Cannot connect to FTP server: "This security scheme is not implemented"

[tarest]

Yesterday I updated Total Commander to 9.51 64-bit version. Now I cannot connect to a FTP server.

By default I have this error:

Code: Select all

Using sChannel (Secur32.dll) for SSL/TLS connection.
Connect to: (2020-07-25 15:49:24)
hostname=ftp.cluster002.hosting.ovh.net
username=user123
startdir=/www/dir123

220-  ~~~ Welcome to OVH ~~~
220 This is a private system - No anonymous login

After creating the C:\Program Files\totalcmd\64 directory and copying libeay32.dll, ssleay32.dll, and openssl.exe to it as suggested on the https://www.ghisler.com/openssl/ page, I have the following error:

Code: Select all

I use Windows 10 Pro 1909 64-bit.
Before updating Total COmmander I was able to connect to this FTP server.

I can connect, if I untick the SSL/TLS checkbox in Total Commander FTP connection options. But is the connection secure then?

I can also connect using Cyberduck, recommended by OVH, when I select SFTP (SSH File Transfer Protocol), which sets:
URL: sftp://user123@ftp.cluster002.hosting.ovh.net
Server: ftp.cluster002.hosting.ovh.net
Port: 22

I have read that I should install SFTP plugin. Now I can connect to OVH FTP server, but when I try to compare FTP directory with local computer directory I obtain "?" for all files.

[tarest]

I unchecked the "by content" checkbox and now comparison of directories works flawlessly.

Conclusions: I have found two MAJOR UX problems.

The first major UX problem
In the FTP: connection details window, under the "SSL/TSL" checkbox there should be information that SFTP connection needs SFTP plugin with a link to it, for example: https://www.ghisler.ch/board/viewtopic.php?f=6&t=19994. I have been using Total Commander, its plugins, and FTP servers for about 20 years. But I was unaware that I need a plugin to obtain some security conections with FTP servers.

The second major UX problem
If the "by content" checkbox in the Synchronize directories window is checked by default, and if one of the directories is a FTP directory, then:
- the checkbox should be grayed out, and
- the checkbox should be treated as if it was unchecked.
If I connect to an FTP server without a plugin, then it works exactly as I described it. Unfortunately, if I use the SFTP plugin, then it doesn't work like this.

I spent about 6 hours to find the solution. If these 2 UX problems didn't exist, I would have done this in 10 minutes.

Update: I have reported the problems as a suggestion: Add info about SFTP to the "Connect to ftp server" dialog window, and as a bug: SFTP plugin > Synchronize directories: the "by content" checkbox should be grayed out

tarest,

In the FTP: connection details window, under the "SSL/TSL" checkbox there should be information that SFTP connection needs SFTP plugin

It does not, that checkbox refers to FTPS. Perhaps you are mixing up SFTP and FTPS?

Hacker,
I mean that in this window there should be information what one should do if he/she needs SFTP connection. I needed SFTP and I thought that I am supposed to try to configure it someway in this window, and if it will not work then my server is not supported by Total Commander.

Since today, I know the difference between FTPS, and SFTP, I do not mix them. I know that this checkbox is refers to FTPS. I mean that there should be also information about SFTP.

maybe some problem is in ssl cert
