Distributed SMIT 2.2 for AIX: Guide and Reference

Installing DSMIT

The Distributed System Management Interface Tool (DSMIT) program provides the following software installation package for DSMIT servers and clients:

DSMIT Server Must be installed on AIX systems designated as DSMIT servers. During installation the following DSMIT configuration files are created:
  • /usr/share/DSMIT/dsmitos
  • /usr/share/DSMIT/hosts
    Note: Do not install the AIX Distributed SMIT server package on an AIX system that has been defined as a diskless workstation client.
DSMIT Client You must install the DSMIT 2.2 client code. The client code from previous versions of DSMIT does not contain the security enhancements that allow it to interoperate with DSMIT Version 2.2.

DSMIT provides the following software installation packages to establish DSMIT clients:

DSMIT AIX 4.1 Client Must be installed on AIX 4.1 systems designated as DSMIT clients.
Note: If you are reinstalling the DSMIT AIX client software package over an existing DSMIT AIX client, do not use DSMIT to do this. You must use the standard installation procedures.
DSMIT AIX 3.2.5 Client Must be installed on AIX systems designated as DSMIT servers for systems running the AIX Version 3.2.5 operating system.

The installation process creates install images in the /usr/share/DSMIT/AIX_3.2/inst.images directory that must be copied to each of the AIX Version 3.2.5 clients and installed using SMIT or the installp command.

Next, the DSMIT database for managing AIX Version 3.2.5 machines must be established on the DSMIT servers. For instructions on establishing the DSMIT database, see "Databases" .

DSMIT Sun OS 4.1.3 Client Must be installed on AIX systems designated as DSMIT servers for systems running Sun Microsystems' Sun OS 4.1.3 operating system. The installation provides the necessary configuration for DSMIT to support Sun clients.

The installation process creates a shell script and a tar image in the /usr/share/DSMIT/SunOS_4.1.3/inst.images directory, which must be copied to the Sun clients. The install script provides the procedures to extract the files from the tar image and update the appropriate system files required to run DSMIT. The tar image contains the DSMIT daemons and programs. Managing devices and subsystems on the Sun system may require special system configuration. See "System Configuration for Sun OS and HP" for more information.

DSMIT Solaris Client Must be installed on AIX systems designated as DSMIT servers for systems running Solaris 2.3 or Solaris 2.4 operating system. The installation provides the necessary configuration for DSMIT to support Solaris clients.

The installation process creates a shell script and a tar image in the /usr/share/DSMIT/Solaris/inst.images directory, which must be copied to the Solaris clients. The install script provides the procedures to extract the files from the tar image and update the appropriate system files required to run DSMIT. The tar image contains the DSMIT daemons and programs. Managing devices and subsystems on the Solaris system does not require special system configuration.

DSMIT HP-UX 9.0 Client Must be installed on AIX systems designated as DSMIT servers for systems running Hewlett-Packard's (HP) HP-UX 9.0 700 series operating system. The installation provides the necessary configuration for DSMIT to support HP clients.

The installation process creates a shell script and a tar image in the /usr/share/DSMIT/HP-UX_9.0/inst.images directory, which must be copied to the HP clients. The install script provides the procedures to extract the files from the tar image and update the appropriate system files required to run DSMIT. The tar image contains the DSMIT daemons and programs. Managing devices and subsystems on the HP system may require special system configuration. See "System Configuration for Sun and HP" for more information.

Note: If you wish to use the same AIX system as both a DSMIT server and a DSMIT client, you must install both the server and client software packages.

Software Requirements

Software Installation Specifications

When you install the client software, the /etc/inetd.conf and /etc/services files are updated on client systems. The updates contain information necessary for the correct operation of the DSMIT daemons. The following lines are added to the inetd.conf file during installation:

rexs dgram udp wait root /usr/dsmit/bin/crexd crexd -t30
rexs stream tcp nowait root /usr/dsmit/bin/srexd srexd -i

Two flags are passed to the daemons upon invocation. The -t flag (optional) indicates the number of seconds the system waits after processing the last request before terminating. After 30 seconds the crexd daemon shuts down. It starts again on the next call to crexd.

The -i flag indicates that inetd started srexd. Do not remove it.

The following lines are added to the services file during installation:

rexs 6126/tcp #srexd port
rexs 6125/udp #crexd port

The system changes these files automatically when you issue the installp command.

Once the inetd.conf and services files have been updated, the DSMIT daemons must be started. The installation program will refresh the inetd daemon.

For more information on installing optional software on AIX systems, see the AIX Installation Guide.

DSMIT Server Installation

If you plan to have more than one managing system, you should install the DSMIT server code on one of them and initialize the security configuration before installing the other managing system.

If you plan to manage AIX 3.2, HP-UX 9.0, Sun OS 4.1.3, Solaris 2.3, or Solaris 2.4 systems, you should also install the DSMIT client packages for these systems on the managing system at this time.
