Can't log into ProFTPD set up by Webmin on CentOS - configuration

Question

I just installed ProFTPD on a test CentOS webserver, which contains Webmin.
After installing ProFTPD I tried to connect via FTP and it wouldn't let me. I've tried to connect with FileZilla and terminal on the server. To connect I've tried all the users on the server (root, admin, steven10172) and all of them return the same error "530 Login Incorrect."
Could someone please assist me as to why I can't connect via ftp??

Answer 1

It seems the user is not included in the proftpd users list. Its the default safety procedure with proftd recent versions.
To enable it manually,
In the "Server Status" section of the webmin default page (click 'webmin' to get this page), click on 'ProFTPD FTP Server'. This will open the Proftpd module.
In the "Global Configuration Section", click "Edit Config files"
In the editor find the line umask 22
add the following lines below with the webmin username. this will allow webmin user to use ftp and sftp
umask 22
AllowOverwrite yes
<Limit ALL SITE_CHMOD>
DenyAll
AllowUser webminuser1 webminuser2
</Limit>
save the file and restart proftpd.
**
OR
**
Use the default webmin configuration to enable proftpd for users :
remove and fresh install proftpd.
yum install proftpd
and start the service, service proftpd start
check your ftp connection by telnet. telnet <ipaddress> 21
if telnet connects, Go to webmin menu,
webmin->webmin configuration->webmin modules
In the Install from section, on Standard module from
www.webmin.com, choose proftpd module (you can try just typing in the
box, but its better click the globe icon to select proftpd)
After Selecting Proftpd, check Ignore Dependencies option, and check Grant access to all Webmin users,
And click on Install module button Restart the System for changes to take effect.
Try connecting with ftpclient with the username and password. It should work!

Answer 2

In webmin, go to your ProFTPD module and look for an icon/option of Denied FTP Users.
Remove any users from that list, that you want access to the FTP server. One spot I had trouble with.

Answer 3

In most of the ftp clients by default its enabling FTP Passive connection option so just unselect it and then try to connect.

Answer 4

While this only helps for one or two of the usernames you specified, root accounts are generally barred from FTP access.
... a list of the users that either have no business using ftp or
have too many privileges to be allowed to log in through the FTP
server daemon. Such users usually include root, daemon, bin, uucp,
and news.
