How to Stop ProFTPD in Superb Mini Server, while testing FTP Transfers with vsftpd (Very Secure FTP Daemon)

I needed to do this to find out why the proftpd transfers were SLOW, and why it kept being terminated as the
LARGE Folder I was transfering was being transfered.  Samba transfers were being terminated also............

1.  Find out where inetd & xinetd are located to find what can/is being used to start the software, as needed.

[code]
locate inetd.conf
locate xinetd.conf
nano /etc/inetd.conf
nano /etc/xinetd.conf
[/code]


2.  Find out where vsftpd.conf is located, and edit the vsftpd configuration.

[/code]
locate vsftpd.conf
nano /etc/vsftpd.conf
[/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=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=whoever
#
# 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.
# Note that the default log file location is /var/log/xferlog in this case.
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 to let you know this is the file being used.....:
ftpd_banner=Welcome to SMS vsftp 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_local_user=NO
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 (rather
# than from inetd) and listens on IPv4 sockets. To use vsftpd in standalone
# mode rather than with inetd, change the line below to 'listen=YES'
# 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 with two configuration files.
# Make sure, that one of the listen options is commented !!
#listen_ipv6=YES
#
check_shell=NO
#


3.  Create the user list.

[code]
nano /etc/vsftpd.chroot_list
[/code]

#insert the user in the file & save:
#
larry


4.  Locate the passwd file and view.

[code]
locate passwd
nano /etc/passwd
[/code]


5.  Create the user directory, that the user will be jailed into!

[code]
sudo mkdir -p /home/ftp/larry
sudo useradd larry -d /home/ftp/larry/ -s /bin/false
sudo passwd larry
sudo chown larry:larry larry 
cd /home/ftp
sudo chown larry:larry larry 
chmod 777 larry
ls -alt
pwd
cd /
[/code]


6.  Check the following files.....user_list & ftpusers:

[code]
nano /etc/vsftpd/user_list
nano /etc/ftpusers
cd /home/ftp/larry
ls -alt
[/code]


7.  Stop Proftpd during testing. 

[code]
/etc/rc.d/rc.proftpd stop
[/code]

Other useful commands are.........:
[code]
/etc/rc.d/rc.proftpd start
/etc/rc.d/rc.proftpd restart
[/code]


8.  Start vsftpd in the background.

[code]
/usr/sbin/vsftpd &
[/code]


9.  Use Filezilla from another local network computer to login, and transfer LARGE files and check transfer rates, making sure the process continues and completes.

USE QUICKCONNECT...........
serverIPaddress
loginusername
userpassword
port_21


10. Terminate the transfer, logout, then reboot Superb Mini Server.  Next we'll modify the proftpd configuration file.


11. Edit proftpd.conf to make proftpd work the same as vsftpd.

[code]
nano /etc/proftpd.conf
[/code]

#FILE CONTENTS & ADDED File Size Parameter:
# MaxLoginAttempts 3  - EXISTS IN FILE
MaxStoreFileSize *
# TimeoutLogin 300  - EXISTS IN FILE

#MODIFY CONTENTS: 
TransferRate RETR 12000
TransferRate STOR 12000
TransferRate STOU 12000
TransferRate APPE 12000


At this point proftpd, and vsftpd should both work very well transfering your files to the Superb
Mini Server with your Filezilla Client Software.
