3.4 OUT-OF-BAND NETWORK MANAGEMENT

Is all system management traffic to be localized to a specific network? How can the management traffic be localized to a specific network? Here is where the

sortlist of the /etc/resolv.conf file comes in handy (see Appendix B, "Hostname Resolution"). Configure the management station's /etc/resolv.conf file to include the sortlist feature and set the network to the out-of-band network:

domain hpc.hp.com

sortlist 192.168.2.0

nameserver 0.0.0.0

All multi-homed hosts will have the 192.168.2.0 network returned over any other IP on the system. In order for the client to talk to the server through the out-of-band network, each client will need an entry in its /etc/hosts file resolving the hostname of the management server to the IP address the management server's out-of-band interface.

If the resolver does not support the sortlist feature, the nameserver itself may support the feature. If the management server is a nameserver, add the sortlist to the named.conf file and test for proper resolution.

The last possible hope is creating one large /etc/hosts file on the management server. This entails configuring the /etc/hosts file with the IP address of each systems management atop any other IP address for that system.
