This is due to the fact that both 'host' and 'dig' are *DNS* lookup utilities - for obvious reasons, they care only about 'nameserver' entries in '/etc/resolv.conf'. For other utilities, which rely on gethostbyname(3) and gethostbyaddr(3), the 'lookup' option specifies the database and, if more than one, the order which is to be searched for host information. In your example above, 'lookup' is only set up for '/etc/hosts' hence utilities like 'ftp', or 'curl', fail - change it to 'lookup file bind' (or remove that line altogether) and everything will go back to normal. Remove 'nameserver' options from there and, as you might expect, DNS lookups themselves will fail. Raf
