Hi all!!
i'd like to have a dhcp server for two networks 192.168.1.0 and 192.168.2.0, my question is, which could be the netmask in the server?
i don't want that a segment of the network see the other one. But both see the server.

well, normally the netmask of 192.168.x networks is 255.255.255.0 or in CIDR notation /24.
do you want to physically keep these two segments apart? or just logically?
both is easily possible. if you want to do it physically, just use two nics in the server and let the dhcp daemon listen on both interfaces.
if both networks are logically the same network you will have to seperate both somehow, like letting the daemon know the mac addresses of the machines. keep in mind that this has nothing to do with security, because a machine still can be attached to the network with a faked mac address or a manually assigned ip address.
