Open Watcom consists of the famous Watcom C++ and WATFOR compilers -- now open source. Open Watcom is mainly used for developing embedded, DOS, and ncurses software. Open Watcom includes the C/C++/Fortran IDE from Watcom for DOS and a full set of command-line tools for compilation, including the superb Watcom debugger. Open Watcom emits easy-to-understand errors and warnings when things go wrong. Open Watcom generates small statically linked binaries for Linux, Win32, Win16, OS/2, QNX, NetWare, and MS-DOS real and protected mode, among other targets. However, Open Watcom is still only beta-quality on Linux and BSD. The two most serious issues are imperfect C++ template support and an inability to dynamically link with shared libraries built by GCC. Also, Open Watcom is released under the Sybase Open Watcom Public License, which is considered non-free by most Debian Linux developers. NOTE: Open Watcom binaries for Linux are not available anywhere. You must build it yourself. 1.5 has known build issues on Linux; use version 1.4 or the current daily build instead.
librfid is a RFID protocol stack for RFID readers. It implements the reader side of ISO 14443 A and B, ISO 15693, Philips Mifare Ultralight, and Classic. It currently supprorts the Omnikey Cardman 5121 and OpenPCD RFID readers. Support for Philips Pegoda is currently under development. librfid uses libusb and should work on all operating systems that support libusb. Only Linux has been tested.
Webfwlog is a Web-based firewall log reporting and analysis tool. It allows users to design reports to use on logged firewall data in whatever configuration they desire. Included are sample reports as a starting point. Reports can be sorted with a single click, or "drilled-down" all the way to the packet level, and saved for later use. Supported log formats are netfilter, ipfilter, ipfw, ipchains, Cisco routers, Snort, and Windows XP. Netfilter support includes ulogd MySQL or PostgreSQL database logs using the iptables ULOG or NFLOG target.
Sshbak is very simple but powerful and secure remote backup utility. It performs a fast and comprehensible daily (usually) backup of multiple machines via remote SSH connections. The result is a simple set of tar+gzip files. It supports the backup of piped program output (allowing remote backup of mysqldump or pg_dumpall results), parallel backup of different machines, and more.
ngIRCd is a portable IRC daemon written from scratch. It is easy to configure, supports server links (even with original ircds) and runs on hosts with changing IP addresses (such as dial-in networks). Currently supported platforms are AIX, A/UX, Darwin/Mac OS X, FreeBSD, HP-UX, IRIX, Linux, NetBSD, SunOS/Solaris, and Windows with Cygwin.
OpenXPKI is a Web and CLI-based enterprise-grade PKI/trust center system (X509 public key infrastructure) complete with CA, Web interfaces, offline support, and support for well established infrastructure components like RDBMS and Hardware Security Modules. Flexibility and modularity are the project's key design objectives. Unlike many other PKI solutions, it offers powerful features necessary for professional environments. However, small scale installations are also targeted by providing quick-start configuration examples that allow you to get a usable PKI running quickly.
The dkLab Apache is a patched Apache distribution for those who plan to use the Apache Web server to serve multiple separate sites working under different, fully separated, and independent Unix users. It does not require you to install any OS kernel modules or disable setuid, and works correctly and intelligently with KeepAlive turned on and MaxRequestsPerChild greater than 1.
romfser is userland program for listing, extracting, and partially mangling romfs images. You can provide it with an offset in an image where the file system starts. The mangling ability is expressed in file substitution, where the new file has to be equal or smaller in size compared to the file being replaced. It can extract single files into the current directory or extract the whole filesystem while preserving the directory structure.
