    Hi,
    Server: Windows server 2019

    ThinClient: DellWyse ThinOS 8.1.027

    I am facing an issue related to FTP connection with SSL (FTPS).

     

    So, what I did is at first I tried to connect through FTP and do RDP connection – it works.

     

    The next thing I’ve done is I generated a certificate using the IIS manager.

    I found it in Microsoft Management Console (MMS) and exported it at first to .pfx and then to .cer.

    I’ve uploaded the first one to ThinClient using FTP – I get information that the certificate is installed and when I chose “Require SSL” on IIS manager on Windows Server and restarts Thinclient it cannot access the system profile, so it seems it cannot connect through FTP.

    The same story is with second certificate.

     

    My wnos.ini file for .pfx certificate:

    Language=Us

    Screen=1 Resolution=DDC

     

    signOn=no

    autoLoad=1

    maxvncd=5

    vncpassword=ThinCli3nt

    vncprompt=0 accept=5

     

    AddCertificate=testcertificate.pfx\

    Password=123

     

    privilage = low

     

    include=$ip.ini

     

    My wnos.ini file for .cer

    Language=Us

    Screen=1 Resolution=DDC

     

    signOn=no

    autoLoad=1

    maxvncd=5

    vncpassword=ThinCli3nt

    vncprompt=0 accept=5

     

    AddCertificate=dercertificate.cer

     

    privilage = low

     

    include=$ip.ini

    FTPS is not supported.
    If you want to use SSL then go with https.

    Thanks a lot, I was fighting with that for 3 days already. It is good to know it is not possible.
    I will try with https.

    Do you know if SFTP (SSH) is possible?

    No, only ftp, http and https.

    Thank you, for your answers.

     

    I have another question.

    I’ve generated a certificate on my server, exported it, added it to Trusted Certificates in MMC, transfered to ThinClient.

    I couldn’t use option “SecurityPolicy”, so I upgraded my ThinOS and now it is possible.

    I’ve set this option to “warning” and here I see the issue.

    When I try to access system profile through https://servername…. ThinClient shows me a warning:

    “Failed to connect to the Connection Server[192.168.160.31]

    The server provided a certificate that is invalid.

    Click Continue to proceed(not recommended)

    Click Cancel to stop communication with the server

    See below for more details:

    -The certificate authority is invalid or incorrect.

    -The host name in the certificate is invalid or does not match.”

     

    My certificate host name matches the host name so it seems the certificate authority is invalid or incorrect.

    My question is: does it mean the connection will not be encrypted? If yes, what can I do without internet access to the thin client and without issuing for a certificate to official CA? The thinclient is just for internal use and internal network only.

    I’ve read what I did it is called “self-signed” certificate.

    Maybe the connection to file server through https will be encrypted when I click “Continue” on described warning, then I could just set SecurityPolicy to “low”.

    Important thing for me is that it will be secure connection through https.

     

    ThinOS version 8.6.412

    wnos.ini:

    Language=us

    Screen=1 Resolution=DDC

     

    SecurityPolicy=warning

     

    signOn=no

    autoLoad=1

    maxvncd=5

    vncpassword=testpassword

    vncprompt=0 accept=5

     

    privilege = low

     

    include=$ip.ini

    If everything is purely internal, stay with ftp. Using certificates correctly would require your own CA or official certificates.
    You can add
    SignOn=no EnableMessage=no
    to your wnos.ini to get rid of the “ftp unsecure” warning.
