Ftp Server; General - HMS Anybus Communicator User Manual

5. FTP Server

5.1 General

The built-in FTP server provides a way to access the file system using a standard FTP client.
The following port numbers are used for FTP communication:
• TCP port 20 (FTP data port)
• TCP port 21 (FTP command port)
Security Levels
The FTP server features two security levels; admin and normal.
• Normal-level users
The root directory will be "\user".
• Admin-level users
The root directory will be "\", i.e. the user has unrestricted access to the file system.
User Accounts
The user accounts are stored in two files, which are protected from web access:
• "\user\pswd\sys_pswd.cfg"
This file holds the user accounts for normal-level users.
• "\pswd\ad_pswd.cfg"
This file holds the user accounts for admin-level users.
File Format:
The format of these files are as follows:
Username1:Password1
Username2:Password2
Username3:Password3
Note: If no valid user accounts have been defined, the Anybus Communicator will grant admin-level
access to all users. In such case, the FTP accepts any username/password combination, and the root
directory will be "\".
