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

Hmmm... then the behaviour you describe seems to both contradict my own experience (double-checked a second ago) as well as the 'resolv.conf(5)' man page: If the lookup keyword is not used in the system's resolv.conf file then the assumed order is bind file. Furthermore, if the system's resolv.conf file does not exist, then the only database used is file. Fun fact , i actually know that but i fail to spot it . Thank you :-) No worries :^) Raf
