RE: [MLUG] DNS question

[Rick Buford <EMAIL:PROTECTED>]

resolver options (from man resolv.conf):
 ndots:n   sets a threshold for the number of dots which must
                        appear in a name given to res_query() (see
                        resolver(3)) before an initial absolute query will
be
                        made.  The default for n is ``1'', meaning that if
                        there are any dots in a name, the name will be tried
                        first as an absolute name before any search list
ele­
                        ments are appended to it.

see also "man nsswitch.conf"
