9.4.2.3. Updating From the Command Line
Like the website, command line use of the
Red Hat Update Agent
is affected by the limitations of
UNIX package management. That said, most core functions can still be accomplished through the
up2date
command. The most significant difference is the absence of all options regarding source
files. Refer to
Table 9.3, “Update Agent Command Line Arguments”
for the precise list of options
available for UNIX systems.
The command line version of the
Red Hat Update Agent
accepts the following arguments on UNIX
systems:

9.5. Remote Commands
With UNIX support, RHN offers the flexibility of issuing remote commands on client systems through
the Satellite's RHN website. This feature allows you to run virtually any (compatible) application or
script on any system in your domain without ever having to open a terminal.
9.5.1. Enabling Commands
With the flexibility this tool offers comes great risk and the responsibility to mitigate that risk. For all
practical purposes, this feature grants a root BASH prompt to anyone with administrative access to the
system on the website.
This can be controlled, however, through the same config-enable mechanism
used to determine which systems can have their configuration files managed by
Red Hat Network. Refer to
Section 6.4.2.9.3, “System Details � Configuration —
