A 1.1.b Start LUPMIS on a LAN
In an established network environment, e.g. in a LAN at a TCPD office with an experienced network administrator, LUPMIS can run through the network. Databases (MySQL) are accessed on the central server to ensure that all users have the same tabular data, while - for higher performance - GIS image data are stored locally.
LUPMIS has to be installed on the server, following the standard procedure, as explained in the chapter (Annex 1.1). On the workstations (clients), LUPMIS must also be installed the same way.
At the time of log-in, the user decides which data he wants to access, either locally on the workstation or on the LAN. He should know the IP address of the server. Preferably, this is a static address, defined at the server by the network administrator. In LUPMIS, select: LAN: Change...
Then select from the list of addresses in the LAN, starting with 192.168.x.x.
Inside LUPMIS, this list can also be retrieved through Settings > System info.
For security reasons, user name and authorization have to be set from the server. These are then to be used for every log-in from the work station to the server's data.
With this log-in, the user can see and retrieve all database data at the server.

Checking for IP addresses can also be done in Windows at command level through command: cmd /c arp -a
Often, communication to the server can cause a problem. A way to check the integrity of the communication is to 'ping' from the workstation to the server:
If there are still problems, check that MySQL has been started and active (through xampp > MySQL), as explained in the previous Chapter (Annex 1.1.a).
