We are hosting a ws-ftp server (Ipswitch) and recently we upgraded from version 7.7.0 to 8.5. After the upgrade we got calls from clients complaining they can't connect anymore.

These clients are using WinSCP 5.5.1. I tested it myself with version 5.1.3 and have no issues so I tried WinSCP 5.5.1 and I cannot login anymore. The error I see on the server is Invalid Public Key, but the authentication method is username and password.

Last thing I did was try to use the most recent version of WinSCP 5.11.2 and there the issue has gone again, I can login.

Any idea what's going on?

So use the latest version. It's the right thing to do in any case.

If you want us to investigate this any further, we need to see WinSCP log files form all three versions.

I could not agree more, next challenge is to tell this to our clients Wink

I think we can stop looking, this is what I got back from the guys that bring you ws-ftp:

I've been doing some testing against my WS_FTP Server 8.5 with various versions of WinSCP.

I've found that any version between 5.5.1 and 5.7.4 will fail to connect to our server. Looking through my verbose server logs I can see that all those versions are attempting to use the Diffie-Hellman-group-exchange-sha256 key exchange algorithm.

From WinSCP 5.7.5 upwards it is using the same algorithm but will allow the connection to go through and be successful. With this particular version they implemented the following.

Supporting the RFC 4419 revision to Diffie-Hellman group exchange.

This was to fix an issue connecting to OpenSSH 6.9 servers using the same algorithm as described in the link below.

https://winscp.net/forum/viewtopic.php?t=15626

The reason this never affected them before was that we only added Diffie-Hellman-group-exchange-sha256 into WS_FTP Server 8.5, it was never present in 7.7. However our implementation of it as it is very recent will adhere to RFC 4419.

in addition the reason why your original version of WinSCP 5.1.3 was working is that it doesn't support Diffie-Hellman-group-exchange-sha256. In testing with that version against my server it was using Diffie-Hellman-group14-sha1.

So in short this is a client side issue which to address they will need to upgrade to at least WinSCP version 5.7.5.

So use the latest version. It's the right thing to do in any case.

If you want us to investigate this any further, we need to see WinSCP log files form all three versions.


I could not agree more, next challenge is to tell this to our clients Wink
