Net::BitTorrent::Peer(3) User Contributed Perl Documentation Net::BitTorrent::Peer(3)

Net::BitTorrent::Peer - Remote BitTorrent Peer

Net::BitTorrent::Peer represents a single peer connection.

"new ( { [ARGS] } )"
Creates a Net::BitTorrent::Peer object. This constructor should not be used directly.

"bitfield ( )"
Returns a bitfield representing the pieces that have been reported to be successfully downloaded by the remote peer.
"am_choking ( )"
Returns a boolean value based on whether or not we are currently choking the remote peer.
"am_interested ( )"
Returns a boolean value based on whether or not we are currently interested in the set of pieces held by the remote peer
"host ( )"
Returns the host (typically an IP address) of the remote peer.
"incoming ( )"
Returns a boolean value based on whether or not this connection was initiated by the remote peer or us.
"peer_choking ( )"
Returns a boolean value based on whether or not the remote peer is currently choking us.
"peer_interested ( )"
Returns a boolean value based on whether or not the remote peer is currently interested in being unchoked or in requesting data from us.
"peerid ( )"
Returns the Peer ID used to identify this peer.
See also: (
"port ( )"
The port used by the remote peer.
"reserved_bytes ( )"
Returns the 8 reserved bytes from the plaintext handshake. Each bit in these bytes can be used to change the behavior of the protocol.
See also: (
"source ( )"
In a future version, this will return how we obtained this connection (DHT, user, incoming, certain tracker, etc.).
"torrent ( )"
Returns the related Net::BitTorrent::Torrent object. This will be "undef" if the peer has not completed the handshake.
"as_string ( [ VERBOSE ] )"
Returns a 'ready to print' dump of the object's data structure. If called in void context, the structure is printed to "STDERR". "VERBOSE" is a boolean value.

As of version "0.049_8" of this module, "peer_disconnect" callbacks are provided with a language agnostic, numeric reason. So far, this is the list of possible disconnections:
The connection closed by remote peer for unknown reasons
We connected to ourself according to PeerID.
Remote peer attempted to create a session related to a torrent we aren't currently serving. Occasionally, this will also provide an "Infohash" parameter for your callback.
A remote peer sent us a bad plaintext handshake. This is triggered when, after a particular infohash was implied in an encrypted handshake, the remote peer sent us a mismatched infohash in the plaintext handshake.
Bad plaintext handshake. May be malformed or, if encryption is disabled locally, the remote peer attempted an encrypted handshake.
This is given when the remote peer gives us a malformed packet. See also DISCONNECT_MALFORMED_HANDSHAKE.
Already connected to this peer. When there are too many established connections with a particular peer (as determined by their PeerID), we disconnect further connections with the reason. This reason provides the remote peer's "PeerID" when triggered.
Enough peers already! We've hit the hard limit for the number of peers allowed globally or per torrent.
This reason is given when a remote peer connects to us while the torrent they're seeking is busy being hash checked (potentially in another thread).
This is given when we and the remote peer are both seeds.
Peer failed to complete plaintext or encrypted handshake within 30s.
Peer has been connected for at least 3m and is neither interested nor interesting.
Failed to sync MSE handshake at stage five.
To import this list of keywords into your namespace, use the "disconnect" tag. Please note that this API tweak is experimental and may change or be removed in a future version.'s also probably incomplete.
