Hey guys - Here's a
more detailed proposal on the network configuration.
First - re: network
addresses. I'm assuming we will NOT be using DHCP.
- It tends to play
havoc with some server software/frameworks.
- If we want
multiple names for the same system, it doesn't work well. The reason this
is important should be clear by the end of this message.
The down side is
that everyone must configure the network on their systems with fixed IP
addresses. I'm going with the 192.168.x.y proposal from
First, "x" depends
on the alphabetically sorted company name:
X - company
suggested system naming I now recommend setting "y" as
Y - demo
So, for example,
the RSA portal system can be found at IP address
At a minimum, each
company will have 4 entries. This assumes that the system names are
actually set to "portal", "application", etc. If the systems where
these demo functions are hosted really have different system names than
those used above, then we just need to add additional entries for those
addresses. For example:
philpott-lap.rsa.com # actual
system name where the portal runs
application.rsa.com # RSA content
# actual system name where the application resides
# RSA artifact receiver host
# the artifact receiver is also the content provider host
responder.rsa.com # RSA SAML
SOAP binding responder host
philpott-lap.rsa.com # the SAML
responder is also on the portal system
I will put together
a complete etc/host file using the default settings above. If folks
want additional entries for the specific IP addresses, you'll need to send
me the IP addresses and machine names that you'll be using. Please use
machine.company.com # any comment you want
The next issue is
whether to use a DNS server or individual etc/host files.
There are pro's and
con's to using an etc/host file. Pro's - easy to modify, no DNS system
to manage, individual systems don't have to have their network config
changed to account for the DNS server. Con's - easy to get out of
synch, changing the file means updating it on all systems (and we'll have a
lot of systems).
My preference would
be to use a DNS server. I've asked our comm/IT group to set one up for
me on a laptop so it will be easy to take out to the show in SF. It
looks promising, but if they decide they can't do it for me, I'll either
need another company to step up to the plate and bring one properly
configured, or we'll have to go with etc/host files. I'll let you know
when I hear definitively from them. The advantage of the DNS server is
that there's just one place to update and all systems can take advantage of
Does all of this
make sense to folks?

Subject: [saml-dev] Questions about dry
I have a few questions about the dry run, which I
need to secure the right facilities at Sun. My apologies that this has not
been confirmed yet, but being out of the country and trying to
coordinate it make things difficult.
Philpott has already asked several questions, but I still haven't seen any
replies. PLEASE review these
questions, which I have inserted below in
case you no longer have it:
Hey folks - I'm lining up
network access for the dry run. I've asked them to allow http, ftp, email,
through the firewall. Anything else?
1.Do we want a DHCP
server set up for the local network?
2.What about a DNS server? I
would think it would be easiest to just configure an etc/hosts file that we
share, but I thought
I'd ask. I'm not sure I'll have time to configure a system for this
here, so I would probably need
someone else to step up to the plate.
3.Regardless of whether
we want DHCP, I assume a bunch of the boxes will need static
addresses. We should
agree on ranges of address for each company to
use. Someone want to propose something?
propose something for address ranges, but have seen no reply to that either.
Here is that proposal again for your
What about a netmask of
255.255.255.0 and 192.168.x.y where:
x would range from 1-N (N being number of
participants, assigned in alphabetical order)
y would be 1-M (M being the number of machines a
Additional information that I need includes:
many people from each company are planning to attend?
- How many
machines will each of you bring with?
- What would you expect to be
trying to be pushy at all, but without input from all participants on these
questions and issues we can't make the
necessary progress. If someone
wanted to volunteer to create a network diagram that shows all participants,
machines and any other equipment that would be great.
be putting together an agenda sometime today or over the weekend for the
call this next Tuesday. Feel free to
send input. I'm leaving Munich for
Paris at noon and just can't do it any sooner.
