Last anecdotal point, it was Bruce who was responsible for inspiring the different“codenames” for Debian versions (1.1 — Rex, 1.2 — Buzz, 1.3 — Bo, 2.0 — Hamm, 2.1 — Slink, 2.2 — Potato, 3.0 — Woody, 3.1 — Sarge, 4.0 — Etch, 5.0 — Lenny, 6.0 — Squeeze, Testing — Wheezy, Unstable — Sid). They are taken from the names of characters in the Toy Story movie. This animated film entirely composed of computer graphics was produced by Pixar Studios, with whom Bruce was employed at the time that he lead the Debian project. The name “Sid” holds particular status, since it will eternally be associated with the Unstable branch. In the film, this character was the neighbor child, who was always breaking toys — so beware of getting too close to Unstable. Otherwise, Sid is also an acronym for “Still In Development”.. If the server is a Unix machine offering shell accounts to users, it is interesting to determine if processes are executed in the background in the absence of their owner. The commandps auxw displays a list of all processes with their user identity. By checking this information against the output of thewho command, which gives a list of logged in users, it is possible to identify wild servers or programs running in the background. Looking at crontabs (tables listing automatic actions scheduled by users) will often provide interesting information on functions fulfilled by the server (a complete explanation ofcron is available in Section 9.7, “Scheduling Tasks withcron andatd”).. Architecture(s). The main configuration is in the /etc/dirvish/master.conf file. It defines the location of the backup storage space, the list of“vaults” to manage, and default values for expiration of the backups. The rest of the configuration is located in thebank/vault/dirvish/default.conf files and contains the specific configuration for the corresponding set of files..         reject_unauth_destination,. http://localhost:631/admin.. RAID-1. Let us now follow, step by step, the process of setting up LVM for a typical use case: we want to simplify a complex storage situation. Such a situation usually happens after some long and convoluted history of accumulated temporary measures. For the purposes of illustration,

we’ll consider a server where the storage needs have changed over time, ending up in a maze of available partitions split over several partially used disks. In more concrete terms, the following partitions are available:.   Physical volume “/dev/sdb2” successfully created. QEMU is a software emulator for a full computer; performances are far from the speed one could achieve running natively, but this allows running unmodified or experimental operating systems on the emulated hardware. It also allows emulating a different hardware architecture: for instance, ani386 system can emulate anarm computer. QEMU is free software.. PERSPECTIVE X11, XFree86 and 13.5. Emulating Windows: Wine. Managing SELinux Modules. A more advanced attacker will go beyond that. A disaster scenario could go on in the following fashion: the attacker gains the ability to execute commands as the www-data user, but executing a command requires many manipulations. To make their life easier, they install other web applications specially designed to remotely execute many kinds of commands, such as browsing the filesystem, examining permissions, uploading or downloading files, executing commands, and even provide a network shell. Often, the vulnerability will allow running awget command that will download some malware into /tmp/, then executing it. The malware is often downloaded from a foreign website that was previously compromised, in order to cover tracks and make it harder to follow the scent to the actual origin of the attack.. The starting point of this hierarchical tree is called the root, /. This directory can contain named subdirectories. For instance, the home subdirectory of / is called /home/. This subdirectory can, in turn, contain other subdirectories, and so on. Each directory can also contain files, where the actual data will be stored. Thus, the /home/rmas/Desktop/hello.txt name refers to a file named hello.txt stored in the Desktop subdirectory of the rmas subdirectory of the home directory present in the root. The kernel translates between this naming system and the actual, physical storage on a disk..
