++ As stated in ++ (RFC 1350) ++ be aware that "Since TFTP includes no login or access control mechanisms, ++ care must be taken in the rights granted to a TFTP server process so as ++ not to violate the security of the server hosts file system. ++ TFTP is often installed with controls such that only files that have ++ public read access are available via TFTP and writing files via TFTP ++ is disallowed." ++

++

++ This essentially means that any machine on the network ++ that can reach the TFTP server is able to read and write, ++ without authentication, any file on the machine that runs ++ the TFTP server, that the user (or group) that runs the TFTP server ++ (in this case the Erlang VM) is allowed to read or write. ++ The machine configuration has to be prepared for that. ++

++ ++

++ The default behavior mentioned above is in general very risky, ++ and as a remedy, this TFTP application's default callback ++ tftp_file implements an initial state option ++ {root_dir,Dir} that restricts the callback's file accesses ++ to Dir and subdirectories.
