5.0.1 appimage doesn't work with WINSCP（mobaxterm & xshell works fine）

[andersen933]

try to use a WINSCP client to connect a ssh-mitm server；it doesn't work and return a banner information；mobaxterm /xshell /secureCRT works fine. is it a bug? or i need to config something?

SSH-MITM uses Python paramiko for handling SSH.

Paramiko has known problems with ssh clients and servers, so SSH-MITM needs patches for paramiko, which are not merged in paramiko itself (paramiko/paramiko#2083)

Note: Those patches are included in SSH-MITM and paramiko is patched during runtime, so you don't need a custom version of paramiko.

List of tested SSH clients: paramiko/paramiko#2083 (comment)

Since there are a lot of different SSH implementations, it's a very time consuming task to test each client. WinSCP is based on PuTTY, but perhaps there are some differences in the implementation and how WinSCP is using PuTTY's library.

@andersen933 Can you provide more information, please.

@andersen933 SFTP connections are broken in some situations. The subsystem for SFTP was started before the connection to the remote serve was established. In such situations the SFTP connection was closed.

I have implemented a bug fix. The subsystem is now waiting for the server connection to be established.

I will create a new release in the next few days.
