Follow these steps

1. Gather the necessary information:
   • Your Computer Name
     Example: sac

     Your domain name

     Example: comet.ucar.edu

     Your IP Address

     Example: 128.117.110.115

     Your subnet mask

     Example: 255.255.255.0

     Your DNS (Domain Name Service) name & IP address

     Example: ns.noaa.gov and 140.90.231.19

     Your Gateway name & IP address

     Example: comet.ucar.edu and 128.117.110.3

   Consult your internet provider for help with this information.

2. Plug your machine into the network

3. Become root

   % su -

4. Make a backup copy of your netconf and resov.conf files.

    
   % mv /etc/rc.config.d/netconf /etc/rc.config.d/netconf.bak
   % mv /etc/resolv.conf /etc/resolv.conf.bak

   (Note, if you do not have a resolv.conf file, just skip that step. Be sure that you do make a copy of your netconf file, though.)

5. Copy a new version of the netconf file from /usr/newconfig/etc/rc.config.d

   % cp /usr/newconfig/etc/rc.config.d/netconf /etc/rc.config.d/netconf

   This is a very important step. Do not skip it.

6. Run the script /sbin/set_parms with the ip_address flag to configure networking, system hostname, and IP address.

   % /sbin/set_parms ip_address

7. Answer the questions.

8. Now run the script /sbin/set_parms with the addl_netwrk flag to configure routing (gateways), DNS, and/or NIS.

   % /sbin/set_parms addl_netwrk

9. Answer the questions.

10. Reboot

    Now your SAC is configured for the internet, DNS, etc.

    Other things to do:

    • If you have installed DNS, you should change the default behavior for looking up hostnames. As it was in 9.X, the default behavior is to first use DNS to look up a hostname. However, in case your DNS is unavailable, you want your system to first check your /etc/hosts file. To do this, you should copy the /usr/examples/nsswitch/nssw.filesdns file into /etc/nsswitch.conf:

      % cp /usr/examples/nsswitch/nssw.filesdns /etc/nsswitch.conf
