Managing SNAplus2 from NetView
Using UCF
Using UCF
UCF enables a NetView operator to issue HP-UX commands on a
computer running SNAplus2 by typing the command text at the NetView
console, and to view output from these commands. The facility is not
restricted to commands related to SNAplus2; subject to the restrictions
in “Permitted Commands”, any type of command can be issued.
By using UCF, a remote operator can monitor activity on the SNAplus2
computer, diagnose problems, and in some cases take corrective action.
You can specify whether SNAplus2 supports UCF by using the
define_rcf_access command (refer to HP-UX SNAplus2
Administration Command Reference). If the configuration specifies that
UCF is supported, SNAplus2 starts the UCF daemon program when the
node is started. The UCF daemon processes HP-UX commands from the
UCF by starting a new HP-UX shell for each command and running the
command in that shell. If UCF support is not included, SNAplus2 does
not start this program.
The configuration specifies the name of the UCF user, which must be a
valid login name on the SNAplus2 computer. The UCF shell is started
using the shell program, login ID, permissions, and .login or .profile
specified for that user. (If no shell program is specified, /bin/sh is used.)
This means that the normal HP-UX system security features can be used
to restrict the UCF user's access to files and commands, and therefore to
limit the range of commands available from UCF.
For more information about setting up the UCF configuration, refer to
the description of the define_rcf_access command in HP-UX
SNAplus2 Administration Command Reference.
UCF Command Syntax
The syntax of a UCF command is as follows:
runcmd sp=spname, appl=unix, HP-UX_command
NetView uses the runcmd utility to send a command to a remote system.
The command includes the following parameters:
sp=spname
