Security Considerations

•Any user can join your network

•Any machine can download any images they want

•Use nimsh[/SSL] versus rsh

•Firewalls–NFS shouldn't be used over a firewall


NIM Configuration Utilities

•smitty nim

•smitty eznim

•wsm

•scripts–nim_setup_master–nim_setup_client–nim_update_all

•Command line


Introducing smitty NIM

Network Installation Management

Configure the NIM Environment

Perform NIM Software Installation and Maintenance Tasks

Perform NIM Administration Tasks

Create IPL ROM Emulation Media


Introducing WSM

Network Installation Manager

Resources Networks MachinesOverview and Tasks(Configure Master)


Introducing the Command Line

•Major Commands:–nimconfig - Configure NIM master–nim - Most operations from master–nimclient - Most operations from the client

•Major nim Operations: –define, bos_inst, cust

Example:

nim -o bos_inst -a spot=spot530 \

-a lpp_source=lpp_source530 \

lpar1


Release Considerations

5.1 - RPMS code can now be installed

5.2 - Can back up multiple mksysbs at a time

lpp_source Management Tools

Resource Groups

Easy Configuration Utilities (smitty eznim/scripts)

5.3 - nimsh

Alternate NIM master

Keep NIM Master at the latest level you plan to support
