XDMCP from a client behind a router
 
Hi,

I have a local network with a server, a client and 3 laptops which are connected through a router (Linksys 610N). The server is configured to distribute the kdm login screen to others and has an IP address of 192.168.0.10 - and from the client which has an IP address of 192.168.0.11 it works fine to use XDMCP. But for laptops connected through the router (IP 192.168.0.12 for outside and 192.168.1.1 for laptop network) it doesn't work.
The laptops are configured fine and when using one in the 192.168.0.x network XDMCP also works for the laptops.

Is it possible to get the login screen from the server also for laptops in the 192.168.1.x network?


Thank you for your help!
Marcus

i think XDMCP uses IP level broadcast to find the server and then show the login screen.
By networking rules router blocks layer 3 broadcasts.
so you may have to configure the clients to use specific query instead of broadcast query. this can be done using gdmconfig
or kdmconfig at your client side. nothing needs to be changed on the server side. Once this is done, across the router
and also in the same LAN the XDMCP will work.

Thanks for your answer!
But it's the same even if I query the server directly.
Could it be that the server opens some new connections to the client which wouldn't be possible to receive behind a router?
