The answers are here .......................... !
ans 1) /etc/skel.
ans 2) Mx records.
ans 3) Hard links for files only and soft links are for both directoris and files.
ans 4) in ip base you are running more than one web site on the same server machine,and in name base you have to put more than one DNS record for your IP address in the DNS.
ans 5) in /boot.
ans 6) for example, BIND
ans 7) vc-ligo.tar.gz .
ans 8) copy a file in /etc/sysconfig/network-script/ifcfg-eth0 to ifcfg-eth0:1 .
ans 9) service network reload .
ans 10) Anue systems, makes a Net Tool Optimizer that is used to connect multiple monitoring.
ans 11)you can edit a crontab .
ans 12) its a very long prosedure dude . prosedure of starting of linux os from power on to login prompt..
- BIOS: The Basic Input/Output System is the lowest level interface between the computer and peripherals.
The BIOS performs integrity checks on memory and seeks instructions on the Master Boor Record (MBR) on the floppy drive or hard drive. - The MBR points to the boot loader (GRUB or LILO: Linux boot loader).
- Boot loader (GRUB or LILO) will then ask for the OS label which will identify which kernel to run and where it is located (hard drive and partition specified). The installation process requires to creation/identification of partitions and where to install the OS. GRUB/LILO are also configured during this process. The boot loader then loads the Linux operating system.
- See the YoLincreating a boot disk linux tutorial on for more information on GRUB and LILO and also to learn how to put the MBR and boot loader on a floppy for system recovery.
- The first thing the kernel does is to execute init program. Init is the root/parent of all processes executing on Linux.
- The first processes that init starts is a script /etc/rc.d/rc.sysinit
- Based on the appropriate run-level, scripts are executed to start various processes to run the system and make it functional
ans 13) initrd image is the initial ram disk image While the system getting booted the kernel image will get loaded into the main memory.
ans 14) vmlinuxz.
ans 15) uname -r .
ans 16) from inittab .
ans 17)put the entry in fstab with proper drivers and mount point(/dev/hda10 mount point ext2/3 defaults 0 0).
ans 18)chkconfig.
ans 19)top command and ps -el.
ans 20)rpm -qa nfs and you can check export file in /etc.
ans 21)rpm required dependency software and yum can install automatically with dependancy .
ans 22)The /Prock is a strange beast. It doesn't really exist, yet you can explore it. Its zero-length files are neither binary nor text.
ans 23)home directory is one over which user have complete controland it is its default working directory when its logs in.while the current directory is the users current directorywhich may or may not be his home directory.
ans 24)Linux command has a several parameters or variables that can be use to find out the exit status of command. Please note that these parameters or variables may only be referenced assignment to them is not allowed. You can use $? to find out the exit status of command($ echo $?).
ans 25)we have to recompile the kernal with added fat32 drivers and boot from that kernal.
