Disable Implicit Port 990

I am using Filezilla server v0.9.60 beta. When I enabled FTP over TLS support (FTPS), port 990 was enabled automatically. We are using explicit security, not implicit. Is there any way to disable implicit port, i.e. 990?

Re: Failed to Connect from z/OS v2.1 to Filezilla Server

Maybe I targeted the wrong audience. Hi FileZilla Creators, Do you have a timeline on FileZilla server upgrade? The latest version was released on 8 Feb 2017. As not many companies are ready to upgrade their own OS to facilitate this change, may you consider retaining the option of 'TLS session resu...

Re: Failed to Connect from z/OS v2.1 to Filezilla Server

Hi Boco,

Do you have a timeline on FileZilla server upgrade? May you consider retaining the option of TLS session resume feature in future version and not make it a mandatory feature because not many companies are ready to upgrade their own OS to facilitate this change?

Re: Failed to Connect from z/OS v2.1 to Filezilla Server

It requires at least 1-year work which our whole company cannot afford right now.

Re: Failed to Connect from z/OS v2.1 to Filezilla Server

I am afraid to tell but z/OS ftp client support for resuming SSL sessions has been added with z/OS 2.2. We are using z/OS 2.1.

z/OS 2.1 only supports resume of SSL sessions for z/OS ftp server only. Could Filezilla ftp server be reconfigured to set resume of SSL sessions to be OPTIONAL?

Re: Failed to Connect from z/OS v2.1 to Filezilla Server

After updating host config, I tried again. I could successfully connect with Filezilla server in secured channel. But when I typed 'dir', it came out with the following error messages: 331 Password required for xxxxxx EZA1789I PASSWORD: EZA1701I >>> PASS 230 Logged on GU5349 ftpSetApplData: entered ...

Failed to Connect from z/OS v2.1 to Filezilla Server

I have already upgraded the Filezilla server to the latest version, i.e. 0.9.60.2. I have already configured z/OS host using AT-TLS.

Re: Control Cryptographic Protocols Used

I have just installed the latest version of FileZilla server to 0.9.60 beta. I performed testing on connecting to it with Filezilla client (latest version, 3.46.3). At first I generated a self-signed certificate with the following parameters: # openssl req -x509 -newkey rsa:4096 -keyout key.pem -out...

Re: Control Cryptographic Protocols Used

The version we are using is 0.9.44 beta. Is the latest version compliant to TLSv1.2? Are there any options to block SSLv2.0/3.0 and TLSv1.0/1.1?

Re: Control Cryptographic Protocols Used

When I searched on web, I found another ftp server product named 'Cerberus'. It is a paid product. It has the following configuration pages which determine SSL/TLS protocols (e.g. enablement/disablement of SSLv3.0/TLSv1.0/TLSv1.1/TLSv1.2) used and ssh security setup (ciphers, mac and active key exch...

Control Cryptographic Protocols Used

Recent audit scan reported that Filezilla server allows SSL connection while TLSv1.2 is not used. Is it the installed certificate issue or Filezilla server setting issue? What I want to achieve are as follows: 1. Disable SSL 2.0 and 3.0. Use TLS 1.1 or higher. 2. SSL certificate signed using weak ha...

Re: Generate Server Certificate using OpenSSL

Thank you very much. I have tried myself today. No need to change the label. No need to concatenate the files. Just do as what you have said: put the key file to 'Private Key File' field, and then put the certificate file to 'Certificate File' field. Restart the FTP server. That is. As I am testing ...

The content of the certificate file (one single file) generated by FileZilla is as follows: -----BEGIN...

Life of a SSL Certificate Generated by FileZilla Server

I am now using the FileZilla Server v0.9.41 beta. This version is able to establish a TLS connection between host and the ftp server. However, the life of a self-signed certificate that I can generated by 'SSL/TLS settings' under "FileZilla Server Options" is only one year. Would you mind doing me a...
