Solaris Common Messages and Troubleshooting Guide

No route to host


An operational error occurred because there was no route to the destination host, or because of status information returned by intermediate gateways or switching nodes.

The returned status is not always sufficient to distinguish between a host that is down and a network that is down. Refer to "Network is unreachable".


Check that the network routers and switches are not disallowing these packet transfers. If they are allowing all packet transfers, check network cabling and connections.
