VSFTP Connection Refused Error

[Denda]

Hi All -
I have a Red Hat Enterprise server built. I'm going to use it as a ftp server in our DMZ. While building the system internally, vsftp worked great, once I had everything set up, I then changed my ip's and put it in our DMZ. As soon as I did that, the following is happening.

1) unable to ftp localhost -> gives connection refused error
2) vsftpd will not stop via service vsftpd stop, it gives a failed message
3) vsftpd will start via service vsftpd start, but ps -ef|grep vsftpd brings up nothing.. So the process is not actually starting from what I can tell
4) vsftpd is not writing to /var/log/vsftpd
5) /var/log/message just shows vsftpd started successfully & vsftpd stop failed....

HELP!! Thank you all for your time.

The only references I'm seeing in secure are the following:

sshd:received signal 15: TERMINATING
sshd:server listening on 0.0.0.0 port 22

what is the content of /etc/vsftpd/vsftpd.conf as well as
/etc/vsftpd.ftpusers and /etc/vsftpd.user_list?

vsftpd.conf
# Example config file /etc/vsftpd.conf
#
# The default compiled in settings are fairly paranoid. This sample file
# loosens things up a bit, to make the ftp daemon more usable.
# Please see vsftpd.conf.5 for all compiled in defaults.
#
# READ THIS: This example file is NOT an exhaustive list of vsftpd options.
# Please read the vsftpd.conf.5 manual page to get a full idea of vsftpd's
# capabilities.
#
# Allow anonymous FTP? (Beware - allowed by default if you comment this out).
anonymous_enable=NO
#
# Uncomment this to allow local users to log in.
local_enable=YES
#
# Uncomment this to enable any form of FTP write command.
write_enable=YES
#
# Default umask for local users is 077. You may wish to change this to 022,
# if your users expect that (022 is used by most other ftpd's)
local_umask=022
#
# Uncomment this to allow the anonymous FTP user to upload files. This only
# has an effect if the above global write enable is activated. Also, you will
# obviously need to create a directory writable by the FTP user.
#anon_upload_enable=YES
#
# Uncomment this if you want the anonymous FTP user to be able to create
# new directories.
#anon_mkdir_write_enable=YES
#
# Activate directory messages - messages given to remote users when they
# go into a certain directory.
dirmessage_enable=YES

# Activate logging of uploads/downloads.

#
# If you want, you can arrange for uploaded anonymous files to be owned by

#
# You may override where the log file goes if you like. The default is shown
# below.

# ftp server can use as a totally isolated and unprivileged user.
#nopriv_user=ftpsecure
#
# Enable this and the server will recognise asynchronous ABOR requests. Not
# recommended for security (the code is non-trivial). Not enabling it,
# however, may confuse older FTP clients.
#async_abor_enable=YES
#
# By default the server will pretend to allow ASCII mode but in fact ignore
# the request. Turn on the below options to have the server actually do ASCII
# mangling on files when in ASCII mode.
# Beware that turning on ascii_download_enable enables malicious remote parties
# to consume your I/O resources, by issuing the command "SIZE /big/file" in
# ASCII mode.
# These ASCII options are split into upload and download because you may wish
# to enable ASCII uploads (to prevent uploaded scripts etc. from breaking),
# without the DoS risk of SIZE and ASCII downloads. ASCII mangling should be
# on the client anyway..

ftpd_banner=This is a private system operated by and for XXX Company, LLC. Authorization from XXX Company management is required to use this system. Use by unauthorized persons is prohibited.

# You may specify an explicit list of local users to chroot() to their home

chroot_list_file=/etc/vsftpd.chroot_list
#
# You may activate the "-R" option to the builtin ls. This is disabled by

See what happens if you set anonymous_enable=YES, also check the var/log/messages after you attempt to connect. Do you actually have a /etc/vsftpd.chroot_list file? Make sure you restart vsftpd if you change the vsftpd.conf file.

ARGH!! OK - been out sick with the crud for a few days, just getting back to this now... I can no longer log into the server via a local user... I get the 530 error, login incorrect. This user worked fine for me previously. I've read around that it may have something to do with a file called vsftpd.pam that needs to be copied over to pam.d and renamed to ftp. Could that be the issue? If so, I installed vsftpd at the same time as red hat and there is no vsftpd.pam file anywhere on the server. Is it within the vsftpd rpm on the cd's? Or am I barking up the wrong tree again...

login via ftp via a local user. sorry I didn't specify

Ok - got the stupid local users working again... Back to the connect :unknown error number
