Configuring and Managing FTP
15.1 Managing FTP
When you use TCPIP$CONFIG to establish an ANONYMOUS account,
a new account is created with the UIC [TCPIP,ANONYMOUS] (numeric
[3375,xx]), user name ANONYMOUS, account ANONY, default directory
SYS$SYSDEVICE:[ANONYMOUS], and the following types of login access:
network full access
batch no access
local no access
dialup no access
local no access
The usual OpenVMS file protection codes restrict file access for inbound
anonymous FTP sessions to this directory, its subdirectories, and files with
an owner attribute of [TCPIP,ANONYMOUS].
When the ANONYMOUS account has been created, a remote FTP client can:
• Copy files to and from GUEST$PUBLIC.
• From the ANONYMOUS$USER directory:
Delete files
Create directories
Delete directories
Rename files
Rename directories
You can set up guest and public directories for bulletin board or group interest.
Make sure the directory protections are set to read-only or read/write, as needed.
In the following example, UNIX user ubird connects to the ANONYMOUS
account on OpenVMS host TRAGOPAN. TRAGOPAN asks for
ubird ’s password,
which is not echoed. In response to this request, the user should supply the local
system user name for identification purposes.

15.1.2.1 Concealed File Systems
The FTP server processes each command individually as it receives the command
and displays a reply based on the command parameters. A reply can include a
file specification that displays part of the server file system.
For security, anonymous FTP masks file system devices and directories in FTP
replies. The following messages show the difference between an unmasked file
structure, shown in the first reply, and the less-specific, masked structure in the
second reply.
