Routing Question:

The in.rdisc daemon is only available on Solaris machine it depends on multicasting, which is not present on older SunOS machines. If you do not have an /etc/defaultrouter file on a Solaris machine, any routing host will automatically bring up in.rdisc at boot time. As long as there is at least one router on the same network which advertises Router Discovery messages, in.rdisc will continue running. If nothing responds to the initial Router Discovery queries, in.rdisc on a routing host will automatically quit, and the rc files will fall through to in.routed. Solaris routers will also automatically bring up in.rdisc at boot time, if there is no /etc/defaultrouter file. They will not ever exit, but rather will advertise via Router Discovery messages. If you want in.rdisc to run, you should never have to do anything, other than delete the /etc/defaultrouter file, if it exists, and make sure that at least one Router Discovery compliant router exists on the same subnet as your machine. If you want to disable in.rdisc, you should simply rename it: %%%% mv /usr/sbin/in.rdisc /usr/sbin/rdisc.save In general, in.rdisc should only be run on routing hosts if your local network is relatively complex.
