Hi Saurabh,
The UDT driver isn't currently available as an rpm, it must be built
from the source installer. The error is incorrect and is actually due
to the driver not being found.

Hi,
We have configured and installed a Linux CentOS 6.4 server and installed
GridFTP 5.2.4 RPM's available from the Globus repository. A GridFTP
client is installed on another Linux server on the local subnet. The
authentication and data transfer between the client and server is
successful, but there is no acceleration in speed through gridFTP .
1)When transferring over the TCP protocol, the speed with normal ftp and
GridFTP are same in spite of using options like the TCP buffer stream
and parallel streams and other switches such as "-fast". We are not able
to understand why we don't achieve a speed-up in transfer speeds using
GridFTP.
2)We configured GridFTP to transfer data over UDT by (i) running the
GridFTP server from xinetd, added '-dc-whitelist udt,gsi,tcp' to
'server_args' in /etc/xinetd.d/gridftp. We also threaded the GridFTP
server by adding the following variable to the /etc/gridftp.conf file
<file:///tmp/notes749539/%C2%A0>'$GLOBUS_THREAD_MODEL=pthread'
The data transfer was then performed using the following command :
globus-url-copy -vb -r -udt -cd
gsiftp://192.168.12.10:2811/valid/path/to/data/ _file:///tmp/data/_
<file:///tmp/griddata/>
However, this returned the following error:
+++++++++++++
error: globus_ftp_client: the server responded with an error
500 500-Command failed :
globus_i_gfs_data.c:globus_i_gfs_data_request_command:3981:
500-Setting data channel driver stack failed.
500-globus_xio_attr.c:globus_xio_driver_list_from_string:329:
500-Bad parameter, udt driver not whitelisted
500 End.
+++++++++++++
Is there a configuration that we missed for using UDT?
