User and User-Group Attributes
Telserv provides access in the following ways:
•
Indirectly, when the user selects the TACL service, logs in to the Guardian
environment from a TACL prompt, and then enters the OSH command. (See the
osh(1) reference page either online or in the Open System Services Shell and
Utilities Reference Manual.)
•
Directly, when the user logs in to a direct service that invokes the OSH command
to start an OSS shell.
•
Directly, when the user logs in to a direct service that uses the OSH command to
invoke any executable program correctly configured through the Safeguard
subsystem and the Telserv SCF product module.
The initial working directory for the user is determined by the way the user definition is
configured and by the Telserv service that the user selects.
The FTP server provides access in the following ways:
•
Directly to the Guardian environment, when either of the following is true:
°
No initial working directory is configured for the user of the FTP client.
°
An initial working directory with a name that begins with the characters /G/ is
configured for the user of the FTP client.
The FTP user must use an FTP client quote OSS command to gain access to the
OSS environment. (See the ftp(1) and ftpserver(7) reference pages either
online or in the Open System Services Shell and Utilities Reference Manual. The
use of the quote OSS command is also discussed in the TCP/IP Applications and
Utilities User Guide.)
•
Directly to the OSS environment, when an initial working directory in the OSS file
system is configured for the user of the FTP client. (The FTP user can use an FTP
client quote guardian command to gain access to the Guardian environment.)
•
Anonymously, providing direct access to either the OSS environment or the
Guardian environment. An anonymous FTP user cannot use an FTP client
quote OSS or quote GUARDIAN command to gain access to the other
environment.
User and User-Group Attributes
All NonStop operating system users can use either the Guardian environment or the
OSS environment. However, additional attributes should be configured for OSS
environment users.
In the Guardian environment as well as the OSS environment, users and user groups
can have the following attributes:
•
A user definition can belong to up to 32 user groups.
°
An administrative user group has a group number in the range 0 through 255.
