Testing FTP server :

To connect with FTP server from any client machine follow the steps:

First time when you try to connect with ftp server the connection will refuse by the server because the vsftpd services is by default stopped, so restart all the services,

Step-1:  Test the ftp connection

[root@client ~]# ftp 210.207.201.7

ftp: connect: Connection refused

ftp>

Now quit from ftp connecting shell by using “bye” command & restart all the required services

Step-2: Testing the status of vsftpd:

You can test the vsftpd process is running or not by using “netstat –a” command:

[root@ftp ~]# netstat –a | grep ftp

Or you can also use the following command to test that ftp is running or not. If not running then restart all the services.

[root@ftp ~]# service vsftpd status

[root@ftp ~]# service iptables stop

[root@ftp ~]# service network restart

[root@ftp ~]# chkconfig vsftpd on

[root@ftp ~]# service vsftpd restart
