NAME
nd - network disk control
SYNOPSIS
I
etc/nd
I
command)
DESCRIPTION
58
The nd command controls the network disk service of the kernel as described in nd( 4p). A single
command may be given on the command line; if none is given then the standard input is read .for
a list of commands. Typically, the file /etc/nd.local is used for input. Lines beginning with
':f/:'
are considered to be comments.
The available commands are:
uaer h08tname hi8unit mydev myolf myBize mylunit
For the client h08tname transform incoming requests for hi8unit into server device mydev
at ofl'set myolf and size mY8ize sectors. /dev /ndlmlllunit provides a local name for this
disk "subpartition", If m1l8ize is "-1", then this user unit is equivalent to the entire
filesystem partition mlldev (no "subpartioning"
is
done.) If mylunit is "-1" then no local
name is needed for this user unit; this is usually the case with a swap unit, or a unit
represent~d by an entire filesystem. If h08tname is a numeric zero, hi8unit refers to a
public unit.
ether h08tname ether_addr
I
mazpack8
J
The ether command associates an Ethernet address ether_addr with the client hoBtname.
This information
IS
required in order for a client to learn his Internet address when it
boots - nd provides the Internet address for h08tname based on the Ethernet address
received in a boot request. The Ethernet address is given
38
siz hex bytes separated by
colons, e.g., 8:0:20:1:1:a3. At least one previous uler command must have been issued
for the client. The mazpack8 option may be given to set the maximum number of pack-
ets that the server will send to the client before requesting an acknowledge. The default
is 6; it should suffice un!ess the client Ethernet interface is very slow.
veralon versionnumber
IOD
• off
clear
The verllon command gives the level of configuration of the server. Occasionally the
need arises to reorganize or reload the diskless partitions. Since the clients will rewrite
locally cached blocks, they must be kept from writing their filesystems until they reboot.
Before such a reorganization occurs, the system manager should warn diskless users to
save files and halt their machines. Modification of the partitions should occur with the
disk server oft. After modification is complete, versionnumber should be incremented to
force users to reboot.
Start!! the network disk server.
This command should be issued after all Uler, ether,
and verlloD commands .
Stops the disk server until a subsequent
10D
command.
Stops the disk server and clears all uler and ether information.
lerverat h08tname
Systems with disks may use the .erverat command to specify a disk server if they wish
to user a network disk in addition to their locally attached disk. Even then, this com-
mand is only necessary if they wish to use a public network disk or if they wish to change
network disk servers.
