tftpd-cgi

A simple tftp server implementation capable of serving CGI scripts from a specified cgi directory (defaults to cgi/).

This would be useful for serving different boot configurations for PXE based on IP or MAC address.

Configuration is currently done at the top of tftpd-cgi.py.

TODO

• The WRITE/put operation
• Command-line args
• CGI timeout
• Proper error handling. Use the messages and codes defined at the end of RFC 1350

Usage

Simply run python tftpd-cgi or ./tftpd-cgi.py to start the server. Remember you usually need elevated privileges to bind to ports under 1024, and TFTP uses port 69 by default.

This ships with a basic cgi script: "cgi/test". It currently outputs a simple message and the client HOST:PORT when retrieved.

With a simple tftp client, I test the cgi functionality like this:

echo 'get cgi/test' | tftp 127.0.0.1; cat test && rm test
