When the Branch Server connects to the Administration Server, it logs into the LDAP
directory, accesses the configuration parameters for its registered Point of Service ter-
minals, and stores the information locally as ASCII configuration files (
config.
MAC
)
in the
/srv/tftpboot/CR
directory. At boot time, each Point of Service terminal
connects to the Branch Server over TFTP and loads its associated
config.
MAC
file.
There is no need to manually create the Point of Service configuration files. When a
new Point of Service terminal comes online, its configuration file is automatically cre-
ated from LDAP entries on the Administration Server.
For more information on this process, see Section 7.7.3, “The hwtype.
MAC
File”
(page 100) and Section B.2, “Core Script Process” (page 206).
To modify a Point of Service configuration file, you must modify the Point of Service
terminal's entries in LDAP and then run the
posAdmin --updateconfig
command.
For more information, see Table 10.1, “posAdmin: General Command Line Options”
(page 131).
The format of the
config.
MAC
file is as follows:
IMAGE=

image
;
version
;

;
bsize
;compressed,...,
SYNC=

The following list provides a detailed description of each parameter in
config.
MAC
and its variables.
config.MAC Configuration File Parameters
IMAGE=
Specifies which image (
image
) should be loaded with which version (
version
)
and to which storage device (
device
) it should be linked.
Multiple image downloads are possible, but the first listed image must be the main
system image. If the hard drive is used, a corresponding partitioning must be per-
formed.
