>Description:
Safari 4.0.5 for Windows (7 in this case) doesn't list the directory contents on ftp.netbsd.org, probably a bug in ftpd (or in Safari, which needs to be worked around) as the mirrors work fine.

 Just a thought: Safari might be IPv6-stupid. Does it work if you browse
 to the IP-address instead of the DNS name?

 User error - I can reproduce it with ftp.netbsd.org, but it works with
 ftp.de.netbsd.org. Tracing the answers shows that ftp.netbsd.org opens
 a BINARY connection for /bin/ls, while ftp.de.netbsd.org uses a ASCII
 connection.

 Snips from the non-working trace:
