They claim that they have no firewall.

Are you sure this isn't a firewall issue on their end?

            We are not using SSL.
         
            We already use 'fixup'.  The directory listing works for our
other customers who use the server, just not this particular one.

        Are you using FTP w/SSL?  If so, you basically have no choice
but to use passive mode.  If you can't, you probably will never get FTP
w/ SSL to work.
         
        If you're NOT using FTP w/ SSL and it's just basic FTP, has your
firewall been setup to "fixup" the FTP protocol?  Since you're using NAT
your firewall has to recognize the FTP traffic and re-write not just the
packet headers (Source & Destination addresses) but also the internal
data-frames of the FTP packets.  FTP is an "old school" protocol that
embeds source & destination addresses in the datagram.  Probably a bad
design decision back then, but in 1960-whatever no one envisioned NAT
so.... it only became a problem many years later.
        

        Make sure your firewall is doing "fixup" (cisco terminology,
probably called something else on other products) for FTP.

        Good luck.

            Our firewall rules block passive mode, so that is not an
option.
         
            I am unable to access the URL provided (cannot find the
server or DNS error).  We use 192.168.. for our internal network.  Isn't
this a non-routable address?

        Doug,

         

          This is probably the most common problem in FTP, can not
establish data channel.   In this case, the server can not connect to
the client on the ip, port specified.   Most of the time this is due to
firewalls blocking the new connections. I would try passive mode.

         

          For more info look at this page:
http://192.168.5.164/data%20channel.htm

        Customer complains that directory listing doesn't work, so can
only do a CD blindly.  I have pasted his log below, which shows no
response to LIST.  I'm stumped as to why.  He is using PRO 8 and
connecting to SERVER 5.  None of my other customers have this problem
and I can't reproduce it using PRO 9.  Anybody have any ideas?
