The configuration of the module allows configuring three types of access, each of them can be
independently enabled or disabled: anonymous read-only access, password-based access for reading,
password-based access for reading and recording. Each access type has its own root directory.
The following configuration is given at the screenshot below:
●
Anonymous access to the contents of the miniSEED file archive is allowed;
●
Reading only access to the log directory for the
log
login is allowed;
●
Full access to the memory card contents for the
sdcard
login is allowed.
Changing the FTP server configuration requires super-user rights so the password to the
debian user account will be requested.
Logins for the reading only access and the full access must be different.
It is recommended opening the anonymous access only for directories on the device’s SD card.
Never access the NDAS-RT system directories anonymously. It may grant attackers access to
reading files containing critical information such as passwords.
10. Disk Cleaner program module
The
Disk Cleaner
module is an integrated module of the NDAS-RT system and is used to clean
the device memory from the oldest files. The module periodically checks the free space of the disk. If
the volume of free space is less than the specified threshold, the module sequentially removes the oldest
files until the required space volume becomes available. When finished, the module removes empty
directories that may remain after removing the files.
The module does not analyze the contents of files, timestamps in the signal, etc. The module
sorts the files by the time of the last change according to their attributes in the file system.
