openssh unix dev - May 2012 - Is there any method, with ChrootDirectory and internal-sftp, to automatically cd to a subdir on login?

Hi,

This is either a query or a feature request. I have a system where sftp
users are chrooted using scponly, which while requiring much more setup than
OpenSSH's internal-sftp method, has the useful feature of allowing an
initial chroot to a subdirectory, typically the one used for file exchange.
I've searched for a way to do the same thing with OpenSSH. So far
haven't
found it.

If there is a way, then I can transparently substitute it. Otherwise users
would have to do the cd themselves. That's not trivial in my case since a
number of the users run scripts which assume that they'll simply drop in
their correct directory on login.

Thanks for any advice, or consideration of this as a future feature if
there's no present method to achieve it.

Quoting sshd_config(8):

     ChrootDirectory
             Specifies the pathname of a directory to chroot(2) to after
             authentication.  All components of the pathname must be root-
             owned directories that are not writable by any other user or
             group.  After the chroot, sshd(8) changes the working directory
             to the user's home directory.

So set the home directory to what you want them to land in, relative
the ChrootDirectory root.

Right. Sorry for the confusion. Their home directory should be /files,
which would map to /home/user1/files, but you set it to /files
