There's some progress, but it's not solved yet.
To recap, when I do a net installation, the kernel boots and
then some stuff happens too fast to follow. It does DHCPLISTEN
for a while on an infiniband port (ib0) and the loopback port
(lo). That times out and it all comes to nothing.

I haven't written for a few days. I have tried a few things, with
no success. These include
* Switching to OSCAR 5.2b2 and CentOS 5.2 for the compute nodes.
* Turning off iptables entirely on the head node.
* Using a boot CD instead of booting over the net.
* Editing the image's modprobe.conf

Are you referring to 5.1 beta2? I had to flip a coin to decide
if that name was more reassuring than 5.1rc1. I decided that
an rc sounds better than a beta. If there really is a 5.2,
I haven't been able to find

I take it that heterogeneous here refers to function and not the
hardware because I have homogeneous hardware on my LAN/classroom.

Oh, OK, I see, so you are not reimaging the head node. Then you use
the head node to image the compute nodes. Thusly, if the head node
starts out running Ubuntu, so do the compute nodes? So, OSCAR is
installed over the base distro.

In step 2, "Build OSCAR Client Image", choose IP Assignment Method =

They are different in that Rocks only supports RedHat (and RH
derivatives like CentOS) and maybe Solaris. It uses a RH specific
installation mechanism to install compute node images. Specifically,

OK, then what is a "supported distro?". I thought this meant a distro
to install OSCAR on. So, how is OSCAR different from RocksCluster?

Patrick,
Does your compute node have multiple NICs? If yes, try using the other
one. Sorry, I can't be more definitive.
Two other things:
I would suggest about oscar 5.1 is that you use an older distribution

Hi Erich,
thanks for your hints, after getting really anoyed with the two clients we
tried everything possible, we decided to switch on another node ... and it
works!
So it seem that from 32 nodes we tried the two ones that doesn´t work.

Hi Sylvia,
this is very strange and the only place I can suspect is the network.
On the client node (with interrupted installation) you can use busybox to set
an IP on eth0 and ping addresses. Can you ping the server? Does the server see
the packets? Which interfaces do you see on the clients wit

Hi Sylvia,
I have seen such issues only with nodes which had multiple ethernet
interfaces. The cable needed to be plugged into the other connector.
The e100 driver is usually included in the systemimager kernel, the dhcp
request from the client node shows that you actually do have an eth0

until step 6. Now we try to install the clients with pxeboot.
Everything works fine until the client tries to get the IP Address again
