I really think it's a bad idea to be making all these names changes.  You're making things much much harder for yourselves.

Instead of repointing everything to a new host, you should have just changed the DNS to point the name "linux1" to the IP address of the new server.  That way you wouldn't need to reconfigure all of the clients.  That's the whole point of  name service: use a name so that you don't need to point to a number.

Also, pointing to an IP address for this stuff is not a good idea.  If the IP address of the server changes, everything will break again.

Just point everything to linux1, and make the DNS entries for linux1 point to the IP address of chiara.  You're doing all this work for nothing!

RXA: Of course, I understand what DNS means. I wanted to make the changes to the startup to remove any misconfigurations or spaghetti mount situations (of which we found many). The way the VME162 are designed, changing the name doesn't make the fix - it uses the number instead. And, of course, the main issue was not the DNS, but just that we had to setup RSH on the new machine. This is all detailed in the ELOG entries we've made, but it might be difficult to understand remotely if you are not familiar with the 40m CDS system.
