Interactive client for the Trivial File Transfer Protocol (TFTP). Its usage is mainly for testing and debugging the atftp server. A TFTP client is usually implemented in UEFI/BIOS and bootstrap programs like pxelinux when booting from LAN. The atftp client also supports non-interactive invocation for easy use in scripts.

Only use this tool against systems you own or are explicitly authorized to test — see the disclaimer.
