steven	5f10c27b0f	add knock sequence timeout ... This provides another layer of additional protection against sweep attacks by ensuring the correct sequence be entered rapidly, within 3 seconds by default. It also prevents a client from sitting stuck forever part way through an old knock sequence.	2024-04-14 18:14:24 -06:00
steven	2efe3344b4	knock frames should not contain any data, only headers	2024-04-13 21:50:20 -06:00
steven	0ad3e2b0d4	enter eBPF, libpcap and CGO = bloat	2024-04-13 21:22:22 -06:00
steven	ead7578544	change pcap snaplen to 126 bytes ... We really only care getting as far as the UDP header and can discard the rest. This should reduce load, and perhaps enable full pcap with ports on the BPF filter UDP header = 8 bytes IPv4 max size = 60 bytes IPv6 fixed size = 40 bytes Ethernet header size = 18 bytes	2024-04-11 15:21:48 -06:00
steven	291cbaabd4	BREAKING: changes to CLI interface, moved to cobra CLI ... To better support configuration and user friendliness, migrated to cobra based CLI. The source tree structure has also changed to single go module, the server has been renamed hypd and client has been named hyp. The original structure came into being organically, but now that the vision is more complete it's best to make these adjustments now.	2024-04-10 21:42:38 -06:00
