Article: vsftpd on Suse Linux pro »

FERDY CHRISTANT - AUG 23, 2005 (05:49:57 PM)

This week my holiday started, for 3 weeks I will not have to work. Next week I will have my actual holiday in Ireland with 3 friends, the other two weeks I'll mostly spend relaxing and catching up with things.

Today's follow-up activity is on setting up a vsftpd (Very Secure FTP Daemon) server on my new Suse installation. The Suse website claims this is a 5 minute job, because the package comes installed with Suse 9.3. All I was supposed to do is edit one config file.

Not for me. In the end I spend an entire day getting it to work exactly the way I want it to. Partly because I'm a Linux n00b, partly because the specifics of setting up my installation were not in the basic instructions from Novell. After my 19th nervous breakdown, I have what I want. Looking back at the process, it is still not intuitive to me. That's why I'll list my steps in this mini article, so I can remember it next time I have to do this. Maybe it is of use to you as well.

Goal

vsftpd promises security and performance, and is well recommended by the Linux community. Not wishing to argue with that, I decided this would be the package I need. The setup I want is simple:

  • The FTP server must be accessible from both my Linux and Windows machine
  • Anonymous users should not have access at all
  • One or more users get full access to the FTP root directory, these users will be managed using local Linux accounts

This may seem like a very straight-forward installation, but it's not. vsftpd has a number of example configurations, located in the usr/share/doc/packages/vsftpd/example directory, but my setup is not listed in there.

Installation

vsftpd runs on any Linux kernel, yet the installation instructions may differ per distribution. For Suse, I simply opened Yast, choose the "Add software option", and selected the vsftpd package to install. Next, I had to insert CD 4 and go ahead with the installation. Look up the instructions for your distribution. The rest of this article should work similar irrespective of your distribution.

Security

I wanted to create a separate user for ftp administration access, so I did. This user will have full access to it's own home directory, which will be the shared FTP root directory. Log in as root user, and execute the following commands in the console:

# create the FTP root dir
mkdir /srv/ftp
# create a FTP user group
groupadd ftp-users
# make the new FTP root dir accessible for ftp-users
chmod 750 /srv/ftp
chown root:ftp-users /srv/ftp
# add new ftpadmin user to group and set its home dir to the FTP root
useradd -g ftp-users -d /srv/ftp ftpadmin
# set password of new ftpadmin user
passwd ftpadmin
# give read/write access to the FTP root dir
chmod 770 /srv/ftp

Configuration

This is the most important step. It consists of creating a few configuration files. The most important file is vsftpd.conf, which you should create in the /etc directory. Below is my listing of this file, included with comments:

#disallow anonymous ftp access
anonymous_enable=NO

# allow local users to log in
local_enable=YES

# allow FTP write commands
write_enable=YES

# umask for local users, (022 is used by most other ftpd's)
local_umask=022

# make sure PORT transfer connections originate from port 20 (ftp-data).
connect_from_port_20=YES

# disable chmod, default is YES
chmod_enable=NO

# login banner string
ftpd_banner=Welcome to the s3maphor3 FTP service

# enable/specifiy 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
chroot_list_file=/etc/vsftpd.chroot_list

# authentication service
pam_service_name=vsftpd

# disable user list
userlist_enable=NO

# enable for standalone mode
listen=YES

We have specified to "chroot" users. This means that authenticated FTP users will be directed to the home dir specified in the user account. Since we have this set this up for the ftpadmin account, this is what we want. The list of users to chroot is maintained in a file called vsftp.chroot_list in the /etc directory. Mine looks like this:

ftpadmin

Finally, a third file is needed to complete the configuration. We want the FTP server to start when the system is started, and to be stopped when the system is shutdown. To realize this, we need to create a script file named vsftpd in the /etc/init.d diectory:

#!/bin/sh
case "$1" in
start)
echo "Starting vsftpd ..."
/usr/sbin/vsftpd &
;;
stop)
echo "Stopping vsftpd ..."
killall vsftpd
;;
*)
echo "Usage: 'basename $0' {start|stop}" >&2
exit 64
;;
esac
exit 0

This completes the configuration of vsftpd. Let's test it.

Local test

Before trying to access the FTP server from a remote machine, it is wise to do a local test, to see if your configuration is working without the worries of a firewall. First make sure the vsftpd service is started. It should run automatically when you have rebooted, but you can also kick it manually. Since I run vsftp in stand-alone mode (outside of the xinet network service), the command to start it would be:

/usr/sbin/vsftpd &

The command to stop it is:

killall vsftpd

Now that the service is started, let's do a local test. Here's my successfull FTP session, based on the configuration above:

linux:~ # ftp localhost
Trying 127.0.0.1...
Connected to localhost.
220 Welcome to the s3maphor3 FTP service
Name (localhost:root): ftpadmin
331 Please specify the password.
Password:
230 Login successful.
Remote system type is UNIX.
Using binary mode to transfer files.

If anything goes wrong while starting the service or doing the local test, remember the error number and do a google :)

Firewall settings

Many Linux distributions by default have their firewall enabled. This is a good thing. I found out that Suse does not allow FTP traffic from a remote machine. The way to configure it to allow FTP traffic may differ per distribution. I have used the Yast control panel, security section, firewall, advanced dialog and added port 21 (FTP control) and port 20 (FTP data) to the TCP ports.

