VDT 1.3.3 Release
We are pleased to announce the release of VDT 1.3.3.
- The DRM web services interface (SRM) is installed and
configured. Users should note that it runs on ports 8081 and 8444
instead of the usual 8080 and 8443.
- The Globus log rotation cron job will no longer complain about compressoptions.
- EDG-MakeGridmap can now build grid-mapfiles from the VOMS server included with VDT 1.3.3.
- You no longer need to restart Apache and Tomcat after installing VOMS or jClarens.
- jClarens no longer creates extra directories in /home.
- The VDT will now install on an AFS file system.
- The configure_voms script can now be run after the installation to set up additional VOs.
- The Globus GRIS works properly again. This corrects serious bugs in VDT 1.3.1 and 1.3.2.
- Logrotate 3.7
- Apache 2.0.53
- jClarens Discovery Service 0.5.3
- PPDG Cert Scripts 1.5
- Fault Tolerant Shell 2.0.11
- UberFTTP 1.11
- Java 1.4.2_07
- Condor 6.7.6
- DRM 1.2.6a
- VOMS 1.4.0
- Condor 6.7.6 includes the Stork data placement
- The Globus Simple CA is now included, but is not set up by
default. It is officially part of the Globus distribution, so we
don't separately version it.
- The Globus GridFTP server from Globus 3.9.5 is now available as
an optional install (the package is named
Globus-New-GridFTP-Server). It will run on a different port, 2812, than the
default GridFTP server. Bill Allcock from the Globus Alliance says:
Why use the new GridFTP server? From a protocol level, the servers are
completely identical. Old clients can talk to new servers, new clients can
talk to old servers, you can third party transfer between a new server and
an old server, etc, so it is NOT mandatory that you upgrade. The real
reasons for using the new server are more subtle. First, this code base has
been subjected to a much higher level of testing than the previous server.
We have successfully handled 1800 clients on a single host, we have achieved
90% utilization on a 30 Gbs link, we have had single file transfers that ran
for a month. Second, bugs in the new server are our top priority, while
bugs in the old server are very low priority. Third, documentation on the
new server is significantly improved. Finally, the new server gives you
additional flexibility. We are working on custom Data Storage Interfaces
(DSI) to NeST, SRB, and HPSS. If you want to add custom functionality,
there are clean interfaces in all the right places, so it should be
relatively easy to do, where it is completely impractical with the old

- Nest version 0.9.7pre1 (the package is named Nest), from the Condor Project is now
available as an optional install. It relies on the new Globus
GridFTP server, and it modifies the install so that all incoming
GridFTP requests to the new server will use Nest for all interaction
with the disk.

- In VDT 1.2.0 we changed the xinetd configuration from running
the Globus Gatekeeper and GridFTP servers directly to calling a
small wrapper script. If you use TCP wrappers and are upgrading the
VDT from a pre-1.2 release you will need to change the appropriate
entries in /etc/hosts.allow and /etc/hosts.deny. More information
can be found in our TCP wrappers
- All web services (Apache, Tomcat and DRM) now run as the daemon
user. If you previously had an http service cert owned by nobody
you'll need to chown it to daemon.
- Discovered that the VOMS server does not work on Debian Linux.
We're working with the developers to fix this for a future VDT
release. For now VOMS will not be included with an install on
- Discovered that the DRM does not work on Debian Linux. The VDT
1.3.3 install on Debian will not include DRM.
