EndoShield is a fully configurable firewall that will run under a 2.2 or 2.4 Linux kernel (ipchains or iptables). It requires no knowledge of firewalls or how ipchains or iptables works. It is perfect for home users wanting to secure their systems, but can also be configured for internet connection gateways or server systems.
rs reads its input into an array of rows and columns, applies a specified transformation to the array, and writes it out with the specified number of rows and columns. It can be used to do column formatting and tidying of text, to transpose rows to columns and columns to rows (word-by-word, not character-by-character), and as a wrapper around line-oriented tools to let them handle multiline data. Rs is often distributed together with jot and lam, sometimes under the name bsd-utils.
Jsh is a Java shell or a Java launcher, a program with a prompt that allows you to type a sequence of commands. For example, you can use it to start a Java program simply by typing its main class. All applications you run in jsh are managed by the same JVM. Jsh also supports Java webstart (jnlp) applications.
