pkgchk -d SMSmon -l  SMSmon

What package owns file X

Basics

Nice big PS

/usr/ucb/ps -elf

compile man page index, the windex db:

/usr/bin/catman -w

Interfaces

Interface unvwmare: use e1000 devices, it works why not vxnet3?

create hostname file

/etc/hostname.e1000g0

externalname.domain.com

/etc/hostname.e1000g0

internalname.domain.com

plumb bum!

ifconfig e1000g0 plumb
ifconfig e1000g0 plumb

Watching the machine start

at the ok prompt:

boot -m verbose

Packages of note

SUNW:

SUNWdoc
SUNWman

Getting sshd setup from a core build:

pkgadd -d . SUNWsshcu SUNWsshdr SUNWsshdu SUNWsshr SUNWsshu

system      SUNWsshcu                        SSH Common, (Usr)
system      SUNWsshdr                        SSH Server, (Root)

system      SUNWsshu                         SSH Client and utilities, (Usr)

create host keys:

/lib/svc/method/sshd -c

enable service:

svcadm enable network/ssh:default

show volume iostat

zfs list

show performance arc -h

hidden dirs:

.zfs
.zfs/.snapshots
.zfs/.snapshots/ALL THE SNAPSHOTS

controlling access to snap shot dirs:

zfs set snapdir=visible tank/home/administrator

To hide the .zfs folder:

Nexenta

interfaces : nmc (comnad line) and nmv ( web interface)

shares are called folders.

block size : use default 128k good for many apps. possible to change blocks size on the fly.

in the nmc get a bash shell for OS access:

options expert_mode=1
!bash

show appliance syslog

snapmirror nexenta style:

setup auto-sync create -g

Setting you manpath

look at all the man paths:

[root@alpha-ldap-01 log]# grep "man d " /var/sadm/install/contents | awk '{print $1}'
/opt/csw/share/man
/usr/local/apache2/doc/apache2/docs/man
/usr/local/apache2/man
/usr/local/doc/openldap/doc/man
/usr/local/man
/usr/local/mysql/man
/usr/local/mysql/share/mysql/german
/usr/local/php/man
/usr/local/share/man
/usr/local/ssl/man
/usr/sfw/share/man
/usr/share/man
[root@alpha-ldap-01 log

make a new line for your profile:

grep "man d " /var/sadm/install/contents | \
awk 'BEGIN{ORS=":"}{print $1}' | \
awk '{print "setenv MANPATH=" substr($0, 0, length($0)-1 ) }' >> ~/.profile

run after installing new software. NOT PERFECT, system wide?

Service Administration

Solaris now uses SMF Service Management Facility. Here is a wonderful cheatsheet:

Sendmail

from: http://thegreyblog.blogspot.ca/2009/11/configuring-sendmail-on-solaris-10.html

svccfg -s svc:/network/smtp:sendmail listprop

/lib/svc/method/smtp-sendmail

local=`/usr/bin/svcprop -p config/local_only $SMF_FMRI 2>/dev/null`
if [ $? = 0 -a "$local" = "true" ]; then
 OPTIONS="$OPTIONS -C /etc/mail/local.cf"
