Computer Drive User Manual

These files may be installed in any location on the SSM client machines. The user must have at least
read access to the files.
The SSM startup scripts hpssgui.pl, hpssgui.vbs, hpssadm.pl, and hpssadm.vbs provide the user with a
command line mechanism for starting the SSM client. The hpssgui.pl script is a Perl script for starting
the SSM Graphical User Interface and the hpssadm.pl script is a Perl script for starting the SSM
Command Line User Interface. These scripts work on AIX, Linux, or Windows platforms so long as Perl
is installed on the host. The hpssgui.vbs script is a Visual Basic script for starting the Graphical User
Interface and the hpssadm.vbs script is a Visual Basic Script for starting the SSM Command Line User
Interface. These scripts work only on Windows platforms.
These scripts depend on the ability to read the other files in the package. See the hpssgui and hpssadm
man pages for details.
The hpss.jar file contains the hpssadm and hpssgui program files. This is stored on the server machine
under $HPSS_PATH_BIN; the default location is /opt/hpss/bin. If the SSM source code on the server
machine is recompiled, the hpss.jar file must be redistributed to all of the SSM client machines.
The keytab is used only by the hpssadm program. See Section 3.3.2.3: User Keytabs (For Use with
hpssadm Only) on page 37, for details.
See Section 3.3.4: SSM Help Files (Optiona on page 42, for a description of the Help Files.
A writable directory is required for hpssgui or hpssadm session logs, if these are desired. The session
log is an ASCII file that stores messages generated by the hpssadm or hpssgui programs. By default, the
hpssgui/hpssadm scripts do not create session logs, but it is strongly encouraged that this capability be
enabled by using the -S <location> option when running the script. The recommended location is /tmp
on UNIX-like systems or c:\tmp on Windows systems. See the hpssgui and hpssadm man pages for
more information on creating a session log. Having the session log available helps when debugging
problems with the SSM client applications. It is the first thing that the SSM developers will ask for when
someone is having problems with the hpssgui and/or hpssadm.
3.3.6. Using SSM Through a Firewall
3.3.6.1. The Firewall Problem
hpssgui and hpssadm require the use of several network ports which may be blocked if the client and
System Manager are on opposite sides of a network firewall. Up to three ports may be affected:
• hpssgui and hpssadm must be able to access the port upon which the System Manager listens
for requests.
• If the System Manager follows the default behavior of letting the portmapper select this port,
then hpssgui and hpssadm also need access to port 111 in order to ask the portmapper where
the System Manager is listening.
• If Kerberos authentication is used, then hpssgui and hpssadm additionally need access to
port 88 to communicate with the KDC.
