File staging extension
by Andrew Grimshaw 07 Nov '07

07 Nov '07

All, Today we discussed which URI's to support in the proposed file staging extensions. Particularly for SC07. I suggest the following URI's ftp http mailto because they do not require us to address the issue of delegation in advance of SC07. (As I said at the last OGF I do not think the delegation approach in the delegation proposal is a good idea). Of course I think ByteIO/RNS is a good idea - but I don't expect much support for that. (We support it.) Note that there exists a standard format for an ftp URI which includes username/password. Therefore one could include the information in the JSDL document without any need for delegation. (I do not know gridFTP well, perhaps it supports a similar set of uri options, eliminating the need for passing a delegated credential.) On the other hand if we choose to support gridFTP, scp, or any other protocol that requires a delegated credential, then we must also agree on a delegation strategy . with a potential need to replace it later. (By the way, we are not familiar with a standard URI format for scp.) Right now we (the Virginia Genesis II group) support ftp, http, mailto, and RNS with delegated credentials (not via the same mechanism Marty is proposing). A

Compliance tester with X509 support
by Paolo Andretto 07 Nov '07

07 Nov '07

Hi all We (CREAM-BES team) are facing several problems with the new authentication support of the compliance tester based on X509 certificates. If we undestand correctly the client uses a self-signed certificate for the authentication and the gLite security infrastructure (trustmanager, LCAS/LCMAPS) seems not to allow that kind of credential. Is it possible for the client to have its own certificate signed by the certificate above (acting in this case as a CA certificate)? Thanks Paolo

HPC Base Profile experiences document
by Glenn Wasson 01 Nov '07

01 Nov '07

All, Attached is a draft of the HPC Basic Profile experiences document that we have been working on as part of the OGF document process. Please read as we will be discussing this document on the call tomorrow. If you are interested in contributing to this document, I need 3 things: 1. corrected / additional information for the implementers table in section 2. I did not know the exact software stack for everyone listed there and it is possible that other groups have done interop testing that I am unaware of. 2. does section 3 reflect your experience? 3. did you encounter any issues and resolutions that you think should be added to section 4? Thanks, Glenn

HPC Basic Profile Compliance Tester support for client authentication using X509
by Glenn Wasson 31 Oct '07

31 Oct '07

All, I have added support to allow the HPC Basic Profile Compliance Tester to identify clients via X.509 (instead of just username/password). The service's URL is https://opteron4.cs.virginia.edu:45885/FormServerTemplates/HPCBasicProfileCo mplianceTester.aspx. On the left hand side, you will now see a radio button labeled "Client authentication". It has 2 options, "Username/password" and "X.509". If you select "Username / password", the username and password boxes will function as before. If you select "X.509", then those boxes will be disabled and the compliance tester will attempt to make a mutually-authenticated SSL connection to your service. The certificate that the compliance tester uses is available at http://www.cs.virginia.edu/~gsw2c/HPCBasicProfileComplianceTesterCert.pem. If you want to test your service's X.509 authentication, download and install this cert where ever it needs to go so that your service will trust the HPCBP Compliance tester. This is a self-signed cert that will expire about a week after SuperComputing. Please let me know if you have problems. Glenn
