wshare is a simple solution to share an existing network connection from the commandline. There are two modes, master and client. The master shares an existing network connection (probably to the Internet) via an unused wireless device. The client can connect either through the operating system provided facilities or with this script in client mode.
grindr is a set of various utilities to enhance Web productivity. It provides tools to interact with Web sites, RSS feeds, and instant messaging. Munchr is a simple RSS parser which can collect data from restricted Web sites, and this data is routed to nbox. nbox is a small GUI display for all collected information. Posting information is done by feedr, which takes a set of parameters and values and submits it to the appropriate Web service. gaskr provides a GUI to prepare data for feedr. Initial configuration for gaskr is prepared by bildr, which can log onto sites and scrape all form data from HTML content.
The KornShell language is an interactive command language that provides access to the Unix system and to many other systems, on the many different computer systems on which it is implemented. The KornShell language is also a complete, powerful, high-level programming language for writing applications, often more easily and quickly than with other high-level languages. This makes it especially suitable for prototyping. There are two other widely used shells, the Bourne shell developed by Steven Bourne at AT&T Bell Laboratories, and the C shell developed by Bill Joy at the University of California. ksh has the best features of both, plus many new features of its own. Thus ksh can do much to enhance your productivity and the quality of your work, both in interacting with the system, and in programming. ksh programs are easier to write, and are more concise and readable than programs written in a lower level language such as C.
Even for beginners it is definitly worth trying.
some things are missing though, MARKs for QoS, and ULOG support is only available via iptables commands. that needs some work. otherwise a really great approach to iptable configs!
