ULTRIX Reference Pages Section 8: Maintenance

This document is "ULTRIX Reference Pages Section 8: Maintenance," published in June 1990 for ULTRIX Version 4.0 or higher.

It serves as a comprehensive reference guide for system administrators, detailing a wide array of commands essential for system operation and maintenance on both RISC and VAX platforms. Each command's reference page typically includes its name, syntax, a detailed description, available options, operational restrictions, practical examples, relevant files, and cross-references to related documentation.

Key areas covered by the commands in this Maintenance section include:

• System and File System Management: Commands for creating, checking, and repairing file systems (newfs, mkfs, fsck, dcheck, icheck), managing disk partitions (chpt, bad144, badsect, radisk, rzdisk), performing system dumps and restores (dump, restore, rdump, rrestore), and handling disk quotas (quot, quotacheck, edquota, repquota, quotaon).
• Network Services: Utilities for configuring and managing network interfaces (ifconfig), routing (route, routed), network time synchronization (ntpd, timed), domain name services (BIND/Hesiod via named, bindsetup), remote execution and login (rexecd, rlogind), file transfer protocols (ftpd, tftpd), and various network daemons (portmap, snmpd, statd, rwalld, rwhod). It also covers Kerberos security management (kdb_init, kinit, kstash, kprop, etc.).
• User and Account Management: Tools for adding and removing user accounts and groups (adduser, removeuser, addgroup), managing authentication databases (getauth, setauth, edauth), and password file maintenance (mkpasswd, vipw).
• System Monitoring and Diagnostics: Commands for error logging (elcsd, eli, uerf), analyzing system crashes (crash, savecore), gathering system statistics (pstat, nfsstat, pac, syslog), and running various system exercisers for hardware components like disk, tape, memory, and network (dskx, mtx, memx, netx, lpx, cmx, syscript).
• System Control and Configuration: Commands for system startup and shutdown procedures (init, rc, reboot, halt, shutdown), configuring the kernel (config, doconfig), managing diskless client environments (dms), installing and managing software subsets (setld, fitset), and adjusting process priorities (renice).
• Printer Management: Tools for setting up and controlling printers (lprsetup, lpc, lpd) and various printer filters (ansi_ps, regis_ps, tek_ps, la750f, lcg01of, ln01of, ln01pp, ln03of, ln03rof, lpf, xf, xlator_call).
• UUCP Utilities: Commands for managing UUCP spool directories (uucompact, uuclean, uurespool, uupoll), file transfers (uucico), and setup (uucpsetup, uumonitor).

The document also explains general documentation conventions, including how platform-specific information (RISC, VAX) is indicated.
