The NET-SNMP (formerly UCD-SNMP) package contains various tools relating to the Simple Network Management Protocol including an extensible agent, an SNMP library, tools to request or set information from SNMP agents, tools to generate and handle SNMP traps, a version of the unix 'netstat' command using SNMP and a Tk/perl mib browser. It was originally based on the Carnegie Mellon University SNMP implementation (version 188.8.131.52), but has been greatly enhanced, ported and fixed and barely resembles the original package anymore.
LILO is a Boot loader for Linux/x86 and other PC operating systems. It is responsible for loading your Linux kernel from either a floppy or a hard drive and passing control to it. It is capable of booting beyond cylinder 1024 of a hard disk if the BIOS supports EDD packet call extensions to the int 0x13 interface. LILO can also be used to boot many other operating systems, including DOS, Windows (all versions), OS/2, and the BSD variants. The LILO distribution includes full source, documentation and support files.
Tcl provides a portable scripting environment for Unix, Windows, and Macintosh that supports string processing and pattern matching, native file system access, shell-like control over other programs, TCP/IP networking, timers, and event-driven I/O. Tcl has traditional programming constructs like variables, loops, procedures, namespaces, error handling, script packages, and dynamic loading of DLLs. Tk provides portable GUIs on UNIX, Windows, and Macintosh. A powerful widget set and the concise scripting interface to Tk make it a breeze to develop sophisticated user interfaces.
Usermin is a Web interface that can be used by any user on a UNIX system to easily perform tasks like reading mail, setting up SSH, or configuring mail forwarding. It can be thought of as a simplified version of Webmin designed for use by normal users rather than system administrators.
ArgoUML is a pure Java open source UML CASE tool that provides cognitive support for object-oriented design. ArgoUML provides some of the same editing and code generation features of a commercial CASE tool, but it focuses on features that enhance usability and support the cognitive needs of designers. Uses XML file formats: XMI and PGML.
