   Dear John

   Thank you very much for your email and for looking at
the problem.

   I started a transfer yesterday at about 8:00 pm, Paris local
time. About 10 files were transferred without problem. All are
transferred using "curl". At about 9:00 pm yesterday, I curl-ed
967615p but it vever finished: about 2/3 were only transferred
this morning at 7:00 am, though it kept continuing to transfer
(no interruption over the night). In order to understand what
could happen I then went to CADC interface and got this image
interactively, using wget. It worked well
, but transferred the .gz image (I usually transfer the .fz image). I
interrupted the wget after about 10 mn this morning since I saw
thre was no problmen with wget and the .gz image. THis is
why you saw a "failure" after 5-10 minutes, I guess? In any case, I
stopped the curl also and gave up. I will try again tomorrow and will
keep you informed on the transfer.

   Cheers and thanks again,

yannick
