Question on ping & ethernet on RHEL ES x86_64
581674Mar 26 2008 — edited Mar 27 2008I am not sure why this is happening & decided to take your opinion -- it's purely LIinux/Network issue -- no relationship with Oracle or anything else.
I have 2 AMD64 Red Hat x86_64 machines -- node1 & node2 -- each with 2 ethernet cards --eth0 & eth1.
The /etc/hosts (on both) has 4 entries:
# node1
192.168.0.103 node1.systems.com node1
10.0.0.1 node1-priv.systems.com node1-priv
# node2
192.168.0.104 node2.systems.com node2
10.0.0.2 node2-priv.systems.com node2-priv
The interfaces (on each) have been defined as:
node1
eth0: 192.168.0.103/255.255.255.0/192.168.0.1 (and bound to MAC address)
eth1: 10.0.0.1/255.255.255.0 (and bound to MAC address)
node2
eth0: 192.168.0.104/255.255.255.0/192.168.0.1 (and bound to MAC address)
eth1: 10.0.0.2/255.255.255.0 (and bound to MAC address)
The cat5 connections are through a 5 port switch.
Now, when I ping node1 to node2 and vice versa, it works fine but can't ping between node1-priv & node2-priv -- getting "Destination Host Unreachable"!
Can somebody please help me to resolve this Linux/Network issue?
Thanks.
