Re: Chrooted sftp setup accessible with psftp, but not sftp

Out of interest, how is this shell created? The default shell is
/bin/false, and sending a command through with ssh (eg `ssh
user@server ls -l .`) does nothing.

Sure,
http://www.bluebottle.net.au/sshd_config.txt
http://www.bluebottle.net.au/sftp-sshd-full.txt
http://www.bluebottle.net.au/sftp-sftp-full.txt

Now that I know psftp is doing special stuff to get a 'sftp' session
working, is the issue something relating to sftp-server not being in
the chroot? The sshd_config manpage entry for ChrootDirectory seems to
state this isn't neccessary, but I could be misreading.
