cfsm is a finite state machine compiler. It converts a high-level text description of a state machine into a C source and header file, and optionally a Graphviz dot graph. The generated code ensures that only explicitly permitted state transitions are possible, and supports optional precondition and transition callbacks.
flashboot for OpenBSD is a set of makefiles, scripts, and support tools to build an OpenBSD image suitable for booting from read-only media, such as flash memory. The default image (smaller than 5Mb) is an image for a firewall/router with support for IPsec, SSH, IPv4 and IPv6 packet filtering, DHCP (client and server), and PPPoE. This image may be further trimmed or extended by editing the packing list files included in the distribution.
flowd is a small, fast, secure, and featureful NetFlow collector. It supports NetFlow versions 1, 5, 7, and 9 over IPv4 and IPv6 transports, IPv6 flows (using NetFlow 9), filtering and tagging of received flows using a packet filter-like language, Perl and Python APIs, flexible storage (with run-time selection of which NetFlow fields are stored), reception of multicast flow datagrams, and privilege separation for security. The flowd distribution also includes a set of supplemental tools including analysis and SQL database support.
jBCrypt is a Java implementation of OpenBSD's Blowfish password hashing code, as described in "A Future-Adaptable Password Scheme" by Niels Provos and David Mazières. This system hashes passwords using a version of Bruce Schneier's Blowfish block cipher, with modifications designed to raise the cost of off-line password cracking and frustrate fast hardware implementation. The computation cost of the algorithm is parametised, so it can be increased as computers get faster. The intent is to make a compromise of a password database less likely to result in an attacker gaining knowledge of the plaintext passwords.
pfflowd is a small daemon which converts real-time state expiry messages from OpenBSD's PF packet filter into Cisco NetFlow datagrams. This allows very fine- grained traffic accounting in conjunction with NetFlow capable tools and places almost no incremental load on a PF firewall.
py-bcrypt is a Python wrapper of OpenBSD's Blowfish password hashing code, as described in "A Future-Adaptable Password Scheme" by Niels Provos and David Mazières. This system hashes passwords using a version of Bruce Schneier's Blowfish block cipher with modifications designed to raise the cost of off-line password cracking and frustrate fast hardware implementation. The computation cost of the algorithm depends on a parameter, so it can be increased as computers get faster.
py-radix is an implementation of a radix tree data structure for the storage and retrieval of IPv4 and IPv6 network prefixes. The radix tree is the data structure most commonly used for routing table lookups. It efficiently stores network prefixes of varying lengths and allows fast lookups of containing networks.
softflowd is a software flow-based network monitor. It tracks network traffic flows, reports aggregate statistics, and optionally exports Cisco Netflow compatible datagrams (to unicast hosts or multicast groups). It can listen on a promiscuous network interface or read store pcap capture files, and includes a sophisticated control interface.
traffic-vis is a suite of tools to help determine which hosts have been communicating on an IP network, with whom they have been communicating and the volume of communication taking place on a host by host basis. Reports can be generated in ASCII and/or HTML format. traffic-vis can also generate Postscript(tm) and GIF charts showing which hosts have communicated with each other.
