$ nncp-ack [options] -all $ nncp-ack [options] -node NODE[,...] $ nncp-ack [options] -node NODE -pkt PKT $ nncp-ack [...] 4>&1 >&2 | nncp-rm [...] -pkt
Send acknowledgement of successful PKT
(Base32-encoded hash) packet receipt from NODE node. If no
-pkt is specified, then acknowledge all packet in node’s
rx spool. If -all is specified, then do that for all
nodes.
That commands outputs list of created encrypted ACK packets
(NODE/PKT) to 4th file descriptor. That output can be
passed for example to nncp-rm to remove them after
transmission to not wait for acknowledgement and retransmission.
