PEER_MSG_FILE

Channel: 0

Sub-packet of PEER_MSG for MSGTYPE 3. This packet is used to initiate/acknowledge a file transfer. It is used only in version 7 of the protocol; for version 8, use PEER_MSG_GREET with an appropriate sub command. Note, however, that some clients claim to do v8 that still use this, including Trillian 0.73.

Parameters

Data type	Content	Name	Description
WORD.B	xx xx	PORT	The port to which the file should be sent. Note this and PORT2 are empty in the request.
WORD	xx xx	PAD	Unknown or padding.
LNTS	xx xx ...	NAME	The file name. This will be empty in the ACK.
DWORD.L	xx xx xx xx	FILELEN	The length of the file in bytes.
DWORD.L	xx xx xx xx	UNKNOWN	If I'd know, I'd be lucky. Looks like a piece of text. New for version 7; for version 6, this is left out.
DWORD.L	xx xx xx xx	PORT2	The port again.
