Re: Different root and initial directories for SFTP

[Guillaume Nodet]

Ah, I see.
It's currently not supported unfortunately : please raise a JIRA for that.
In the mean time, you should derive the SftpSubsystem class and override
the getDefaultDirectory method to return the Path you want for the given
user.

Re: Different root and initial directories for SFTP

[Quinn Stevenson]

Yeah - I’ve tried that.  What it does is set’s the root of the virtual 
filesystem to a different spot for that user.  So if I set the defaultHomeDir 
to target/sftp and the userHomeDir for my test user to target/sftp/home/user, 
the “root” of the virtual filesystem is target/sftp/home/user.  What I need is 
the root of the virtual filesystem to be target/sftp, and the initial/login 
directory for the user to be target/sftp/home/user.

I think I need to set the “current directory” for the user when they login, but 
I have no idea how to do that on the SSHD server.

Hopefully that helps describe what I’m trying to do.

Re: Different root and initial directories for SFTP

[Guillaume Nodet]

Have you tried setting home dirs for your users on the VirtualFileSystemFactory
?

vfsf.setUserHomeDir("the user", the_home_dir);
