Hi.
Oddly enough, I took out the code where you pass the login and password, in
my FTPSClient (i.e. //client.login("test","test");) and got connected.
However, whenever I did a command listing, it will just hang like before.
so anything to do like
//client.cwd("temp");
//client.list();
will hang..
btw. I took the latest FTPSClient code from Apache too.
