How Users Gain Access to the OSS
Environment
A user gains access to the OSS environment through a server process. The most
commonly used server subsystems are Telserv and the file transfer protocol (FTP)
server. Other servers, such as the iTP WebServer httpd process, are beyond the
scope of this guide.
Both Telserv and the FTP server authenticate the user’s login information against the
user definitions configured through either a third-party product or the Safeguard
subsystem. (Section 8, Managing Security, describes configuration of user definitions.)
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
start any executable program correctly configured through the security subsystem,
and through the Telserv SCF product module.
OSS users can optionally redirect one or more OSS standard files using either the
OSH command and a private copy of the OSSTTY utility, or through an OSSTTY
server. OSSTTY appears as a set of terminal devices to an OSS process and behaves
as if it were a Telserv terminal session with three windows. OSS standard files that are
not redirected remain associated with the terminal device provided by Telserv. See
Redirecting OSS Standard Files on page 6-27 and OSSTTY on page C-1 for more
information.
The FTP server provides access initially to either the Guardian environment or to the
OSS environment. The choice of an initial environment depends on:
•
Whether the user is anonymous and which anonymous login is used.
