[Chrootssh-users] Using CHROOT ssh on FreeBSD 4.8

[Krux <kr...@th...>]

I installed openssh-3.6.1p1-chroot on a FreeBSD 4.8 system, setup the chroot
environment correctly  chroot /chrootdirectory /bin/sh worked
The problem is when users log in, they are not getting chrooted.

here is what I get

%sftp localhost
Connecting to localhost...
krux@localhost's password:
sftp> pwd
Remote working directory: /usr/home/krux
sftp> exit


here is the debug log
