Uplog is an UDP-based ping program that gives an ASCII graphical log of packet loss. Once per second, it sends a UDP packet to the echo port of the target host and waits for a reply. If it gets a reply an X is written, otherwise a dot is written to the log file. If a packet with an incorrect sequence number arrives, a colon is written to the log file. By examining the log file, one can easily see when and how the packet losses occur.

Libkvkontakte is a KDE C++ interface for VK (http://vk.com).

SMCRoute is a command line tool to manipulate the multicast routes of a UNIX kernel. It supports both IPv4 and IPv6 multicast routing. SMCRoute can be used as an alternative to dynamic multicast routers like mrouted or pimd in setups where static multicast routes should be maintained and/or no proper IGMP or MLD signaling exists.

A tool to quickly ping N number of hosts to determine their reachability without flooding the network. fping is different from ping in that you can specify any number of hosts on the command line, or specify a file containing the lists of hosts to ping. Instead of trying one host until it timeouts or replies, fping will send out a ping packet and move on to the next host in a round-robin fashion. If a host replies, it is noted and removed from the list of hosts to check. If a host does not respond within a certain time limit and/or retry limit it will be considered unreachable. Unlike ping, fping is meant to be used in scripts and its output is easy to parse.

Sniffit is a network sniffer for TCP/UDP/ICMP packets. Sniffit produces very detailed technical details about the packets flowing through your network (SEQ, ACK, TTL, Window, ...) and also packet contents in different formats (hex or plain text, ...)

Sobby is a stand-alone server for the collaborative editor gobby and other obby users.

sngrep - SIP Messages flow viewer sngrep is a terminal tool that groups SIP (Session Initiation Protocol) Messages by Call-Id, and displays them in arrow flows similar to the used in SIP RFCs. The aim of this tool is to make easier the process of learnig or debugging SIP. It recognizes UDP, TCP and partially TLS SIP packets and understands bpf filter logic in the same way ngrep and tcpdump does.

This is a standalone version of W. Richard Stevens' "sock" program, based on the code available for the UNIX Network Programming book. Adapted and reworked code for W. Richard Stevens' "sock" utility by Christian Kreibich. From the author: In TCP/IP Illustrated Vol. 1, Richard Stevens used a program called "sock" to demonstrate the many properties of TCP/IP. Unfortunately, the book only speaks about how to use the program but does not point to a site for downloading its sources. While sock is contained in the code package accompanying UNIX Network Programming, this code is also getting dated. The program can be used to generate TCP or UDP packets for testing various network features. It runs as either client or server.

socat is a relay for bidirectional data transfer between two independent data channels. Each of these data channels may be a file, pipe, device (terminal or modem etc.), socket (UNIX, IP4, IP6 - raw, UDP, TCP), a file descriptor (stdin etc.), a program, or an arbitrary combination of two of these. socat can be used, e.g., as TCP relay (one-shot or daemon), as an external socksifier, for attacking weak firewalls, as a shell interface to UNIX sockets, IP6 relay, for redirecting TCP oriented programs like brutus to a serial line, or to establish a relatively secure environment (su and chroot) for running client or server shell scripts with network connections.