Remote test

The last step in the process is testing remote FTP access. For this purpose I have simply used a command prompt as FTP client on my Windows machine. Here's my successfull remote FTP session output:

C:\>ftp 192.168.0.115
Connected to 192.168.0.115.
220 Welcome to the s3maphor3 FTP service
User (192.168.0.115:(none)): ftpadmin
331 Please specify the password.
Password:
230 Login successful.

Where 192.168.0.115 is the IP address of your FTP server. You can check the address in Linux using the ifconfig command (look for inet addr in the output)

This concludes the instructions on how to setup vsftpd for secure users. I hope I'm helping anyone with this, if not, it sure is a good reminder for myself :)

comment » When you open the Firewall in SuSE, in the advanced settings, enter [20 21] into the "Ports" field (no commas). In the "Protocol" Field, add [FTP TCP IP]

Then, stop and restart the Firewall. Control that the settings have been changed (just look again into the "advance" settings, if they are shown.

I'm a newbie too, but after I entered the Protocols I could connect from the remote machines without problem. And, damned, it's fast! «

comment » The autor showing the vsftpd.conf file wrote:

chroot_list_file=/etc/vsftpd.chroot_list (note the letter "d" after vsftp)

After wrote "The list of users to chroot is maintained in a file called vsftp.chroot_list in the /etc directory..." (note there is no letter "d")

As you can see the the file name isn't the same chek in your vsftpd.conf at the parameter [chroot_list_file=] then correct your vsftpd.chroot_list file name!

The connection problem is probably caused by your firewall settings... read the article! «

comment » Thanks for this setup of vsftpd.

Thanks to Shawn B. for adding the file name in vsftpd.conf

I tested ftp lcoalhost and it worked. I went to a XP pc to try to ftp but kept getting time out. I thought about the firewall, port 21 and 20.

Followed the steps to use YAST but could not find how to add port 21 and 20. I did see 4 section tcp, udp, rpc, & ip.

Do I put 21 in the tcp and 20 in ip? Should I put 20, 21 in tcp or put 20 and 21 in tcp?

One last thing which I had problems is the SSL.

vsftpd.conf

ssl_enable=YES did not work with ftp localhost

ssl_enable=NO did work with ftp localhost

I believe I would need ssl enabled but I get an ssl compile error. «

comment » SuSE 10.1 - I wanted a vsftpd server from behind a firewall. No anonymous users.

Install the vsftpd package.

Modify the Firewall.

Yast -> Secruity & Users -> Firewall

Click on "Allow Services" then select "Advanced", add the following ports:

TCP Ports: ftp

UDP Ports: ftp

ftp (in lowercase) is defined within SuSE to mean ports 20 and 21

Yast -> System -> /etc/sysconfig Editor

Network -> Firewall -> SuSEfirewall2

FW_LOAD_MODULES="ip_conntrack_ftp ip_nat_ftp"

This is required for FTP NATing through a firewall. They are kernel modules and seem to require a reboot.

Edit the config file /etc/vsftpd.conf

write_enable=YES

dirmessage_enable=YES

ftpd_banner="Welcome to Womble FTP service."

local_enable=YES

local_umask=022

anonymous_enable=NO

comment » Hello,

username / password via ftp connection is easy to intercept.

To disable login via ssh with username ftpadmin (and login with root), modify the sshd_config:

vi /etc/ssh/sshd_config

# Append following names (directives):

DenyUsers root ftpadmin

DenyGroups root ftpadmin

Best regards,

Arcturus

P.S.: Sorry if doublepost. «

comment » I have two Linux boxes (CentOS 5) on the same network.

With one of them, vsftpd works perfectly. With the second, using a config file cloned from the first, I get "Login Successful" followed immediately by "Connection closed by remote host".

There are no error messages--just the immediate disconnect.

comment » I cant upload or create any directory on my centos 5.Here is my vsftpd.conf

# 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

#

# The target log file can be vsftpd_log_file or xferlog_file.

# This depends on setting xferlog_std_format parameter

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=whoever

#

# The name of log file when xferlog_enable=YES and xferlog_std_format=YES

# WARNING - changing this filename affects /etc/logrotate.d/vsftpd.log

xferlog_file=/var/log/xferlog

#

# Switches between logging into vsftpd_log_file and xferlog_file files.

# NO writes to vsftpd_log_file, YES to xferlog_file

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=apache

#

# 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 bk's 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

#

# When "listen" directive is enabled, vsftpd runs in standalone mode and

# listens on IPv4 sockets. This directive cannot be used in conjunction

# with the listen_ipv6 directive.

listen=YES

#

# This directive enables listening on IPv6 sockets. To listen on IPv4 and IPv6

# sockets, you must run two copies of vsftpd whith two configuration files.

# Make sure, that one of the listen options is commented !!

#listen_ipv6=YES

pam_service_name=vsftpd

userlist_enable=YES

tcp_wrappers=YES «

comment » Hi,

Those who are having issue just remember to backup original file /etc/vsftps.conf

on some systems you might have to comment out the listen directive to get it working. «
