ifdepd implements dependencies between network interfaces in a
reliable way. If any of the source interfaces fails, ifdepd sets all
destination interfaces to state down. If all source interfaces are active,
ifdepd sets all destination interfaces to state up.
For example, it can be used with carp(4) to provide failover functionality
on gateways/firewalls.
ifdepd is a simple replacement for ifstated and was written because of problems
with ifstated.

Iffinder is a tool for discover IP interfaces which belong to same
router.
KNC is Kerberised NetCat. It works in basically the same way as either netcat
or stunnel except that it is uses GSS-API to secure the communication. You can
use it to construct client/server applications while keeping the Kerberos
libraries out of your programs address space quickly and easily.
Bindings for GNU libgsasl.
Client library for the XMPP protocol.
This is a piece of software that lets you tunnel IPv4 data through a DNS
server. This can be usable in different situations where Internet access is
firewalled, but DNS queries are allowed.
The HTTP Time Protocol (HTP) is used to synchronize a computer's time
with web servers as reference time source. Htpdate will synchronize your
computer's time by extracting timestamps from HTTP headers found
in web servers responses. Htpdate can be used as a daemon, to keep your
computer synchronized.
Accuracy of htpdate is usually better than 0.5 seconds (even better with
multiple servers). Htpdate can also work through http proxy.
Convert valid IPv6 addresses to ip6.int PTR values. Convert valid
IPv4 addresses to in-addr.arpa PTR values. Anything not valid is
simply printed as is. Handles :: notation and embedded IPv4
addresses. If the address is followed by /n, the PTR is truncated
to n bits.
"httpry is a specialized packet sniffer designed for displaying and logging
HTTP traffic. It is not intended to perform analysis itself, but to capture,
parse, and log the traffic for later analysis. It can be run in real-time
displaying the traffic as it is parsed, or as a daemon process that logs to an
output file. It is written to be as lightweight and flexible as possible, so
that it can be easily adaptable to different applications."
