* Summary:
	- The CoG's file listing GridFTP operations don't work with GridFTP 2.0 servers in GT 4.
	- PWD is flaky (sometimes works, sometimes not).

* GridFTP Installations
	- palermo.ucs.indiana.edu runs GridFTP v 1.17 from NMI R5 (~ 1 year old).
	- danube.ucs.indiana.edu runs GridFTP v 2.0 from the GT4 release (from globus.org).
	- gf1.ucs.indiana.edu runs GridFTP v 2.0 (the same) from the NMI R7 release.

* Set up: 
	- I run all servers in the standard way, as root, started by xinet.d.  
	- I checked installations using the globus-url-copy tool in various combinations
	  (gf1 connect to danube, danube to palermo, danube to gf1).  After lots of fun with
	  certificates and signing policies, it all works.
	- Note of course this does not let me verify the list operation that causes problems.

* Here is my cog-kit set up:
	- I use Mike's maven stuff to download all cog-jars.
	- After unpacking, I run

		maven ogceDeploy:ogceDeploy -Dtomcat.home=$HOME/GridFTPTest/test-shared-libs

	- I set the classpath to point to the bazillion jars in the shared/lib that gets created.
	- I then compile the demo FileOperations.java program from the CoGKit website 
	  (I downloaded it directly from the website).

* Sanity check:
	- I run several commands successfully against the old GridFTP 1.17 server on palermo.
	- OK, rmdir doesn't work but I may just be using it incorrectly.

* Now for GridFTP on gf1.  The following work OK.
	- cd <directory> works (verified with mkdir)
	- mkdir
	- rmdir (actually doesn't work but doesn't report errors either).
	- isDirectory
	- exists
	- rename
	- putfile 
	- getfile
		 

* Below are the commands that cause problems.  These are the same for both the NMI R7 server
and the GT4 version (not unexpected since they are identical versions).

Problem: PWD.  Actually, this always seems to fail when used immediately
after another client command (ls, cd, etc), but then works the second time.
