FMTapp

P2P file share module with centralized server for tracking files, supports custom ui

It follows simple protocol:

• When a peer A connects to FMT, A should automatically send information about its shared files as a list of records to the FMT in the following format: <file name, file type (text, jpg, etc), file size, file last modified date (DD/MM/YY), IP address, port number>. A should send “HELLO” and receive “HI” before sending the information.

• When A wants to download a file with the name “File Name”, A requests the file from FMT by sending “SEARCH: ” + “File Name”. FMT finds records that exactly match (or partially match) “File Name”. FMT should send “FOUND: ” + list of records if it finds, or “NOT FOUND” if it finds no records.

• After receiving a list of records, A should choose one of the peers2 from the list, say B, and connect to B (using IP and port number) to request and download the file. For that A should send “DOWNLOAD: ” + “FileName”

• When A wants to leave the system, A should notify FailMailTracker about this so that FMT can remove A from the list of online users. A should send “BYE” to MT to do so.
