Did the FTP server recently changed IP addresses ? (I ask because Java
caches IP addresses for a long time by default)
Do you have the possibility to check the actual trafic ? (with tcpdump
Also, telnet will not show the whole picture (it makes sure that the
initial connection to port 21 works but not that the subsequent
connections work - ftp is a protocol that uses 2 connections: one for
command and one for actual data transfer). Check with command line ftp
to make sure that it works.
mack, the FTP cerser did not change IP addresses. Don't know how to use tcpdump to check the traffic.
command line in telnet for listing a directory works fine.
This appears to be a CF8 issue. I can't get anyone to indicate that they can do directory listings with CFFTP on a remote server. I'd like to confirm this is an issue with my provider (FTP Today) versus a CF8 issue with this tag.
I've used CFFTP to list directory contents in the past and it worked
so I think the problem might be specific to your setup. My bet would
be on a passive vs active issue (a firewall rule that blocks the
incoming request for the active mode).
