tftp-serve - a simple TFTP server

A TFTP server with a simplified user interface. Works like a normal synchronous command line program, does not require a global configuration file.

It takes a list of files to server from stdin in the following format:

<ftpname>:<filepath>

For example:

$ echo 'firmware:./build/firmware.bin' | tftp-serve 192.168.11.1

For more than one file, you can make a wrapper shell script like this:

tftp-serve 192.168.11.1 <<EOF
kernel:os/kernel.img
ramdisk:os/initramfs.img
uboot.bin:u-boot/u-boot.bin
EOF

Run tftp-serve --help to see all awailable options.

Installation

$ stack install

The executable tftp-serve will be installed to ~/.local/bin. You might want to add that path to the environment variable PATH.

The tftp dependency

This source includes a copy of the tftp library from Hackage with the following changes:

• Set SO_REUSEADDR and SO_REUSEPORT on the listening socket
• Fixed minor build problems

The upstream library has not been updated since 2012, so as quick solution I simply copied it and hacked it in-place.
