FTPS does not work

Reported by: Dmitry Dzevel Owned by:
Priority: high Component: FileZilla Server
Keywords: FTPS SSL Cc:
Component version: Operating system type: Windows
Operating system version: Windows 2003

Description (last modified by Tim Kosse)

Configured Filezilla server v. 0.9.36 for FTPES and FTPS.

FTPES works OK: at first login server send client certificate, after accepting, it connects to the site.
FTPS does not work: same client, same server. Server does not sends certificate to client. Up on connection, I receive error: "500 Syntax error, command unrecognized".

I thought it was due to firewall so installed server and client on the same machine to remove and dependencies on firewall or routers: same result. I tested this with server version 0.9.34, 0.9.35.

CLient is Filezilla 3.3.4.1 but i had same results with SmartFTP client.

Incorrect configuration. You need to use the SSL port for implicit FTP over TLS, only explicit FTP over TLS can share the same port as regular FTP.

Replying to codesquid:

Incorrect configuration. You need to use the SSL port for implicit FTP over TLS, only explicit FTP over TLS can share the same port as regular FTP.

??!!

I'm using port 990 for implicit FTPS. Logs I've attached to the ticket shown that
FTPES (SSL over port 21) is working OK, but FTPS - SSL over port 990 -
does not. I had sent output from from both: FTPES and FTPS - please doublecheck. Why else i mentioned FTPES: it uses same certificate so no issue with it.

I've attached server config. Can you please check what if anything in the configuration i should changed to fix FTPS issue.

FTPS does not work when i use Filezilla FTP server. For test I had
installed Cerberus FTP server on the same machine, configured same
way: ports 21 and 990, FTPS and FTPES only, allow connection only via SSL, etc. Cerberus FTP works with no problem.

You should not close this ticket. I need to fix this problem ASAP.

Any updates on this?

comment:5 Changed 9 years ago by putte

Your configuration file contains these lines:

<Item name="Serverports" type="string">21 22 990</Item>
...
<Item name="Implicit SSL ports" type="string">991</Item>

So have you tried connecting to port 991? If it works, try setting "Serverports" to 21 and "Implicit SSL ports" to 990.

From the log it looks like you have configured FileZilla to expect an unencrypted control connection on port 990, which obviously doesn't work.

I guess, Probably this error happens because you have checked "Allow implicit SSL/TLS" (or "Disallow plain unencrypted FTP") box.
Thus, during first server/client connection the server should send through unencrypted stream the digital certificate and client should accept the one. Disallowing plain unencrypted FTP (or allowing impicit SSL/TLS) you forbid during the first send the digital certificate and therefore you got syntax error because server expects totally encrypted commands and when server gets unencrypted command, the server sees it as encrypted.
It's just my opinion. Try to remove implicit connection during first run and let accept server's certificate by FTP client and then enable again and PROFIT.

Guess the original poster does not have the problem anymore, as there is no reply.
