Bug Description

Markus reported problems with ncftpd and LSIs. I could repeat his problem as follows:

mkomu@bling:~$ wget ftp://1.0.0.2/welcome.msg
--2011-09-13 14:32:46-- ftp://1.0.0.2/welcome.msg
           => `welcome.msg'
Connecting to 1.0.0.2:21... connected.
Logging in as anonymous ... Logged in!
==> SYST ... done. ==> PWD ... done.
==> TYPE I ... done. ==> CWD not needed.
==> SIZE welcome.msg ... 170
==> PASV ...
Cannot parse PASV response.
==> PORT ...
Invalid PORT.
Retrying.

According to Markus, the bug is independent of passive vs. active mode. Apparently the "entering passive mode" message is broken and the port field contains some invalid data.

HIT-based transfer (and other stuff, e.g. http and ssh) works though. So this problem could be related to the referral stuff in FTP as the protocol exchanges IP-address information over the wire. In my case, the LSIs matched on both ends so mismatching LSIs are not the issue here.
