Mounting Linux file systems

Files under Linux, Operating System | 1 Comment | 252 views

After talking on the Linux File Types in the previous entries, is time to learn the basic on mounting linux file systems. For the data contained on hard disks, disk partitions, network drives, and removable media to be accessed under Linux, it is necessary to attach – or mount – the devices containing the data to the Linux directory structure. The reason for this is that Linux treats every device or partition as a separate and independent file system. It also views all data as though it were in a subdirectory of the root (/) directory, regardless of the kind of device on which it is stored – even when it is kept on a separate computer.

disk drive

It is an important part of the role of the Linux system administrator to ensure that file systems are mounted correctly, whether at boot time or manually, to ensure that all required data is available at the expected locations.

Advantages of mounting Linux file systems and devices

Devices are mounted at predetermined directories below the root file system. These are usually, although not always, special directories created for the purpose. The file systems that belong under the /var, /home, and /usr directories, for example, are kept on separate partitions or devices from the root file system. Network machines are frequently configured so that the /home data for all machines is actually stored on a single Network File System (NFS) server, which is then mounted under the /home directory on each individual machine. This enables users to access their own home directories in the usual locations, regardless of which computers they are actually logged on at. (more…)

I still remember about 15 years ago, people using big size cell phone,  as time goes by, the cell phone design to become smaller and smaller, but few years back, cell phone again design to become bigger size again due to require bigger LCD display screen.

SLR Camera

Trend always change time by time; long time ago when Digital Camera introduce to the world, the size are consider big, with using Compact Flash (CF) card and Smart Media card (SM); as time goes by, the size design to become smaller, and using Secure Digital Card (SD). Again, within this few years, Digital Single Lens Reflect (DSLR) camera has became cheaper and cheaper, and most of the people afford to own it.

Basic Networking Terminology

Files under Cisco, Networking | 3 Comments | 231 views

Computer networking, like most industries, has its own jargon, which includes technical terms, abbreviations, and acronyms. Without a good grasp of the terminology, it will be difficult to understand the concepts and processes involved in networking. The following list of terms and their definitions is intended to be a quick reference that defines some of the most important words, phrases, and acronyms related to computer networking:

computer networking

  • A network interface card (NIC), pronounced “nick,” is also called the LAN adapter, or just the network interface. This card typically goes into an ISA, PCI, or PCMCIA (PC card) slot in a computer and connects to the network medium. It then connects to other computers through the network media.
  • Media refers to the various physical environments through which transmission signals pass. Common network media include twisted-pair, coaxial, and fiber-optic cable, and even the earth’s atmosphere through which wireless transmission occurs.
  • A protocol is a set of rules. In the case of a network protocol, it is a set of rules by which computers communicate. The term “protocol suite” describes a set of several protocols that perform different functions related to different aspects of the communication process.
  • Cisco IOS software which runs on Cisco equipment and devices, is the industry-leading and most widely deployed network system software. It delivers intelligent network services for enabling the rapid deployment of Internet applications.

Cisco IOS software provides a wide range of functionality, from basic connectivity, security, and network management to technically advanced services. The functionality of Cisco IOS software is the result of a technological evolution. First-generation networking devices could only store and forward data packets. (more…)

Do your blog able to bring influence to society?

All the while, we do have same dissatisfy with certain party, complaint on certain product and services, disagree with the decision that some authority made. but does out dissatisfy, complain, and disagree really bring the thing better?

Like my case, I do not satisfy with my apartment’s management, because they never do their job, but does complain really help?

Yesterday when I come back from the mainland, the road to town (so call jelutong “highway“) was fcuking JAM from the bridge. Stuck there about 45 minute only know what happen in front. Is because of our CEPAT, MESRA dan BETUL are “hardworking” doing blocking at there. We don’t what they blocking for, citizen are very dissatisfy with their “CEPAT, MESRA dan BETUL” and what can we do?

mesra cepat betul

Same case during Chinese New Year, during the PEAK hour, they blocking the road in front of CHUNG LING HIGH SCHOOL, and make the traffic JAM along the Air Itam road and from FALIM. With their “hardworking“, bring suffer to the citizen. What can we do?

A lot cases that happening on me which I does not have the power make it better, just like I for to buy XMAS present to the legal thief and I get a summon from ‘CEPAT, MESRA dan BETUL when I parking at a legal parking area few year back.

If I am a blogger whom can bring influence to the society, I really want to represent all the citizen voice out our dissatisfaction on the blog. Not to said ANTI certain party, just would like to take back out RIGHT and hope to makes thing better.

Linux files types

Files under Linux, Operating System | 6 Comments | 457 views

Recently I come across some linux command during I login to my customer site to retrieve activity log file, and also studies some of the linux file types, and simple command to know what is the file types at Linux Operating System.

Linux uses four basic file types:

linux file types

  • ordinary files
  • directories
  • symbolic links
  • block and character device files

You determine a file’s type by issuing the ls -l command and reading the first character of each row of the output.
The typical output of the ls command is as follows:

$ ls –l
total 8
-rw-r–r–     1 root   root       22 Oct  6 15:33 anormalfile
brw-rw—-     2 root   disk  41,   0 May  5 1998 blockdev
crw-rw-rw-     2 root   root   5,   0 May  5 1998 characterdev
drwxr-xr-x     2 root   root     4096 Oct  6 15:33 subdir
lrwxrwxrwx     1 root   root       11 Oct  6 15:35 symbolic -> anormalfile

Ordinary files begin with a dash (-), directories begin with d, symbolic links begin with the character l, block devices are prefaced with the character b, and character devices begin with the letter c. (more…)
