File Servers¶

The access to ProFTPD with Windows is achieved as follows:

• Go to My Computer (Windows Explorer).
• In the address bar at the top type ftp://dietpi:dietpi@192.168.0.100 press enter.

Change 192.168.0.100 to the IP address of your DietPi system.

The access to ProFTPD with an FTP client is achieved as follows:

• Username = dietpi
• Password = The same as your root login password. Default is dietpi
• Address = Your IP address (e.g.: 192.168.0.100)
• Port = 21

The destination directory can be changed by replacing /Path/To/Directory to your target directory (within the configuration file /etc/proftpd/proftpd.conf):

systemctl stop proftpd
sed -i '/DefaultRoot /c\DefaultRoot /Path/To/Directory' /etc/proftpd/proftpd.conf
systemctl start proftpd

Jailing means to lock users to their home folders.

Jailing can be enabled in the configuration file /etc/proftpd/proftpd.conf via

systemctl stop proftpd
sed -i '/DefaultRoot /c\DefaultRoot ~' /etc/proftpd/proftpd.conf
systemctl start proftpd

The access to the Samba file server is achieved as follows:

• Address = \\192.168.0.100\dietpi
• Username = dietpi
• Password = <your global application password> (default: dietpi)

The Samba password can be changed with

smbpasswd -a dietpi

To add/change the valid user do the following steps:

• Edit /etc/samba/smb.conf
  • Search the entry [dietpi], change valid users = username_i_require
  • Add the user to Samba with smbpasswd -a username_i_require
• Restart services with systemctl restart nmbd smbd

You can now connect to the samba server with the username and password you entered above.

The destination directory can be changed by replacing /Path/To/Directory to your target directory (within the configuration file /etc/samba/smb.conf):

sed -i '/path = /c\path = /Path/To/Directory' /etc/samba/smb.conf
systemctl restart nmbd smbd

In case of problems with the Samba share not showing up in the Windows network view, the wsdd daemon (Web Service Dynamic Discovery host daemon) can be installed. This is achieved with the following steps:

apt install wsdd2

systemctl start wsdd2

systemctl status wsdd2

curl -sSfL 'https://pkg.ltec.ch/public/conf/ltec-ag.gpg.key' | gpg --dearmor -o /etc/apt/trusted.gpg.d/dietpi-wsdd.gpg --yes
echo "deb https://pkg.ltec.ch/public/ $G_DISTRO_NAME main" > /etc/apt/sources.list.d/dietpi-wsdd.list
apt update
apt install wsdd

systemctl start wsdd

systemctl status wsdd

The access to vsftpd with Windows is achieved as follows:

• Go to My Computer (Windows Explorer).
• In the address bar at the top type ftp://dietpi:dietpi@192.168.0.100 press enter.

Change 192.168.0.100 to the IP address of your DietPi system.

The access to vsftpd with an FTP client is achieved as follows:

• Username = dietpi
• Password = The same as your root login password. Default is dietpi
• Address = Your IP address (e.g.: 192.168.0.100)
• Port = 21

The destination directory can be changed by replacing /Path/To/Directory to your target directory (within the configuration file /etc/vsftpd.conf):

sed -i '/local_root=/c\local_root=/Path/To/Directory' /etc/vsftpd.conf
systemctl restart vsftpd

The access to the NFS share with an NFS client is achieved as follows:

• Address = IP address of your DietPi system (e.g.: 192.168.0.100)
• Port = 2049

The NFS access configuration is done via export files.
Therefore, the file /etc/exports can be edited as well as adding further export files within the /etc/exports.d directory.

Explanations of the export file format are available in the internet or can be read in the man pages (use man exports, therefore the package man needs to be installed).

After changing the access configuration, the export information can be re-read via command

exportfs -ra

Alternatively the service can be restarted (systemctl restart nfs-server).

The actual access configuration can be displayed with the command

exportfs

On the client side the mountable exports can be queried with the command

showmount -e <NFS_SERVER>

By default the DietPi NFS installation exports the directory /mnt/dietpi_userdata for everyone. This is configured in /etc/exports.d/dietpi.exports. You can edit this file to restrict the access.

E.g. access to the NFS share can be limited to the IP address range of 192.168.0.1-255, by editing /etc/exports.d/dietpi.exports as follows:

/mnt/dietpi_userdata 192.168.0.*(rw,async,no_root_squash,crossmnt,no_subtree_check)

Apply the new configuration via systemctl restart nfs-server or exportfs -ra.

One option to disable NFS v3 is to add a file to the directory /etc/nfs.conf.d/ with the following content:

cat << _EOF_ > "/etc/nfs.conf.d/00-dietpi.conf"
# Disable NFS v3 (to only have NFS v4 enabled)
#
[nfsd]
vers3=n
#vers4=y
#vers4.1=y
#vers4.2=y
_EOF_

A restart of the NFS service is then necessary:

systemctl restart nfs-server

The disabled NFS v3 can be examined with:

root@NFS-server:/etc/nfs.conf.d# cat /proc/fs/nfsd/versions
-3 +4 +4.1 +4.2

The example output gives that NFS v3 is not active (-3) whereas NFS v4 is active (+4 +4.1 +4.2).

To re-enable NFS v3 again, the entry vers3=y can be used, or the complete file /etc/nfs.conf.d/00-dietpi.conf can be deleted (also restarting the nfs-server service afterwards).
