==Server configuration==

Now you have to configure your server. You have to find specified lines and change or '''uncomment''' them. For an easier way to find specific lines, you can press “'''CTRL+W'''” and it will show where the line is. <br />
Lines that has to match with an example:<br />
Uncomment the “'''write_enable=YES'''”, “'''ascii_upload_enable=YES'''” and “'''ascii_download_enable=YES'''” lines and make sure that the value of them is “'''YES'''”

Scroll a little bit down and and find the section as shown in an example below. <br />

Change the “chroot” settings
Add the following lines:<br />
'''user_sub_token=$USER'''<br />
'''chroot_local_user=YES'''<br />
'''chroot_list_enable=YES'''<br />
Change the default “'''chroot'''” settings. Add the following lines:<br />
'''chroot_list_file=/etc/vsftpd.chroot_list'''<br />
'''local_root=home/$USER/Public_html'''<br />
'''''*If any of these lines already exist, remove the “#” before each line.<br />'''''
Uncomment “'''ls_recurse_enable=YES'''” line and make sure that the value is “'''YES'''”<br />

Save your list by pressing “'''CTRL+X'''”, typing “''y''” and pressing “'''Enter'''” button on your keyboard.<br />

Restart VSFTPD by running “'''sudo service vsftpd restart'''”.

=Accessing your server=

==In Ubuntu terminal==

You can test server accessing with different users, which you entered before to the “'''vsftpd.chroot_list'''”.<br />
You have to check your server’s IP address by running command “'''ifconfig'''”. 
Your “'''inet addr'''” is your server’s IP address. (for example '''192.168.10.10''')

You can simply access your FTP server by runing “'''ftp localhost'''” command.
For example, the user “'''test2'''” is in the “'''vsftpd.chroot_list'''” file. But user “'''test'''” is not, so login failed.

If you want to close server, just type “'''bye'''”.

==Using FileZilla==

Install FileZilla by typing “'''sudo apt-get install filezilla'''” in your Ubuntu terminal.<br />

Run Filezilla by typing “'''filezilla'''” in terminal.<br />

This window appears:
