I have been 'slowly' downloading the first ISO using 'curl' as per the instructions. After nearly 90mins I get the following message. curl: (18) transfer closed with 638458876 bytes remaining to read No problem ... I'll just restart, however I now get this message... curl: (33) HTTP server doesn't seem to support byte ranges. Cannot resume. The RHN website suggests that I should be able to restart!? Any ideas?
