ProFTPd on 14.04 - 503 Error

Question

Config file is nice and simple, I'm not asking too much of ProFTPd and I have set required parameters.

    ServerName          “uk.domain.com"
ServerType          standalone
DefaultServer           on

# Port 21 is the standard FTP port.
Port                21

# Umask 022 is a good standard umask to prevent new dirs and files
# from being group and world writable.
Umask               022

# 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 under which the server will run.
User                nobody
Group               nogroup

# To cause every FTP user to be "jailed" (chrooted) into their home
# directory, uncomment this line.
DefaultRoot ~

# Normally, we want files to be overwriteable.
<Directory />
  AllowOverwrite        on
</Directory>

The user has /bin/bash shell set. ProFTPd is in default nobody, nogroup etc. Port TDP and UDP is open on 21, inbound and outbound. Any help would be greatly appreciated!!

There are no directives defined in your configuration. You need to create some directives for Proftp to use. The man page will help with this.

Here's the configuration you're looking for:

## Includes required DSO modules. This is mandatory in proftpd 1.3
# Include /etc/proftpd/modules.conf

# To really apply changes reload proftpd after modifications.
AllowOverwrite on
AuthAliasOnly on
AuthPam on    # Uses unix authentication.

UserAlias userftp connor     # UserAlias *loginuser* *real user*
ServerName                      "uk.domain.com"
