"The Codenomicon tools are amazing. Using them is like being attacked by the most relentless adversary who uses every possible method to find flaws in your code
We fixed subtle crash bugs in Samba that had been in the code for over ten years. We would never have found those bugs without the Codenomicon tools.
If you're serious about implementing protocols correctly, you need the Codenomicon tools."

Codenomicon TFTP Test Tool Data Sheet
- Test tool: Codenomicon TFTP Test Tool
- Direction: Server
Trivial File Transfer Protocol (TFTP) is a simple form of the File Transfer Protocol (FTP). TFTP uses the User Datagram Protocol (UDP) and provides no security features. It is historically used by servers to boot diskless workstations, X-terminals, and routers. Nowadays TFTP is commonly used to update firmware on various embedded devices such as routers and DSL modems. The Codenomicon TFTP Test Tool is a test tool for analysing the implementation-level security and robustness of TFTP server (daemon) implementations.
