Globus Security Update

The VDT team has been working hard on distributing the Globus security update. It's been slow for a few reasons:

That said, we're getting very close. By the end of today (Thursday, August 17th) we think we will have VDT 1.3.9 and 1.3.10 ready to be tested in our nightly test suite, and 1.3.11 should follow no later than tomorrow. We hope to release early next week, assuming no more big problems arise.

The update will be applied by fetching an extra package into your VDT installation. This package can be removed with a Pacman command, and it will "rollback" to the way it was without the security update. This will allow people to restore their installation if there is a failure due to the update. OSG will include this update in their packages

Our testing includes using the Linux strace command by hand to ensure that we are hitting the new code that fixes the problem, and using our nightly test framework to run the code on all platforms.

Condor question from Alan Sill (via Rob Quick)

Alan Sill asked (via a GOC ticket) what it means that the VDT-Client asks about enabling Condor to run automatically. If you install as root, the VDT will ask this question. It means that Condor will start up automatically. If you use Condor for it's grid capabilities (Condor-G) it will start up on that computer, and all users on that machine can submit jobs. It's the same Condor you get for a full batch system install, but it's only on one computer.

GridIFTP problem from Wayne

Wayne Betts reports that GridFTP works fine for me, but not for the probe used by GridCat since he updated to OSG 0.4.0. It sounded like a firewall failure, and Wayne was checking that he used GLOBUS_TCP_PORT_RANGE properly.

TclGlobus, 64-bit

TclGlobus folks report that they are continuing to work on TclGlobus 1.4.0, which will support 64-bit platforms. They're testing on three platforms to make sure that they iron out all problems (Solaris 10/Sparc, Solaris 10/Operton, Fedora Core 4/Opteron). They're close, but tracking down some possible race conditions due to having multiple cores.

They're still working on the new license

Alain gave them a heads up that he'll need help getting their tests to run in the VDT nightly test suite.
