FTP transfers hang in CS3 for Mac/10.5.4

Question

This is a topic that has been continually raised on this
forum, but never fully solved. I am using Dreamweaver CS3 on Mac OS
10.5.4.
When making a connection to my site's host, the client
connects properly, several files are transferred, then the
connection hangs as Dreamweaver continually tries to upload a file,
but is unsuccessful. This occurs while uploading different pages
with different files. The hang occurs after a few seconds of
activity.
For the record, I have tried both passive and non-passive
transfers, I am not operating behind a firewall, I have altered the
connection timeout settings from everything between 3 seconds to
120 seconds (60 is default). My site uses a fixed IP address and
the problem occurs both on my desktop (Mac Pro) and my laptop
(Macbook Pro) in different locations with different networks.
Background: Dreamweaver MX had this problem, CS2 fixed it,
CS3 has broken it again:
Dreamweaver
FTP problem
Fact: Using the exact same connection settings in Transmit,
the transfers have no problem. Dreamweaver CS2 does not have this
problem, either on Mac or PC.
It's time that Adobe got serious about fixing this. When a
thread exists with 80+ messages of complaint and there is no
resolution, there is a problem.
If anyone can shed light on this, it would be most
appreciated.

Answer 1

Ok, first off that thread was solved from what I read. The
original poster had an issue where they could only connect to their
server via IP address and not the domain name in 10.5.0 and 10.5.1.
They were told to fix the DNS and that the 10.5.2 update solved the
issue from Apple's end when it was released. This is now 10.5.4 so
this problem should be gone from the original poster because that
topic was started in October of last year.
Next, Mac does have a firewall by default like Windows. Look
in the System Preferences->Security->Firewall. Set it to
allow all incoming connections (basically off).
Next, have you gone through the FTP troubleshooting steps?
http://kb.adobe.com/selfservice/viewContent.do?externalId=tn_14834
If you have not gone through those at this point I would
highly recommend starting there. This will eliminate the cause a
bit more. Also on the Mac platform, I do not believe that I have
ever seen DW transfer successfully when Passive FTP is turned off
due to the Mac firewall, so I would recommend leaving that checked
while you test through the above KB article.
If you continue to have issues with the FTP after going
through those steps please post back with the progress.
And one other note. Adobe does not normally check these
forums. If you do require advanced support Adobe does have contact
information which can be found from the link at the top of these
forums (and every page of the site if I am not mistaken).
And lastly, as a suggestion I would recommend downloading the
CS4 beta (
http://labs.adobe.com/technologies/dreamweavercs4/
). All you need to run it past the 2-day limit is your CS3 serial
number. If something is broken in that version you would be more
likely to see it patched before the release as opposed to CS3 which
is on its way out. Also on that page you will find a link to the
CS4 forums which Adobe does check for bugs being that it is a beta
product.
