OK. Ethtool eth3 showed that the link was indeed down.<br>
A wire test showed a wiring problem in the Ethernet cable. I had
already accessed the cluster from it using the router so a wire must
have broken when I moved it to the server. Now fixed and running.<br>
<br>
Anyhow thanks for all help.<br>
