VDT 1.6.1e Released

The VDT team released a small update this week to fix a security flaw in GSI OpenSSH and provide an update for the Generic Information Provider (GIP). Most VDT users are not using GSI OpenSSH, but if you are, it is recommended that you upgrade. The GIP was upgraded to fix problems that caused incompatibilities with WLCG and problems with collection of accurate VO information from PBS. The VDT team recommends that all OSG users upgrade.

Certificate Update Script

Doug Olson announced that he is working on a script to make it easier for sites to update certificates in the grid-admin. This new utility will make multiple requests using only a single SSL connection. It uses Python and the M2Crypto toolkit. He asked whether the VDT will be able to support this configuration. Alain Roy commented that he will need to investigate what it takes to include Python modules in the VDT. He believes that it is slightly more complex than Perl because we will need to test on multiple versions of Python.

Another user asked whether a VDT installation uses the Python provided by the operating system. Alain remarked that this depends on whether the system's installed version of Python is new enough. For example, if one installs the Gratia-SGE-Probe package, the VDT will check whether the system has at least Python 2.3, and it install it if not.
