Ping Problem "Destination Host Unreachable"
I have 2 machines ebdb1 (Oracle VM machine) and aasbanas (Openfiler). ebdb1 has 3 interfaces and aasbanas has 2. Following are contents of /etc/hosts file on both
192.168.1.81 ebas1 192.168.1.61 ebdb1 192.168.1.62 ebdb2 192.168.1.30 aasbanas 192.168.2.11 ebdb1-priv 192.168.2.12 ebdb2-priv 192.168.1.71 ebdb1-vip 192.168.1.72 ebdb2-vip 192.168.2.31 aasbanas-priv Now I can ping ebdb1 and aasbanas from both machines but can't ping ebdb1-priv and aasbanas-priv from eachother and get error "Destination Host Unreachable". Following is some dianostic data. /etc/resolv.conf on both machine has following line. nameserver 192.168.1.1 [root@ebdb1 ~]# cat /etc/sysconfig/network NETWORKING=yes NETWORKING_IPV6=no HOSTNAME=ebdb1 GATEWAY=192.168.1.1 [root@aasbanas ~]# cat /etc/sysconfig/network NETWORKING=yes HOSTNAME=aasbanas GATEWAY=192.168.1.1 NETWORKING_IPV6=no [root@aasbanas ~]# ping ebdb1-priv PING ebdb1-priv (192.168.2.11) 56(84) bytes of data. ....

Where do you connect eth1 of the "ebdb1" to? And where do you connect eth1 of the "aasbanas" to?
|
I'm sorry if I mis-understood your question. ebdb1 is VM on server connected to router and aasbanas is also connected to same router.
|
Any help on this issue will be really appreciated.
|
Can you ping 192.168.2.31 on aasbanas and 192.168.2.11 on ebdb1
|
Just to add to my first message, I can ping to outside world (e.g. google.com)

Ok, I ask again:
Can you ping 192.168.2.31 on aasbanas? |

Do please on aasbanas:
arp -n -i eth1 Post output. Thanks. |

arp: in 2 entries no match found Thanks. |
Do please on aasbanas:
arp -n -i eth0 Post output. Thanks. |

Try to do on aasbanas:
ping -b 192.168.2.255 Post output please. |
It hangs on following
[root@aasbanas ~]# ping -b 192.168.2.255 WARNING: pinging broadcast address PING 192.168.2.255 (192.168.2.255) 56(84) bytes of data. and I get same behaviour on ebdb1 too. |
You know, I would say that interface eth1 doesn't connect to anything. Because it doesn't see anything.
But I have no idea about WM and hope that others from this forum help you. |
