The Mandos system allows computers to have encrypted root file systems and at the same time be capable of remote or unattended reboots. The computers run a small client program in the initial RAM disk environment which will communicate with a server over a network. All network communication is encrypted using TLS. The clients are identified by the server using an OpenPGP key that is unique to each client. The server sends the clients an encrypted password. The encrypted password is decrypted by the clients using the same OpenPGP key, and the password is then used to unlock the root file system.
/etc/net represents a new approach to Linux network configuration tasks. Inspired by the limitations of traditional network configuration subsystems, /etc/net provides built-in support for configuration profiles, interface name management, removable devices, full iproute2 command set, interface dependencies resolution, QoS, and firewall configuration frameworks. /etc/net provides support for the following interface types: ethernet, WiFi (WEP), IPv4/IPv6 tunnels, PSK IPSec tunnels, VLAN, PLIP, ethernet bonding and bridging, traffic equalizer, Pent@NET, Pent@VALUE, SkyStar-2, TUN/TAP, OpenVPN TUN/TAP, usbnet, and PPP. Due to its modular structure, support for new interface types can be added without overall design changes.
ramlog acts as a system daemon that maintains log files in memory instead of hard disk while the system is running. On startup, it creates a ramdisk, copies files from /var/log into the ramdisk, and mounts the ramdisk as /var/log. All logs after that will be updated on the ramdisk. When shutting down or restarting the service, it saves log files back to hard disk. This service drastically reduces the frequency of hard disk usage, which can be useful when the system runs on battery or uses flash memory instead of a hard disk.
Hotplug lets you plug in new devices and use them immediately. That means that users won't need to learn so much system administration, since the Linux system will at least partially autoconfigure itself. Initially, hotplug included support for USB and PCI (Cardbus) devices, and could automatically configure some common network interfaces. Updated versions include IEEE 1394 (Firewire/i.Link) support and can download firmware to USB devices that need it.
Instant Boot Server allows you to set up a Debian GNU/Linux chroot environment and install a TFTP boot server onto it. Three "boot methods" are provided, one for providing the clients with the Debian Installer, one for providing an NFS root, and one for testing/playing with custom-built kernels and initrd images. The boot server is started and stopped on demand. The main program (shell script) is extensible, and may be used to serve as a platform for adding other server types.
slakbootIBS (Slackware Interactive Boot Scripts) is an enhanced set of replacement boot scripts for the Slackware Linux distribution. It includes a set of control and dispatch tools for configuring and booting with colorized interactive scripts. The new boot process allows the operator to select or skip start-up components in realtime. It facilitates debugging of startup problems and allows operators to maintain a common baseline to support several local configurations or multiple servers with a single set of scripts.
