GT 5.2.0 Release Notes


1. Introduction

The GT development team is pleased to make a new stable release of the Globus Toolkit available for download.

GT 5.2 is the culmination of more than a year of development effort to greatly enhance the ability to install, setup and update the GT client and service components. This has been achieved by providing binary native packages for the following platforms: Red Hat, Fedora, Debian, Ubuntu, Scientific Linux, and CentOS. We will maintain a Globus repository containing all packages. We have started the process to become package maintainers for various RPM and Debian repos and will be working to include the 5.2 Globus packages into these repos soon.

By following the Quickstart guide, you can now easily install and setup a full GT environment in minutes.

GT 5.2.0 includes the latest versions of all components: GRAM, GridFTP, MyProxy and GSISSH. This latest version of GRAM includes a number of scalability and reliability improvements found from working with Open Science Grid (OSG) that are not in the 5.0 series. GridFTP added support for the DCSC command, which allows the client to specify credentials used to secure the data channel connection. Globus Online utilizes this command for seamless data movement across multiple security domains.

GT 5.2 is protocol and client API compatible with GT 5.0 (e.g. 5.2 clients will work with GT 5.0 services, and visa versa.)

Highlights of this release include:

  • GridFTP

    • Support for DCSC command, which allows the client to specify credentials used to secure the data channel connection. Globus Online utilizes this command for seamless data movement across multiple security domains.
    • Server administrators may now restrict client access to a set of paths.
    • Data channel security for SSH GridFTP.
  • GRAM5

    • Better integration with Linux operating systems with native RPM and Debian packages.
    • Improved logging and integration with system log rotation tools.
    • Improved scalability and reliability.
  • MyProxy

    • Updated to MyProxy v5.4.
  • GSI-Enabled OpenSSH

    • Updated to gsissh v5.3.
