NETSVC(1M) Domain/OS SysV NETSVC(1M)
NAME
netsvc - set or display network services
SYNOPSIS
/etc/netsvc [options]
DESCRIPTION
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.
-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 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 startup, the number of network servers is 1.
If this node is a network partner for diskless nodes, has an HP
Series 6300 Model 20GB/A Optical Disk Library System, or has
several remote file users, their performance 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
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 0.
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.
NOTE
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.
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 can decrease the number of servers only on nodes containing
an HP Series 6300 Model 20GB/A Optical Disk Library System. Otherwise,
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.
EXAMPLES
