svcorder(4)                 TCP/IP 5.4 Rel. 2.01                 svcorder(4)


NAME
       svcorder - file that specifies name/address resolution order

DESCRIPTION
       Use the file /etc/svcorder to configure the order and the means to
       perform name/address resolution.  If the file /etc/svcorder exists,
       the first line (record) is read.  The line is made up of one or two
       fields. If there are two fields, white space separates them.

       The first field determines the order in which different address
       resolution methods are tried.  It consists of any combination of the
       following values separated by a colons:

       YP or yp       for Network Information Services (NIS)

       RES or res     for the resolver

       EHOSTS or ehosts
                      for the /etc/hosts file

       The optional second field is a comment. Begin it with a # character.

EXAMPLE
       The following line specifies that address resolution should be
       attempted by NIS first.

            yp:ehosts:res

       If NIS is running and cannot resolve the name/address pair,
       name/address resolution goes no farther.  However, you can configure
       NIS so that it uses the domain name system (DNS) when it cannot
       resolve a name/address pair after consulting its own database.  Note
       that DNS must be set up on your system before you can use it.  See
       Managing TCP/IP on the DG/UX System for more information on DNS.  You
       can configure NIS to use DNS in two ways.  You can enter the
       following command line:

            make INTERDOMAIN=-b hosts

       You can also change the "INTERDOMAIN=" line in the /etc/yp/Makefile
       script to read "INTERDOMAIN=-b".  In either case, make sure there is
       no space before or after the equals (=) sign.  The latter method
       enables the domain name system automatically whenever a change is
       made in the hosts map.  For more information, see Chapter 3 in
       Managing ONC/NFS and Its Facilities on the DG/UX System.

       If NIS is not running, /etc/hosts is consulted for name address
       resolution.  If /etc/hosts does not produce an answer, the domain
       name system is consulted.

       If the /etc/svcorder file does not exist, the order in which
       different resolution methods are tried is as above.
