Here is what I get:

$ wget -S -v -d ftp://ftp.cs.huji.ac.il/
DEBUG output created by Wget 1.10.2 on linux-gnu.

Using `.listing' as listing tmp file.
--20:56:56--  ftp://ftp.cs.huji.ac.il/
           => `.listing'

So I suspect that for some reason the FTP server closes the connection
and that's what the frp client reports as "Error in server response".
A sniffer output (as Ariel suggested with Wireshark) and maybe an
strace on the client might help understand what's actually is going
on.
