I'll leave the rsync question to the experts - worked for me, but I don't know why it worked for me (linux/ubuntu laptop, not networked) and not for you .
 
About the filenames: You can download a file listing to text.txt by
 
.../galaxy-dist$ rsync -avzP rsync://datacache.g2.bx.psu.edu/indexes > text.txt
 
and then choose which one you want. File size warning: this is something like 200 MB. Trying to download the much shorter list for phiX might be a quick way to check whether it works:
 
.../galaxy-dist$ rsync -avzP rsync://datacache.g2.bx.psu.edu/indexes/phiX > phiXlist.txt

Subject: [galaxy-dev] Local installation: Questions about using rsync to retrieve a genome

Hi,

1) I'd like to fetch the genome of H. salinarum NRC-1 on my local installation. Following your advice (http://wiki.galaxyproject.org/Admin/Data%20Integration
I wanted to use rsync. To begin with I tried the example in the above url, even though that's not the genome I'm interested in:
  
 rsync -avzP rsync://datacache.g2.bx.psu.edu/indexes/phiX .
 
I didn't get any response. My questions are:
1) Is it because the ftp site was not on ? Or could it be a firewall problem? Can the site be accessed in a different way that I can try?
2)Where can I find the file name where the H. salinarum NRC-1 genome resides on the server?

 Thanks for your help.

                                  Boaz
