lxt (linuXtree) is a file manager program that was inspired by the popular DOS program XTreeGold. Most of the keyboard shortcuts are the same and the interface is similar, but it has been modified a bit to better suit the features of Unix such as long file names and file permissions.
NOC Project is an Operation Support System (OSS) for telecom companies, service providers, and enterprise Network Operation Centers (NOC). Areas covered by NOC include fault management, performance management, service activation/provisioning, knowledge base, multi-VRF address space management (IPAM), multi-vendor configuration management, DNS provisioning, peering management, RPSL and BGP filter generation, and reporting.
passwdqc is a password/passphrase strength checking and policy enforcement tool set, including an optional PAM module (pam_passwdqc), command-line programs (pwqcheck and pwqgen), and a library (libpasswdqc). On systems with PAM, pam_passwdqc is normally invoked on password changes by programs such as passwd(1). It is capable of checking password or passphrase strength, enforcing a policy, and offering randomly-generated passphrases, with all of these features being optional and easily (re-)configurable. pwqcheck and pwqgen are standalone password/passphrase strength checking and random passphrase generator programs, respectively, and are usable from scripts. libpasswdqc is the underlying library, which may also be used from third-party programs.
MacPorts makes the world of open source software available to your Mac. There are over 5600 software titles ("ports"), each one installable with a single command. This is probably the biggest, most up to date open source software collection for Mac OS X. MacPorts works much like the ports collections of the major BSD operating systems.
The Logfile Navigator, lnav for short, is a curses-based tool for viewing and analyzing log files. The value added by lnav over text viewers or editors is that it takes advantage of any semantic information that can be gleaned from the log file, such as timestamps and log levels. Using this extra semantic information, lnav can do things like interleaving messages from different files, generate histograms of messages over time, and provide hotkeys for navigating through the file. These features are meant to allow the user to quickly and efficiently focus on problems.
sdparm has a command line interface for getting and setting SCSI mode page fields. Fields can be referred to by an acronym or a numerical address. It has support for various SCSI transport and vendor-specific mode pages. It also decodes Vital Product Data (VPD) pages and can send some simple SCSI commands. sdparm was originally written for Linux with ports to FreeBSD, Solaris, Tru64, and Windows.
msulogin is the single-user mode login program used to force the console user to login under a root account before a shell is started. Unlike other implementations of sulogin, this one supports having multiple root accounts on a system. msulogin has been developed as a part of Openwall GNU/*/Linux and is being made available separately primarily for use by other distributions. Currently, msulogin supports only systems with getspnam(3).
