Every hostname → IP resolving and every IP → hostname resolving goes in the following order: 1) /etc/hosts 2) libnss-myhostname I honestly don't know what scares me most about libnss-hostname - the need of it in the first place, the author of the library, software that behaves funny without it or the setups that genuinely need it :( 3) avahi-daemon Uses funny IPs from 169.254.0.0/16 range and (in)famous .local domain. Not needed if you have DNS in your LAN. NOTFOUND=return belong to mdns4_minimal in this setup, and, according to nsswitch.conf(5), means 'The lookup succeeded, but the requested entry was not found'. In this particular case it means 'regardless of result of queries to resolve anything in .local domain - stop here, don't go further'. 4) Plain good old Domain Name Server, or several, according to the /etc/resolv.conf (or its equivalent if resolvconf is used). > Further, I'm wondering if; where it says myhostname... it is supposed > to be edited with my actual host name? No, please read the output of 'apt-cache show libnss-myhostname'. It'll explain this 'myhostname' thing to you better that I can.
