Vsftpd problems
 
Hey,

I am just setting up an ftp server with Fedora Core 5 and vsftpd and I have run into a few things I am unsure of.

1. Anyone can log in anonymously but can't really do anything...it shows a pub folder and an uploads folder but I have no clue where these are on the drive. When I turn the anonymous login off it won't start the service...says failed.

I am trying to just have it for 1 person...so the one user name on my computer is Kaltrop....I would like for it to only allow this user to login with password and keep him in the home dir....I can login with him but navigate the whole computer with it...I turned the chroot on but then it doesn't recognize him as a user...won't let me login. One of the other posts mentioned that there might be 2 conf files in the drive....I can see a couple when I browse the vsftpd folder on the ftp but I can't see them on the server to delete them.

Here is the vsftpd.conf file contents

# Example config file /etc/vsftpd/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.
xferlog_enable=YES
#
# Make sure PORT transfer connections originate from port 20 (ftp-data).
connect_from_port_20=YES
#
# If you want, you can arrange for uploaded anonymous files to be owned by
# a different user. Note! Using "root" for uploaded files is not
# recommended!
chown_uploads=YES
chown_username=Kaltrop
#
# You may override where the log file goes if you like. The default is shown
# below.
#xferlog_file=/var/log/vsftpd.log
#
# If you want, you can have your log file in standard ftpd xferlog format
xferlog_std_format=YES
#
# You may change the default value for timing out an idle session.
idle_session_timeout=600
#
# You may change the default value for timing out a data connection.
data_connection_timeout=120
#
# It is recommended that you define on your system a unique user which the
# 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 on some FTP servers, ASCII support allows a denial of service
# attack (DoS) via the command "SIZE /big/file" in ASCII mode. vsftpd
# predicted this attack and has always been safe, reporting the size of the
# raw file.
# ASCII mangling is a horrible feature of the protocol.
ascii_upload_enable=YES
ascii_download_enable=YES
#
# You may fully customise the login banner string:
ftpd_banner=Welcome to Kaltrop FTP service.
#
# You may specify a file of disallowed anonymous e-mail addresses. Apparently
# useful for combatting certain DoS attacks.
#deny_email_enable=YES
# (default follows)
#banned_email_file=/etc/vsftpd/banned_emails
#
# You may specify an explicit list of local users to chroot() to their home
# directory. If chroot_local_user is YES, then this list becomes a list of
# users to NOT chroot().
#chroot_list_enable=YES
# (default follows)
#chroot_list_file=/etc/vsftpd/chroot_list
#
# You may activate the "-R" option to the builtin ls. This is disabled by
# default to avoid remote users being able to cause excessive I/O on large
# sites. However, some broken FTP clients such as "ncftp" and "mirror" assume
# the presence of the "-R" option, so there is a strong case for enabling it.
ls_recurse_enable=YES
pam_service_name=vsftpd
userlist_enable=YES
#enable for standalone mode
listen=YES
tcp_wrappers=YES



Thanks for any help you can give

1) Please don't bump your own post within 24 hours - it is against the rule. This is to allow everyone around the world to see your post.

2) If you are only setting it up for one user - ie you don't require anonymous logins, then a more secure solution is SSH. SSH also has SFTP and SCP which allow file transfer. SSH is more secure than FTP (and telnet), because SSH encrypts all data, while FTP and telnet send everything as plain text (including passwords).

I suggest that you install a SSH server (OpenSSH) on your system. Allow connections on Port 22 through your firewall, and you should be able to connect. Fedora Core 5 already comes with OpenSSH, but you may need to install it. I have some information on SSH and SFTP here.

It is possible to get Chroot working with SSH, but I don't know how :)

I hope this helps

The below link will probably provide sufficient info to setup vsftpd daemon.

According to info that I found on the net (possibly outdated), it's not straight forward. So for me, vsftpd solution is a lot easier.
