Can anyone point out reasons why it might be a bad idea to put this sort of line in your /etc/hosts file, eg, pointing the FQDN at the loopback address?
127.0.0.1 hostname.domain.com hostname localhost localhost.localdomain
Would the application work with a hosts entry like this?
127.0.0.1 hostname.dummy localhost localhost.localdomain
And giving it 127.0.0.1 would tell it others to ignore it, I think.
Where did your user come up with this idea - clearly, they have *no*
clue what
they're doing, and need at least a brown bag lunch about TCP/IP, and they should not be allowed to dictate this. Their "idea" is a bug, and
needs
to be fixed.

You guys do know that the names in your host file only apply to YOU on that machine right? It does not matter if you connect to 127.0.0.1 or something else UNLESS you specifically listen on a specific IP address on that machine AND you need to connect to that address from the machine itself.
<snip> Let me expand on the above: if anyone on *any* other machine is trying to connect to that, it won't work. If they try to point a browser to it, unless they've done ssh -X to the server, they'll talk to their *own* machine, and it won't be found.
