Solaris 10 HANDBOOK

• admintools is not implemented
• pkgchk -P instead of grep /var/sadm/install/contents
• RBAC: Role-Based access control (kind of built in sudo)

On Solaris using the shutdown command to reboot, halt or power off your server is the best option, because this command will call the rc script.

shutdown -i6 -g60 -y

-i : init level
-g : grace time (60 secondes in this case)
-y : Pre-answer yes

shutdown -i0 -g60 -y

shutdown -i5 -g60 -y

You will have to boot the system with «kadb».

# eeprom boot-file=kadb
# reboot

OR

root (hd0,0,a)
kernel /platform/i86pc/multiboot kadb
module /platform/i86pc/boot_archive

From a directly attached keyboard or serial port connection, type:

 F1-A - press the "F1" and "A" keys, simultaneously. 

You can test it to make sure it’s work and then just enter:

:c

to return to the normal mode.

The control-alt-d key sequence also works.

Once at the kadb prompt, type:

$<systemdump

This will generate a core file, which can be retrieved from:

 /var/crash/'uname -n' (or wherever the local system stores core files)

How to determine whether a system has 32-bit or 64-bit solaris capablilities enabled

# isainfo -v
32-bit sparc applications

Isalist prints the names of the native instruction sets executable on this platform on the standard output

# isalist 
sparcv8 sparcv8-fsmuld sparcv7 sparc

# psrinfo -v
Status of processor 0 as of: 01/24/07 13:03:35
  Processor has been on-line since 01/19/07 14:13:09.
  The sparc processor operates at 60 MHz,
        and has a sparc floating point processor.

if [ "`psrinfo -s 3 2> /dev/null`" -eq 1 ]
     then
          echo "processor 3 is up"
     fi

Now before getting into the details of how to configure Solaris for root logins, keep in mind that this is VERY BAD security. Make sure that you NEVER configure your production servers for this type of login.

Simply edit the file /etc/default/login and comment out the following line as follows:

# If CONSOLE is set, root can only login on that device.
# Comment this line out to allow remote login by root.
#
# CONSOLE=/dev/console

First remove the ‘root’ line from /etc/ftpusers.
Also, don’t forget to edit the file /etc/ftpaccess and comment out the ‘deny-uid’ and ‘deny-gid’ lines. If the file doesn’t exist, there is no need to create it.

NOTE: If you are using Solaris 9 or Solaris 10, the ftp* files are located in /etc/ftpd

/etc/TIMEZONE

• set the domain name

domainname nis.domaine.com

• edit /etc/hosts

#
# Internet host table
#
127.0.0.1       localhost

# NIS 
192.168.1.100 nis1.domain.com
192.168.1.101 nis2.domain.com

• ypinit

ypinit -c

In this example I’m trying to install the package «SUNWbash» but it could be any package, you may have been through those different cases:

# pkgadd SUNWbash                                        
pkgadd: ERROR: no packages were found in </var/spool/pkg> 
 
# pkgadd ./SUNWbash                                        
pkgadd: ERROR: no packages were found in </var/spool/pkg> 
 
# pkgadd /mnt/Solaris_10/Product/SUNWbash       
pkgadd: ERROR: no packages were found in </var/spool/pkg>
 
# pkgadd -d ./SUNWbash
pkgadd: ERROR: no packages were found in </mnt/Solaris_10/Product/SUNWbash>

In the three first cases «pkgadd» looks in the default folder «/var/spool/pkg» in order to find packages and install them but none is found. In the fourth case the package himself is defined as a folder containing packages, that’s why it fails.
The right solution is:

# pkgadd -d /mnt/Solaris_10/Product/ SUNWbash
or 
# pkgadd -d $PWD SUNWbash

Thus pkgadd will consider «/mnt/Solaris_10/Product/» as default folder and «SUNWbash» as package to install.
