UDP 119

Looking for information on Protocol UDP 119? This page will attempt to provide you with as much port information as possible on UDP Port 119.

UDP Port 119 may use a defined protocol to communicate depending on the application. A protocol is a set of formalized rules that explains how data is communicated over a network. Think of it as the language spoken between computers to help them communicate more efficiently.

Protocol HTTP for example defines the format for communication between internet browsers and web sites. Another example is the IMAP protocol that defines the communication between IMAP email servers and clients or finally, the SSL protocol which states the format to use for encrypted communications.

PORT 119 – Information

• Port Number: 119
• TCP / UDP: UDP
• Delivery: No
• Protocol / Name: nntp
• Port Description: Network News Transfer Protocol.Usenet server feeds (uucp can be used for this too). If used, config nntp server with ACL to control client access. If config’d to allow non-admins to create new newsgroups, host is vulnerable to command meta-character attacks (eg: ";"). nntp messages are simple ascii — susceptable to capture, modification, & forgery. If an nntp server is not hosted at site, ensure it is blocked at firewall. If a server exists and firewall hole is required, proxy server in the DMZ and disable the automated group creation feature. Note that nntp servers can be established in a split-server mode similar to DNS. For outbound nntp to external nntp servers (eg: Internet Usenet), primary threat is download and execution of malicious code.
• Virus / Trojan: No

Side note: UDP port 119 uses the Datagram Protocol, a communications protocol for the Internet network layer, transport layer, and session layer. This protocol when used over PORT 119 makes possible the transmission of a datagram message from one computer to an application running in another computer. Like TCP (Transmission Control Protocol), UDP is used with IP (the Internet Protocol) but unlike TCP on Port 119, UDP Port 119 is connectionless and does not guarantee reliable communication; it’s up to the application that received the message on Port 119 to process any errors and verify correct delivery.

Because protocol UDP port 119 was flagged as a virus (colored red) does not mean that a virus is using port 119, but that a Trojan or Virus has used this port in the past to communicate.
