Hi, I have two pc's connected to each other by a patch cable : pythia : 158.64.89.41 delphi : 158.64.89.40 But when I try to ping from one pc to the other I receive the error : PING delphi.men.lu (158.64.69.40): 56 data bytes ping: sendto: Network is unreachable ping: wrote delphi.men.lu 64 chars, ret=-1 Output from the ifconfig-command : eth0 Link encap:Ethernet HWaddr 00:D0:B7:BE:58:9A inet addr:158.64.89.41 Bcast:158.64.89.255 Mask:255.255.255.0 inet6 addr: fe80::d0:b7be:589a/10 Scope:Link inet6 addr: fe80::2d0:b7ff:febe:589a/10 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:10 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:100 RX bytes:0 (0.0 b) TX bytes:732 (732.0 b) Interrupt:10 Base address:0xa800 Memory:c8840000-c8840c40 Output from the route-command : Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 158.64.89.0 * 255.255.255.0 U 0 0 0 eth0 Can someone say why it is not working or what I forgot ?
