Re: SFTP - Connecting with Zlib compression?

See "Enable compression" at:
https://winscp.net/eng/docs/ui_login_ssh

Though, I'm sure your Java problem is not about ZLib.

Check the JSch log. See also my answer to:

SFTP - Connecting with Zlib compression?

2022-04-20 16:31

What do I need to do to enable Zlib compression within WinSCP? I'd like to test whether the SFTP server I'm connecting to supports Zlib compression or not.

Full context:
When connecting to the SFTP server with a Java application, I'm getting the error

Caused by: com.jcraft.jsch.JSchException: Algorithm negotiation fail

When connecting with WinSCP I'm not able to reproduce the error. I'd like to investigate whether the difference is the compression algorithm the clients are using.
