Sudo Mastery by Michael W Lucas Pdf

Sudo: You’re Doing It Wrong Unix-like operating systems use a rudimentary access control system: the root account can do anything, while other users are peasants with only minimal access. This worked fine in UNIX’s youth, but now that sysadmin responsibilities are spread among many people and applications, many people need a tiny slice of root’s power. Sudo lets you divide root’s monolithic power between the people who need it with accountability and auditability. Sudo Mastery will teach you to: · design a secure sudo policy · simplify policies with lists and aliases · manage shell environments · verify system integrity via intrusion detection · deploy a single sudo policy across your enterprise · manage sudo policies via LDAP · log and debug sudo · record and replay full sudo sessions · use authentication systems other than passwords Master sudo with Sudo Mastery!

OpenBSD Mastery: Filesystems by Michael W. Lucas Pdf

"Many users assume that their advanced filesystem is better than UFS because they have so many features—snapshots, checksums, compression, sophisticated caching algorithms, and so on—while all UFS has ever done is muck about putting data on disk. But, conversely, UFS users believe their filesystem is better for exactly the same reasons." —Hitchhikers Guide to OpenBSD Disk management is the core of system administration. Nobody can tell you how large that database is going to grow or how many files that archive must eventually support, but for everything else there’s OpenBSD Mastery: Filesystems. This guide takes you through the latest in OpenBSD storage management, including: · OpenBSD’s cross-platform storage stack · MBR, GPT, and disklabel partitions · The Unix File System · Growing, removing, and repairing filesystems · Memory file systems · The Buffer Cache · Why you need swap, and how to live with it · Coping with FAT, NTFS, EXT, and more · The Network File System · iSCSI · Software RAID · Encrypted filesystems · Encrypted installs And more!
