FTP

Note

The FTP protocol is insecure: password are sent in clear text.

The FTP server allows to transfer files between client and server.

A FTP user can be virtual or a system users. Virtual users can access only the FTP server. This is the recommended configuration. The web interface allows the configuration only of virtual users.

When accessing the FTP server, a user can explore the entire filesystem accordingly to its own privileges. To avoid information disclosure, the FTP user can be configured in a jail using the chroot option: the user will not be able to exit the jail directory.

This behavior can be useful in case a shared folder is used as part of a simple web hosting. Insert the shared folder path inside the custom field. For example, given a shared folder called mywebsite, fill the field with:

/var/lib/nethserver/ibay/mywebsite

The FTP virtual user will be able to access only the specified directory.

System users

Warning

This configuration is highly discouraged

After enabling system users, all virtual users will be disabled. All configuration must be done using the command line.

Enable system users:

config setprop vsftpd UserType system
signal-event nethserver-vsftpd-save

Given a user name goofy, first make sure the user has Remote shell access. Then, enable the FTP access:

db accounts setprop goofy FTPAccess enabled
signal-event user-modify goofy
signal-event nethserver-vsftpd-save

To disable an already enabled user:

db accounts setprop goofy FTPAccess disabled
signal-event nethserver-vsftpd-save

If not explicitly disabled, all system users are chrooted. To disable a chroot for a system user:

db accounts setprop goofy FTPChroot disabled
signal-event nethserver-vsftpd-save
