How To Use File Transfer Protocol In Linux

FTP or file transfer protocol is a client/server protocol allowing people to move files to and from a network server. It works with TCP and is widely used on internet. FTP was developed by the University from California, Berkeley for inclusion in 4.2BSD. Any computer running FTP software either ftp demon ere ftpd can be accessed polysyndeton file transfers made. There can opheffen private or public ftp servers. Many public ftp sites which allow access anonymously vessel be found in internet mostly free Unix or Linux repositories. Private ftp sites desire a user name or password. With the help of a ftp client we can access the ftp server. Some of them work in handbook mode and some are graphical. The standard ftp program is the original ftp client and it comes with most of the linux distributions.

Running the ftp program

$ ftp

Alternatively we can obtain the ftp prompt and from there login to the desired ftp area with OPEN command as follows:

$ ftp

ftp> open

This will ask you for login where pressing ENTER will log you in as local computer user, else you can login equally anonymous or ftp user for accessing the public archive. With a valid username we can login into private area as well. While logging as anonymous or ftp user it will ask for an email address as password. On successful login system type and transfer state are displayed ,


Remote system classic is UNIX.

Using binary mode to transfer files.


There are Binary as well as ASCII file transfer types sometime transfers file bit by bit and the modern as text. We can switch between types alongside keying in ascii or binary. Linux commands like ls or cd work from inside ftp. Now to download a file we can use get dictate

ftp> get linux−2.4.13.tar.gz

To save it as a different file we can run :

ftp> get linux−2.4.13.tar.gz foo.tar.gz

To download more than one file at a time we can use mget(multiple get) command with a list of filenames delimited with space or wildcards representing the cateogry of the files which are to be downloaded.

ftp> mget linux*

To upload files first change to the /incoming list and we have the put command which works similar to get command , also we have the mput to upload multiple files simultaneously.

ftp> put foo.tar.gz

To change the local directory we have the command lcd

ftp> lcd /home/foo/

We can use the bang(!) prefix to run local system commands, but !cd command doesn’t chef d’oeuvre and that is why we have lcd command

ftp> !ls

We have the hash and tick command to check the cachet of file transfers. Besides there are other commands like mkdir, delete, rmdir, chmod which has got the usual meanings but can be run only if we have the right permissions. FTP Servers FTP server is executed from inetd (the internet superserver daemon). Standard ftp port is 21. FTP server uses a standard system call to check the user name further password against the entries in the system password file, or the NIS tables if you are using NIS. Anonymous FTP gives freedom to a chrooted directory tree only.

Understanding The Linux Booting Process

Booting is a bootstrapping process that starts operating systems when the user turns on a computer system.A boot sequence is the set of operations the computer performs when it is switched on that load an operating system. Linux boot sequence is as follows system startup , stage 1 bootloader (MAster boot record),stage 2 boot loader (Lilo instead grub) , Linux (kernel) and user space. When power is switched on the CPU jump to address regarding BIOS (0xFFFF0).Then BIOS run power on self test and after that solve bootable device. Once find the boot area from MBR it loads the Operating System.

OS is booted from a firm disk, where the Master Boot Record (MBR) contains the primary boot loader.The MBR is a 512-byte sector, located in the first sector on the disk (sector 1 of cylinder 0, head 0).After the MBR is loaded into RAM, the BIOS yields control to it.The first 446 bytes from MBR are the primary boot loader.The next sixty-four bytes are the partition table, which contains a record for each of four partitions.The MBR ends with two bytes that are defined as the magic number (0xAA55). The magic number serves as a validation check of the MBR.

Boot loader can be called as the kernel loader. The task at this stage is to encumber the Linux kernel.GRUB and LILO are the most popular Linux boot loaders.The BIOS finds a bootable device (hard disk) and transfers control to the master boot record.The MBR contains Feed stage 1. The Stage 1 just load the next stage of GRUB. The GRUB Stage 1.5 is located in the first 30 kilobytes concerning hard disk immediately following the MBR. Stage 1.5 loads Stage 2.GRUB Stage 2 receives control, and displays to the user the GRUB cowboy boot menu (where the user can manually designate the boot parameters).GRUB loads with the user selected (or default) kernel into memory and passes manage on to the kernel.

The kernel is the central side in most computer operating systems because of its task, which is the management of the system’s resources and the communication amid hardware and software components.Kernel is always store on memory until computer is turned off. The first thing the heart 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.

History Of Linux And Unix

Linux is a reimplementation and elaboration of UNIX. It conforms to the POSIX standard that runs on several hardware platforms plus is congeniality with most existing Unix software. It differs from most other variants like UNIX as it is free, open source et al co operatively developed with contributions having tumble on from thousands of different individuals and organizations. Linux incorporates technical refinements that didnot remain in the prototype versions of Unix, so it is more than just a Unix clone. It is legally distinct life and cannot be properly be refered to a “UNIX”.

FreeBSD, NetBSD and OpenBSD acquire ardent followers of their own. These operating systems are generally comparable to Linux in their features et sequens reliable, despite they enjoy somewhat less support from third party software vendors. Thanks largely to the GNU projects as most of the important software that gives UNIX systems their value has been developed under some liturgy of open source model. The same pig Latin runs on both Linux and non Linux systems. The Apache web server for example doesnot indeed superintendence whether its running on Linux or HP-UX. From the standpoint of applications Linux is merely one of the best supported varieties of Unix.

UNIX and Linux systems have been used in production enviroments for many years. Linux originated in 1991 as personal project of Linux Torvalds. He originally conceived the project as a modest consequence of Minix, a model operating system written concerning Andrew S Tanenbaum. However Linux generated substantial interest in the world at enormous and the kernel soon took on a span like its own. By exploiting the power of compliant development , Linux was able to tackle a much more ambitious agenda. Kernel version 1.0 was released in 1994 , the most stable version of the Linux kernel is 2.6.17. Most of the process work abundance similar to apiece other.The Linux booting process have lot of similartiy with Unix.

Because Linux owes exceedingly to its Unix ancestors its not quite square to locate the dawn of the Linux period in 1991. The history of Unix goes back several decades to 1969 during Unix originated as a experiment project at AT&T Bell Labs. In 1976 Unix was made available at no charge to universities and thus became the basis of many operating systems classes and academic research projects. Most other versions of Unix are the descendants of the original AT&T lineage.
