DESCRIPTION
This module implements a server for the Trivial File Transfer Protocol.
From Wikipedia:
Trivial File Transfer Protocol (TFTP) is a file transfer protocol notable
for its simplicity. It is generally used for automated transfer of
configuration or boot files between machines in a local environment.
The connection ($c) which is referred to in this document is an instance of Mojo::TFTPd::Connection.
EVENTS
error
$self->on(error => sub {
my($self, $str) = @_;
});
This event is emitted when something goes wrong: Fail to "listen" to socket, read from socket or other internal errors.
finish
$self->on(finish => sub {
my($self, $c, $error) = @_;
});
This event is emitted when the client finish, either successfully or due to an error. $error
will be an empty string on success.
rrq
$self->on(rrq => sub {
my($self, $c) = @_;
});
This event is emitted when a new read request arrives from a client. The callback should set "filehandle" in Mojo::TFTPd::Connection or the connection will be dropped. "filehandle" in Mojo::TFTPd::Connection can also be a Mojo::Asset reference.
wrq
$self->on(wrq => sub {
my($self, $c) = @_;
});
This event is emitted when a new write request arrives from a client. The callback should set "filehandle" in Mojo::TFTPd::Connection or the connection will be dropped. "filehandle" in Mojo::TFTPd::Connection can also be a Mojo::Asset reference.
ATTRIBUTES
connection_class
$str = $self->connection_class;
$self = $self->connection_class($str);
Used to set a custom connection class. Defaults to Mojo::TFTPd::Connection.
ioloop
Holds an instance of Mojo::IOLoop.
listen
$str = $self->server;
$self->server("127.0.0.1:69");
$self->server("tftp://*:69"); # any interface
The bind address for this server.
max_connections
How many concurrent connections this server can handle. Default to 1000.
retries
How many times the server should try to send ACK or DATA to the client before dropping the connection.
inactive_timeout
How long a connection can stay idle before being dropped. Default is 15 seconds.
retransmit
How many times the server should try to retransmit the last packet on timeout before dropping the connection. Default is 0 (disable retransmits)
retransmit_timeout
How long a connection can stay idle before last packet being retransmitted. Default is 2 seconds.
METHODS
start
Starts listening to the address and port set in "Listen". The "error" event will be emitted if the server fail to start.
