Other physical machines in the same rack can connect to the second VM as well as the first by any method allowed by the second VM.</div><div><br></div><div>HOWEVER, from my office, I can't connect to the second VM but I can connect to the first VM. Both are on the same physical host. I can connect to all the other physical and VM in the racks from each other and from my office. There are 3 VM exceptions and all three are either new with new static IPs or recycling an old static IP (with a guarantee the orginal host with the old IP is dead and gone - deleted the VM of a second physical host.</div><div><br></div><div>All connections that succeed do so by both IP and name. All connections that fail do so by both IP and name. All names resolve correctly. All unreachable VMs can connect to systems outside the LAN by name and by IP. The public facing IP they have is valid. The netmask is correct as is the gateway.</div><div><br></div><div>The traceroute from my office to a working VM completes in 4 hops with the 4th being the VM itself. But to the non-working VMs it fails after 3. </div><div><br></div><div>The failure point then must be the last router in the traceroute, i.e. the one that shows up last followed by 27 rows of *'s.</div><div><br></div><div>I get exactly the same behavior tracing from a machine elsewhere in the LAN.</div><div><br></div><div>The new VM that can't be connected to is the new user authentication machine. Kind of important.</div><div class="-x-evo-signature-wrapper"><span><pre>--

Every time you stop a school, you will have to build a jail. What you
gain at one end you lose at the other. It's like feeding a dog on his
own tail. It won't fatten the dog.
