SCSA cram notes for solaris 10 part 1

1. Managing File Systems

Instance name -- the kernel's abbreviated name for every possible device
driver not attached -- means no device at this node or device not in use
config files are under /kernel/drv
path_to_inst file maps instance names to physical device names
kernel uses vfstab and path_to_inst files to find /, /usr and swap partitions at boot time
devfsadm -- creates logical links to device nodes
fragment -- the smallest allocatable unit of disk space

format of vfstab

labelit -- write or display disk labels
fstyp -- full listing of file system parameters
mount -p -- print
tunefs, newfs mounted
fuser -c -k /home
SMC cannot format a disk

2. Installation

Minimum RAM - 128 MB
uname -m -- platform group

Six software groups

Methods of installing

Three phases of installation

pkginfo -- shows info
pkgchk -- checks integrity

zcat -- unzip on the fly
Solaris product registry
patchadd -d -- no backup

3. System boot and shutdown

Openboot -- executes POST and loads boot block
devices called nodes are attached to buses on the device tree

show device commands

stop-n to set nvram defaults
security-mode -- limit users at openboot

bootblock is blocks 1-15 of startup device
ufsboot -- loads OS kernel
sysdef -- lists devices, modules and tunable parameters

boot process

init starts svc.startd

valid service names

svcs -a -- detailed view of service state of all
offline -- means configured but not running or available
svcs -d milestone/multi-user -- show dependencies

4. users and security

eight character usernames, upper, lower and numbers only
must start with letter and must have one lowercase

one primary and 15 secondary groups

SMC can't lock an account or generate password
Password no longer cleared until first login
delete login but deselect home directory

/etc/skel -- Solaris default login init files
UIDs up to 2G

/etc/default/passwd -- default password limits
logins -p -- shows users with no password
/etc/default/login -- set CONSOLE device

aset -- automated security enhancement tool
-l low, medium or high
verifies system file permissions and contents
consistency of passwd and group files
checks environment files
verifies eeprom
ensures can be safely used as network relay

setacl -d -- delete an acl

eeprom -- electronically erasable programable read only memory

5. System Processes

pgrep -l -- long
-f -- full (for matching)

prstat, sdtprocess -- display processes and update at an interval
renice, priocntl -- change priority
renice -n -4 -p 8200
ptree, sdtprocess -- show process ancestry tree

at -l, atq -- show jobs queued up by at

/var/cron/log

must be in /etc/cron.d/cron.allow and not in /etc/cron.d/cron.deny

6. Printing

reject -- prevents queueing
add a local printer -- print manager or lpadmin
default pinter -- $LPDEST, $PRINTER

valid printer ports

cancel -u user
lpadmin -x -- delete printer

print manager
lpstat -p printer
-D description
-T type
-l file types
configuration files -- /etc/printers.conf /etc/lp
lpadmin -p printer -c class
lpstat -p printer -l -- list characteristics
lp -i job name -q 1 -- priorp-.
