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."

ipsvd is a set of internet protocol service daemons. It currently includes a TCP/IP service daemon, and a UDP/IP service daemon. An internet protocol service (ipsv) daemon waits for incoming connections on a local socket. On incoming connections, the ipsv daemon conditionally runs an arbitrary program with standard input reading from the socket, and standard output writing to the socket, that handles the connection. Standard error is used for logging. ipsv daemons can be told to read and follow pre-defined instructions on how to handle incoming connections. It's possible to run different programs, or to set a different environment, or to deny a connection, or to set a per host concurrency limit, depending on the client's address or hostname. Normally the ipsv daemons are run by a supervisor process, such as runsv from the runit package, or supervise from the daemontools package. ipsvd can be used to run services normally run by inetd, xinetd, or tcpserver.

Herqq UPnP (HUPnP) is a software library for building UPnP devices and control points conforming to the UPnP Device Architecture version 1.1.

ICPLD (Internet Connection Performance Logging Daemon) is a daemon which, by sending ICMP requests to an IP address of your choice, monitors whether your machine has a working network connection. It will log any failed attempts, and will stamp a log as soon as a reply is received. It keeps track of when the connection was unavailable, as well as for how long. It records both total down time and each occasion of interrupted connection. The log can also be duplicated in HTML format to put online.

ifstat is a tool to report network interfaces bandwith just like vmstat/iostat do for other system counters.
