2 separate networks, only one has a gateway, routing is not working
I have a system (RHEL 5.3) serving meta data for a StorNext SAN on one port (eth0 10.0.0.0/24 with no gateway) and connecting to the "house" network (internet surfing and remote access) through the other (eth1 10.10.10.0/24 via 10.10.10.1).
When The NICs are connected everything is happy and works correctly, however, once you unplug eth1 (not ifdown, just unplug the actual cable) the StorNext software stops responding. Thinking this is a routing issue I looked at the route table: Code:
#>ip route show Code:
#Set up the first subnet's routing table (we'll name it 70) |
Looks like it was a DNS issue!
At 1st we hadn't noticed that when the software was getting an error the two systems could ping each other without error. We added an entry in /etc/hosts giving the IP address twice:
Code:
# Do not remove the following line, or various programs |
