FTP server only root can log in no one else ? vsftp slackware


Hello everyone. It was pretty easy to setup the vsftpd server. Then i started it with "vsftpd &" when i type "vsftpd" it will just hang and i have to hit ctrl-c. To stop it i killall vsftpd.

But the only user that can log in is root, no one else can. I made a group called "ftpusr" they can log in via ssh but not ftp.

How do i make it so a user can ONLY log in via ftp and ONLY work in one folder. I want them to have read/write access to one folder on my webserver.

I dont get why only root can log into ftp but the other "testuser" cannot but he can log on via ssh?

this is my vsftpd.conf file

Code:
# 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=YES
#
# 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
anon_root=/var/ftp
#
# 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=NO
#chown_username=zonemikel
#
# 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 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..
#ascii_upload_enable=YES
#ascii_download_enable=YES
#
# You may fully customise the login banner string:
ftpd_banner=Welcome to 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
# To run vsftpd in standalone mode (rather than through inetd), uncomment
# the line below.
listen=YES

Let us go step by step.
1. stop vsftpd
# service vsftpd stop
2. Create a user so that this user and only this user can login in a paricular directory with rw permission and also can't see anything else.
# useradd -d /usr/local/apache2/htdocs/Dir_name username
# passwd username
# chown -R username /usr/local/apache2/htdocs/Dir_name

3. Now have to configure vsftpd.conf"

As far my knowledge by def. root access to ftp is disabled. Anyway activate the chroot options and create that file (vsftpd.chroot_list) as specified in /etc and put the username there to jail him in that directory only.

PHP Code:
# 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.

local_enable=YES
#

xferlog_std_format=YES
#
# You may change the default value for timing out an idle session.
#idle_session_timeout=600

# 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 
Start vsftpd now and now will be prompted for username and password.

Hope this works & if found any better solution then please post here for us.

I will try that. I had actually just given up and used sftp over the ssh.

The dir for my webserver is on a mounted drive. When i added the user and put his "home" dir as one of my webserver directories it screwed up all of my webpages, i had to go and reset all the permissions.

I will try your information later, but i know service vsftpd stop does not work, least not on slackware.

also if i do this
chroot_list_file=/etc/vsftpd.chroot_list

wont i have to make that file (it does not exist) and what do i put in it?

Yes, you have to create that file to jail that user in that specified directory and just put ftp user name in that file.
