try typing in as root "route add -host 192.168.0.1 eth0" on the notebook, check the routing table and netmask on each machine. if the netmask s wrong you can get some very strange effects. you can check if this is the problem by changing the ip address of the notebook , say to 10.0.1.2 put a route in from the main pc "route add -host 10.0.1.2 ethx" where x is the port linked to the notebook. and on the note book " route add -host 192.168.0.1 eth0" flush out any other routing just to test everything. If that works in both directions , change back to the domain of your choice and look very carefully at the netmasks on both machines. you can delete unwanted routes from the command line "route del -net 192.168.0.0 netmask 255.255.0.0 eth1", thats just an example , again make sure the netmasks are correct. if you check everything out from the console command line , none of the permant routing will be lost, just what you type in , if you reboot HTH richard

Yes there is a lot of SHerlock Holmes in it ;) OK, I've spent another 3 hours, even reinstalling the whole desktop pc. It was a fresh installation anyway. I bought a new cross-over cable. I borrowed 2 other NICs from my company, Once again: Desktop has: eth0 10.0.0.10 which goes through ppp0 to the dsl modem. eth1 192.168.0.1 Io 127.0.0.1 eth0 can ping the Internet, and ping both other devices eth1 can ping both other devices both ethx can ping themselves Notebook has: eth0 192.168.0.2 Io 127.0.0.1 eth0 can ping Io and ping itself But: Notebook cannot reach any other destination apart from own eth0 and own Io Desktop cannot reach neither notebook address. BTW: Firewall is absolutely off and security is set to "cracker's delight" on both machines. I'm not yet bothering about internet access sharing and forewarding and masquerading, I'm just trying to get both machines to see each other. Oh, it has nothing to do that the two screens are pointing in different directions, has it? ;-)) BTW: I had everything running with a 8.o installation with the same hardware! No more ideas.....
