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.
