What is TFTP and how it works?
Trivial File Transfer Protocol (TFTP) is a simple protocol for exchanging files between two TCP/IP machines. TFTP servers allow connections from a TFTP Client for sending and receiving files. The TFTP Server can also be used to upload HTML pages onto the HTTP Server or to download log files to a remote PC.

Which is TFTP server does atftpd run on?
atftpd is a TFTP (RFC1350) server. By default it is started by inetd on most sytems, but may run as a stand alone daemon. This server is multi-threaded and supports all options described in RFC2347 (option extension), RFC2348 (blksize), RFC2349 (tsize and timeout) and RFC2090 (multicast option).
When to write PID to specified file in atftpd?
Write the PID of the server to the specified file. This may be useful when automatically starting and stopping one or more instance of the server. Run as a daemon. Do not use this option if atftpd is started by inetd. When –daemon is specified, this option will prevent the server from forking to background.
How does the atftpd server replace a file name?
The atftpd server provides a way to dynamically replace requested file name by a new one based on Perl compatible regular expression. Pairs of pattern/replacement are read from the specified files. Upon reception of a read request, the server will first try to open the file name requested.
When to specify IP address for atftpd daemon?
Specify the IP address which atftpd binds to. Useful when –daemon is specified. Default is to bind to all interfaces. Only one address can be specified, the server can only listen to one or all interfaces. Specify the TTL to be used for multicast datagram.
