Hoi Olivier,

Prettig met u kennis te maken! Dank u for the reply.. :o)

I'm using jailkit 2.0.  All binaries are in /usr/sbin.

/etc/passwd contains the correct path, i.e. /usr/sbin/jk_chrootsh

<jail>/dev contains 'tty' 'log=' 'urandom'

su - takes me straight into the jail. No problem.  As does,
su <jailuser>  All then looks and works aok.

sorry I meant 'su - <jailuser>', does that work?

ssh'ing in from an external ( or local ) machine gives the following

    ssh address@hidden
    address@hidden's password:
    Last login: Mon Jul 3 23:12:22 2006 from xxx.xxx.xxx.xxx
    /usr/sbin/jk_chrootsh: no such file or directory

if you manually start /usr/sbin/jk_chrootsh, what happens? it should give you some log message.

Checking /var/log/auth/* shows username and password are accepted,
but that the new entry /dev/pts/x fails to be created.

Maybe something being copied that should'nt be when I issue the command,
jk_init -v /<jail>  ssh ??

possibly, the defaults in jk_init.ini are taken from a Debian machine, so there could be files missing..

I've been trying figure out the differences between the two installs.
The one behaving itself is on a self-compiled distro based on Crux,
2.6.xx kernel.

The one not, is on a 2.2 version of Trustix, 2.4.xx

is it using SELinux ?

'strace' might be the best option to debug this further..
