mount iso

mount -t -iso9660 -o loop -v <ISO_file>  <mount_point>

step2:

change to mounted dvd path

cd path

ls command will show following files of iso

[root@localhost RHEL6]# ls

[root@localhost RHEL6]#

step 3:  find rpm with following command.

[root@localhost Packages]# ls | grep vsftpd

vsftpd-2.2.2-6.el6_0.1.i686.rpm

[root@localhost Packages]# 

step 4: installing rpm

[root@localhost Packages]# rpm -ivh vsftpd-2.2.2-6.el6_0.1.i686.rpm
warning: vsftpd-2.2.2-6.el6_0.1.i686.rpm: Header V3 RSA/SHA256 Signature, key ID fd431d51: NOKEY

[root@localhost Packages]# 

After installation following files will be created

1) File storing path

[root@localhost ftp]# pwd

/var/ftp

[root@localhost ftp]# ls

pub

[root@localhost ftp]#

2) configuration files 

[root@localhost vsftpd]# pwd

/etc/vsftpd

[root@localhost vsftpd]# ls

ftpusers  user_list  vsftpd.conf  vsftpd_conf_migrate.sh

[root@localhost vsftpd]#

3) Log files:

To check the status of service

[root@localhost vsftpd]# tail -100f /var/log/vsftpd.log

or

[root@localhost vsftpd]# tail -100f /var/log/xferlog

Service start:

[root@localhost log]# service vsftpd

 start

Starting vsftpd for vsftpd:                                [  OK  ]

[root@localhost log]#

Configuration

[root@localhost vsftpd]# vi vsftpd.conf

uncomment following lines

# Allow anonymous FTP? (Beware - allowed by default if you comment this out).

anonymous_enable=YES

#

# Uncomment this to allow local users to log in.

local_enable=YES

#

# Uncomment this to enable any form of FTP write command.

write_enable=YES

# Uncomment this to allow the anonymous FTP user to upload files. This only

# has an effect if the above global write enable is activated. Also, you will

# obviously need to create a directory writable by the FTP user.

anon_upload_enable=YES

#

# Uncomment this if you want the anonymous FTP user to be able to create

# new directories.

anon_mkdir_write_enable=YES

By this it allows ftp user, which created by package. It create system user ftp who does'nt have home directory.By this ftp user can login from any where upload and down files.

Client Configuration

ftp is client version of ftp:

yum install ftp

or

[root@localhost Packages]# ls | grep ftp-0.17-51.1.el6.i686.rpm

ftp-0.17-51.1.el6.i686.rpm

[root@localhost Packages]#

[root@localhost Packages]# rpm -ivh ftp-0.17-51.1.el6.i686.rpm 
warning: ftp-0.17-51.1.el6.i686.rpm: Header V3 RSA/SHA256 Signature, key ID fd431d51: NOKEY

Once client is installed use following commands

root@localhost ~]# ftp 192.168.0.7
