocol for transferring files, often used for network device configuration.
- Port 115: SFTP (Simple File Transfer Protocol) – This is a less common file transfer protocol, often used in Unix-like systems.
- Port 989: FTPS Data – FTPS (FTP Secure) is a secure variant of FTP. Port 989 is used for the data transfer in FTPS.
- Port 990: FTPS Control – FTPS control port is used for commands and control in secure FTPS sessions.
- Port 1024-49151: IANA-Registered Ports – Various file transfer protocols and services may use ports in this range for file transfers or related services. These ports can be customized for specific applications.
- Port 514: Syslog – While not a file transfer protocol, it’s used for collecting and forwarding log messages, which can include log files.
- Port 8999: TFTP Alternate – An alternative port for TFTP.
- Port 873: Rsync – Used for remote file synchronization and transfer with the rsync protocol.
These ports play a crucial role in transferring files over a network securely and efficiently. Depending on your specific needs and the protocols you’re using, you’ll use different ports for file transfer operations.
