Book Description
"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!

Book Description
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!

Book Description
You asked. He didn’t answer. The We Get Letters column of the FreeBSD Journal has been called “a tsunami of bile disguised as experience and erudition,” “a torment to the eye and a stain upon the soul,” and “the corroded battleship anchor that will drag an otherwise illustrious Journal to an ignominious demise.” If you ask people who aren’t the columnist, you’ll get a less luminous view. Perhaps even negative. We sincerely apologize. This collection of the first three years illustrates how rapidly Lucas abandoned any pretense of answering questions usefully—or, indeed, paying any attention whatsoever to his correspondents. It is unacceptable. What the editors conceived of as an innocent letters column quickly transcended bitterness to become elevated, even elegant enmity. Against everyone. Apologies are insufficient. In an attempt to keep these columns from teaching other articles bad habits, we have confined them in their own private volume. The publisher expects it to be presented as evidence at his inevitable competency hearings, as well as most of the civil suits. Next week’s suits, at least. "While we appreciate Mr Lucas' unique contributions to the Journal, we do feel his specific talents are not being fully utilized. Please buy his books, his hours, autographed photos, whatever so that he is otherwise engaged." – John Baldwin, FreeBSD Journal Editorial Board Chair
