The satpass script provides satellite visibility predictions, given the position of the observer and the NORAD element sets for the desired satellites. It can acquire the NORAD element sets directly from any site supported by Astro::SpaceTrack. It can acquire the observer's latitude and longitude from http://geocoder.us/, look up star positions in the SIMBAD catalog, and more.
ssh-forcecommand is a script to safely execute remote commands via ssh. It is especially aimed at automated remote commands (in which ssh keys are not secured via password), where a compromise of the remote system could also compromise the local system. To prevent this, ssh-forcecommand can be invoked through the ssh configuration, which will limit the remote system so that it can only execute a set of statically defined commands. This way, compromising the local system is made much more difficult.
Tivima (Tiny Virtual Manager) is a simple Web administration tool for managing virtual machine hosts running KVM. It is not meant to manage large cloud farms or huge datacenters with thousands of servers, but is for small to mid-range organizations that wish to manage their libvirt/KVM hosts centrally from a Web browser. Tivima aims to be distribution independent.
ABC Path Generator is a program and a Perl library that generates layouts of ABC Path based on the input of a random number generator. Giving different seeds to the generator will yield different layouts. ABC Path is a puzzle game in which one should position the letters from "A" to "Y" in a 5*5 grid based on clues. It is featured on brainbashers.com. ABC Path Generator makes use of depth-first-search to find usable final paths, and then assigns the clues for it, also using DFS.
lpkfuse is a FUSE filesystem that lets you place all the SSH public keys of your users into LDAP. Without this tool, you would have to patch your SSH server (for example using openssh-lpk) to support this. But with lpkfuse, you just need to amend AuthorizedKeysFile in your sshd_config file. Other benefits include LDAP resilence and caching/local-fallback in case no LDAP servers are accessible.
