Note: This version of the VDT (1.10.1) is supported, but is not our latest stable release. The current stable release is 2.0.0.

Using Lotman in the VDT 1.10.1

Lotman is an extension to the Globus GridFTP server that allows you to control how much data users can store, so that users do not exceed limits that you set.

Lotman was added in the VDT 1.10.1 release, and in its initial release was barely tested by the VDT team. Consider it to be beta quality until further notice. that said, we encourage you to try it out.

Lotman requires GridFTP from Globus 4.1.3, but this version of the VDT already has Globus 4.0.7, so we install this new GridFTP in a separate GLOBUS_LOCATION, in $VDT_LOCATION/globus-new/

To install Lotman and the new GridFTP server, run:

pacman -get http://vdt.cs.wisc.edu/vdt_1101_cache:Lotman

To enable the new GridFTP server, without Lotman:

> cd $VDT_LOCATION
> . setup.sh
> vdt/setup/configure_gridftp --new-gridftp --server y
> vdt-control --on gsiftp-new

Note that it will run on an alternate port, -2812, unless you specify an alternate port:

> vdt/setup/configure_gridftp --new-gridftp --port 2811 --server y

Note that port 2811 is the standard port for GridFTP. The VDT does not verify that you run this new GridFTP server on a separate port from the old GridFTP server, but that is up to you. If you want to run just the new GridFTP server, you could do this:

> vdt/setup/configure_gridftp  --server n
> vdt/setup/configure_gridftp --new-gridftp --port 2811 --server y

If you want to enable Lotman, pass the --use-lotman flag. You can use it combination with the other flags described above. For example:

> vdt/setup/configure_gridftp --new-gridftp --use-lotman --server y
