Question { IBM, 9989 }

what is cups and how to configure?

Answer

CUPS (formerly an acronym for Common Unix Printing System,
but now with no official expansion) is a modular printing
system for Unix-like computer operating systems which allows
a computer to act as a print server. A computer running CUPS
is a host that can accept print jobs from client computers,
process them, and send them to the appropriate printer.

If you are using a client with CUPS and a CUPS server has
already been configured, installing the printers on your
client can not get much easier than this: do nothing.
Through broadcasting, the client should find the CUPS server
and automatically configure the printers that are installed
on that print server. This is one of the features of CUPS
that will be really appreciated on large networks.

Manually configuring printers with CUPS, also is a peace of
cake. If you are new to CUPS and/or Unix printing, the way
to go is probably the web interface. If you have to
configure lots of printers, using the command-line will
probably be faster.

The URL to access the CUPS web interface is
http://hostname:631/admin by default. The port can be
changed in cupsd.conf if necessary.

To add a printer from the command-line the general syntax is
lpadmin -p printer -E -v device -m ppd Lpadmin with the -p
option adds or modifies a printer. The printers are saved in
the file The -x option deletes the named printer. Read the
lpadmin man page for available options.

Example 3. command-line examples

/usr/sbin/lpadmin -p testpr1 -E -v socket://192.168.1.9 -m
deskjet.ppd
/usr/sbin/lpadmin -p testpr2 -E -v parallel:/dev/lp0 -m
laserjet.ppd
/usr/sbin/lpadmin -x testpr1

More information about configuring printers and options can
be found in the CUPS documentation. The Software
Administrators Manual will teach you all you need to know
about configuring printers with CUPS.

Question { TCS, 8918 }

Please explain the file structure of linux?

Answer

The Linux system contains thousand of files located within
many directories. All directories are organized in a
tree-structure like manner.

* The 'trunk' of the tree is the root directory.
* The root directory is simply identified as a "/".
* All other directories 'branch' off from the trunk.

The following lists the most common directories and their
intended contents.

* / - root directory
* /home - where directories are contained for each user,
example:
* /usr - pronounced 'user' and contains Linux commands
and utilities
o /bin - binary executable programs
o /lib - program libraries, similar to Windows
'dll' files
o /sbin - more executable programs and Linux
utilities for administrative purposes
o /doc - documentation
o /src - source code to programs
* /tmp - temporary work files
* /etc - configuration files
o /rc.d - scripts used during boot and shutdown
process
o /sysconfig - default configuration files
o /sysconfig/network-scripts - network scripts
o /sysconfig/daemons - special programs that run
in background, such as print spooling
* /bin - binary executable programs that all users need
* /dev - device files that control drives, terminals and
any equipment attached to the server
* /var - user specific files
o /log - log files containing system usage and errors
o /spool - where spooled files are stored during
print spooling process
o /mail - where Email files are stored until
retrieved by client Email program
* /proc - system files
* /root - root's home directory
* /opt - other options
* /sbin - more executable programs and utilities

Question { CSC, 14886 }

what is the booting process of linux systen and explain
it,is the first process comes under the installation process.

Answer

As it turns out, there isn’t much to the boot process:
1. A boot loader finds the kernel image on the disk, loads
it into memory, and
starts it.
2. The kernel initializes the devices and its drivers.
3. The kernel mounts the root filesystem.
4. The kernel starts a program called init.
5. init sets the rest of the processes in motion.
6. The last processes that init starts as part of the boot
sequence allow you to
log in.
