Tftp is specified by: https://www.rfc-editor.org/rfc/rfc1350.txt To send datagrams to the broadcast address, you need to set SO_BROADCAST in setsockopt(), so unpatched the traditional clients won't work. For details see: man 7 socket man setsockopt Theese might help: https://www.abc.se/~m6695/udp.html https://people.cs.rutgers.edu/~pxk/417/notes/sockets/udp.html https://users.cs.jmu.edu/bernstdh/web/common/lectures/summary_unix_udp.php Regards, /Karl Hammar
