#1173 closed Bug report
SSL - directory listing unreliable

I see this very often when running FZ client against
the FZ server (implicit SSL). Not just the last
version (19) - it has always been like that.
Many times when I click on a directory it would wait
for several seconds just to came back with "Could not
retrieve directory listing". Refresh - and it does it
just fine. Locally or over the Internet.
This might not be a big issue when using a GUI client
and you're in front of the computer all the time, but
it's a real problem if it should be done from an
I'm currently evaluating IP*Works! SSL
and it seems to always have the problem, which
basically renders it unusable with FileZilla.
Also - don't know if it's related to the above, but
it also seems that the file transfer under SSL is not
very reliable either. Even with a (supposedly) good
connection, when I have multiple files in the queue I
get a lot (looks like) of transfer errors and
eventually some files won't get over, because the
number of errors reached the limit.
Again - not a huge deal if you're at the console all
the time, but quite unusable for "set it and forget
it" kind of mode...
Keep up the good work!

I am using 2.2.28 client and 0.9.19 server.
Any known issies with IP*Works! ?

Are you using any routers or firewalls? Improper
configuration of them can have a huge impact on FTP,
especially for SSL secured connections.

I see this behaviour with or without firewall. Probably
more often with a firewall, but definitely also on the
local network (it does go through a router of course, but
there's nothing fancy about it) and even on the local
machine connecting to the loop-back adapter (though far
I do have my FZ client set to passive mode and have
limited the port range.
That said I'm leaning to believe that this is a server,
not a client problem. I tried it with SecureFTP client
(http://www.glub.com/products/secureftp/) against the FZ
server and it seems to exhibit the same problems.
Also - I couldn't make a similar setup using different
server software (Serv-U ftp server) to fail even once. I
had no control there though and it was set for explicit
SSL (if that should make any difference).

This problem is most likely caused by improper router or firewall
configuration. Please read the FAQ for details.

I found a glitch on my firewall/network setup.
Fixing it greatly reduced the occurrences of the above
issue and I would say that the remaining occurrences
(again - negligible number) are within the expected
