OpenSMTPD is an RFC compliant, secure, and simple SMTP server ported from OpenBSD to Linux. It supports the SMTP protocol, including SSL versions for added security, virtual domains, forward files, and external delivery agents like procmail, and can do most of the basic things that other MTA implementations do.
cproto generates function prototypes for functions defined in the specified C source files to the standard output. The function definitions may be in K&R or ANSI C style, or in the lint library form. cproto can also convert function definitions in the specified files from the K&R style to the ANSI C style.
The GUIShell project is a collection of utilities facilitating the use of the GTK+ toolkit in shell scripts through the gtkshell utility. The ACE configuration environment provides sample scripts utilizing gtkshell for desktop utilities. rootcat provides the ability to display messages to the root window using Xft, allowing one to write status display scripts.
dwarf-ng is a small and powerful object file manipulator. With dwarf-ng, you can read, edit, and manipulate section headers, inject code or data, and create new section headers of object files. Currently, it handles object files in the PE, Mach-O, and ELF formats. For the moment, dwarf-ng only has a command-line interface. dwarf-ng is fully scriptable (as it has a scripting language), and is flexibly configurable.
Nonpareil is a microcode-level simulator for HP calculators introduced between 1972 and 1982, including the HP-35, HP-45, HP-55, HP-25, HP-34C, HP-38C, HP-41CV, HP-11C, HP-12C, HP-15C, HP-16C, and other models. The necessary microcode is included, as is a microcode assembler. The GTK+ toolkit is used for the user interface.
fsc2 is a program for controlling spectrometers. Experiments are done by interpretation of scripts written in a simple language, EDL. Devices are handled via modules in order to allow easy integration of new devices. More than 50 devices are supported, connected via serial port, GPIB, LAN, or USB as well as data acquisition cards, etc. The state of an experiment can be remotely monitored via a built-in Web server.
nefu (network fidelity utility) is a Unix daemon that monitors services over the network. It uses a "no false alarms" fault verification algorithm, and understands network dependancies. Natively-monitored protocols include ICMP echo (ping), SSH, IPP, DNS, HTTP, POP, NTP, IMAP, SMTP, and LDAP, as well as having facilities to execute external programs. Status pages are available via finger or the Web.
