libcsdbg is a C++ exception stack tracer. When an exception is thrown, caught, and handled, libcsdbg offers the tools to create and process the exception stack trace, the path the exception has propagated up the call stack, unwinding it up to the section were it was handled. The traces are detailed with demangled function signatures and additional addr2line information (the source code file and line from which each function was called). libcsdbg can use all the well-known objective code file formats (a.out, elf, coff, ecoff, etc.) and can easily be used as the base for your own instrumentation code. libcsdbg transparently loads the symbol tables of the chosen dynamic libraries and of the executable, demangles function symbols to complete signatures, and binds function names to runtime addresses (even for the DSO symbols).
fio is an I/O tool meant to be used both for benchmark and stress/hardware verification. It has support for 19 different types of I/O engines (sync, mmap, libaio, posixaio, SG v3, splice, null, network, syslet, guasi, solarisaio, and more), I/O priorities (for newer Linux kernels), rate I/O, forked or threaded jobs, and much more. It can work on block devices as well as files. fio accepts job descriptions in a simple-to-understand text format. Several example job files are included. fio displays all sorts of I/O performance information, including complete IO latencies and percentiles. Fio is in wide use in many places, for both benchmarking, QA, and verification purposes. It supports Linux, FreeBSD, NetBSD, OpenBSD, OS X, OpenSolaris, AIX, HP-UX, Android, and Windows.
LinOTP is a solution for strong two-factor authentication with one time passwords. It features a modular architecture into which UserIdResolver, authentication, and OTP calculation modules can be plugged. It includes UserIdResolver modules for LDAP/AD, SQL, and flat file user databases, and authentication modules for PAM and RADIUS. New modules can be developed easily. Supported tokens are HMAC-OTP/HOTP (RFC 4226/ OATH compliant), Aladdin eToken PASS, eToken NG-OTP, Safeword Alpine, Yubikey, Google Authenticator, motp, SMS OTP/Mobile TAN, email token, and a Simple Pass token for users without token hardware. TOTP is supported, along with a new algorithm for daily passwords for applications not supporting RADIUS. OCRA tokens are supported to allow transaction signing in banking environments. CLI, Web, and GTK+ GUI clients are available for management. LinOTP features multi-client capability, redundancy, and a self-service portal. It has been used with PAM for local and SSH logins, Apache, VPN, and Windows Terminal Server, and is OATH certified.
SaluSafe is an encrypted email, chat, and file storage and sharing system. Your email and files are highly encrypted end-to-end, and cannot be intercepted by any third party. It was built from the ground up for security via strong cryptography, and is not just another security wrapper on top of an existing email solution.
