RESOLVER(SFF)                              UNIX System V



     Name
          resolver - resolver configuration file


     Syntax
          /etc/resolv.conf


     Description
          The resolver configuration file contains information that is
          read  by  the  resolver  routines  the  first  time they are
          invoked by a process.  The file  is  designed  to  be  human
          readable  and  contains  a  list  of  name-value  pairs that
          provide various types of resolver information.

          On a normally configured system  this  file  should  not  be
          necessary. The only name server to be queried will be on the
          local machine and the domain  name  is  retrieved  from  the
          system.

          The different configuration options are:

          nameserver
               followed by the Internet address (in dot notation) of a
               name  server  that the resolver should query.  At least
               one  name  server  should  be  listed.   Up  to   MAXNS
               (currently  3) name servers may be listed; if more than
               one name server  is  specified,  the  resolver  library
               queries each one in the order listed.  If no nameserver
               entries are present, the default is  to  use  the  name
               server  on the local machine.  The algorithm used is to
               try a name server, and if the query times out, try  the
               next, until out of name servers; then repeat trying all
               the name servers until a maximum number of retries  are
               made.

          domain
               followed by an domain name, that is the default  domain
               to  append to names that do not have a dot in them.  If
               no domain entries are present, the domain  returned  by
               gethostname(SLIB)  is  used (everything after the first
               `.').  Finally, if the host name  does  not  contain  a
               domain part, the root domain is assumed.

          The name value pair must appear on a single  line,  and  the
          keyword  (e.g.  nameserver)  must start the line.  The value
          follows the keyword, separated by white space.

     Example
          domain    Lachman.COM
          nameserver     192.35.52.1
          nameserver     192.35.52.2
