ipv6 & vista & winscp 4.04

I did some usability tests using IPv6 and Windows Vista. Here are the results.

Winscp version: 4.04
System: Windows Vista Enterprise 64-bit
Using a hostname that has only ipv6 address as "host".

--sftp / sftp--
gethostbyname: unknown error <OK> <Reconnect>
Fix needed: upgrade the putty code to at least 0.59.

--ftp--
Connection - Internet protocol version - Auto (it is gray but still selected!)
=> Connection failed. <OK> <Reconnect>
Note: the result is exactly the same with IPv4 setting.

Connection - Internet protocol version - IPv6
=> Works but ignores "passive" setting and always uses "active" connection.
It prints info about "PORT" command depending the status of passive flag but reality is different. This end result is that only user with admin rights (to allow traffic through the firewall) is able to use ipv6 ftp.

There exists ftp-ipv6 implementations that don't have this problem.

Unfortunately I really need a graphical sftp client. That is the only reason why I couldn't turn the local Windows Vista classroom into ipv6 only system. All the other programs that are needed (even the commercial ones) are ipv6 ready.

Unfortunatelly there's not an 0.59 version with Kerberos patch available yet.

--ftp--

Then it is "off".

I'll check that.

It just depends witch of the kerberos patches you are using.
There is one available for 0.60 at <invalid hyperlink removed by admin>
