         /opt/SUNWut/sbin/utadm  -c
    
         /opt/SUNWut/sbin/utadm    -d    interface-name       [    -d
         interface-name ]  ...
    
         /opt/SUNWut/sbin/utadm  -f
    
         /opt/SUNWut/sbin/utadm  -n

    DESCRIPTION
         The utadm command manages the private network and DHCP  con-
         figuration  for  the Sun Ray interconnect. It configures the
         name lookup, host, network, netmask, and DHCP database files
         so  that  Sun  Ray  appliances can be connected to a central
         server host over one or more private subnets.   One  of  the
         following  option  flags  must be specified: -a, -c, -d, -f,
         -n, -p, or -r.  The  command  must  be  run  with  superuser
         privileges.
    
    OPTIONS
         The utadm command provides a  way  to  manage  the  Sun  Ray
         private interconnect.
    
         -a    Configure   the   network   interface   specified   by
               interface-name  as  an  Sun  Ray  subnetwork.  In  the
               default case, an available private subnetwork  address
               is   selected   from   the   range   192.168.128.0  to
               192.168.254.0. If the subnet selected is  192.168.N.0,
               entries  for  the  hosts, networks, and netmasks files
               are generated using the hostname(1) of the  server  as
               follows, where IF is interface-name:
    
               File              Entry
    
               /etc/hosts:     192.168.N.1  hostname-IF
    
               /etc/networks:  SunRay-IF    192.168.N.0    SunRay
    
               /etc/netmasks:  192.168.N.0  255.255.255.0
    
               Once  these  entries  are  established,  the   network
               interface    is   activated   as   hostname-IF   using
               ifconfig(1M). If the interface is already up and  con-
               figured,  the  user will be given the option to bypass
               configuration of the network interface and  only  con-
               figure  DHCP  on the interface. This allows configura-
               tion of a Sun Ray interconnect on the  primary  inter-
               face  of  the server. IP addresses on the Sun Ray sub-
               nets  are  managed  using  the  DHCP  protocol,  which
               requires  the addition of several macro entries to the
               dhcptab(4) table to control parameters on Sun Ray sub-
               nets. It is also possible to bypass DHCP configuration
               by entering 0 as the first unit address when prompted.
               The pntadm(1M) command is also used to create the pool
               of available IP addresses for assignment  to  Sun  Ray
               appliances.  Once  the  interface  is  configured  and
               activated, utfwadm(1M) is invoked to add  the  current
               version of the firmware to the DHCP macros for the new
               network. The user is prompted for approval of all  the
               default options, and may change them as desired.
    
               The -a option implies the -c  option  if  the  initial
               configuration has not yet been performed.
    
         -c    Initialize the basic configuration files for a Sun Ray
               interconnect  without setting up any subnetworks. This
               involves making sure that the network  database  files
               and   framework   for  DHCP  exist,  and  setting  the
               /etc/nsswitch.conf file so  that  network  information
               for  the  local Sun Ray subnets is obtained from local
               files.
    
         -d    Delete the network interface specified  by  interface-
               name  from the list of configured Sun Ray subnetworks.
               The specified interface must have been previously con-
               figured using the -a option.
    
         -f    Takes this server offline, which prevents the creation
               of  new  sessions  on  this server when it is within a
               failover group. Existing sessions will not be  killed,
               but load balancing will not select this server for new
               sessions.
    
         -n    Bring this server back online.  This  restores  normal
               operation  of the server and allows new sessions to be
               created on this server.
    
         -p    Print the current Sun Ray interconnect  configuration,
               showing for each interface the hostname, network, net-
               mask, and number of IP addresses assigned to  Sun  Ray
               appliances by DHCP.
    
         -r    Unconfigure all active Sun Ray interfaces  and  remove
               all Sun Ray entries from the configuration databases.
