No route to host

Cause

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. See the "Network is unreachable" message.

Action

Check the network routers and switches to see if they are disallowing these packet transfers. If they are allowing all packet transfers, check network cabling and connections.

Technical Notes

The symbolic name for this error is EHOSTUNREACH, errno=148.
