Solaris Admin Interview Questions

ifconfig qe0:1 10.10.1.150 netmask 255.255.255.0 broadcast + up

USE CMD ifconfig qe0 addiff 10.10.1.150 up

#more /etc/default/nfs command is verified. it provides the version number of NFS

#netstat|grep Version

prtconf -vp|grep -i boot ----gives last booted device

who -b -------last booted time

eeprom boot-device----------gives boot device

df -h

/dev/dsk-block device /dev/rdsk -raw device

In /dev/rdsk if the data which is written did not used full 512bytes of a sector then for the next time we cannot use the left space.

where as /dev/dsk maintains a buffer memory from where the data is copied to disk so there is no loss of space.

I hope I understood this way:

raw disk device /dev/rdsk is using for system management/administration
block disk device /dev/dsk is using for I/O operations

#vi /etc/default/login
# CONSOLE=/dev/console (Only root can login)

CONSOLE=/dev/console (normal user can login and after that can do switch as root but directly root cant login from remote)

open, #vi /etc/default/profile

go to 18th line, and comment the line CONSOLE=/dev/console to: #CONSOLE=/dev/console

Now you can do telnet to remote pc as Root admin

Two way can do
1)#kbd -a (for enable|disable)
or
2)#Vi /etc/default/kbd
KEYBOARD_ABORT=disable

For temprary basis type command disable stop+Akbd -a disable
For permanent basis vi/etc/default/kb and edit keyboard_abort diable

3.d# Disk number -- always d0 for SCSI disks.
4.s# Slice number

in sparc system we can create only 7 slice bt in x86 is same as sparc 8th and 9th slice for boot loader files

 Whole disk size can be the maximum size of a slice as usually slice 2 will be the whole disk partition in Solaris 10.

Logical device path i.e., /dev/dsk/c#t#d#s#
