Server
The server (in sw/ground_segment/tmtc/) is an agent that logs, distributes, and preprocesses messages for the GCS and other agents as described in the system overview.
See DevGuide/Server_GCS_com for the communication between the server and the GCS.

Running server and GCS on different hosts
Upon startup the GCS requests the CONFIG message from the server, which contains the URLs to the aircraft configuration files.
Normally these are sent as file URLs, e.g. file:///home/user/paparazzi/conf/airframes/your_airframe.xml.
Which implies that you need the exact same configuration files on the computer where you start the GCS.
Serving XML files via http
Usually the nicer solution is to serve the XML files (flight plan, settings, etc) via http from the host running the server.
To do that, start server with the -http option and set the hostname/ip with -hostname host, e.g.
server -http -hostname 192.168.0.100
and start a http server that serves the contents of the paparazzi directory (Http Server from the Tools menu in Paparazzi Center), or:
cd ~/paparazzi/ python -m SimpleHTTPServer 8889
to check if it works, you can open http://192.168.0.100:8889 in your webbrowser where you should see the contents of the paparazzi directory. Or use netstat to see if 8889 port is opened for listening:
netstat -l|grep 8889
Export KML to Google Maps
It is useful to export Flight information to Google Map. you can show basic flight information in google map cross platform through IP network.
You will need a webserver runing in the GCS computer, see above.
Then in Paparazzi center, execute a session. Pass some parameters to server agent:
server -kml -hostname 192.168.0.100(replace with you paparazzi center IP address)
It's done. Now in any computer in the network, open browser to access http://192.168.0.100:8889/var/aircrafts/(you AC name)/
you will see FollowMe.kml file, open it with Google earth. you will be able to see the real time flight information. the information updated are:
1. AC lat, lon, alt 2. Flight Plan 3. current route
