Conversion Tools: Networking
Tableutil
is a utility for converting, aggregating, and performing
operations (currently unions, differences, complements, and
intersections) on lists of IP addresses. Its primary use is to convert
files into a format pfctl(8) can read. It can read plain-text files with
ranges (12.12.12.12-23.23.23.23), CIDR-style networks (192.168.0.0/24),
single addresses (242.242.242.242), or host names (one.two.com). It can
also read p2b files, the preferred file-format of PeerGuardian.

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.

JH2N
(Java host to named conversion program) converts a hosts file
to a full BIND 8 or 9 configuration. JH2N was inspired by the h2n.pl
program included in the O'Reilly "DNS and BIND" book. Various options are
available to enhance its operation by incuding external files. Using the
simple host file syntax, very large and complex zones can be maintained.

cache2hints
is a simple utility to convert BIND cache dumps to hints
files usable by BIND. This allows BIND to recover a previous state, a
boon to dialup users and others who must restart BIND for some reason.
