Hi,
I use ProFTPd for all my virtual servers. And accessing has never been a problem.
I even used it to share files with other people all over the world.
For some reason all access from outside my LAN is denied recently.
I haven’t changed anything (Don’t change anything if it’s not broken)…
After a lot of searching on the web, all i could find was opening up ports for passive connections and using MasqueradeAddress . So i added those lines in the config file and opened up the ports in my router.
It gives me a 530 error (access denied).
When trying to log in using an FTP client it shows me the connection with the server is established, but as soon as the login credentials are checked, it returns the error.
Is there anyone with knowledge to assist me with this one?
My config file is below.
#
# /etc/proftpd/proftpd.conf -- This is a basic ProFTPD configuration file.
# To really apply changes, reload proftpd after modifications, if
# it runs in daemon mode. It is not required in inetd/xinetd mode.

In some cases you have to specify passive ports range to by-pass
firewall limitations. Ephemeral ports can be used for that, but
feel free to use a more narrow range.
PassivePorts 60000 60100
If your host was NATted, this option is useful in order to
allow passive tranfers to work. You have to use your public
address and opening the passive ports used on your firewall as well.
MasqueradeAddress xxx.xxx.xxx.xxx
This is useful for masquerading address with dynamic IPs:
refresh any configured MasqueradeAddress directives every 8 hours
DynMasqRefresh 28800
To prevent DoS attacks, set the maximum number of child processes
to 30. If you need to allow more than 30 concurrent connections
at once, simply increase this value. Note that this ONLY works
in standalone mode, in inetd mode you should use an inetd server
that allows you to limit maximum number of processes per service
(such as xinetd)
MaxInstances 30
Set the user and group that the server normally runs at.

In order to keep log file dates consistent after chroot, use timezone info
from /etc/localtime. If this is not set, and proftpd is configured to
chroot (e.g. DefaultRoot or ), it will use the non-daylight
savings timezone regardless of whether DST is in effect.
