Topic "Connectivity issue with WinSCP to Unix server."

We have WinSCP 5.5.3 installed in our operations server and we use it in order to connect to our Unix servers. We have three Unix servers and we are able to connect to two of them but are having difficulty connecting to the third one. I get this error during the sign process.

Error skipping startup message. Your shell is probably incompatible with the application (BASH is recommended)

From your help page you mentioned this error is related to another issue. I need assistance analyzing resolving this issue.

Please attach a full log file showing the problem (using the latest version of WinSCP).

To generate log file, enable logging, log in to your server and do the operation and only the operation that causes the error. Submit the log with your post as an attachment. Note that passwords and passphrases not stored in the log. You may want to remove other data you consider sensitive though, such as host names, IP addresses, account names or file names (unless they are relevant to the problem). If you do not want to post the log publicly, you can mark the attachment as private.

I'd have to see logs from the other servers to know what is different, but:
- You connect with SFTP protocol, what the server rejects.
- So WinSCP falls back to SCP protocol.
- For that it starts a shell.
- But your shell actually starts some kind of interactive menu that WinSCP obviously cannot "talk to".
You need to get rid of the menu to make WinSCP work. Or if you really mean to use SFTP, check why it does not work on the server.
Do you expect this server to behave the same as the other two?

Please see attached logs.

I have attached examples of successful logins to dvorc001 and dvorc002 and an example of the failed log in to dvorc003.

As I understand you mentioned WinSCP attempts to connect to the server using SFTP and as you see in the attached logs that is the protocol we use. What I don't understand is why WinSCP is falling back to an SCP protocol. It shouldn't do that for us as far as i know.

Thanks.

There's absolutely no difference in WinSCP configuration between dvorc001 and dvorc003 logs. So it's something on the server-side.

With dvorc001 and dvorc002, the SFTP works ok.
