Can you get a network trace e.g. with tcpdump of the connection?

I'm very sorry that this does not work for you. However, it does work for me, on both Linux and WinXP. On WinXP (running under VMWare) see the result of doing a clone in the attachment below. For Linux, I get:

I do not have any idea what might be going wrong for you. Please help us by sending debugging info. Add the --httptrace option to your clone command and see what comes back. Explain in detail your network configuration and setup. www.fossil-scm.org is now attempting to send a 20MB reply to the first clone query, whereas www2.fossil-scm.org limits the first reply to 5MB. Might this larger reply be causing problems for your firewall?

I just lowered the reply-size limit on www.fossil-scm.org from 20MB to 4MB. Please try again to clone from that site and report success or failure.

drh, now it works.

I'm using an ADSL router to connect to the Internet, I have no firewall, no AV software, no other active network interfaces. Also I have WinPCap installed but I don't think it can cause any problems.

As for [052de1d35b] I've sent you an email with --httptrace.
