Hope this is not too far off-topic.
I've failed to downlaod the DVD iso twice, using Firefox.
Once from Duke when I didn't leave enough room in /tmp (argh)
and cnlab-switch.ch timed out las night.
I've tried wget several times to the cnlab-switch ftp site.
Even with --ignore-length (appropriate for http I know)
it is fetching a 84,785,152 byte long file.
