Re: Disable TLS 1.0 & 1.1

OK, well editing the default Priority string in libfilezilla-10.dll is not effective, as the files digital signatures are damaged (tried it). How about adding this TLS 1.2++ only as an option, or as a manual override setting we put in the .xml file? Or maybe a way to make the debug Priority string b...

Re: Disable TLS 1.0 & 1.1

Hi, Yes, the problem turned out to be something else - virtual host names and internal binding errors at the server. Sorry for the miss direction. I know you have done many laps trying to address all the issues in TLS across the board. I did some further digging with Wireshark. I see that FZ client ...

Re: Disable TLS 1.0 & 1.1

Hi, How do we apply the above fix to the client? My Server with IIS is configured to only use TLS 1.2 (or more). But the FZ client initial attempts at connecting (implicit FTP over TLS) is done at the TLS 1.0 level (Client hello packet). This is met with a hard fail from the server pushing an immedi...

GnuTLS error -110 on IIS

I updated the server cert as it had expired. The new cert immediately made the the error GnuTLS error -110 The TLS connection was non-properly terminated. I figured it out, so I should share the solution. The The TLS connection was non-properly terminated. is the second fault and a consequence of th...

Re: Can't connect to Windows Server 2012 (IIS 8) FTP when us

Not ending the session with a closure alert is not only a security vulnerability, there are servers which require the connection to be properly closed. Agreed. I think the best solution is to give your users a choice. Don't force your users to work with TLS 1.1 or 1.2. These protocols seem not so w...

Re: Can't connect to Windows Server 2012 (IIS 8) FTP when us

The client then deems this as a failure and deletes the file. FileZilla never deletes partial transfers. Its not a partial transfer, it was a complete transfer. But because the server / client was missing some required / needed handshake component at the end of the transfer, it was then deemed a de...

Re: Can't connect to Windows Server 2012 (IIS 8) FTP when us

I'm thinking of enabling it in the next version. Probably be out this month still. Its nice to see you looking into this... But I think your only half way there. Did you try a file send and receive? I think you will find the old problem of 3.5.3 where the server closes the socket abruptly, because ...

Re: Can't connect to Windows Server 2012 (IIS 8) FTP when us

I have the answer, because I HAVE gone to the trouble of identifying exactly what makes it all fall apart. Your analysis coupled with careful study of the TLS specifications is what I base my results on. So you have never taken anyone up on the offer to test against a real server, or to run differe...

Re: Can't connect to Windows Server 2012 (IIS 8) FTP when us

I have listened to all your concerns and found out that the problem is with the server. I gave you the correct solution, which is to fix the server. What else can I do? Oh really? I don't believe you have looked at this issue in depth at all. I think you have just decided on the (its broken) excuse...

Re: Can't connect to Windows Server 2012 (IIS 8) FTP when us

I would have thought that you were a better programmer than that. I'm sure a halfway decent programmer could make it work with IIS 8 and not break compatibility with other servers, if they wanted to. You are correct. I managed to make it all work on all the servers I have access to - old and new - ...

botg: I see your back on your soap box, putting your fantasy views, and political agenda ahead of the users and the FTP products. At least you are being a little more honest with us now. 1/ Server admins are not going to change server types or ftp daemons - just to suit you - just to get a "fil...

Re: Can't connect to Windows Server 2012 (IIS 8) FTP when us

I fixed it. I hacked your binary and replaced the priorities string value, used the gnutls_priority_set() function. I corrected the error in the config. Now I have a TLS 1.2 connection to an MS FTP server, and using the highest ciphers, and appropriate extension conditions. All of it now PCI complia...

Re: Can't connect to Windows Server 2012 (IIS 8) FTP when us

Read several of my previous replies and this time contemplate on what's written. Here is further evidence to show you have a bug. If we connect Filezilla client to a Server, on port 990, which is implicit SSL, then guess what.... the client starts with a TLS v1.2 value in both inner and outer wrapp...

Re: Can't connect to Windows Server 2012 (IIS 8) FTP when us

You keep telling your self those lies... Your wishful thinking is not going to save you. Filezilla does NOT send a compliant message. Filezilla breaks the rules. Garbage out - garbage in. Your filezilla gets rejected because it sends a garbled message. Your the one with the broken software - your fi...

Re: Can't connect to Windows Server 2012 (IIS 8) FTP when us

The facts are in appendix E, it clearly says that using a record layer version of 3,XX is allowed and that TLS 1.2 compliant servers MUST be prepared to handle this. Except the fault lies in the Client. The client is sending defective and invalid connection requests. Worse thing is, you know the cl...
