History of UNIX and distributed computing

Solaris operating environment: SunOS, OpenWindows, DeskSet and CDE

UNIX operating system design: hardware core, kernel, shell, application.

Roles of servers and clients

Host configuration: standalone and diskless clients

Software terminology

Users: superuser (root) and user

System Access: user account and password, special systems accounts

Logging in!

UNIX file systems – file tree, file-based operating system

Commands (case sensitive): pwd, cd, ls, more, grep, mv, cp, ln, rm, rmdir mkdir, touch, and cat

Graphics Interface (File manager)

Text Editors: vi, and window-based text editor

Using vi

Use various commands

Use vi to create and edit a file

System boot and shutdown procedures

System run-levels

Boot sequence

Change run-levels: shutdown, halt, init, reboot, stop-A commands

Managing user accounts

admintool: an overview

Commands (group add, groupmod, groupdel; useradd, usermod, userdel, and passwd)

home directory, default shells and initialization files for users and superusers

Managing System Security

Owner, group, and permissions

chown and chgrp commands

Setting permission using symbolic names

Using Octal numbers

Setting the default file mode (umask)

Set UID and GID

Tracking security using aset

Reboot, power-off systems

Create user accounts using both admintool and commands

Set and change permissions of files and directories

Solaris Device Names

Device terminology

eeprom device mappings (electronically erasable programmable read only memory)

(printenv, setenv commands)

OpenBoot Monitor physical Names: name@address:arguments

Logical device names (alphabet Soup Device Names)

Displaying system configurations: prtconf, sysdef

Reconfiguring device information (boot –r)

Adding a SCSI disk

Using the format utility

Viewing the VTOC (volume table of contents) with the prtvtoc utility

Types of file systems (ufs, hsfs, pcfs, nfs, tmpfs, cachefs, lofs, procfs, and swapfs)

Creating new file system (newfs /dev/rdsk/c#t#d#s#)

Identifying file systems mounted (df, mount, /etc/mnttab)

Mounting file systems (mount –o option, option, … disk_device mount_point

Starting and stopping volume manager: /etc/inet.d/volmgt start or /etc/inet.d/volmgt stop

Use device management commands: prtconf, sysdef, boot –r, prtvtoc, newfs, df, mount, volmgt start or stop

Software concepts: groups (configurations: core, end user, developer, and entire), clusters (OpenWindows Version 3), and packages (SUNWman)

Software maintainance Utilities: pkginfo, pkgadd, pkgrm, pkgchk

Graphic interface tools: admintool

Add a JetDirect package using "pkgadd –d /cdrom/hp_jetadmin/unix solaris.pkg"

Use admintool

Serial devices

Service Access Facility (SAF)

Service Access Controller: SAC

Port monitors: TTY port monitor (ttymon) and Network listen monitor (listen)

Setting up terminals, and moderms using admintool.

Printing

printing terminology: printing daemon—lpsched, print client and print server. spool directory, output filters (ascii to ps)

Printer setup: setup a local printer, and setup a remoter printer.

Access control: lpadmin –p basement –u deny:john

Starting and stopping the printing service: lpshut and /usr/lib/lp/lpsched, to check use lpstat –r.

Configuring and using HP JetDirect for network printing

Use sacadm, pmadm, and ttyadm

Install local and remote printers using admintoolModule 7: System Backups

Why backup?

What files need backups?

Types of backups

Backup commands: /usr/lib/fs/ufs/ufsdump, ufsrestore, tar, cpio, and dd

Automatic backup using scripts and crontab.

Basic shell features

Environment and local variables

Setting variables from .login

Using metacharacters, redirection characters, and quotation marks in scripts

Statements: which statement, loop control statements (for, while,); conditional statements (if conditional and case conditional)

Change environmental variables

Use metacharacters

Write simple scripts to automate backup

TCP/IP protocol suite

Network address and host address

Name services: /etc files, DNS and NIS+ -- an introduction

Netmasks, subnets, and routers

Local configuration files: /etc/hosts, /etc/netmask, /etc/nodename, /etc/hostname.xyz, /etc/services

Trouble-shooting tools: ping, spray, snoop, traceroute

Three types of installation: Web start, Custom Jumpstart, and Interactive; their strengths and weaknesses.

Web start: minimum system requirements

Custom Jumpstart: sysidcfg file, rules file, and profile files

Interactive: related issues and pitfalls

Function and terminology: share and mount, servers and clients, Remote Procedure Call (RPC)

Setting up an NFS server: temporary and permanent ways.

share –F nfs –o ro=engineering, rw=sales –d "local programs" /export/home

Setting up NFS clients: temporary and permanent ways.

mount –o rw=engineering server:/export/home /home

Start the daemons: /etc/init.d/nfs.server start and /etc/init.d/nfs.client start

NFS file system mount options: rw/ro, hard/soft, suid/nosuid, bg/fg, intr/nointr, retry=n, timeo=n

Automounting NFS with automount

Automount services: /etc/init.d/autofs start or /etc/init.d/autofs stop

Automount maps: master map: /etc/auto_master; direct map: /etc/auto_direct; indirect map: /etc/auto_home

Set up NFS servers and NFS clients

Set up automounter

NIS+: root server, master server, replica server, and client, NIS+ tables,

NIS+ user commands

NIS+ administrator commands

NIS+ domains and objects

Configuring a NIS+ domain: /usr/lib/nis/nisserver, nispopulate, and nisclient

Domain Name Service (DNS): Domain tree, DNS servers, and clients,

Configuring primary name servers, secondary name servers, and caching name servers.

DNS resource records: SOA, NS, A, PTR, MX, CNAME, TXT, RP

Setting up a DNS server and a DNS client

Using NIS+ with DNS: /etc/nsswitch.conf

Set up a NIS+ root master server, master server, replica server

Set up a NIS+ client

Set up a DNS client

Job hunting
