Hi YangXin,

That's great news!  As soon as we have accounts in place at all the transfer 
sites, 
hopefully we could complete testing in a few weeks.  Please allow access from 
the
system zero.unidata.ucar.edu (128.117.140.56).  

Thanks for the bandwidth information and the account access!

Best Regards,

mike
