2 NICs on physical machine
Hello,
I will be working on Centos 6.4 with 2 NIC configuration. One IP will be 192.168.XX.XX and the other 134.XX.XX.XX. Are there any specifics I should be aware of when I enter them in the Network settings. I haven't worked with linux with 2 NICs setup. TIA, TS |
having two nics is not interesting. It's what you're actually doing with them them affects things. You need to give us the full picture if you want advice. Only thing that people seem to always want to do is to have two default gateways. I still have no idea what they think that means.

perfectly logical idea. Well done him. So what's the concern?

The rules of TCP/IP don't change in linux. The issue would be usually a combination of IP address and subnet mask. That should allow IP range choice to correct endpoint within subnet. If it goes outside of subnet then you'd have to add in a gateway address. This may be confusing if both nic's need a gateway. That could be fixed with some settings. Usually internal lan doesn't use a gateway but tell us the exact topology.
Linux versions may put gateway and other settings in different places. It may be automated on some dhcp or may have to have some network manager settings changed. |

as mentioned, as long as the two nics are assigned to two distinct discrete networks and the backup server is configured to belong to the same network as the internal nic than it should work something like this: Code:

It turns out the network guy used a cicso asa (used NAT). I only had to use one physical NIC which is 10.XX.XX.XX. When I am logged in, the browser shows my IP address as 134.XX.ZZ.ZZ (Same iP I used for SSH).
We are trying to get backup to run (our backup server is on 134.XX.YY.YY) |
your backup server is on a public IP? OK now THAT is really really dumb.
But is there an issue here that you need help with or are we done? |
