Hi Stefan, I haven't worked with this for a while now, but I can set up an environment to test this one of these days.
In the code you are using "ftp://"; as virtual file system but in the logs I see "sftp://";. So it was working when your client was using "ftp://"; and your VFS was using "ftp://"; too? And now you want your VFS to be "sftp://";? Have you tried with "ftps://" for the VFS? As sftp goes over SSH a different VFS provider is used. As for the approach, I am not 100% sure but I don't think you have to call the createFileSystemView method, that should be done automatically; this part might be superfluous: BaseUser vfsUser = new BaseUser(); vfsUser.setName(ftpUserHetzner); vfsUser.setPassword(ftpPwdHetzner); vfsUser.setHomeDirectory("/"); vfsFileSystemFactory.createFileSystemView(vfsUser); Cheers, Frank ________________________________ From: Stefan Ziegler <stefan.ziegler...@gmail.com> Sent: Sunday, November 1, 2020 8:20 PM To: ftpserver-users@mina.apache.org <ftpserver-users@mina.apache.org> Subject: Problems with sftp and vfs Hi I'm setting up a plain ftp server in front of another ftp server as virtual file system. This works great since the ftp server used in the virtual file system does not allow anonymous logins. Switching from plain ftp to ftps in the virtual file systems ftp server I'm not able to download files anymore. It still shows the directories but when trying to download a file it seems like it stalls somehow. According to the logs it seems that it tries to download as "anonymous" user and not the user from the virtual file system ftp server (but I can misinterpret this). Has anyone an idea or some hints? Do I mess up something in my code (with the users)? Thanks for any help. See code and logs below. best regards Stefan PropertiesUserManagerFactory userManagerFactory = new PropertiesUserManagerFactory(); UserManager userManager = userManagerFactory.createUserManager(); BaseUser user = new BaseUser();
