I was able to load a more current version of the RH kernel, etc. and
displays and response look much better. qeth/qdio appears to be in this
kernel, IFCONFIG diplays eth0 with the data I entered, but I still can't
get to the Linux guest. Admittedly, networking isn't my strong suit. I've
talked to the network guys and they have helped me as much as they can. We
both are confused by some of the terminology. I need define my network
environ a little more and all of this is behind a firewall. We have a
z800 with two osa express cards, therefore a total of 4 ports. Port
0(card 1) has 10.140.1.22 as it's ip addr Port 0(card 2) has 10.140.1.24.
When we first installed the box I tried to put both of these on card 1,
port 0 and port 1 respectively. I never could get it to work. Well come
to find out and I may have the terminology wrong, you can't have two ip
addrs with the same subnet on the same card. When I moved 10.140.1.24 to
card 2, port 0, my original network started to work. Right or wrong it is
working. However, if it is wrong, please tell me as I don't want to run
into problems later on.
To continue, I read some where that Linux should or must be installed in
it's own subnet. I seem to remember this from the early days but had
forgotten it. Is this still true? Thus the ip addr of 10.140.2.x
Back to the linux config: I've listed below the prompts during network
config when I start linux.
Enter the IP address of you new Linux guest: 10.140.2.40 (No problem with this one)
Enter the network address of the new Linux guest: 10.140.2.0 (I'm not 100% sure of
this answer, from looking at countless examples, the
4th
octet
should be 0(zero).)
Enter the netmask of the new Linux guest: 255.255.255.0 (No problem with this one)
Enter teh broadcast address for the new Linux guest: 10.140.2.255 (Not 100% about
this one either, most examples code it this way i.e., the
4th
octet is 255)
Enter the default gateway: 10.140.2.254 (This is where I get confused. a) should it
be 255 instead of 254? If so,
is the reply to the previous question
wrong? or b) does it mean the
default gateway for the rest of my network. In this case it would be
10.140.1.254 (but the 254/255
question still lingers).
Enter your DNS server(s), seperated by colons( : ): 162.133.1.19:162.133.1.22 (This
one isn't clear to me, i.e., does it want the DNS server name or
the ip addr. I assume ip addr(s). It doesn't fuss about it. However,
I've never entered the DNS server name(s)).
Enter your DNS search domain(s) (if any), seperated by colons ( : ): vm.llic.com
(I'm not sure about this one either, however it has to be one of two
replies
(for us) vm.llic.com or llic.com. I have tried llic.com and it
doesn't seem
to make a difference)
I've included a new console listing below.
Again, TIA
