Mac clients not able to connect to IIS6 FTP


Mac clients not able to connect to IIS6 FTP Vassili
1/9/2006 2:47:02 PM
iis ftp: A few weeks ago installed a brand new Windows 2003 server. It's behind a
firewall, port 21 is forwarded to it. Anonymous access is disabled, users
have to authenticate. PC users have no problems. No one using a mac is able
to connect, however, it appears as if they authenticate successfully, but
then say that they are unable to retrieve the list of contents. Is there
anything special I have to do to the IIS to make it accessible to macs, or

Just looked at the logs. If there is anything I guess I can't interpret it.

Here is what it logged for me

20:49:20 <MY IP> [51]USER vip 331 0
20:49:20 <MY IP> [51]PASS - 230 0
20:49:43 <MY IP> [52]USER vip 331 0
20:49:43 <MY IP> [52]PASS - 230 0
20:50:04 <MY IP> [52]CWD /F060106A.EST 550 2
20:50:04 <MY IP> [52]CWD / 250 0
20:50:06 <MY IP> [52]created /F060106A.EST 226 0
20:50:14 <MY IP> [52]DELE F060106A.EST 250 0

It let me connect, upload and then delete a file

Here is what it keeps logging for mac clients

20:39:49 <CLIENT IP> [44]USER vip 331 0
20:39:49 <CLIENT IP> [44]PASS - 230 0
20:39:49 <CLIENT IP> [44]CWD / 250 0
20:40:59 <CLIENT IP> [45]USER vip 331 0
20:40:59 <CLIENT IP> [45]PASS - 230 0
20:40:59 <CLIENT IP> [45]CWD / 250 0

They used the same username and password that I did

I have a little (very little) experience with Macs and Win2k3.

We never got any successful session with any Mac running OS9 or older.

OSX appears to work better. Users use Safari and something called
Jaguar. I believe IE6 works OK too.

AOL users are just out or luck no matter what they use.

If someone knows anything different please let us know the secret.

Shouldn't be. Did you check the FTP logs to see what's going on?

I think I found what the problem is, now if I can only find out how to fix it.

Macs can connect to that site over the LAN fine. They can also hit an
internet IIS FTP server that is not behind a firewall. But they cannot
connect to one that is behind a firewall. That leads me to believe that macs

Assuming it's not a nonstandard port, try 20 and 21.

What are they using for an ftp client? I would try the command line and
a freeware gui client or two to see if you have consistent results. If

From your other posting, it doesn't indicate any failure in the log file.
It looks like ftp mode issue. active mode uses 21 and 20. 21 inbound whereas
20 outbound from the host.
passive mode uses different port range. default 21, 1024-5000. refer
Information About the IIS File Transmission Protocol (FTP) Service

so in your case, can you configure your ftp client to test connect via
active mode first.....

Sorry about the delay. Tried port 20 (never knew before it even existed), no
difference whatsoever. I have given up on this, we will either move ftp site
to a mac server, or to an external provider, in both cases it will be out of
my realm at that point. It seems that macs still need more ports then that,
since internally they have no problems at all. But I don't know anything
about them, nor was able to find a mac expert. Thank you everybody for your

We had the same problem.
The answer was to download a free Mac FTP program that let us change the
mode between PASV and PORT. I can't remember which one worked off hand but
one did. You may be able to change the mode in the default MAC client but I
don't know how.
