als erstes benötigen wir die Basis, einen FTP, den SSL und den SSH Service:


BASH code

  1. sudo apt-get install proftpd-basic openssl openssh-server



sudo mkdir /etc/proftpd/ssl
cd /etc/proftpd/ssl
sudo openssl genrsa -out ftpsserver.key 2048
sudo openssl req -new -key ftpsserver.key -out ftpsserver.csr
sudo openssl x509 -req -days 3650 -in ftpsserver.csr -signkey ftpsserver.key -out ftpsserver.crt
sudo addgroup ftpuser
sudo adduser --shell /bin/false --ingroup ftpuser mastercad

sudo nano /etc/proftpd/proftpd.conf

#
# /etc/proftpd/proftpd.conf -- This is a basic ProFTPD configuration file.
# To really apply changes, reload proftpd after modifications, if
# it runs in daemon mode. It is not required in inetd/xinetd mode.
#

# Includes DSO modules
Include /etc/proftpd/modules.conf

# Set off to disable IPv6 support which is annoying on IPv4 only boxes.
UseIPv6 off
# If set on you can experience a longer connection delay in many cases.

# Port 21 is the standard FTP port.
Port 20

# In some cases you have to specify passive ports range to by-pass
# firewall limitations. Ephemeral ports can be used for that, but
# feel free to use a more narrow range.
# PassivePorts 49152 65534

# If your host was NATted, this option is useful in order to
# allow passive tranfers to work. You have to use your public
# address and opening the passive ports used on your firewall as well.
# MasqueradeAddress 1.2.3.4

# This is useful for masquerading address with dynamic IPs:
# refresh any configured MasqueradeAddress directives every 8 hours

# DynMasqRefresh 28800


# To prevent DoS attacks, set the maximum number of child processes
# to 30. If you need to allow more than 30 concurrent connections
# at once, simply increase this value. Note that this ONLY works
# in standalone mode, in inetd mode you should use an inetd server
# that allows you to limit maximum number of processes per service
# (such as xinetd)
MaxInstances 30

# Set the user and group that the server normally runs at.

# Umask 022 is a good standard umask to prevent new files and dirs
# (second parm) from being group and world writable.

# Normally, we want files to be overwriteable.

# Uncomment this if you are using NIS or LDAP via NSS to retrieve passwords:
# PersistentPasswd off

# This is required to use both PAM-based authentication and local passwords
# AuthOrder mod_auth_pam.c* mod_auth_unix.c

# Be warned: use of this directive impacts CPU average load!
# Uncomment this if you like to see progress and transfer rate with ftpwho
# in downloads. That is not needed for uploads rates.

# In order to keep log file dates
consistent after chroot, use timezone info
# from /etc/localtime. If this is not set, and proftpd is configured to
# chroot (e.g. DefaultRoot or ), it will use the non-daylight
# savings timezone regardless of whether DST is in effect.
