downloading long files

[Michele Simionato]

I have a connection which is not 100% rock solid, so if I try
to download a large file (i.e. a Linux ISO image) chances are
that the connection will break. Is there a way to check periodically
if the connection is open, reopen it if needed, and continue the
download without restarting from the beginning?

yes, use wget http://www.gnu.org/directory/wget.html
or are you looking for a pure python solution?

What has this to do with python?

Anyway I'm assuming linux since you mentioned it,
so use wget or even better:
rsync -P rsync://rsync.server.com/path/to/file file

A pure Python solution would be preferable, indeed.

If I remember rightly, there is python code for a resumable HTTP
downloader in the Python Cookbook. I don't think it would take much
work for it to handle FTP, too.
