One thing that is different about nslookup on HP-UX (which doesn't have host) is that it actually respects nsswitch.conf so will give you results from /etc/hosts OR from name services whereas most implementations only do it from name services.
Nslookup is "deprecated" meaning you should use host where possible. Also for DNS troubleshooting dig is a much better tool than nslookup or host. -----Original Message----- From: bind-users-bounces+jlightner=water....@lists.isc.org [mailto:bind-users-bounces+jlightner=water....@lists.isc.org] On Behalf Of Martin McCormick Sent: Wednesday, October 12, 2011 1:22 PM To: 'bind-users@lists.isc.org'; mar...@dc.cis.okstate.edu Subject: host versus nslookup Many years ago, various flavors of unix began distributing a utility called host which did almost the same thing as nslookup. Host is what I use most of the time, now, and I actually thought that nslookup on unix systems was maybe going away. A coworker recently asked me about nslookup on our FreeBSD system and I verified the behavior he was asking about. Other than a different output format, what are the advantages of having both host and nslookup. On the FreeBSD system in question, nslookup is definitely a different binary than is host so one is not hard-linked to the other. The behavior he was asking about was simply that all foreign domains that one looks up with nslookup report as non-authoritative since the DNS one is using isnot authoritative for, say, microsoft.com or yahoo.com. This is not a problem. I am just curious. Many thanks.
