To configure a Sun system to properly exist on the UW campus network, do the
following steps:

o Register an IP address with your departmental network administrator,
or with "netops@cac.washington.edu".

o If you do not yet have an domain name for you department, you will
need to register one with "domainmaster@cac.washington.edu".  This will
require approval by your departmental chair, so talk to them to begin
the process of coming up with a good name for your department on the
network.  You departmental domain name will have ".washington.edu"
added to it, so you should make it relatively short (e.g., 4-7 characters).

o If you already have a domain name (for the sake of examples, the name
"cac" is used here; substitute your own domain name wherever "cac"
occurs), give this name to "domainmaster@cac.washington.edu" along with
the name of your computer, IP address, CPU type (e.g., "Sun SPARC"),
OS type (e.g., "SunOS"), and the name and phone number of the
administrator of the system (for contact if problems occur with the
network).  You can find a good reference on naming computers in FYI 5,
which you can get by anonymous ftp from ftp.uu.net in the directory
/inet/rfc.  Here is the title line for this FYI:

  5     Libes, D.  Choosing a name for your computer.  1990 August; 8 p.
        (Format: TXT=18472 bytes) (Also RFC 1178)

o Edit the /etc/hosts file so it has an entry for your host with its IP
address and an alias for loghost (required by syslog).  Here is an
example of the /etc/hosts file:

	127.0.0.1	localhost loghost
	128.95.257.123	myhost myhost.cac.washington.edu

o If you are using SunOS 5, a file should have been created during your
operating system installation called "/etc/hostname.le0" (where "le0"
is the name of your Ethernet interface, so it may differ from this
example).  This file contains the name of your host and should match one
of the entries in the /etc/hosts file you just created ("myhost", in
this example).

o Edit the /etc/netmasks file and add an entry for the network 128.95 with
a netmask of 255.255.255.0.

o Create a file called /etc/resolv.conf.  Here is an example of what
it should contain:

	domain cac.washington.edu
	nameserver 128.95.120.1
	nameserver 128.95.112.1
	nameserver 128.101.101.101

o For SunOS 5 users, you will need to copy the file /etc/nsswitch.files
to have the name /etc/nsswitch.conf.  Edit this file and change the entry
for hosts to look like this:

	hosts:      files dns

o For SunOS 4 users, you will need to replace some libraries on the
system that handle domain name system (DNS) name resolution.  You can
get replacement libraries by anonymous ftp from the site
ftp.cac.washington.edu in the directory /pub/sun-fix.  Get the file
ReadMe.DNS and carefully follow the instructions there.  (Note for
SunOS 4.1.4 users; the 4.1.3 binaries appear to work fine for 4.1.4
systems)

o Reboot the computer.  The netmask and broadcast address will be set by
the system initialization files.  (For SunOS 4, the command is
"ifconfig le0 netmask + broadcast +" in the /etc/rc.local file.  For
SunOS 5, the command is "/usr/sbin/ifconfig -au netmask + broadcast +"
in the /etc/init.d/inetsvc file.)

You host should now be usable on the network.
