FTP Server Configuration in Redhat Linux
FTP Stands for File Transfer Protocol. FTP is a protocol used to transfer files from one machine to a server. In general most FTP are used for website file uploading in web server through remote login. All web server have the facility of ftp login and ftp file transfer. Most browsers will support ftp connection.
Here we are going to configure ftp server in redhat linux.
Port Number: 20 & 21
Package Name: vsftpd
Service Name: vsftpd
Sever Side Configuration
#yum install vsftpd*
To configure ftp server, do the following changes in vsftpd.conf file
#vim /etc/vsftpd/vsftpd.conf
Line –> 12
anonymous_enable=YES (for download rights)
Line –>27
anon_upload_enable=YES ( for upload)
Line –>31
anon_mkdir_write_enable=YES ( for directory creation)
The Contents uploaded from remote system will be inside this pub directory /var/ftp/pub
#service vsftpd restart
#chkconfig vsftpd on
Change Directory Permission For upload
Files from remote login will be uploaded only inside /var/ftp/pub . Without changing the directory permission we can’t upload the files inside the pub ( /var/ftp/pub) directory
We have to change directory permission for /var/ftp/pub with full rights
#chmod 777 /var/ftp/pub
Client Side
After FTP server configuration, we have to login through client system.
#ftp<space><server IP Address>
#ftp 192.168.1.254
ftp server : ftp or anonymous
password: <enter>

ftp>cd pub

>mget <filename>
>mget abc.txt
Upload
>mput <filename>
>mput abc1.txt
To Create Directory
>mkdir <directory name>
>mkdir user1
To exit
>bye
