The number of retries left before aborting the transmission. This number will be reset to the AnyEvent::TFTPd::retries manpage each time last_seen_peer is updated.

METHODS

This method will send a packet of data from filehandle to client, identified by peername. The packet is calculated using the MIN_BLKSIZE and packet_number. Returns 1 on success, 2 if this is the last packet to be sent, 0 if something went wrong and -1 if no more data is available from filehandle.

receive_ack

This method will receive a datagram and unwraps the packet number from it using unpack("n"). It will increase the packet_number if the received packet number matches packet_number.

Will always call send_packet and return the value it returns. A return value of -1 indicates that the last ACK was received and the connection can be "shut down".

receive_packet

This method will receive a datagram and unwraps the packet number and body from it using unpack("na*"). It stores the data in the current filehandle if the packet number equals packet_number. It returns 1 on success, 0 on failure and -1 if this was the last packet to be received. The latter indicates that it is safe for this connection to "shut down".

send_ack

This method is called inside receive_packet() and is used to tell the peer that a packet is received.

send_error

Takes a "name" indicating a type of error, which is looked up from the %ERROR_CODES variable (see the source for details). Falls back to "not_defined", if an invalid name was passed on. Packs the data from %ERROR_CODES and pass it to the remote client. Returns 1 on success and 1 on failure.

logf

 $self->logf($level => @message);

Receives a $level and a list of strings, suitable for printf(): The first element in @message is a format and the rest (if exists) will be the replacement for %s and friends in the format. The level has the same name as defined for the Log::Log4perl manpage.
