NETSVC (NETWORK_SERVICE) -- Set or display network services.
usage:  NETSVC [-A|-N|-L|-R] [-P [n]] [-S [n]] [-NET [net_id]]


FORMAT

  NETSVC [options]


  NETSVC sets or displays the network services that this node will perform.  All
  changes take place immediately.


OPTIONS

  If no options are specified, NETSVC displays the network services allowed  for
  this node.

  Default options are indicated by "(D)."

  -N                  None  --  Disable  all  network  services  and  physically
                     disconnect this node from the network.

  -L                 Local -- Allow only network requests  originating  at  this
                     node.

  -R                  Remote -- Allow only network requests originating at other
                     nodes.

  -A           (D)   All -- Allow both locally and  remotely  initiated  network
                     requests.    (The  size  of  the  remote paging pool is not
                     changed.)

  -S[ERVERS] [n]
                     Servers -- Set the number of network servers to run on this
                     node.  At system start-up, the number of network servers is
                     1.  If this node is a network partner for diskless nodes or
                     has several remote file  users,  their  performace  can  be
                     improved  by  increasing the number of servers. If n is not
                     specified, the maximum number of servers (3) is used.

  -P [n]             Pool -- Set local memory pool size.  Network page  requests
                     originating at remote nodes may not use more than 'n' pages
                     of the local node's memory.  If n is not specified, all  of
                     the  local  node's  memory  is  eligible  for  remote  page
                     requests.

  -NET [net_id]
                     Network  ID  -- Set or display network ID.  Use this option
                     to change or examine the ID of the  network  to  which  the
                     node  is  attached.  It  affects only the node at which you
                     type the command, not the rest of the network.   Specifying
                     a  hexadecimal  network  ID changes your node's network ID.
                     Using -NET with no argument forces NETSVC to  display  your
                     network ID even if it is set to zero.

                     This  option  is  useful  only  when  there are no internet
                     routers active on the  node's  network.  Routers  give  the
                     network  ID  to  nonrouting nodes every 30 seconds, and may
                     override the network ID you specify with this option.

                     CAUTION: If the network ID you set with -NET  differs  from
                              the  network  ID  used  by  other  nodes  on  your
                              network, your node may not be able to  communicate
                              with those other nodes.

  CAUTION: Be  careful  when revoking network access with -N or -L.  Remote file
           users may have problems, and writable files may be damaged.  If  your
           node  was  the  network  partner  for a diskless node, that node will
           crash when your node leaves the network.

           Use the -S option carefully.  Although you can increase the number of
           servers,  you cannot decrease it. The only way to return to a smaller
           number of servers is to reboot the node.  Also note  that  increasing
           the number of server processes decreases the number of user processes
           allowed.  When you run NETMAN, the number of servers  increases  from
           one  to two.  If the number of servers is already two or greater when
           you start NETMAN, it will not increase further.


EXAMPLES

    $ netsvc
    Network operations allowed: ALL
    Number of network servers: 1
    Remotely initiated paging pool limit: NONE
