Detailed Interface

Events

udp_contents

Type:event (u: connection, is_orig: bool, contents: string)

Generated for UDP packets to pass on their payload. As the number of UDP packets can be very large, this event is normally raised only for those on ports configured in udp_content_delivery_ports_orig (for packets sent by the flow’s originator) or udp_content_delivery_ports_resp (for packets sent by the flow’s responder). However, delivery can be enabled for all UDP request and reply packets by setting udp_content_deliver_all_orig or udp_content_deliver_all_resp, respectively. Note that this event is also raised for all matching UDP packets, including empty ones.

U:The connection record for the corresponding UDP flow. Is_orig:True if the event is raised for the originator side. Contents:TODO.

udp_reply

Type:event (u: connection)

Generated for each packet sent by a UDP flow’s responder. This a potentially expensive event due to the volume of UDP traffic and should be used with care.

U:The connection record for the corresponding UDP flow.

udp_request

Type:event (u: connection)

Generated for each packet sent by a UDP flow’s originator. This a potentially expensive event due to the volume of UDP traffic and should be used with care.

U:The connection record for the corresponding UDP flow.
