DISKLESS_SETUP(8)DISKLESS_SETUP(8)NAMEdiskless_setup - set up a server for diskless/dataless clients
/sbin/diskless_setup -l interface -r rdir [ -o ] [ -s size ] [ -h addr
] [ -m netmask ] [ -a srv_addr ] [ -g gateway ] [ -x vmunix:offset ]
Diskless_setup sets up files on a server to handle a diskless or data‐
less client workstation. Based on the arguments, it fills in all the
fields of an nfs_diskless structure for that client and saves it in
either a separate file or in the "vmunix" executable image for that
client at the appropriate byte offset. See diskless(8) for an overview
of running diskless or dataless clients.
The name of the network interface to be configured on the client
at boot time so that it can communicate with this server. (eg.
The pathname of the root directory of the root file system for
-o Write the nfs_diskless structure to standard out so it can be
piped to another process in a shell script.
This client is to run diskless (ie. swapping to this server), so
create a swapfile of size 512 byte blocks for this client.
The internet address for the client's net interface specified
with -l. (The default is the first address returned by gethost‐
byname(3) for this client host.)
The subnet mask for the client's net interface specified with
-l. (The default value is determined by the interface's address
The internet address of this server. (The default is the first
address returned by gethostbyname(3) for this server.)
The default gateway for the client to use to get to this server.
This should only be specified if the client is not on the same
LAN as the server. (For performance reasons, this should be
avoided whereever possible.)
Write the nfs_diskless data structure into the "vmunix" file
specified at the specified byte offset instead of a separate
file. The executable file and byte offset are specified sepa‐
rated by a colon. (eg. vmunix.pmax:654322)
Examplesdiskless_setup-l le0 -r /diskless/pmax_root blondie
Setup the client "blondie" as a dataless workstation (ie. swapping
locally) communicating with this server via. "le0" and using the root
file system at /diskless/pmax_root. Blondie is attached to the same LAN
as this server and the first internet addresses returned by gethostby‐
name(3) are appropriate for both the client and server addresses.
diskless_setup-l wd0 -r /diskless/i386_root -h 22.214.171.124 -m
255.255.255.0 -x vmunix.freddy:345672 freddy
Setup the client "freddy" as a dataless workstation communicating with
the server via. "wd0" and using the root file system at /disk‐
less/i386_root. Freddy's internet address for "wd0" is 126.96.36.199
with a subnet mask of 255.255.255.0. The filled in nfs_diskless struc‐
ture is to be written into freddy's executable kernel called "vmu‐
nix.freddy" at byte offset 345672. (the byte offset is normally found
using diskless_offset(8) )
diskless_setup-l qe0 -r /diskless/uvax_root -s 20000 -a 188.8.131.52
Setup the client "bob" as a diskless (ie. swapping to the server) work‐
station ccommunicating with this server via. "qe0" and using a root
file system at /diskless/uvax_root. The swap file on this server is
20,000 blocks and the address w.r.t. "bob" of this server is
/var/diskless/setup.<client_hostname> output of this command
/var/diskless/swapfiles/swap.<client_hostname> swap file for client
There is no capability of setting up diskless clients with remote swap‐
ping on a separate server than the root file system.
