arp problem in pinging host
Hello,
I have pc hostA with 192.168.1.100 connected to pc R1 with eth0:10.1.1.1 and eth1:192.168.1.1 via crosscable when i ping from hosta to R1 request packet goes to R1 but R1 generates packets with srcip=0.0.0.0 and destination ip of R1's eth1=192.168.1.1 and hosta unable to receive reply packet from R1. But if i ping from R1 to hosta packet always goes to hosta and receives reply at R1. What can be the reason is that arp cache problem or what else? When i send ping packet to R1 from hostA, the arp analysis on my both Linux machines shows that when i did arp -a on hosta and found output that R1(192.168.1.1) at <incomplete> on eth0 and on R1 nothing is displayed. When i send ping packet to hostA from R1, the arp analysis on my both Linux machines shows that when i did arp -a on R1 and found output that Address HWtype HWaddress Flags Mask Iface hosta ether 00:08:F1:43:62:91 C eth1 and on hosta Address HWtype HWaddress Flags Mask Iface R1 ether 00:08:F1:43:61:C1 C eth0 whats wrong in hosta linux machine? |
I don't think that arp is where your problem is. My guess is that you have some routing issues, probably on R1. Could you post the result of route -n on each computer?
