tomo3D is a multi-platform voxel-based program for the viewing and manipulation of 3D tomographic reconstructions. It offers a refined toolset to identify blurred, hardly separable 3D objects. Its tools enable global image manipulation operations as well as local manual intervention.
trafcnt is an IP accounting scripts for a small LAN. It parses logs created by IPFM or any simillar source and calculates usage costs. It is possible to describe different schemes of operation for different users or groups. OpenBSD's pfctl is used for FW\NAT control, but trafcnt could be easily adapted to use almost anything. It produces clf- style logs.
tzls and tzx are commandline utilities for quickly unpacking or listing the contents of various types of common Unix archive files, which may be compressed in any of several ways. The supported compression types are bzip2, gzip, and compress. The supported archive types are tar, cpio, zip, rar, and arj. The tools are implemented as shell scripts, so no compilation is required.
The ucspi-tcp distribution contains tcpserver and tcpclient, which are easy-to-use command-line tools for building TCP client-server applications. tcpserver waits for incoming connections and, for each connection, runs a program of your choice. tcpclient makes a TCP connection and runs a program of your choice. This package includes several sample clients built on top of tcpclient: who@, date@, finger@, http@, tcpcat, and mconnect. tcpserver and tcpclient conform to UCSPI, the UNIX Client-Server Program Interface, using the TCP protocol. UCSPI tools are available for several different networks.
