Description Valdis Kletnieks 2004-07-09 17:18:10 UTC

Description of problem:
ncftp fails and sends a FIN when it talks to the data socket.

Version-Release number of selected component (if applicable):
3.1.7-4

How reproducible:
Connect to an FTP server, and issue 'dir' command in non-passive mode

Steps to Reproduce:
1.
2.
3.
  
Actual results:


Expected results:


Additional info:
Ethereal indicates that the PORT command is sent, the 3-packet
handshake takes place, and after the first data packet (containing
a '150 Here comes the directory listing.'), the client end sends
a FIN packet.

Backing off to 3.1.7-2 works.

Ethereal capture is available if needed.

Looks like the ipv6 patch is doing something strange here.

Comment 2 Valdis Kletnieks 2004-07-09 18:28:13 UTC

The laptop exhibiting the problem has IPv6 enabled,
but ethereal shows the connection as IPv4.  Could it be a problem
with handling a ::ffff: encapsulated address?

Comment 3 Karsten Hopp 2004-08-09 10:24:12 UTC

I've notified the uptream maintainers of the ipv6 patch of this 
problem and disabled the patch for now.

Comment 4 Karsten Hopp 2004-08-19 12:41:22 UTC

waiting for a new upstream ipv6 patch
