[Jailkit-users] sftp question

[Paul Mitchell]

Hello,
   I've just loaded jailkit onto a redhat 5 server, following the advice 
on http://olivier.sessink.nl/jailkit/howtos_chroot_shell.html (with 
additional help from the sftp&scp only page).

At the moment, I can ssh onto the server and it effectively jails the 
user.  I can also scp a file to the server.

Unfortunately, this server will server as a "landing zone", or drop off 
box for users, predominantly running Windoze.  I need to get sftp to work 
as well, but as yet, have been unsuccessful.

Here's what I've done:

1) modified /etc/ssh/sshd_config:

Subsystem       sftp    /home/jail/usr/libexec/openssh/sftp-server

2) modeified the executables line in both /etc/jailkit/.jk_lsh.ini and 
/home/jail/etc/jailkit/jk_lsh.ini:

 grep sftp /etc/jailkit/jk_lsh.ini
executables= /usr/libexec/openssh/sftp-server
address@hidden jailkit]# grep sftp /home/jail/etc/jailkit/jk_lsh.ini
executables= /usr/libexec/openssh/sftp-server

3) ran jk_init -v -j /home/jail sftp scp

4) jk_init -v -j /home/jail jk_lsh

The /var/log/messages file shows that I've connected:

scp and ssh work, sftp dumps me right out. All help with this would be 
appreciated.

Thanks,
