Hi!

I don't know whether it matters, but the canonical form of host file entries
is
<IP> <FQHN> [<alias>]...

If you are also using a nameserver, make sure the FQHN in the host file
matches the name in DNS.

Also we run a different version, but we also set "name" of the node. ANd we
have the address explicitly, not the network (host) name...
