This is tftp-hpa, a conglomerate of a number of versions of the BSD TFTP code, changed around to port to a whole collection of operating systems. The goal is to work on any reasonably modern Unix with sockets. The tftp-hpa series is maintained by H. Peter Anvin . The latest version of this collection can be found at: ftp://ftp.kernel.org/pub/software/network/tftp/ See the file CHANGES for a list of changes between versions. Please see the INSTALL and INSTALL.tftp files for compilation and installation instructions. ===> IMPORTANT: IF YOU ARE UPGRADING FROM ANOTHER TFTP SERVER, OR FROM ===> A VERSION OF TFTP-HPA OLDER THAN 0.17 SEE THE FILE ===> "README.security" FOR IMPORTANT SECURITY MODEL CHANGES! This software can be discussed on the SYSLINUX mailing list. To subscribe, send a message containing the word "subscribe" in the body to . Please note that my main focus in this work is the tftpd server. Although a tftp client is included, it is by and large the stock OpenBSD version, with a small handful of portability improvements.
