Review week eighth lab assignment

Review week eight lab assignment Red Hat Package Manager (rpm) is a package management system. - Software package file format - Free software tool which installs, updates, uninstalls, verifies and queries other software packages in this format. rpm was originally targeted for the Linux distributions; the file format RPM is the baseline package format of the Linux Standard Base.

Review week eight lab assignment File format is a particular way to encode information for storage in a computer file. Disk drives or computer storage can on be in bits. Computer must convert information to 0s and 1s and vice-versa. Different kinds of formats for different kinds of information. JPEG format – designed to store static photographic images. GIF format – designed to store still images and simple animation. QuickTime format – designed as a container for many different types of multimedia.

Review week eighth lab assignment Package Advantages: - Used in a uniform way for the user to install programs - Uninstalling programs is simple - Non-interactive installation makes it easy to automate - Original source archive (e.g..tar.gz,.tar.bz2) - Packages can be cryptographically verified with GPG and MD5.

Week nine expected outcomes Upon successful completion of this module, the student will be able to: Analyze processes of startup and shutdown. Apply startup scripts and controls to tune system. Describe basic "autonomous" processes in UNIX.

Next Lab Assignment “Initializing” or “booting” the machine steps 1.CPU is pre-set to RESET mode 2.CPU pre-programmed to seek 0xfffffff0 address location 3.BIOS eventually reads MBR 4.First part of MBR contains the boot partition table and executable code 5.Second part of the MBR is used to locate the boot loader. It resides on the “active” partition known as the Boot Sector. 6.Device drivers are loaded (initrd img) 7.Kernel is invoked 8.Kernel performs the following tasks Memory size determination Hardware configuration Kernel data structure initialization Mount root partition Hand crafted init process

Next Lab Assignment Linux system run level modes 0 - Halt system 1 – Single user 2 – Multi-user mode 3 – Full multi-user 4 – unused 5 – X Reboot Shutdown command shutdown Review the Startup/Shutdown lab assignment

Next Lab Assignment /etc/fstab file descriptive information Read only file Each file system is described on a separate line. Fields are separated by tabs. Order of records in the fstab is important because of fsck, mount, and unmount are sequentially iterate through the fstab

Next Lab Assignment /etc/fstab file field descriptions First field - block special devices or remote filesystem to be mounted. Second field – mount point for the filesystem Third field – type of filesystem. Fourth field – mount options associated with the filesystem Fifth field – used by the dump command to determine which filesystems need to be dumped. Sixth field – determine order in which the filesystem is checks are done at boot time.

Next Lab Assignment Unix/Linux Commands who –r df df –I sar mv rm rmdir history tail mkdir

Break-out problems What functionality does the getty perform? Define the kernel responsive and autonomous functions? What functionality does the /etc/fstab file provide? What is the functionality of the /etc/inittab? Commands ls -li who -r kill kill –l fork-and-exec $$ $! telinit sleep

Upcoming deadlines Installation Exercise, 8-1 is due 6/29/08 Startup/Shutdown, 10-1 is due 7/6/08 Account/LDAP Script, 11-1 is due 7/13/08 Process Exercise, 11-2 is due 7/13/08 Demonstrate the newuid and process.sh functionality.
