Really ? Something like ping 127.0.0.1 ? Or running some server, then connecting to 127.0.0.1 ? Any hint for testing will be appreciated.Yes to both questions. If the loopback interface is working you should get an answer when you ping localhost. And you can run ftpd and ftp to localhost. Jo Evendoes a lookup to "localhost" work, or a "ping localhost"? does the localhost entry in /etc/resolv.conf affect this?
I don't recall if the localhost entry must be present in /etc/resolv.conf, but you can always ping 127.0.0.1.
