Hi Pete,
GridFTP server on EC2 machine enters Passive Mode and sends to another GridFTP
server information about IP address and port number the server listens on to
establish a data channel.

The address is from an IPv4 address range for private networks not routed in
internet. You need to run globus-gridftp-server with the option -data-interface
<public_ip_address> where the 'public_ip_address' is a public address assigned
to your EC2 machine.

Lukasz

Hi there,
I've seen the zero KB file issue when there are firewall issues.
Specifically, it looks like you have traffic allow one direction but
not the other.
It may be working between EC2 instances due to them being in the same
zone, and traffic is handled differently than for outside requests.
Did you add all the ports explicitly in your EC2 Security Groups
inbound connections configuration? I think this is most likely the
issue.
You might also install iptraf on the Ubuntu side and run that while
connecting from both the other EC2 instance and from OSX to further
identify if connections are being made.

Hello,
I built version 5.0.4 on Ubuntu (Amazon EC2) and ran gridftp in
anonymous mode as a test as follows:
globus-gridftp-server -aa -p5000
I then tried to retrieve files from another Ubuntu EC2 instance using
globus-url-copy and that worked fine.
I then did the same thing on my Macbook (OSX Lion), and ran the
gridftp server in the same way, and was able to get files by
referencing localhost. However, when I try to retrieve files from the
Ubuntu EC2 server to my Macbook, nothing comes across. The file itself
gets created but globus-url-copy hangs and the file size always stays
at 0. The same thing happens if I try to upload a file to the EC2
server from my Macbook. Incidentally, I can retrieve directory
listings via the -list modifier. I turned off my macbook's firewall as
a test and can see that the connection to port 5000 has been
established.
Below is a snaphost of the output of globus-url-copy from my macbook
with -dbg set. It just hangs at the RETR command.
Any thoughts to debug further would be appreciated.

Raed
