IsinGlass is a firewall setup script designed to protect dial-up users (but also useful for others). It protects your system against security holes in programs the user may not even know they're running. Most users can run it "out of the box" without any configuration required. It will automatically detects network interfaces and IP addresses. Now works with ipchains.
The Internet Software Consortium DHCP distribution includes a DHCP client, a DHCP server, and a DHCP relay agent. DHCP is a protocol for automatically configuring nodes on an IP network. The ISC DHCP server and client are well known for being extremely configurable, reasonably easy to use, and quite efficient.
The netpipes package makes TCP/IP streams usable in shell scripts. It can also simplify client/server code by allowing the programmer to skip all the tedious programming bits related to sockets and concentrate on writing a filter/service. <P>Applications of these utilities can include file transfer, network backups, HTTP queries, remote procedure calls, and TCP daemon testing. <P>The SSL encryption filter available in the US/Canada version can be applied by shell scripts communicating with secure HTTPDs and can be used to make an SSL IMAPD out of a non-SSL one. (requires the SSLeay library).
Tinyproxy is a light-weight HTTP/HTTPS proxy daemon for POSIX operating systems. Designed from the ground up to be fast and yet small, it is an ideal solution for use cases such as embedded deployments where a full featured HTTP proxy is required, but the system resources for a larger proxy are unavailable.
tircproxy is a full featured IRC proxy. It can proxy DCC CHAT, DCC SEND and other DCC requests transparently to the user, block common trojans (such as script.ini), hide the user's identity and more. It can be used with the Linux kernel or IPF transparent proxy features to transparently proxy IRC sessions.
The Linux joystick driver provides support for joysticks under Linux. The 1.2.14 version supports classic analog PC joysticks, ThrustMaster FCS, CH Flightstick Pro and 6/8- button gamepad compatible extensions, digitally communicating joysticks from Creative, FPGaming, Genius, Gravis, Logitech, MadCatz, Microsoft, SpaceTec, ThrustMaster, PDPI L4 gamecard, as well as various (NES, SNES, Sega, PSX, Atari, Amiga, Commodore, Amstrad) gamepads and joysticks connected to the PC's parallel port.
gpppkill is a program for Linux that ends a ppp connection if it doesn't receive a minimal amount of bytes during certain time. It shows a bar plot according to the amount of bytes received per second. All resident ppp daemons are recognized and gpppkill lets you choose which one to kill. It is written in C++ using the GTK+ toolkit.
The Advanced Linux Sound Architecture is composed of several parts. The first is a fully modularized sound driver which supports module autoloading, devfs, isapnp autoconfiguration, and gives complete access to analog audio, digital audio, control, mixer, synthesizer, DSP, MIDI, and timer components of audio hardware. It also includes a fully-featured kernel-level sequencer, a full compatibility layer for OSS/Free applications, an object-oriented C library which covers and enhances the ALSA kernel driver functionality for applications (client/server, plugins, PCM sharing/multiplexing, PCM metering, etc.), an interactive configuration program for the driver, and some simple utilities for basic management.
