the probléme is that from the router i can ping every network, but from the pc, if i am in the network 192.168.6.0 for example, i can't rich the network 10.0.0.0;

First, I'd kill off "no ip classless." It probably isn't making any difference in this situation, but it might hurt you later.

Beyond this, the first thing to check is the default gateway on the host you're pinging from. If you can ping everything from the router, and you can't get off segment from a host attached to the router, I always suspect the default gateway on the host first. You can actually test the default gateway setting on the host from the router, by pinging an attached host using the loopback address as a source. So:

7206F#ping

Protocol [ip]:

Target IP address: 10.1.1.1

Repeat count [5]:

Datagram size [100]:

Timeout in seconds [2]:

Extended commands [n]: y

Source address or interface: loopback 0

....

If the pgin fails, the problem is most likely on the host side. If the ping succeeds, then we would need a show ip route off the router (though I don' see how the routing on a single router could really be messed up all that bad--i've seen two routers fail miserably, but never one). :-)
