35.2. FTP tables

35.2. FTP tables
	Chapter 35. FTP - File Transfer Protocol

The access to FTP resources is based on:

Authentication of the user in the Users table;
Creation of a virtual path in the FTP Virtual Roots Path table;
Creation of an access rights for that virtual Path in the FTP Virtual Paths Access Rights table.

35.2.1. Users table

Users can access to FTP server only if they're enabled to FTP service (parameter FTP set to YES).

-------------------------------------------------------------------------------

Meaning of the parameters:

FTP: Enables/disables the FTP service.
FTP-HOMEDIR: FTP user's home directory.
FTP-PROT: User's access protocol [PLAIN: not encrypted; SSL: encrypted].

35.2.2. FTP Virtual Root Paths table

FTP Virtual Paths Table specifies the association between virtual paths and their respective physical paths.

Virtual paths can be added/set/displayed/cleared with the commands:

a/s/d/c ftp path:<virtual path> [phys-path:<physical path>]

The whole table can be shown with the following command. By default the table contains the following entries:

[17:16:13] ABILIS_CPX:d ftp path

Parameter:  | Value:
------------+------------------------------------------------------------------
PATH:         /pub/
PHYS-PATH:    C:\USR\PUB\
-------------------------------------------------------------------------------
PATH:         /pub2/
PHYS-PATH:    D:\USR\PUB\
-------------------------------------------------------------------------------
PATH:         /usr/
PHYS-PATH:    C:\USR\
-------------------------------------------------------------------------------
PATH:         /usr2/
PHYS-PATH:    D:\USR\
-------------------------------------------------------------------------------

To show a specific path:

[17:25:52] ABILIS_CPX:d ftp path:/pub/

Parameter:  | Value:
------------+------------------------------------------------------------------
PATH:         /pub/
PHYS-PATH:    C:\USR\PUB\
-------------------------------------------------------------------------------

Meaning of the parameters:

PATH: Specifies a virtual directory path with UNIX notation. Virtual path / needs not to be specified because / does never refer to physical path, it is only the “container” of virtual paths. The maximum length is 32 characters.
PHYS-PATH: Specifies a physical directory path, with DOS notation (it starts with the disk letter and it ends with the character \ ). The maximum length is 128 characters.

35.2.3. FTP Virtual Paths Access Rights table

This table specifies the associations between virtual paths, users and their respective access rights.

Access rights for a specific virtual path can be added/set/displayed/cleared with the following commands.

a ftp rights path:<virtual path> |id:<id>: Adds the path only.
a ftp rights path:<virtual path> |id:<id> [user:<user> file:<file rights> dir:<dir rights> recur:yes|no mode:plain,ssl]: Adds user and path.
s ftp rights path:<virtual path> |id:<id> user:<user> [file:<file rights> dir:<dir rights> recur:yes|no mode:plain,ssl]: Sets rights and other parameters for an already existent user.
c ftp rights path:<virtual path> |id:<id> user:<user>: Deletes an existing user; if the user is the last one the path isn't deleted.
d ftp rights: Displays rights summary.
d ftp rights path:<virtual path> | id:<id>: Displays rights for a specific path.
d ftp rights user:<user>: Displays rights that a user has on all paths; the paths for which the user isn't defined are skipped.

An example of the output (by default the table contains the following entries):

[17:53:58] ABILIS_CPX:d ftp rights

-------------------------------------------------------------------------------
ID: PATH:
       USER:                            FILE: DIR:  RECUR: PROT:

       admin                            rwdn  lcdn  YES    PLAIN,SSL
       anonymous                        r---  l---  YES    PLAIN,SSL
-------------------------------------------------------------------------------
  2 /pub2/
       admin                            rwdn  lcdn  YES    PLAIN,SSL
       anonymous                        r---  l---  YES    PLAIN,SSL
-------------------------------------------------------------------------------
  3 /sysdrives/
       admin                            rwdn  lcdn  YES    PLAIN,SSL
-------------------------------------------------------------------------------
  4 /usr/
       admin                            rwdn  lcdn  YES    PLAIN,SSL
-------------------------------------------------------------------------------
  5 /usr2/
       admin                            rwdn  lcdn  YES    PLAIN,SSL
-------------------------------------------------------------------------------

The rights are split in “file rights” and “directory rights” and are configured/viewed with two different parameters: FILE and DIR.

Table 35.1. FILE parameters values

R	W	D	N
Read	Write	Delete	Rename

Table 35.2. DIR parameters values

L	C	D	N
List	Create	Delete	Rename

The syntax is:

FILE:[+|-R][+|-W][+|-D][+|-N] DIR:[+|-L][+|-C][+|-D][+|-N]

The + sets granted right.
The - sets denied right.
If + or - isn't specified, the value + is assumed, so it may be omitted.
Not specified right is left unchanged.
FILE and DIR values do not care about the characters' position.
FILE and DIR values are case insensitive.

The following commands are equivalent:

S FTP RIGHTS PATH:/ USER:test FILE:+R+W+D+N
S FTP RIGHTS PATH:/ USER:test FILE:rwdn
S FTP RIGHTS PATH:/ USER:test FILE:NdwR
S FTP RIGHTS PATH:/ USER:test FILE:+D-N
S FTP RIGHTS PATH:/ USER:test FILE:D-N
S FTP RIGHTS PATH:/ USER:test FILE:-ND
