[Jailkit-users] jk_lsh auto-disconnecting ssh connection

[Jiho Kang]

Hi, I am running ubuntu 9.04 server with jailkit 2.10.

when I try to ssh login to a chrooted user using SecureCRT 6, jk_lsh disconnects the connection.
this is what /var/log/auth.log says.

hmm... it seems I "tried to get an interactive shell session" but can't find any relevant data on what that means.
SFTP is working fine and ssh works only when i change the users shell from /usr.sbin/jk_lsh to /bin/bash.

here are some configs.

> /etc/passwd
>   test:x:1012:1001::/home/chroot/./home/test:/usr/sbin/jk_chrootsh
>
> /home/chroot/etc/passwd
>   test:x:1012:1001::/home/test:/usr/sbin/jk_lsh
>
> /home/chroot/etc/jailkit/jk_lsh.ini
>   [group jail]
>   paths = /usr/bin, /usr/lib, /bin, /usr/sbin
>   executables = /usr/bin/ssh, /usr/bin/scp, /usr/lib/sftp-server, /usr/lib/openssh/sftp-server

any hits would be appreciated.
thanks in advance.
