Solaris Common Messages and Troubleshooting Guide

route: socket: Protocol not supported


During a boot, this error is displayed and the multicast is not configured.


An inittab(4) from a previous release of the operating environment was used. Thus, the following entry, which is required for the route command in the Solaris 2.6 release, was missing from /etc/inittab.

ap::sysinit:/sbin/soconfig -f /etc/sock2path
By default, this is the second entry in the file. After this entry was added, the multicast configured at boot time without error.
