DHCP PXE and Gateway Double Entry

dragonfly-uk · 03-09-2013, 07:54 AM

I have setup a OpenMediaVault (Debian) Server which is acting as a PXE Server. Off which I am booting an Ubuntu 12.04 Server. Both these are located on a wireless link\bridge to my office and the router(gateway)

Both servers boots fine, and I can ssh into either server as expected from my office accross the wireless link. However whenever I try to anything internet related I don't get a connection to the internet. I figure this must be related to the gateway. So I have pinged the gateway, and that is responding as expected.

One the debian PXE server the route table is

Code:

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.1.0     0.0.0.0         255.255.255.0   U     0      0        0 eth0
0.0.0.0         192.168.1.254   0.0.0.0         UG    0      0        0 eth0

However on the ubuntu server booted over PXE the route table is

Code:

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
0.0.0.0         192.168.1.254   0.0.0.0         UG    0      0        0 eth0
0.0.0.0         192.168.1.254   0.0.0.0         UG    100    0        0 eth0
192.168.1.0     0.0.0.0         255.255.255.0   U     0      0        0 eth0
192.168.1.0     0.0.0.0         255.255.255.0   U     0      0        0 eth1

eth1 is a second network interface that is not in use, but notice the double entry for the gateway, is this right??

Can anybody help me get these 2 machines talking to the gateway and the internet correctly?

Thanks

Thinking further about this I have checked the gateway, and it has both the "clients" listed as connected. The Ubuntu machine has the correct hostname, but the debian machine is showing a hostname of "MSFT 5.0"
