The mapping from DTE address to Ip address required by the X.25 Network Server,
xnet, can be provided locally, by a file stored in Flash
memory, or remotely by an X.25 Map Server. X.25 Map Servers are available for both
Windows and Unix platforms. The Windows server is laygomap
which implements a Windows service. The Unix server is laygomapd
which runs as a daemon. Regardless of the platform, it is recommended that the
server be run from its own directory which contains the executable and map and log
files. The server will load the map file called laygomap.db and the
(optional) node state file, laygonode.db (see below), from it's current directory.
It also creates a logs subdirectory in which it writes its daily log files.
To install laygomap as a service, create a directory
on a local drive and copy laygomap.exe into it along with
the map file and (optional) node state file.
Open a Command Prompt, change to that directory, and execute the command:
laygomap -install
The default is for laygomap to start automatically when the system boots. To configure manual starting of the service, enter:
laygomap -m -install
To start the service after installation, enter:
net start laygomap
The service can also be started, stopped and configured using the Windows Service Manager.
To configure laygomapd to start when the system boots,
enter the following line in /etc/rc.d/rc.local:
cd /usr/laygo/laygomap ; laygomapd
This assumes that laygomapd is installed in
/usr/laygo/laygomap.
The laygomap.db file maps normally DTE addresses to IP addresses.
In place of raw IP addresses, the node names of the PXSs can be used with a
node state file, laygonode.db, mapping node names to IP addresses.
If used, the node state file can either be built manually or the PXSs can be
configured to register their node name and IP address with the map server dynamically.
In the latter case, the map server will automatically create the node state file.
