12.1.3.1 Configuring Your Systems for Line Tracing
The Sun Graphical Management Interface (SunGMI) starts the Sunscope utility
on the selected server’s system by invoking the Unix remote shell (
rsh
)
command. Each operator who wants to run the Sunscope utility must be
allowed to remotely access the server systems from the systems on which they
run the SunGMI. To provide this remote access, add the following entry for
each operator in the
/etc/hosts.equiv
file on each server system:
hostname username
where
hostname is the name of the system on which the operator runs the SunGMI.
username is the operator’s log-in name.
Information in the
/etc/hosts.equiv
file applies to the entire system. In
addition, operators can maintain their own
.rhosts
files in their home
directories.
Note – The
/etc/hosts.equiv
and
.rhosts
files provide the remote
authentication database for the remote access commands
rsh
,
rlogin
,
rcp
, and
rcmd
. The files specify remote hosts and users that are trusted. Trusted users
are allowed to access the local system without supplying a password. Since the
/etc/hosts.equiv
and
.rhosts
files bypass the standard password-based
user authentication mechanism, use care when creating and maintaining these
files.
