There will be a call tomorrow (Wed 4-22) at 9AM ET for authors and potential authors of NSI architecture document sections. The call will be to discuss who is able to participate in creating initial versions of sections of the document, and how to handle multiple versions while the sections are being created and edited.

Comments on draft OGF protocol description requested
by Ralph Niederberger 22 Apr '09

22 Apr '09

Dear all, my name is Ralph Niederberger. I am one of the chairs of the FVGA-WG at OGF. We are currently investigating in designing a new protocol for dynamic opening of ports within firewalls by authorized user applications. Sorry for crossposting to all of the infrastructure-area mailing lists, but I would like to get feedback from all of you concerning a draft protocol we are just preparing within our group. And because our area-directors did not provide me with information on an infrastructure-area mailing list, where I could send it once, I had to send it to all RG/WGs The draft description I have appended to this email. It would be very helpful, if you could comment on this proposal, so that the Firewall Virtualisation for Grid Applications - Work Group can work on your comments at the next OGF meeting. We know that there are many other developments, which already have tried to solve this issue, but have not seen any solution, which is widely used and/or provides a similar easy to use interface and broad range of usability. Our intention is to get as much as possible feedback, so that we can decide as soon as possible, if the direction we are going is the right one or if we have missed anything important. Dependent on your feedback, we would like to go for this solution or change the draft accordingly. Then we would like to start the following steps in parallel: a.) Getting in touch with IETF for standardization issues. b.) Implementation of a first very limited prototype (showing that it works as suggested). Step b could be separated into different parts: b1.) prototype implementation for linux iptables b2.) prototype in close cooperation with a Firewall developer (-> a first FiTP aware firewall). Anyone having contact to these guys would be fine. b3.) Communication prototypes for out of band signalling, i.e. for firewalls which are FiTP unaware. So the auth server has to start a subroutine for firewall configuration (via CLI, special firewall managament software, https, ...) b3 could be done for several firewall systems, e.g. Cisco Pix, Checkpoint, ... Here we would need experts having access to those kinds of firewalls within test environments. Next steps are very dependent on the outcome of steps a.) and b.) above. I would like to thank you all in advance for your feedback. best regards Ralph Niederberger -- *************************************************** Ralph Niederberger Juelich Supercomputing Centre Institute for Advanced Simulation Phone: +49 2461 61-4772 Fax: +49 2461 61-6656 E-Mail: r.niederberger(a)fz-juelich.de WWW: http://www.fz-juelich.de/jsc/ JSC is the coordinator of the John von Neumann Institute for Computing and member of the Gauss Centre for Supercomputing *************************************************** Forschungszentrum Jülich GmbH 52425 Jülich Sitz der Gesellschaft: Jülich Eingetragen im Handelsregister des Amtsgerichts Düren Nr.

Fwd: [Fwd: Re: Architecture strawman]
by John Vollbrecht 10 Apr '09

10 Apr '09

Attached is revise strawman doc. If Joe and Chin and others can edit it further and send it back to me that would be good. I would like to discuss it further on Wed at our call. I suggest that everyone look at it and if they have edits or suggestions send them to me or to the list. I will try to update the doc as soon as possible. I have been out a lot for the last week, my father in law died on wed after a couple weeks of fairly intense events and issues that I have been mostly supporting my wife with. The interment will be next Thursday, so there will be a couple more days then. That is why I haven't been more active in dealing with the edits. I look forward to the discussion next wed.
