What can i do with udp over port 69?


Asked by Kalel Barnett on Dec 13, 2021 FAQ



This protocol when used over PORT 69 makes possible the transmission of a datagram message from one computer to an application running in another computer.
Additionally,
Like TCP (Transmission Control Protocol), UDP is used with IP (the Internet Protocol) but unlike TCP on Port 69, UDP Port 69 is connectionless and does not guarantee reliable communication; it’s up to the application that received the message on Port 69 to process any errors and verify correct delivery.
In addition, UDP Port 69 refers to Trivial File Transfer Protocol (TFTP), a file transfer protocol (FTP), implemented on User Datagram Protocol (UDP), that uses a very small amount of memory, so it was used to boot hardware devices that had no real data storage devices (fixed disk/hard drives).
Similarly,
There is no implementation of TFTP using TCP port 69 that I know of. Specifying both UDP and TCP for TFTP in your ACL doesn't make a big difference if you only block a couple of protocols but could easily become a nightmare as your ACL grows. 11-01-2005 02:12 AM
One may also ask,
Because protocol UDP port 69 was flagged as a virus (colored red) does not mean that a virus is using port 69, but that a Trojan or Virus has used this port in the past to communicate. We do our best to provide you with accurate information on PORT 69 and work hard to keep our database up to date.
