mop_mom(8)mop_mom(8)Namemop_mom - MOP down-line/up-line load listener
The command listens for down-line load and up-line dump requests on
behalf of your local ULTRIX node. The command, is usually included in
the file. When a down-line load or up-line dump request is received
from a target node, spawns the loader, to process the load request.
To process a load request, the loader requires the name of the load
file. During a down-line load process, the target system can either
request that the loader search the nodes data base for the name of the
load file, or it can specify an image name as part of its request. If
the target system specifies an image name, the loader does not search
the data base for the file before processing the load request.
If no absolute pathname is associated with the image file name, the
loader searches for the file using the primary default path, If the
image file is not in it uses the secondary default, The names of the
files in must be in lowercase with a extension. Otherwise, the loader
interprets the file specification literally without appending the
extension. For example, if you give the loader the file name it
attempts to open a file with an exact match.
The loader must have the following information before it can accept and
process a load request:
Ethernet Physical Address
If the name of the image is not in the program request message
itself, the Ethernet physical address of the target node must be
specified in the nodes data base entry for the requesting target
node. For further information, see The same is true if the envi‐
ronment variable, LOADUMP_SECURE is enabled.
Image File Name
The loader must be given the name of the image file to down-line
load. If the image file name is specified in a target node's
down-line load request, then the loader uses that file. Other‐
wise, the file name must be defined in the requesting node's data
base entry. For further information, see
Dump File Name
The loader must be given the name of the dump file that will con‐
tain the up-line dump image of the requesting node's memory. The
dump file name must be defined in the requesting node's data base
entry. For further information, see
Note that the System Manager can force the loader to search the nodes
data base, even when the target node specifies a file name. The loader
verifies that an entry exists for the requesting node before proceeding
with the down-line load. Any file name specified in the request mes‐
sage supersedes a file name specified in the data base.
To force the nodes data base search, use the following syntax before
# setenv LOADUMP_SECURE on
To permanently enable this feature, enter the following line in the
file after the section on local daemons:
The command is installed in The down-line loader, is installed in
The file is the primary default pathname for all image files and is the
secondary default pathname. The names of the image files in must be in
lowercase with a extension.
This command is usually included in the file, which causes to listen
for down-line and up-line load requests.
The command does not turn on network devices. When executed, it lis‐
tens only on those devices that were previously started by network
utilities such as or DECnet Generally, you can ensure that performs
properly by putting it at the end of your rc.local file.
Currently, only supports RSX, a.out, and VMS downline load images.
Primary default pathname for all image files
