Hi! You have right, I've made a mistake in the presentation of the problem:
the "export DISPLAY=127.0.0.1:0.0" at the second host must be: "export DISPLAY=<FIRST_HOST_IP>:0.0" However only the presentation was bad, the problem is the same. I can ping the first machine from the second. Best Regards Jozsef Kercso >Jozsef, >You example makes no sense at all.
