The background bit..
I have a Dell PowerEdge 2850 server
on which I am trying to install XEN 3.0.3
The server has 2 built in gigabit Broadcom NetXtreme II Ethernet cards. (Using the
bnx2 module)
I am running Debain, I can boot to
the XEN DOM0 kernel.
I have disabled one of the network cards in the BIOS. (As I
heard that there is a little confusion between dell and Debian
in figuring out which card is which)
I compiled XEN from the sources using the linux-2.6.16.29
kernel
Now here is the strange bit…
When I boot to Dom0 eth0 gets an IP address from the DHCP
server. But when I try and ping that same DHCP server using the eth0
interface, I get "Destination Host Unreachable", (when i
ping anywhere infact - not just the DHCP server).
Ideally I would like to assign a static IP address to the
server, but when I do that in /ect/network/interfaces again I get "Destination
Host Unreachable". (I have double checked and confirmed with another IT
admin working here that I am using the correct config)
I can also run "dhclient" on the peth0 interface,
this again gets an IP address from the DHCP server, but when I try to ping the
DHCP server on that interface I get no reply what so ever.
If i go back into the BIOS, and change which port is
disabled, and then reboot the machine eth1 then gets an IP address from the DHCP
server (just - it takes ages to get one and sometimes fails completely!), you
can then ping places. BUT as i said above I would like to staticly assign
the IP address in /etc/network/interfaces, as soon as I do that, again I can't
talk to anything (ping or otherwise).
Does anyone have any idea why I can get DHCP addresses but
can’t ping anywhere? I don’t have any sort of firewall running and
ICMP packets are allowed on the network.
This is my first Xen install and I have fairly intermediate knowledge
of Linux and Debian.
Thanks in advance.
